[0015] Preferably, the drilling shaft is rotatably connected to the sliding seat, and the drilling shaft and the sliding seat are symmetrically distributed front and back with the left and right central axes of the supporting frame as the axis, a sliding guide rod passes through the upper end of the sliding seat, and two groups of sliding guide rods are symmetrically arranged, and both ends of the sliding guide rod are respectively fixedly connected to the first sliding block.

[0016] By adopting the above technical solution, the drilling shaft can be installed in a limited position through the design of the sliding seat, and the design of the two sets of sliding guide rods can keep the drilling shaft and the sliding seat able to slide horizontally and stably. The drilling shaft can dig holes when it is lifted, lowered and rotated, which is convenient for subsequent pepper planting.

[0017] Preferably, the first sliding block and the positioning plate are symmetrically distributed at the left and right ends of the sliding guide rod, and the first sliding block is slidably connected to the sliding groove, and the first sliding block is designed in a "T" shape.

[0018] By adopting the above technical solution, the first slider is provided with a sliding groove on the opposite side of the positioning plate, so that the stability of the vertical lifting of the sliding seat, the sliding guide rod and the first slider can be maintained.

[0026] By adopting the above technical scheme, the fertilizer can be easily discharged through the cooperation of the storage barrel, the guide pipe and the discharge pipe. After the hole is dug, the fertilizer can be discharged through the discharge hole to provide sufficient nutrition for the planted peppers.

[0027] Preferably, a baffle plate is provided inside the guide tube, and the upper end of the baffle plate extends to the outside of the guide tube, and the baffle plate is slidably connected to the guide tube, a positioning frame is fixed to the upper end of the guide tube, and a second return spring is connected to the lower end of the positioning frame, and the lower end of the second return spring is fixedly connected to the upper end of the baffle plate.

[0030] By adopting the above technical solution, through the connection between the transmission plate, the fixed plate and the first sliding block, the transmission plate can be driven to move upward while the drilling shaft is raised and lowered. When the transmission plate moves upward, the friction force and the elastic force of the reset spring can be used to drive the baffle plate to move upward, and then contact the partition of the guide plate, and the fertilizer flows down. When the transmission plate continues to move upward, the downward pressure provided by the second reset spring gradually increases. When the elastic force is greater than the elastic force of the reset spring, the second guide plate is pushed to shrink toward the inside of the baffle plate, thereby releasing the connection with the transmission plate and resetting downward to continue to isolate the guide tube.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows: the hole-digging device for pepper planting can improve the hole-digging effect by setting a rotary hole-digging structure, avoid the collapse of subsequent planting holes, and can discharge the broken soil generated by the hole-digging to the outside when the drilling shaft moves upward, thereby improving the subsequent planting effect, and is equipped with a transmission structure, so that holes can be dug during the movement without pausing, thereby improving the convenience of operation and the efficiency of hole-digging.

[0032] 1. By setting a drilling shaft that can move horizontally and vertically, and cooperating with a transmission structure, the positions of the drilling shaft and the support frame can be adjusted accordingly during the movement of the drilling device, so that the drilling device does not need to stop during the movement and still maintains the vertical lifting movement of the drilling shaft;

[0033] 2. By providing a fertilizer feeding mechanism, fertilizer can be fed into the dug hole after the hole is dug, so as to reduce the time required for manual fertilization and provide sufficient nutrients for the subsequent growth of peppers. The feeding of fertilizer can be controlled by the lifting of the drilling structure, and the feeding can be quantitative and the feeding position can be accurately controlled to avoid waste.

Belt 15, during the movement of the hole-digging device, the second transmission wheel 5 drives the transmission shaft 4 to rotate, and the transmission shaft 4 drives the second pulley 33 to rotate. When the second pulley 33 rotates, the transmission belt 15 drives the first pulley 13 and the transmission turntable 12 to rotate synchronously. Because the transmission turntable 12 and the transmission rod 14 are eccentrically connected, the transmission rod 14 makes a circular motion around the center of the transmission turntable 12 when the transmission turntable 12 rotates, and the diameter of the transmission turntable 12 is the same as the diameter of the second transmission wheel 5, so as to maintain the stability of the operation of the subsequent drilling structure.

The limit ensures that the drilling shaft 10 remains in an upright state. The cooperation of the sliding seat 11 and the sliding guide rod 9 can stably move horizontally, and the cooperation of the first sliding block 8 and the sliding groove can stably lift and lower vertically. The relative position of the drilling shaft 10 to the support frame 1 is constantly changing. When the hole digging device is moving, when the transmission rod 14 moves to the leftmost end of the transmission turntable 12, the lower end of the drilling shaft 10 contacts the ground, and when the transmission turntable 12 continues to rotate, the drilling shaft 10 drills downward, and when the hole digging device continues to move, the transmission turntable 12 can drive the transmission rod 14 and the sliding seat 11. The position of the drilling shaft 10 relative to the support frame 1 moves backward in the forward direction of the device, and the horizontal position relative to the ground does not change to avoid trenching. The drilling shaft 10 continues to drill downward, but the movement of the hole digging device is not affected, and it is also not affected when it moves upward after the hole digging is completed. The hole digging device can be controlled to move at a uniform speed to perform hole digging operations.

The distance that the second transmission wheel 5 rolls is L2, and L1 is equal to L2, so that when the fertilizer is fed, the feeding pipe 25 and the dug hole are in the same position to ensure that the fertilizer can accurately fall into the hole to be planted, and the hole opened by the drilling shaft 10 is larger than the feeding pipe 25, which further prevents the fertilizer from falling into the outside of the hole, and when the transmission plate 32 continues to move upward, the second compound is gradually The first guide plate 29 is pushed to retract into the baffle plate 34 when the elastic force of the second return spring 28 is greater than the friction force and the elastic force of the return spring 30 after compression, and the baffle plate 34 is pushed downward by the second return spring 28 to continue to block the guide tube 24, so as to avoid the waste of fertilizer leakage during the process, reduce the time required for manual fertilization, provide sufficient nutrients for the subsequent growth of peppers, and control the feeding of fertilizers by the lifting of the drilling structure. ;
