Description

Technical Field

[0001] This invention relates to the field of crop planting technology, specifically to an integrated machine for tilling, hilling, and weeding crops. Background Technology

[0002] For crops such as potatoes, sweet potatoes, and peanuts, hilling can promote better root growth. Better root growth leads to higher yields. Furthermore, repeated hilling creates a soil-gathering effect around the crop plants, drawing nutrients and water away from the plant roots for better utilization. This increases fertilizer efficiency. Simultaneously, the absence of chemical fertilizer residue improves soil quality, allowing crops to absorb sufficient water and nutrients, naturally increasing yields. Hilling also increases the space for root growth; the higher the mound, the more space the roots have to grow, resulting in larger fruits due to ample nutrient and water supply. Therefore, hilling helps increase soil water retention and fertility, improving crop yield and quality.

[0003] In the process of crop production, it may be necessary to use a cultivator to perform multiple hilling and weeding operations. However, the cultivators in general technology cannot make it convenient for users to adjust the soil depth according to actual needs. Moreover, existing cultivators lack auxiliary mechanisms, their hilling and weeding range is limited, they cannot effectively transport the tilled soil to the crops on both sides, and they may not be able to remove weeds at the edges between rows. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated machine for tilling, hilling, and weeding crops, which aims to solve the problem that the tilling and weeding effects of general tillers for crops are not good enough.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The integrated machine for tilling, ridging, and weeding crops includes: a mounting frame, a tiller, and a side plate. The mounting frame is used to connect to the vehicle body. The tiller is detachably mounted on the mounting frame. The tiller includes a mounting part for connecting to the mounting frame. An adjusting part is rotatably mounted on the bottom of the mounting part. Adjusting rods for limiting the movement of both the mounting part and the adjusting part are inserted inside. The adjusting rods are fixedly connected to the mounting frame. A plowshare for tilling is detachably mounted on the bottom of the adjusting part via a first sliding rod. Rotating the adjusting part... The angle of the plowshare is adjusted to adjust its tillage depth. Adjusting the length of the first sliding rod connected to the adjusting part can further adjust the tillage depth. Side plates are detachably installed on both sides of the adjusting part via the second sliding rod. The side plates have an arc-shaped structure, and the bottom of the side plates has blades for weeding. The arc-shaped convex surface of the side plates faces forward to guide and assist in hilling. The side plates are installed in reverse so that the arc-shaped concave surface faces forward so that the blades can weed the edges that the plowshare cannot reach between rows. The width of the side plates is adjusted by adjusting the length of the second sliding rod connected to the adjusting part.

[0006] The beneficial effects are as follows: The installation of the plowshare via an adjustable section that is rotatably connected to the mounting section not only allows the user to easily adjust the tillage depth of the plowshare by rotating the angle of the adjustable section, but also allows the first sliding rod of the plowshare to slide within the adjustable section as needed, thereby further fine-tuning the tillage depth. Furthermore, the side plate installed in the middle of the adjustable section not only allows for guiding and assisting in hilling during inter-row cultivation by the forward-mounted side plate, but also allows for weeding at edges that the plowshare cannot reach through the blades by installing the side plate in the reverse direction. The position of the side plate can also be adjusted according to the crop row spacing, thereby adjusting the weeding and hilling positions.

[0007] A further technical solution of the present invention is that the mounting part includes a first connecting plate, a first clamping plate is fixedly mounted on the top of the first connecting plate, and a second clamping plate is mounted on the four corners of the first clamping plate by a first mounting bolt. The second clamping plate and the first clamping plate are respectively located on the upper and lower sides of the mounting frame, and a first mounting nut is threaded onto the bottom end of the first mounting bolt.

[0008] A further technical solution of the present invention is that a first adjustment hole is provided inside the bottom end of the first connecting plate, the first adjustment hole is used to install the adjustment rod, and a set of arc-shaped blocks are fixedly installed on both sides of the bottom end of the first connecting plate. The number of arc-shaped blocks in each set is two, and the two arc-shaped blocks in each set are arranged in a circular array with the first adjustment hole as the center. A stop block is fixedly installed at the end of each arc-shaped block.

