Description

Technical Field

[0001] The invention relates to the technical field of ground film processing structures, in particular to ground film cotton stalk crushing and sorting equipment. Background Art

[0002] In cotton-growing areas, farmland waste disposal often faces the problem of mixing of ground film (agricultural plastic film) and cotton stalks (cotton straw). This mixing is mostly caused by incomplete mechanized harvesting or inadequate manual cleaning.

[0003] The key challenges in achieving efficient co-crushing of both plastic and plant materials lie in the following: First, mulch film is lightweight, soft, and easily tangled, which can clog traditional pulverizing equipment. Second, cotton stalks are rich in fiber, strong, and resilient, requiring high shear or impact power for pulverization. Therefore, pulverizing equipment must be capable of both shearing and shredding plastic film and efficiently pulverizing plant fibers, while minimizing clogging.

[0004] Therefore, there is an urgent need in this field to provide a mulch film and cotton stalk crushing and sorting equipment that can efficiently crush mulch film and cotton stalks and reduce the occurrence of blockage. Summary of the Invention

[0005] The purpose of the present invention is to provide a mulch film and cotton stalk crushing and sorting device, which can crush mulch film and cotton stalks efficiently and reduce the occurrence of blockage.

[0006] To achieve the above-mentioned object, the present invention provides a mulch film cotton stalk crushing and sorting device, comprising a mulch film cotton stalk crusher and a mulch film sorting machine, wherein the mulch film cotton stalk crusher and the mulch film sorting machine are connected together through a discharge hopper, and the material is crushed by the mulch film cotton stalk crusher and then enters the mulch film sorting machine for sorting mulch film and impurities; The mulch and cotton stalk crusher includes a main base, a drive assembly, a rotating shaft and a feed hopper. The material enters from the feed hopper. The drive assembly and the feed hopper are connected to the top of the main base. The rotating shaft is rotatably connected to the inside of the feed hopper. The drive assembly drives the rotating shaft to rotate. Cutters are connected to the rotating shaft and the two opposite inner walls of the feed hopper.

[0007] Preferably, the tool includes tool one, tool two and tool three, and several rows of tool one and several rows of tool two are connected circumferentially on the rotating shaft. The tool two is staggered between two rows of tool one, and the two opposite inner walls of the feed hopper are respectively connected with tool three, and the tool three is engaged with tool one and tool two.

[0008] Preferably, the tool 1 includes a first blade tooth and a second blade tooth, and a row of the first blade teeth and a row of the second blade teeth are axially arranged side by side at two edges of the outer peripheral wall of the rotating shaft.

[0009] Preferably, the second tool includes three teeth, a row of the three teeth is axially arranged in the middle of the outer peripheral wall of the rotating shaft, and the three teeth are staggered between the two rows of the first tool.

[0010] Preferably, the tool three includes four blade teeth, and several of the four blade teeth are arranged on two opposite inner walls of the feed hopper along the axial direction of the rotating shaft, and the four blade teeth are all engaged with the first blade tooth, the second blade tooth, and the third blade tooth.

[0011] Preferably, three rows of tool 1 and three rows of tool 2 are evenly arranged on the rotating shaft.

[0012] Preferably, the included angle between the tool 2 and the tool 1 in one adjacent row is 30°, and the included angle between the tool 2 and the tool 1 in another adjacent row is 90°.

[0013] Preferably, the tooth one, the tooth two and the tooth three are welded or bolted to the side of the trapezoidal plate, and several of the trapezoidal plates are evenly arranged on the rectangular plate. A groove is opened on the outer peripheral wall of the rotating shaft, and the rectangular plate is welded in the groove of the rotating shaft.

[0014] Preferably, the main base includes a base and an intermediate base, the intermediate base is connected to the top of the base, the top of the intermediate base is rotatably connected to a rotating shaft through a bearing, and the feed hopper is connected to the intermediate base.

[0015] Preferably, a drive assembly is connected to the base, and the drive assembly includes a motor, a belt, a pulley 1 and a pulley 2. The motor is installed on the base, the output shaft of the motor is connected to the pulley 1, and one end of the rotating shaft is connected to the pulley 2. The pulley 1 and the pulley 2 are connected together by a belt.

