Description

Technical Field

[0001] The utility model relates to the technical field of farmland ditching, in particular to a farmland water conservancy ditching device. Background Technique

[0002] Farmland water conservancy refers to water conservancy engineering measures aimed at increasing agricultural production. When planting different crops, different crops have different requirements for water sources and soil fertilizers. For example, in the field planting of potatoes, beans, and vegetables, ridge-making operations are often carried out after plowing to improve the adaptability of crops, so it is necessary to use a ditching device to dig ditches in the fields.

[0003] For example, a farmland ditching device for farmland water utilization with the application number CN202321966707.9 includes a mounting plate. One side of the top surface of the mounting plate is fixed with a driving motor, and the driving end of the driving motor is fixed with a driving sprocket and a sector gear. Both sides of the front end of the mounting plate are fixed with mounting parts, and a connecting rod is rotatably connected between the mounting parts. A brush is arranged on the outer wall of the connecting rod. One end of the connecting rod is fixed with a driven sprocket. A chain is meshed and connected on the outer sides of the driving sprocket and the driven sprocket. Both ends of the bottom side of the mounting plate are fixed with fixing parts, and a mounting rod is rotatably connected between the fixing parts. Through the mutual cooperation of the driving motor, driving sprocket, chain, driven sprocket, connecting rod, and brush, the utility model can clean the soil on the surface of the ditching knife, thereby improving the grooving efficiency.

[0004] When the farmland ditching device proposed in the above patent uses the ditching knife at the lower end of the ditching device to dig ditches in the farmland, the ditching knife is prone to adhesion of soil, etc. The driving motor drives the driving sprocket, chain, driven sprocket, connecting rod, and brush to rotate, so that the brush cleans the soil on the outer surface of the ditching knife. Since the brush is in a rolling state during the cleaning process and there is no shield at the upper end of the brush, such a setting results in that when the brush cleans the ditching knife, the brush will drive the soil to splash.

[0005] Therefore, we propose a farmland water conservancy ditching device to solve the above-mentioned problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a farmland water conservancy ditching device to solve the problem that when the brush cleans the ditching knife, the brush will drive the soil to splash because the brush is in a rolling state during the cleaning process and there is no shield at the upper end of the brush as mentioned in the above background technique.

[0007] To achieve the above object, the present utility model provides the following technical solution: A farmland water conservancy ditching device, comprising a ditching assembly and a control handle fixedly installed at the upper end of the ditching assembly. A driving assembly is arranged on one side of the upper end of the ditching assembly. One end of the driving assembly is connected to a sprocket assembly. One end of the sprocket assembly is installed with a brush through a connecting rod. One side of the outer wall of the ditching assembly is fixedly installed with a shielding assembly adapted to protect the upper end of the brush;

[0008] The shielding assembly includes a support mechanism and an extension mechanism movably installed at one end of the support mechanism. Both sides of the upper end of the extension mechanism are threadedly connected with a fixing mechanism, and the extension mechanism is fixedly installed in the inner cavity of the support mechanism through the fixing mechanism.

[0009] Preferably, the support mechanism includes an upper right-angle plate and through grooves opened on both sides of the upper end of the upper right-angle plate. A plurality of threaded grooves are linearly and equidistantly opened on one side of the outer surface of the upper right-angle plate at the upper end.

[0010] Preferably, a fitting groove is opened in the middle of one end of the upper right-angle plate, and concave grooves are opened on both sides of the inner wall of the fitting groove.

[0011] Preferably, the extension mechanism includes a lower right-angle plate and a U-shaped connecting rod fixedly installed on one side of the upper end of the lower right-angle plate.

[0012] Preferably, mounting threads are embedded in the lower end of the outer surface of the U-shaped connecting rod, and protruding blocks are respectively fixedly installed at both ends of the outer wall of the lower right-angle plate.

[0013] Preferably, the fixing mechanism includes a round nut and arc-shaped rods fixedly installed at both ends of the outer wall of the round nut. A ring is fixedly installed at the upper end of the arc-shaped rod.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. When the brush cleans the ditching knife and the soil carried out by the brush splashes, it will be directly blocked by the upper right-angle plate and the lower right-angle plate fixedly installed at one end of the outer wall of the ditching assembly, thereby reducing the splashing of soil everywhere.

[0016] 2. When the operator adjusts the position of one end of the lower right-angle plate in the inner cavity of the upper right-angle plate, directly pull the lower right-angle plate to make it slide in the inner cavity of the fitting groove, and drive the arc-shaped rod and the round nut to rotate by rotating the ring, so that the round nut tightly presses the lower right-angle plate threadedly at the upper end of the notch of the through groove for fixation, thereby completing the position adjustment and fixation of the lower right-angle plate.

[0024] The shielding assembly 6 includes a support mechanism 61 and an extension mechanism 62 movably installed at one end of the support mechanism 61. The upper end of the extension mechanism 62 is threadedly connected with a fixing mechanism 63 on both sides, and the extension mechanism 62 is fixedly installed in the inner cavity of the support mechanism 61 through the fixing mechanism 63.