[0009] A further technical solution of the present invention is that the adjusting part includes a second connecting plate, and adjusting plates are fixedly installed on both sides of the top of the second connecting plate. The interior of each of the two adjusting plates is provided with a second adjusting hole corresponding to the first adjusting hole. The interior of each adjusting plate is provided with a set of adjusting grooves, and the number of adjusting grooves in each set is two. The two adjusting grooves in each set are circumferentially distributed with the second adjusting hole as the center. The two arc-shaped blocks in each set are slidably installed in the interior of the two adjusting grooves in each set, and the arc-shaped blocks can be rotated from one end of the adjusting groove to the other end, so that the adjusting part can be rotated relative to the mounting part to adjust its angle. The adjusting rod is simultaneously inserted into the interior of the first adjusting hole and the second adjusting hole to fix and limit the adjusting part after the angle is adjusted.

[0010] A further technical solution of the present invention is that a first mounting sleeve for installing a plow blade is fixedly installed at the bottom of the second connecting plate, and a second mounting bolt for limiting the plow blade is installed in the internal thread of the first mounting sleeve. A second mounting sleeve for installing a side plate is fixedly installed at the upper middle position on both sides of the second connecting plate, and a third mounting bolt for fixing the side plate is installed in the internal thread of the second mounting sleeve.

[0011] The beneficial effects are: it makes it easier for users to install the plowshare and side plates, and it also makes it easier for users to adjust the position of the plowshare and side plates according to actual needs.

[0012] A further technical solution of the present invention is that the plow includes a first sliding rod, one end of which is slidably installed inside the first mounting sleeve. The first sliding rod has a plurality of first positioning holes for installing the second mounting bolts. The other end of the first sliding rod is fixedly installed with a shovel head. A baffle is fixedly installed on the upper surface of the shovel head near the end of the first sliding rod. The presence of the baffle can prevent the soil scooped up by the shovel head from being directly swept away through the upper surface of the shovel head and affecting the backfilling of the side plate.

[0013] A further technical solution of the present invention is that a second slide rod is fixedly installed on the inner wall of the side plate, the other end of the second slide rod is inserted into the interior of the second mounting sleeve, and a plurality of second positioning holes for installing the third mounting bolt are provided inside the second slide rod.

[0014] A further technical solution of the present invention is that the adjusting rod includes multiple adjusting sections and rotating sections, which are staggered. The adjusting sections are prism-shaped with a polygonal cross-section that is the same shape as the mounting hole. The rotating sections are cylindrical with a diameter smaller than the diameter of the inscribed circle of the adjusting section. The adjusting sections are simultaneously inserted into the interior of the first mounting plate, the second mounting plate, the first adjusting hole, and the second adjusting hole to limit the adjustment part. Moving the adjusting rod to allow the rotating sections to enter the interior of the first mounting plate, the second mounting plate, the first adjusting hole, and the second adjusting hole allows the adjustment part to be rotated to adjust the angle.

[0015] A further technical solution of the present invention is that a fixing plate is rotatably mounted on one end of the adjusting rod, and a fixing bolt for connecting the first mounting plate is installed on the internal thread of the fixing plate.

[0016] The beneficial effect is that it allows users to easily fix the adjustment part, and only requires loosening the fixing bolts and pulling the adjustment rod a certain distance to allow users to adjust the angle of the rotating part.

[0017] A further technical solution of the present invention is that multiple reinforcing plates are fixedly installed at both the front and rear ends of the bottom of the mounting frame, and connecting blocks are installed inside the reinforcing plates through connecting bearings. A first mounting hole is opened inside the connecting blocks. A first mounting plate and a second mounting plate are respectively installed at the left and right ends of the mounting frame. A second mounting hole and a third mounting hole are respectively opened inside the first mounting plate and the second mounting plate. The first mounting hole, the second mounting hole and the third mounting hole are all used to limit the installation of the adjusting rod. Attached Figure Description

Detailed Implementation

[0032] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0033] Example 1: In general technology, tillers cannot be easily adjusted by users according to actual needs, nor can they be easily disassembled and maintained by users.

