Description

Technical Field

[0001] The utility model relates to the technical field of biomass crushers, and more specifically, to a feeding device for a biomass crusher. Background Art

[0002] A biomass crusher is a device specifically used for crushing biomass raw materials such as agricultural and forestry waste, straw, branches, and fruit shells. It converts raw materials into small pieces or granular fuels that are easy to store and transport through efficient crushing. With its high crushing efficiency, wide application fields, and intelligent monitoring system, the biomass crusher has become an indispensable device in the process of biomass energy utilization. By continuously optimizing the design and improving the performance, the biomass crusher will play a greater role in the fields of environmental protection and renewable energy in the future.

[0003] Chinese Patent Application No. CN201820880745.5 discloses a feeding device for a biomass fuel crusher, which includes a drying part and a dust removal part; the drying part includes a drying chamber and a heating device. The drying chamber is of a cylindrical structure. An inlet is arranged at the top of the drying chamber, and an outlet is arranged at the bottom of the drying chamber. A first electric gate is arranged at the outlet; the heating device is also arranged at the bottom of the drying chamber; the dust removal part includes a dust removal chamber and a suction fan. The dust removal chamber is of a cylindrical structure and is arranged at the bottom of the drying chamber. The dust removal chamber is communicated with the drying chamber through the first electric gate; a suction fan is arranged on the left side surface of the dust removal chamber, and the suction fan is communicated with the inside of the dust removal chamber through an air duct; a second electric gate is arranged at the bottom of the dust removal chamber;

[0004] In the above technical solution, the heating and drying operation and the dust removal operation are carried out separately to dry and remove dust from the raw materials, prevent wet raw materials from entering the crusher and affecting the operation of the crusher, and at the same time remove dust to improve the product quality. However, for larger crushers, the length of the crushing roller is relatively long. When the conveying device transports the biomass raw materials above the crushing roller, they are usually piled up at the middle position of the crushing roller for crushing, while there is no material or very little material at both ends of the longer crushing roller, which affects the crushing speed of the crushing roller for the material, and further affects the crushing efficiency of the crushing roller for the material. Sometimes, it is necessary for personnel to level the material with a spreading plate, which will increase the risk of injury to the personnel. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a feeding device for a biomass crusher to solve the problems raised in the above background art:

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A feeding device for a biomass crusher, comprising a crusher body and a crushing device arranged inside it. Opposite surfaces of the crusher body are respectively fixedly installed with a first fixing frame and a second fixing frame. The end surfaces of the first fixing frame and the second fixing frame are jointly fixedly installed with a feeding port.

A slider is slidably connected inside the sliding groove. One end of the slider is fixedly connected with the surface of the blanking bin.

[0008] By adopting the above technical solution, the forward and reverse rotation of the motor drives the rotation of the rotating shaft and the gear. The forward and reverse rotation of the gear drives the horizontal reciprocating movement of the toothed plate. At this time, the blanking bin follows the toothed plate to reciprocate, and the materials inside the feeding port are evenly scattered on the surface of the crushing device through the blanking bin. Compared with the existing middle accumulation of materials, the crushing speed of the crushing device for the materials is improved, and further the crushing efficiency of the crushing device for the materials is improved. There is no need for personnel to level with a spreading board, thus avoiding the injury of personnel.

[0009] Preferably, a motor is fixedly installed on the bottom end surface of the second fixing frame. The output end of the motor is fixedly connected with the rotating shaft.

One end of the spring is fixedly connected with the surface of the slider, and the other end of the spring is fixedly connected with the inner wall of the sliding groove. The slider is elastically connected with the sliding groove through the spring.

[0017] By adopting the above technical solution, the blanking bin reciprocates along with the toothed plate. At this time, the blanking bin drives the slider to reciprocate in the chute and squeeze the spring. Under the action of the spring, the blanking bin makes the laying of materials more uniform during the reciprocating movement, and at the same time increases the stability of the blanking bin during movement.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] 1) When the feeding device of this biomass crusher is in use, the motor rotates forward and backward to drive the rotating shaft and the gear to rotate. The gear rotates forward and backward to drive the toothed plate to reciprocate horizontally. At this time, the blanking bin reciprocates along with the toothed plate, and the materials inside the feeding port are evenly scattered on the surface of the crushing device through the blanking bin. Compared with the prior art where materials accumulate in the middle, the crushing speed of the crushing device for materials is improved, and thus the crushing efficiency of the crushing device for materials is improved. There is no need for personnel to level with a spreading board, thereby avoiding personal injuries.

[0020] 2) When the feeding device of this biomass crusher is in use, the blanking bin reciprocates along with the toothed plate. At this time, the blanking bin drives the slider to reciprocate in the chute and squeeze the spring.
