Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, specifically relating to a straw bale netting removal machine. Background Technology

[0002] Straw is a general term for the stems and leaves (ears) of mature crops. The current method of straw processing is to collect it into bales and then send the bales into a straw cutter for processing. Before the bales of straw enter the straw cutter, the mesh packaging material on their surface needs to be removed.

[0003] The existing processing method is usually: first, the mesh packaging wrapped around the small square bundles of straw is cut off manually with a knife and then pulled out by hand, and then the straw is fed into the feeding system of the straw cutter; this processing method has low production efficiency and excessive labor intensity for workers. Summary of the Invention

[0004] The purpose of this invention is to provide a straw bale netting removal machine to solve the problems of existing manual netting removal in actual production, as mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a straw bale netting removal machine, comprising;

[0006] Support components are arranged along the conveying direction of the screen removal machine;

[0007] A conveying assembly, mounted on the support assembly, includes at least two conveying units arranged opposite each other in the width direction. Each conveying unit includes a contact portion arranged along the conveying direction, and the movement of the contact portion drives the material to move along the conveying direction.

[0008] A cutting assembly, mounted on the support assembly, includes an upper cutter and a lower cutter for forming cutting lines on the upper and lower surfaces of the mesh packaging material;

[0009] The netting assembly and the cutting assembly are arranged sequentially along the conveying direction. The netting assembly includes two netting mechanisms arranged opposite each other in the width direction. Each netting mechanism includes at least one netting hook that reciprocates along the netting path. When the netting hook moves to the approach point position, the net package contacts the tip of the netting hook and moves along the first path to the first turning point, after which it detaches from the tip.

[0010] Preferably, both the upper and lower cutters are circular saw blades that rotate around their own center. When the upper and lower cutters come into contact with the mesh packaging, they form a cutting point and, as the material moves in the conveying direction, form the cutting line.

[0011] Preferably, the support assembly includes a plate-shaped component extending in the conveying direction and the width direction, and a frame assembly supporting the plate-shaped component.

[0012] Preferably, the upper and lower cutting tools are spaced apart in the conveying direction.

[0014] Preferably, the net-removing mechanism further includes a housing component, the side wall of which is disposed around the periphery of the net-removing path. A first section of the side wall has an opening through which the tip of the net-removing hook passes. At least a portion of the second section of the side wall can surround the tip of the net-removing hook. When the tip of the net-removing hook moves to the second turning point position on the net-removing path, it enters the inner periphery of the housing component from the periphery of the housing component. The approach point, the first turning point, and the second turning point on the net-removing path are respectively located at the three vertices of the net-removing path. The net-removing mechanism further includes a support frame, and the bottom plate of the housing component is rotatably mounted on the support frame.

[0015] Preferably, the net-removing path is in the shape of an obtuse triangle.

[0016] Preferably, the net-removing mechanism further includes a chain, which is arranged along the net-removing path, and the wide end of the net-removing hook is mounted on the chain, so that the movement of the chain drives the movement of the net-removing hook.

[0017] Preferably, the conveying unit further includes a rotating part and a connecting part that connects the contact part and the two ends of the rotating part.

[0018] Preferably, the conveying assembly includes a first conveying unit, a second conveying unit, a third conveying unit, and a fourth conveying unit arranged opposite each other in the width direction. The third conveying unit and the fourth conveying unit are located inside the first conveying unit and the second conveying unit. The contact portion of the first conveying unit and the third conveying unit can cover the screen removal machine in the conveying direction in the first direction, and the contact portion of the first conveying unit and the third conveying unit overlaps in the first direction.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This application describes a straw bale removal machine consisting of a support assembly, a conveying assembly, a cutting assembly, and a net-removing assembly. The cutting assembly and the net-removing assembly are positioned along the conveying direction of the straw bale material. The conveying assembly transports the straw bale material, while the cutting assembly creates cutting lines on the upper and lower surfaces of the mesh packaging on the straw bale to separate the complete mesh packaging. Finally, the net-removing hooks on the net-removing assembly peel the separated mesh packaging from the straw bale, thereby automating the removal of mesh packaging from the straw bale material and improving production efficiency.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] This application discloses a straw bale netting remover 1 (hereinafter referred to as netting remover 1), with reference to Figure 1 This is a top view of the screen removal machine 1. Arrow A in the figure indicates the material conveying direction, which will be referred to as the first direction in the following description. The side of a component along the conveying direction is designated as the front, and the opposite side as the rear. The width direction of the screen removal machine 1 is indicated by arrow B in the figure. Correspondingly, the side of a component closer to the center line C in the width direction is designated as the inner side, and the side of the component farther from the center line C in the width direction is designated as the outer side. For example, in... Figure 1 The front, back, inside, and outside of component D are marked.

