A kind of animal husbandry excrement cleaning device for agricultural use

Abstract

The invention relates to an agricultural livestock excrement cleaning device, comprising a conveyor belt, an air outlet cylinder, an air injection cylinder, and a piston assembly b. The air outlet cylinder and the air injection cylinder are both provided with a plurality of air outlet holes. The cleaning assembly comprises a cleaning cylinder arranged on the side of the conveyor belt and a water tank connected to the cleaning cylinder. During the conveying process of the conveyor belt, the piston assembly a and the piston assembly b are driven to perform piston movement. The piston assembly a moves to inject and compress air into the air injection cylinder and drives the air injection cylinder to rotate. When the air outlet holes on the air outlet cylinder and the air injection cylinder coincide, the compressed air in the air injection cylinder is sprayed out to perform air blowing cleaning on the excrement on the conveyor belt. When the piston assembly b performs piston movement, the water in the water tank is drawn into the cleaning cylinder and then sprayed onto the conveyor belt for cleaning. The problem that some excrement contains water and is tightly adhered to the conveyor belt and cannot fall off by its own gravity is solved, and the excrement is easily adhered to in subsequent roller brush cleaning, resulting in a decrease in cleaning effect.

Description

Technical Field

[0001] The invention relates to the technical field of agricultural pollution cleaning, and in particular to an agricultural livestock breeding excrement cleaning device. Background Art

[0002] In animal husbandry, the manure of livestock such as cattle and sheep contains rich organic matter and a variety of nutrients, such as nitrogen, phosphorus, potassium, etc. These nutrients are very important for crop growth and can increase the yield and quality of crops. After being fully decomposed, the manure can promote the reproduction and activity of beneficial microorganisms in the soil, improve soil structure, improve the soil's ability to retain water and fertilizer, and increase the crop's resistance to stress.

[0003] A Chinese patent with application publication number CN116439139A discloses a cleaning and processing equipment for agricultural pollution, including a base frame; an inner support plate connected to the top of the base frame by welding; a transmission drive, which is fixedly connected to the front surface of the base frame by bolts; the automatic collection function of feces can be realized, which greatly improves the feces cleaning efficiency and prevents poultry feces from falling to the ground. When the staff cleans the feces on the ground under the cage, they use tools such as brooms, mops, and cleaning brushes to clean the bottom surface, which is labor-intensive and inefficient, and the feces that penetrate into the cement floor cannot be cleaned, resulting in a strong odor after cleaning, which still causes pollution to the surrounding air.

[0004] However, the inventors found that the device has the following problems: some feces contain moisture and are tightly attached to the conveyor belt and cannot fall off by their own gravity. During subsequent cleaning with the roller brush, feces are easily attached, resulting in a decrease in the cleaning effect. Summary of the invention

[0005] The purpose of the present invention is to address the deficiencies in the prior art and to invent an agricultural livestock breeding manure cleaning device, comprising a conveyor belt, a cleaning component, a washing component, a piston component a, and a piston component b. During the transmission process of the conveyor belt, the piston component a and the piston component b are driven to move. The piston component a continuously injects air into the air injection cylinder and compresses the air. After the air injection cylinder rotates and coincides with the jet hole of the air outlet cylinder, the compressed air is sprayed out to clean the manure on the conveyor belt. The piston component b moves to draw out the water in the water tank and sprays it through the washing cylinder to clean the conveyor belt. Finally, the remaining manure on the conveyor belt is cleaned by a scraper, thereby solving the problem that some manure contains water and is tightly adhered to the conveyor belt and cannot fall by its own gravity, and the manure is easily adhered to during subsequent roller brush cleaning, resulting in a decrease in the cleaning effect.

