DETAILED DESCRIPTION

[0018] The utility model is further described below.

[0019] The utility model provides a puncher, which is mainly used for drilling holes for planting seedlings, and comprises a gripping rod 1, a vertical rod 2, a punching sleeve 3 and a cross bar 4; the gripping rod 1 is vertically arranged at one end of the vertical rod, the cross bar 4 is vertically arranged at the other end of the vertical rod, the gripping rod 1, the vertical rod 2 and the cross bar 4 form an I-shape, and a plurality of the punching sleeves 3 are arranged at intervals on one side of the cross bar 4; each of the punching sleeves 3 is fixedly provided with a sliding mechanism 5 that slides along the length direction of the cross bar 4 on a side close to the cross bar 4, the sliding mechanism 5 comprises a sliding sleeve 51, the sliding sleeve 51 is sleeved on the cross bar 4, a fixing hole 53 is opened on the side of the sliding sleeve 51 away from the punching sleeve 3, a locking mechanism 6 for locking the sliding mechanism 5 is arranged in the fixing hole 53; a positioner 7 is provided on the punching sleeve 3 located at the end of the cross bar 4.

[0020] like Figure 1 , Figure 2As shown, the puncher includes a grip rod 1, a vertical rod 2, and a cross rod 4 arranged in an I-shape. Multiple punching sleeves 3 are provided on one side of the cross rod 4. The punching sleeve 3 can adopt the punching tube structure described in CN205847914U "Soil Puncher", or can also adopt the existing cylindrical punching tube structure. When using the puncher, one can step on the cross rod 4 to insert the punching sleeve 3 into the soil body. In this way, the operator can press down the puncher without bending over. When it is necessary to take out the puncher from the soil body, hold the grip rod 1 and lift it upwards to achieve the purpose of taking out the puncher. Moreover, the setting of the cross rod 4 can further limit the hole depth of the planting holes drilled by the punching sleeve 3. That is, when the cross rod 4 is in contact with the ground, a large resistance will be generated, and at this time, stopping stepping can control the hole depth of the drilled planting holes. To facilitate adjusting the position of the punching sleeve 3 on the cross rod 4, that is, to adjust the distance between the punching sleeves 3 on the cross rod 4 according to the required planting spacing of different seedlings, a sliding mechanism 5 that can slide along the length direction of the cross rod 4 is provided on the cross rod 4, and then the punching sleeve 3 is welded to one side of the sliding mechanism 5. Welding can ensure the connection stability between the punching sleeve 3 and the sliding mechanism 5. Specifically, such as Figure 1 、 Figure 2As shown in the figure, the sliding mechanism 5 includes a sliding sleeve 51. The sliding sleeve 51 can be a square steel sleeve with a hollow interior and an inner diameter adapted to the cross-section of the cross bar 4, which can be an existing one. To facilitate the sliding of the sliding sleeve 51 along the length direction of the cross bar 4 without being affected by the vertical bar 2, a strip-shaped hole for the vertical bar 2 to pass through is provided on the sliding sleeve 51. When sliding to the connection between the cross bar 4 and the vertical bar 2, the vertical bar 2 can pass through the strip-shaped hole. A fixing hole 53 is provided on the side of the sliding sleeve 51 facing away from the punching sleeve 3. The locking mechanism 6 is installed in the fixing hole 53. The locking mechanism 6 can be a bolt or an abutting block. Inserting it into the fixing hole 53 and abutting against the cross bar 4 can fix the sliding sleeve 51. A sliding sleeve 51 is provided on each punching sleeve 3 arranged on the cross bar 4, and each sliding sleeve 51 can slide along the length direction of the cross bar 4. Construction workers can slide the sliding sleeve 51 on the cross bar 4 according to the actual spacing of the planting holes required for the seedlings, so as to adjust the spacing between the punching sleeves 3. By setting the locking mechanism 6 in the fixing hole 53 provided on the sliding sleeve 51, the position of the punching sleeve 3 can be fixed, thus achieving adjustable punching spacing of the puncher, which can be applicable to different planting spacings required for different seedlings. And because the sliding sleeve 51 is sleeved on the cross bar 4, construction workers can also increase or decrease the number of punching sleeves 3 on the cross bar 4 according to actual needs, that is, sliding the sliding sleeve 51 out of the cross bar 4 or installing it on the cross bar 4. To ensure that the punching spacing is always the same when using this puncher to continuously drill planting holes, a positioner 7 is provided on the punching sleeve 3 at the end of the cross bar 4. The positioner 7 can be directly welded to the side wall of the punching sleeve 3. To facilitate the disassembly and storage of the puncher, the positioner 7 can also be arranged on the side wall of the punching sleeve 3 in a detachable manner such as plugging or bolt connection. The positioner 7 can be an existing measuring scale or an existing telescopic rod. After determining the spacing, fix the length of the telescopic rod. When drilling, align the end of the telescopic rod with the already drilled planting hole, and step on the cross bar 4 to ensure that the spacing of the continuously drilled planting holes remains consistent without wasting the drilled hole positions. Using this puncher, by providing a sliding sleeve 51 slidably connected to the cross bar 4 on the punching sleeve 3, the spacing between the punching sleeves 3 can be adjusted. Then, use the locking mechanism 6 to pass through the fixing hole 53 provided on the sliding sleeve 51 to lock the sliding mechanism 5, so as to fix the position of the punching sleeve 3, and then realize the adjustment of the punching plant spacing, so as to meet the needs of different seedlings for punching spacing without replacing the puncher, improve the punching efficiency, and there is also a positioner, which can help ensure the accuracy of the continuous punching plant spacing. And this puncher is simple to manufacture and convenient to install, which can effectively reduce the cost of manufacturing the puncher.