[0034] Reference Figure 2The diagram shows the overall structure of the netting removal machine 1. The main body of the netting removal machine 1 consists of a support component 10, a conveying component 20, a cutting component 30, and a netting removal component 40. The support component 10 serves as the mounting carrier for the conveying component 20, the cutting component 30, and the netting removal component 40. The conveying component 20 serves as the material conveying carrier. The cutting component 30 and the netting removal component 40 are arranged along the material conveying direction (i.e., the first direction). The material moves along the first direction under the action of the conveying component 20. After the cutting and removal of the netted packaging is completed at the positions of the cutting component 30 and the netting removal component 40, the material continues to run with the conveying component 20 to the next processing step. For example, the material after netting removal moves with the conveying component 20 to the entrance of the grass cutter and enters the grass cutter for subsequent grass cutting operations.

[0035] Reference Figure 3 This is a structural schematic diagram of the supporting component 10, combined with... Figure 1 The support assembly 10 mainly consists of a frame assembly 100 and a plate assembly. The frame assembly 100 is formed by overlapping several profiles and is used to support the plate assembly, forming an installation area below the plate assembly. Specifically, the frame assembly 100 includes four vertically arranged profiles 101. The horizontal projections of the four vertical profiles 101 form the four vertices of a rectangle. Correspondingly, this rectangle is denoted as a virtual rectangle. Figure 3 Continuing with the description of the structure of the support component 10, the aforementioned plate assembly includes a plate-shaped component 102, which is generally a rectangular plate-shaped component 102 extending horizontally along the first direction and the width direction. The plate-shaped component 102 is fixed to the top of the vertical profile 101, and the plate-shaped component 102 can at least cover the aforementioned virtual rectangle. In some embodiments of the screen removal machine 1, the two sides (width direction) edge lines of the aforementioned rectangular component extend vertically upward to form a limiting baffle 103, which is used to limit the material in the width direction so that the material can be conveyed in an approximately linear manner in the first direction. In other embodiments of the screen removal machine 1, the aforementioned frame assembly 100 also includes a plurality of horizontal profile groups connecting two adjacent vertical profiles 101, wherein at least one horizontal profile group is disposed on the top of the vertical profile 101 and has a surface in contact with the bottom surface of the plate-shaped component 102, so as to work together with the vertical profile 101 to support the plate-shaped component 102.

[0036] Reference Figure 6 and 7Continuing with the description of the composition of the netting removal machine 1, the cutting assembly 30 includes an upper blade 300 and a lower blade 301. Both the upper blade 300 and the lower blade 301 are circular saw blades that can rotate around their center. Through the rotation of the upper blade 300 and the lower blade 301, in conjunction with the movement of the material in the first direction, cutting lines can be formed on the upper and lower surfaces of the netting packaging, thereby cutting a complete netting packaging into two independent parts. The netting removal assembly 40 then removes the two independent parts (detailed explanation to follow). The main body of the lower blade 301 is located below the plate-shaped component 102, and at least a portion of the lower blade 301 passes through the plate-shaped component 102 and is located above the plate-shaped component 102, that is, the highest point (i.e., the cutting point) of the lower blade 301 is located above the plate-shaped component 102.

