Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to a portable cassava harvesting device. Background Technology

[0002] Currently, there are two main methods for cassava harvesting: manual labor and mechanical digging. Traditionally, farmers use hoes or shovels to dig around the cassava plants, loosening the soil before pulling the cassava tubers out. This method is extremely labor-intensive, inefficient, and can easily damage the tubers during the digging process, reducing the quality and yield of the cassava.

[0003] Existing small-scale potato harvesting machinery is large, heavy, inconvenient to operate, and labor-intensive; while existing large-scale harvesting machinery is bulky, complex in structure, expensive, and also inconvenient to operate. Furthermore, mechanical digging requires an external power source, such as a diesel engine, which not only increases operating costs but also makes it difficult to move in the field, unsuitable for small plots of land or planting areas with complex terrain. At the same time, mechanical digging has high maintenance costs, placing a heavy economic burden on ordinary farmers cultivating small areas, hindering its widespread adoption. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a portable cassava harvesting device to solve the above-mentioned problem.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A portable cassava harvesting device includes: a telescopic mechanism, a gripping mechanism, a supporting mechanism, and a clamping mechanism. The supporting mechanism is fixedly disposed at one end of the telescopic mechanism. The clamping mechanism includes a first clamping plate and a second clamping plate, which are spaced apart. The first clamping plate is rotatably mounted on the supporting mechanism, and the second clamping plate is fixedly disposed on the supporting mechanism. One end of the gripping mechanism is fixedly disposed on the telescopic mechanism, and the other end passes through the second clamping plate and is fixedly connected to the first clamping plate, for driving the first clamping plate to move closer to or away from the second clamping plate.

[0006] The beneficial effects of this utility model are as follows: This utility model drives the first clamping plate to approach the second clamping plate through the gripping mechanism, which is conducive to clamping the cassava stalk. The clamping mechanism, support mechanism and telescopic mechanism are conducive to forming a lever structure. With the support mechanism as the fulcrum, the cassava clamped by the first clamping plate and the second clamping plate is pulled out of the soil by pressing down the telescopic mechanism. Compared with the existing technology of manually digging cassava, this utility model is conducive to reducing labor intensity, improving work efficiency, and avoiding damage to the cassava tuber during the cassava pulling process, thus enhancing the quality of the cassava. Compared with the large or small cassava pulling machines in the existing technology, this utility model does not require additional external power, has low operating costs, is small in size and easy to carry, and is simple to operate. It is suitable for promotion and use in small-area planting or planting in complex terrain.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the support base includes a support plate and a connecting plate. One end of the support plate and one end of the connecting plate are perpendicular to and fixedly connected. One end of the support plate and one end of the connecting plate are both fixedly connected to the middle of the side wall of the connecting rod. One end of the telescopic mechanism is fixedly connected to the connecting plate. The first clamping plate is rotatably mounted on the support plate, and the second clamping plate is fixedly mounted on the support plate.

[0011] The beneficial effect of adopting the above-mentioned further solution is that one end of the support plate and one end of the connecting plate are perpendicular and fixedly connected, which helps to make the clamping mechanism and the telescopic mechanism form a vertical structure in space, thereby facilitating the force exertion of the lever structure.

[0012] Furthermore, a second hinge shaft is rotatably provided inside the support plate, one end of the first clamping plate is disposed inside the support plate, and the second hinge shaft rotatably passes through the bottom end of the first clamping plate.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the second hinge shaft facilitates the rotatable mounting of the first clamping plate on the support plate, thereby making it easier for the first clamping plate to approach the second clamping plate under the driving action of the gripping mechanism, so as to clamp the cassava stalk and facilitate subsequent pulling.

[0014] Furthermore, the telescopic mechanism includes: an outer tube, an inner slide rod, and a locking member. The outer tube is slidably fitted onto the inner slide rod. The locking member is threaded through the side wall of the outer tube and abuts against or separates from the side wall of the inner slide rod. One end of the outer tube is fixedly connected to the support mechanism.

[0015] The beneficial effects of adopting the above-mentioned further solution are: the outer sleeve can be slidably fitted onto the inner slide rod, which is conducive to adjusting the length of the telescopic mechanism, thereby adjusting the effort-saving situation when pulling cassava; the locking part abuts against or separates from the side wall of the inner slide rod, which is conducive to fixing the telescopic mechanism after length adjustment, or canceling the fixing, and facilitating the inner slide rod to slide inside the outer sleeve for length adjustment.

[0016] Furthermore, the locking component includes a locking bolt and a locking handle. The top end of the locking bolt is fixed and vertically connected to one end of the locking handle. A threaded through hole is provided on the side wall of the outer sleeve. The locking bolt passes through the threaded through hole. The bottom end of the locking bolt abuts against or separates from the side wall of the inner slide rod.

