Abstract
Description
Technical Field
[0001] This utility model relates to the field of potato harvesting equipment technology, specifically to a novel vine-removing mechanism for potato harvesters. Background Technology
[0002] Potato harvesters consist of a digging mechanism for digging and a separating mechanism for separating the potatoes from the vines. However, most potato harvesters on the market currently transport all the potatoes and vines to the separating mechanism for separation, resulting in a large number of potatoes and high separation pressure on the separating mechanism when separating the potatoes and vines.
[0003] To solve the above-mentioned technical problems, Chinese invention patent with publication number CN117882552A provides a hooking mechanism, a separation component and a potato harvester. By setting up a hooking mechanism, potatoes that are only connected to the vines are transported to the rear end for separation of the vines and potatoes, thereby reducing the separation pressure when separating potatoes and vines in the later stage.
[0004] However, during the process of transporting potato vines, the hooking mechanism cannot separate the potatoes from the vines, resulting in all potatoes connected to the vines being transported to the rear end for separation. This leads to a relatively high pressure on the rear end for separating the potatoes from the vines. Utility Model Content
[0005] In view of the deficiencies in the prior art, the purpose of this utility model is to provide a new type of vine removal mechanism for potato harvesters, so as to solve or alleviate the above-mentioned technical problems existing in the prior art.
[0006] To achieve the above objectives, this utility model provides a novel vine-removing mechanism for a potato harvester, comprising a conveying assembly and a hooking assembly. The conveying assembly includes a carrying rod, and the hooking assembly includes a plurality of hooking rods arranged at intervals along the length direction of the carrying rod. It also includes a separating assembly, which includes a plurality of first separating rods arranged at intervals along the length direction of the carrying rod. Each first separating rod is connected to a frame, and its second end extends towards the conveying surface of the conveying assembly. When a hooking rod corresponds to a first separating rod, at least one first separating rod is provided between any two adjacent hooking rods.
[0007] Furthermore, the separation assembly also includes a torsion spring, wherein a first end of the first separation rod is hinged to the vehicle frame and a second end is capable of swinging in the positive direction from an initial position about its hinge center line, wherein when the first separation rod is in the initial position, the distance between the second end of the first separation rod and the conveying surface of the conveying assembly is small;
[0008] The torsion spring is located at the hinge center of the first separating rod, and in its natural state, the torsion spring applies a spring force to the first separating rod so that the second end of the first separating rod tends to swing in the opposite direction around its hinge center line.
[0009] Furthermore, when the first separating rod is in its initial position, the axis of the first separating rod is perpendicular to the conveying surface of the conveying assembly.
[0010] Furthermore, a first separating rod is provided between any two adjacent hook grass rods.
[0011] Furthermore, the separation assembly also includes a second separation rod, which corresponds one-to-one with the first separation rod. When the hook grass rod corresponds to the first separation rod, a first separation rod and a second separation rod are provided between any two adjacent hook grass rods. The first end of the second separation rod is connected to the vehicle frame, and the second end extends toward the conveying surface of the conveying assembly.
[0012] Furthermore, a first separating rod and a second separating rod are grouped together, and the second separating rod and the first separating rod in the same group are connected.
[0013] Furthermore, the first separating rod and the second separating rod of the same group are located on both sides of the same hook rod.
[0014] Furthermore, the centerlines of all the first and second separating rods are in the same plane and parallel to each other.
[0015] Furthermore, multiple separation components are provided, and the multiple separation components are arranged sequentially at intervals along the conveying surface of the conveying component.
[0016] The beneficial effects of this utility model are:
[0017] The novel vine-removing mechanism for potato harvesters provided by this utility model, by setting a first separating rod, allows for the separation of some potatoes connected to the vines during the vine-removing process, through the cooperation of the hook rod and the first separating rod, thereby reducing the separation pressure at the rear end for separating the vines and potatoes.

[0031] like Figure 1-4 As shown, this utility model provides a novel vine-removing mechanism for a potato harvester, which is installed on the potato harvester.
[0032] The potato harvester includes a frame 100 and a digging mechanism (not shown in the attached drawing), a feeding mechanism (not shown in the attached drawing), a new type of vine removal mechanism, and a conveying mechanism (not shown in the attached drawing) mounted on the frame 100.
[0033] The digging mechanism is located at the front end of the frame 100. It penetrates the soil layer where the potatoes grow to sever the connection between the potatoes and the soil, thereby separating the potatoes, vines, and surrounding soil from the ground. As the harvester moves forward, these materials are transported to the feeding mechanism. Here, we refer to the potatoes, vines, and surrounding soil transported from the digging mechanism collectively as the first material.