[0037] Back Figure 7 Continuing with the description of the cutting assembly 30, the rotation of the upper cutter 300 and the lower cutter 301 can be driven by the first drive assembly 302. The first drive assembly 302 may include a motor and a reducer. The upper cutter 300 and the lower cutter 301 are respectively mounted on the output shafts of the two reducers. The rotation of the upper cutter 300 and the lower cutter 301 is achieved by the motor. The motor and reducer used to drive the rotation of the lower cutter 301 are mounted on the lower surface of the plate-shaped component 102. The motor and reducer used to drive the rotation of the upper cutter 300 are mounted on the support assembly 10 through the bracket assembly 303. Specifically, the bracket assembly 303 includes a roughly gate-shaped bracket component 304 and a connecting arm 306 that connects the mounting frame 305, which contains the motor and other components, to the bracket component 304. The bracket component 304 has two opposing vertical rods 304a. The crossbar 304b connects the two vertical bars. The two vertical bars 304a are fixed on the support assembly 10, and the fixed height of the crossbar 304b on the vertical bars 304a is adjustable. For example, the height adjustment of the crossbar 304b can be achieved by fixing a plate with through holes at both ends of the crossbar 304b and a plate with an approximately rectangular groove on the side end face of the vertical bars 304a. At this time, the crossbar 304b can be locked and fixed after the position is adjusted by bolts. At the same time, one end of the connecting arm 306 is rotatably installed in the middle position of the crossbar 304b of the bracket assembly 304, and the other end of the connecting arm 306 is fixedly connected to the mounting frame 305. At this time, the height of the cutting point of the upper tool 300 can be adjusted by adjusting the height of the crossbar 304b, and the height of the cutting point of the upper tool 300 can also be adjusted by rotating the connecting arm 306.

[0038] In some embodiments of the screen removal machine 1, the upper cutter 300 and the lower cutter 301 are both arranged parallel to the orthographic projection plane (i.e., the projection in the width direction) of the screen removal machine 1, and both are arranged along the center line C of the screen removal machine 1. This enables symmetrical cutting of the mesh packaging, dividing the mesh packaging into two approximately equal-sized parts. Simultaneously, the positions of the upper cutter 300 and the lower cutter 301 in the first direction are staggered, meaning that the cutting points of the upper cutter 300 and the lower cutter 301 are spaced a certain distance apart in the first direction. For example, as shown... Figure 1 As shown, the upper cutter 300 is positioned in front of the lower cutter 301. This staggered design of the upper cutter 300 and the lower cutter 301 ensures that their cutting times are staggered, thus preventing the two cutting movements from interfering with each other and improving the stability of the material during the conveying process.

[0039] Reference Figure 2 , 8 9 and 10, the composition of the screen removal assembly 40 will now be described. The screen removal assembly 40 is positioned in front of the cutting assembly 30, meaning that after the material is processed by the cutting assembly 30, it undergoes further processing by the screen removal mechanism 400. Specifically, the screen removal assembly 40 includes two screen removal mechanisms 400 arranged opposite each other in the width direction. The two screen removal mechanisms 400 have the same composition. Now, we will select... Figure 1The following describes the composition of the net-removing mechanism 400 located below. The net-removing mechanism 400 includes at least one net-removing hook 401. This hook 401 is capable of moving on a horizontal plane, and its movement trajectory is a closed curve connecting its ends. This closed curve encloses a closed surface. For ease of description, the movement trajectory of the hook 401 is referred to as the net-removing path 402. The hook 401 is approximately a blade with an obtuse triangular cross-section, having a pointed end 401a and a wide end 401b (the net-removing path 402 coincides with the movement path of the wide end 401b). Its pointed end 401a is inclined towards the direction of movement of the hook 401. When the hook 401 moves along the net-removing path 402, its… The tip 401a always remains outside the closed surface (i.e., the movement path of the tip 401a is located outside the net-removing path 402). Simultaneously, there is an approach point 402c and a first turning point 402d on the net-removing path 402. The net-removing path 402 is divided into two paths by the approach point 402c and the first turning point 402d. These two paths are respectively denoted as the first path 402a and the second path 402b. The first path 402a and the second path 402b will now be explained in conjunction with the operation of the net-removing component 40. The first path 402a is entirely located inside the second path 402b. When the net-removing hook 401 moves to the approach point 402c, the tip of the net-removing hook 401... End 401a contacts the mesh packaging of the material. The mesh packaging peels off the material and moves along the first path with the hook 401 to the first turning point 402d. When the hook 401 carrying the mesh packaging reaches the first turning point 402d, it moves along the second path 402b from the first turning point 402d to the approach point 402c. During the movement of the hook 401 along the second path 402b, the mesh packaging falls off the tip 401a of the hook 401 (the process of the mesh packaging falling off will be explained later). The hook 401 returns to the approach point 402c and contacts the mesh packaging of the next material. That is, the movement of the hook 401 is a cyclic reciprocating motion. During the movement of the net-removing hook 401 along the trajectory of approach point 402c - first turning point 402d - approach point 402c, that is, during the movement along the first path 402a - second path 402b, the net-removing mechanism 400 completes a net-removing and net-removing workflow. The net-removing mechanism 400 continuously repeats this workflow, in conjunction with the material continuously conveyed in the first direction, thereby realizing the continuous operation of the net-removing machine 1. In some embodiments of the net-removing machine 1, the net-removing blades in the above-mentioned net-removing machine 1 are provided in multiple ways. The multiple net-removing blades are distributed at intervals along the net-removing path 402. Each net-removing blade can independently complete the above-mentioned net-removing and net-removing workflow. The continuous operation of multiple net-removing blades can further improve the working efficiency of the net-removing machine 1.