[0016] The advantages and positive effects of the mulch film cotton stalk crushing and sorting equipment described in the present invention are: 1. The three blade teeth are staggered between the two rows of blade teeth. This staggered arrangement allows the material to be cut again by the middle blade tooth three after being cut by the edge blade teeth one and two, which helps to cut the material more evenly and delicately, thereby improving the processing quality of the material.

[0017] 2. Tooth 4 meshes with teeth 1, 2 and 3 to form a shearing effect, which can cut the material more effectively, avoid incomplete or uneven cutting of the material, and improve cutting accuracy and efficiency.

[0018] 3. Due to the staggered arrangement of the blade teeth, the material is continuously dispersed and redistributed during the cutting process, avoiding excessive accumulation of material in a certain area, which helps to maintain the continuous flow of the material. For some strip-shaped materials, the staggered blade teeth will constantly interact with each other during the operation of the equipment, helping to clean the residue from the inner wall of the equipment and the surface of the blade teeth, reducing the chance of material entanglement on the blade.

[0019] 4. The mulch film and cotton stalk crusher has a significant and efficient processing capacity. It can crush about 200 tons of mulch film and cotton stalk mixture every day, effectively meeting the needs of large-scale farmland waste treatment.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] In this application, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. In the event of any inconsistency, the meaning described in this specification or the meaning derived from the contents recorded in this specification shall prevail. In addition, the terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0025] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-10 As shown, a mulch film and cotton stalk crushing and sorting device includes a mulch film and cotton stalk crusher and a mulch film sorting machine 9, which are connected together through a discharge hopper 10. After being crushed by the mulch film and cotton stalk crusher, the material enters the mulch film sorting machine 9 for sorting mulch film and impurities.

[0027] Specifically, such as Figure 9 、 Figure 10 As shown, the ground film sorting machine 9 includes a ground film conveying assembly, an impurity conveying assembly, and a power drive assembly. The ground film conveying assembly includes a ground film conveying roller 12 and a ground film conveying housing 13. The ground film conveying roller 12 is driven by the power drive assembly and is rotatably connected to the inside of the ground film conveying housing 13. The outer peripheral wall of the ground film conveying roller 12 is provided with spiral teeth 19. A filter screen 14 is connected to the bottom of the ground film conveying housing 13. The impurity conveying assembly includes an auger 11 and an auger housing 15. The auger 11 is driven by the power drive assembly and is rotatably connected to the inside of the auger housing 15, and the auger 11 is located below the filter screen 14. A protective cover 18 connects the ground film conveying housing 13 and the auger housing 15.

[0028] The operating principle of the mulch film sorting machine 9 is as follows: the material to be sorted enters the mulch film conveying housing 13 and the mulch film conveying roller 12 of the mulch film sorting machine 9 from the discharge hopper 10. Due to the different masses of mulch film and other impurities, such as straw, the mulch film and impurities initially move forward along the channel formed by the mulch film conveying housing 13 and the mulch film conveying roller 12, driven by the high-speed rotation of the mulch film conveying roller 12 and the helical teeth 19. When the mulch film reaches the filter 14, the heavier impurities, other than the mulch film, pass through the filter 14 due to centrifugal force and gravity. They are then restrained by the protective cover 18 and fall into the impurity conveying channel. The impurities are then driven forward by the auger 11 along the channel formed by the auger housing 15 and are ultimately discharged through the impurity outlet 16. The lighter mulch film continues to move forward along the mulch film conveying channel and is ultimately discharged through the mulch film outlet 17, completing the separation of the mulch film and impurities.

[0029] The mulch and cotton stalk shredder includes a main base 1, a drive assembly 2, a rotating shaft 3, and a feed hopper 8. Material enters the feed hopper 8. The drive assembly 2 and the feed hopper 8 are connected to the top of the main base 1. The rotating shaft 3 is rotatably connected to the inside of the feed hopper 8. The drive assembly 2 drives the rotating shaft 3 to rotate. Cutters are attached to the rotating shaft 3 and to the two opposing inner walls of the feed hopper 8.

[0030] The cutting tools include Cutters 1, 2, and 3. Several rows of Cutters 1 and 2 are circumferentially connected to the rotating shaft 3. Cutters 2 are staggered between the rows of Cutters 1. Cutters 3 are connected to the two opposing inner walls of the feed hopper 8, each meshing with Cutters 1 and 2.

