Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a positionable hole puncher. Background Art

[0002] When planting vegetable seedlings or sowing seeds, a soil puncher such as that described in CN205847914U is often used for drilling holes. However, when drilling holes for planting seedlings, it is necessary to locate the holes in advance, that is, to draw a line to determine the spacing, or to make points on the ground film in advance to ensure that the holes for planting seedlings are located in the same straight line and have equal spacing. This requires a lot of manpower for preparation work, and only one hole for planting seedlings can be drilled at a time, resulting in low drilling efficiency. For example, in the application number CN2024214814517, a soil puncher such as that described in CN205847914U requires a hole for planting seedlings, and a hole for planting seedlings is drilled at a time, resulting in low drilling efficiency. The soil-shaking hole puncher comprises a vertical rod and a grip rod arranged in a T shape, a punching sleeve is provided at one end of the vertical rod away from the grip rod, a pedal is provided at the side of the vertical rod away from the punching sleeve, a cross rod connected to the punching sleeve is provided at one end of the vertical rod away from the grip rod, and a vibration sleeve is provided at one end of the cross rod; although the vibration sleeve can be used in conjunction with the punching sleeve to achieve drilling of equally spaced seedling holes, since it needs to place the vibration sleeve and the adjacent punching sleeve in the previously drilled seedling hole, the drilling of one seedling hole will be wasted, and the drilling efficiency is low.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The present utility model will be further described below.

[0022] The utility model provides a positionable puncher, which is mainly used for drilling holes for seedlings, and comprises a grip rod 1, a vertical rod 2, a punching sleeve 5, a cross bar 3 and a pedal 4; the grip rod 1 is vertically arranged at one end of the vertical rod 2, the cross bar 3 is vertically arranged at the other end of the vertical rod 2, an I-shape is formed between the grip rod 1, the vertical rod 2 and the cross bar 3, the punching sleeve 5 is fixedly arranged on one side of the cross bar 3, and the pedal 4 is arranged on the side of the cross bar 3 away from the punching sleeve 5; the utility model is characterized in that: it also comprises a positioner 6 arranged at one end of the cross bar 3, and the positioner 6 comprises an extension rod 61, The first positioning vertical rod 62 and the second positioning vertical rod 63, the extension rod 61 is arranged at one end of the cross bar 3 along the length direction of the cross bar 3, the first positioning vertical rod 62 and the second positioning vertical rod 63 are arranged on the extension rod 61 at intervals along the length direction of the extension rod 61, the first positioning vertical rod 62 and the second positioning vertical rod 63 are both vertically arranged on the extension rod 61 and parallel to the perforating sleeve 5, the spacing between the first positioning vertical rod 62 and the adjacent perforating sleeve 5 is equal to the spacing between the first positioning vertical rod 62 and the second positioning vertical rod 63.

