Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping mechanism technology, and in particular to a clamping mechanism for hand-held agricultural machinery. Background Technology
[0002] The clamping mechanism of hand-held agricultural machinery is a mechanical device used to stably clamp crops during operation to assist in harvesting, picking, and transportation. Its core function is to fix crops with physical clamping force to prevent them from falling off or being damaged due to mechanical movement, while ensuring operational accuracy and efficiency.
[0003] When using the clamping mechanism of a hand-held seedling planter to plant seedlings, the conical clamping mechanism not only needs to clamp and fix the seedlings, but also needs to be inserted into the soil to create planting holes. The seedlings are then placed in the planting holes. However, the soil is not always flat. When the clamping mechanism is digging holes on some sloping soil, it is easy to become crooked, which will cause the seedlings to become crooked. Some crooked seedlings may even be buried in the soil, which is not conducive to the normal growth of the seedlings. Utility Model Content
[0004] This utility model is a clamping mechanism for hand-held agricultural machinery that is proposed to solve the problem that when the clamping mechanism is used to dig holes on sloping land, it is easy to become skewed, which will cause the seedlings to become skewed, and some skewed seedlings may even be buried in the soil, which will not be conducive to the normal growth of the seedlings.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a clamping mechanism for hand-held agricultural machinery, comprising a ring, extension blocks symmetrically fixedly installed on the outer surface of the ring, two semi-conical cylinders rotatably installed on one side of the two extension blocks, a common connecting frame fixedly installed on the top of the two extension blocks, a first sliding rod and a second sliding rod slidably installed on the outer surface of the connecting frame, an elastic element fixedly installed on the outer surface of the second sliding rod, a fixing rod fixedly installed at one end of the elastic element, the fixing rod being fixed to the outer surface of the connecting frame, steel cables symmetrically fixedly installed on both sides of the first sliding rod and the second sliding rod, one end of the steel cables being fixedly installed on the outer surface of the semi-conical cylinders, and an auxiliary device provided at the bottom of the two semi-conical cylinders, the auxiliary device limiting the two semi-conical cylinders by setting a base plate capable of vertically positioning the two semi-conical cylinders and the ground.
[0006] The effect achieved by the above components is as follows: by setting a base plate, the base plate and the two semi-conical tubes are always kept perpendicular. When the base plate is in contact with the ground, it can be ensured that the two semi-conical tubes are always kept perpendicular to the ground when inserted into the soil. This helps to prevent the clamping mechanism from tilting when digging holes on some sloping land, thus preventing the seedlings from tilting and facilitating the normal growth of the seedlings.
[0007] Preferably, the auxiliary device includes a base plate disposed at the bottom of the two semi-conical cylinders, the bottom of the base plate having a through hole, and round rods symmetrically fixedly installed at the top of the base plate, the round rods being slidably installed on the inner wall of the extension block.
[0008] The effect achieved by the above components is as follows: after the base plate is placed on the ground, the two semi-conical tubes are then squeezed. Since the base plate is always in contact with the ground, and the conical tubes are always perpendicular to the base plate when inserted into the ground, the conical tubes can remain perpendicular to the ground. At the same time, when the two semi-conical tubes are squeezed, so that they pass through the through holes on the base plate and enter the ground, the round rod will slide synchronously on the inner wall of the extension block, which can limit the two semi-conical tubes. Thus, when the two semi-conical tubes are planted, the semi-conical tubes can be used to be perpendicular to the ground, thereby enabling vertical planting of seedlings.
[0009] Preferably, a spring is fitted on the outer surface of the round rod, and the two ends of the spring are respectively fixedly installed on one side of the extension block and the base plate.
[0010] The effect achieved by the above components is as follows: by setting springs, when the two semi-conical cylinders are pushed down, the base plate will compress the springs, causing the springs to deform. When the two semi-conical cylinders are pulled out of the ground, the springs will reset and drive the base plate to the bottom of the two semi-conical cylinders, thus making it easier to use the clamping mechanism repeatedly.
[0011] Preferably, a rectangular tube is symmetrically installed on the top of the base plate, the rectangular tube is located on one side of the spring, a rectangular plate is slidably installed on the inner wall of the rectangular tube, and one end of the rectangular plate is fixedly installed on the bottom of the extension block.
[0012] The effect achieved by the above components is as follows: by setting up rectangular plates and rectangular tubes, when the two semi-conical tubes are pushed into the ground and the spring is squeezed, the rectangular plates will also slide on the inner wall of the rectangular tubes, and the round rods will slide synchronously on the inner wall of the extension blocks. Under the combined action of the rectangular plates, rectangular tubes and round rods, the base plate can be guided, so that the base plate can always be perpendicular to the ground.
[0013] Preferably, a bolt is threaded into one side of the rectangular tube.
[0014] The effect achieved by the above components is as follows: by rotating the bolt, one end of the bolt abuts against one side of the rectangular plate, the bolt can fix the rectangular plate and the rectangular tube, thereby fixing the base plate. This makes it easier to fix the base plate in a suitable position when it is not needed, and makes it easier to use the clamping mechanism.