[0034] Based on the above problems, this implementation example Figures 1-2 As shown, a combined tillage, hilling, and weeding machine for crops includes a mounting frame 1. A first tiller 2 and a second tiller 3 are detachably mounted at the front and rear ends of the mounting frame 1, respectively. The first tiller 2 and the second tiller 3 are spaced apart. A first mounting plate 11 and a second mounting plate 12 are fixedly mounted at the left and right ends of the bottom of the mounting frame 1, respectively. Adjusting rods 4, which are polygonal prisms, are installed inside the first mounting plates 11 and 12 for adjusting the angle of the first tiller 2 and the second tiller 3. The rod 4 is inserted into the interior of the first tillage plow 2 and the second tillage plow 3. Rotating the adjusting rod 4 causes the first tillage plow 2 and the second tillage plow 3 to rotate accordingly to adjust the angle, thereby adjusting the tillage depth of the first tillage plow 2 and the second tillage plow 3. Both the first tillage plow 2 and the second tillage plow 3 can be detachably equipped with side plates 24. The side plates 24 are used to assist in hilling when installed upright and to assist in weeding when installed in reverse. The first tillage plow 2 and the second tillage plow 3 can be used to deeply dig between crop rows to hill up the crops, or to shallowly dig between crop rows to weed.

[0035] like Figures 7-8 As shown, the mounting frame 1 is a rectangular frame structure. Multiple reinforcing rods 101 are fixedly installed inside the mounting frame 1. Multiple first fixing plates 102 are fixedly installed at the front end of the mounting frame 1. Second fixing plates 103 are fixedly installed on the upper surface of each of the reinforcing rods 101. First connecting rods 13 are rotatably mounted on two of the first fixing plates 102. Multiple connecting holes 131 are opened at the other end of the first connecting rods 13. Two opposing connecting holes 131 inside the two first connecting rods 13 are used to connect to the vehicle body to facilitate the overall movement of the device. A second connecting rod 14 is rotatably mounted on the second fixing plate 103. The second connecting rod 14 is rotatably mounted inside the connecting hole 131 via the connecting shaft 15. The second connecting rod 14 is used to reinforce the first connecting rod 13, so that the first connecting rod 13, the second connecting rod 14 and the mounting bracket 1 form a relatively stable triangular structure. It can be imagined that, as the inclination of the first connecting rod 13 is different, and the length of the second connecting rod 14 is constant, the second connecting rod 14 needs to be rotatably mounted inside different connecting holes 131 via the connecting shaft 15.

[0036] Multiple reinforcing plates 16 are fixedly installed at both the front and rear ends of the bottom of the mounting bracket 1. Connecting blocks 17 are installed inside the reinforcing plates 16 via connecting bearings 161. A first mounting hole 171 is opened inside the connecting block 17. A second mounting hole 111 and a third mounting hole 121 are opened inside the first mounting plate 11 and the second mounting plate 12, respectively. The positions of the first mounting hole 171, the second mounting hole 111 and the third mounting hole 121 correspond to each other. The cross-sections of the first mounting hole 171, the second mounting hole 111 and the third mounting hole 121 are all polygonal. The adjusting rod 4 can be slidably installed inside the connecting block 17, the first mounting plate 11 and the second mounting plate 12. Multiple fixing holes 112 are opened inside the first mounting plate 11. The multiple fixing holes 112 are evenly distributed around the second mounting hole 111.

[0037] like Figures 3-6 and Figures 9-11 As shown, the second tillage plow 2 includes an installation part 21, which is fixedly installed on the mounting frame 1. An adjustment part 22 is rotatably installed at the bottom of the installation part 21. A plow shovel 23 is installed at the bottom of the adjustment part 22. Side plates 24 are slidably installed on both sides of the adjustment part 22. The side plates 24 have an arc-shaped structure, and the bottom of the side plates 24 is provided with blades for weeding.

[0038] During cultivation, the tilt angle of the adjustment unit 22 is adjusted so that the plow shovel 23 can penetrate deep into the soil between the crop rows to scoop up the soil. At this time, the arc-shaped surface of the side plate 24 faces forward and guides the soil scooped up by the plow shovel 23 to the crops on both sides. During weeding, the tilt angle of the adjustment unit 22 is adjusted again so that the plow shovel 23 penetrates less into the soil between the crop rows to remove weeds. At this time, the side plate 24 is installed in the opposite direction and tilted slightly forward so that the blade of the side plate 24 can remove weeds in areas that the plow shovel 23 cannot reach between the rows.

