Description

Technical Field

[0001] This utility model relates to the field of feed cutting technology, and in particular to a multi-angle rotating blade type feed cutting device. Background Technology

[0002] In current technology, most straw cutting is done manually using a chaff cutter, which is not only inefficient but also poses safety hazards. Some factories use cutting devices to cut straw, but these devices usually cut the straw into small pieces rather than powder. During cutting, some straw is not completely chopped and falls off the cutting blade. At the same time, the cutting device cannot guarantee that all the small pieces are of uniform size, resulting in inconsistent particle sizes. If the chopped straw is not screened during this process, the larger pieces will be difficult for smaller livestock to eat, thus affecting subsequent use.

[0003] In the prior art, such as the feed cutting device described in Chinese Patent CN 221729007 U, a cutting box and a feeding hopper are included. An air supply component is installed at the upper end of the cutting box, and a storage box is installed at the lower end. A partition is installed at the upper end of the inner cavity of the cutting box, and a cutting component is installed in the middle of the inner cavity, located below the partition. A grid plate is installed between the cutting box and the storage box, and collection boxes are symmetrically installed on both sides of the storage box. The beneficial effect of this invention is that the grid plate at the lower end of the cutting box can limit the cutting of straw. When the chopped straw particles can pass through the grid plate, the fragments can fall into the storage box. At this time, the fragments can be filtered through a filter screen. Smaller fragments will fall through the filter screen, while larger fragments will slide to both sides and fall into the collection box through the channel and guide opening for collection. However, this patent also has the following problems.

[0004] In the aforementioned patent, although it can screen and collect straw feed of different particle sizes, when the type of feed to be cut changes, the cut size of different feeds may be different. However, the blade spacing between each group in the device is fixed, so it may be difficult to cut the feed into other specifications, thus reducing the scope of application. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology where the blade spacing between each group is fixed, making it difficult to cut feed into other specifications and reducing its application range. The proposed invention is a multi-angle rotating blade feed cutting device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a multi-angle rotating blade feed cutting device, comprising a housing, a motor fixedly installed on the outer wall of the housing, the output end of the motor entering the housing and fixedly installed on a rotating shaft, two symmetrically formed sliding grooves on the outer wall of the rotating shaft, multiple sets of evenly distributed connecting seats on the outside of the rotating shaft, two symmetrically installed fixing plates on the outer wall of the connecting seats, a first threaded hole penetrating through the top of the fixing plate, a connecting groove on the outer wall of the connecting seat, multiple evenly distributed multi-angle blades arranged inside the connecting groove, the multi-angle blades being connected to the connecting seats by bolts, a sliding plate fixedly installed on the inner wall of the connecting seat, a storage groove opened at one end of the sliding plate, a second threaded hole penetrating through the inner wall of the storage groove, a threaded rod threadedly connected inside the second threaded hole, a handle fixedly installed at one end of the threaded rod, and a fixing block movably connected to the end of the threaded rod away from the handle.

[0007] Preferably, the housing is provided with a grid plate inside, and the grid plate has slots on both outer sides.

[0008] Preferably, a limiting groove is formed on both sides of the inside of the housing, an electromagnet is fixedly installed on the inner wall of the limiting groove, and a plurality of evenly distributed second springs are fixedly installed on the outer wall of the electromagnet, with a locking block fixedly installed at one end of each of the plurality of second springs.

[0009] Preferably, limit plates are fixedly installed on both sides inside the housing.

[0010] Preferably, a control plate is fixedly installed on both sides inside the housing. Two first springs are fixedly installed on the top of the control plate. A connecting plate is fixedly installed on the top of the two first springs. A limit rod is fixedly installed on the bottom of the connecting plate. The bottom of the limit rod is slidably inserted into the control plate.

[0011] Preferably, the top of the connecting plate has a slot, the inner wall of the slot has a control groove, a third spring is fixedly installed on the inner wall of the control groove, a support block is fixedly installed on one end of the third spring, a connecting rod is fixedly installed on the end of the support block near the third spring, and a pull plate is fixedly installed on one end of the connecting rod through the connecting plate.

[0012] Preferably, a plate is slidably installed inside the slot, a support groove is provided on the outer wall of the plate, and a screen is fixedly installed on the top of the two plates.

[0013] Preferably, an electric telescopic rod is fixedly installed at the bottom of both control panels, and the telescopic end of the electric telescopic rod passes through the control panel and is fixedly installed with a push plate.

[0014] Preferably, a feed pipe is installed through and fixedly mounted on the top of the housing.

