Description

Technical Field

[0001] This utility model relates to the technical field of fruit tree fertilization equipment, specifically to an arc-shaped trenching fertilization machine. Background Technology

[0002] Currently, tree fertilization mainly involves manual fertilization and mechanical fertilization. Manual fertilization requires digging holes by hand and covering the soil after fertilization, which is costly and inefficient. Therefore, the industry is currently pursuing mechanical fertilization.

[0003] However, current mechanical fertilization uses strip fertilization, that is, the fertilizer applicator moves in a straight line and the fertilization line is strip-shaped. For example, the fertilizer applicators disclosed in the prior art, such as CN119586408A, CN222564399U, CN222532225U, and CN222509960U, adopt the above-mentioned fertilization method.

[0004] Strip fertilization is only suitable for fruit trees with close spacing (such as vine grapes), where fertilizer waste is relatively small. However, when fertilizing large, tree-like fruit trees (such as pecans) with greater spacing (e.g., more than 3 meters), the disadvantages of strip fertilization are obvious: due to the large distance between trees, strip fertilization leads to higher fertilizer waste and lower fertilizer absorption and utilization rates. Furthermore, if the aforementioned fertilizer applicator were used to move around each fruit tree, the distance the applicator would travel would increase, raising operating costs. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide an arc-shaped trenching fertilizer applicator.

[0027] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0028] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity and not intended to limit the scope of implementation. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0029] In one embodiment, such as Figure 1As shown, this application proposes an arc-shaped trenching and fertilizing machine, including a body 101. A fertilizer storage bin is installed on the body 101 for storing fertilizer. An arc-shaped drive mechanism and a material conveying mechanism are installed on the body 101. The arc-shaped drive mechanism connects a trenching blade assembly 202 and a soil return mechanism 204, driving the trenching blade assembly 202 and the soil return mechanism 204 to move along an arc-shaped trajectory. Specifically, see... Figure 6 When the machine body 101 moves along a row of fruit trees in a straight path, the trenching knife group 202 and the soil return mechanism 204 are driven by the arc-shaped drive mechanism to move relative to the machine body 101 along the arc-shaped fertilization line. This can realize ring fertilization around each fruit tree, avoiding the problem of low fertilizer absorption and utilization rate when traditional strip fertilization is carried out on large arbor fruit trees with large trunk spacing.

[0030] The conveying mechanism is connected to the fertilizer storage bin. Fertilizer in the storage bin can be conveyed to the discharge port 203 via the conveying mechanism. The discharge port 203 is located between the trenching cutter group 202 and the soil return mechanism 204. When fertilization is carried out, the trenching cutter group 202 first digs the soil into the trench. Simultaneously, fertilizer falls into the trench from the discharge port 203. The soil return mechanism 204 moves together with the trenching cutter group 202 and can push the soil formed by the trenching into the trench, thereby covering the fertilizer and completing the fertilization operation.

[0031] Because it can perform ring fertilization, for large trees with large spacing, it can perform ring fertilization around each tree. At the same time, the movement path of the body 101 can also remain in a straight line, and the body 101 does not need to move around each tree, reducing the movement distance of the body 101.

[0032] In one optional embodiment of the arc-shaped drive mechanism, the arc-shaped drive mechanism includes a fixed rail 106 connected to the body 101. Preferably, the fixed rail 106 is fixedly connected to the body 101, for example, by welding, riveting, or bolting. The fixed rail 106 is provided with an arc-shaped slide rail, and an arc-shaped sliding rod 104 is installed in the arc-shaped slide rail. The arc-shaped sliding rod 104 can slide along the arc-shaped slide rail, and the movement path of the arc-shaped sliding rod 104 is arc-shaped.

[0033] A base 201 is installed on the arc-shaped sliding rod 104. The base 201 is fixedly connected to the arc-shaped sliding rod 104, for example, by welding or riveting. The base 201 and the arc-shaped sliding rod 104 can also be detachably connected, for example, preferably by bolts.

