Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, specifically a pond-dredging mechanism. Background Technology
[0002] In most crop cultivation processes, digging trenches (creating pits of suitable size and depth) is an essential step. First, the farmland is plowed, then trenches and trenches are dug in the loosened soil, followed by sowing and fertilization. Traditionally, digging trenches by hand is time-consuming, labor-intensive, and inefficient.
[0003] Application publication number CN220140118U discloses a combined corn planting pit-clearing machine, including a pit-clearing component, a ditching component, and a connecting frame. The connecting frame includes a horizontal bar and a vertical bar. The horizontal bar includes a vertical bar connecting sleeve and support arms welded to the left and right sides of the vertical bar connecting sleeve. The horizontal bar is sleeved onto the front section of the vertical bar through the vertical bar connecting sleeve. The ditching component includes a ditching shovel and a ditching shovel connector. The ditching shovel connector includes a welded rod sleeve and a shovel sleeve. The shovel handle of the ditching shovel is inserted into the shovel sleeve and fixed by bolts. The rod sleeve is sleeved onto the outer sections of the left and right support arms of the horizontal bar and fixed by bolts. The ditching shovel is symmetrically arranged on both sides of the horizontal bar. The pit-clearing component includes a pit-clearing shovel and a pit-clearing shovel connector. The pit-clearing shovel connector is connected to the rear end of the vertical bar. The pit-clearing shovel is symmetrically arranged on both sides of the pit-clearing shovel connector. The front end of the vertical bar is provided with a pin hole for connection with a tiller. The aforementioned trenching machine is moved forward by being dragged by a mini-tiller. The trenching shovels fixed to both sides of the crossbar create two neat trenches during movement. As the shovels advance, they are subjected to friction from the soil, causing them to rotate in a circular motion from back to front on a vertical plane. This rotation also drives the other shovels to rotate, so that when they come into contact with the soil, their tips penetrate the raised beds, creating intermittently spaced trenches. Because the trenching shovels are horizontally arranged plate-like structures, the trenching machine experiences significant forward resistance during trenching, which can easily lead to deformation of the machine itself and its connecting frame, thus affecting its service life. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a trenching mechanism with lower resistance.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a pond-digging mechanism, including a connecting frame, a pond-digging component, and trenching components arranged on both sides of the front end of the connecting frame. The pond-digging component is at least one set, and the pond-digging component includes a central shaft and at least two pond-digging shovels arranged circumferentially on the central shaft. The central shaft is horizontally installed at the rear end of the connecting frame and rotatably connected to the connecting frame. The trenching component is a conical structure with its tip facing forward of the connecting frame, and the two sides of the conical structure form guide surfaces for dividing soil to both sides of the trenching component.
[0006] Furthermore, the grooved component is inclined downwards.
[0007] Furthermore, the grooved component is a triangular pyramid structure, with a hollow bottom and an open tail.
[0008] Furthermore, the grooved component is provided with support rods supporting the two sides inside.
[0009] Furthermore, the pitting assembly consists of two sets, symmetrically arranged on both sides of the rear end of the connecting frame.
[0010] Furthermore, the shovel is an arc-shaped structure that bends forward along the rotation direction of the central axis.
[0011] Furthermore, the trenching components are slidably connected to the connecting frame in the lateral direction by sliding members that are mounted on the connecting frame and slidably connected to the connecting frame in the lateral direction of the connecting frame. The sliding members are provided with a first locking mechanism for locking the lateral position of the corresponding trenching component.
[0012] Furthermore, the grooved component is vertically slidably connected to the corresponding sliding component, and the sliding component is provided with a second locking mechanism for locking the height position of the corresponding grooved component.
[0013] Furthermore, the central shaft is a hollow shaft, and the connecting frame is provided with a horizontal shaft that is arranged laterally and rotatably connected to it. The central shaft is sleeved on the horizontal shaft, and the central shaft is provided with a screw or bolt with one end connected to the horizontal shaft to fix the central shaft.
