Description

Technical Field

[0001] The invention relates to the field of tea tree planting, in particular to a hole digging machine used for tea tree planting. Background Art

[0002] There are many different ways to grow tea trees, but they can generally be divided into two categories: traditional planting and modern planting.

[0003] In traditional planting methods, farmers usually rely on manpower and simple tools to plant tea trees. In the selected planting area, farmers first level the land and remove weeds, and then use hoes or similar tools to dig holes in the ground according to the predetermined row and plant spacing. The depth and width of the hole are determined according to the variety of tea trees and soil conditions to ensure that the tea trees can grow stably and absorb enough nutrients after planting. Then, farmers put the seedlings or seeds of the tea trees into the dug holes and carry out subsequent operations such as covering with soil and watering. Although this planting method is time-consuming and labor-intensive, it can better adapt to various complex land conditions.

[0004] Modern planting methods make more use of mechanization and automation technology. By introducing advanced agricultural machinery and equipment, such as digging machines and planting machines, the efficiency of tea tree planting can be greatly improved. These mechanical equipment can quickly and accurately dig holes and plant according to preset parameters, greatly reducing the labor intensity of farmers. At the same time, modern planting methods also focus on scientific guidance in land improvement, water and fertilizer management, etc., to improve the survival rate and yield of tea trees.

[0005] However, when planting tea trees on terraced terrain, due to the stepped structure of the terraces and the narrow working space, conventional hole digging machines are not easy to carry and operate on the terraces. This requires farmers to spend more time and energy to dig holes manually during the hole digging process of tea tree planting. They have to climb step by step along the steps of the terraces and use simple tools to dig holes, which not only increases labor intensity but also reduces planting efficiency.

[0006] Therefore, it is very necessary to design a hole-digging machine for tea tree planting that can be easily transported on terraced fields. Summary of the invention

[0007] In order to overcome the disadvantage that when tea trees are planted on stepped terraces, conventional hole digging machines are not convenient to carry and operate on terraces, resulting in reduced tea tree planting efficiency, the present invention provides a hole digging machine for tea tree planting that is easy to move on terraces.

[0008] The technical solution of the present invention is: a hole digging machine for tea tree planting, including a mobile bracket, traveling wheels, a support platform and an auger, the bottom of the mobile bracket is provided with a traveling wheel, the support platform is slidably connected in the mobile bracket, the auger is connected to the support platform, and also includes a lifting bracket, a second motor and a transmission assembly, the lifting bracket is slidably connected to one end of the mobile bracket, the second motor is fixed on the mobile bracket, and the second motor drives the lifting bracket to slide through the transmission assembly.

[0009] In addition, a more excellent solution is to further include a first screw rod, which is rotatably connected in the movable bracket, the first screw rod is threadedly connected to the support platform, the first motor supplies energy to the first screw rod, and the guide rod is fixed in the movable bracket to slide and limit the support platform.

[0010] In addition, a more excellent solution is to also include a second screw rod, the lifting bracket is provided with the second screw rod, the transmission assembly is two bevel gears meshing with each other, one of the bevel gears is connected to the second motor output shaft through a key, and the other bevel gear is rotatably connected to the lifting bracket, the inner ring of the bevel gear is provided with an internal thread, and the bevel gear is nested in the second screw rod through the internal thread.

[0011] In addition, a more excellent solution is to further include a cleaning wheel disc, which is rotatably connected to the movable bracket and is located outside the auger.

[0012] In addition, a more excellent solution is that the cleaning wheel is provided with cleaning brushes arranged centripetally.

[0013] In addition, a more excellent solution is to also include a one-way rotating component for cleaning the surface of the spiral drill, the one-way rotating component is composed of a gear ring, a transmission ring, a one-way paddle and a pulley group, the gear ring is fixed to the outside of the cleaning wheel, the transmission ring is rotatably mounted on the outer ring of the gear ring, a one-way paddle is arranged on the inner side of the transmission ring, and the pulley group is mounted on the output shaft of the first motor and the transmission ring.

