Description
Technical Field
[0001] This invention relates to a manure return equipment, and more particularly to a cattle farm manure return and utilization device. Background Technology
[0002] A cattle farm manure reduction device is a specialized device for treating cattle farm manure and wastewater, converting it into useful resources. However, most manure reduction devices on the market use a single treatment method and operate in an open environment. The fertilization process cannot achieve environmental protection and efficiency, thus posing a certain impact on the environment. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide a device for returning cattle farm manure to the field, which can overcome the shortcomings of the existing technology and is beneficial to environmental protection and improve fertilization efficiency.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows.
[0005] A device for returning cattle farm manure to the field includes an inlet connected to a conveying mechanism. An auger is installed inside the conveying mechanism. One end of the conveying mechanism is connected to a compression flange, which is pressed tightly by a compression top plate, forming a compression seam. The compression top plate is slidably fitted onto a fixed bend pipe, and a compression spring is fitted onto the fixed bend pipe. One end of the compression spring is fixedly connected to a spring top plate, and the other end of the compression spring is connected to the compression top plate. A conveying motor is installed at the other end of the conveying mechanism and connected to the auger. The fixed bend pipe is fixed to a storage tank. The top of the storage tank is connected to the conveying mechanism via a guide pipe, and the bottom of the storage tank is connected to a manure application box. A metal shovel is installed in front of the manure application box, with one end extending to the soil inlet of the manure application box and axially connected to the bottom plate of the manure application box. The other end of the metal shovel extends below the ground surface. A support plate and front rollers are installed at the bottom of the conveying mechanism, and rear rollers are installed at the bottom of the manure application box. A soil outlet is installed at the rear of the manure application box.
[0006] Preferably, a four-way conduit is installed below the liquid storage tank, a pressure switch valve is installed at the inlet of the four-way conduit, two side spray columns are provided on each side of the four-way conduit, extending to both sides, and a vertical spray column is provided below the four-way conduit.
[0007] Preferably, a rotary crushing mechanism is provided below the vertical spray column. The rotary crushing mechanism includes two L-shaped support rods located on both sides of the vertical spray column. A tension spring is sleeved on the horizontal part of the L-shaped support rod. The extrusion plate is movably sleeved on the horizontal part of the L-shaped support rod and connected to the tension spring. An extrusion motor is installed on the inner wall of the manure application box. The extrusion motor is connected to an eccentric wheel through an eccentric connecting rod. The eccentric wheel periodically extrudes into contact with the extrusion plate. Extrusion cones are distributed on the inner surface of the extrusion plate. Two motor fixing rods are provided on the inner wall of the manure application box. A crushing motor is connected to the bottom of each motor fixing rod. The crushing motor is connected to a crushing fan blade. Weeding needles are fixed to the edge of the crushing fan blade. Crushing cones are distributed on the outer surface of the crushing fan blade. The crushing motor is located outside the extrusion plate. The center line connecting the two crushing motors is perpendicular to the center line connecting the two extrusion plates.
[0008] Preferably, the connection between the metal shovel and the bottom plate of the manure box is provided with several positioning holes, and the relative angle between the metal shovel and the bottom plate of the manure box is locked by inserting pins into the positioning holes.
[0009] The beneficial effects of adopting the above technical solution are as follows: This invention is equipped with a metal shovel. Depending on the type of vegetation covering the soil, the relative angle between the metal shovel and the bottom plate of the manure box can be adjusted by inserting a pin into the positioning hole to control the shovel's depth in the soil. This removes the roots of weeds and transports the soil containing weeds into the manure box, effectively removing weeds from the field and avoiding the incomplete weed removal or secondary rooting that often occurs with traditional methods. After solid-liquid separation at the top of the squeeze plate, the solid powder portion is recycled and reused. The fertilization process