Description

Technical Field

[0001] This utility model relates to the field of trenching machine technology, and in particular to a trenching machine for tea planting. Background Technology

[0002] A trenching machine is a device used to create trenches on the surface of the soil during tea planting. When using a trenching machine, the operator pushes the connecting frame with a handle, which in turn drives the wheels at the bottom of the connecting frame to rotate, allowing the cutting blades at the bottom of the connecting frame to perform the trenching operation.

[0003] The inventors discovered in their daily work that trenching machines still have at least the following problems: When using a trenching machine, the operator pushes the connecting frame with a handle, which in turn drives the wheels at the bottom of the connecting frame to rotate. This allows trenching to be done through the cutter at the bottom of the connecting frame. However, in actual use, since the cutter is mostly located together with the connecting frame, it is quite troublesome to grind the cutter when needed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a ditching machine for tea planting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tea planting trenching machine, comprising a connecting frame, wheels mounted on the bottom of the connecting frame, a cutter provided at the bottom of the connecting frame, a handle provided at the top of the connecting frame, a fixing device provided at the top of the cutter, the fixing device comprising a connecting frame, the connecting frame being fixedly connected to the bottom of the connecting frame, a connecting block being slidably connected to the inner wall of the connecting frame, the bottom of the connecting block being fixedly connected to the top of the cutter, a sliding strip being fixedly connected to one side of the connecting block, a limiting groove being provided on one side of the connecting frame, the inner wall of the limiting groove being slidably connected to the sliding strip, a sliding groove being provided at the bottom of the connecting frame, a sliding frame being slidably connected to the inner wall of the sliding groove, the sliding frame being sleeved on the surface of the sliding strip, a sliding rod being fixedly connected to the inner wall of the sliding groove, and the sliding rod being slidably inserted through and inserted into one side of the sliding frame.

[0006] The effect achieved by the above components is as follows: when using the fixing device, the connecting block is slid into the inside of the connecting frame, and then the sliding strip is slid into the inside of the limiting groove. Then, the sliding frame is manually controlled to slide on the inner wall of the groove, so that the sliding frame is fitted on the surface of the sliding strip. This can effectively restrict the connecting block inside the connecting frame. Reverse operation makes it easy to disassemble the cutter, which makes it easy to grind the cutter.

[0007] Preferably, a first spring is sleeved on the surface of the sliding rod, one end of the first spring is fixedly connected to one side of the inner wall of the sliding groove, and the end of the first spring near the sliding frame is fixedly connected to one side of the sliding frame.

[0008] The effect achieved by the above components is that the sliding frame is pressed towards the cutter by the first spring, thus restricting the sliding frame to the surface of the sliding bar.

[0009] Preferably, a rubber strip is fixedly connected to the end of the sliding bar away from the connecting block, and the rubber strip is disposed on the side of the sliding frame away from the first spring.

[0010] The effect achieved by the above components is that when the sliding frame is fitted onto the surface of the sliding strip, the rubber strip is squeezed on the side of the sliding frame away from the first spring, so that the sliding frame can be restricted to the surface of the sliding strip by the rubber strip.

[0011] Preferably, the top of the connecting block is provided with a rectangular groove, the inner wall of the rectangular groove is slidably connected with a rectangular block, and the top of the rectangular block is fixedly connected to the top of the inner wall of the connecting frame.

[0012] The effect achieved by the above components is to slide the rectangular block into the inside of the rectangular groove, so that the connecting block can be tightly set inside the connecting frame.

[0013] Preferably, one end of the handle is provided with an adjustment device, the adjustment device including a cylinder, the top of the cylinder being fixedly connected to the connecting frame, and the inner wall of the cylinder being slidably connected to the bottom of the handle.

[0014] The effect achieved by the above components is that when using the adjustment device, the handle can be manually controlled to slide inside the cylinder, thus adjusting the length of the handle and making it easier for people of different body types to operate the trenching machine.

[0015] Preferably, a damping rod is fixedly connected to the bottom of the inner wall of the cylinder, and the end of the damping rod away from the cylinder is fixedly connected to the end of the handle. A second spring is sleeved on the surface of the damping rod, and one end of the second spring is fixedly connected to the bottom of the inner wall of the cylinder. The end of the second spring near the handle is fixedly connected to the end of the handle.