[0021] Specifically, to ensure the tight fit between the locking mechanism 6 and the sliding sleeve 51 and prevent the locking mechanism 6 from falling off during the use of the puncher, which may cause the sliding sleeve 51 to slide and change the punching distance; the above-mentioned locking mechanism 6 can adopt the structure as shown in Figure 1 . The locking mechanism 6 includes a nut 61 and a threaded rod 62 threadedly connected to the nut 61. The nut 61 is welded to the outside of the fixing hole 53. The central hole of the nut 61 corresponds to the fixing hole 53. The threaded rod 62 sequentially passes through the nut 61 and the fixing hole 53 and abuts against the cross bar 4. By using the nut 61 welded to the outside of the fixing hole 53 and threadedly connecting it with the threaded rod 62, it can not only ensure that the threaded rod 62 can extend into the sliding sleeve 51 and abut against the cross bar 4, but also ensure that during the use of the puncher, due to the limiting and fixing effect of the nut 61, the threaded rod 62 always maintains the state of abutting against the cross bar 4 and will not slip off, ensuring the consistency of the punching distance.

[0022] To save the installation steps, the fixing hole 53 is a threaded hole, and the locking mechanism 6 is a threaded rod 62 adapted to the threaded hole. The threaded rod 62 passes through the threaded hole and abuts against the cross bar 4. By directly designing the fixing hole 53 as a threaded hole, there is no need to install the nut 61 anymore. The threaded connection between the threaded rod 62 and the fixing hole 53 can achieve the locking effect on the sliding sleeve 51, and ensure that the threaded rod 62 will not slip off during the use of the puncher, ensuring the consistency of the punching distance.

