Description

Technical Field

[0001] This invention relates to the field of pruning, and more particularly to a tracked tea tree pruning machine suitable for hilly areas. Background Technology

[0002] The tea tree pruning machine is a pruning technique for aging tea trees, enabling them to regenerate and increase yield. A current Chinese patent application (201810578266.2, "A Tea Tree Pruning Machine") describes a machine that uses multiple sets of cutters arranged from top to bottom to cut tea tree branches into sections, which are then directly returned to the field for continuous cutting and returning, achieving high efficiency. However, one of the most common problems during this process is tearing at the cut, a significant cause of tea tree death after pruning. Although this patented machine uses a different cutting method than manual cutting to reduce this problem, in actual cutting, the aging and hardening of tea tree branches, and wear and tear on the cutters can still lead to significant tearing. Summary of the Invention

[0003] To overcome the drawback that tearing problems may occur during actual cutting due to factors such as the aging and hardening of tea tree branches and wear of the cutting blade, this invention provides a tracked tea tree replanting machine suitable for hilly areas.

[0008] Preferably, the push plate is set to have the same tilt angle as the saw blade, and the height of the push plate is higher than the height of the saw blade, and the push plate is located on the left side of the saw blade.

[0009] Preferably, the height of the pull plate is higher than the highest point of the saw blade.

[0010] Preferably, the assembly also includes a first elastic element, a connecting plate, a fixing frame, a second elastic element, a pressure plate, and a cam; a first elastic element is fixedly connected to both the front and rear sides of the mounting frame; a connecting plate is fixedly connected to the telescopic end of each first elastic element; a fixing frame is installed between the two connecting plates; multiple second elastic elements are arranged equidistantly from front to back on the fixing frame; a pressure plate is installed at the telescopic end of each second elastic element to press down the remaining branches at the cut; a cam is installed on the output shaft of the crushing roller.

[0011] Preferably, it also includes a hollow plate, a compression plate, and an air blowing plate; the hollow plate is fixedly connected to the lower side of the mounting frame, and the hollow plate is provided with a one-way air inlet that allows air to enter in only one direction; the compression plate is fixedly connected to the fixed frame; multiple air blowing plates for blowing away leaves and other impurities at the cut are arranged sequentially from front to back on the lower side of the fixed frame, and the air blowing plates are vented to the lower left.

[0013] As a preferred option, a wind deflector is provided on both the front and rear sides of the mounting bracket.

[0014] The beneficial effects of the present invention are as follows: The present invention achieves the use of a saw disc set at an angle and a pull plate to apply a rightward pulling force to the branches, causing the lower side of the branches to gradually bend to the right, thereby pruning in an angled manner, avoiding the lateral pulling of the fibers and effectively reducing the risk of tearing. The branches are crushed by crushing rollers, thus achieving the effect of rapid return to the field; By moving the pressure plate up and down, it presses down any remaining twigs and other debris, preventing them from remaining at the cut and instead pressing them into the rootstock, thus ensuring ease of subsequent operations. By blowing air to the left through the air blowing plate, the leaves are blown to the left or directly blown down between the roots and stems, so that when the liquid is delivered from the storage tank to the infusion tube and the diversion plate, and sprayed out from the outlet, it will not be blocked by the leaves. Wind deflectors are installed on both sides of the fixed frame to block the airflow and prevent the liquid medicine from being blown away. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: See also Figures 1-11 .

[0018] Example 1

[0019] A tracked tea tree replanting machine suitable for hilly areas, such as Figures 1-5 As shown, it includes a tracked travel mechanism 1 and a mounting frame 2; the tracked travel mechanism 1 is set to solve the problem that the wheels may easily tip over or get stuck in the mud in hilly areas due to the large slope or soft soil; the tracked travel mechanism 1 is equipped with a mounting frame 2. It also includes a drive unit 101, a retracting plate 102, a pulling plate 103, a saw disc 104, and a drive motor 105; two drive units 101 are provided on the lower side of the mounting frame 2, and the drive unit 101 is an electric push rod; the output ends of the two drive units 101 are jointly mounted with the retracting plate 102 through a fixing plate; several pulling plates 103 are jointly mounted with the output ends of the two drive units 101 through a fixing plate; the saw disc 104 and the drive motor 105 are provided on the mounting frame 2, and the drive motor 105 is connected to the saw disc 104 through a pulley and transmits power to it.

