Technical Field
[0001] The utility model relates to the technical field of straw processing, in particular to a straw cutting device for processing agricultural products. Background Art
[0002] Straw is the general term for the stems, leaves, and spikes of mature crops. It is a multi-purpose renewable biological resource. It is very necessary to recycle and reuse straw, so it is necessary to process the straw for recycling and reuse. Due to the long length and large volume of straw, it must first be cut and crushed before subsequent processing.
[0003] In the prior art, most cutting devices only have rotating blades to cut and crush the straw. Since the blades have limited contact with the straw, the cutting is not thorough and the straw can only be simply cut. Since the juice in the straw can be used as nutrients and fertilizers for crops, if the straw cannot be squeezed, not only will the juice in the straw be poorly utilized, but the existing cutting device will also have a relatively simple functionality. Utility Model Content
[0004] In view of the deficiencies of the existing technology, the utility model provides a straw cutting device for agricultural product processing to solve the problems of thorough straw cutting and single functionality of the cutting device.

DETAILED DESCRIPTION
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0024] See also Figure 1-5 The utility model provides a technical solution: a straw cutting device for agricultural product processing, comprising a cutting barrel 1 and a processing box 2 with an opening at the right end, the processing box 2 being connected to the lower end of the cutting barrel 1, the upper end of the cutting barrel 1 being connected to a feed hopper 3, a concave frame 4 being provided in the middle of the feed hopper 3, a driving motor 5 being fixed in the concave frame 4, a driving shaft 7 extending into the cutting barrel 1 being connected to the power end of the dynamic motor 5, a plurality of moving blades 8 being fixed to the periphery of the driving shaft 7, a plurality of fixed blades 9 being fixed to the inner wall of the cutting barrel 1, the moving blades 8 and the fixed blades 9 being alternately distributed up and down.
[0025] When the cutting device is used to cut straw, the straw is added into the cutting barrel 1 through the feed hopper 3, and the drive shaft 7 and the movable blade 8 are driven to rotate by the operation of the drive motor 5. Since the movable blade 8 and the fixed blade 9 are alternately distributed up and down, and the movable blade 8 and the fixed blade 9 are provided with multiple pieces, the cooperation of the movable blade 8 and the fixed blade 9 has a large cutting contact amount for the straw. Therefore, compared with the existing technology, it is conducive to more thorough cutting and crushing of the straw.
[0026] In this embodiment, at least three fixing rods 6 are fixed to the periphery of the concave frame 4 , and ends of the fixing rods 6 are fixed to the inner wall of the feed hopper 3 .
[0027] The concave frame 4 is fixed in the feed hopper 3 by the fixing rod 6. The fixing rod 6 has a small blocking range for the straw, so that the straw can be smoothly added into the cutting barrel 1 through the feed hopper 3 for cutting, and it is also beneficial to ensure the stable operation of the drive motor 5 in the concave frame 4.
[0028] In this embodiment, a pressing chamber 13 is opened at the right end of the processing box 2, and a baffle 15 is provided at the right end of the pressing chamber 13. A storage chamber 10 is opened at the left end of the processing box 2, and a pressing component is provided in the storage chamber 10. The pressing component includes a hydraulic cylinder 11 and a pressing plate 12. The hydraulic cylinder 11 is fixed in the storage chamber 10, and the pressing plate 12 is connected to the power end of the hydraulic cylinder 11. The lower end of the processing box 2 is connected to a liquid collecting hopper 14 communicated with the pressing chamber 13, and a filter plate 16 is installed at the connection between the liquid collecting hopper 14 and the pressing chamber 13. The lower end of the liquid collecting hopper 14 is connected to a drain valve 17.
[0029] After the straw is cut and crushed, it will fall into the processing box 2. If the straw needs to be squeezed, the pressing plate 12 will move to the right through the extension of the hydraulic cylinder 11. The pressing plate 12 will push the straw into the pressing chamber 13. The pressing plate 12 will press the straw against the side of the baffle 15 for squeezing. The juice produced by the squeezing is filtered through the filter plate 16 and collected in the liquid collecting hopper 14. The drain valve 17 can be opened to conveniently discharge the juice in the liquid collecting hopper 14 for use, so as to facilitate the application of fertilizer and nutrients to crops through the juice in the straw in the later stage.
[0030] In this embodiment, the baffle 15 slides through the top of the processing box 2, and a lifting plate 20 is fixed to the upper end of the baffle 15. A forward and reverse motor 18 is fixed to the right side of the feed hopper 3. The power end of the forward and reverse motor 18 is connected to a screw rod 19. The end of the screw rod 19 is rotatably connected to the upper end of the processing box 2. The lifting plate 20 is threadedly sleeved on the outer periphery of the screw rod 19. An inclined material guide plate 21 is fixed to the lower right end of the processing box 2.
[0031] When the squeezed straw needs to be discharged from the processing box 2, since the squeezed straw is in blocks, the forward and reverse motor 18 drives the screw rod 19 to rotate, and the screw rod 19 will drive the lifting plate 20 to move upward, so the lifting plate 20 will pull the baffle 15 upward until the blocks of straw can be discharged through the opening at the right end of the processing box 2. Therefore, the hydraulic cylinder 11 is extended to push the blocks of straw to the right, and the straw will be pushed out from the right end of the processing box 2, and finally slide down and unload along the inclined guide plate 21. The design of the guide plate 21 can prevent the straw from falling apart due to the large height difference when it falls, so that it can be collected and processed later. In summary, the functionality of the cutting device is effectively improved.
[0032] Working principle:
[0033] When straw is added into the cutting barrel 1 through the feed hopper 3, the drive shaft 7 and the movable blade 8 are rotated by the operation of the drive motor 5, and the movable blade 8 and the fixed blade 9 cooperate to cut and crush the straw. The cut straw will fall into the processing box 2, and the pressing plate 12 will move to the right through the extension of the hydraulic cylinder 11. The pressing plate 12 will push the straw into the pressing chamber 13 for pressing. The juice produced by pressing is filtered through the filter plate 16 and collected in the liquid collecting hopper 14.
[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