[0015] Preferably, a rubber strip is adhered to the inner wall of one side of the rectangular plate, and the bolt is located on one side of the rubber strip.
[0016] The effect achieved by the above components is that by setting the rubber strip, one side of the rectangular plate can be replaced to abut against one end of the bolt, and the friction between the bolt and the rectangular plate can be increased, making the bolt more secure in fixing the rectangular plate and the rectangular tube.
[0017] Preferably, a rubber pad is inserted into the inner wall of the base plate, and the rubber pad has a hollow structure.
[0018] The effect achieved by the above components is as follows: by setting a hollow rubber pad, when the clamping mechanism is not needed, the rubber pad is inserted into the inner wall of the base plate. At this time, the two semi-conical cylinders are set on one side of the rubber pad, and the rubber pad and the base plate can play a certain role in protecting one end of the two semi-conical cylinders, which helps to prevent the semi-conical cylinders from hitting hard objects and causing damage to the semi-conical cylinders.
[0019] Preferably, L-shaped clips are symmetrically fixedly installed on the top of the rubber pad. The L-shaped clips are made of rubber and are engaged with the inner wall of the base plate.
[0020] The effect achieved by the above components is as follows: when the rubber pad is inserted into the inner wall of the base plate and the two L-shaped blocks abut against the inner wall of the base plate, the rubber pad and the inner wall of the base plate can be fixed, which helps to prevent the rubber pad from easily detaching from the base plate, and also makes it easy to disassemble the rubber pad.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting a base plate that is always perpendicular to the two semi-conical tubes, when the base plate comes into contact with the ground, it can be ensured that the two semi-conical tubes remain perpendicular to the ground when inserted into the soil. This helps to prevent the clamping mechanism from tilting when digging holes on sloping land, thus preventing the seedlings from tilting and facilitating their normal growth.

Detailed Implementation
[0028] Example 1, referring to Figures 1-3 As shown, this embodiment discloses a clamping mechanism for hand-held agricultural machinery, including a ring 1. Extension blocks 3 are symmetrically fixedly mounted on the outer surface of the ring 1. Two semi-conical cylinders 4 are rotatably mounted on one side of each extension block 3. A common connecting frame 5 is fixedly mounted on the top of each extension block 3. A first sliding rod 6 and a second sliding rod 7 are slidably mounted on the outer surface of the connecting frame 5. An elastic element 8 is fixedly mounted on the outer surface of the second sliding rod 7. A fixing rod 10 is fixedly mounted on one end of the elastic element 8 and fixed to the outer surface of the connecting frame 5. Steel cables 9 are symmetrically fixedly mounted on both sides of the first sliding rod 6 and the second sliding rod 7. One end of the cable 9 is fixedly installed on the outer surface of the semi-cone 4. An auxiliary device 2 is provided at the bottom of the two semi-cone 4. The auxiliary device 2 limits the two semi-cone 4 by setting a base plate 21 that can vertically position the two semi-cone 4 and the ground. By setting the base plate 21, the base plate 21 and the two semi-cone 4 are always perpendicular. Therefore, when the base plate 21 is in contact with the ground, it can be ensured that the two semi-cone 4 are always perpendicular to the ground when inserted into the ground. This helps to prevent the clamping mechanism from tilting when digging holes on some sloping land, thus preventing the seedlings from tilting and facilitating the normal growth of the seedlings.
[0029] Reference Figure 2 and Figure 3As shown, the auxiliary device 2 includes a base plate 21, which is located at the bottom of the two semi-conical cylinders 4. The bottom of the base plate 21 has a through hole, and round rods 23 are symmetrically fixed to the top of the base plate 21. The round rods 23 are slidably mounted on the inner wall of the extension block 3. After the base plate 21 is placed on the ground, the two semi-conical cylinders 4 are then pressed. Since the base plate 21 is always in contact with the ground, and the conical cylinders remain perpendicular to the base plate 21 when inserted into the ground, the conical cylinders can remain perpendicular to the ground. Simultaneously, when the two semi-conical cylinders 4 are pressed, causing them to pass through the through hole on the base plate 21 and enter the ground, the round rods 23 will slide synchronously on the inner wall of the extension block 3, thus limiting the movement of the two semi-conical cylinders 4. When planting with two semi-conical tubes 4, the semi-conical tubes 4 can be used perpendicular to the ground, thus enabling vertical planting of seedlings. A spring 22 is fitted on the outer surface of the round rod 23. The two ends of the spring 22 are respectively fixedly installed on one side of the extension block 3 and the base plate 21. A round block 28 is fixedly installed on one end of the round rod 23. By setting the spring 22, when the two semi-conical tubes 4 are pushed down, the base plate 21 will squeeze the spring 22, causing the spring 22 to deform. When the two semi-conical tubes 4 are pulled out of the ground, the spring 22 will reset and drive the base plate 21 to move to the bottom of the two semi-conical tubes 4, thus making it easier to use the clamping mechanism repeatedly. At the same time, by setting the round block 28, one end of the round rod 23 can be blocked, which helps to prevent the round rod 23 from detaching from the inner wall of the extension block.