[0015] Preferably, a door is hinged to one end of the housing.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, during use, the operator places the corresponding number of connecting seats on the outer wall of the rotating shaft according to the requirements, the slide plate enters the slide groove, and then uses bolts to pass through the two first threaded holes to connect the two connecting seats together. Then, the multi-angle blades are inserted into the connecting groove and fixed to the connecting seats with bolts. Then, the distance between each group of multi-angle blades is adjusted. Finally, the operator rotates the handle, which drives the threaded rod to rotate, thereby causing the threaded rod to move along the second threaded hole. The fixing block contacts the inner wall of the slide groove, and the pressure exerted by the fixing block on the inner wall of the slide groove increases the friction between the two, thereby causing the connecting seats to be fixed. In this way, the distance between each group of multi-angle blades can be adjusted as needed.

[0018] 2. In this utility model, during replacement, the worker activates the electromagnet, causing the iron locking block to be attracted away from the slot, and the second spring is compressed. At this point, the worker can remove the grating plate and replace it with a grating plate of the corresponding specification. When the bottom of the limiting plate is in contact with the top of the grating plate, the worker closes the electromagnet, and the elastic force of the second spring pushes the locking block into the slot, thus fixing the grating plate. Then, the worker pulls two pull plates, which move the support block through the connecting rod, causing the support block to leave the support slot. The third spring is compressed, and the worker can then pull out the insert plate to replace the screen. The new screen is then reset, the insert plate is inserted into the slot, and the insert plate contacts the inclined surface of the support block. The insert plate pushes the support block to move, and the support block enters the control slot. The third spring is compressed, and when the support slot moves to the side of the support block, the elastic force of the third spring pushes the support block into the support slot, thus completing the replacement and improving the replacement efficiency.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1, such as Figures 1-7As shown, this utility model provides a multi-angle rotating blade type feed cutting device, including a housing 1. A motor 5 is fixedly installed on the outer wall of the housing 1. The output end of the motor 5 enters the housing 1 and is fixedly installed on a rotating shaft 12. Two sliding grooves 14 are symmetrically opened on the outer wall of the rotating shaft 12. Multiple sets of evenly distributed connecting seats 13 are arranged on the outside of the rotating shaft 12. Two fixing plates 17 are symmetrically installed on the outer wall of the connecting seats 13. A first threaded hole 18 is opened through the top of the fixing plate 17. A connecting groove 15 is opened on the outer wall of the connecting seat 13. Multiple evenly distributed multi-angle blades 16 are arranged inside the connecting groove 15.

A fixing block 24 is movably connected to the end of the threaded rod 22 away from the handle 23.

[0030] The effect achieved by the entire embodiment 1 is as follows: In use, the operator places the corresponding number of connecting seats 13 on the outer wall of the rotating shaft 12 as needed, the slide plate 19 enters the slide groove 14, and then uses bolts to pass through the two first threaded holes 18 to connect the two connecting seats 13 together. Then, the multi-angle blade 16 is inserted into the connecting groove 15 and fixed to the connecting seat 13 by bolts. Then, the distance between each group of multi-angle blades 16 is adjusted. Finally, the operator rotates the handle 23, which drives the threaded rod 22 to rotate, thereby causing the threaded rod 22 to move along the second threaded hole 21. The fixing block 24 contacts the inner wall of the slide groove 14, and the pressure exerted by the fixing block 24 on the inner wall of the slide groove 14 increases the friction between the two, thereby causing the connecting seat 13 to be fixed. In this way, the distance between each group of multi-angle blades 16 can be adjusted as needed.

[0031] Example 2, as Figures 1-7 As shown, further, a grid plate 4 is provided inside the housing 1, and slots 26 are provided on both sides of the outer side of the grid plate 4.

[0032] Furthermore, limit grooves 27 are provided on both sides of the inside of the housing 1. An electromagnet 28 is fixedly installed on the inner wall of the limit groove 27, and multiple evenly distributed second springs 29 are fixedly installed on the outer wall of the electromagnet 28. A locking block 30 is fixedly installed on one end of each of the multiple second springs 29.

[0033] Furthermore, limit plates 25 are fixedly installed on both sides inside the housing 1 to limit the grid plate 4.

[0034] Furthermore, control plates 6 are fixedly installed on both sides inside the housing 1. Two first springs 7 are fixedly installed on the top of the control plates 6. A connecting plate 8 is fixedly installed on the top of the two first springs 7. A limit rod 31 is fixedly installed on the bottom of the connecting plate 8. The bottom of the limit rod 31 is slidably inserted into the control plate 6.