[0014] The beneficial effects of this utility model are as follows: The trenching mechanism of this utility model sets the trenching component 2 as a conical structure with the tip of the cone facing forward of the connecting frame 1. The two sides of the conical structure form guiding surfaces 21 that spread the soil to both sides of the trenching component 2. The trenching component 2 is easier to break the soil and open trenches during its forward movement, and it experiences less resistance and better force. Therefore, it and the connecting frame and other structures are relatively less prone to deformation during the trenching process, which helps to improve the service life of the trenching mechanism and ensure the trenching effect.

[0015] Figure 1 This is a schematic diagram of the structure of this utility model;
[0016] Figure 2 yes Figure 1 Top view;
[0017] The figure shows: connecting frame 1, trenching component 2, pond-digging component 3, sliding component 4, first locking mechanism 5, second locking mechanism 6, vertical rod 11, horizontal rod 12, horizontal shaft 13, guide surface 21, support rod 22, mounting rod 23, pond-digging shovel 31, and central shaft 32. Detailed Implementation
[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0019] like Figure 1 , Figure 2 As shown, the pit-digging mechanism of this utility model includes a connecting frame 1, a pit-digging assembly 3, and trenching components 2 disposed on both sides of the front end of the connecting frame 1. Specifically, similar to existing structures, the trenching component 2 is provided with a vertically arranged mounting rod 23, and the trenching component 2 is mounted on the connecting frame 1 via the mounting rod 23. In this utility model, the pit-digging assembly 3 is at least one set; the pit-digging assembly 3 includes a central shaft 32 and at least two pit-digging shovels 31 arranged circumferentially on the central shaft 32; the central shaft 32 is horizontally (horizontally and perpendicular to the direction of the line connecting the front and rear ends of the connecting frame) mounted at the rear end of the connecting frame 1 and rotatably connected to the connecting frame 1; the trenching component 2 is a conical structure with its tip facing forward of the connecting frame 1, and the two sides of the conical structure form guide surfaces 21 for dividing soil to both sides of the trenching component 2.
[0020] The connecting frame 1 can be welded from plates or rods. In this embodiment of the present invention, the connecting frame 1 is welded from rods, including a longitudinal rod 11 and a crossbar 12 disposed at the front end of the longitudinal rod 11.
[0021] The working principle of the pit-making mechanism of this utility model is the same as that of the existing combined corn planting pit-making machine: when making pits, the front end of the pit-making mechanism connecting frame 1 is connected to the micro-tiller, so that the pit-making mechanism is moved forward by the micro-tiller. The ditching shovels set on both sides of the front end of the connecting frame make two neat ditches during the movement. During the forward movement, due to the friction of some pit-making shovels 31 with the soil, the pit-making component can rotate from back to front on the vertical plane through the central shaft 32. In this way, the remaining pit-making shovels on the central shaft that are not subject to friction can insert into the soil during the rotation and forward movement to make pits at intervals. In this utility model, the ditching component 2 is set as a conical structure with the cone tip facing forward of the connecting frame 1. The two sides of the conical structure form guide surfaces 21 for parting the soil to both sides of the ditching component 2. The ditching component 2 is easier to break the soil and make ditches during the forward movement, with less resistance and better force. Therefore, it and the connecting frame and other structures are relatively less prone to deformation during the ditching process, which is conducive to improving the service life of the pit-making mechanism and ensuring the ditching effect.
[0022] The specific number of pond-digging shovels 31 on the central shaft 32 can be set as needed. Under the same conditions, the more pond-digging shovels 31 are set on the central shaft 32, the smaller the spacing between the ponds created by the pond-digging mechanism. In this embodiment of the invention, four pond-digging shovels 31 are provided on the central shaft 32. It can be understood that the pond-digging shovels 31 should generally be evenly arranged around the central shaft 32.
[0023] The grooved component can be positioned horizontally forward, meaning the cone tip of the grooved component faces horizontally forward. In this embodiment of the invention, as shown... Figure 1 As shown, the trenching component 2 is inclined downwards, meaning the tip of the trenching component 2 faces downwards. Compared to a trenching component that is horizontally forward, the downward-inclined trenching component 2 experiences a greater downward force during trenching, which not only facilitates deeper trenching but also aids in the digging of the pit by the pit digger 31. The downward inclination angle of the trenching component 2 is generally within 30°.
