Description

Technical Field

[0001] The utility model relates to the technical field of cattle breeding, and particularly relates to a forage shredder for cattle breeding. Background Art

[0002] With the large-scale development of agricultural mechanization and breeding industry, forage shredders are widely used. Green plants are essential in cattle breeding. To facilitate the cattle's feeding, green plants are usually put into the forage shredder for processing. The forage shredder can shred various straws, grasses, and green vines into filaments, reducing the volume of straws, grasses, and green vines, facilitating storage, and avoiding the phenomenon of straws, grasses, and green vines caking due to the rapid extrusion of water in them. The straws, grasses, and green vines shredded into filaments by the forage shredder can be directly eaten by livestock or piled up for fermentation.

[0003] In the prior art, when the conventional forage shredder discharges materials, the materials will be ejected from the discharge port along with the high-speed flowing air. Since the processed materials are relatively light, they are prone to splash towards the discharge port during ejection. The fine powder in the materials is scattered in the air, which is likely to affect the surrounding environment. At the same time, the splashing materials are not conducive to centralized collection. How to invent a forage shredder for cattle breeding to improve these problems has become an urgent problem for those skilled in the art. Summary of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides a forage shredder for cattle breeding, aiming to improve the problem that when the conventional forage shredder discharges materials, the materials are ejected from the discharge port, which is likely to affect the surrounding environment and is not conducive to centralized collection.

[0005] The utility model is implemented as follows:

[0006] The utility model provides a forage shredder for cattle breeding, which includes a machine body and a discharge pipe arranged on the machine body. The discharge pipe is installed on the outer wall of the discharge port of the machine body. One end of the discharge pipe is communicated with a blanking pipe. An upper installation groove is opened above the discharge pipe, and an upper filter screen is installed on the inner wall of the upper installation groove. A side installation groove is opened at one end of the discharge pipe, and a side filter screen is installed on the inner wall of the side installation groove.

[0007] Preferably, the upper filter screen is fixed to the upper installation groove by installing guiding bolts. The inner wall of the upper filter screen is slidably connected to the outer wall of the guiding bolts. The side installation groove is tightly fixed to the side filter screen by bolts.

[0008] By adopting the above technical scheme, the processed material in the machine body is ejected into the discharge pipe through the discharge port, and the high-speed ejected air carries the material and hits the side wall of the discharge pipe. The air in the material is filtered by the upper filter and the side filter. After the material hits the inner wall of the discharge pipe, it is discharged and collected through the lower pipe under the action of gravity, preventing the material from being ejected and being unfavorable for collection.

[0009] Preferably, the inner wall of the discharge pipe is rotatably connected to an adjusting shaft, a plurality of blades are installed on the outer wall of the adjusting shaft, the interior of the blades is hollow in design, and one end of the adjusting shaft is fixedly connected to a first pulley.

[0010] Preferably, a telescopic rod is fixedly connected to the bottom end of the upper filter screen, and an adjusting ball slidably connected to the blade is fixedly connected to one end of the telescopic rod.

[0011] Preferably, the inner wall of the discharge pipe is rotatably connected to a reciprocating screw rod, and the lower inner wall of the discharge pipe close to the reciprocating screw rod is fixedly connected to a guide rod.

[0012] Preferably, a scraper is slidably connected to the outer wall of the guide rod, the inner wall of the scraper is threadedly connected to the outer wall of the reciprocating screw rod, and a brush is fixedly connected to one side of the scraper.

[0013] Preferably, one end of the reciprocating screw is fixedly connected to a second pulley, and a belt drivingly connected to the first pulley is installed on the second pulley.

[0014] By adopting the above technical scheme, the sprayed material is buffered by the arranged adjusting shaft and the blades, and at the same time, the flowing air blows the blades to drive the adjusting shaft to rotate. While the adjusting shaft rotates, one end thereof drives the scraper on the side filter plate to reciprocate with the cooperation of the belt, and the filter net is cleaned by the brush. At the same time, when rotating, the blade presses against the adjusting ball to squeeze the telescopic rod to drive the upper filter net to move upward. When the blade is detached, it falls down under the action of gravity and collides with the inner wall of the upper mounting groove to vibrate, so as to clean the material adhering to the upper filter net.

[0015] The beneficial effects of the utility model are:

[0016] By means of the arranged blade and the adjusting shaft, the kinetic energy of the ejected material is converted into mechanical energy, reducing the flow rate of the material to avoid the material splashing out of the machine body. At the same time, the two arranged filter meshes filter the high-speed flowing air, causing the material to impact on the inner wall of the discharge pipe and collecting the material under the action of gravity. Meanwhile, the arranged adjusting ball and the blade cause the upper filter plate to vibrate up and down continuously while the blade rotates, cleaning the material adhered to the filter mesh. At the same time, the scraper cooperates with the reciprocating lead screw to drive the scraper to slide while the adjusting shaft rotates, so that the brush on one side of the scraper cleans the outer wall of the side filter plate, improving the filtering effect of this filter mesh, so that the material can be discharged more smoothly through the blanking pipe.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Example, refer to Figures 1 - 4 , a forage chopper for cattle breeding, including a machine body 1 and a discharge pipe 2 arranged on the machine body 1. The discharge pipe 2 is installed on the outer wall of the discharge port of the machine body 1. One end of the discharge pipe 2 is communicated with a feeding pipe 19. An upper installation groove 3 is opened above the discharge pipe 2. An upper filter screen 4 is installed on the inner wall of the upper installation groove 3. A side installation groove 11 is opened at one end of the discharge pipe 2. A side filter screen 12 is installed on the inner wall of the side installation groove 11.