[0035] Furthermore, a slot 32 is provided on the top of the connecting plate 8, and a control groove 33 is provided on the inner wall of the slot 32. A third spring 34 is fixedly installed on the inner wall of the control groove 33. A support block 35 is fixedly installed on one end of the third spring 34. A connecting rod 36 is fixedly installed on the end of the support block 35 near the third spring 34. One end of the connecting rod 36 passes through the connecting plate 8 and is fixedly installed with a pull plate 37.

[0036] Furthermore, a plate 38 is slidably installed inside the slot 32, and a support groove 39 is provided on the outer wall of the plate 38. A screen 9 is fixedly installed on the top of the two plates 38.

[0037] Furthermore, electric telescopic rods 10 are fixedly installed at the bottom of both control panels 6, and the telescopic ends of the electric telescopic rods 10 pass through the control panels 6 and are fixedly installed with push plates 11.

[0038] Furthermore, a feed pipe 3 is installed through and fixedly mounted on the top of the housing 1.

[0039] Furthermore, a door 2 is hinged to one end of the housing 1.

[0040] The overall effect of Embodiment 2 is as follows: During replacement, the operator activates the electromagnet 28, causing the iron locking block 30 to be attracted away from the slot 26, and the second spring 29 to be compressed. At this time, the operator can remove the grating plate 4 and replace it with a grating plate of the corresponding specification. When the bottom of the limiting plate 25 is in contact with the top of the grating plate 4, the operator closes the electromagnet 28, and the elastic force of the second spring 29 pushes the locking block 30 into the slot 26, at which point the grating plate 4 is fixed. Then, the operator pulls the two pull plates 37, and the pull plates 37 drive the support through the connecting rod 36. When the support block 35 moves away from the support groove 39, the third spring 34 is compressed, and then the operator can pull out the insert plate 38 to replace the screen 9. After that, the new screen 9 is reset, the insert plate 38 is inserted into the slot 32, and the insert plate 38 contacts the inclined surface of the support block 35. The insert plate 38 pushes the support block 35 to move, and the support block 35 enters the control groove 33. The third spring 34 is compressed, and when the support groove 39 moves to the side of the support block 35, the elastic force of the third spring 34 pushes the support block 35 into the support groove 39, thus completing the replacement and improving the replacement efficiency.

[0041] Working principle: In use, the operator places the corresponding number of connecting seats 13 on the outer wall of the rotating shaft 12 as needed, and the slide plate 19 enters the slide groove 14. Then, the two connecting seats 13 are connected together by bolts passing through the two first threaded holes 18. Then, the multi-angle blades 16 are inserted into the connecting groove 15 and fixed to the connecting seats 13 by bolts. Then, the distance between each set of multi-angle blades 16 is adjusted. Finally, the operator rotates the handle 23, which drives the threaded rod 22 to rotate, thereby causing the threaded rod 22 to move along the second threaded hole 21. The fixing block 24 contacts the inner wall of the slide groove 14. The pressure exerted by the fixing block 24 on the inner wall of the slide groove 14 increases the friction between the two, thereby fixing the connecting seats 13. In this way, the distance between each set of multi-angle blades 16 can be adjusted as needed. During replacement, the operator activates electromagnet 28, causing the iron locking block 30 to be attracted away from the slot 26, compressing the second spring 29. At this point, the operator can remove the grating plate 4 and replace it with a grating plate of the corresponding specification. When the bottom of the limiting plate 25 is in contact with the top of the grating plate 4, the operator deactivates electromagnet 28. The elastic force of the second spring 29 pushes the locking block 30 into the slot 26, thus fixing the grating plate 4 in place. Then, the operator pulls the two pull plates 37, which move the support block 35 via the connecting rod 36. When the support block 35 leaves the support groove 39, the third spring 34 is compressed, and then the operator can pull out the insert plate 38 to replace the screen 9. After that, the new screen 9 is reset, the insert plate 38 is inserted into the slot 32, and the insert plate 38 contacts the inclined surface of the support block 35. The insert plate 38 pushes the support block 35 to move, and the support block 35 enters the control groove 33. The third spring 34 is compressed, and when the support groove 39 moves to the side of the support block 35, the elastic force of the third spring 34 pushes the support block 35 into the support groove 39, thus completing the replacement and improving the replacement efficiency. In operation, the worker places the feed into the feed pipe 3, which falls onto the grid plate 4. The worker then starts the motor 5, causing the rotating shaft 12 to rotate. The multi-angle blades 16 begin cutting the feed, which falls onto the screen 9. The worker then activates the electric telescopic rod 10, which extends and pushes the push plate 11 upward. The push plate 11 then pushes the screen 9 upward, causing the first spring 7 to extend. When the telescopic rod 10 retracts, the spring force of the first spring 7 causes the screen 9 to descend, repeating this process to improve screening efficiency. Finally, the worker can open the door 2 to collect the feed.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
