Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and in particular to a ridging and shaping roller. Background Technology

[0002] With the increasing mechanization of agriculture, land preparation and tillage efficiency have become key factors in improving crop yields. Ridging, as an important step in soil preparation, not only affects drainage, ventilation, and light conditions for crops, but also directly relates to the efficiency of subsequent planting, irrigation, and harvesting. Traditional ridge-making operations mainly rely on various ridge-making machines, among which the ridge-shaping roller, as a core component, plays a crucial role in shaping the ridge and controlling its width and height.

[0003] However, most existing ridging and shaping rollers are fixed. For example, the ridging machine described in CN218006922U, "A Ditching and Ridging Machine," includes a mounting frame, drive unit, rotary tillage unit, ridging unit, and leveling unit. The ridging unit includes a rotating shaft, ridging components, and ridging discs. The rotating shaft is rotatably mounted on the mounting frame, while the ridging components are fixedly mounted on the shaft. This means that each shaping roller can only create ridges of a fixed width and height, limiting the flexibility and adaptability of the ridging machinery, especially when facing different crop planting needs and soil conditions. Depending on soil type or specific field management requirements, such as: sweet potatoes generally have a ridge width of 70-90cm and a ridge height of 20-30cm; potatoes generally have a ridge width of 60-80cm and a height of 0-30cm; cucumbers generally have a ridge width of 100-120cm and a height of 15-20cm; corn generally has a ridge width of 60-70cm and a height of 15-20cm; when it is necessary to adapt to different ridge shape requirements, the entire ridging and shaping roller needs to be replaced, which is complicated and time-consuming, and cannot efficiently carry out ridging operations; or another ridging machine that meets the ridge shape requirements can be used, but this will increase production costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a ridging and shaping roller, which is mainly used for ridging land, so as to achieve the purpose of adjusting the ridging width and ridging height without replacing the ridging and shaping roller, so as to adapt to the ridging shape required by different crops.

[0005] This utility model discloses a ridging and shaping roller, including a rotating shaft rotatably connected to the frame of a ridging machine and a ridging assembly disposed on the rotating shaft. The ridging assembly includes a sleeve slidably sleeved on the rotating shaft and a ridging disc in the shape of a frustum disposed on the sleeve. Two sets of oppositely arranged ridging assemblies and the rotating shaft located between the two sets of ridging assemblies are enclosed on the same horizontal plane to form a ridging cavity with a trapezoidal cross section. The ridging disc includes a ridging section and a frustum section. The ridging section is disposed on the side of the sleeve away from the end of the rotating shaft. The frustum section is slidably disposed on the sleeve and detachably connected to the ridging section. A locking mechanism for fixing the sleeve is provided on the side of the sleeve near the end of the rotating shaft.

[0006] Furthermore, at least two of the said frustum segments are slidably disposed on the sleeve, and adjacent frustum segments are detachably connected.

[0007] As a preferred embodiment, the ridging section is fixedly provided with a threaded rod that passes through the frustum section and extends toward the end of the rotating shaft, and the end of the threaded rod away from the ridging section is threadedly connected to a locking nut for pressing the frustum section.

[0008] As a preferred embodiment, the threaded rod is also provided with a back-tightening nut.

[0009] Furthermore, the locking mechanism includes a pipe clamp, and at least two slits are spaced apart circumferentially at one end of the sleeve away from the ridging section. The pipe clamp includes a clamp body and connecting parts disposed at both ends of the clamp body. The clamp body passes through the slits in sequence and is arranged around the pivot. The connecting parts are located on the outside of the sleeve, and a fixing bolt for locking the clamp body is threaded onto the connecting parts.

[0010] As a preferred embodiment, the locking mechanism further includes a tightening bolt, the tightening bolt being threaded at the end of the sleeve away from the ridging section, and one end of the tightening bolt penetrating the sleeve and abutting against the rotating shaft.