[0025] Furthermore; the upper filter screen 4 is fixed to the upper installation groove 3 by installing a guiding bolt 7. The inner wall of the upper filter screen 4 is slidably connected to the outer wall of the guiding bolt 7. The side installation groove 11 is tightly fixed to the side filter screen 12 by bolts.

[0026] It should be noted that: the processed materials in the machine body 1 are ejected through the discharge port into the discharge pipe 2. The high-speed ejected air carries the materials and impacts on the side wall of the discharge pipe 2. The air in the materials is filtered by the upper filter screen 4 and the side filter screen 12. After the materials impact on the inner wall of the discharge pipe 2, they are discharged and collected through the feeding pipe 19 under the action of gravity, preventing the materials from being ejected and being unfavorable for collection.

[0027] Furthermore; a regulating shaft 8 is rotatably connected to the inner wall of the discharge pipe 2. A plurality of blades 9 are installed on the outer wall of the regulating shaft 8. The inside of the blades 9 is hollow-designed. One end of the regulating shaft 8 is fixedly connected to a first pulley 10. The bottom end of the upper filter screen 4 is fixedly connected to a telescopic rod 5. One end of the telescopic rod 5 is fixedly connected to an adjusting ball 6 that is slidably connected to the blades 9. A reciprocating lead screw 14 is rotatably connected to the inner wall of the discharge pipe 2. A guiding rod 13 is fixedly connected to the inner wall of the discharge pipe 2 near the lower part of the reciprocating lead screw 14. A scraping plate 17 is slidably connected to the outer wall of the guiding rod 13. The inner wall of the scraping plate 17 is threadedly connected to the outer wall of the reciprocating lead screw 14. A brush 18 is fixedly connected to one side of the scraping plate 17. One end of the reciprocating lead screw 14 is fixedly connected to a second pulley 15. A belt 16 that is drivingly connected to the first pulley 10 is installed on the second pulley 15.

[0028] It should be noted that the ejected material is buffered by the adjusting shaft 8 and the blades 9. At the same time, the flowing air blows the blades 9 to rotate the adjusting shaft 8. While the adjusting shaft 8 is rotating, the first pulley 10 at one end thereof cooperates with the belt 16 to drive the second pulley 15 to drive the reciprocating lead screw 14 to rotate. The reciprocating lead screw 14 drives the scraper 17 to slide reciprocally on the guide rod 13. During the sliding process, the brush 18 provided at one end thereof scrapes the material on the side filter net 12 to prevent it from being blocked. At the same time, when the blade 9 rotates, it presses against the adjusting ball 6 to squeeze the telescopic rod 5 to drive the upper filter net 4 to move upward. When the blade 9 disengages, it falls under the action of gravity and collides with the inner wall of the upper mounting groove 3 to vibrate, and the material adhered to the upper filter net 4 is vibrated and sieved to prevent the upper filter net 4 from being blocked.

[0029] The working principle of this cattle breeding forage chopper:

[0030] The processed material in the machine body 1 is ejected through the discharge port and enters the discharge pipe 2. The high-speed ejected air carries the material and blows the blade 9 to rotate the adjusting shaft 8. While the adjusting shaft 8 is rotating, the first pulley 10 at one end thereof cooperates with the belt 16 to drive the second pulley 15 to drive the reciprocating lead screw 14 to rotate. The reciprocating lead screw 14 drives the scraper 17 to slide reciprocally on the guide rod 13. During the sliding process, the brush 18 provided at one end thereof scrapes the material on the side filter net 12 to prevent it from being blocked. At the same time, when the blade 9 rotates, it presses against the adjusting ball 6 to squeeze the telescopic rod 5 to drive the upper filter net 4 to move upward. When the blade 9 disengages, it falls under the action of gravity and collides with the inner wall of the upper mounting groove 3 to vibrate, and the material adhered to the upper filter net 4 is vibrated and sieved to prevent the upper filter net 4 from being blocked. The air in the material is filtered by the upper filter net 4 and the side filter net 12. The material after sieving the air impacts on the inner wall of the discharge pipe 2, and then is discharged and collected through the blanking pipe 19 under the action of gravity, preventing the material from being ejected with air and affecting the surrounding environment, and facilitating the collection of the material.

[0031] It should be noted that the specific model and specification of the motor need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0032] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
