Description

Technical Field

[0001] This utility model belongs to the field of forest waste treatment technology, and in particular relates to a fermentation and crushing equipment for forest vegetation waste. Background Technology

[0002] Forest waste generally refers to the residues left after logging, timber processing, and wood utilization, including branches, twigs, felled roots, tops, shrubs, dead and fallen trees, bark, root ends, cut ends, sawdust, wood chips, etc.

[0003] Grass and wood waste can generally be returned to the environment through natural degradation. However, natural degradation is slow. In order to get grass and wood waste into the natural cycle as soon as possible, human intervention is needed to crush and ferment the grass and wood waste before returning it to the environment.

[0004] Grass and wood waste is usually shoveled directly from the ground by workers and added to the crushing equipment. Inevitably, grass and wood waste will be mixed with debris such as gravel and soil. This debris will affect the working efficiency of the crushing equipment and may even cause damage to the crushing equipment. Therefore, a fermentation and crushing equipment for forest grass and wood waste is proposed. Utility Model Content

[0033] The separation mechanism includes a water tank 5 containing water, and a feeding assembly is rotatably connected to the water tank 5, with the lower part of the feeding assembly submerged in the water.

[0034] When the device of this utility model is working, the plant waste is first fed into the water tank 5 inside the outer shell 1. The density of debris such as gravel and soil is greater than that of water, so it sinks to the bottom of the water tank 5. The plant waste floats on the water surface and is fed into the crushing mechanism by the feeding component.

[0038] One side wall of the crushing chamber 15 extends into the water tank 5 and slides in contact with the feeding roller 11. Multiple through slots 25 are provided on one side wall of the crushing chamber 15, and the multiple through slots 25 are corresponding to the multiple feeding rods 12.

[0039] In one alternative, the bottom of the water tank 5 is connected to a collection box 7, and one side of the collection box 7 is connected to a discharge port. The discharge port is located on the side wall of the outer shell 1, and a sealing plate 24 is detachably connected to the discharge port by bolts.

[0040] An inclined filter screen 8 is fixed inside the collection box 7, with the lower end of the filter screen 8 flush with the bottom edge of the discharge port.

[0041] In one alternative, the bottom wall of the collection box 7 is inclined, and the lower end of the bottom wall of the collection box 7 is connected to the inlet of the water pump 9. The outlet of the water pump 9 is connected to the side wall of the water tank 5 through the hose 10, and the connection between the hose 10 and the water tank 5 is away from the feeding roller 11.

[0042] The hose 10 is equipped with a three-way valve, one of the outlet ends of which is fixed to the outer casing 1. The three-way valve is opened at regular intervals to release water.

[0043] In one alternative, a motor 13 is fixedly connected inside the outer casing 1, and a double sprocket 14 is coaxially fixedly connected to the output shaft of the motor 13. The double sprocket 14 is connected to the second sprocket 22 and the first sprocket 21 respectively via two chains. The second sprocket 22 is coaxially fixedly connected to one end of the first roller shaft 23 that extends out of the water tank 5. The water tank 5 is coaxially fixedly connected to one end of one of the second roller shafts 17 that extends out of the crushing chamber 15.

[0048] In one alternative, the discharge end of the crushing chamber 15 is connected to a discharge pipe 19, which extends out of the outer casing 1.

[0049] Specific work process:

[0050] A roller 2 is provided at the bottom of the outer casing 1. The roller 2 is a universal wheel with a self-locking function. A handle 3 is provided on one side of the outer casing 1 to facilitate workers to move the device of this utility model.

[0051] After the device of this utility model is moved to the designated position, the roller 2 is fixed to prevent the outer casing 1 from moving. The worker feeds the waste materials into the feed hopper 4, and then the waste materials enter the water tank 5. The density of gravel, soil and other debris is greater than that of water, so they sink to the bottom of the water tank 5. The waste materials float on the water surface. The motor 13 drives the double sprocket 14 to rotate. The double sprocket 14 drives the second sprocket 22 to rotate through the chain. The second sprocket 22 drives the first roller shaft 23 to rotate, which in turn drives the feeding roller 11 to rotate. The feeding rod 12 on the feeding roller 11 moves the waste materials. Above the crushing chamber 15, larger and heavier pieces of grass and wood waste are thrown into the crushing chamber 15 under the action of centrifugal force. Lighter and smaller pieces of grass and wood waste are blocked by the side wall of the crushing chamber 15 when the feeding rod 12 passes through the through groove 25 and fall into the crushing chamber 15. The grass and wood waste falls onto the two crushing rollers 16. The double sprocket 14 drives the first sprocket 21 to rotate through the chain. The first sprocket 21 drives one of the second roller shafts 17 to rotate. The two second roller shafts 17 are connected by a gear 20, which drives the crushing teeth 18 to move and crush the grass and wood waste.

[0052] Water in the water tank 5 flows into the collection box 7, and debris such as gravel and soil falls onto the filter screen 8. Every certain period of time, the sealing plate 24 is opened to remove the debris. Water returns to the water tank 5 through the water pump 9 and the hose 10, and the connection between the hose 10 and the water tank 5 is far away from the feeding roller 11, which pushes the waste grass and wood towards the feeding roller 11.
