[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] Reference Figures 1 to 3 As shown, the rotary tillage and ridging device of this utility model can be applied to ridging in paddy fields to form ridges suitable for planting crops. Specifically, the rotary tillage and ridging device includes a frame 100, a rotary tillage shaft 200, a ridging assembly 300, and an adjustment assembly 400.

[0032] Reference Figure 1 , Figure 2 and Figure 3 As shown, the frame 100 includes a rotary tillage space 110. The frame 100 can be connected to an external walking device, such as having its front end towed onto a vehicle. The frame 100 moves through the field via the vehicle. The front end of the rotary tillage space 110 is open, allowing soil to enter as the vehicle moves. The rotary tillage shaft 200 then turns the soil within the rotary tillage space 110.

[0033] Reference Figure 1 , Figure 2 and Figure 3As shown, specifically, the rotary tillage shaft 200 is located within the rotary tillage space 110. The rotary tillage shaft 200 includes a shaft body 210 and two rotary tillage blades 220. The shaft body 210 is rotatably connected to the frame 100. Under the drive of the vehicle body or external drive mechanism, the shaft body 210 and the frame 100 can rotate relative to each other to realize the rotary tillage action of the rotary tillage shaft 200 on the soil within the rotary tillage space 110.

[0034] Reference Figure 1 , Figure 2 and Figure 3 As shown, the two ends of the shaft 210 are arranged in the left and right direction, and two rotary tillage blades 220 are connected in sequence in the axial direction. The rotary tillage blades 220 are arranged in a spiral around the shaft 210. By rotating the shaft 210, the rotary tillage blades 220 can agitate the soil layer to loosen the soil. The two rotary tillage blades 220 rotate in opposite directions. Under the conveying action of the spiral, the loosened soil in the rotary tillage space 110 can be gathered towards the middle of the shaft 210.

[0035] Reference Figure 1 , Figure 2 and Figure 3 As shown, the adapted ridging assembly 300 includes an upper scraper 320 and two side plates 310 connected to the rear end of the frame 100. The upper scraper 320 and the two side plates 310 together form a ridging channel 330, which is arranged to run through the front and rear. The ridging channel 330 is connected to the rotary tillage space 110 and is positioned opposite to the middle of the shaft 210. Under the spiral conveying action of the rotary tillage shaft 200, the soil transported to the middle of the shaft 210 enters the ridging channel 330 under the restricting and shaping action of the upper scraper 320 and the side plates 311. The side plates 310 are used to form the side walls of the ridge, and the upper scraper 320 is used to form the top surface of the ridge. That is, under the joint restricting action of the side plates 310 and the upper scraper 320, the soil is shaped into a ridge. This rotary tillage and ridging equipment, through the cooperation of the rotary tillage shaft 200 and the ridging component 300, can improve the ridging effect, making the formed ridges more regular and helping to avoid the problem of sparse soil in some areas of the ridge.

[0036] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, the rotary tillage ridging equipment also includes an adjustment component 400, which is used to move the two side plates 310 closer to or further away from the center of the shaft 210 to adjust the width between the two side plates 310, thereby adjusting the width of the formed ridge and improving its applicability to different crops and planting scenarios.

[0037] Reference Figure 1 , Figure 2 and Figure 3As shown, it is understandable that in order to further improve the soil breaking capacity of the rotary tillage shaft 200, so as to loosen the soil and reduce the problem of the rotating shaft 510 getting stuck, the rotary tillage and ridging equipment has multiple stirring blocks 230 connected to the rotary tillage shaft 200 along its axial direction, and the stirring blocks 230 and the rotary tillage blades 220 are arranged at intervals.

[0038] Specifically, the rotary tiller blade 220 and the agitator block 230 can be fixed to a predetermined position on the shaft 210 by welding. The radial extension length of the agitator block 230 along the shaft 210 is less than the radial extension length of the rotary tiller blade 220 along the shaft 210, so as to achieve a staggered arrangement of the agitator block 230 and the rotary tiller blade 220.

[0039] Reference Figure 1 , Figure 2 and Figure 3 As shown, when the shaft 210 rotates, the rotary tillage and ridging equipment can loosen the soil by agitating the soil with the stirring block 230. Combined with the rotation of the rotary tiller blade 220, the agitation effect on the soil can be improved, and the loosened soil can be transported to the middle of the shaft 210. Under the shaping action of the ridging component 300, the loosened soil can be shaped into a ridge. The setting of the rotary tillage shaft 200 can improve the agitation effect on the soil and the amount of soil that converges into the ridging channel 330, thereby improving the ridging effect.