[0031] like Figure 2-Figure 4 As shown, specifically, six blade teeth 1 4 form a row, six blade teeth 2 5 form a row, and six blade teeth 3 6 form a row.

[0032] The tool 1 includes a blade tooth 4 and a blade tooth 2 5 . A row of blade teeth 1 4 and a row of blade teeth 2 5 are arranged side by side at two edges of the outer peripheral wall of the rotating shaft 3 along the axial direction.

[0033] The second tool includes three blade teeth 6. A row of three blade teeth 6 is axially arranged in the middle of the outer peripheral wall of the rotating shaft 3. The three blade teeth 6 are staggered between the two rows of the first tool.

[0034] The cutter three includes four teeth 7, and several four teeth 7 are arranged on two opposite inner walls of the feed hopper 8 along the axial direction of the rotating shaft 3, and the four teeth 7 are all engaged with the first tooth 4, the second tooth 5, and the third tooth 6.

[0035] like Figure 3 As shown, specifically, fifteen blade teeth 7 are evenly arranged on both side walls of the feed hopper 8.

[0036] Three rows of tool 1 and three rows of tool 2 are evenly arranged on the rotating shaft 3.

[0037] The included angle between Cutter 2 and one of the adjacent rows of Cutter 1 is 30°, and the included angle between Cutter 2 and the other adjacent row of Cutter 1 is 90°. The 30° angle setting allows Cutter 2 to penetrate the material more smoothly, reducing resistance during cutting. The 90° vertical setting provides strong vertical shear force, enabling more thorough cutting of the material. The combination of 30° and 90° settings allows the material to be cut multiple times at different angles, thereby improving the uniformity of the crushing.

[0038] Teeth 1 (4), 2 (5), and 3 (6) are welded or bolted to the sides of the trapezoidal plate. Several trapezoidal plates are evenly arranged on a rectangular plate. A groove is formed on the outer wall of the rotating shaft (3), and the rectangular plate is welded into the groove of the rotating shaft (3).

[0039] Specifically, the bottom of the trapezoidal plate is welded to the rectangular plate. A square groove is provided on the outer peripheral wall of the rotating shaft 3, and the square groove matches the specifications of the rectangular plate.

[0040] The main base 1 includes a base 101 and an intermediate base 102. The intermediate base 102 is connected to the top of the base 101. The top of the intermediate base 102 is rotatably connected to the rotating shaft 3 through a bearing, and the feed hopper 8 is connected to the intermediate base 102.

[0041] Specifically, the base 101 and the intermediate base 102 are connected by bolts, and the feed hopper 8 and the intermediate base 102 are connected by bolts.

[0042] Drive assembly 2 is connected to base 101 and includes a motor 201, a belt 202, a pulley 1 203, and a pulley 2 204. Motor 201 is mounted on base 101. The output shaft of motor 201 is connected to pulley 1 203. One end of rotating shaft 3 is connected to pulley 2 204. Pulleys 1 203 and 204 are connected together via belt 202.

[0043] Specifically, the motor 201 is started, and the output shaft of the motor 201 rotates to drive the pulley 1 203 to rotate. The pulley 1 203 rotates through the belt 202 to drive the pulley 2 204 to rotate. The pulley 2 204 rotates to drive the rotating shaft 3 to rotate. The rotating shaft 3 rotates to drive the tool 1 and the tool 2 to alternately engage with the tool 3, thereby crushing the material in the feed hopper 8.

[0044] The use process of the present invention is: First, pour the mixture of ground film and cotton stalks into the feed hopper 8.

[0045] Secondly, start the motor 201, and the output shaft of the motor 201 rotates to drive the pulley 1 203 to rotate. The rotation of the pulley 1 203 drives the pulley 2 204 to rotate through the belt 202. The rotation of the pulley 2 204 drives the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 drives the cutter 1 and the cutter 2 to alternately engage with the cutter 3, thereby crushing the ground film and cotton stalks in the feed hopper 8.

[0046] Finally, the crushed ground film and cotton stalks are output from the feed hopper 8 to the discharge hopper 10, and enter the ground film sorting machine 9 from the discharge hopper 10 to be sorted from the ground film and impurities.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solutions of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
