Description

Forest tree waste granulating device Technical Field The utility model belongs to the technical field of granulation, and particularly relates to a forest waste granulating device. Background Pine wood nematode disease, also known as pine tree wilting, is a destructive epidemic of pine trees, which is caused by pine wood nematodes parasitic in pine tree bodies, and is a major hazard to pine plants. The disease has strong pathogenicity, fast death speed of hosts, fast transmission and great treatment difficulty. The treatment means of pine wood nematode epidemic wood is incineration and biomass fuel particle preparation. Compared with incineration, the method has the advantages that the wood waste is processed into wood particles and used as biomass fuel, so that the method becomes an environment-friendly and economic treatment mode. The wood particles have the advantages of high density, high energy content, convenience in storage and transportation and the like, and are widely applied in the field of energy. But when some saw-dust more is poured into slightly to the prilling granulator of prior art, the rotation of compression roller through the through-hole of mould dish with saw-dust extrusion can make the inside saw-dust of device extrude each other and solidify, causes the unsmooth resistance that increases equipment operation that flows, consequently causes the jam stall of equipment easily, influences production efficiency. In view of the above, the present inventors have made intensive studies to solve the above-mentioned drawbacks of the prior art. Disclosure of utility model Therefore, the utility model aims to provide a wood waste granulating device, which solves the problems that when more wood chips are poured, the wood chips in the device are mutually extruded and solidified by a compression roller when the compression roller extrudes the wood chips through the through holes of a die plate, so that the flowing is unsmooth, the running resistance of equipment is increased, the equipment is blocked and stopped, and the production efficiency is affected. The utility model solves the technical problems by the following technical means: The utility model provides a forest waste prilling granulator, includes the barrel, the barrel top is equipped with the feed inlet, the inside fixed mounting of barrel has the mould dish, mould dish inner circle bottom is equipped with the ring gear, the inside mount pad that is equipped with of barrel, fixed mounting has driving motor on the mount pad, driving motor's output fixedly connected with pivot, fixed mounting has the connecting rod in the pivot, the connecting rod other end rotates and is connected with the compression roller, the compression roller meshes with the ring gear mutually, pivot top fixed mounting has the cutting rod, a plurality of groups of through-holes have been seted up to the mould dish bottom, every group of through-hole all slidable mounting has the ejector pin, be connected with the spring between ejector pin and the mount pad, driving motor's output fixed mounting has the connecting rod, connecting rod other end fixed mounting has the voussoir, inside fixed mounting of barrel has the material receiving dish, the discharge gate has been seted up on the barrel. On the basis of the technical scheme, the utility model also carries out the following improvement: Further, the distance between the cutting rod and the outer ring of the die plate is between 10mm and 30 mm. The length of the formed wood particles is kept in the range favorable for stable combustion by the aid of the structural design, so that the problems that the combustion speed is too high, the combustion process is unstable, flame jump, extinction and the like occur or ventilation is unsmooth due to too long length of the wood particles and the like are avoided when the wood particles are burnt, and the combustion stability is influenced. Furthermore, the sweeping plate is fixedly arranged at the bottom of the cutting rod, and the sweeping plate sweeps wood particles falling onto the receiving tray from the cutting rod to the discharge hole along with the rotation of the cutting rod, so that the wood particles are discharged conveniently, and the wood particles are prevented from being accumulated in the receiving tray. Furthermore, the top surface of the ejector rod is flat with the upper surface of the bottom of the die plate in the natural state of the spring, and the structural design does not interfere the rotation of the compression roller on the die plate, and can smoothly jack up and fall back along with the rotation of the wedge block, so that the wood chips which are extruded and condensed together are scattered, and the phenomenon that the equipment is blocked and stopped is prevented. Furthermore, the aperture size of the die plate is between 6mm and 8mm, and the wood particles with the diameter range can achieve higher combustion efficiency during combustion,