[0034] The feeding mechanism is located behind the excavating mechanism. The feeding mechanism is used to transport the first material from front to back, and during the transportation process, some of the soil in the first material can fall back to the ground.
[0035] The conveying mechanism is located behind the feeding mechanism, and the inlet end of the conveying mechanism is located below the outlet end of the feeding mechanism. The conveying mechanism is used to convey the third material from front to back, and during the conveying process, the soil in the third material can fall back to the ground. The third material includes potatoes and soil that fall from the feeding mechanism and the above-mentioned new seedling removal mechanism.
[0036] The aforementioned novel vine-removing mechanism is located behind the feeding mechanism, with its inlet end positioned below the outlet end of the feeding mechanism and above the inlet end of the conveying mechanism. This mechanism separates the second material from the first material conveyed by the feeding mechanism and transports it from bottom to top. During this transport process, the mechanism separates potatoes from the second material, causing them to fall onto the conveying mechanism. The second material includes potato vines, potatoes not separated from the vines, and soil mixed in with the vines.
[0037] The new seedling removal mechanism includes a conveying component and a grass-hooking component mounted on the conveying component.
[0038] The conveying assembly is inclinedly mounted on the frame 100 so that the soil and potatoes in the second material can fall onto the conveying mechanism under the action of gravity. The conveying assembly is used to convey the material from bottom to top. The conveying assembly includes multiple conveyor belts 211 arranged at intervals in sequence and multiple support rods 212 arranged at intervals in sequence along the circumference of the conveyor belts 211. The support rods 212 are fixedly connected to the conveyor belts 211.
[0039] The hooking assembly includes multiple hooking units arranged sequentially at intervals along the circumference of the conveyor belt 211. Each hooking unit includes multiple hooking rods 221, which are arranged sequentially at intervals along the length of the support rod 212. The first end of each hooking rod 221 is connected to the support rod 212, and the second end extends inward away from the conveyor belt 211. The distance between any two adjacent hooking rods 221 is adapted to the size of the potato, allowing the potato to pass through the gap between the two hooking rods 221. During operation, the potato, separated from the vine, passes through the gap between the two hooking rods 221 under the influence of gravity and eventually falls onto the conveyor structure below.
[0040] Preferably, the hook stalk 221 is V-shaped or hook-shaped to improve the hooking effect.
[0041] These are all existing technologies, and will not be elaborated on here. For details, please refer to the invention patent application number 2023103141941, which provides a hooking mechanism, a separating component, and a potato harvester.
[0042] The novel seedling removal mechanism also includes a separation component, which comprises a plurality of first separation rods 231. The plurality of first separation rods 231 are arranged sequentially at intervals along the length direction of the support rod 212, and when the hook rod 221 corresponds to the first separation rod 231, at least one first separation rod 231 is provided between any two adjacent hook rods 221. The first end of the first separation rod 231 is connected to the frame 100, and the second end extends toward the conveying surface of the conveying component.
[0043] Specifically, in this embodiment, when the hook stalk 221 corresponds to the first separating rod 231, only one first separating rod 231 is provided between any two adjacent hook stalks 221. Of course, in other embodiments, multiple first separating rods 231 can be provided between any two adjacent hook stalks 221.
[0044] During operation, the first material conveyed by the feeding mechanism falls downwards from the discharge end of the feeding mechanism. The second material is hooked by the hook rod 221 and cannot fall further. Under the action of the conveying assembly, it is conveyed from bottom to top. During the conveying process, when the second material is conveyed to the first separating rod 231, the cooperation between the first separating rod 231 and the hook rod 221 reduces the gap for the second material to pass through, thus preventing potatoes larger than the gap from passing through and intercepting them.
[0045] As the conveying process continues, the hook stalk 221 applies an upward first force to the potato through the potato vine, while the first separating stalk 231 applies a downward second force. The combined effect of these two forces creates a tensile force between the potato and the vine, causing the connection between them to break, thus separating the potato from the vine. The separated potato falls downwards under gravity, while the vine continues to be transported by the conveying assembly under the action of the hook stalk assembly. The structure is simple and can separate some potatoes during the vine conveying process, thereby reducing the pressure on the potato separation stage.