[0011] The beneficial effects of this utility model are as follows: The ridging assembly of the ridging and shaping roller includes a sleeve and a detachably connected ridging disc. The distance between the two ridging sections can be adjusted by sliding the sleeve to adjust the ridging width. The ridging height can be adjusted by adjusting the number of frustum sections or changing the size of the frustum sections. Using this ridging and shaping roller for ridging operations can quickly adjust the ridging width and height to adapt to the ridging shape required by different crops, improve the efficiency of ridging operations, and the adjustment method is simple and easy for operators to operate.

Detailed Implementation

[0016] The present invention will be further described below.

[0017] This utility model provides a ridging and shaping roller, mainly used for ridging land. It includes a rotating shaft 2 rotatably connected to the frame 1 of a ridging machine and ridging components 3 disposed on the rotating shaft 2. Two sets of ridging components 3 are disposed opposite to each other at both ends of the rotating shaft 2, and the two sets of ridging components 3 and the rotating shaft 2 are enclosed on the same horizontal plane to form a ridging cavity with a trapezoidal cross section. The ridging component 3 includes a sleeve 31 slidably sleeved on the rotating shaft 2 and a ridging disc 32 in the shape of a frustum disposed on the sleeve 31. The ridging disc 32 includes a ridging section 321 and a frustum section 322. The ridging section 321 is disposed on the side of the sleeve 31 away from the end of the rotating shaft 2. The frustum section 322 is slidably disposed on the sleeve 31 and detachably connected to the ridging section 321. A locking mechanism 33 for fixing the sleeve 31 is provided on the side of the sleeve 31 near the end of the rotating shaft 2.

[0018] like Figures 1-3As shown, the ridging and shaping roller includes a rotating shaft 2 and ridging components 3. The rotating shaft 2 is rotatably mounted on the frame 1 of the ridging machine and is driven to rotate by the drive mechanism 11, thereby driving the rotation of the entire ridging and shaping roller. Two sets of ridging components 3 are arranged opposite to each other at both ends of the rotating shaft 2, and the cross-section formed by the two sets of ridging components 3 and the rotating shaft 2 on the same horizontal plane is a trapezoidal ridging cavity that is narrow at the top and wide at the bottom. When the ridging machine digs and rids in the land, the ridging components 3 press down the soil on both sides to achieve ridging. The sleeve 31 is slidably fitted onto the rotating shaft 2, allowing it to move axially along the shaft 2. The ridging disc 32 is frustum-shaped, comprising a ridging section 321 and a frustum-shaped section 322. The ridging section 321 is located on the side of the sleeve 31 away from the end of the rotating shaft 2, and is used to form the top of the ridge. The width of the ridge is determined relative to the ridging sections 321 located at both ends of the rotating shaft 2. Therefore, when it is necessary to adjust the width of the ridge formed by the ridging and shaping roller, it is only necessary to slide the sleeve 31, thereby driving the movement of the ridging section 321, and adjusting the width of the ridging sections 321 located at both ends of the rotating shaft 2. The spacing between the sleeves allows for adjustment of the ridge width. After adjustment, the sleeve 31 is fixed using a locking mechanism 33 located on the side away from the ridging section 321 to prevent it from sliding along the axis of the rotating shaft 2, thus fixing the ridge width. The frustum section 322 is slidably mounted on the sleeve 31 and detachably connected to the ridging section 321. Different sizes of frustum sections 322 can be installed behind the ridging section 321 to control the ridge height. However, it is important to ensure that the connection between the frustum section 322 and the ridging section 321 is level. A smooth transition is used to ensure the integrity of the ridge shape; the frustum section 322 and the ridging section 321 can be connected by detachable methods such as bolts, tenons, or clips, so that the size of the frustum section 322 can be selected according to the required ridging height, thereby achieving the purpose of adjusting the ridge height; the locking mechanism 33 can use bolts, rope binding, or clips to fix the sleeve 31 to the rotating shaft 2 to prevent it from sliding during use and affecting the width of the ridge; the ridging and shaping roller adjusts the distance between the two ridging sections 321 by sliding the sleeve 31, thus achieving... The ridge width can be adjusted by changing the number of frustum sections 322 or by changing the size of the frustum sections 322, thereby adjusting the ridge height. The position of the sleeve 31 is fixed by the locking mechanism 33 set on the sleeve 31 to ensure the stability of the ridge shaping roller. Using this ridge shaping roller for ridge operation can quickly adjust the ridge width and ridge height to adapt to the ridge shape required by different crops, improving the efficiency and safety of ridge operation. Moreover, the adjustment method is simple and easy for operators to quickly adjust and install, reducing the labor intensity of operators.