[0034] The trenching cutter group 202 and the soil return mechanism 204 are both installed at the lower end of the base 201, and the discharge port 203 is located on the base 201. In the arc-shaped fertilization direction, the trenching cutter group 202 is in front, the discharge port 203 is in the middle, and the soil return mechanism 204 is behind. That is, when the base 201 moves along the arc-shaped fertilization trajectory, trenching is done first, then fertilization is done, and finally soil return is done.

[0035] The arc-shaped drive mechanism also includes a power unit, which drives the arc-shaped sliding rod 104 to slide along the arc-shaped track. It should be noted that the arc-shaped sliding rod 104 only needs to slide a certain distance along the arc-shaped track; it does not need to slide along a complete circular trajectory. Once the arc-shaped sliding rod 104 has slid a certain distance, the fertilization operation is complete. At this point, the power unit drives the arc-shaped sliding rod 104 back to its original position for fertilizing the next fruit tree.

[0036] Optionally, the power unit is a hydraulic cylinder or a pneumatic cylinder, which is rotatably connected to the machine body 101 at the first hinge point 103, and the piston rod of the hydraulic / pneumatic cylinder is rotatably connected to the arc-shaped sliding rod 104 at the second hinge point 105. For example... Figure 1 As shown, when the piston rod extends, the arc-shaped sliding rod 104 moves counterclockwise. When the piston rod retracts, the arc-shaped sliding rod 104 returns to its original position along its original trajectory.

[0037] As a preferred embodiment, there are two bases 201, thus forming two fertilization lines around each fruit tree. Since the trenching blade assembly 202 and the soil-returning mechanism 204 on both bases 201 operate simultaneously, it is advisable to use the same power source to drive the trenching blade assembly 202 on both bases 201. Specifically, as... Figure 2 , 3 As shown, a bearing 304 is mounted on the base 201, and a rotating shaft 305 is installed inside the bearing 304. The rotating shaft 305 is connected to a pulley 303 and a trenching cutter assembly 202. The pulleys 303 on each base 201 are connected by a transmission belt 301. That is, when a pulley 303 on one base 201 is driven to rotate, it can drive the other pulleys 303 to rotate simultaneously via the transmission belt 301.

[0038] By setting up a pulley drive mechanism, and by connecting the pulley 303 on one of the bases 201 to the pulley drive mechanism, all the pulleys 303 on the bases 201 can be driven to rotate by a pulley drive mechanism.

[0039] Specifically, the belt pulley drive mechanism includes a motor 401 and a gearbox 402 mounted on the machine body 101. The motor 401 is connected to the gearbox 402, and the gearbox 402 is connected to the flexible shaft 403. The output end of the flexible shaft 403 is fixedly mounted on the base 201, and the output shaft of the flexible shaft 403 is connected to a first bevel gear 405. Figure 3 , 4 As shown, a second bevel gear 404 is coaxially connected to the pulley 303, and the second bevel gear 404 meshes with the first bevel gear 405. When the motor 401 is started, the flexible shaft 403 can drive the bevel gear set to rotate, thereby driving the pulley 303, which is coaxially connected to the second bevel gear 404, to rotate.

[0040] Since the base 201 moves along with the arc-shaped sliding rod 104, the flexible shaft 403 can achieve the transmission effect while the base 201 is moving. The flexible shaft 403 can be bent to a certain extent, but can also transmit torque. The flexible shaft 403 can be a type of flexible shaft widely used in existing technologies such as CN222717269U, which will not be elaborated here.

[0041] Because the drive belt 301 enables the pulleys 303 on each base 201 to rotate synchronously, the drive belt 301 will loosen when each base 201 moves along the arc-shaped fertilization line, thus failing to achieve the transmission function. Therefore, this embodiment also provides a tensioning mechanism 302, which is mounted on the machine body 101. The drive belt 301 bypasses the tensioning mechanism 302, which is used to tension the drive belt 301. Tensioning mechanisms are common in the prior art and will not be described or limited here.