[0034] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0035] Embodiment 1

[0036] like Figures 1 to 12 As shown, an agricultural livestock excrement cleaning device comprises a conveyor belt 1, a cleaning assembly 2, a cleaning assembly 3, a piston assembly a4, and a piston assembly b5, characterized in that a cleaning frame 6 is arranged at the end of the conveyor belt 1, the cleaning assembly 2 comprises an air outlet a7 and an air outlet b12 arranged on the upper and lower sides of the cleaning frame 6, and an air injection cylinder a8 and an air injection cylinder b14 are respectively slidably arranged in the air outlet a7 and the air outlet b12, and a plurality of air injection holes 9 are staggered on the surfaces of the air outlet a7 and the air outlet b12, and a plurality of air injection holes 13 are opened on the surfaces of the air injection cylinder 8 and the air injection cylinder 14, and the cleaning assembly 3 comprises an air outlet a7 and an air outlet b14 arranged on the conveyor belt 1. The cleaning cylinder 10 on the side of the belt 1 and the water tank 11 connected to the cleaning cylinder 10, drive the piston assembly a4 and the piston assembly b5 to perform piston movement during the conveying process of the conveyor belt 1, the piston assembly a4 moves to inject gas into the gas injection cylinder and compress it, and drives the gas injection cylinder to rotate at the same time, the gas injection cylinder rotates during the inflation process and after separating from the surface of the gas injection cylinder, the gas is ejected through the gas injection hole 13 and the gas injection hole 9 to perform air blowing cleaning on the conveyor belt, the cleaning assembly 3 includes a cleaning cylinder 10 arranged on the cleaning frame 6, and the piston assembly b5 performs piston movement while drawing water in the water tank 11 into the cleaning cylinder 10 and then spraying it onto the conveyor belt 1 for cleaning.

[0037] like Figure 3As shown, a rotating sleeve 21 is sleeved on the rotating shaft of the conveyor belt 1, a rotating shaft 22 is arranged on the side of the gas injection cylinder a8 and the gas injection cylinder b14, a belt is sleeved between the rotating shaft 22 and the rotating sleeve 21, a reciprocating thread segment a23 is arranged on the rotating shaft 22 of the gas injection cylinder a8, a reciprocating thread segment b26 is arranged on the rotating shaft 22 of the gas injection cylinder b14, the gas outlet a7 and the gas outlet b12 are meshingly arranged on the reciprocating thread segment a23, a slide cylinder 24 is arranged on the cleaning frame 6, a slide rod 25 is arranged on the side of the gas outlet a7 and the gas outlet b12, the slide rod 25 is slidably arranged in the slide cylinder 24, and the reciprocating thread segment a23 and the reciprocating thread segment b26 have opposite rotation directions.

[0038] It is worth mentioning that the reciprocating threaded section a23 can drive the gas outlet cylinder a7 and the gas outlet cylinder b12 to move left and right during the rotation of the gas injection cylinder 8, so that the gas injection hole 9 can inject gas over a wider range to avoid omission.

[0039] like Figure 3 , Figure 4 As shown, a motor 31 for driving the conveyor belt 1 is arranged on the side of the cleaning frame 6, the piston assembly a4 includes a piston cylinder a32 arranged below the conveyor belt 1 and a piston a33 slidably arranged in the piston cylinder a32, and a piston rod a34 is arranged on the end face of the piston a33. Conical teeth a35 and conical teeth b36 that mesh with each other are rotatably arranged on the cleaning frame 6, and a turntable a37 is arranged on the conical teeth b36. A hinged rod a38 is eccentrically hinged on the turntable a37, and one end of the hinged rod a38 is arranged to intersect with the piston rod a34.

[0040] It should be noted that while the motor 31 drives the conveyor belt 1 for conveying, it drives the conical gear a35 to rotate through the belt, the conical gear a35 drives the conical gear b36 to rotate, and the conical gear b36 drives the turntable a37 to rotate. The turntable a37 drives the piston a33 to move through the hinged rod a38 to inject gas into the gas injection cylinder a7. At the same time, the gas injection cylinder a8 rotates under the drive of the rotating sleeve 21. When the injection hole on the gas injection cylinder a8 and the injection hole 9 on the gas outlet cylinder a7 coincide with each other, the gas in the gas injection cylinder is ejected to blow and clean the feces on the conveyor belt 1. By compressing the air first and then releasing it, the cleaning effect of the air blowing is greatly improved.

