Description

Technical Field

[0001] This utility model relates to the field of planting equipment, and more specifically to a sandy soil perforation and sowing device. Background Technology

[0002] In arid and semi-arid regions, where natural rainfall is scarce and surface desertification is severe, the soil is highly mobile and permeable due to the lack of plant roots, leading to serious desertification. To prevent the expansion of these areas, it is necessary to sow seeds and cultivate plants to stabilize the sandy soil and prevent severe soil erosion.

[0003] Due to severe soil desertification and excessive soil mobility in the aforementioned areas, coupled with uneven surfaces and the presence of weathered gravel, manual sowing is typically employed. However, given the large area to be sown, manual sowing is extremely inefficient. Existing automated sowing equipment is limited in function, requiring separate equipment for land preparation, excavation, and sowing. Furthermore, existing equipment is unsuitable for this region due to the uneven surface and numerous impurities, making sowing prone to interruption. Additionally, the high soil mobility means that after trenching, the soil around the trenches can easily slip before the seeds have a chance to fall in, resulting in shallow seed burial despite deep trenches or pits. When the topsoil is blown away by the wind, the seeds may also be blown out of the trenches or pits or exposed directly on the surface, thus affecting survival rates.

[0004] Therefore, how to provide a sand-drilling and seeding device that can overcome the above-mentioned problems is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

When the handrail 3 is pulled up, the cleaning tooth 23 is in contact with the ground, and the rotating cleaning tooth 23 in combination with the forward and backward movement of the frame 1 can realize the cleaning of the ground impurities and the flattening of the ground. When the handrail 3 is pressed down, the cleaning tooth 23 is out of contact with the ground, and the rotating drill pipe 5 and spiral tooth 7 are in contact with the ground, thereby realizing the drilling of the ground which has been cleaned and flattened. At the same time, in combination with the design of the conical plug 8, the pull rod 9, the telescopic cylinder 10 and the hopper 11, when the drilling is completed and the drill pipe 5 is about to be pulled up, the telescopic cylinder 10 can drive the conical plug 8 to move downward, and the seeds in the hopper 11 can fall into the drilled hole from the lower end of the drill pipe 5, thereby realizing the seeding operation. In addition, when the drilling is completed and the drill pipe 5 is pulled up, the drill pipe 5 and the spiral tooth 7 are both in a rotating state, and during the process of separating from the hole, the soil outside the hole will not fall into the drilled hole in large quantities, ensuring that the seeds have sufficient arrangement and burying depth.

[0032] By designing the supporting shaft 13, the mounting hole and the jack, even if the frame 1 is on an inclined ground, the drill rod can be vertically arranged, ensuring the drilling effect.

[0033] By designing the installation cylinder 18, the seeding roller 19 and the driving machine three 20, the pit 190 can contain one or more seeds at a time, the driving machine three 20 drives the seeding roller 19 to stop rotating after rotating a certain angle, and when the seeding roller 19 stops rotating each time, one pit 190 is opposite and communicates with the seed inlet position and one pit 190 is opposite and communicates with the seed outlet position, when the pit 190 containing seeds is opposite to the seed outlet position, the seeds in the pit 190 will fall into the seed outlet pipe 12 and finally slide into the annular gap, which ensures that the number of seeds falling into each drilled hole is constant, avoiding uneven seeding;

[0034] By designing the circular truncated cone body 21, the design ensures that the seeds in the drill pipe 5 can smoothly fall out of the lower end of the drill pipe 5;

[0035] By designing the limiting cylinder 16 and the stopper 17, the telescopic cylinder 10 drives the tapered plug 8 to move and the driving machine one 6 drives the drill pipe 5 to rotate without interfering with each other;

[0036] The seeding device integrates the functions of ground cleaning, leveling, drilling and seeding, has high seeding operation efficiency, and can perform seeding operation in a complex ground environment.