[0014] In addition, a better solution is to also include a guide plate, which is radially arranged and rotatably connected to the bottom of the cleaning wheel disc. Specifically, a fixed rod is fixed to the bottom of the cleaning wheel disc, the guide plate is rotatably connected to the end of the fixed rod, and a torsion spring is connected to the connection between the guide plate and the fixed rod.

[0015] In addition, a more excellent solution is that the mobile bracket is equipped with an armrest.

[0016] In addition, a more excellent solution is that the traveling wheel is provided with protruding anti-skid bumps.

[0017] The beneficial effects of the present invention are: 1. Turn on the second motor and drive the second screw to rotate through the transmission assembly, thereby driving the lifting bracket to move upward. After the lifting bracket moves to the upper step of the terrace, the second motor is controlled to rotate in the opposite direction to drive the movable bracket to move upward. The staff only needs to lightly push the movable bracket to move the device to the upper step, thereby realizing displacement within the terrace, which effectively improves the convenience of use and the efficiency of digging pits.

[0018] 2. A cleaning disc, a one-way rotating component and a guide plate are provided. When the auger moves downward to drill a hole, the cleaning disc does not rotate. When the auger completes digging and moves upward, the cleaning disc rotates and scrapes off the soil attached to the surface of the auger. The scraped soil falls into the periphery of the pit through the guide plate, thereby solving the problem of some soil backflow when the auger leaves the pit. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] Embodiment: A hole digging machine for tea tree planting, such as Figure 1-Figure 5 As shown, it includes a mobile bracket 1, a traveling wheel 2, a support platform 3 and an auger 4. A handrail 101 is fixedly connected to the left side of the mobile bracket 1 for the staff to push and stabilize the device. A traveling wheel 2 is arranged at the bottom of the mobile bracket 1. The traveling wheel 2 is provided with a protruding anti-skid bump, so that the traveling wheel 2 still has a high mobility in muddy soil. The first screw rod 5 is rotatably connected to the mobile bracket 1, and the first screw rod 5 is threadedly connected to the support platform 3. The first motor 501 supplies energy to the first screw rod 5. The guide rod 502 is fixedly connected to the mobile bracket 1 to slide and limit the support platform 3. The auger 4 is fixedly connected to the support platform 3 by bolts. The auger 4 has its own power. The first motor 501 drives the support platform 3 to move through the first screw rod 5. The height adjustment also includes a lifting bracket 6, a second motor 7 and a transmission assembly 701. The lifting bracket 6 is slidably connected to the right end of the mobile bracket 1. The second motor 7 is fixed on the mobile bracket 1. The second motor 7 drives the lifting bracket 6 to slide through the transmission assembly 701. The lifting bracket 6 is provided with a second screw rod 601. The second screw rod 601 is connected to the transmission assembly 701 through a thread. The transmission assembly 701 is two bevel gears meshing with each other, one of which is connected to the output shaft of the second motor 7 through a key, and the other bevel gear is rotatably connected to the lifting bracket 6. The inner ring of the bevel gear is provided with an internal thread, and the bevel gear is nested in the second screw rod 601 through the internal thread. In this embodiment, the first motor 501 and the second motor 7 are both servo motors.

[0030] like Figure 6 , Figure 7 and Figure 8 As shown, a cleaning wheel 8 is also included. The cleaning wheel 8 is rotatably connected to the mobile bracket 1 through an extension bracket. The cleaning wheel 8 is located outside the auger 4. The cleaning wheel 8 is provided with a centripetally arranged cleaning brush 801. The cleaning brush 801 is made of hard rubber material, which not only does not affect the up and down passage of the auger 4, but also can fit tightly to the surface of the auger 4, thereby scraping off the soil attached to the surface of the auger 4.