[0041] like Figure 5As shown, the piston assembly b5 includes a turntable b41 rotatably arranged on the cleaning frame 6, a belt is provided between the turntable b41 and the conical gear a35, a piston cylinder b42 is provided on the cleaning frame 6, a piston b43 and a piston rod b44 arranged on the piston b43 are slidably arranged in the piston cylinder b42, a hinged rod b45 is hingedly arranged on the piston rod b44, one end of the hinged rod b45 is hingedly arranged with the piston rod b44, one end of the hinged rod b45 is eccentrically hinged to the surface of the turntable b41, and a plurality of water spray holes 46 are provided on the surface of the cleaning cylinder 10.

[0042] It is explained here that when the conical tooth a35 rotates, the turntable b41 is driven to rotate through the belt. The rotation of the turntable b41 drives the piston b43 to move back and forth through the hinge rod b45, so that the water in the water tank 11 is pumped into the cleaning cylinder 10 and then sprayed out from the water spray hole 46 through the piston b43 to spray water on the conveyor belt 1, so as to moisten the feces on the conveyor belt 1 to prevent it from sticking too firmly and being unable to be blown away by air.

[0043] like Figure 8 As shown, the air injection holes 9 on the air outlet cylinder a7 and the air outlet cylinder b12 are inclined at 30-45 degrees to the conveying direction of the conveyor belt 1.

[0044] It is worth mentioning here that by tilting the air jet holes 9 on the air jet a7 and the air jet b12 by 30-45 degrees to the conveying direction of the conveyor belt 1, the air blown out of the air jet holes 9 can blow the feces on the conveyor belt 1 toward the ground, preventing the feces from remaining on the conveyor belt 1 after being blown.

[0045] like Figure 4 As shown, the piston cylinder a32 is connected to the gas injection cylinder via a water pipe a61, and the water pipe a61 is made of stainless steel and is arranged on the cleaning frame 6.

[0046] In addition, by making the water pipe a61 of stainless steel and arranging it on the cleaning rack 6, the air injection cylinder can also be fixed by the water pipe a61 to prevent the air injection cylinder from moving during the air blowing process.

[0047] like Figure 6 As shown, a through groove 71 is provided in the gas outlet tube and the gas outlet tube, and the width of the through groove 71 is equal to the diameter of the gas injection hole 13.

[0048] It should be mentioned here that by providing the through groove 71 , the gas ejected from the gas injection hole 13 can be transferred to the gas injection hole 9 through the through groove 71 and then ejected through the gas injection hole 9 .

[0049] like Figure 5As shown, a water pipe b81 is provided between the water tank 11 and the cleaning cylinder 10, a water pipe c82 is provided between the cleaning cylinder 10 and the piston cylinder b42, and a one-way valve is provided on the water pipe b81.

[0050] In addition, the one-way valve of the water pipe b81 is configured so that water can only flow from the water tank 11 to the cleaning cylinder 10, thereby preventing the piston b43 from moving and causing the water to flow back into the water tank 11 when the cleaning cylinder 10 sprays water.

[0051] like Figure 8 As shown, the conveyor belt 1 is installed with a support plate 91 , and a scraper 92 is arranged at the lower end of the support plate 91 , and the scraper 92 is arranged to fit the surface of the conveyor belt 1 .

[0052] A check valve is disposed on each of the water spray holes 46 .

[0053] It is worth mentioning here that the one-way valve of the water spray hole 46 is set so that water vapor can only flow from the inside of the cleaning tube 10 to the outside, preventing the piston b43 from pumping air from the outside while pumping water, resulting in insufficient water extraction and affecting the cleaning effect.

[0054] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "front and back", "left and right", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the invention.

[0056] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art under the technical prompts of the present invention should be included in the protection scope of the present invention.
