Description

Measuring device for single spike length of rice Technical Field The utility model belongs to the technical field of crop measurement, and particularly relates to a measurement device for the single spike length of rice. Background The ear length of the rice is directly related to the yield, and is an important index for sowing the rice. Ear length is defined as the length from the neck to the tip (not connecting with the awn). In general, the ear length of each rice ear of rice is manually measured before rice maturing and harvesting. When in measurement, the rice ears need to be straightened first, hands are easily cut by the ears or leaves, and mature rice ears are easy to drop. And moreover, a large amount of manpower and material resources are consumed in long-time measurement and observation, the measurement result is easily influenced by personal factors such as fatigue of measurement personnel, and the subjective error is large. In the existing measurement process of the ear length of a single rice ear, the rice ear is fluffy, one person is required to collect the rice ear manually, meanwhile, the other person is required to measure the ear length of the collected rice ear by using a tape measure and the like, so that the measurement is time-consuming and labor-consuming, and the measurement accuracy is low. Disclosure of utility model In order to solve the problems, the utility model adopts the following technical scheme: A measurement device for rice spike length, comprising: The placing plate is provided with a placing groove for placing rice; The limiting component is connected to the placing plate so as to limit the rice in the placing groove; The folding bag is arranged in the placing groove and is connected with the limiting component so as to fold rice ears in the placing groove; And the measuring assembly is connected with the placing plate and is correspondingly arranged with the placing groove so as to measure the spike length of the rice in the placing groove. Further, two sliding grooves are formed in the placement plate, the two sliding grooves are respectively formed in two ends of the placement plate in the width direction, and the sliding grooves extend along the length direction of placement. The limiting assembly comprises a first limiting plate and a second limiting plate, wherein the first limiting plate is arranged on the placing plate, two ends of the first limiting plate are respectively arranged in the two sliding grooves, the second limiting plate is arranged at one end, far away from the first limiting plate, of the placing plate, and two ends of the second limiting plate are respectively and slidably arranged in the two sliding grooves. Further, the first limiting plate and the second limiting plate are of an arch structure. The folding bag is in a horn shape, the large opening end of the folding bag is connected with the second limiting plate, the small opening end of the folding bag penetrates through the first limiting plate and extends towards the end of the placing groove, and the folding bag is used for folding rice in the placing groove. Further, the placing plate is provided with a positioning groove, and the positioning groove is arranged at one end far away from the sliding groove and is parallel to the placing groove. Further, the measuring assembly comprises a laser range finder and a positioning block, wherein the laser range finder is arranged at one end, close to the first limiting plate, of the positioning groove, and the positioning block is slidably arranged in the positioning groove. Further, a first groove is formed in one end, close to the first limiting plate, of the placing plate, a fixing plate is rotatably connected to the placing plate, a second groove is formed in the fixing plate, and the first groove is matched with the second groove to fix stalks at the root of the rice ears. Further, scale marks are arranged at one end, close to the positioning block, of the placing plate. The beneficial effects are that: According to the device for measuring the single-ear-length of rice, disclosed by the utility model, the rice ears are folded through the folding bag, the laser range finder and the scale marks are used for reading the ear length of the single rice ear twice, so that the measurement accuracy is ensured, and the time and the labor are saved. Drawings FIG. 1 is a schematic diagram of the overall structure of a device for measuring the single spike length of rice according to the utility model; FIG. 2 is an enlarged view of FIG. 1 at A; FIG. 3 is a plan view of the apparatus for measuring the single ear length of rice according to the present utility model; The device comprises a placing groove, a placing plate, a second limiting plate, a folding bag, a first limiting plate, a fixing plate, a second groove, a first groove, a laser range finder, a positioning groove, a positioning block, a sliding groove and a positioning block.