[0023] like Figure 1 As shown, the positionable hole puncher includes a grip rod 1, a vertical rod 2 and a horizontal rod 3 arranged in an "I" shape, and a hole punching sleeve 5 is fixedly connected to one side of the horizontal rod 3. The hole punching sleeve 5 can adopt a hole punching tube structure as recorded in CN205847914U "Soil Hole Puncher", or an existing cylindrical hole punching tube structure; a pedal 4 is arranged on the side of the horizontal rod 3 away from the hole punching sleeve 5, so that when the pedal 4 is stepped on, it will not hinder the insertion of the hole punching sleeve 5 into the soil, and the pedal 4 can further limit the depth of the seedling planting hole drilled by the hole punching sleeve 5, that is, when the pedal 4 is in contact with the ground, it will generate a large resistance. At this time, stopping stepping on it can control the depth of the seedling planting hole drilled; similarly, the horizontal rod 3 can also limit the depth of the seedling planting hole drilled by the hole punching sleeve 5. A locator 6 is provided at one end of the cross bar 3. The locator 6 can be provided at the left end or the right end of the cross bar 3, so that the locator 6 is always located at the rear side of the seedling planting hole to be drilled, that is, the locator 6 is always located behind the foot used by the operator when stepping on the pedal 4. Figure 1The locator 6 is arranged on the left side of the cross bar 3 so that when the operator presses the pedal 4 with his right foot, the locator 6 is located behind the operator, that is, it can be aligned with the seedling planting hole that has been drilled; but it should be noted that the locator must be on the same side of the cross bar 3 as the perforating sleeve 5. Specifically, the locator 6 includes an extension rod 61, a first positioning vertical rod 62 and a second positioning vertical rod 63. The extension rod 61 is arranged at one end of the cross bar 3 along the length direction of the cross bar 3 so that the extension rod 61 and the cross bar 3 are located in the same straight line. The first positioning vertical rod 62 and the second positioning vertical rod 63 are arranged on the extension rod 61 in sequence, and the first positioning vertical rod 62 and the second positioning vertical rod 63 are both vertically arranged on the extension rod 61 and facing the ground. The first positioning vertical rod 62 and the second positioning vertical rod 63 are parallel to the perforating sleeve 5. By adjusting the distance between the first positioning vertical rod 62 and the adjacent perforating sleeve 5, the distance is adjusted to the perforating sleeve 5 to be drilled. The spacing of the seedling planting holes is consistent, and the spacing between the first positioning vertical rod 62 and the adjacent punching sleeve 5 is equal to the spacing between the first positioning vertical rod 62 and the second positioning vertical rod 63, so that the punching sleeve 5, the first positioning vertical rod 62, and the second positioning vertical rod 63 are arranged at equal intervals, and the spacing is the same as the spacing of the seedling planting holes to be drilled. When drilling the seedling planting holes, first drill two seedling planting holes, and then align the first positioning vertical rod 62 and the second positioning vertical rod 63 with the two seedling planting holes drilled first one by one. According to the principle of "two points determine a straight line", at this time, the first positioning vertical rod 62 and the second positioning vertical rod 63 are always located The punching sleeve 5 on the same straight line is also on the same straight line as the previously drilled seedling holes, and since the spacing between the first positioning vertical rod 62 and the seedling holes is equal to the spacing between the first positioning vertical rod 62 and the second positioning vertical rod 63, that is, the position of the punching sleeve 5 is equal to the spacing of the previously drilled seedling holes corresponding to the first positioning vertical rod 62 and the second positioning vertical rod 63, such an arrangement can realize the equal spacing of the seedling holes without the need for advance dotting and positioning, and the seedling holes are always on the same straight line, and there is no need for the operator to repeatedly measure the distance, pull the wire and dot to ensure the spacing between the seedling holes and whether the seedling holes are on the same straight line, thereby saving punching time, The drilling efficiency is improved while the labor intensity of the operators is reduced. The positionable hole puncher is used to drill holes for planting seedlings. The operators do not need to bend over during the whole process to complete the drilling of the holes for planting seedlings. For example, the punching sleeve 5 can be pressed down by stepping on it so that it can be inserted into the soil for drilling holes; the punching sleeve 5 can be lifted up and separated from the soil by pulling the gripping rod 1 to shake the soil; the subsequent seedling holes can be positioned and drilled by aligning the first positioning vertical rod 62 and the second positioning vertical rod 63 of the positioner 6 with the previously drilled seedling holes before inserting the punching sleeve 5, thereby ensuring that the drilled seedling holes are always drilled at equal intervals and located in the same straight line.

[0024] To prevent the first positioning vertical rod 62 and the second positioning vertical rod 63 from being too long and affecting the drilling depth of the seedling planting hole when inserted into the already drilled seedling planting hole, the bottom ends of the first positioning vertical rod 62 and the second positioning vertical rod 63 are higher than the bottom end of the drilling sleeve 5; with this setting, when the positioner 6 moves downward with the positionable drilling tool, the first positioning vertical rod 62 and the second positioning vertical rod 63 will not touch the bottom of the already drilled seedling planting hole, and will not affect its hole depth.