[0030] Reference Figure 2 and Figure 3 As shown, rectangular tubes 25 are symmetrically installed on the top of the base plate 21. The rectangular tubes 25 are positioned on one side of the spring 22. A rectangular plate 24 is slidably installed on the inner wall of the rectangular tube 25. One end of the rectangular plate 24 is fixedly installed on the bottom of the extension block 3. By setting up the rectangular plate 24 and the rectangular tube 25, when the two semi-conical tubes 4 are pushed into the ground to compress the spring 22, the rectangular plate 24 will also slide on the inner wall of the rectangular tube 25, and the round rod 23 will slide synchronously on the inner wall of the extension block 3. The combined action of rod 5 and round rod 23 guides the base plate 21, ensuring that the base plate 21 is always perpendicular to the ground. A bolt 26 is threaded into one side of the rectangular tube 25. By rotating the bolt 26, one end of the bolt 26 abuts against one side of the rectangular plate 24, thus fixing the rectangular plate 24 and the rectangular tube 25 together, and consequently fixing the base plate 21. This makes it easier to fix the base plate 21 in a suitable position when it is not needed, and also facilitates the use of the clamping mechanism.
[0031] Reference Figure 2 and Figure 4As shown, a rubber strip 27 is bonded to the inner wall of one side of the rectangular plate 24, and a bolt 26 is set on one side of the rubber strip 27. By setting the rubber strip 27, one side of the rectangular plate 24 can be replaced to abut against one end of the bolt 26, and the friction between the bolt 26 and the rectangular plate 24 can be increased, making the bolt 26 more secure in fixing the rectangular plate 24 and the rectangular tube 25.
[0032] Reference Figure 2 and Figure 4 As shown, a rubber pad 29 is inserted into the inner wall of the base plate 21. The rubber pad 29 has a hollow structure. By setting the hollow rubber pad 29, when the clamping mechanism is not needed, the rubber pad 29 is inserted into the inner wall of the base plate 21. At this time, the two semi-conical cylinders 4 are placed on one side of the rubber pad 29. The rubber pad 29 and the base plate 21 can provide a certain protection for one end of the two semi-conical cylinders 4, which helps to prevent the semi-conical cylinders 4 from hitting hard objects and causing damage. The top of the rubber pad 29 is symmetrically fixed with L-shaped locking blocks 210. The L-shaped locking blocks 210 are made of rubber and are engaged with the inner wall of the base plate 21. When the rubber pad 29 is inserted into the inner wall of the base plate 21 and the two L-shaped locking blocks 210 abut against the inner wall of the base plate 21, the rubber pad 29 and the inner wall of the base plate 21 can be fixed together, which helps to prevent the rubber pad 29 from easily detaching from the base plate 21 and also facilitates the disassembly of the rubber pad 29.
[0033] Working principle: After the base plate 21 is placed on the ground, the two semi-conical cylinders 4 are pressed. Since the base plate 21 is always in contact with the ground, and the conical cylinders remain perpendicular to the base plate 21 when inserted into the ground, the conical cylinders can maintain perpendicularity to the ground. At the same time, when the two semi-conical cylinders 4 are pressed, they pass through the through holes on the base plate 21 and enter the ground. This causes the round rod 23 to slide synchronously on the inner wall of the extension block 3, and also causes the rectangular plate 24 to slide synchronously on the inner wall of the rectangular cylinder 25. Simultaneously, the base plate 21 also presses the spring 22, causing the spring 22 to deform. The base plate 21 can limit the movement of the two semi-conical cylinders 4. Since the base plate 21 and the two semi-conical cylinders 4 are always perpendicular, when the base plate 21 is in contact with the ground, it can ensure that the two semi-conical cylinders 4 remain perpendicular to the ground when inserted into the ground. The vertical planting of seedlings is possible. After the two semi-conical tubes 4 are pulled out of the soil, the spring 22 will reset and move the base plate 21 to the bottom of the two semi-conical tubes 4. The rubber pad 29 is inserted into the inner wall of the base plate 21, and the rubber pad 29 is fixed to the inner wall of the base plate 21 by the two L-shaped blocks 210. At this time, the rubber pad 29 and the base plate 21 can provide a certain protection for one end of the two semi-conical tubes 4, which helps to prevent the semi-conical tubes 4 from hitting hard objects and causing damage. The bolt 26 is rotated so that one end of the bolt 26 abuts against the rubber strip 27 on one side of the rectangular plate 24. The bolt 26 can fix the rectangular plate 24 and the rectangular tube 25, and thus fix the base plate 21. This helps to prevent the rubber pad 29 and the base plate 21 from easily shifting and affecting the protection of the two semi-conical tubes 4.