[0024] The grooved part 2 can be a conical, semi-conical, or triangular pyramidal structure. For example... Figure 1 and Figure 2 As shown, to facilitate trenching and soil separation, the trenching component 2 is preferably a triangular pyramid structure. When the trenching component 2 is a triangular pyramid structure, preferably, the bottom of the trenching component 2 is hollow, and the tail of the trenching component 2 is open, to reduce the resistance when the trenching component 2 initially penetrates the soil. In addition, this structure can also reduce the weight of the trenching component 2, saving materials and reducing manufacturing costs. The trenching component 2 can be formed by bending a triangular plate along its centerline, thus creating a structure with a hollow bottom and an open tail.
[0025] To prevent the trenching component 2 from deforming, the trenching component 2 is provided with support rods 22 supporting the two sides inside.
[0026] The number of pond-dredging components 3 on the pond-dredging mechanism can be one or more sets, depending on the needs. In this embodiment of the present invention, there are two sets of pond-dredging components 3, symmetrically arranged on both sides of the rear end of the connecting frame 1.
[0027] The pond-digging shovel 31 can adopt a straight plate structure, an arc-shaped structure, or an L-shaped structure, etc. For ease of pond digging, the pond-digging shovel 31 is an arc-shaped structure that bends forward along the rotation direction of the central axis 32. For example... Figure 1 As shown, the central shaft 32 rotates clockwise when working, and the shovel 31 is an arc-shaped structure that bends forward in a clockwise direction.
[0028] The furrowing components can be installed on the connecting frame 1 with a non-adjustable spacing, such as by welding the furrowing components to the connecting frame. Since different crops have different requirements for furrow spacing, to facilitate adjustment of the furrow spacing according to actual conditions, in this invention, preferably, the furrowing components 2 are slidably connected to the connecting frame 1 laterally via sliding members 4 that are mounted on the connecting frame 1 and slidably connected to the connecting frame 1 in the lateral direction of the connecting frame 1. The sliding members 4 are provided with a first locking mechanism 5 for locking the lateral position of the corresponding furrowing component 2. When it is necessary to adjust the furrow spacing, the first locking mechanisms 5 on both sides are released, and the sliding members 4 are moved to both sides respectively, causing the furrowing components 2 on both sides to move outwards, thereby increasing the distance between the furrowing components 2 and increasing the furrow spacing. The first locking mechanism 5 can be a pin, screw, or bolt, etc.
[0029] The trenching component 2 and the sliding component 4 can be connected by welding or other methods. However, this connection method cannot adjust the position and height of the trenching component 2 according to actual conditions, and therefore cannot adjust the trenching depth. Since the required trenching depth may vary under different conditions—for example, in areas with high water content, a deeper trench is required for drainage—it is preferable that the trenching component 2 and the corresponding sliding component 4 are vertically slidably connected. The sliding component 4 is equipped with a second locking mechanism 6 for locking the height position of the corresponding trenching component 2. When it is necessary to adjust the opening depth, the second locking mechanism 6 is released, and the trenching component 2 is slid up or down to adjust its position and height, thus adjusting the trenching depth. The second locking mechanism 6 can be a pin, screw, or bolt, etc.
[0030] In this embodiment of the utility model, the sliding member 4 adopts the existing cross fastener, and the first locking mechanism 5 and the second locking mechanism 6 are both bolts.
[0031] The central shaft 32 can be directly rotatably connected to the connecting frame 1 via a bearing seat that rotatably engages with it. In this embodiment of the invention, the central shaft 32 is a hollow shaft, and the connecting frame 1 is provided with a transversely arranged and rotatably connected horizontal shaft 13. The central shaft 32 is sleeved on the horizontal shaft 13, and the central shaft 32 is provided with a screw or bolt at one end connected to the horizontal shaft 13 to fix the central shaft 32. With the above structure, when it is necessary to replace the pit-drilling component, it is only necessary to remove the screw or bolt connected to the horizontal shaft 13 to remove the pit-drilling component from the horizontal shaft 13, making the disassembly and replacement of the pit-drilling component convenient.