[0016] The effect achieved by the above components is that the handle is pressed away from the cylinder by the second spring, which makes it easier to slide the handle out of the cylinder.

[0017] Preferably, a bolt is threaded through one side of the cylinder, and the side of the bolt closest to the inner wall of the cylinder is disposed on the surface of the handle.

[0018] The effect achieved by the above components is that when the handle slides to the appropriate position on the inner wall of the cylinder, the bolt is pressed against one side of the handle, which makes it easier to confine the handle inside the cylinder.

[0019] Preferably, a rubber sleeve is fixedly connected to the end of the handle away from the cylinder, and rubber blocks are uniformly fixedly connected to the surface of the rubber sleeve.

[0020] The effect achieved by the above components is that by placing the rubber sleeve on the end surface of the handle away from the cylinder and evenly distributing the rubber blocks on the surface of the rubber sleeve, the friction is increased to a certain extent, which can prevent the operator's hand from slipping and affecting the operation.

[0021] In this utility model, by setting a fixing device, when using the fixing device, the connecting block is slid into the inside of the connecting frame, and then the sliding strip is slid into the inside of the limiting groove. Then, the sliding frame is manually controlled to slide on the inner wall of the groove, so that the sliding frame is fitted on the surface of the sliding strip. This can effectively restrict the connecting block inside the connecting frame. Reverse operation makes it easy to disassemble the cutter, which is convenient for grinding the cutter.

[0027] Example 1, such as Figure 1-4As shown, a tea planting trenching machine has wheels 3 installed at the bottom of the connecting frame 1, a cutter 2 at the bottom of the connecting frame 1, a handle 4 at the top of the connecting frame 1, and a fixing device 5 at the top of the cutter 2. When using the trenching machine, the operator pushes the connecting frame 1 through the handle 4, which in turn drives the wheels 3 at the bottom of the connecting frame 1 to rotate, so that the trenching operation can be performed through the cutter 2 at the bottom of the connecting frame 1.

[0028] Reference Figure 2 and Figure 3 The fixing device 5 includes a connecting frame 501, which is fixedly connected to the bottom of the connecting bracket 1. A connecting block 502 is slidably connected to the inner wall of the connecting frame 501. The bottom of the connecting block 502 is fixedly connected to the top of the cutter 2. A sliding strip 503 is fixedly connected to one side of the connecting block 502. A limiting groove 504 is formed on one side of the connecting frame 501. The inner wall of the limiting groove 504 is slidably connected to the sliding strip 503. A sliding groove 506 is formed at the bottom of the connecting bracket 1. A sliding frame 507 is slidably connected to the inner wall of the sliding groove 506. The sliding frame 507 is fitted onto the surface of the sliding strip 503. A sliding rod 508 is fixedly connected to the inner wall of the groove 506. The sliding rod 508 is slidably inserted through one side of the sliding frame 507. When using the fixing device 5, the connecting block 502 is slid into the inside of the connecting frame 501, and then the sliding strip 503 is slid into the inside of the limiting groove 504. Then, the sliding frame 507 is manually controlled to slide on the inner wall of the groove 506, so that the sliding frame 507 is fitted onto the surface of the sliding strip 503. This can effectively restrict the connecting block 502 inside the connecting frame 501. Reverse operation makes it easy to disassemble the cutter 2, which facilitates the removal of the cutter 2. The surface of the sliding rod 508 is fitted with a first spring 509. One end of the first spring 509 is fixedly connected to one side of the inner wall of the slide groove 506, and the end of the first spring 509 near the sliding frame 507 is fixedly connected to one side of the sliding frame 507. The first spring 509 presses the sliding frame 507 towards the cutter 2, thus restricting the sliding frame 507 to the surface of the sliding strip 503. A rubber strip 505 is fixedly connected to the end of the sliding strip 503 away from the connecting block 502. The rubber strip 505 is located on the side of the sliding frame 507 away from the first spring 509. When the sliding... When frame 507 is fitted onto the surface of sliding strip 503, rubber strip 505 is pressed against the side of sliding frame 507 away from the first spring 509. In this way, sliding frame 507 can be restricted to the surface of sliding strip 503 by rubber strip 505. Rectangular groove 510 is provided on the top of connecting block 502. Rectangular block 511 is slidably connected to the inner wall of rectangular groove 510. The top of rectangular block 511 is fixedly connected to the top of inner wall of connecting frame 501. Sliding rectangular block 511 into the inside of rectangular groove 510 allows connecting block 502 to be tightly set inside connecting frame 501.

