Description

Technical Field

[0001] The present invention relates to the technical field of greening planting, and specifically to a pit-digging device for greening planting trees and its use method. Background Art

[0002] Landscaping projects are projects for constructing landscape green spaces. Landscaping provides a good place for people to rest, engage in cultural and recreational activities, get close to nature, and satisfy people's desire to return to nature. It is an important measure to protect the ecological environment and improve the urban living environment. Currently, a large number of trees need to be planted in landscaping projects, and the planting of trees requires the excavation of holes in advance. However, the existing pit-digging devices are inconvenient to use and have low efficiency. There are already patent documents that have made improvements in this regard.

[0003] For example, in Chinese Patent CN222396109U, a pit-digging device for tree planting in landscaping project construction includes a square frame fixed outside the pit-digging device body. The pit-digging device body is detachably connected to a support block through a limiting component. The support block is movably connected to the side surface of a side plate. A lifting component for controlling the movement of the support block is installed on the surface of the side plate. Two groups of limiting plates are arranged outside the support block on the side surface of the side plate. Screws are threadedly installed outside the limiting plates and connected to rubber blocks. The pit-digging device body is placed inside the two groups of limiting plates, and the screws are rotated to drive the rubber blocks to move, thereby fixing the pit-digging device body inside the limiting plates, facilitating the installation and disassembly of the pit-digging device body and being convenient for long-term pit-digging use.

[0004] Although the device in the above document can be conveniently disassembled and prevent soil from splashing during pit-digging, it still has obvious defects in actual use, such as: When planting trees currently, in order to ensure that the trees have a suitable growth space and the aesthetics after planting, the spacing between trees is the same. This leads to the need to dig holes at appropriate distances in advance during previous pit-digging. However, the device in the document can only perform single pit-digging work and cannot ensure the distance between pits. Workers need to measure while digging. Although it is also possible to measure and mark points in advance, for a long planting distance, they need to walk back and forth to measure, resulting in a large amount of labor and low efficiency; Therefore, a pit-digging device for greening planting trees that can improve the pit-digging efficiency and accuracy is now designed to solve such defects.

[0014] The present invention also discloses a using method of a pit-digging device for greening and planting trees, which specifically includes the following steps: S1. Before use, first adjust the pit-digging spacing according to the spacing of tree planting. Pull the lifting pressure plate by hand to drive the two positioning tooth blocks to separate from the rectangular notch under the limitation of the vertical rod. At this time, the Y-shaped tooth pressing frame is unlocked. Then push the Y-shaped tooth pressing frame backward until the distance between the camera and the upper top plate frame meets the pit-digging spacing, and then stop. Then release the lifting pressure plate, and under the elastic force of the first spring, push the positioning tooth block to insert into the rectangular notch and mesh with the Y-shaped tooth pressing frame. At this time, the Y-shaped tooth pressing frame is fixed. At the same time, since the two ends of the front part of the Y-shaped tooth pressing frame do not press against the inclined plane guide plate, then flip the L-shaped protective cover to expose the display device. Then pour the pigment water into the liquid storage tank. After pouring the pigment water, manually press the pressing pump several times continuously until the pigment water can flow into the spray pipe through the liquid guide pipe and can be sprayed out by the spray pipe when pressing the pressing pump once later. After the preparation is completed, move the load-bearing bottom plate to the designated pit-digging position by using the tires; S2. Align the annular lifting opening with the digging position. Then start the motor to drive the auger blade to rotate by means of the rotating rod. Next, start the cylinder to push the motor and the annular top plate to descend synchronously under the limit of the guiding and sliding equipment frame. When the annular top plate descends, it will first drive the L-shaped extrusion frame to contact and press the arc-shaped bearing plate. After the arc-shaped bearing plate is pressed, it will drive the nozzle to move backward away from the descending range of the auger blade under the limit of the curved guide plate and the spring-back rod, avoiding hard contact between the nozzle and the auger blade. When the arc-shaped bearing plate moves backward to the rearmost part, the arc-shaped tooth plate meshes with the gear disk to limit the tire. As the annular top plate continues to descend, it will push the splash-proof ring frame to pass through the annular lifting opening and contact the ground by compressing the third spring. Then the tip of the conical plug inserts into the ground to reposition the splash-proof ring frame and the whole equipment. Then, as the annular top plate descends, the auger blade digs a hole inside the auger blade, and the soil during digging will not scatter everywhere and will all accumulate inside the splash-proof ring frame, facilitating subsequent landfill of the trees. S3. After the hole digging is completed, start the cylinder to drive the annular top plate to rise. At this time, the annular top plate will first drive the auger blade and the L-shaped extrusion frame to rise synchronously. When the auger blade is above the annular lifting opening, the L-shaped extrusion frame starts to separate from the arc-shaped bearing plate. At this time, the arc-shaped bearing plate moves forward under the elastic force of the second spring. The forward-moving arc-shaped bearing plate drives the arc-shaped tooth plate to separate from the gear disk. At the same time, the nozzle returns to the center position of the annular lifting opening. As the annular top plate continues to rise, use the pressure vertical rod to pull the splash-proof ring frame to rise and return to the inside of the annular lifting opening. After the annular top plate completely rises to the top, the L-shaped extrusion frame will press the pressing pump. After the pressing pump is pressed, the nozzle sprays some pigment water into the middle of the hole. At this time, the excavation of the first hole is completed. Then pull the front part of the load-bearing bottom plate. At this time, the camera takes pictures of the ground, and the images during shooting are viewed through the display device. During the movement of the load-bearing bottom plate, pigment water is displayed at the display device. At this time, the camera is facing the previous hole. At this time, stop the load-bearing bottom plate to excavate the second hole, and continuously excavate to ensure that the intervals of each hole are the same.

