Description
Technical Field
[0001] The utility model relates to the technical field of fruit tree branch pulling devices, in particular to a fruit tree branch pulling device. Background Art
[0002] In the growth and breeding of fruit trees such as apples, walnuts, cherries, pears, peaches, chestnuts, plums, and persimmons, in order to increase the light-receiving and ventilation areas of branches and leaves and improve the yield, it is necessary to shape the newly growing branches each year through methods such as branch pulling, branch pressing, and pruning. Branch pulling is a common method for fruit tree shaping.
[0003] During the process of using the current fruit tree branch pulling device, workers often find that the current branch pulling method is to force most of a wooden wedge into the ground, tie a string to the part on the ground, and tie the other end to the branch that needs to be pulled. Since the number of branches that need to be pulled is relatively large, the corresponding number of wooden wedges to be installed will increase. A large number of wooden wedges installed on the ground will become a tripping hazard, especially at night or in poor visibility conditions, which is likely to increase the risk of pedestrians getting injured. Content of the Utility Model
[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a fruit tree branch pulling device.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a fruit tree branch pulling device includes a plurality of pulling ropes. Hooks are fixedly connected to the pulling ropes. Adjusting columns are arranged on the pulling ropes. A clamping structure is jointly arranged on the plurality of adjusting columns. The clamping structure is mainly composed of a first clamping block. The first clamping block is arranged on the adjusting column. A second clamping block is arranged on the first clamping block. Two fixing ears are respectively and fixedly connected to the first clamping block and the second clamping block. A round rod is slidably connected to the two fixing ears.
[0006] The effects achieved by the above components are as follows: Slide the first clamping block away from the round rod, then pass the tree trunk through the space between the first clamping block and the second clamping block, and then slide the first clamping block and the second clamping block closer to each other so that the first clamping block and the second clamping block jointly clamp the tree trunk. Then hang a plurality of hooks on the branches that need to be pulled down, and there is no need to drive a large number of wooden wedges into the ground, thus avoiding the situation that a large number of wooden wedges installed on the ground will become a tripping hazard, especially at night or in poor visibility conditions, which is likely to increase the risk of pedestrians getting injured.
[0007] Preferably, a bidirectional screw rod is jointly threadedly connected to the two fixing ears, and the two threaded sections on the bidirectional screw rod have opposite thread directions.
[0008] The effects achieved by the above components are as follows: Since the first clamping block and the second clamping block are limited and slide on the round rod, rotating the bidirectional screw can drive the first clamping block and the second clamping block to slide synchronously and in opposite directions, making the clamping more stable.
[0009] Preferably, a crank is fixedly connected to the bidirectional screw, and a plurality of air bags are fixedly connected to both the first clamping block and the second clamping block.
[0010] The effects achieved by the above components are as follows: The staff can drive the bidirectional screw to rotate by manually rotating the crank, and during the clamping process, the air bags deform to better fit the surface of the tree trunk, so as to improve the clamping effect.
[0011] Preferably, an adjusting structure is jointly arranged on the first clamping block and the second clamping block. The adjusting structure mainly consists of two adjusting grooves, which are respectively opened on the first clamping block and the second clamping block, and the adjusting grooves are slidably connected with a plurality of adjusting columns.
[0012] The effects achieved by the above components are as follows: The staff can change the position and direction of the branch pulling by sliding the adjusting column.
[0013] Preferably, a winding disc is rotatably connected to the adjusting column, a fixing rod is fixedly connected to the winding disc, and the winding disc is fixedly connected with the pulling rope.
[0014] The effects achieved by the above components are as follows: The staff can manually rotate the fixing rod to drive the winding disc to rotate, so that the pulling rope is wound on the winding disc, and the length of the pulling rope can be changed to cope with different branch pulling situations.
[0015] Preferably, a T-shaped plate is fixedly connected to the adjusting column, and a threaded bolt is threadedly connected to the T-shaped plate.
[0016] The effects achieved by the above components are as follows: After the position of the adjusting column is adjusted, rotate the threaded bolt so that the threaded bolt abuts against the first clamping block or the second clamping block, and then the T-shaped plate can be limited, and further the adjusting column can be limited.
