Description

Technical Field

[0001] The invention relates to the technical field of oil-tea planting equipment, and in particular to an automatic pit digging device used for oil-tea planting. Background Art

[0002] The seeds of Camellia oleifera can be used to extract oil, which is not only edible, but also used in industry as lubricating oil and anti-rust oil. Its tea cakes are both pesticides and fertilizers, which can improve the water storage capacity of farmland and prevent rice field pests. Therefore, Camellia oleifera is a suitable economic crop.

[0003] When planting large areas of tea oil seedlings, mechanical digging is often used. In the prior art, many digging equipment uses a digging drill bit with spiral blades to dig holes, such as patent CN220935576U and patent CN116076324A. The digging drill bit digs the hole by rotating downward to bring out the soil in the ground. After digging the hole, soil will remain between the spiral blades of the digging drill bit. The general digging drill bit will throw out this part of the soil by rotating. Some digging equipment can not only dig holes, but also have plant planting and filling functions, such as patent CN219938907U.

[0004] When the tea oil plant is planted in a pit, the root system needs to be kept naturally stretched downward. Therefore, when filling the soil, the rhizomes of the tea oil plant need to be covered with loose fine soil first, and then the tea seedlings are gently lifted up to stretch the root system, and finally the soil is compacted. The pit digging device in the prior art directly pushes the excavated soil into the planting pit when filling the soil. If the soil is sometimes agglomerated in large quantities, the soil may break the rhizomes of the tea seedlings and cause the rhizomes to be unable to stretch, affecting the growth and survival rate of the tea seedlings. Summary of the invention

[0005] The present invention combines the function of a spiral pit-digging drill bit to bring out soil and the need for filling soil when planting tea oil plants, and proposes an automatic pit-digging device for oil tea planting. After the pit-digging drill bit digs the pit, the soil between the spiral blades of the pit-digging drill bit is finely crushed to meet the filling soil requirement for planting tea oil plants. At the same time, the tea oil plants can be pulled after filling the soil to keep the roots of the tea oil plants stretched after planting, which is beneficial to the survival and growth of the tea oil plants.

During the digging process, part of the soil is discharged to the ground by the spiral blade 201, and after the digging is completed, part of the soil remains in the spiral blade 201;

[0062] Step 3: Turn off the rotating motor 16, and the adjusting cylinder 13 drives the adjusting rod 12 to make the connecting seat 11, the second slide rail 5, the digging seat 3 and the digging drill bit 2 move vertically upward, and the spiral piece 201 brings the soil in the pit out. At this time, the second slide rail 5 is combined with the first slide rail 4 and the third slide rail 6 again;

[0063] The sealing cylinder 31 drives the sealing cover 32 to move, so that the sealing cover 32 is separated from the joint surface of the driving wheel 202;

[0064] Step 4: The first sliding cylinder 42 drives the first sliding block 41 to move close to the pit digging seat 3, and the second sliding cylinder 62 drives the second sliding block 61 to move close to the pit digging seat 3. The first sliding block 41 and the second sliding block 61 move to the corresponding limit positions. Figure 6 The first shell 7 and the second shell 8 form a combined box, which wraps the pit-digging drill bit 2 and is used to store the soil brought out by the pit-digging drill bit 2;

[0065] Step 5: Start the rotating motor 16, the rotating motor 16 drives the hole digging drill bit 2 to rotate forward, the spiral blade 201 drives the soil to move upward to achieve stirring, and the crushing blade 15 crushes the soil inside the combined box to form finely crushed soil inside the combined box;

[0066] Step 6: Turn off the rotating motor 16, the first sliding cylinder 42 drives the first sliding block 41 to move away from the digging seat 3, and the second sliding cylinder 62 drives the second sliding block 61 to move close to the digging seat 3, and the clamping member 91 of the planting conveying body 9 is moved to the top of the planting pit while keeping the first shell 7 and the second shell 8 in the combined state;

[0067] Step 7: Reference Fig.13 , clamp the plant on the clamping member 91, the coupling cylinder 171 drives the coupling wheel 17 to move, the coupling cylinder 171 is coupled with the first coupling wheel 18 and the driving wheel 202, and the coupling wheel 17 connects the power transmission component and the driving wheel 202.

[0069] Step 8: When the start plate 92 contacts the sensor 83, the root of the plant is located at a suitable position in the planting pit, the clamping member 91 is located below the movable guide plate 85, and the sensor 83 senses the opening signal, the discharge valve 821 opens, and the soil inside the combined box enters the planting pit through the discharge pipe 82 for filling; at the same time, the electromagnetic block of the adsorption positioning plate 84 is energized to generate magnetic attraction, which can adsorb the start plate 92 to achieve the positioning of the start plate 92;

[0070] After the start plate 92 is positioned, the combination cylinder 171 drives the combination wheel 17 to move, and the combination cylinder 171 leaves the first connection wheel 18 and the driving wheel 202. The clamping member 91 clamps the plant to be stably located in the planting pit, and the rotary motor 16 rotates in the reverse direction, the pit-digging drill bit 2 rotates, and the spiral piece 201 of the pit-digging drill bit 2 moves the soil downward, so that the soil inside the combination box can all enter the planting pit;

The second guide block 852 first pushes the movable sleeve 915 to move in the direction close to the movable seat 913 to achieve the clamping member 91 to loosen the clamping of the planting. Then the first guide block 851 pushes the movable seat 913 to move in the direction close to the fixed plate 911. Under the condition of keeping the clamping loose, the clamping block is separated from the main trunk of the plant to prevent the clamping block from clamping the plant again.

[0073] Step 10: After the implantation transmission body 9 is completely returned to its original position, the guide cylinder 86 drives the movable guide plate 85 to move backward, and the movable guide plate 85 leaves the clamping member 91;
