Abstract
Description
Technical Field
[0001] This utility model relates to the field of vegetable planting technology, and in particular to an auxiliary device for turmeric planting. Background Technology
[0002] When harvesting ginger, farmers use a tool with serrated teeth, raising one end high and then forcefully slamming it down to insert the teeth into the soil containing the ginger. They then lift the other end of the tool upwards to dig the teeth out of the soil, simultaneously excavating the ginger and turning over the soil. Existing serrated teeth for digging and harvesting ginger have the following problems: The fulcrum is usually fixed, and when the entry point deviates, digging becomes laborious. To solve these problems, Chinese Patent Publication No. CN215188287U discloses a tool for digging and harvesting ginger in ginger cultivation. This tool uses a telescopic rod as the fulcrum for digging. The telescopic rod is adjustable in length, and the support height can be adjusted via a telescopic support mechanism to accommodate workers of various heights.
[0003] The aforementioned existing technology has the following problems in practical application: the telescopic pole is threaded, and the pole body needs to be rotated to adjust the length when used, which is cumbersome; when used on uneven fields, the position of the telescopic pole needs to be adjusted repeatedly, making it difficult to smoothly and quickly deploy for tilling operations. Utility Model Content
[0004] The purpose of this invention is to solve the problems of difficulty in adjusting the fulcrum of the rake teeth and the laborious digging process in the existing technology.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An auxiliary device for turmeric cultivation includes a base, a plurality of connecting rods on the base, a shovel head on each connecting rod, the shovel head being hinged to the connecting rod, a torsion spring between the shovel head and the connecting rod, a plurality of limiting blocks on the connecting rod, the limiting blocks being slidably connected to the connecting rod, a first connecting shaft connecting the limiting blocks to each other, a second connecting shaft connecting the shovel heads to each other, a limiting chamfer inside each limiting block, a positioning block on each shovel head matching the shape of the limiting chamfer, a grip rod on the base, the grip rod being threadedly connected to the base, a stepping device on the base, the stepping device being connected to the limiting blocks, and a support portion at the bottom of each limiting block.
[0007] Preferably, the shovel head is provided with a shovel blade, and the shovel blade is connected to the shovel head to form an "S" shape.
[0008] Preferably, the limiting block is provided with a gas spring support rod, the bottom of the cylinder of the gas spring support rod is sleeved on the first connecting shaft, and the piston rod of the gas spring support rod is connected to the second connecting shaft.
[0009] Preferably, the stepping device includes a foot pedal, which is hinged to the base. Rotating rods are provided on both sides of the base and connected to the base. A truss is provided between the rotating rods and connected to the foot pedal. A first connecting rod is provided on the truss and hinged to the truss. A second connecting rod is provided on the first connecting rod. A spring is provided between the second connecting rod and the first connecting rod. The second connecting rod is slidably connected to the first connecting rod and hinged to the limiting block.
[0010] Preferably, the pedal is provided with a baffle and friction texture.
[0011] Preferably, the limiting block is provided with a U-shaped groove, the second connecting rod is provided with a roller, the roller is connected to the U-shaped groove, the roller is slidably connected to the U-shaped groove, and the second connecting rod rotates around the roller as the axis.