[0015] Preferably, when the Y-shaped tooth pressure frame moves backward in the S1 step, the L-shaped protective cover can be opened. After the Y-shaped tooth pressure frame moves forward and resets, it can use the front extrusion inclined plane guide plate to push the L-shaped protective cover to flip and cover the display device for protection. Beneficial effects

[0016] The present invention provides a hole-digging device for greening and planting trees and its use method. Compared with the existing technology, it has the following beneficial effects: (1) The tree pit-digging equipment for greening planting and its using method, by using the marking and distance-measuring mechanism and the pit-digging and splash-proof mechanism in a combined manner. The settings of these two mechanisms can utilize the power when the air cylinder pushes the annular top plate to rise, and with the linkage between the structures, it can successively achieve the fixation of the equipment, splash-proof, pit-digging, and most importantly, marking. Then, by observing through the display device, the equipment can be quickly moved to a suitable spacing while digging the pit, thus effectively improving the efficiency of pit-digging and being convenient to use.

[0017] (2) The tree pit-digging equipment for greening planting and its using method, by installing a Y-shaped tooth pressing frame on the top of the upper top plate frame, and installing a camera at the rear of the Y-shaped tooth pressing frame, and using it in combination with the display device and the inclined guide plate. The settings of these structures can, when the auger blade finishes digging the pit and rises, use the L-shaped extrusion frame to press the pressing pump, so that the spray pipe sprays a small amount of pigment water into the pit. Then, during the movement of the load-bearing bottom plate, the position of the pigment water can be observed in real time through the display device and the camera. When the display device can see the pigment water, the camera is facing the previous pit. At this time, digging the pit again can ensure that the spacing between the pits is more accurate, and there is no need for the staff to perform pre-measurement or real-time measurement, improving the work efficiency and reducing the labor intensity.

[0018] (3) The tree pit-digging equipment for greening planting and its using method, by setting an annular top plate at the bottom of the annular top plate, and connecting an anti-splash ring frame through the annular top plate, and using it in combination with the L-shaped extrusion frame. The settings of these structures can, when the annular top plate descends, first let the L-shaped extrusion frame squeeze the arc-shaped bearing plate to drive the spray pipe out of the descending range of the auger blade, ensuring that there is no conflict during the descent. Then, before digging the pit, let the anti-splash ring frame cover the ground, which can not only prevent splashing, but also accumulate the soil around the pit, facilitating the quick backfilling of the soil after planting the tree, effectively improving the overall practicality and functionality of the equipment.

