Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0032] It should be noted that all the directional indications in the embodiments of the present application are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture. If the specific posture changes, the directional indication will also change accordingly.

For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0034] In addition, in the present application, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0035] In the related art, hard objects such as stones and tree roots are unevenly distributed in the soil, and no buffer structure is provided at the position of the blade in the existing soil loosening device, resulting in the blade directly bearing the impact of hard objects and reducing the service life of the blade. Therefore, a soil loosening device for agricultural planting with a blade buffer is proposed.

[0036] To solve the problems in the related art to a certain extent, the embodiments of the present application provide a soil loosening device for agricultural planting. When the blade encounters a hard object during rotation, the blade will squeeze the spring, change the position of the blade on the disc body, thereby reducing blade damage, and then the elastic reset of the spring moves the blade to the initial position of the disc body.

[0037] The present application will be described below in conjunction with the accompanying drawings and with reference to specific embodiments:

[0038] In combination withFigures 1-7 , an embodiment of the present application provides a soil loosening device for agricultural planting, including a frame 100. A connecting frame 110 is fixedly connected to the top of the frame 100. A transmission assembly 200 is arranged on the connecting frame 110. A second shaft 420 is rotatably connected to the inner side wall of the frame 100. The transmission assembly 200 drives the second shaft 420 to rotate. One end of the second shaft 420 is fixedly connected to a first shaft 400. The first shaft 400 is rotatably connected to the frame 100. A plurality of discs 410 are arranged on the outer side wall of the first shaft 400. A plurality of buffer assemblies are arranged on one side of the disc 410. A blade 450 is fixed on the buffer assembly. When the blade 450 hits a hard object, the buffer assembly changes the position of the blade 450 on the disc 410.

[0039] Specifically, the connecting frame 110 is connected to the vehicle body. The suspension device on the vehicle body is used to change the depth of the entire frame 100 in the soil. The vehicle body is used to connect to the transmission assembly 200. When loosening the soil, the transmission assembly 200 is driven. The transmission assembly 200 drives the second shaft 420 to rotate. The second shaft 420 drives the first shaft 400 to rotate, thereby driving a plurality of blades 450 to rotate. The plurality of blades 450 are used to break up the soil. During the breaking-up process, if the blade 450 encounters a hard object such as a stone, the blade 450 presses the first connecting rod 470, causing the first connecting rod 470 to slide on the first housing 430 and compress the spring 480. Due to the compression of the spring 480, the impact force is weakened, thereby reducing the damage caused by the hard object to the blade 450. The vehicle body and the suspension device are not shown in the drawings and belong to the prior art, so they will not be elaborated here.

[0040] Combined with the attached Figure 4 , in some embodiments, a sliding groove for sliding the disc 410 is formed on the first shaft 400. A spring is arranged in the sliding groove. The spring is fixedly connected to the sliding groove and one side surface of the disc 410 respectively.

[0041] Specifically, a plurality of sliding grooves are formed on the outer side of the first shaft 400. The inner side wall of the disc 410 is provided with sliding blocks that cooperate with the sliding grooves. The sliding blocks slide in the sliding grooves. Springs are arranged on both side surfaces of the sliding blocks. The springs are fixed to the sliding grooves. The disc 410 can slide on the first shaft 400. Therefore, when the disc 410 encounters a hard object, the disc 410 slides on the first shaft 400 by the buffering of the spring, thereby weakening the impact force and reducing the damage to the blade 450 and the disc 410. The spring, the sliding groove, and the sliding block are not shown in the drawings and are common structures.

[0042] Combined with the attached Figures 4-6, in some embodiments, a limiting component is provided on the inner side wall of the frame body 100. The limiting component penetrates through the first shaft body 400, and when the position of the blade 450 changes, it moves on the limiting component, causing the disc body 410 to move within the sliding groove.

[0043] Specifically, the limiting component is used to limit the position of the disc body 410 on the first shaft body 400. When the blade 450 encounters a hard object during the process of rotating and loosening the soil, the blade 450 will move towards the limiting component and slide on the limiting component, thereby changing the position of the disc body 410 on the first shaft body 400, and further linking the displacement of the disc body 410, further reducing the damage to the blade 450 and the disc body 410.

[0044] In some embodiments, the buffer component includes: a first housing 430, which is fixed to one side of the disc body 410; a second housing 440, which is arranged on the first housing 430. A first connecting rod 470 is slidably connected to the first housing 430. A first plate body 460 is fixed to the outer side wall of the first connecting rod 470. A spring 480 is arranged between the first plate body 460 and the first housing 430. One end of the first connecting rod 470 is fixedly connected to the blade 450.