[0012] The beneficial effects proposed by this utility model are as follows:
[0013] Before insertion into the soil, the shovel head flips under the action of the torsion spring, forming an angle with the connecting rod. When the device needs to be inserted into the soil, the operator first steps on the foot pedal, which causes the limiting block to slide along the connecting rod towards the shovel head. As the limiting chamfer gradually approaches the positioning block until it abuts against it, the angle between the shovel head and the connecting rod increases. In this normal state, the operator inserts the shovel head into the soil, with the shovel head extending below the turmeric fruit. Using the support as a fulcrum, the operator presses down on the handle to lift the turmeric fruit from the soil. During this process, the soil gradually loosens, and the shovel head is shaken, separating the fruit from the soil. Then, the force applied to the foot pedal is released, and the foot pedal is driven to reset. The shovel head resets under the action of the torsion spring, and the angle formed by the shovel head and the connecting rod clamps the fruit tightly, reducing the risk of the fruit falling off the shovel head during the separation process. During the excavation process described above, since the support is located at the bottom of the limiting block, the position of the fulcrum can be changed during the movement of the limiting block. By changing the position of the fulcrum, a suitable point of force can be adjusted to achieve the effect of improving labor saving. It should be noted that during the adjustment of the position of the support, the angle between the shovel head and the connecting rod also changes simultaneously. Depending on the configuration of different fulcrums, the angle at which the shovel head is inserted into the soil should also be different. The cooperation between the two can provide a suitable state for the operator. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figures 1 to 7An auxiliary device for turmeric cultivation includes a base 1, a plurality of connecting rods 2 on the base 1, a shovel head 3 on each connecting rod 2, the shovel head 3 being hinged to the connecting rod 2, a torsion spring 4 between the shovel head 3 and the connecting rod 2, a plurality of limiting blocks 5 on each connecting rod 2, the limiting blocks 5 being slidably connected to the connecting rod 2, a first connecting shaft 6 connecting the limiting blocks 5, a second connecting shaft 7 connecting the shovel heads 3, a limiting chamfer 8 inside each limiting block 5, a positioning block 9 on each shovel head 3, the positioning block 9 matching the shape of the limiting chamfer 8, a gripping rod 10 on the base 1, the gripping rod 10 being threadedly connected to the base 1, a stepping device on the base 1, the stepping device being connected to the limiting blocks 5, and a support part 11 at the bottom of each limiting block 5. Specifically, before the device is inserted into the soil, the shovel head 3 is flipped under the action of the torsion spring 4, forming an angle with the connecting rod 2. When the device needs to be inserted into the soil, the operator first steps on the foot pedal, which causes the limiting block 5 to slide on the connecting rod 2 towards the shovel head 3. As the limiting chamfer 8 gradually approaches the positioning block 9, until the limiting chamfer 8 abuts against the positioning block 9, the angle between the shovel head 3 and the connecting rod 2 increases. In this normal state, the operator inserts the shovel head 3 into the soil, with the shovel head 3 extending deep beneath the turmeric fruit. Using the support part 11 as a fulcrum, the operator presses down on the handle 10 to lift the turmeric fruit from the soil. During this process, the soil gradually loosens, and the shovel head 3 is shaken to separate the fruit from the soil. Subsequently, the force applied to the treading device is released, and the treading device is driven to reset. The shovel head 3 resets under the action of the torsion spring 4. The angle formed by the shovel head 3 and the connecting rod 2 clamps the fruit tightly, reducing the risk of the fruit falling off the shovel head 3 during the separation process from the soil. During the excavation process described above, since the support part 11 is arranged at the bottom of the limiting block 5, the position of the fulcrum can be changed during the movement of the limiting block 5. By changing the position of the fulcrum, a suitable point of force can be adjusted to achieve the effect of improving labor saving. It should be noted that during the adjustment of the position of the support part 11, the angle between the shovel head 3 and the connecting rod 2 also changes simultaneously. Depending on the configuration of different fulcrums, the angle at which the shovel head 3 is inserted into the soil should also be different. The cooperation between the two can provide a state suitable for the operator to use.
[0024] Specifically, the shovel head 3 is equipped with a shovel blade 12, which is connected to the shovel head 3 to form an "S" shape. The shovel head 12 is equipped with a protrusion 24. The shovel blade 12 and the shovel head 3 form an "S" shape structure. When the shovel head 3 is inserted into the soil, the angle of the shovel blade 12 will be lower than the insertion angle of the shovel head 3. This helps to reduce the risk of the shovel head 3 scratching the ginger fruit during the tilling process. At the same time, the "S" formed by the shovel blade 12 and the shovel head 3 also includes the protrusion 24, which also helps to improve the soil breaking effect during tilling operations.