[0031] like Figure 6 and Figure 7As shown, it also includes a one-way rotating component for cleaning the surface of the auger 4, the one-way rotating component is composed of a ring gear 9, a transmission ring 10, a one-way paddle 1001 and a pulley group 11, the ring gear 9 is fixedly connected to the outside of the cleaning wheel 8, the transmission ring 10 is rotatably sleeved on the outer ring of the ring gear 9, and a one-way paddle 1001 is arranged on the inner side of the transmission ring 10, and the one-way paddle 1001 is rotatably connected to the transmission ring 10 through a torsion spring. It is worth noting that the one-way paddle 1001 only rotates counterclockwise and is initially inclined in the counterclockwise direction. Therefore, when the transmission ring 10 rotates clockwise, the transmission ring 10 cannot drive the ring gear 9 to rotate through the one-way paddle 1001, and when the transmission ring 10 rotates counterclockwise, the transmission ring 10 will drive the ring gear 9 to rotate through the one-way paddle 1001, and then drive the cleaning wheel 8 to rotate, and the pulley group 11 is sleeved on the output shaft of the first motor 501 and the transmission ring 10.

[0032] like Figure 1 and Figure 8 As shown, it also includes a guide plate 13, which is radially arranged and rotatably connected to the bottom of the cleaning wheel disc 8. Specifically, a fixing rod 12 is fixed to the bottom of the cleaning wheel disc 8, and the guide plate 13 is rotatably connected to the end of the fixing rod 12. A torsion spring 14 is connected to the connection between the guide plate 13 and the fixing rod 12. The guide plate 13 is initially inclined outward. When the cleaning brush 801 scrapes off the soil attached to the auger 4, the soil will pass through the guide plate 13 and fall outside the pit, preventing the soil from flowing back after the auger 4 leaves the pit.

[0033] The working principle of the embodiment of the present invention is as follows: the staff member holds the handrail 101 and pushes the device to the right. After the device is pushed to the tea tree planting location, the first motor 501 is turned on to drive the first screw rod 5 to rotate clockwise. The first screw rod 5 will drive the base 3 to move downward. After the auger 4 is turned on, the auger 4 will penetrate into the soil to drill holes. During the clockwise rotation of the output shaft of the first motor 501, the transmission ring 10 is driven to rotate clockwise through the pulley group 11. Since the one-way paddle 1001 arranged on the inner side of the transmission ring 10 can only rotate counterclockwise, the transmission ring 10 will not drive the gear ring 9 to rotate when it rotates clockwise, nor will it cause the gear ring 9 to rotate. The cleaning wheel disc 8 is driven to rotate, and the auger 4 can pass through the cleaning wheel disc 8 smoothly. After the auger 4 completes drilling, the first motor 501 is controlled to rotate in the opposite direction. The first motor 501 drives the support 3 to move upward through the first screw rod 5. At the same time, the first motor 501 drives the transmission ring 10 to rotate counterclockwise. At this time, the one-way paddle 1001 will engage with the gear ring 9, and the transmission ring 10 thereby drives the cleaning wheel disc 8 to rotate counterclockwise. The inner ring of the cleaning wheel disc 8 is provided with a cleaning brush 801 made of hard rubber. During the rising period of the auger 4, the cleaning brush 801 can scrape and clean the mud attached to the surface of the auger 4, peeling off the mud. The soil will fall into the guide plate 13 and fall beside the planting hole under the action of the inclined guide plate 13, so as to prevent the soil from falling into the hole again when the auger 4 is taken out, and the digging process of tea tree planting is completed. After the digging work of the whole row of terraces is completed, the device is moved to the side of the terrace. At this time, the device needs to be moved to the upper step of the terrace. The staff can rotate the device 90 degrees toward the upper terrace, and then turn on the second motor 7 and drive the second screw 601 to rotate through the transmission assembly 701, so as to lift the lifting bracket 6 upward. After the lifting bracket 6 is lifted to the height of the upper step, the device is pushed forward to make The lifting bracket 6 is located at the upper step, and then the second motor 7 is controlled to rotate in the opposite direction. At this time, since the height of the lifting bracket 6 has been determined, the mobile bracket 1 will move upward. The staff only needs to hold the handrail 101 to ensure the balance of the device. The traveling wheel 2 of the mobile bracket 1 will fit the side of the upper step, further assisting the mobile bracket 1 to rise smoothly to the height of the upper step. The staff then gently pushes the device forward, and the device can be safely and quickly moved to the upper step. The staff pushes the device back and forth on the stairs to efficiently drill holes, thereby improving the existing inefficient operation of digging holes using traditional tools.