[0023] To ensure that the continuously drilled seedling planting holes are located on the same straight line and have equal spacing, it is necessary to place the adjacent two punching sleeves 3 at the end of the cross bar 4, that is, the punching sleeves 3 close to the already drilled seedling planting holes, into the previously drilled seedling planting holes, which will waste the drilling of two seedling planting holes and the drilling efficiency is relatively low. To improve the punching efficiency, as shown in Figure 1 、 Figure 2As shown, the positioner 7 includes an extension rod 71, a first positioning vertical rod 72 and a second positioning vertical rod 73. The extension rod 71 is arranged along the length direction of the cross bar 4 at the end of the perforating sleeve 3 away from the cross bar 4. The first positioning vertical rod 72 and the second positioning vertical rod 73 are arranged on the extension rod 71 at intervals along the length direction of the extension rod 71. The first positioning vertical rod 72 and the second positioning vertical rod 73 are both vertically arranged on the extension rod 71 and parallel to the perforating sleeve 3. The spacing between the first positioning vertical rod 72 and the adjacent perforating sleeve 3 is equal to the spacing between the first positioning vertical rod 72 and the second positioning vertical rod 73. A locator 7 is provided on one side of the perforated sleeve 3 located at the end of the cross bar 4, and the locator 7 is used to ensure that the drilled seedling holes are located in the same straight line and the intervals are equal. Specifically, the first positioning vertical rod 72 and the second positioning vertical rod 73 are aligned with the two seedling holes drilled previously one by one. According to the principle of "two points determine a straight line", at this time, the perforated sleeve 3 which is always located in the same straight line with the first positioning vertical rod 72 and the second positioning vertical rod 73 is also located in the same straight line with the seedling holes drilled previously, and because the first positioning vertical rod 72 and the seedling holes are aligned with each other, the first positioning vertical rod 72 and the seedling holes are aligned with each other. The spacing between the seedling holes is equal to the spacing between the first positioning vertical rod 72 and the second positioning vertical rod 73, that is, the position of the punching sleeve 3 is equal to the spacing of the previously drilled seedling holes corresponding to the first positioning vertical rod 72 and the second positioning vertical rod 73. Such a setting can realize the equal spacing of the seedling holes without the need for advance dotting and positioning, and the holes are always located in the same straight line. There is no need for the operator to repeatedly measure the distance and pull the wire to mark points to ensure the spacing between the seedling holes and whether the seedling holes are located in the same straight line, thereby saving punching time and improving punching efficiency.

[0024] The positioner 7 and the perforated sleeve 3 can be connected by welding or detachable connection. For easy disassembly and storage, the positioner 7 can be detachably arranged on the perforated sleeve 3. The detachable connection can be specifically connected by plugging or bolting. As a specific implementation method, Figure 1 , Figure 2As shown, a positioning nut 74 is fixedly arranged on the side of the punching sleeve 3 at the end of the cross bar 4. One end of the extension rod 71 close to the punching sleeve 3 is a threaded section 711. The threaded section 711 is threadedly connected with the positioning nut 74. A back-tightening nut 75 is threadedly connected on the threaded section 711. The back-tightening nut 75 is located between the positioning nut 74 and the first positioning vertical rod 72. By fixedly arranging a positioning nut 74 on the side of the punching sleeve 3 at the end of the cross bar 4 and setting one end of the extension rod 71 close to the baffle 41 as the threaded section 711, the detachable connection between the extension rod 71 and the punching sleeve 3 is realized through threaded connection, which is simple to manufacture and low in cost. A back-tightening nut 75 is added to the extension rod 71 to further fix the extension rod 71 and prevent the extension rod 71 from loosening. Since it is necessary to go to the storage room to take out the positioner 7 every time it is needed, a fixing nut threadedly connected with the threaded section 711 can be arranged on the vertical rod 2. When the positioner 7 is not in use, the positioner 7 can be arranged on the fixing nut for storage.

[0025] To facilitate the adjustment of the positions of the first positioning vertical rod 72 and the second positioning vertical rod 73 on the positioner 7 so that the distance between them is consistent with the required distance of the seedling planting holes to be drilled, reduce the number of times of replacing the positioner 7, and improve the drilling efficiency, the first positioning vertical rod 72 and the second positioning vertical rod 73 are slidably arranged on the extension rod 71. Specifically, the connection mode between the first positioning vertical rod 72 and the second positioning vertical rod 73 and the extension rod 71 can adopt the chute-guide connection mode. A guide rail is arranged on the extension rod 71, and chutes slidably connected with the guide rail are arranged on the first positioning vertical rod 72 and the second positioning vertical rod 73. Or the whole extension rod 71 is set as a screw rod, and rotating nuts adapted to the screw rod are rotatably arranged on the first positioning vertical rod 72 and the second positioning vertical rod 73. By moving the positions of the first positioning vertical rod 72 and the second positioning vertical rod 73 on the extension rod, the adjustment of the distance between the first positioning vertical rod 72 and the second positioning vertical rod 73 can be realized without disassembling and replacing the positioner 7 to adapt to the required distances of different seedling plants and improve the drilling efficiency.