[0025] Specifically, the limiting block 5 is equipped with a gas spring support rod 13. The bottom of the cylinder of the gas spring support rod 13 is sleeved on the first connecting shaft 6, and the piston rod of the gas spring support rod 13 is connected to the second connecting shaft 7. The gas spring support rod 13 is used for the quick reset of the limiting block 5. When it is necessary to release the shovel head 3 from the connecting rod 2 by 180 degrees, the limiting block 5 needs to be pushed towards the connecting rod 2. Since the positioning block 9 and the limiting chamfer 8 are wedge-shaped, there will be frictional resistance when the two wedge-shaped surfaces abut. This frictional resistance will slow down the reset speed of the shovel head 3 in flipping and pushing the limiting block 5, thus reducing the self-reset efficiency of the shovel head 3. The operator needs to actively apply force to the pedal device to push the limiting block 5 towards the connecting rod 2 to release the limitation on the shovel head 3. Therefore, the gas spring support rod 13 is arranged between the shovel head 3 and the connecting rod 2. When the shovel head 3 and the connecting rod 2 are at a 180-degree angle, the gas spring support rod 13 is in a compressed state. After the force applied by the pedal device is released, the compressed gas in the gas spring support rod 13 is released, causing its piston rod to extend. The cylinder of the gas spring support rod 13 pushes towards the connecting rod 2, driving the limiting block 5 to move until it completes its reset. The gas spring support rod 13 described above realizes the automatic reset and pushing of the limiting block 5, solving the problem of automatic reset of the shovel head 3.
[0026] Specifically, the pedal device includes a pedal 14, which is hinged to the base 1. Rotating rods 15 are provided on both sides of the base 1 and are connected to the base 1. A truss 16 is provided between the rotating rods 15 and is connected to the pedal 14. A first connecting rod 17 is provided on the truss 16 and is hinged to the truss 16. A second connecting rod 18 is provided on the first connecting rod 17. A spring 19 is provided between the second connecting rod 18 and the first connecting rod 17. The second connecting rod 18 is slidably connected to the first connecting rod 17 and is hinged to the limiting block 5. The operator applies force to the foot pedal 14. Through the hinge between the foot pedal 14 and the base 1, the foot pedal 14 flips relative to the base 1. The truss 16 is connected to the foot pedal 14. With the connection of the rotating rod 15, the truss 16 can stably flip synchronously with the foot pedal 14. A spring rod structure is provided between the truss 16 and the limiting block 5. When the truss 16 flips towards the shovel head 3 of the connecting rod 2, it drives the first connecting rod 17 to push towards the limiting block 5. During this process, the first connecting rod 17 pushes the second connecting rod 18 to move the limiting block 5 after compressing the spring 19. The spring rod formed by the first connecting rod 17, the second connecting rod 18, and the spring 19 can improve the mechanical structure rationality when the truss 16 is connected to the limiting block 5 and reduce the risk of excessive limitation and movement jamming when the two are connected.
[0027] Specifically, the foot pedal 14 is equipped with a baffle 20 and friction textures 21. Since this device is used in fields, the foot pedal 14 will be contaminated with soil and muddy water mixture, which may cause slippage during use. Therefore, the baffle 20 and friction textures 21 are provided to fix the foot in the position of the foot pedal 14, while increasing the friction coefficient of the foot pedal 14 and reducing the risk of slippage during use.
[0028] Specifically, the limiting block 5 is provided with a U-shaped groove 22, and the second connecting rod 18 is provided with a roller 23. The roller 23 is connected to the U-shaped groove 22 and is slidably connected to the U-shaped groove 22. The second connecting rod 18 rotates around the roller 23 as its axis. When the second connecting rod 18 pushes the limiting block 5 to move, the roller 23 slides in the U-shaped groove 22. When the roller 23 is in contact with one end face of the U-shaped groove 22, the roller 23 applies force in the U-shaped groove 22 to push the limiting block 5 towards the shovel head 3. Conversely, when the limiting block 5 returns to its original position, the roller 23 first reaches the other end face of the U-shaped groove 22 before pushing the limiting block 5 to move and return to its original position. The function of the U-shaped groove 22 is to increase the travel distance, improve the rationality and flexibility of the mechanical structure connecting the pedal 14 and the limiting block 5, and reduce the risk of excessive limitation and jamming during connection.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