is carried out in a closed space. By spraying liquid fertilizer, volatilization is reduced, ensuring efficient utilization of the fertilization process. Because the fertilization process takes place in a closed space, it effectively reduces pollution of the surrounding air by the liquid fertilizer, protecting the environment and air quality. The pressure switch valve effectively controls the height of the liquid manure in the storage tank, ensuring that spraying is initiated under a certain pressure, guaranteeing the flow rate and spray range. The front and rear pulverizing fan blades are driven to rotate by their respective pulverizing motors, producing powder... The weeding needles between the crushed blades comb and separate the branches, leaves, and roots in the soil, leaving most of the weed roots on the needles, thus preventing weeds from returning to the field. The three crushing fan blades are arranged in a cone shape, leaving space for soil movement within the manure application box, creating a retention effect on more soil. The extrusion mechanism on both sides of the manure application box is driven by a motor and an eccentric wheel. These mechanisms form a semi-enclosed space with front-to-back stirring and side-to-side extrusion. The soil in this space is subjected to multiple actions of crushing, rolling, and extrusion, which promotes full separation and relative movement between soil particles, increasing the uniformity of fertilization. At the same time, it increases the soil's permeability and aeration, and extends the fertilization time. The extrusion plate also compresses the loose soil, bringing fertilized soil into pressure contact with unfertilized soil. Compared with the traditional method of natural liquid infiltration, this greatly improves fertilizer utilization. This helps to directly transport nutrients to the soil layer where the roots are located, improving nutrient utilization efficiency. Users can precisely control the type, amount, and depth of fertilizer application based on the needs of the crop and soil analysis results. This helps avoid problems such as over-fertilization and under-fertilization, and achieves precision fertilization. Attached Figure Description

[0016] Reference Figure 1-5 One specific embodiment of the present invention includes a feed inlet 1 connected to a conveying mechanism 5. An auger 3 is installed inside the conveying mechanism 5. One end of the conveying mechanism 5 is connected to a pressing flange 4, which is pressed tightly by a pressing top plate 6, forming a pressing seam 26. The pressing top plate 6 is slidably sleeved on a fixed bend 9, and a pressing spring 7 is sleeved on the fixed bend 9. One end of the pressing spring 7 is fixedly connected to a spring top plate 8, and the other end of the pressing spring 7 is connected to the pressing top plate 6. A conveying motor 2 is installed at the other end of the conveying mechanism 5. Machine 2 is connected to screw conveyor 3. Fixed bend pipe 9 is fixed on liquid storage tank 27. The top of liquid storage tank 27 is connected to conveying mechanism 5 through guide pipe 10. The bottom of liquid storage tank 27 is connected to manure box 29. A metal shovel 18 is provided in front of manure box 29. One end of metal shovel 18 extends to the soil inlet 28 of manure box and is axially connected to the bottom plate 22 of manure box. The other end of metal shovel 18 extends below the ground surface. The bottom of conveying mechanism 5 is provided with support plate 20 and front roller 19. The bottom of manure box 29 is provided with rear roller 17. The rear of manure box 29 is provided with soil outlet 16. This embodiment is equipped with a metal shovel 18. Depending on the different plants covering the soil, the relative angle between the metal shovel 18 and the bottom plate 22 of the manure box can be fixed by inserting a pin into the positioning hole 38. The depth of the metal shovel 18 into the soil can be adjusted to remove the roots of weeds. The soil containing weeds is transported to the manure box 29 by the metal shovel 18, which effectively removes weeds from the field and avoids the situation of incomplete weed removal or secondary rooting of weeds in traditional cultivated land.
[0017] A four-way conduit 14 is installed below the storage tank 27. A pressure switch valve 12 is installed at the inlet of the four-way conduit 14. Two side spray columns 11 are installed on each side of the four-way conduit 14, extending to both sides. A vertical spray column 13 is installed below the four-way conduit 14. The fertilization process is carried out in a closed space, which can effectively reduce the pollution of liquid fertilizer to the surrounding air, protect the environment and air quality. The pressure switch valve can effectively control the height of liquid manure in the storage tank, ensuring that the spraying is started under a certain pressure, and ensuring the flow rate and spraying range.
