Description

Technical Field

[0001] This utility model relates to the technical field of feed grinding, specifically a forage grinding device. Background Technology

[0002] Animal husbandry is a production sector that utilizes the physiological functions of domesticated animals such as livestock and poultry, or wild animals such as deer, musk deer, foxes, minks, otters, and quails, through artificial breeding and raising to convert plant energy from pasture and feed into animal energy, producing livestock products such as meat, eggs, milk, wool, cashmere, hides, silk, and medicinal materials. Distinguished from subsistence livestock farming, animal husbandry is characterized by centralization, large-scale production, and a profit-driven objective. It is a crucial link in the exchange of resources between humans and nature. Currently, the feeding and processing of pasture and feed requires the use of crushing devices to break down the forage for better utilization.

[0003] Utility model patent CN220776605U discloses a forage crushing device, belonging to the field of feed crushing technology. It addresses the problem in existing technologies where forage crushing is limited to single-pass crushing, with the forage being fed into the crushing device, crushed once, and then discharged. While this method achieves crushing, a significant amount of incompletely crushed forage remains, leading to forage accumulation and blockage during subsequent feeding and processing, affecting future use. The device includes a base, a slidably connected pedestal, a fixedly connected housing, a crushing mechanism fixedly connected to the upper side of the housing, a screen fixedly connected to the middle of the housing, a discharge plate fixedly connected to the bottom of the housing, a feeding mechanism fixedly connected to the rear of the housing, an inclined plate fixedly connected to the top of the housing, and a baffle fixedly connected to the rear of the housing. The inclined plate and the baffle are aligned, and the feeding mechanism is slidably connected to one side of the baffle. This utility model utilizes the coordinated structure of a motor, a threaded rod, a conveying hopper, and a spring to transport oversized hay after crushing, allowing it to re-enter the top of the box for further crushing by the crushing mechanism. This improves the crushing effect and reduces the occurrence of oversized hay.

[0004] However, the above patent still has shortcomings: although the patent improves the crushing effect of forage, it does not have the function of regulating the internal moisture of forage. As a result, when feeding cattle, if the internal moisture of the forage is too low, it will affect the taste of the food. If the internal moisture of the forage is too high, it will affect rumination and cause digestive diseases. Utility Model Content

[0009] Preferably, a submersible pump is fixedly connected inside the water storage tank, and a three-way pipe is fixedly connected to the output end of the submersible pump. Both ends of the three-way pipe away from the submersible pump pass through the water storage tank and the pulverizing tank and extend to the annular pipe. The three-way pipe is connected to the annular pipe, and eight nozzles are evenly fixedly connected to the bottom of the annular pipe.

[0010] Preferably, the separation mechanism includes: a discharge port at one end of the separation cylinder, the discharge port being fixedly connected to the fixed box; a second motor being fixedly connected to the end of the separation cylinder away from the discharge port; a rotating shaft being fixedly connected to the output end of the second motor; the rotating shaft extending through the separation cylinder to a splined shaft at the end away from the second motor; the splined shaft being fixedly connected to the rotating shaft; a screw being fixedly connected to the end of the splined shaft away from the rotating shaft; a fixed frame being rotatably connected to the end of the screw away from the splined shaft; and the fixed frame being fixedly connected to the fixed box.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 6 The present invention will describe the above technical solution in detail through the following embodiments:

[0027] A forage pulverizing device includes: a water storage tank 1; a fixed box 2 is fixedly connected to the top of the water storage tank 1, a separating cylinder 3 is fixedly connected inside the fixed box 2, a pulverizing box 4 is fixedly connected to the top of the fixed box 2, and an inlet 5 is provided at the bottom of the pulverizing box 4. The bottom end of the inlet 5 passes through the fixed box 2 and extends to the separating cylinder 3. The inlet 5 is fixedly connected to the fixed box 2 and the separating cylinder 3. A pulverizing mechanism 6 with replaceable blades is provided inside the pulverizing box 4. A separating mechanism 7 for regulating the internal moisture of the pulverized forage is provided inside the separating cylinder 3. The user pours the forage into the pulverizing box 4, and then the pulverizing mechanism 6 pulverizes the forage while spraying water into the pulverizing box 4. The water flow carries the pulverized forage through the inlet 5 into the separating cylinder 3. Then, the separating mechanism 7 conveys and compresses the forage, thereby achieving the purpose of regulating the internal moisture of the forage.

