Before planting and transplanting tobacco, it is generally necessary to dig planting holes according to the plant spacing. Planting holes are also called planting holes or tree holes. Before planting seedlings, holes are dug around the designated planting point. The size of the planting hole should be determined by the planting density.

[0003] According to the Chinese patent publication number: CN220556847U, a hole-opening device for tobacco planting includes a support frame, which is used to support the side of the hole to be opened, and has a placement plate spaced from the ground; a power mechanism, which is arranged on the placement plate; a reciprocating member, which penetrates the placement plate in the up and down directions, the upper end of the reciprocating member is transmission-connected to the power output end of the power mechanism, and the lower end of the reciprocating member is connected to a horizontal push plate, and the lower end surface of the horizontal push plate is arranged with a plurality of drill bits spaced apart in the horizontal direction.

[0004] In the above scheme, a rotating drill bit is used to drill holes in the ground, which still results in the following problems: when a solid drill bit is used to drill holes in the ground, the soil will be pushed to the inner wall of the planting hole, increasing the compaction degree of the soil near the planting hole, which is not conducive to the rooting and growth of tobacco seedlings. Utility Model Content

[0005] The utility model aims to provide a hole-making device for tobacco planting, so as to solve the problem that when a drill bit drills a hole in the ground, the soil is pushed to the inner wall of the planting hole, which increases the compaction degree of the soil near the planting hole and is not conducive to the rooting and growth of tobacco seedlings.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a hole-opening device for tobacco planting, comprising a base plate, a mounting folding plate is fixed on the top surface of the base plate, a driving motor is fixed on the top surface of the mounting folding plate, a rotating hole is provided on the top surface of the mounting folding plate, the surface of the output shaft of the driving motor is rotatably inserted in the rotating hole, a sleeve hole is provided on the top surface of the base plate, a hole-opening cylinder is slidably inserted inside the sleeve hole, a threaded hole is provided on the top end of the hole-opening cylinder, a threaded rod is threadedly connected to the inside of the threaded hole, and the top end of the threaded rod is fixed to the bottom end of the output shaft of the driving motor.

[0007] Preferably, two positioning strips are fixed on the top surface of the bottom plate, and limiting grooves are respectively provided on both sides of the two positioning strips close to each other, and two limiting plates are fixed on the surface of the hole-opening cylinder, and the limiting grooves and the limiting plates are slidably arranged.

[0010] Preferably, a plurality of positioning plates are fixed to the bottom surface of the bottom plate, wherein two positioning plates form a group, and rollers are rotatably provided between each group of positioning plates.

[0011] Preferably, a push-out plate is fixed to the bottom end of the threaded rod.

[0012] Compared with the prior art, the hole-opening device for tobacco planting using the above technical solution has the following beneficial effects:

[0013] 1. The staff will first push the bottom plate to the planting point on the planting ground, and then start the driving motor. The rotating output shaft of the driving motor will drive the threaded rod to rotate. The rotating threaded rod uses the threaded connection with the threaded hole to push the hole-opening cylinder to move downward inside the socket hole. The socket hole moving downward will open a hole in the soil. During the hole-opening process, the soil that needs to be dug out of the planting hole is inside the hole-opening cylinder, and the soil is driven out of the planting hole when the hole-opening cylinder is pulled out, which prevents the soil from being squeezed on the inner wall of the planting hole, prevents the hardening degree of the soil on the inner wall of the planting hole from increasing, and is conducive to the rooting and growth of tobacco seedlings;

[0014] Second, when the hole-opening cylinder moves downward, it will drive the limit plate to move downward synchronously inside the limit groove to ensure that the hole-opening cylinder can move straight up and down. In the process of opening a hole in the soil, the staff will first place the tobacco into the placement frame, and then move the placement frame to install it on one side of the installation folding plate. At this time, the fixed folding rod is sleeved inside the fixed hole, and the placement frame can be installed on one side of the installation folding plate, which prevents frequent removal of tobacco seedlings and increases the efficiency of planting;

[0015] 3. The staff will hold their hands on the handle. At this time, the anti-slip sleeve is between the handle and the palm, and the anti-slip block is used to increase the friction between the palm and the bottom plate, and push the bottom plate to move on the ground. In the process of moving, the roller is used to reduce the friction of the bottom plate when it moves, which increases the convenience of the staff when pushing the bottom plate. Since the position of the push-out disk is fixed and located inside the hole-opening cylinder, when the hole-opening cylinder moves up, the soil in the hole-opening cylinder will be pushed out, which is convenient for cleaning the soil remaining in the hole-opening cylinder.