[0040] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that the stirring block 230 includes a first sub-block 231 and a second sub-block 232. Both the first sub-block 231 and the second sub-block 232 are fixedly connected to the shaft 210, and the first sub-block 231 and the second sub-block 232 are centrally symmetrical about the shaft 210.

[0041] Reference Figure 1 , Figure 2 and Figure 3 As shown, the first sub-block 231 and the second sub-block 232 are arranged in opposite directions, and the first sub-block 231 and the second sub-block 232 are fixedly connected to the two sides of the shaft 210 respectively. When the shaft 210 rotates, the first sub-block 231 and the second sub-block 232 located in the same axial position of the shaft 210 can loosen the soil together. With the rotation of the rotary tiller 220, the soil agitation effect can be improved, and the loosened soil can be transported to the middle of the shaft 210.

[0042] Reference Figure 1 , Figure 2 and Figure 3As shown, it can be understood that two axially adjacent stirring blocks 230 are arranged at an angle. That is, multiple stirring blocks 230 are staggered rather than parallel. When the shaft 210 rotates, the stirring blocks 230 located at different positions in the axial direction can enhance the stirring effect on the soil, making the soil turning more even, thereby loosening the soil. Combined with the rotation of the rotary tiller 220, it can improve the stirring effect on the soil.

[0043] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that the frame 100 has multiple mounting positions arranged in the left-right direction. The positioning assembly 400 includes a fixed base 410, a connecting rod 420 and a first fastener 430. One end of the connecting rod 420 is connected to the side plate 310 and the other end is connected to the fixed base 410. The fixed base 410 can be opposite to any mounting position. Both the frame 100 and the fixed base 410 are connected to the first fastener 430.

[0044] Specifically, the left side of the frame 100 has multiple mounting positions, and two adjustment components 400 are provided. The left adjustment component 400 can be positioned opposite any mounting position on the left side of the frame 100 to move the left side plate 310 closer to or further away from the center of the shaft 210. Correspondingly, the right side of the frame 100 has multiple mounting positions, and the right adjustment component 400 can be positioned opposite any mounting position on the right side of the frame 100 to move the right side plate 310 closer to or further away from the center of the shaft 210.

[0045] Reference Figure 1 , Figure 2 and Figure 3 As shown, one end of the connecting rod 420 is connected to the side plate 310, and the other end is connected to the fixed seat 410. The fixed seat 410 can be opposite to any mounting position, that is, the mounting position of the fixed seat 410 on the frame 100 in the left and right direction can be changed. After the mounting position of the fixed seat 410 is selected, the first fastener 430 is connected to the frame 100 and the fixed seat 410, thereby fixing the relative positional relationship between the fixed seat 410 and the frame 100.

[0046] Reference Figure 1 , Figure 2 and Figure 3 As shown, the rotary tillage and ridging equipment can adjust the distance between the two side plates 310 by changing the installation position of the fixed base 410 in the left and right directions, so that the two side plates 310 are closer to or further away from the center of the shaft 210, that is, adjust the width of the ridge. The rotary tillage and ridging equipment can realize the function of adjusting the ridge shape to improve the applicability to different soil types and farmland layouts.

[0047] Reference Figure 1 , Figure 2 and Figure 3As shown, it can be understood that two connecting rods 420 are provided, and the two connecting rods 420 are arranged vertically. That is, the fixing seat 410 is connected to the side plate 310 through the two connecting rods 420. Through multi-point support, the support stability of the fixing seat 410 on the side plate 310 is enhanced, which helps to reduce the deformation of the side plate 310, so as to maintain the shape stability of the ridging channel 330 and make the formed ridge more regular.

[0048] It should be noted that more than two connecting rods 420 can be provided to improve the support stability of the fixing seat 410 for the side plate 310, so as to ensure that the ridging channel 330 maintains a stable shape.

[0049] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that, specifically, a first mounting hole 120 is provided at the mounting position, and a second mounting hole is provided on the fixing seat 410. After the first fastener 430 passes through the second mounting hole and the first mounting hole 120, the frame 100 is fixed to the fixing seat 410.

[0050] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, a first mounting hole 120 is provided at the mounting position, and a second mounting hole is provided at the fixing seat 410. When the user needs to adjust the width of the ridge, the user can change the fixing seat 410 to correspond with different mounting positions, so that the second mounting hole is opposite to multiple different first mounting holes 120. After the user adjusts the width of the ridge to a suitable width, the user can pass the first fastener 430 through the second mounting hole and the corresponding first mounting hole 120. Through the connection between the first mounting hole 120 and the second mounting hole and the first fastener 430, the relative position relationship between the fixing seat 410 and the frame 100 is fixed, which helps to avoid the problem of the fixing seat 410 coming off the frame 100.

