Description

Technical Field

[0001] This utility model relates to the technical field of feed processing equipment, specifically a dust-free feed crushing and unloading device. Background Technology

[0002] Feed refers to scientifically formulated and processed food ingredients or mixtures used to feed livestock, poultry, aquatic animals, and other animals, aiming to meet the various nutrients required for animal growth, development, reproduction, and health maintenance. It can be classified by source into plant-based feed, animal-based feed, mineral feed, and artificial additives; and by form into powder, pelleted feed, and liquid feed. Modern feed production emphasizes nutritional balance, safety, and conversion efficiency, which are crucial foundations for achieving large-scale and efficient livestock farming.

[0003] Feed production requires the use of crushing equipment to crush raw materials. However, existing crushing equipment generates a large amount of dust during the crushing process. The dust spreads and pollutes the workshop and surrounding air, affecting the working environment. Long-term inhalation of dust can easily cause respiratory diseases or allergic reactions in workers.

The invention proposes a dust-free feed crushing and unloading device, which prevents dust from flying during the crushing process through a feeding mechanism, a dust removal mechanism to prevent dust from flying during feeding, and a dustproof cloth pipe to prevent dust from flying when the material is discharged.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a dust-free feed crushing and unloading device, including a frame mechanism, a feeding mechanism, and a dust removal mechanism.

[0023] See Figures 1-4A dust-free feed crushing and unloading device includes a frame mechanism 1, a feeding mechanism 3, and a dust removal mechanism 4. A crushing mechanism 2 is fixedly installed on the top of the frame mechanism 1, and the feeding mechanism 3 is fixedly installed on top of the crushing mechanism 2. The feeding mechanism 3 includes a feeding cylinder 301. The dust removal mechanism 4 includes a housing 401 and two sets of dust suction heads 408. The two sets of dust suction heads 408 are located inside the feeding cylinder 301. A dust suction port is provided at the bottom of the feeding cylinder 301, and a dust suction port is provided at the top of the housing 401. Two sets of connection ports 402 are fixedly connected to one side of the vacuum head 408 via connecting pipes. The inside of the housing 401 is provided with a material storage chamber 403, and a dust collection box 407 is detachably installed inside the material storage chamber 403. A filter chamber 404 is provided on the top of the housing 401, and a fine filter screen 406 is detachably installed inside the filter chamber 404. A fan 405 is fixedly connected to the top of the filter chamber 404. A coarse filter screen 409 is provided at the bottom of the vacuum head 408.

[0024] The feeding mechanism 3 also includes two sets of return springs 303. Two sets of return springs 303 are rotatably installed inside the feeding cylinder 301. One end of the return spring 303 is fixedly connected to the inner wall of the feeding cylinder 301, and the other end of the return spring 303 is fixedly connected to the top of the baffle 302. A limit block 304 is fixedly installed inside the feeding cylinder 301. The limit block 304 is located on the top of the baffle 302. A pressure switch is provided at the bottom of the limit block 304. When the pressure switch is open, the fan 405 is started. When the pressure switch is closed, the fan 405 is turned off. The pressure switch makes the fan 405 run only when feeding to reduce energy waste.

[0025] The frame mechanism 1 includes a mounting frame 101, with a counterweight 102 fixedly installed at the bottom of the mounting frame 101. The counterweight 102 lowers the overall center of gravity of the equipment to ensure the stability of the equipment during operation. Several shock-absorbing legs 103 are fixedly installed at the bottom of the counterweight 102 to absorb the vibration generated during the operation of the equipment and improve the stability of the equipment. The crushing mechanism 2 includes a crusher body 201 and a motor 202. Both the motor 202 and the crusher body 201 are fixedly installed on the top of the mounting frame 101. The output shaft of the motor 202 is fixedly connected to one side of the crusher body 201 through a coupling. A discharge port 203 is provided at the bottom of the crusher body 201. A dustproof cloth pipe 204 is fixedly connected to one side of the discharge port 203. The material is discharged through the discharge port 203, and the dustproof cloth pipe 204 prevents dust from flying when the material is discharged.

[0026] This utility model's dust-free feed crushing and unloading device prevents dust from flying during the crushing process through the feeding mechanism 3, the dust removal mechanism 4, and the dustproof cloth pipe 204. In summary, this device has the function of controlling dust at various stages, solving the shortcomings of existing crushing devices that generate a large amount of dust during the crushing process, which pollutes the workshop and surrounding air, affects the working environment, and makes it easy for workers to develop respiratory diseases or allergic reactions if they inhale dust for a long time.

[0027] Specifically, two sets of return springs 303 provide upward pulling force to the baffles 302, and the limit block 304 restricts the maximum rotation angle of the two sets of baffles 302, so that the two sets of baffles 302 seal the internal channel of the feed cylinder 301. When the material enters from the top of the feed cylinder 301, the two sets of baffles 302 can overcome the elastic force of the return springs 303 and rotate downward to open the passage for normal feeding. After feeding is completed, the two sets of baffles 302 will seal the channel to prevent dust from escaping from the bottom of the feed cylinder 301. During the feeding process, the fan 405 is started to generate negative pressure inside the dust suction head 408, which drives the dust through the coarse filter screen 409 into the storage chamber 403. Then, the fine filter screen 406 blocks the dust inside the storage chamber 403 and it falls into the dust collection box 407 for storage. In this process, the coarse filter screen 409 plays a preliminary filtering role, allowing only dust to enter the dust suction head 408 and blocking large pieces of raw materials.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