[0025] The present invention also discloses a using method of a pit-digging device for greening and planting trees, which specifically includes the following steps: S1. Before use, first adjust the pit-digging spacing according to the spacing of tree planting. Pull the lifting pressing plate 110 by hand to drive the two positioning tooth blocks 112 to separate from the rectangular notch 108 under the limitation of the vertical rod 109. At this time, the Y-shaped tooth pressing frame 107 is unlocked. Then push the Y-shaped tooth pressing frame 107 backward until the distance between the camera 113 and the upper top plate frame 102 meets the pit-digging spacing and then stop. Then release the lifting pressing plate 110, and under the elastic force of the first spring 111, push the positioning tooth block 112 to insert into the rectangular notch 108 and engage with the Y-shaped tooth pressing frame 107. At this time, the Y-shaped tooth pressing frame 107 is fixed. At the same time, since the two ends of the front part of the Y-shaped tooth pressing frame 107 do not press against the inclined guide plate 105, then flip the L-shaped protective cover 104 to expose the display device 103. Then pour the pigment water into the liquid storage tank 125. After pouring the pigment water, manually press the pressing pump 126 several times continuously until the pigment water can flow into the spray pipe 124 through the liquid guide pipe 127 and the spray pipe 124 can spray out when pressing the pressing pump 126 once later. After the preparation is completed, move the load-bearing bottom plate 101 to the designated pit-digging position by using the tires 117; S2. Align the annular lifting opening 114 with the digging position. Then start the motor 203 to drive the auger blade 211 to rotate by means of the rotating rod 210. Then start the cylinder 202 to push the motor 203 and the annular top plate 206 to descend synchronously under the limitation of the guiding and sliding equipment frame 201. When the annular top plate 206 descends, it will first drive the L-shaped extrusion frame 209 to contact and press the arc-shaped bearing plate 120. After the arc-shaped bearing plate 120 is pressed, it will drive the nozzle 124 to move backward away from the descending range of the auger blade 211 under the limitation of the bent guide plate 119 and the return spring rod 121, avoiding hard contact between the nozzle 124 and the auger blade 211. When the arc-shaped bearing plate 120 moves backward to the rearmost part, the arc-shaped tooth plate 123 meshes with the gear disk 118 to limit the tire 117. As the annular top plate 206 continues to descend, it will push the splash-proof ring frame 204 to pass through the annular lifting opening 114 and contact the ground by compressing the third spring 208. Then the tip of the conical insert 205 inserts into the ground to reposition the splash-proof ring frame 204 and the whole equipment. Then as the annular top plate 206 descends, the auger blade 211 digs a hole inside the auger blade 211, and the soil during digging will not scatter everywhere and will all accumulate inside the splash-proof ring frame 204, facilitating subsequent landfill of trees. S3. After the hole digging is completed, start the cylinder 202 to drive the annular top plate 206 to rise. At this time, the annular top plate 206 will first drive the auger blade 211 and the L-shaped extrusion frame 209 to rise synchronously. When the auger blade 211 is located above the annular lifting opening 114, the L-shaped extrusion frame 209 starts to separate from the arc-shaped bearing plate 120. At this time, the arc-shaped bearing plate 120 moves forward under the elastic force of the second spring 122. The forward-moving arc-shaped bearing plate 120 drives the arc-shaped tooth plate 123 to separate from the gear disk 118. At the same time, the nozzle 124 returns to the center position of the annular lifting opening 114 again. As the annular top plate 206 continues to rise, use the pressure vertical rod 207 to pull the splash-proof ring frame 204 to rise and return to the inside of the annular lifting opening 114. After the annular top plate 206 completely rises to the top, the L-shaped extrusion frame 209 will press the pressing pump 126. After the pressing pump 126 is pressed, the nozzle 124 sprays part of the pigment water to the middle of the hole. At this time, the excavation of the first hole is completed. Then pull the front part of the load-bearing bottom plate 101. At this time, the camera 113 takes pictures of the ground, and the image during shooting is viewed through the display device 103. During the movement of the load-bearing bottom plate 101, the pigment water is displayed at the display device 103. At this time, the camera 113 is facing the previous hole. At this time, stop the load-bearing bottom plate 101 to excavate the second hole. Continuously excavate to ensure that the spacing of each hole is the same. The backward movement of the Y-shaped tooth pressing frame 107 in step S1 can open the L-shaped protective cover 104, and after the Y-shaped tooth pressing frame 107 moves forward and resets, it can use the front-end extrusion inclined plane guide plate 105 to push the L-shaped protective cover 104 to flip and cover the display device 103 for protection.