[0025] To facilitate the replacement and disassembly of the positioner 6 to achieve replacing the positioner 6 with an appropriate spacing according to the actual drilling requirements, such as Figure 1 、 Figure 2 As shown, the positioner 6 is detachably arranged on the cross bar 3. A positioning nut 31 is fixedly arranged on the cross bar 3. One end of the extension rod 61 away from the second positioning vertical rod 63 is provided with a threaded rod 64, and the threaded rod 64 is in threaded connection with the positioning nut 31; specifically, by using the threaded connection between the threaded rod 64 arranged at one end of the extension rod 61 and the positioning nut 31, the detachable connection between the entire positioner 6 and the cross bar 3 is realized. With this setting, only a threaded rod 64 needs to be welded at one end of the extension rod 61, and a positioning nut 31 threadedly connected to the threaded rod 64 is arranged on the cross bar 3. Its design is simple and the cost is low.

[0026] To ensure the connection stability between the threaded rod 64 and the positioning nut 31, as Figure 1 shown, a back-tightening nut 65 is in threaded connection with the threaded rod 64, and the back-tightening nut 65 is located between the positioning nut 31 and the first positioning vertical rod 62; by screwing the back-tightening nut 65 until it abuts against the positioning nut 31, the connection stability between the extension rod 61 and the positioning nut 31 is ensured.

[0027] To facilitate the ready access and storage of the positioner 6, as Figure 1 or Figure 2 shown, a fixing ring 21 for storing the positioner 6 is arranged on the vertical rod 2. An opening for the threaded rod 64 to pass through is provided at the center of the fixing ring 21. A fixing nut 22 in threaded connection with the threaded rod 64 is rotatably arranged on one side of the fixing ring 21; as Figure 2 shown, when the positioner 6 is not in use, the threaded rod 64 of the extension rod 61 can be passed through the fixing ring 21 and threadedly connected with the fixing nut 22 rotatably arranged on the fixing ring 21, so as to fix the entire positioner 6 on the vertical rod 2. When it is not needed, it will not affect the normal use of the positionable drilling tool, and when the positioner 6 needs to be used, it can also be seen at a glance without the need for additional storage.

[0028] To reduce the weight of the entire positionable drilling tool and lower the labor intensity of the operator, as Figure 3As shown, the first positioning vertical rod 62 is a lead screw, and the second positioning vertical rod 63 is a chain. Using a chain for the second positioning vertical rod 63 can not only reduce the weight, but also, since it is a movable strip, and since the positioner 6 is detachably installed by screwing, it is possible to determine whether the first positioning vertical rod 62 and the second positioning vertical rod 63 are parallel to the punching sleeve 5 by observing whether the chain is in a natural hanging state, thereby ensuring that the drilled seedling planting holes are always on the same straight line. At the same time, the pedal 4 can be replaced with a treadle rod 41, and at least two spaced-apart treadle rods 41 can meet the needs of the operator to step on. Such a setting can also reduce the weight of the entire positionable punch and reduce the labor intensity.

[0029] To achieve the ability to drill multiple seedling planting holes at one time, as Figure 3 shown, a plurality of punching sleeves 5 arranged along the length direction of the cross bar 3 are evenly spaced on the cross bar 3. The spacing between the punching sleeves 5 can be set according to the actual spacing of the seedling planting holes, so that the drilled seedling planting holes meet the seedling planting requirements.