[0040] Reference Figure 8and 9 The above-described net removal process will now be explained in conjunction with the remaining components of the net removal mechanism 400. The net removal mechanism 1 also includes a housing component 403, which at least includes a base plate portion 404 and a side wall portion 405. The base plate portion 404 is arranged parallel to the horizontal plane and has an edge line with a shape similar to the net removal path 402. Preferably, the edge line of the base plate portion 404 is the horizontal projection of the net removal path 402. The side wall portion 405 is a baffle component that extends vertically upward along the closed path to surround the net removal path 402. The device has a first section 405a and a second section 405b. The first section 405a of the sidewall portion 405 is arranged approximately along the first path 402a of the net-removing path 402, and an opening is provided in the first section 405a for the net-removing hook 401 to pass through. That is, when the net-removing hook 401 moves along the first path 402a, the tip 401a of the net-removing hook 401 is located on the periphery of the sidewall portion 405 so that it can contact and remove the mesh packaging. The wide end 401b of the net-removing path 402 is located inside the sidewall portion 405. The thickness of the opening is slightly greater than the thickness of the net-removing hook 401. In some embodiments of the net-removing machine 1, at least a portion of the second section 405b of the aforementioned sidewall portion 405 is located outside the second path 402b, that is, there is a gap between at least a portion of the second section 405b and the second path 402b of the net-removing path 402, and the gap is greater than the length of the net-removing hook 401. That is, when the net-removing hook 401 moves in this portion of the section, the tip 401a of the net-removing hook 401 is located inside the sidewall portion 405. At this time, the net-removing hook 401 moves along the net-removing path 402b. 02 During the movement, there is an inflection point, namely, the point where the tip 401a of the net-removing hook 401 turns from the outer position of the side wall 405 to the inner position of the side wall 405. When the net-removing hook 401 carrying the mesh packaging passes through this point, the mesh packaging falls off the net-removing hook 401 to complete the net removal operation. In conjunction with the above discussion of the net removal process, the net-removing hook 401 can continuously repeat the net removal and net removal process during the reciprocating movement along the net removal path 402 to remove the net from the continuously conveyed material.

[0041] In some embodiments of the net removal path 402, the net removal hook 401 is mounted on a chain. Specifically, the wide end 401b of the net removal hook 401 is mounted on the chain, and the chain is set along the net removal path 402. At the same time, the net removal mechanism 400 is provided with a sprocket adapted to the chain. In some embodiments of the net removal machine 1, there are two sprockets, which are respectively referred to as sprocket one 406 and sprocket two 407. Sprocket one 406 is the driving wheel, which rotates under the action of a motor or other driving components. The meshing point of sprocket one 406 with the chain is the first turning point 402d. Sprocket two 407 is the driven wheel, and the meshing point of sprocket two 407 with the chain is the approach point 402c.

[0042] In a preferred embodiment of the net removal machine 1, there is a second turning point 402e on the net removal path 402. Correspondingly, the net removal mechanism 400 is also provided with a sprocket 408. The meshing point of the sprocket 408 and the chain is the second turning point 402e. At this time, the net removal path 402 is roughly in the shape of an obtuse triangle, that is, the chain is set in a triangle.