Before use, the spacing of the pits is adjusted according to the spacing of the trees planted. The lifting and lowering pressure plate (110) is pulled by hand to drive the two positioning tooth blocks (112) to separate from the rectangular notch (108) under the limit of the vertical rod (109). At this time, the Y-shaped tooth pressure frame (107) is unlocked, and then the Y-shaped tooth pressure frame (107) is pushed backward until the distance between the camera (113) and the upper top plate frame (102) meets the spacing of the pits. Then, the lifting and lowering pressure plate (110) is released, and the positioning tooth block (112) is pushed into the rectangular notch (108) under the elastic force of the first spring (111) and meshed with the Y-shaped tooth pressure frame (107). At this time, the Y-shaped tooth pressure frame (107) is fixed, and since the two ends of the front of the Y-shaped tooth pressure frame (107) are not pressed against the inclined guide plate (105), the L-shaped protective cover (104) is then flipped to expose the display device (103), and then the pigment water is put into the liquid storage tank (125). After the pigment water is put into the liquid storage tank (125), the pressing pump (126) is manually pressed several times continuously until the pigment water can flow into the nozzle (124) through the liquid guide tube (127), and the nozzle (124) can be sprayed out when the pressing pump (126) is pressed once later. After the preparation is completed, the load-bearing bottom plate (101) is moved to the designated digging position using the tire (117); S2, align the annular lifting opening (114) with the digging position, then start the motor (203) and use the rotating rod (210) to drive the auger blade (211) to rotate, and then start the cylinder (202) to push the motor (203) and the annular top plate (206) to descend synchronously under the limit of the guide slide device frame (201), and when the annular top plate (206) descends, it first drives the L-shaped extrusion frame (209) to contact and press the arc-shaped pressure plate (120), and after the arc-shaped pressure plate (120) is pressed, it drives the nozzle (124) to move backward and leave the descending range of the auger blade (211) under the limit of the curved guide plate (119) and the rebound rod (121), so as to prevent the nozzle (124) and the auger blade (211) from being in contact with each other. ) is rigidly opposed, and when the arc-shaped pressure plate (120) moves to the rearmost part, the arc-shaped tooth plate (123) engages with the gear plate (118) to limit the tire (117), and as the annular top plate (206) continues to descend, the third spring (208) is compressed to push the splash-proof ring frame (204) through the annular lifting opening (114) to contact the ground, and then the tip of the conical plug block (205) is inserted into the ground to reposition the splash-proof ring frame (204) and the entire device, and then as the annular top plate (206) descends, the auger blade (211) digs a pit on the inner side of the auger blade (211), and the soil during the digging will not be scattered and will be all accumulated on the inner side of the splash-proof ring frame (204), so that it is convenient for the subsequent landfill of the trees; S3. After the pit is dug, the cylinder (202) is started to drive the annular top plate (206) to rise. At this time, the annular top plate (206) will first drive the auger blade (211) and the L-shaped extrusion frame (209) to rise synchronously. When the auger blade (211) is located at the upper part of the annular lifting opening (114), the L-shaped extrusion frame (209) begins to separate from the arc-shaped pressure plate (120). At this time, the arc-shaped pressure plate (120) moves forward under the elastic force of the second spring (122). The forward-moving arc-shaped pressure plate (120) drives the arc-shaped gear plate (123) to separate from the gear plate (118). At the same time, the nozzle (124) is relocated to the center of the annular lifting opening (114). When the annular top plate (206) continues to rise, the pressure vertical rod (207) is used to pull the splash-proof ring frame (204) ) rises and returns to the inner side of the annular lifting port (114). After the annular top plate (206) rises completely to the top, the L-shaped extrusion frame (209) presses the pressing pump (126). After the pressing pump (126) is pressed, the nozzle (124) sprays part of the pigment water out of the middle of the pit. At this time, the excavation of the first pit is completed. Then, the front of the load-bearing bottom plate (101) is pulled. At this time, the camera (113) shoots the ground, and the image is viewed through the display device (103). During the movement of the load-bearing bottom plate (101), the pigment water is displayed at the display device (103). At this time, the camera (113) is facing the previous pit. At this time, the load-bearing bottom plate (101) is stopped to excavate the second pit. Continuous excavation ensures that the indirection of each pit is the same.