[0045] Specifically, when the blade 450 receives an impact, the blade 450 will drive the first connecting rod 470 to slide on the first housing 430, and at the same time drive the first plate body 460 to compress the spring 480, and the impact force is weakened by the elasticity of the spring 480.

[0046] Combined with the attached Figure 6 , in some embodiments, the limiting component includes: a third shaft body 520, which is arranged on the first shaft body 400; an extrusion block 510, which is arranged on the outer side wall of the third shaft body 520, and the extrusion block 510 has four inclined surfaces.

[0047] Specifically, when the first connecting rod 470 is driven to move by the blade 450, the first connecting rod 470 moves from the high point of the inclined surface of the extrusion block 510 to the low point, thereby changing the position of the disc body 410 on the first shaft body 400. In the attached Figure 6 , the first connecting rod 470 is only connected to one extrusion block 510, and it is not limited to one extrusion block 510. It can be symmetrically arranged extrusion blocks 510, so that the disc body 410 can move left or right on the first shaft body 400.

[0048] Combined with the attached Figure 6 , in some embodiments, a sleeve 530 is arranged on the outer side wall of the third shaft body 520. The sleeve 530 is fixedly connected to the first shaft body 400. The third shaft body 520 can slide within the sleeve 530. A driving component for driving the third shaft body 520 to reciprocate is arranged on the frame body 100, and the driving component is rotationally connected to the third shaft body 520.

[0049] Specifically, after the entire device is used up, by controlling the driving component, the driving component drives the third shaft 520 to reciprocate within the first shaft 400, thereby driving the second connecting rod 500 to move on the extrusion block 510. The second connecting rod 500 moves from the low point to the high point of the inclined surface of the extrusion block 510, causing the second connecting rod 500 to squeeze the second housing 440. At this time, the second housing 440 squeezes the outer wall of the blade 450, scraping off the sludge on the outer wall of the blade 450. A spring is fixed between the second housing 440 and the first plate 460 to reset the second housing 440 driving the second connecting rod 500. The spring is not shown in the drawings. When the blade 450 drives the first connecting rod 470 to move, the second housing 440 can also clean the outer wall of the blade 450, thereby reducing the cleaning difficulty of the blade 450.

[0050] Combined with the attached Figure 6 and 7 In some embodiments, the driving component includes a box body 570. The box body 570 is fixed to the bottom of the frame body 100. A commutator 550 is fixed inside the box body 570. One side of the commutator 550 is rotatably connected to a fourth shaft 560, and the bottom end is rotatably connected to a connecting rod assembly 540. A slider is connected to the connecting rod assembly 540, and the slider is rotatably connected to the third shaft 520.

[0051] Specifically, the fourth shaft 560 can be connected to an external driving force. The fourth shaft 560 drives the commutator 550 to work. The commutator 550 changes the output direction and drives the connecting rod assembly 540 to rotate. The connecting rod assembly 540 drives the slider to reciprocate. At this time, the third shaft 520 moves on the sleeve 530, and the third shaft 520 changes the positions of multiple extrusion blocks 510, thereby causing the second connecting rod 500 to expand and contract, changing the position of the second housing 440 on the outer wall of the blade 450, and cleaning the outer wall of the blade 450. The commutator 550 includes a first bevel gear and a second bevel gear that mesh with each other, and the rotation direction is changed by the bevel gear method.

[0052] Combined with the attached Figures 1-7 In some embodiments, a water spraying component is provided at the bottom of the frame body 100. The water spraying component includes a water distribution pipe 310. The water distribution pipe 310 is fixedly connected to the bottom of the frame body 100. A water inlet pipe 320 is fixed to the top of the water distribution pipe 310, and water pipes 300 are fixed on both sides. A plurality of nozzles 330 are provided on the water pipes 300. A spiral blade is rotatably connected inside the water distribution pipe 310. The bottom end of the spiral blade penetrates through the water distribution pipe 310. A commutator is fixed to the bottom of the water distribution pipe 310. The spiral blade is fixedly connected to the commutator, and the fourth shaft 560 is fixedly connected to the commutator.

[0053] Specifically, when encountering a dry ground or when it is necessary to clean the blade 450, the water inlet pipe 320 is externally connected to a water source. The water is distributed into the two water pipes 300 by the water distribution pipe 310, and the water is ejected by multiple nozzles 330. When the water flows in the water distribution pipe 310, it drives the rotation of the spiral blade, and the spiral blade drives the commutator to rotate. The commutator changes the rotation direction and transmits it to the shaft body four 560. Therefore, the reciprocating motion of the shaft body three 520 can be linked. During the water spraying process, the housing two 440 cleans the outer wall of the blade 450.