[0018] Additionally, a rotary tamping mechanism 15 is installed below the vertical spray column 13. The rotary tamping mechanism 15 includes two L-shaped support rods 35 located on both sides of the vertical spray column 13. A tension spring 34 is sleeved on the horizontal part of the L-shaped support rod 35. A squeezing plate 37 is movably sleeved on the horizontal part of the L-shaped support rod 35 and connected to the tension spring 34. A squeezing motor 36 is installed on the inner wall of the manure application box 29. The squeezing motor 36 is connected to an eccentric wheel 33 through an eccentric connecting rod 32. The eccentric wheel 33 periodically squeezes and contacts the squeezing plate 37. The inner surface of the squeezing plate 37... The manure distribution box 29 has two motor fixing rods 21 on its inner wall. Each motor fixing rod 21 has a crushing motor 25 connected to its bottom. The crushing motor 25 is connected to a crushing fan blade 24. Weeding needles 23 are fixed to the edge of the crushing fan blade 24. Crushing cones 30 are distributed on the outer surface of the crushing fan blade 24. The crushing motor 25 is located outside the extrusion plate 37. The center line connecting the two crushing motors 25 is perpendicular to the center line connecting the two extrusion plates 37. The two crushing fan blades 25 are driven to rotate by their respective crushing motors 25, crushing... The weeding needles 23 between the crushing blades 24 comb and separate the branches, leaves, and roots in the soil, leaving most of the weed roots on the needles 23, thus preventing the weeds from returning to the field. The three crushing blades 24 are arranged in a cone shape to allow space for soil movement within the manure application box 29, creating a retention effect on more soil. The extrusion plates 37 on both sides of the manure application box 29 are driven by the extrusion motor 36 and the eccentric wheel 33. The above mechanism forms a semi-enclosed space with front-to-back stirring and lateral extrusion, in which the soil is subjected to multiple actions of crushing, rolling, and extrusion. This process promotes thorough separation and relative movement between soil particles, increasing the uniformity of fertilization. Simultaneously, it enhances soil permeability and aeration, extending the time for fertilization. The pressing plate compresses the loose soil, creating pressure contact between fertile and unfertilized soil. Compared to traditional methods relying on natural liquid infiltration, this significantly improves fertilizer utilization. It facilitates direct nutrient delivery to the root zone, enhancing nutrient efficiency. Users can precisely control the type, amount, and depth of fertilizer application based on crop needs and soil analysis results. This helps avoid over-fertilization and under-fertilization, achieving precision fertilization.
[0019] Several positioning holes 38 are provided at the connection between the metal shovel 18 and the bottom plate 22 of the manure box. The relative angle between the metal shovel 18 and the bottom plate 22 of the manure box is locked by inserting pins into the positioning holes 38. The present invention is provided with a metal shovel 18, which can be used to fix the relative angle between the metal shovel 18 and the bottom plate 22 of the manure box by inserting pins into the positioning holes 38 according to different plants, and adjust the soil penetration depth of the metal shovel 18 to remove soil weed roots.
[0020] The working process of this invention is as follows: Cow manure is poured into the feed inlet 1. The built-in auger 3, driven by the conveyor motor 2, transports the cow manure to the extrusion flange 4 via the conveying mechanism 5. A through-hole (not shown in the figure) is provided at the front end of the extrusion flange 4. The through-hole is sealed by the extrusion top plate 6. The continuous thrust provided by the auger 3 increases the pressure at the extrusion flange 4. Under pressure, the extrusion top plate 6 is pushed open, and the dehydrated and dried cow manure is squeezed out from the through-hole and recycled through the pressure slit 26 (the pressure slit 26 has an external recycling mechanism, not shown in the figure). Simultaneously, liquid manure flows along the guide pipe 10 into the storage tank 27. The bottom of the storage tank 27 is controlled by a pressure switch valve 12, which is normally closed. When the liquid in the storage tank 27 accumulates to a certain height, the pressure switch valve is opened. Valve 12 allows liquid to flow into the four-channel pipe 14 under pressure and spray out from the vertical spray column 13 and side spray column 11 connected to it, completing the liquid fertilization operation. The equipment is driven forward by a power machine. The metal shovel 18 shovels soil with weeds and other plants into the manure box 29. The soil moves backward and passes through the rotary crushing mechanism 15. The rotating crushing blades 24 crush the clumps of soil with their edges, while the weeding needles 23 catch the stems, leaves and roots of the weeds under the action of rotation. The extrusion plates 37 set on both sides make a periodic inward extrusion movement under the action of the eccentric wheel 33, which extrudes the loose soil again, promotes the full mixing of liquid manure in the soil, and then crushes it a second time by the crushing blades 24 and discharges it from the manure box.
[0021] Because the crushing blades 24 are tilted relative to the rotating shaft of the crushing motor 25, the semi-enclosed space has a shape with a larger central area and smaller ends in the direction of the crushing blades 24. Simultaneously, the inwardly tilted end plates at both ends of the extrusion plate 37 also create a similar shape in the direction of the extrusion plate 37, resulting in a cyclical movement of soil within the semi-enclosed space from the edge inwards and then from the inside outwards. During this process, the crushing blades 24 rotate and agitate, while the extrusion plate 37 compresses the soil back and forth, allowing for localized flow of soil in different states during the circulation, achieving thorough mixing of the soil and liquid manure. Furthermore, the crushing cone 30 is located on the outer surface of the crushing blades 24 to pre-crush the soil outside the semi-enclosed space. Simultaneously, as the crushing blades 24 rotate, the crushing cone 30 pushes the lumpy soil that has just entered from the inlet 28 towards the side spray column 11, allowing for rapid contact and absorption of the lumpy soil with the liquid manure, thus accelerating the crushing effect of the lumpy soil.
[0022] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