[0042] Furthermore, since the base 201 is to perform circular fertilization around the tree trunk, the drive belt 301 connecting each pulley 303 may interfere with the tree trunk. Therefore, by setting a tensioning mechanism and installing the tensioning mechanism on the machine body 101, the drive belt 301 can be bent through the tensioning mechanism, thereby creating clearance space (e.g., ...). Figure 1 As shown in the figure, when fertilizing, the tree trunk is roughly located in the clearance space, which can avoid interference between the transmission belt 301 and the tree trunk.

[0043] As an optional implementation, the fixed rail 106 is provided with a limiting part, which is used to restrict the vertical displacement of the arc-shaped sliding rod 104, that is, to restrict the arc-shaped sliding rod 104 to move only in an arc-shaped trajectory on the horizontal plane, and to prevent it from making vertical displacement relative to the fixed rail 106. Figure 5 (a) The fixed rail 106 can be a circular tube with an opening, and the arc-shaped sliding rod 104 is inserted into the fixed rail 106. Or as... Figure 5 As shown in (b), the side wall of the arc-shaped sliding rod 104 is provided with a flange 104-1, and the inner wall of the fixed rail 106 is provided with a groove, with the flange 104-1 located within the groove. The groove and the flange 104-1 can restrict the vertical displacement of the arc-shaped sliding rod 104 relative to the fixed rail 106. It should be noted that the limiting part is not limited to the above embodiment; other limiting structures in the prior art that can achieve similar effects are also applicable to this application.

[0044] In one embodiment, the trenching blade assembly 202 and the backfilling blade assembly 204 are designed to operate only when they are positioned corresponding to the fruit tree; that is, the trenching blade assembly 202 performs trenching operations when the machine body 101 is positioned corresponding to the fruit tree. In this embodiment, the arc-shaped trenching fertilizer also includes a lifting platform 102, which is installed at the lower end of the machine body 101. The arc-shaped drive mechanism, the trenching blade assembly 202, and the backfilling mechanism 204 are all mounted on the lifting platform 102; that is, the first hinge point 103, the fixed rail 106, and the tensioning mechanism 302 are all mounted on the lifting platform 102. When the lifting platform 102 drives the fixed rail 106 to rise or fall, the fixed rail 106 drives the arc-shaped sliding rod 104 to rise or fall, thereby driving the trenching blade assembly 202 and the backfilling blade assembly 204 on the base 201 to rise or fall. Because the torque is transmitted using a flexible shaft 403, even if the base 201 rises or falls, it does not affect the rotation of the drive pulley 303.

[0045] During fertilization, when the machine body 101 moves to the corresponding position of the fruit tree, the lifting platform 102 drives the arc-shaped drive mechanism, the trenching blade assembly 202, and the soil return mechanism 204 to move downwards, so that the trenching blade assembly 202 contacts the ground, and then trenching, fertilization, and soil return are performed. After the fertilization operation is completed, the lifting platform 102 drives the arc-shaped drive mechanism, the trenching blade assembly 202, and the soil return mechanism 204 to move upwards, so that the trenching blade assembly 202 leaves the ground, the arc-shaped sliding rod 104 returns to its original position, and the machine body 101 moves to the corresponding position of the next fruit tree to perform the fertilization operation on the next fruit tree.

[0046] To facilitate the movement of the machine body 101, wheels can be installed at the lower end of the machine body 101. The lifting platform 102 can drive the trenching cutter group 202 to move below the contact surface between the wheels and the ground, so that trenching operations can be carried out.

[0047] In one optional embodiment, the conveying mechanism includes a metering scale and a conveying pipe connected to the metering scale, the conveying pipe being connected to the outlet 203. The metering scale can be used to set the amount of fertilizer applied each time, thereby improving fertilizer utilization and avoiding over-fertilization or under-fertilization.

[0048] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