[0043] Back Figure 10 The aforementioned net-removing mechanism 400 also includes a top plate component 409. The edge line of the top plate component 409 extends along the side wall portion 405 of the housing component 403, and the top plate component 409 is connected to the bottom plate portion 404 of the housing component 403. Components such as sprockets are mounted on the bottom plate portion 404 to form a whole. The aforementioned net-removing mechanism 400 also includes a support frame 410. The height of the support frame 410 can be manually adjusted to adjust the height of the bottom plate portion 404 and the net-removing hook 401, so that the net-removing hook 401 is located in the middle position of the material, ensuring the smooth progress of the net-removing operation. At the same time, the bottom plate portion 404 of the housing component 403 is rotatably mounted on the support frame 410, that is, the housing component 403 can rotate around its connection point with the support frame 410 to adjust the position of the net-removing hook 401 in the width direction, thereby realizing the processing of materials of different specifications.

[0044] Reference Figure 4 and 5 This is a structural schematic diagram of the conveying assembly 20 and the supporting assembly 10. The conveying assembly 20 includes at least two parts arranged opposite each other in the width direction, which are respectively referred to as the first conveying unit 201 and the second conveying unit 202. Both the first conveying unit 201 and the second conveying unit 202 have a contact portion 200a located above the plate-shaped member 102. The distance between the contact portion 200a and the upper surface of the plate-shaped member 102 is approximately equal to the distance between the lower cutting tool and the upper surface of the plate-shaped member 102. The conveying units are arranged along a first direction and can move along the first direction. During the operation of the screen removal machine 1, the contact portion 200a of the first conveying unit 201 and the second conveying unit 202... The material is supported and moved along a first direction to achieve material conveying. In some embodiments of the screen removal machine 1, the first conveying unit 201 and the second conveying unit 202 further include a rotating part 200b and a connecting part 200c. The rotating part 200b is located below the plate-shaped component 102 and is arranged along the first direction. The connecting part 200c is used to connect the two ends of the contact part 200a and the rotating part 200b. At this time, the first conveying unit 201 and the second conveying unit 202 are both roughly in the shape of an elongated hole. During the operation of the screen removal machine 1, each part of the first conveying unit 201 and the second conveying unit 202 moves cyclically along its contour to achieve material conveying.

[0045] Reference Figure 5 In some embodiments of the screen removal machine 1, the aforementioned conveying assembly 20 further includes a third conveying unit 203 and a fourth conveying unit 204 disposed opposite to each other in the width direction. The third conveying unit 203 and the fourth conveying unit 204 are located inside the first conveying unit 201 and the second conveying unit 202. The configuration of the third conveying unit 203 and the fourth conveying unit 204 is the same as that of the first conveying unit 201 and the second conveying unit 202. Meanwhile, the contact portion 200a of the first conveying unit 201 and the third conveying unit 203 can cover the plate-shaped component 102 in the length direction in the first direction, and the contact portion 200a of the first conveying unit 201 and the third conveying unit 203 overlaps in the first direction. Figure 5 To illustrate, the two ends of the contact portion 200a of the first conveying unit 201 are a first end 201a and a second end 201b, respectively. The two ends of the contact portion 200a of the third conveying unit 203 are a third end 203a and a fourth end 203b, respectively. The first end 201a of the first conveying unit 201 is located at the feed end of the screen remover 1. The second end 201b of the first conveying unit 201 extends along a first direction to a position at the middle of the screen remover 1. The fourth end 203b of the third conveying unit 203 is located at the discharge end of the screen remover 1. The third end 203a of the third conveying unit 203 extends in the opposite direction to the middle of the screen remover 1. (Note: The last sentence appears to be incomplete and possibly refers to a different context.) Figure 5 The contact portion 200a between the first conveying unit 201 and the third conveying unit 203 has a junction section 205. By adding the third conveying unit 203 and the fourth conveying unit 204, the material conveying process of the screen remover 1 can be divided. On the one hand, the power required by a single conveying unit can be reduced. On the other hand, due to the partially overlapping junction section 205, the stability of the material during the conveying process can be improved.

[0046] In some embodiments of the screen removal machine 1, the above-mentioned conveying assembly 20 is composed of a chain drive mechanism, that is, the first conveying unit 201, the second conveying unit 202, the third conveying unit 203 and the fourth conveying unit 204 are all complete chains, and the conveying assembly 20 is equipped with sprockets adapted to the chain and motors and other components that drive the sprockets to rotate.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