[0028] like Figures 2 to 4 As shown, the pulverizing mechanism 6 includes: a filter plate 8 fixedly connected inside the pulverizing chamber 4; a limiting pin 9 fixedly connected at the top center of the filter plate 8; a rotating column 10 sleeved on the outer surface of the limiting pin 9; three blades 11 alternately arranged on the outer surface of the rotating column 10; each blade 11 fixedly connected to the rotating column 10; and a hexagonal groove 12 formed at the top of the rotating column 10. A matching chamber cover 13 is provided on the top of the pulverizing chamber 4; a first motor 14 is fixedly connected at the top center of the chamber cover 13; the output end of the first motor 14 passes through the chamber cover 13 and extends to a hexagonal block 15; the hexagonal block 15 is fitted with the hexagonal groove 12; and handles 16 are provided on both sides of the first motor 14, each handle fixedly connected to the chamber cover 13. After opening the lid 13 with the handle 16 and pouring the hay into the crushing box 4, close the lid 13 on top of the crushing box 4. At the same time, insert the hexagonal block 15 into the hexagonal groove 12 inside the rotating column 10, start the first motor 14, and the output of the first motor 14 drives the hexagonal block 15. The hexagonal block 15 drives the rotating column 10 through the hexagonal groove 12. The rotating column 10 rotates with the help of the limiting pin 9. While rotating, the rotating column 10 drives the blade 11, which cuts and crushes the hay inside the crushing box 4. The crushed hay enters the separation cylinder 3 through the filter plate 8 and the feed port 5. When the user needs to replace the blade, the rotating column 10 can be pulled directly from the outer surface of the limiting pin 9.

[0029] like Figure 2 and Figure 6As shown, a submersible pump 17 is fixedly connected inside the water storage tank 1. A three-way pipe 18 is fixedly connected to the output end of the submersible pump 17. Both ends of the three-way pipe 18 away from the submersible pump 17 pass through the water storage tank 1 and the grinding box 4 and extend to the annular pipe 19. The three-way pipe 18 is connected to the annular pipe 19. Eight nozzles 20 are evenly fixedly connected to the bottom of the annular pipe 19. When the submersible pump 17 is started, the output end of the submersible pump 17 draws water from the water storage tank 1 and delivers the water to the inside of the annular pipe 19 through the three-way pipe 18. Finally, the nozzles 20 spray the water into the inside of the grinding box 4. The water flow continuously washes the hay inside the grinding box 4, and the water flow drives the shredded hay to flow to the bottom of the grinding box 4.

[0030] like Figure 2 and Figure 5As shown, the separation mechanism 7 includes: a discharge port 21 at one end of the separation cylinder 3, which is fixedly connected to the fixed box 2; a second motor 22 fixedly connected to the end of the separation cylinder 3 away from the discharge port 21; a rotating shaft 23 fixedly connected to the output end of the second motor 22; the end of the rotating shaft 23 away from the second motor 22 passing through the separation cylinder 3 and extending to a splined shaft 24; the splined shaft 24 fixedly connected to the rotating shaft 23; a screw 25 fixedly connected to the end of the splined shaft 24 away from the rotating shaft 23; and a screw 25 fixedly connected to the end of the screw 25 away from the splined shaft 24. A fixed frame 26 is rotatably connected to the fixed box 2; a matching auger blade 27 is fixedly connected to the outer surface of the rotating shaft 23 located inside the separating cylinder 3; a pressing plate 28 is sleeved on the outer surface of the splined shaft 24 near the discharge port 21; a spring 29 is provided on the side of the pressing plate 28 away from the discharge port 21; an adjusting block 30 is provided on the end of the spring 29 away from the pressing plate 28; the adjusting block 30 is threadedly connected to the screw 25; the second motor 22 is started, and the output end of the second motor 22 drives the rotating shaft 23. Rotating shaft 23 drives splined shaft 24, which in turn drives screw 25. Screw 25 rotates in conjunction with fixed frame 26. Simultaneously, rotating shaft 23 drives auger blades 27. As auger blades 27 rotate, they continuously push the forage inside separating cylinder 3 towards discharge port 21. During this movement, the forage is squeezed by extrusion plate 28, separating the water within the forage. The water flows through separating cylinder 3 into fixed box 2, while the forage continues to move towards discharge port 21. When the screw is moved to the discharge port 21, it pushes the extrusion plate 28 to slide on the surface of the spline shaft 24, so that the extrusion plate 28 separates from the discharge port 21. The hay is discharged to the outside of the device through the gap between the discharge port 21 and the extrusion plate 28. When the device stops running, the user can also rotate the adjustment block 30. The adjustment block 30 rotates on the surface of the screw 25 and moves horizontally. By adjusting the distance between the adjustment block 30 and the extrusion plate 28, the hardness of the spring 29 can be adjusted, thereby controlling the internal moisture of the hay.