[0026] To prevent the cross bar 4 from deforming due to stepping on the cross bar 4, such as Figure 1 、 Figure 2As shown, a pedal 42 is also provided on the cross bar 4, and the pedal 42 is arranged on the side of the cross bar 4 away from the perforating sleeve 3 and below the vertical bar 2; the pedal 42 can be made of existing steel plates or square steel pipes arranged at intervals, so that the operator only needs to step on the pedal 42 to press the perforating sleeve 3 into the soil without bending over, thereby reducing the labor intensity of the operator; and the pedal 42 is provided to facilitate the construction workers to step on it, and it can also play a role of limiting; after the pedal 42 is provided, the sliding mechanism 5 can slide on the left and right sides of the cross bar 4 after the pedal 42 is provided; if the sliding mechanism 5 is to slide on the entire cross bar 4, a long hole for the pedal 42 to pass through needs to be opened on the side of the sliding sleeve 51, and the long hole is located above the fixing hole 53, which will not affect the normal use of the locking mechanism.

[0027] In order to facilitate the soil in the perforated sleeve 3 to be shaken out, reduce the time wasted due to shaking the soil, and improve the efficiency of drilling the seedling holes using the punch, as Figure 1 , Figure 2 As shown, a vibration sleeve 8 is provided on the vertical rod 2, and the vibration sleeve 8 includes an outer sleeve 81 and an inner rod 82. The outer sleeve 81 is welded on the vertical rod 2 and is hollow inside. The inner rod 82 is movably arranged in the outer sleeve 81, and the length of the inner rod 82 is smaller than the length of the outer sleeve 81, and the diameter of the inner rod 82 is smaller than the diameter of the outer sleeve 81. The bottom surface of the outer sleeve 81 is higher than the top surface of the cross bar 4. By arranging the vibration sleeve 8 on the vertical rod 2 and shaking the puncher up and down, the inner rod 82 located in the outer sleeve 81 is driven to shake up and down and left and right, thereby knocking the outer sleeve 81 to generate vibration, which is then transmitted to the cross bar 4 and the punching sleeve 3 connected to the cross bar 4 by the vertical rod 2, and the bottom surface of the outer sleeve 81 is arranged at a position higher than the top surface of the cross bar 4, so as to facilitate the sliding of the sliding mechanism 5 on the cross bar 4. Furthermore, in order to facilitate the storage of the positioner 7 and realize the purpose of taking it for use at any time, the side of the outer sleeve 81 is fixedly provided with a second nut 83 adapted to the threaded section 711. When the positioner 7 is not needed, the positioner 7 can be taken out from the positioning nut 74 on the side of the perforating sleeve 3 and connected to the second nut 83; when the positioner 7 is needed, the positioner 7 is taken out from the second nut and connected to the positioning nut 74 on the side of the perforating sleeve 3.

[0028] In order to facilitate the perforation sleeve 3 to be pressed into the soil, the seedling hole is drilled and arranged. Figure 1 , Figure 2 As shown, the side where the perforating sleeve 3 is connected to the sliding mechanism 5 is vertically arranged, and the bottom of the perforating sleeve 3 is a wedge-shaped surface 31, and the cross-sectional diameter of the perforating sleeve 3 decreases from top to bottom; by setting the wedge-shaped surface 31, the angle between the bottom of the perforating sleeve 3 and the horizontal plane is increased to reduce the shear force of the lower end of the perforating sleeve 3 inserted into the soil, so as to facilitate pressing the perforating sleeve 3 into the soil.