[0039] The mounting part 21 includes a first connecting plate 211. A first clamping plate 212 is fixedly mounted on the top of the first connecting plate 211. A second clamping plate 215 is mounted at the four corners of the first clamping plate 212 by a first mounting bolt 213. The second clamping plate 215 and the first clamping plate 212 are located on the upper and lower sides of the mounting frame 1, respectively. A first mounting nut 214 is threaded onto the bottom end of the first mounting bolt 213. The first mounting nut 214 abuts against the lower surface of the first clamping plate 212, which facilitates the user's disassembly and maintenance of the tiller. A first adjustment hole 215 is opened inside the bottom end of the first connecting plate 211. The first adjustment hole 215 is exactly the same in shape and size as the first mounting hole 171. A set of arc-shaped blocks 216 is fixedly mounted on both sides of the bottom end of the first connecting plate 211. There are two arc-shaped blocks 216 in each set. The two arc-shaped blocks 216 in each set are arranged in a circular array with the first adjustment hole 215 as the center. A stop block 217 is fixedly mounted on the end of each arc-shaped block 216.

[0040] The adjusting part 22 includes a second connecting plate 221. Adjusting plates 222 are fixedly installed on both sides of the top of the second connecting plate 221. Each adjusting plate 222 has a second adjusting hole 223 corresponding to the first adjusting hole 215. Each adjusting plate 222 has a set of two adjusting grooves 224. The two adjusting grooves 224 in each set are circumferentially distributed around the second adjusting hole 223. Two arc-shaped blocks 216 in each set are slidably installed inside the two adjusting grooves 224 in each set. The arc-shaped blocks 216 can rotate from one end of the adjusting groove 224 to the other end, thereby allowing the adjusting part 22 to be positioned relative to the mounting part 21. The angle is adjusted by rotating the adjustment rod 4, which is simultaneously inserted into the first adjustment hole 215 and the second adjustment hole 223 to fix and limit the adjustment part 22 after the angle is adjusted. The bottom of the second connecting plate 221 is fixedly installed with a first mounting sleeve 225 for installing the plow shovel 23. The internal thread of the first mounting sleeve 225 is installed with a second mounting bolt 226 for limiting the plow shovel 23. The upper middle part of both sides of the second connecting plate 221 is fixedly installed with a second mounting sleeve 227 for installing the side plate 24. The internal thread of the second mounting sleeve 227 is installed with a third mounting bolt 228 for fixing the side plate 24.

[0041] The plow shovel 23 includes a first sliding rod 231. One end of the first sliding rod 231 is slidably installed inside the first mounting sleeve 225. The first sliding rod 231 has multiple first positioning holes 232 for installing the second mounting bolt 226. The other end of the first sliding rod 231 is fixedly installed with a shovel head 233. A baffle 234 is fixedly installed on the upper surface of the shovel head 233 near the end of the first sliding rod 231. The presence of the baffle 234 can prevent the soil scooped up by the shovel head 233 from being directly scraped away through the upper surface of the shovel head 233 and affecting the soil covering of the side plate 24. The second mounting bolt 226 is installed inside one of the positioning holes 232, which makes it convenient for the user to adjust the length of the shovel head 233 extending out of the first mounting sleeve 225, and thus adjust the depth of the shovel head 233 penetrating the soil.

[0042] A second sliding rod 241 is fixedly installed on the inner wall of the side plate 24. The other end of the second sliding rod 241 is inserted into the inside of the second mounting sleeve 227. The inside of the second sliding rod 241 is provided with a plurality of second positioning holes 242 for installing the third mounting bolt 228. The user can adjust the length of the second sliding rod 241 in the second mounting sleeve 227 according to the crop row spacing, thereby adjusting the position of the side plate 24 to achieve better soil covering and weeding effects. When the side plate 24 is reversed, the positions of the two side plates 24 are interchanged.

[0043] The second tillage plow 3 has the same structure as the first tillage plow 2. The difference in name between the first tillage plow 2 and the second tillage plow 3 is to facilitate the distinction between the different positions of the tillage plows.