[0019] As a preferred method, such as Figure 3 As shown, multiple ridging and shaping rollers can be installed on the frame 1 of the ridging machine to perform multiple ridging operations simultaneously, thereby improving the efficiency of the ridging operation. For details, please refer to the installation and connection method described in CN218006922U "A Ditching and Ridging Machine".

[0020] When using the ridging and shaping roller, first install the roller on the ridging machine frame 1, and select the appropriate ridging section 321 and frustum section 322 according to the type of crop and soil conditions. Adjust the position of the sleeve 31 on the rotating shaft 2 to form the required ridging cavity. Next, fix the position of the sleeve 31 by the locking mechanism 33 to ensure the stability of the ridging and shaping roller. Finally, start the power unit on the ridging machine frame 1 to drive the rotating shaft 2 to rotate, thereby realizing the ridging operation.

[0021] To reduce the weight of the frustum section 322, so that operators can adjust the ridge height of the ridging and shaping roller, such as... Figure 1 As shown, at least two frustum sections 322 are slidably disposed on the sleeve 31, and adjacent frustum sections 322 are detachably connected; the detachable connection between the frustum sections 322 can be made by bolts, tenons or buckles, etc.; the ridge height can be adjusted by increasing or decreasing the number of frustum sections 322, and increasing the number of frustum sections 322 can reduce the weight of each frustum section 322, making it easier for operators to disassemble and assemble; the width of the frustum section 322 is preferably 5cm, which can form a smooth transition with the ridging section 321, and at the same time facilitate the gradual adjustment of the ridge height according to planting needs.

[0022] To facilitate the disassembly and installation of the frustum section 322, enable rapid adjustment of ridge height, and ensure that the frustum section 322 remains in close contact with the ridging section 321 during use, thus guaranteeing the integrity of the ridge shape, such as... Figure 1 , Figure 2 As shown, a threaded rod 3211 is fixedly provided on the ridging section 321, which passes through the frustum section 322 and extends toward the end of the rotating shaft 2. A locking nut 3212 for pressing the frustum section 322 is threadedly connected to the end of the threaded rod 3211 away from the ridging section 321. By fixing the threaded rod 3211 on the ridging section 321 and opening a through hole at the frustum end for the threaded rod 3211 to pass through, the frustum section 322 can be inserted onto the threaded rod 3211. A locking nut 3212 is provided at the end of the threaded rod 3211 away from the ridging section 321. By tightening the locking nut 3212, the frustum section 322, which passes through the threaded rod 3211, is locked and fixed, enabling rapid adjustment of the ridge height and ensuring that the frustum section 322 remains in close contact with the ridge section 321 during use. Since the threaded rod 3211 is located within the ridge section 321, it does not affect the ridge shape when rotating with the shaft 2 for ridge formation. To ensure that the frustum section 322 does not shift vertically after passing through the threaded rod 3211, affecting its transition connection and fit with the ridge section 321, as follows... Figure 1 , Figure 2As shown, at least two threaded rods 3211 are symmetrically arranged to connect and install the frustum section 322. To further tighten the frustum section 322 and the ridging section 321, and to prevent gaps from forming between the frustum section 322 and the ridging section 321, which would affect the integrity of the ridging, as shown... Figure 1 , Figure 2 As shown, the threaded rod 3211 is also provided with a back tightening nut 3213. By adding the back tightening nut 3213, the frustum section 322 and the ridging section 321 are further locked. At the same time, it effectively prevents the locking nut 3212 from slipping off the threaded rod 3211 due to vibration during the use of the ridging and shaping roller, and further ensures the stability of the ridging assembly 3 during use.