[0017] Preferably, a plurality of circular grooves are opened on the winding disc, and a sliding rod is slidably inserted into the T-shaped plate.
[0018] The effects achieved by the above components are as follows: When the pulling rope is wound to the specified length, slide the sliding rod so that the sliding rod is stuck in the corresponding circular groove, and the winding disc can be limited to prevent the winding disc from rotating during the branch pulling process.
[0019] Preferably, a spring is sleeved on the sliding rod, one end of the spring is fixedly connected to the sliding rod, and the other end of the spring is fixedly connected to the T-shaped plate.
[0020] The effects achieved by the above components are as follows: When the sliding rod is stuck into the circular groove, the spring is in a stretched state. Therefore, the resilience of the spring acts on the sliding rod, making the limit more stable.
[0021] Compared with the prior art, the advantages and positive effects of the present utility model are that in the present utility model, by setting a clamping structure, the first clamping block is slid away from the round rod, and then the tree trunk is passed through between the first clamping block and the second clamping block. Then, the first clamping block and the second clamping block are slid closer to each other, so that the first clamping block and the second clamping block jointly clamp on the tree trunk to clamp the tree trunk. Then, a number of hooks are hung on the branches that need to be pulled down, and there is no need to drive a large number of wooden wedges into the ground. Since the first clamping block and the second clamping block are limited and slide on the round rod, rotating the bidirectional screw can drive the first clamping block and the second clamping block to slide synchronously and in opposite directions, making the clamping more stable. The staff can drive the bidirectional screw to rotate by manually rotating the crank, and during the clamping process, the airbag deforms to better fit the surface of the tree trunk to improve the clamping effect, thus avoiding the situation that a large number of wooden wedges installed on the ground will become a tripping hazard, especially at night or in poor visibility conditions, which is likely to increase the risk of pedestrian injury.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0027] Embodiment 1, as Figure 1 and Figure 2 shown, a fruit tree branch pulling device includes a number of pulling ropes 1, hooks 2 are fixedly connected to the pulling ropes 1, and adjusting columns 3 are arranged on the pulling ropes 1.
[0028] Refer to Figure 1 and Figure 2 On several adjusting columns 3, a clamping structure 4 is jointly arranged. The clamping structure 4 is mainly composed of a first clamping block 41. The first clamping block 41 is arranged on the adjusting column 3. A second clamping block 42 is arranged on the first clamping block 41. Two fixing ears 43 are respectively and fixedly connected to the first clamping block 41 and the second clamping block 42. A round rod 44 is jointly and slidably connected to the two fixing ears 43. Slide the first clamping block 41 away from the round rod 44, then pass the tree trunk through between the first clamping block 41 and the second clamping block 42, and then slide the first clamping block 41 and the second clamping block 42 closer to each other so that the first clamping block 41 and the second clamping block 42 jointly clamp the tree trunk. After clamping the tree trunk, hang several hooks 2 on the branches that need to be pulled down, and there is no need to drive a large number of wooden wedges into the ground. Thus, it avoids the situation that a large number of wooden wedges installed on the ground will become a tripping hazard, especially at night or in poor visibility conditions, which is likely to increase the risk of pedestrian injury. A bidirectional screw rod 45 is jointly and threadedly connected to the two fixing ears 43. The two sections of the thread on the bidirectional screw rod 45 have opposite directions. Since the first clamping block 41 and the second clamping block 42 are limited and slide on the round rod 44, rotating the bidirectional screw rod 45 can drive the first clamping block 41 and the second clamping block 42 to slide synchronously and in opposite directions, making the clamping more stable. A crank 46 is fixedly connected to the bidirectional screw rod 45. A number of air bags 47 are fixedly connected to both the first clamping block 41 and the second clamping block 42. The staff can drive the bidirectional screw rod 45 to rotate by manually rotating the crank 46, and during the clamping process, the air bags 47 deform to better fit the surface of the tree trunk to improve the clamping effect.