[0059] When the perforating and sowing device is running:

[0060] The user holds the handrail 3 and pushes the frame 1 to move forward, and the user keeps pressing or pulling the handrail 3 while pushing the frame 1 to move, so as to ensure that the cleaning teeth 23 or the conical plug 8 will not contact the ground, and the frame 1 can move flexibly.

[0061] When the frame 1 moves to the designated area:

[0062] Firstly, the user starts the driving machine two 24 by using the switch 25, the driving machine two 24 drives the cleaning teeth 23 to rotate, then the user lifts and pushes the handrail 3, so that the rotating cleaning teeth 23 contact the ground of the designated area, the cleaning teeth 23 clean and flatten the ground of the designated area, and after the cleaning and flattening are completed, the user controls the switch 25 to stop the driving machine two 24.

[0063] Secondly, the user continues to push the frame 1 to move forward by a distance, so that the drill pipe 5 corresponds to the position of the ground which has been cleaned and flattened, then the user starts the driving machine one 6 by using the switch 25, the drill pipe 5 and the helical teeth 7 rotate, the operator presses the handrail 3, the drill pipe 5 and the helical teeth 7 drill holes in the ground which has been cleaned and flattened, and it should be noted that the telescopic cylinder 10 is in a retracted state at this time, and the large-diameter end of the conical plug 8 is in close contact with the lower end of the drill pipe 5.

[0064] Third step, after the hole is drilled to a certain depth, the drill pipe 5 and the helical teeth 7 are kept rotating, the user starts to move the handle 3 upwards, at the beginning of moving the handle 3 upwards, the user starts the driving machine three 20 and the telescopic cylinder 10 in sequence by using the switch 25, the driving machine three 20 drives the seeding roller 19 to rotate for a certain angle and then stop, the seed in the one concave pit 190 will fall into the annular gap, the telescopic cylinder 10 performs the extension action, the conical plug 8 is separated from the lower end of the drill pipe 5, the seed in the annular gap will move out from the lower end of the drill pipe 5 and fall into the hole which has been drilled;

[0065] Fourth step, after the drill pipe 5 is completely extended out of the hole, the driving machine three 20 and the telescopic cylinder 10 are turned off and reset, the user presses or pulls the handle 3 downwards or upwards, so that the cleaning teeth 23 or the conical plug 8 will not contact the ground, then the user pushes the frame 1 to move, so as to drill and seed the next hole;

[0066] The present application only relates to cleaning, leveling, drilling and seeding the ground, after the seed falls into the drilled hole, there are three subsequent processing methods:

[0067] The first method is to manually fill the hole with the seed by using a tool;

[0068] The second method is to install two V-shaped scrapers below the handle 3, the plate surface of the scraper is arranged vertically, the scraper is located between the drill pipe 5 and the handle 3, when the frame 1 moves forward, the floating soil removed from the hole during the drilling process will be limited between the two scrapers, with the forward movement of the scraper, the two scrapers will refill the floating soil removed from the hole during the drilling process; in this case, a driving device needs to be installed on the walking wheel 2, otherwise it is not easy to push the frame 1 by relying on manpower, for example, a hub motor is coaxially installed on the walking wheel 2, the fixed shaft of the hub motor is fixed with the frame 1, the body of the hub motor is fixed with the walking wheel 2, the hub motor is electrically connected with the controller 26, and the hub motor can drive the walking wheel 2 to rotate after being powered on, so as to drive the frame 1 to move forward or backward;

[0069] The third method is to rely on the soil quality of the seeding area, that is, the present application is applied to sandy land, the soil quality of the sandy land is soft and the soil has good fluidity, because the seeding process is completed when the rotating drill pipe 5 has not moved out of the hole, when the drill pipe 5 completely moves out of the hole, the soil on the hole wall will slide down due to the fluidity and gravity of the soil, so as to realize the covering of the seed in the hole.

[0070] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same or similar parts between the various embodiments can be referred to each other.
