Description

Technical Field

[0001] This utility model relates to agricultural and forestry machinery, and more particularly to a crushing device that integrates forced feeding and ultrafine crushing of fruit tree branches. Background Technology

[0002] Fruit tree planting involves extensive pruning every year. Due to the large amount of pruning, the disposal of pruned branches presents certain difficulties. As environmental protection awareness becomes increasingly standardized, branches cannot be burned. Storing pruned branches also requires a lot of space, and long-term accumulation poses a fire hazard. Some branches contain certain cellulose and sugars, which can be added to livestock feed after ultrafine grinding, representing a way to recycle waste. However, branches containing cellulose and sugars are generally quite soft, and using existing grinders can easily cause them to entangle. The softness of the branches also makes the grinding and feeding process very difficult and prone to danger. Utility Model Content

[0003] The purpose of this invention is to provide a device for forced feeding and ultra-fine crushing of branches, namely a forced feeding fruit tree branch crusher.

[0004] The purpose of this utility model is achieved through the following technical solution: a forced feeding fruit tree branch crusher, comprising a power unit, a material conveying unit, a crushing unit and an output unit, characterized in that a forced feeding mechanism is provided on the material conveying unit, and the output unit is located at the bottom of the crushing unit, and the output unit consists of a fan and an air duct.

[0005] The purpose of this utility model can also be achieved in the following way: the forced feeding mechanism is installed at the feed inlet of the material conveying device, and the forced feeding mechanism consists of a feeding roller, a feeding roller reducer, and a feeding roller motor.

[0006] The forced feeding mechanism is a floating feeding mechanism, which has the function of adjusting the gap between the feeding roller and the transmission belt according to the different diameters of the branches, so as to realize the forced feeding of branches of different thicknesses.

[0007] The material conveying device consists of a frame, a conveyor motor, a conveyor belt, and two conveyor belt shafts. The conveyor belt shafts are installed at both ends of the frame, and the conveyor belt wraps around the conveyor belt shafts at both ends. The conveyor motor is installed on the frame and connected to the conveyor belt shaft at one end.

[0008] The crushing device is a hammer mill, which consists of a crusher base, a crusher cover, a bearing seat, hammers, a small pulley, a crusher rotor, and a screen. The material is crushed by the hammers at high speed and collides with the crusher cover. When the crushed size is smaller than the screen hole diameter, the material falls into the air duct of the output device and is conveyed out by wind.

[0009] The power unit consists of a crushing motor, a large pulley, and a belt. The crushing motor drives the small pulley on the hammer mill through the large pulley and the belt, thereby transmitting power to the hammer mill.

[0010] The present invention has the following advantages: (1) It can force the crushing and feeding, and has a certain adaptability to the softness, hardness and diameter of the material, which greatly improves the crushing efficiency; (2) It can perform ultra-fine crushing, and different diameter screens can be replaced as needed to achieve different crushing effects; (3) It can reduce the personal injury that may be caused by manual feeding and improve the safety of operation.

[0018] See appendix Figure 1-6 A forced-feed fruit tree branch shredder includes a power unit, a material conveying unit, a shredding unit, and an output unit. The shredding unit is characterized by having a forced-feed mechanism on the material conveying unit and an output unit located at the bottom of the shredding unit. The output unit consists of a fan (located on one side of the shredder base, not shown in the figure) and an air duct (a cylindrical channel is provided at the bottom of the shredder base 4.1 by raising the base).

[0019] The crushing motor 1 transmits power through the belt 3, and the acceleration effect is generated by the diameter difference between the large pulley 2 and the small pulley 4.5 on the hammer mill 4.

[0020] The power unit consists of a crushing motor 1, a large pulley 2, and a belt 3. The crushing motor 1 drives the small pulley 4.5 on the hammer mill 4 through the large pulley 2 and the belt 3, thereby transmitting power to the hammer mill 4.

[0021] The hammer mill 4 consists of a mill base 4.1, a mill cover 4.2, a mill bearing seat 4.3, hammers 4.4, a small pulley 4.5, a mill rotor 4.6, and a screen 4.8. Inside the mill, the material is struck at high speed by the hammers and collides with the mill cover. When the pulverized size is smaller than the diameter of the screen openings, the material falls into the air duct of the output device and is conveyed out by airflow.

[0022] The forced feeding mechanism is a floating feeding mechanism, which has the function of adjusting the gap between the feeding roller and the conveyor belt according to the different diameters of the branches, so as to achieve forced feeding of branches of different thicknesses. It mainly consists of feeding roller 7, feeding roller reducer 8, feeding roller motor 10, and forced feeding mechanism frame 5. The material is transported to the feed inlet of the crusher by the conveyor belt 11 and forced into the crusher 4 by the feeding roller 7. The forced feeding mechanism adjusts the gap between the feeding roller and the conveyor belt according to the different diameters of the material to achieve forced feeding of branches of different thicknesses.

[0023] Example: When crushing is required, first adjust and fix the gap between the feeding roller and the conveyor belt according to the diameter of the material. Then, place the material on the conveyor belt 11, and drive the conveyor belt forward by the conveyor belt motor. The feeding roller 7 on the forced feeding mechanism forces the material into the hammer mill 4. After being hammered and collided at high speed by the hammers 4.4, the crushed material leaks out from the screen holes of the screen 4.8 into the air duct of the output device. Then, under the action of the air force blown by the fan, it is conveyed to the receiving device, completing the crushing process.