[0017] The beneficial effects of adopting the above-mentioned further solution are: the top of the locking bolt is fixed and vertically connected to one end of the locking handle, which makes it convenient for the user to adjust the tightness of the locking bolt; the bottom of the locking bolt abuts against or separates from the side wall of the inner slide rod, which is conducive to fixing the telescopic mechanism after length adjustment, or canceling the fixing, and making it convenient for the inner slide rod to slide in the outer tube for length adjustment.

[0018] Furthermore, the gripping mechanism includes: a fixed sleeve, a grip handle, and a pulling member. The fixed sleeve is fixedly sleeved on the telescopic mechanism. One end of the grip handle is hinged to the fixed sleeve through a first hinge shaft. One end of the pulling member is fixedly connected to the grip handle, and its other end passes through the second clamping plate and is fixedly connected to the first clamping plate.

[0019] The beneficial effect of adopting the above-mentioned further solution is that one end of the grip handle is hinged to the fixed sleeve through the first hinge shaft, which is conducive to changing the position of the grip handle through the hinge, thereby realizing the pulling effect on the pulling member, and then driving the first clamping plate to approach the second clamping plate to complete the clamping and fixing of the cassava stalk.

[0020] Furthermore, the pulling component includes a connecting sleeve and a pulling rope. The connecting sleeve is sleeved on the pulling rope, and the pulling rope can movably pass through the connecting sleeve. The two ends of the connecting sleeve are fixedly connected to the fixing sleeve and the second clamping plate, respectively, and the two ends of the pulling rope are fixedly connected to the grip handle and the first clamping plate, respectively.

[0021] The beneficial effect of adopting the above-mentioned further solution is that the two ends of the pull rope are fixedly connected to the grip handle and the first clamping plate respectively, which is conducive to the pull rope being pulled and moved in the connecting sleeve when the position of the grip handle is changed by the hinge, thereby bringing the first clamping plate closer to the second clamping plate and completing the clamping and fixing of the cassava stalk.

[0022] Furthermore, it also includes a spring, the two ends of which are fixedly connected to the opposite sidewalls of the first clamping plate and the second clamping plate, and the spring is sleeved on the pulling rope.

[0023] The beneficial effect of adopting the above-mentioned further solution is that the spring can use its rebound force to drive the first clamping plate to rotate away from the second clamping plate, thereby realizing the automatic separation of the first clamping plate and the second clamping plate after the cassava is pulled out.

[0024] Furthermore, multiple toothed blocks are provided on the opposite sidewalls of the first clamping plate and the second clamping plate.

[0025] The beneficial effect of adopting the above-mentioned further solution is that the toothed block helps to increase the friction between the cassava stem and the first clamping plate and the second clamping plate, thereby making it easier to pull out the cassava. Attached Figure Description

[0029] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0030] like Figures 1 to 6 As shown, this embodiment provides a portable cassava harvesting device, including: a telescopic mechanism 1, a gripping mechanism 2, a support mechanism 3, and a clamping mechanism 4. The support mechanism 3 is fixedly disposed at one end of the telescopic mechanism 1. The clamping mechanism 4 includes a first clamping plate 41 and a second clamping plate 42, which are spaced apart. The first clamping plate 41 is rotatably mounted on the support mechanism 3, and the second clamping plate 42 is fixedly disposed on the support mechanism 3. One end of the gripping mechanism 2 is fixedly disposed on the telescopic mechanism 1, and the other end passes through the second clamping plate 42 and is fixedly connected to the first clamping plate 41, for driving the first clamping plate 41 to move closer to or away from the second clamping plate 42.

[0031] It should be noted that in this embodiment, the first clamping plate 41 and the second clamping plate 42 are symmetrically arranged arc-shaped plate structures, which are conducive to adapting to the shape of the cassava stalk, thereby ensuring the stability of the cassava stalk after the first clamping plate 41 and the second clamping plate 42 clamp it.

[0032] The beneficial effects of this utility model are as follows: This utility model drives the first clamping plate to approach the second clamping plate through the gripping mechanism, which is conducive to clamping the cassava stalk. The clamping mechanism, support mechanism and telescopic mechanism are conducive to forming a lever structure. With the support mechanism as the fulcrum, the cassava clamped by the first clamping plate and the second clamping plate is pulled out of the soil by pressing down the telescopic mechanism. Compared with the existing technology of manually digging cassava, this utility model is conducive to reducing labor intensity, improving work efficiency, and avoiding damage to the cassava tuber during the cassava pulling process, thus enhancing the quality of the cassava. Compared with the large or small cassava pulling machines in the existing technology, this utility model does not require additional external power, has low operating costs, is small in size and easy to carry, and is simple to operate. It is suitable for promotion and use in small-area planting or planting in complex terrain.