[0029] Reference Figure 4 An adjustment device 6 is provided at one end of the handle 4. The adjustment device 6 includes a cylinder 601, which is fixedly connected to the top of the connecting frame 1. The inner wall of the cylinder 601 is slidably connected to the bottom of the handle 4. When using the adjustment device 6, the handle 4 is manually controlled to slide within the inner wall of the cylinder 601, thus adjusting the length of the handle 4 to facilitate operation of the trenching machine by people of different body types. A damping rod 602 is fixedly connected to the bottom of the inner wall of the cylinder 601. The end of the damping rod 602 away from the cylinder 601 is fixedly connected to one end of the handle 4. A second spring 603 is sleeved on the surface of the damping rod 602. One end of the second spring 603 is fixedly connected to the bottom of the inner wall of the cylinder 601, and the end of the second spring 603 near the handle 4 is fixedly connected to one end of the handle 4. The second spring 603 is used to adjust the handle 4 towards the cylinder 601. The handle 4 is pressed in the direction of 1, which makes it easier to slide the handle 4 out of the inside of the cylinder 601. A bolt 604 is threaded through one side of the cylinder 601. The side of the bolt 604 near the inner wall of the cylinder 601 is set on the surface of the handle 4. When the handle 4 slides to a suitable position on the inner wall of the cylinder 601, the bolt 604 presses against one side of the handle 4, which helps to confine the handle 4 inside the cylinder 601. A rubber sleeve 605 is fixedly connected to the end of the handle 4 away from the cylinder 601. Rubber blocks 606 are evenly fixedly connected to the surface of the rubber sleeve 605. The rubber sleeve 605 is set on the surface of the end of the handle 4 away from the cylinder 601, and the rubber blocks 606 are evenly distributed on the surface of the rubber sleeve 605. This increases the friction to a certain extent and prevents the operator's hand from slipping and affecting the operation.

[0030] Working principle: When using the trencher, the operator pushes the connecting frame 1 with handle 4, which in turn rotates the wheel 3 at the bottom of the connecting frame 1. This allows the cutting blade 2 at the bottom of the connecting frame 1 to perform trenching. When using the fixing device 5, the connecting block 502 is slid into the connecting frame 501, and the rectangular block 511 is slid into the rectangular groove 510. This ensures that the connecting block 502 is tightly fitted inside the connecting frame 501, and the sliding strip 503 is slid into the limiting groove 504. Then, the sliding frame 507 is manually controlled to slide on the inner wall of the sliding groove 506, so that the sliding frame 507 is fitted onto the surface of the sliding strip 503. The first spring 509 presses the sliding frame 507 towards the cutting blade 2. When the sliding frame 507 is fitted onto the surface of the sliding strip 503, the rubber strip 505 is pressed onto the side of the sliding frame 507 away from the first spring 509. This limits the sliding frame 507 with the rubber strip 505. The sliding strip 503 is positioned on the surface of the sliding strip, which effectively confines the connecting block 502 inside the connecting frame 501. Reverse operation facilitates the disassembly of the cutter 2, making it easier to grind the cutter 2. When using the adjustment device 6, the handle 4 is manually controlled to slide within the inner wall of the cylinder 601. The second spring 603 presses the handle 4 away from the cylinder 601, making it easier to slide the handle 4 out of the cylinder 601. When the handle 4 slides to the appropriate position within the inner wall of the cylinder 601, the bolt 604 presses against one side of the handle 4, thus confining the handle 4 inside the cylinder 601. This allows for adjustment of the length of the handle 4, making it easier for people of different body types to operate the trencher. The rubber sleeve 605 is placed on the surface of the handle 4 away from the cylinder 601, and rubber blocks 606 are evenly distributed on the surface of the rubber sleeve 605, increasing friction and preventing the operator's hand from slipping and affecting operation.

[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