[0029] Refer to Figure 3 and Figure 4, an adjusting structure 5 is jointly arranged on the first clamping block 41 and the second clamping block 42. The adjusting structure 5 mainly consists of two adjusting grooves 51. The two adjusting grooves 51 are respectively opened on the first clamping block 41 and the second clamping block 42. The adjusting grooves 51 are slidably connected with a plurality of adjusting columns 3. The staff can change the position and direction of branch pulling by sliding the adjusting columns 3. A winding disc 52 is rotatably connected to the adjusting columns 3. A fixing rod 53 is fixedly connected to the winding disc 52. The winding disc 52 is fixedly connected with the pulling rope 1. The staff can manually rotate the fixing rod 53 to drive the winding disc 52 to rotate, so that the pulling rope 1 is wound around the winding disc 52, and the length of the pulling rope 1 can be changed to cope with different branch pulling situations. A T-shaped plate 54 is fixedly connected to the adjusting columns 3. A threaded bolt 55 is threadedly connected to the T-shaped plate 54. After the position of the adjusting columns 3 is adjusted, rotate the threaded bolt 55 so that the threaded bolt 55 abuts against the first clamping block 41 or the second clamping block 42, thereby limiting the T-shaped plate 54 and further limiting the adjusting columns 3. A plurality of circular grooves 56 are opened on the winding disc 52. A sliding rod 57 is slidably inserted into the T-shaped plate 54. When the pulling rope 1 is wound to a specified length, slide the sliding rod 57 so that the sliding rod 57 is stuck into the corresponding circular groove 56, which can limit the winding disc 52 and prevent the winding disc 52 from rotating during the branch pulling process. A spring 58 is sleeved on the sliding rod 57. One end of the spring 58 is fixedly connected to the sliding rod 57, and the other end of the spring 58 is fixedly connected to the T-shaped plate 54. When the sliding rod 57 is stuck into the circular groove 56, the spring 58 is in a stretched state. Therefore, the resilient force of the spring 58 acts on the sliding rod 57, making the limit more stable.
[0030] Working principle: Slide the first clamping block 41 away from the round rod 44, then pass the tree trunk through between the first clamping block 41 and the second clamping block 42, and then slide the first clamping block 41 and the second clamping block 42 closer to each other so that the first clamping block 41 and the second clamping block 42 jointly clamp the tree trunk. Hang several hooks 2 on the branches that need to be pulled down, then there is no need to drive a large number of wooden wedges into the ground, thus avoiding the situation that a large number of wooden wedges installed on the ground will become tripping hazards, especially at night or in poor visibility conditions, which is likely to increase the risk of pedestrian injury. Since the first clamping block 41 and the second clamping block 42 are limited and slide on the round rod 44, rotating the bidirectional screw rod 45 can drive the first clamping block 41 and the second clamping block 42 to slide synchronously and in opposite directions, making the clamping more stable. The staff can drive the bidirectional screw rod 45 to rotate by manually rotating the crank 46, and during the clamping process, the airbag 47 deforms to better fit the surface of the tree trunk to improve the clamping effect. The staff can change the position and direction of the branch pulling by sliding the adjusting column 3. The staff can manually rotate the fixed rod 53 to drive the winding disc 52 to rotate, so that the pulling rope 1 is wound around the winding disc 52, and the length of the pulling rope 1 can be changed to cope with different branch pulling situations. After the position of the adjusting column 3 is adjusted, rotate the threaded bolt 55 so that the threaded bolt 55 abuts against the first clamping block 41 or the second clamping block 42, and then the T-shaped plate 54 can be limited, and further the adjusting column 3 can be limited. When the pulling rope 1 is wound to the specified length, slide the sliding rod 57 so that the sliding rod 57 is stuck into the corresponding circular groove 56 to limit the winding disc 52 and prevent the winding disc 52 from rotating during the branch pulling process. When the sliding rod 57 is stuck into the circular groove 56, the spring 58 is in a stretched state, so the elastic force of the spring 58 acts on the sliding rod 57 to make the limit more stable.