The support base 33 is fixedly disposed in the middle of the side wall of the connecting rod 32. One end of the telescopic mechanism 1 is fixedly connected to the support base 33. The first clamping plate 41 is rotatably mounted on the support base 33, and the second clamping plate 42 is fixedly disposed on the support base 33.

[0034] It should be noted that, in use, in the lever structure formed by the clamping mechanism 4, the support mechanism 3, and the telescopic mechanism 1, the support mechanism 3 can be used as a fulcrum and / or the cassava stalk clamped by the first clamping plate 41 and the second clamping plate 42 can be used as a fulcrum. However, since the two rollers 31 in the support mechanism 3 are rotatably mounted on both ends of the connecting rod 32 in a one-to-one correspondence, if the support mechanism 3 is used as a fulcrum, the farmer can step on one of the rollers 31 with one foot during the process of pulling out the cassava to prevent the roller 31 from rotating during the process of pulling out the cassava.

One end of the support plate 331 and one end of the connecting plate 332 are perpendicular to and fixedly connected. One end of the support plate 331 and one end of the connecting plate 332 are both fixedly connected to the middle of the side wall of the connecting rod 32. One end of the telescopic mechanism 1 is fixedly connected to the connecting plate 332. The first clamping plate 41 is rotatably mounted on the support plate 331, and the second clamping plate 42 is fixedly mounted on the support plate 331.

[0037] The advantages of adopting the above preferred solution are: one end of the support plate and one end of the connecting plate are perpendicular and fixedly connected, which helps to make the clamping mechanism and the telescopic mechanism form a vertical structure in space, thereby facilitating the force exertion of the lever structure.

[0038] Preferred, such as Figure 5 As shown, a second hinge shaft 44 is rotatably disposed inside the support plate 331, one end of the first clamping plate 41 is disposed inside the support plate 331, and the second hinge shaft 44 rotatably passes through the bottom end of the first clamping plate 41.

[0039] The advantages of adopting the above preferred solution are: the second hinge shaft facilitates the rotatable mounting of the first clamping plate on the support plate, thereby making it easier for the first clamping plate to approach the second clamping plate under the driving action of the gripping mechanism, so as to clamp the cassava stalk and facilitate subsequent pulling.

[0040] Preferred, such as Figure 1 As shown, the telescopic mechanism 1 includes: an outer tube 11, an inner slide rod 12, and a locking member 13. The outer tube 11 is slidably sleeved on the inner slide rod 12. The locking member 13 is threaded through the side wall of the outer tube 11 and abuts against or separates from the side wall of the inner slide rod 12. One end of the outer tube 11 is fixedly connected to the support mechanism 3.

[0041] It should be noted that in this embodiment, since the outer sleeve 11 is slidably sleeved on the inner slide rod 12, the end of the outer sleeve 11 away from the inner slide rod 12 is fixedly connected to the connecting plate 332. One end of the outer sleeve 11 is fixedly connected to the connecting plate 332.

[0042] The advantages of adopting the above preferred solution are: the outer sleeve can be slidably fitted onto the inner slide rod, which is conducive to adjusting the length of the telescopic mechanism, thereby adjusting the effort-saving situation when pulling cassava; the locking part abuts against or separates from the side wall of the inner slide rod, which is conducive to fixing the telescopic mechanism after length adjustment, or canceling the fixing, and facilitating the inner slide rod to slide inside the outer sleeve for length adjustment.

[0043] Preferred, such as Figure 4As shown, the locking member 13 includes a locking bolt 131 and a locking handle 132. The top end of the locking bolt 131 is fixed and vertically connected to one end of the locking handle 132. A threaded through hole is provided on the side wall of the outer sleeve 11. The locking bolt 131 passes through the threaded through hole. The bottom end of the locking bolt 131 abuts against or separates from the side wall of the inner slide rod 12.

[0044] The advantages of adopting the above preferred solution are: the top of the locking bolt is fixed and vertically connected to one end of the locking handle, which makes it easy for the user to adjust the tightness of the locking bolt; the bottom of the locking bolt abuts against or separates from the side wall of the inner slide rod, which is conducive to fixing the telescopic mechanism after length adjustment, or canceling the fixing, and making it easy for the inner slide rod to slide in the outer tube for length adjustment.

[0045] Preferred, such as Figures 1 to 3 , Figure 5 As shown, the gripping mechanism 2 includes: a fixed sleeve 21, a grip handle 22, and a pulling member 23. The fixed sleeve 21 is fixedly sleeved on the telescopic mechanism 1. One end of the grip handle 22 is hinged to the fixed sleeve 21 through a first hinge shaft 24. One end of the pulling member 23 is fixedly connected to the grip handle 22, and its other end passes through the second clamping plate 42 and is fixedly connected to the first clamping plate 41.