[0023] To ensure the stability of the fixation between the sleeve 31 and the rotating shaft 2, and to prevent the locking mechanism 33 from failing to fix the sleeve 31 due to the rotation and vibration of the rotating shaft 2 during the use of the ridging and shaping roller, thus avoiding slippage of the sleeve 31 during ridging and affecting the width of the ridged land, such as... Figure 2 As shown, the locking mechanism 33 includes a pipe clamp 331. At least two slits 311 are spaced circumferentially at the end of the sleeve 31 away from the ridging section 321. The pipe clamp 331 includes a clamp body 3311 and connecting portions 3312 at both ends of the clamp body 3311. The clamp body 3311 passes through the slits 311 sequentially and surrounds the rotating shaft 2. The connecting portions 3312 are located outside the sleeve 31, and fixing bolts 332 for locking the clamp body 3311 are threaded onto the connecting portions 3312. Multiple slits 311 are provided at the end of the sleeve 31 away from the ridging section 321. The width of each slit 311 is the same as the size of the clamp body 3311, allowing the clamp body 3311 to pass through. Figure 2 As shown, the hoop 3311 is mounted on the sleeve 31 and passes through the gap 311 to extend into the sleeve 31 and surround the rotating shaft 2. The connecting portions 3312 at both ends of the hoop 3311 are located on the outside of the sleeve 31 and are locked by fixing bolts 332 threaded on the connecting portions 3312. Specifically, the rod 3321 of the fixing bolt 332 passes through the connecting portion 3312, and a fixing nut 3322 is threaded onto the rod 3321. By tightening the fixing nut 3322, the hoop 3311 wrapped around the rotating shaft 2 is locked. 1. The sleeve 31 is installed on the sleeve 31. Therefore, when the hoop 3311 is locked on the rotating shaft 2, the sleeve 31 will also be locked with the rotating shaft 2, realizing bidirectional locking and ensuring that the sleeve 31 cannot move, so as to fix the position of the ridging section 321, that is, fix the ridge width. When it is necessary to slide the sleeve 31 to adjust the position of the ridging section 321 to adjust the ridge width, simply loosen the fixing nut 3322 so that the hoop 3311 and the rotating shaft 2 are no longer tightly attached, and the sleeve 31 can be slid to adjust the ridge width. The hoop 331 is set at the end of the sleeve 31 away from the ridging section 321 so as to set the frustum section 322 to adjust the ridge height.

[0024] To further fix the position of sleeve 31 on the rotating shaft 2, such as Figure 2 As shown, the locking mechanism 33 also includes a tightening bolt 333, which is threaded at the end of the sleeve 31 away from the ridging section 321. One end of the tightening bolt 333 passes through the sleeve 31 and abuts against the rotating shaft 2. The tightening bolt 333 is provided at the end of the sleeve 31 away from the ridging section 321. By screwing the tightening bolt 333, the end of the tightening bolt 333 facing the rotating shaft 2 is tightened against the rotating shaft 2. Specifically, multiple tightening bolts 333 are arranged on the sleeve 31 along the circumference of the sleeve 31 to strengthen the fixation of the sleeve 31.

[0025] Based on the requirements of ridge cultivation for crops and soil conditions, the angle between the ridge plane and the ridge side is usually 120°. Therefore, if... Figure 1 As shown, the included angle between the ridging disc 32 and the rotating shaft 2 is 120°, so that the included angle between the ridge plane formed by the ridging and shaping roller and the side of the ridge is 120°.

[0026] To avoid the ridge height adjustment being too large or too small when adjusting the ridge height by adding or removing the truncated cone section 322 due to the width being too large or too small, thus making it impossible to quickly complete the ridge height adjustment, the width of the ridge section 321 is 10cm, and the width of the truncated cone section 322 is 5cm.