[0044] like Figure 12 As shown, the adjusting rod 4 includes multiple adjusting sections 41 and rotating sections 42, which are staggered. The adjusting sections 41 are prism-shaped with a polygonal cross-section that matches the shape of the mounting hole. The rotating sections 42 are cylindrical with a diameter smaller than the diameter of the inscribed circle of the adjusting section 41. A fixing plate 43 is rotatably mounted on one end of the adjusting rod 4. A fixing bolt 44 is threaded inside the fixing plate 43 and installed inside the fixing hole 112. When the fixing bolt 44 is installed inside the fixing hole 112, the multiple adjusting sections 41 are respectively inserted into the first mounting hole 171, the second mounting hole 111, and the third mounting hole 121, thereby installing the adjusting rod 4 as a whole. At this time, the multiple adjusting sections 41 are respectively inserted into the mounting part 21 and the adjusting part 22, thereby fixing the tilt angle of the adjusting part 22.

[0045] When the rotating part 22 needs to be adjusted, the adjusting rod 4 can be pulled from one end of the fixing plate 43 to allow the rotating section 42 to enter the mounting part 21 and the adjusting part 22, while retaining a portion of the adjusting section 41 inside one adjusting plate 222 of the adjusting part 22. This makes it convenient for the user to adjust the angle of the rotating part 22 by rotating the adjusting rod 4. After the rotating part 22 is adjusted, the adjusting rod 4 is reset and re-fixed. To facilitate the rotation of the adjusting rod 4, a handle 45 can be provided at one end of the fixing plate 43 of the adjusting rod 4.

[0046] In this specific embodiment, by setting an adjustment part 22 rotatably connected to the mounting part 21, and setting a first mounting sleeve 225 at the bottom of the adjustment part 22 to install the plow shovel 23, it is not only convenient for the user to adjust the soil depth of the plow shovel 23 by rotating the angle of the adjustment part 22, but also the first sliding rod 231 of the plow shovel 23 can be slid in the first mounting sleeve 225 as needed, thereby further fine-tuning the soil depth of the plow shovel 23; and a second mounting sleeve 227 is set in the middle of the adjustment part 22 to install the side plate 24. It can not only assist in hilling by installing the side plate 24 in the forward direction during inter-cultivation, but also adjust the position of the side plate 24 according to the size of the crop row spacing, and can also install the side plate 24 in the reverse direction to assist in weeding. The mounting part 21, the plow shovel 23 and the side plate 24 are all connected and fixed by bolts, which is convenient for the user to disassemble and maintain.

[0047] In Example 2, in the structure of Example 1, the second mounting sleeve 227 and the second sliding rod 241 are positioned relatively low. During the weeding process, the second sleeve 227 and the second sliding rod 241 may block the weeds removed by the plow shovel 23 and the side plate 24, causing the weeds to become entangled and blockage, affecting the weeding effect of the plow shovel 23 and the side plate 24.

[0048] Based on the above problems, this example Figure 13 As shown, the second mounting sleeve 227 is mounted on the adjusting plate 222, and a plurality of connecting strips 243 for mounting the second slide rod 241 are fixedly installed on the inner wall of the side plate 24.

[0049] Compared to Embodiment 1, this embodiment raises the height of the second slide bar 241 and the height of the second mounting sleeve 227 by using the connecting strip 243, so as to minimize the blockage of weeds.

[0050] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. The basic concept of the present invention is to connect the mounting part 21 with the mounting frame 1, which facilitates the user to adjust the position of the first tillage plow 2 and the second tillage plow 3 and to perform subsequent maintenance. An adjustment part 22 with a rotatable connection is provided at the bottom of the mounting part 21, and a first mounting sleeve 225 is provided at the bottom of the adjustment part 22 to install the plow shovel 23, thereby realizing multiple adjustments to the tillage depth of the tillage plow. Side plates 24 are provided on both sides of the adjustment part 22 to assist in hilling and weeding, making it convenient for the user to use. Furthermore, the mounting part 21, the plow shovel 23, and the side plates 24 are all detachably connected, allowing for easy disassembly and maintenance by the user. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