[0046] It should be noted that in this embodiment, since the outer sleeve 11 is slidably sleeved on the inner slide rod 12, the fixing sleeve 21 is fixedly sleeved on the side wall of the inner slide rod 12 away from the outer sleeve 11. The grip handle 22 is provided with anti-slip texture, which helps to increase friction, prevent the hand from slipping during operation, and improve operating comfort and safety.

[0047] The advantages of adopting the above preferred solution are: one end of the grip handle is hinged to the fixed sleeve through the first hinge shaft, which is conducive to changing the position of the grip handle through the hinge, thereby realizing the pulling effect on the pulling member, and then driving the first clamping plate to approach the second clamping plate to complete the clamping and fixing of the cassava stalk.

[0048] Preferred, such as Figures 1 to 3 , Figure 5 As shown, the pulling member 23 includes a connecting sleeve 231 and a pulling rope 232. The connecting sleeve 231 is sleeved on the pulling rope 232, and the pulling rope 232 can movably pass through the connecting sleeve 231. The two ends of the connecting sleeve 231 are fixedly connected to the fixing sleeve 21 and the second clamping plate 42 respectively, and the two ends of the pulling rope 232 are fixedly connected to the grip handle 22 and the first clamping plate 41 respectively.

[0049] It should be noted that, in this embodiment, as Figure 1 As shown, after the length of the telescopic mechanism 1 is adjusted, the connecting sleeve 231 can be fixed to the outer sleeve 11 and / or the inner slide rod 12 by the strap 25. At this time, since the connecting sleeve 231 is sleeved on the pulling rope 232, and the pulling rope 232 can move through the connecting sleeve 231, the fixing of the connecting sleeve 231 by the strap 25 will not affect the movement of the pulling rope 232 inside it.

[0050] The advantages of adopting the above-mentioned preferred solution are: the two ends of the pull rope are fixedly connected to the grip handle and the first clamping plate respectively, which is beneficial to the pull rope being pulled and moved in the connecting sleeve when the position of the grip handle is changed by the hinge, thereby bringing the first clamping plate closer to the second clamping plate and completing the clamping and fixing of the cassava stalk.

[0051] Preferred, such as Figure 1 and Figure 5 As shown, it also includes a spring 43, the two ends of which are fixedly connected to the side walls opposite to the first clamping plate 41 and the second clamping plate 42, and the spring 43 is sleeved on the pulling rope 232.

[0052] The advantages of adopting the above preferred solution are: the spring can use its rebound force to drive the first clamping plate to rotate away from the second clamping plate, thereby realizing the automatic separation of the first clamping plate and the second clamping plate after the cassava is pulled out.

[0053] Preferred, such as Figure 1 and Figure 5 As shown, multiple toothed blocks 45 are provided on the opposite sidewalls of the first clamping plate 41 and the second clamping plate 42.

[0054] It should be noted that in this embodiment, the toothed block 45 is made of rubber, which helps to avoid damage to the cassava stem during clamping and also increases the friction between the toothed block 45 and the cassava stem.

[0055] The beneficial effect of adopting the above-mentioned preferred solution is that the toothed block helps to increase the friction between the cassava stem and the first clamping plate and the second clamping plate, thereby making it easier to pull out the cassava.

[0056] The working process of this embodiment is described below: like Figures 1 to 6 As shown, before pulling up cassava, cut the cassava stalks a certain distance off the ground; Then, using two rollers 31, the entire device is moved closer to the cassava stalk, and then the entire device is... Figure 1The view shown rotates 90 degrees counterclockwise around the connecting rod 32, and the cassava stalk passes between the first clamping plate 41 and the second clamping plate 42, forming... Figure 6 The state shown; Next, pinch the handle 22 and rotate it around the first hinge axis 24. During the rotation, pull the pull rope 232 to move it in the connecting sleeve 231. The pull rope 232 being pulled will drive the first clamping plate 41 to rotate around the second hinge axis 44 towards the second clamping plate 42 until the first clamping plate 41 and the second clamping plate 42 stably clamp the cassava stalk. After that, you need to continue to pinch the handle 22. Finally in Figure 6 From the perspective shown, the farmer can step on one of the rollers 31 with one foot to prevent the roller 31 from rotating during the subsequent pulling process. Then, the telescopic mechanism 1 is rotated clockwise to make the entire device rotate clockwise around the connecting rod 32. During this process, the first clamping plate 41 and the second clamping plate 42 will drive the cassava stalks and the cassava tubers growing underground to be pulled out of the ground.