[0030] After the positionable punch with multiple punching sleeves 5 drills multiple seedling planting holes, to ensure that the soil in the punching sleeves 5 can be quickly shaken out for drilling the next set of seedling planting holes, as Figure 3As shown in the figure, the positionable punch further includes a vibration sleeve 7 provided on the vertical rod 2. The vibration sleeve 7 includes an outer sleeve 71 and an inner rod 72. The inner part of the outer sleeve 71 is hollow. The inner rod 72 is movably arranged inside the outer sleeve 71. The length of the inner rod 72 is less than that of the outer sleeve 71, and the diameter of the inner rod 72 is less than that of the outer sleeve 71. The bottom surface of the outer sleeve 71 is welded to the top surface of the cross bar 3. The vibration sleeve 7 is arranged on the vertical rod 2 at the middle position of the cross bar 3, so that the vibration force of the vibration sleeve 7 can be evenly transmitted to the punching sleeves 5 on both sides of the vertical rod 2 to ensure that the soil in each punching sleeve 5 can be shaken out; the bottom surface of the vibration sleeve 7 is welded to the top surface of the cross bar 3, so that when the punching sleeve 5 is pressed down, the vibration sleeve 7 will not affect the normal drilling of the seedling planting holes. And the side surface of the vibration sleeve 7 is welded to the vertical rod 2, and the bottom surface of the vibration sleeve 7 is welded to the top surface of the cross bar 3, which is beneficial to strengthening the whole punch; the vibration sleeve 7 includes an outer sleeve 71 and an inner rod 72. The outer sleeve 71 is a fully enclosed sleeve with a hollow inner part, and the length of the inner rod 72 is less than that of the outer sleeve 71, so that the inner rod 72 can slide up and down inside the outer sleeve 71. The diameter of the inner rod 72 is less than that of the outer sleeve 71, so that the inner rod 72 can swing left and right inside the outer sleeve 71, that is, the inner rod 72 can slide up and down and swing left and right inside the closed outer sleeve 71, so that the inner rod 72 impacts the outer sleeve 71 to make the outer sleeve 71 vibrate, and then the vibration is transmitted to the punching sleeve 5 through the cross bar 3, so that the soil in the punching sleeve 5 is vibrated and separated from the inner wall of the punching sleeve 5, and finally separated from the punching sleeve 5. When the punch is pulled out, shaking the punch up and down can realize the removal of the soil body in the punching sleeve 5, without bending down to knock on the punching sleeve 5, reducing the labor intensity of the operator and saving the time of repeatedly knocking to remove the soil, that is, the sticky soil can be quickly shaken out after drilling, and the seedling planting holes can be drilled quickly and continuously, improving the drilling efficiency and ensuring the drilling quality.

[0031] As a preferred method, to strengthen the vibration force of the vibration sleeve 7, the above-mentioned vibration sleeve 7 can also adopt the structure as Figure 4 shown. Specifically, two oppositely arranged through holes 73 are opened on the side surface of the outer sleeve 71. A limiting rod 74 that penetrates through the two through holes 73 and has a length greater than the diameter of the outer sleeve 71 is arranged in the two through holes 73. The limiting rod 74 is parallel to the cross bar 3. The upper end of the inner rod 72 is welded to the limiting rod 74 to form a T shape. The length and width of the through hole 73 are both greater than the diameter of the limiting rod 74. Welding a limiting rod 74 that penetrates through the outer sleeve 71 at the top end of the inner rod 72. To ensure that the inner rod 72 can still slide up and down and swing left and right inside the outer sleeve 71, two oppositely arranged through holes 73 are opened on the upper side surface of the outer sleeve 71, and as Figure 5As shown, the length and width of the through hole 73 are both greater than the diameter of the limit rod 74, enabling the limit rod 74 to move up and down and sway left and right within the through hole 73. That is, it ensures that the built-in rod 72 can move up and down and sway left and right within the outer sleeve 71, hitting the outer sleeve 71 to generate vibration. And due to the addition of the limit rod 74 that penetrates the outer sleeve 71, the limit rod 74 can also hit the outer sleeve 71 to generate vibration. That is, it increases the vibration intensity when the vibrating sleeve 7 moves up and down with the operator, realizing the vibration of the soil within the drilling sleeve 5 to accelerate the soil shaking speed.

[0032] It should be noted that after the vibrating sleeve 7 is set, the above-mentioned fixing ring 21 for placing the unused locator 6 can be set on the vibrating sleeve 7 or on the vertical rod 2.

[0033] To facilitate pressing the drilling sleeve 5 into the soil body for drilling the seedling planting hole, one side of the drilling sleeve 5 connected to the cross bar 3 is vertical, the bottom of the drilling sleeve 5 is a wedge-shaped surface, and the cross-sectional diameter of the drilling sleeve 5 decreases from top to bottom. Such a setting makes the angle between the wedge-shaped surface at the bottom of the drilling sleeve 5 and the horizontal plane increase, so as to reduce the shear force when the lower end of the drilling sleeve 5 is inserted into the soil body and facilitate pressing the drilling sleeve 5 into the soil body.
