Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, specifically to a land tillage device. Background Technology
[0002] Tillage refers to the process of shoveling, breaking up, and loosening the land to make it level and loose. It is the most basic process in farming, allowing seeds to breathe and grow easily in the soil. When land needs tillage, tillers are often used. Tillers use plow blades to turn the land. However, since the land to be tilled contains a lot of weeds, if the tiller is used directly, the weeds may become entangled on the surface of the plow blade's rotating rollers. As the weeds become too entangled, it will affect the subsequent use. Therefore, we have proposed a land tillage device to solve the above-mentioned problems. Utility Model Content
[0003] The purpose of this invention is to provide a land tillage device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a land tillage device, comprising a tillage machine body, and further comprising: The rotary plow blades are installed at the bottom of the tiller body, and a crash bar is fixedly connected to one side of the tiller body; It features an adjustable mowing mechanism located below the bumper bar; An interceptor structure used to guide the cut weeds is located below the bumper.
[0005] Preferably, the mowing structure includes a first fixing plate fixedly connected to the inner side of the anti-collision bar, a threaded rod rotatably connected to the inner side of the first fixing plate, a threaded sleeve threadedly connected to the surface of the threaded rod, a second fixing plate fixedly connected to the surface of the threaded sleeve, a torsion plate fixedly connected to the top of the threaded rod, and a weeding mechanism disposed below the second fixing plate.
[0006] Preferably, the weeding mechanism includes a first support rod fixedly connected to the bottom end of the second fixed plate, a first support plate fixedly connected to the bottom end of the first support rod, a blade provided on one side of the first support plate, and fixing components for assembling and disassembling the blade provided on both the front and rear sides of one side of the first support plate.
[0007] Preferably, the fixing assembly includes a plurality of third fixing plates fixed to one side of the first support plate, and the internal threads of the third fixing plates are connected to fixing bolts.
[0008] Preferably, the interception structure includes a second support rod fixedly connected to the bottom end of the second fixed plate, a third support plate fixedly connected to the bottom end of the second support rod, and a baffle fixedly connected to one side of the third support plate.
[0009] Preferably, a second support plate is fixedly connected to one side of the second fixing plate, and the top of the second support plate is slidably connected to the interior of the first fixing plate.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: Before tilling the land, this invention allows the second fixed plate to move by connecting the surface of the threaded rod with the threaded connection inside the second fixed plate, thereby adjusting the position of the blades. This enables the tiller to remove weeds during tilling, and the interception structure guides the cut weeds to the sides of the rotary plow blades, preventing them from entering the interior of the blades.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Please see Figure 1-5 As shown, a land tillage device includes a tiller body 1, a rotary plow blade 2 at the bottom of the tiller body 1, a bumper bar 3 fixedly connected to one side of the tiller body 1, and an adjustable mowing structure 4 installed below the bumper bar 3. The mowing structure 4 includes a first fixing plate 41 fixedly connected to the inner side of the bumper bar 3, a threaded rod 42 rotatably connected to the inner side of the first fixing plate 41, a threaded sleeve 43 threadedly connected to the surface of the threaded rod 42, a second fixing plate 44 fixedly connected to the surface of the threaded sleeve 43, and a torsion plate 45 fixedly connected to the top of the threaded rod 42. It also includes a weeding mechanism 46 located below the second fixing plate 44. Through the mowing structure 4, the operator can... Rotating the torsion disc 45 can drive the threaded rod 42 to rotate and drive the weeding mechanism 46 to move downward, so as to be more convenient and flexible to be applied to various working environments. The weeding mechanism 46 includes a first support rod 461 fixedly connected to the bottom end of the second fixed plate 44. The bottom end of the first support rod 461 is fixedly connected to a first support plate 462. A blade 463 is provided on one side of the first support plate 462. Fixing components 464 for assembling and disassembling the blade 463 are provided on both the front and rear sides of one side of the first support plate 462. With the setting of the weeding mechanism 46, when the tiller body 1 is working, the blade 463 can clean up weeds and prevent weeds and other impurities from getting stuck in the rotary plow blade 2.
[0015] An interception structure 6 is used to guide the cut weeds. The interception structure 6 includes a second support rod 61 fixedly connected to the bottom end of the second fixed plate 44. A third support plate 62 is fixedly connected to the bottom end of the second support rod 61. A baffle 63 is fixedly connected to one side of the third support plate 62. By setting the interception structure 6, the baffle 63 can move up and down simultaneously with the weeding mechanism 46. The baffle 63 is set at an angle, so that the cut grass can be concentrated and guided to both sides of the tiller body 1, preventing weeds from entering the interior of the rotary plow blades 2.
[0016] The fixing component 464 includes several third fixing plates 4641 fixed to one side of the first support plate 462. The internal threads of the third fixing plates 4641 are connected to fixing bolts 4642. With the setting of the fixing component 464, after the blade 463 has been used multiple times, the operator can rotate the fixing bolts 4642 to disassemble and replace the blade 463, thereby ensuring the stable operation of the weeding mechanism 46.
[0017] A second support plate 5 is fixedly connected to one side of the second fixed plate 44, and the top of the second support plate 5 is slidably connected to the inside of the first fixed plate 41. The second support plate 5 can guide the movement of the second fixed plate 44 and maintain the stability of the second fixed plate 44 when it moves downward.
[0018] Working principle: Before using the tiller, the operator first rotates the torsion disc 45, which drives the threaded rod 42 to rotate. Simultaneously, the threaded sleeve 43 on the surface of the threaded rod 42 moves downwards, causing the second fixed plate 44 on its surface to move as well. With the movement of the second fixed plate 44, the first support rod 461, the second support rod 61, the third support plate 62, the first support plate 462, and the baffle 63 move, causing the protruding ridge at the bottom of the baffle 63 to contact the ground, while the first support plate 462 moves closer to the ground. When the baffle 63 and the first support plate 462 are adjusted... Once in the appropriate position, the operator can start the tiller body 1, causing the rotary plow blades 2 at the bottom of the tiller body 1 to begin tilling the land. During tilling, the blades 463 can cut the weeds in the land. The cut weeds will fall to the ground. As the tiller body 1 continues to move, the baffle 63 can guide the cut weeds, so that the weeds are located on both sides of the rotary plow blades 2. When the blades 463 wear out after repeated use, the operator can use a wrench to loosen the fixing bolt 4642 in the third fixing plate 4641, so that the blades 463 can be removed and replaced.