[0051] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that the side plate 310 includes a surrounding plate 311 and a baffle 312 arranged at an angle. The surrounding plate 311 is used to form the ridging channel 330, and the baffle 312 is connected to the fixing seat 410 to close the rear end of the rotary tillage space 110.

[0052] Reference Figure 1 , Figure 2 and Figure 3As shown, the side plate 310 also serves to close the rear end of the rotary tillage space 110. Under the blocking effect of the baffle 312, the soil in the rotary tillage space 110 can be restricted from moving backward. With the spiral conveying action of the rotary tillage shaft 200, the loosened soil can be transported to the middle of the shaft 210 and pass out of the rotary tillage space 110 from the ridging channel 330. Under the shaping action of the ridging component 300, a more regular ridge is formed.

[0053] Reference Figure 1 , Figure 2 and Figure 3 As shown, the baffle 312 is connected to the fixed seat 410. When the user adjusts the relative position of the fixed seat 410 and the installation position through the adjustment component 400, the baffle 312 and the surrounding plate 311 can be moved together to adjust the width of the ridging channel 330 and thus adjust the width of the formed ridge.

[0054] It should be understood that, in some other embodiments, in order to enhance the shape stability of the retaining plate 311 and reduce the deformation amplitude of the retaining plate 311 during ridge shaping, the positioning assembly 400 further includes a support frame 440, which is connected to the surface of the retaining plate 311 facing away from the ridging channel 330. The support frame 440 includes a first sub-rod, a second sub-rod, a third sub-rod, and a fourth sub-rod. The first and second sub-rods are arranged vertically and parallel to each other. The first sub-rod is connected to the upper connecting rod 420. The two ends of the third sub-rod are respectively connected to the ends of the first sub-rod away from the baffle 312 and the ends of the second sub-rod away from the baffle 312. One end of the fourth sub-rod is connected to the junction of the second and third sub-rods, and the other end of the fourth sub-rod is connected to the baffle 312. The lower connecting rod 420 is connected to the fourth sub-rod. By setting the support frame 440, the positioning assembly 400 can enhance the support stability of the retaining plate 311, thereby reducing the deformation amplitude of the retaining plate 311 and maintaining the stability of the ridging channel 330.

[0055] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that in this embodiment, the upper edge of the upper scraper 320 is connected to a rotating shaft 510, the upper ends of the two side plates 310 are respectively connected to rotating seats, the rotating seats are provided with rotating holes 313, and the two ends of the rotating shaft 510 are respectively passed through the two rotating holes 313 and rotatably connected to the rotating holes 313.

[0056] Reference Figure 1 , Figure 2 and Figure 3 As shown, under the weight of the upper scraper 320, the upper scraper 320 tends to flip downwards, so that the upper scraper 320 can restrict the shaping of the upper part of the soil to flatten the upper part of the ridge.

[0057] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, the rotary tillage and ridging equipment also includes a compression elastic element 520. One end of the compression elastic element 520 is connected to the frame 100, and the other end is connected to the upper end face of the upper scraper 320. When the compression elastic element 520 is compressed, the compression elastic element 520 can apply a downward rotational elastic force to the upper scraper 320.

[0058] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, the compression elastic element 520 is a spring, and the upper end of the upper scraper 320 is rotatably connected to a guide rod. The guide rod is movably connected to the frame 100. The spring is sleeved on the guide rod, and its two ends abut against the frame 100 and the upper scraper 320 respectively. Under the elastic action of the spring, the upper scraper 320 is driven to rotate downward, so that the upper scraper 320 can adapt to and contact the ridge surface with different ridging heights. Under the shaping action of the upper scraper 320, the ridge surface becomes flatter. When the upper scraper 320 rotates upward, the upper scraper 320 compresses the spring, which can buffer the rotation of the upper scraper 320.

[0059] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that a cover plate 130 is rotatably connected to the upper end of the frame 100, and the cover plate 130 is used to open and close the rotary tillage space 110. That is, when the user rotates the cover plate 130 upward, the rotary tillage space 110 of the frame 100 can be opened to facilitate maintenance of the rotary tillage shaft 200 or removal of hard objects inside the rotary tillage space 110. The user can also rotate the cover downward to close the rotary tillage space 110 of the frame 100 to maintain the soil-binding effect of the rotary tillage space 110.

[0060] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