[0025] The support mechanism 61 includes an upper right-angle plate 611 and through grooves 612 opened on both sides of the upper end of the upper right-angle plate 611. A plurality of threaded grooves 613 are linearly and equidistantly opened on one side of the outer surface of the upper right-angle plate 611 at the upper end. The upper right-angle plate 611 is threadedly fixed and installed on one side of the upper end of the outer wall of the ditch-opening assembly 1 through the threaded grooves 613 by screws.

[0026] A middle part of one end of the upper right-angled plate 611 is provided with an embedding groove 614, and concave grooves 615 are provided on both sides of the inner wall of the embedding groove 614.

[0027] The extension mechanism 62 includes a lower right-angled plate 621 and a U-shaped connecting rod 622 fixedly installed on one side of the upper end of the lower right-angled plate 621. One end of the lower right-angled plate 621 is movably installed in the inner cavity of the embedding groove 614, the U-shaped connecting rod 622 is movably installed in the inner cavity of the through groove 612, and the installation thread 623 and the round nut 631 are threadedly connected.

[0028] In this embodiment: When the operator uses the ditching device to ditch the field, if a large amount of soil adheres to the ditching knife of the ditching device, the operator starts the driving assembly 3 to drive the sprocket assembly 4 and the brush 5 to rotate, so that the brush 5 cleans the soil attached to the surface of the ditching knife. When the brush 5 cleans the ditching knife, when the soil carried out by the brush 5 splashes, it will be directly blocked by the upper right-angled plate 611 and the lower right-angled plate 621 fixedly installed at one end of the outer wall of the ditching assembly 1, thereby reducing the splashing of soil everywhere.

[0029] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figures 2 - 4 , an installation thread 623 is embedded in the lower end of the outer surface of the U-shaped connecting rod 622, and protruding blocks 624 are fixedly installed at both ends of the outer wall of the lower right-angled plate 621.

[0030] The fixing mechanism 63 includes a round nut 631 and arc-shaped rods 632 fixedly installed at both ends of the outer wall of the round nut 631. A ring 633 is fixedly installed at the upper end of the arc-shaped rod 632, and the ring 633 is arranged to drive the arc-shaped rod 632 and the round nut 631 to rotate.

[0031] In this embodiment: The operator can adjust the position of one end of the lower right-angled plate 621 in the inner cavity of the upper right-angled plate 611 according to his own usage situation, so that the U-shaped connecting rod 622 on one side of the upper end of the lower right-angled plate 621 is slidably installed in the inner cavity of the through groove 612. After determining the set length of the lower right-angled plate 621, the operator can drive the arc-shaped rod 632 and the round nut 631 to rotate by rotating the ring 633, so that the round nut 631 threadedly presses the lower right-angled plate 621 against the upper end of the notch of the through groove 612 for fixing, thereby completing the position fixing of the lower right-angled plate 621. When the lower right-angled plate 621 is slidably installed in the inner cavity of the embedding groove 614, the protruding blocks 624 fixedly installed on both sides of the outer wall of the lower right-angled plate 621 are slidably installed in the inner cavity of the concave groove 615, and the lower right-angled plate 621 is limited and guided to slide through the arrangement of the protruding blocks 624.

[0032] Working principle: If a large amount of soil adheres to the ditching knife of the ditching device, start the driving component 3 to drive the sprocket component 4 and the brush 5 to rotate, so that the brush 5 cleans the soil adhering to the surface of the ditching knife. When the soil brought out by the brush 5 during the cleaning of the ditching knife splashes, it will be directly blocked by the upper right-angle plate 611 and the lower right-angle plate 621 fixedly installed at one end of the outer wall of the ditching component 1, thereby reducing the splashing of soil everywhere. At the same time, the operator can adjust the position of one end of the lower right-angle plate 621 in the inner cavity of the upper right-angle plate 611 according to his own usage situation, so that the U-shaped connecting rod 622 on one side of the upper end of the lower right-angle plate 621 is slidably installed in the inner cavity of the through groove 612. After determining the set length of the lower right-angle plate 621, the operator can rotate the ring 633, so that the ring 633 drives the arc rod 632 and the round nut 631 to rotate, thereby enabling the round nut 631 to threadedly press the lower right-angle plate 621 against the upper end of the notch of the through groove 612 for fixation, thus completing the fixation of the position of the lower right-angle plate 621. When the lower right-angle plate 621 is slidably installed in the inner cavity of the embedding groove 614, the protruding blocks 624 fixedly installed on both sides of the outer wall of the lower right-angle plate 621 are slidably installed in the inner cavity of the concave groove 615, and the lower right-angle plate 621 is limited and guided to slide through the arrangement of the protruding blocks 624.

[0033] The structures and working principles of the ditching component 1, the driving component 3, and the sprocket component 4 are the same as those of the mounting plate, driving motor, driving sprocket, mounting member, connecting rod, brush, driven sprocket, chain, sector gear, fixing member, mounting rod, complete gear, double-sided rack plate, bidirectional threaded rod, mounting block, sliding block, fitting plate, limiting rod, limiting groove, compression spring, limiting block, ditching knife, and pull rod in the patent with publication number CN220629972U, and will not be elaborated here.