[0046] like Figures 1-4 As shown, in this embodiment, the separation assembly further includes a torsion spring 232. The first end of the first separation rod 231 is hinged to the frame 100, and the second end is capable of swinging in the positive direction from its initial position around its hinge center line. When the first separation rod 231 is in its initial position, the distance between the second end of the first separation rod 231 and the conveying surface of the conveying assembly is small. Preferably, when the first separation rod 231 is in its initial position, the axis of the first separation rod 231 is perpendicular to the conveying surface of the conveying assembly.
[0047] The torsion spring 232 is disposed at the hinge center of the first separating rod 231. In its natural state, the torsion spring 232 applies a spring force to the first separating rod 231, so that the second end of the first separating rod 231 tends to swing in the opposite direction around its hinge center line. Under the action of this spring force, in its natural state, the first separating rod 231 can be held in its initial position.
[0048] Specifically, the separation assembly also includes a hinge shaft 234 and a first limiting rod 235.
[0049] The two ends of the hinge shaft 234 are fixedly connected to the frame 100, the first end of the first separating rod 231 is sleeved on the hinge shaft 234 and hinged to the hinge shaft 234, and the torsion spring 232 is sleeved on the hinge shaft 234.
[0050] Both ends of the first limiting rod 235 are fixedly connected to the frame 100. When the first separating rod 231 is in the initial position, the side of the first separating rod 231 facing the conveying assembly abuts against the first separating rod 231 to limit the first separating rod 231. Thus, in the natural state, under the combined action of the torsion spring 232 and the first limiting rod 235, the first separating rod 231 can be held in the initial position.
[0051] Specifically, the separation assembly also includes a second limiting rod 236, a first connecting part 201 of the torsion spring 232 connected to the second limiting rod 236, and a second connecting part 202 connected to the first separation rod 231.
[0052] Preferably, the torsion spring 232 includes two helical portions 203, which are respectively disposed on both sides of the first separating rod 231. The second connecting portion 202 is U-shaped and is disposed between the two helical portions 203 and fixedly connected to them. This structure allows the torsion spring 232 to exert a more uniform elastic force on the first separating rod 231.
[0053] During operation, when the force exerted on the first separating rod 231 by the potato exceeds a preset value, it can push the first separating rod 231 to swing, thereby avoiding damage to the potato caused by the large reaction force exerted on the potato by the first separating rod 231.
[0054] like Figures 1-4 As shown, in this embodiment, the separation assembly further includes a second separation rod 233, which corresponds one-to-one with the first separation rod 231. When the hook grass rod 221 corresponds to the first separation rod 231, a first separation rod 231 and a second separation rod 233 are provided between any two adjacent hook grass rods 221. The first end of the second separation rod 233 is connected to the frame 100, and the second end extends towards the conveying surface of the conveying assembly.
[0055] During operation, the cooperation of the first separating rod 231, the second separating rod 233, and the hook rod 221 further reduces the gap for the second material to pass through, thereby improving the separation effect.
[0056] As shown in Figure 1- Figure 4 As shown, in this embodiment, a first separating rod 231 and a second separating rod 233 are grouped together. The second separating rod 233 in the same group is fixedly connected to the first separating rod 231, so that the second separating rod 233 can swing together with the first separating rod 231, thereby avoiding damage to the potato caused by the large reaction force applied to the potato by the second separating rod 233.
[0057] Specifically, the first end of the second separating rod 233 is fixedly connected to the first separating rod 231 via a connecting rod 237. Specifically, the first end of the connecting rod 237 is fixedly connected to the first separating rod 231, and the second end is fixedly connected to the first end of the second separating rod 233.
[0058] like Figures 1-4 As shown, the first separating rod 231 and the second separating rod 233 of the same group are located on both sides of the same hook rod 221, so that the force applied by the first separating rod 231 and the second separating rod 233 to the potato vine hooked by the hook rod 221 located in the middle is equal, thereby avoiding the potato vine from falling off the hook rod 221 due to the unequal force applied on both sides of the potato vine, thus achieving the purpose of improving the separation effect.
[0059] As shown in Figure 1- Figure 4 As shown, the centerlines of all the first separation rods 231 and the second separation rods 233 are in the same plane and parallel to each other.
[0060] As shown in Figure 1- Figure 4 As shown, in this embodiment, multiple separation components are provided, and these components are arranged sequentially and at intervals along the conveying surface of the conveying component to improve the separation effect on potatoes, enabling more potatoes to be separated, thereby further reducing the pressure of subsequent separation of potatoes and vines.
[0061] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.
[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