[0031] like Figure 1 and Figure 2 As shown, a drain outlet 31 is provided at the bottom of the fixed box 2 on the side away from the fixed frame 26, and water inside the fixed box 2 can be discharged to the outside of the device through the drain outlet 31.

[0032] like Figure 1 As shown, a control box 32 with an internal touch screen is fixedly connected to one side of the fixed box 2, and universal wheels 33 with braking function are fixedly connected to the four corners of the bottom of the water tank 1. The control box 32 facilitates the user to operate the device, and the universal wheels 33 facilitate the user to move and fix the device.

[0033] like Figure 1As shown, a water inlet 34 is provided on one side of the top of the water storage tank 1, and users can add water to the inside of the water storage tank 1 through the water inlet 34.

[0034] Working principle: The user opens the lid 13 using the handle 16, pours the hay into the shredder 4, and then closes the lid 13 on top of the shredder 4. Simultaneously, the hexagonal block 15 is inserted into the hexagonal groove 12 inside the rotating column 10. The first motor 14 and the submersible pump 17 are then activated. The output of the first motor 14 drives the hexagonal block 15, which in turn drives the rotating column 10 via the hexagonal groove 12. The rotating column 10 rotates with the help of the limiting pin 9. As it rotates, the rotating column 10 drives the blades 11, which cut and shred the hay inside the shredder 4. The output of the submersible pump 17 draws water from the water tank 1. Water is then transported through the three-way pipe 18 to the inside of the annular pipe 19, and finally sprayed into the inside of the pulverizing chamber 4 by the nozzle 20. The water flow continuously washes the hay inside the pulverizing chamber 4, and the water flow also carries the pulverized hay to the bottom of the pulverizing chamber 4. The pulverized hay enters the inside of the separator 3 along with the water flow through the filter plate 8 and the feed inlet 5. Then, the second motor 22 is started. The output end of the second motor 22 drives the rotating shaft 23, the rotating shaft 23 drives the splined shaft 24, the splined shaft 24 drives the screw 25, and the screw 25 rotates with the cooperation of the fixing frame 26. While rotating, the rotating shaft 23 also drives the auger blades. 27. As the auger blades 27 rotate, they continuously push the hay inside the separator 3 towards the outlet 21. Simultaneously, the hay is squeezed by the extrusion plate 28, separating the water inside the hay. The water flows through the separator 3 into the fixed box 2, while the hay continues to move towards the outlet 21. As the hay reaches the outlet 21, it pushes the extrusion plate 28 to slide on the surface of the spline shaft 24, causing the extrusion plate 28 to separate from the outlet 21. The hay is then discharged through the gap between the outlet 21 and the extrusion plate 28 to the outside of the device. Users can also discharge the hay when the device stops operating. The rotating adjusting block 30 rotates on the surface of the screw 25 while moving horizontally. By adjusting the distance between the adjusting block 30 and the extrusion plate 28, the hardness of the spring 29 can be adjusted, thereby controlling the internal moisture of the forage. The moisture content of the crushed forage can be controlled according to the growth cycle of cattle. This solves the problem that although existing forage crushing devices improve the crushing effect of forage, they do not have the function of controlling the internal moisture of the forage. As a result, when feeding cattle, if the internal moisture of the forage is too low, it will affect the taste. If the internal moisture of the forage is too high, it will affect rumination and cause digestive diseases.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
