Description

Round baler Technical Field The invention belongs to the field of livestock machinery, and particularly relates to a round baler. Background The round baler is a special machine for harvesting pasture, crop straw and other materials, and the round bales produced by the round baler are beneficial to the transportation and commercialization of pasture, crop straw and other resources. The steel roller type round baler is widely used due to the simple structure and convenient use and maintenance. However, the existing steel roller type round baler usually adopts a plurality of round rollers in annular layout to bundle materials, the materials are fed into a baling bin surrounded by the round rollers from above or below, and the materials are rolled into cylindrical bales by continuously feeding the materials and continuously rotating by means of the round rollers in the bundling process. Gaps inevitably exist between the round rollers, materials are easy to leak from the gaps, and the materials do parabolic motion in the bundling chamber, so that a large amount of materials are crushed due to collision and friction with the round rollers, and the crushed materials with smaller sizes are easier to leak, so that serious loss of the materials and resource waste are caused. Taking a common medium-sized round baler as an example, the loss of materials caused by material leakage can reach 10% -15% of the total feeding amount in one working period, and the loss ratio is not small in the loss caused by large-scale operation. In order to reduce the material leakage rate, it is a common practice in the art to reduce the distance between round rollers, for example, a novel grass bundling bin of a round baler disclosed in the Chinese patent application publication No. CN207185280U, and the grass bundling bin of the round baler has small and equal distance between other rollers except a net feeding port and a feeding port, so that the grass leakage amount can be reduced. However, the distance between the round rollers cannot be too small, otherwise, the round rollers are easy to be blocked with fine broken impurities to increase abrasion, or the round rollers cannot smoothly rotate due to the fact that machining errors and assembly errors cannot be accommodated, so that the problem of material leakage cannot be well solved by reducing the distance between the round rollers. Disclosure of Invention The invention aims to provide a round baler, which aims to solve the technical problem of high material leakage rate of the round baler in the prior art. In order to achieve the above purpose, the technical scheme of the round baler provided by the invention is as follows: The utility model provides a circle bundle machine, including the casing and set up the bundling storehouse in the casing, the bundling storehouse is enclosed by the casing left and right sides wall and a plurality of circular rollers that are annular overall arrangement that set up between left and right sides wall, wherein the interval of two circular rollers is great in order to form the breach that is used for feeding, casing upper portion is provided with the feeding storehouse that is used for feeding the material to the bundling storehouse in bundling storehouse front side tilting, be provided with in the casing in bundling storehouse below and be used for collecting and collect the structure of gathering the material, and be used for receiving the storage bin of gathering structural material, the storage bin is located the below of feeding storehouse and is provided with the material conveyer with the feeding storehouse between, be equipped with the secondary feed inlet that supplies the material on the material conveyer to enter into in the feeding storehouse on the diapire of feeding storehouse. As a further improvement, the top of the storage bin is open, the material on the collection structure falls into the storage bin from the open back position, the lower end of the material conveyor is positioned at the open front position, the material conveyor is provided with a belt body capable of rotating circularly and a plurality of material holding parts which are arranged outside the belt body and move along with the belt body, the material holding parts move to the lower end of the material conveyor and hold up the material in the storage bin in the back-and-forth movement process, and the material holding parts move to the upper end of the material conveyor and throw the material into the feeding bin in the front-and-back movement process. As a further improvement, the bottom wall of the feeding bin comprises a feeding bottom wall and a feeding bottom wall which are arranged front and back, the rear end of the feeding bottom wall is located between the front end of the feeding bottom wall and the top wall of the feeding bin, a secondary feeding hole is formed in the space between the rear end of the feeding bottom wall and the front end of the feeding