[0020] There are two gathering plates 102, one on each side of the travel mechanism 1 in the width direction, and the distance between the two is greater than the width of the tea tree planting.

[0021] The pull plate 103 is provided with multiple arc-shaped pieces arranged in sequence, and the bending direction of the arc-shaped pieces is along... Figure 1 It bends to the right in the direction shown.

[0022] The saw blade 104 is set to be inclined at an acute angle to the pull plate 103; it also includes a push plate 106 and a crushing roller 107; the push plate 106 is fixedly connected to the left side of the mounting frame 2; a hollow chamber 2001 is provided in the middle of the mounting frame 2, and the crushing roller 107 is installed in the hollow chamber 2001.

[0023] The push plate 106 is set to have the same tilt angle as the saw disc 104, and the height of the push plate 106 is higher than the height of the saw disc 104. The push plate 106 is located at... Figure 4 The direction shown is to the left of the saw blade 104; the height of the pull plate 103 is higher than the highest point of the saw blade 104.

[0024] When the tea bushes are replanted, the pruning machine moves from right to left. The tea bushes are planted in an alternating pattern. The tracked traveling mechanism 1 moves along the aisles between adjacent tea bushes. At the start of pruning, the tracked traveling mechanism 1 drives the entire machine to move slowly. During the pruning process, such as... Figure 3As shown, the pull plate 103 gradually inserts between adjacent branches. After insertion, the tracked travel mechanism 1 continues to move slowly forward. Simultaneously, the drive unit 101 synchronously drives the pull plate 103 to move to the right. At this time, the saw disc 104 moves to the left, gradually contacting the root of the branch and beginning the cutting operation. During this process, as the pull plate 103 moves to the right, it gradually pulls the branch, subjecting it to a rightward pulling force. The lower side of the branch gradually bends to the right. At the same time, when the saw disc 104 contacts the lower side of the branch, the two contact at a certain angle, and the angle is upward. At this time, during the cutting process, unlike the vertical cutting method, where the movement direction of the blade is completely perpendicular to the stem fiber, the force directly "pulls" the fiber. When cutting into the coarse, hard, and unevenly tough wood, the huge lateral pulling force will seek the weakest fiber interface and tear the bark along the fiber direction, causing tearing. However, during the inclined cutting, the force acting on the fiber is decomposed. Its core is the "sliding cut" effect: the blade, like a sharp knife, "slides" across the fiber at a certain angle, generating a shearing force that is more conducive to cutting, avoiding the lateral pulling of the fiber. Therefore, when cutting at an inclined angle, the risk of tearing can be effectively reduced. At the same time, after the cutting is completed, the side of the cut branch is pulled to the right by the pull plate 103, and its cut part contacts the push plate 106 and is pushed to the left by the push plate 106, causing it to gradually fall to the right. Moreover, since the pull plate 103 is located in the middle and lower part of the branch, it can smoothly ensure that the cut branch falls directly to the right. As the track travel mechanism 1 continues to move to the left, the branch falling to the right is rolled into and crushed by the crushing roller 107, thereby achieving the effect of rapid return to the field. During the pruning process, the above process is repeated to achieve the whole row pruning operation.

[0025] Example 2

[0026] Based on Example 1, such as Figure 1 , Figure 6 and Figure 7 As shown, it also includes a first elastic element 201, a connecting plate 202, a fixing frame 203, a second elastic element 204, a pressure plate 205, and a cam 206; a first elastic element 201 is fixedly connected to both the front and rear sides of the mounting frame 2, and the first elastic element 201 is a spring telescopic plate; a connecting plate 202 is fixedly connected to the telescopic end of each first elastic element 201; a fixing frame 203 is installed between the two connecting plates 202; multiple second elastic elements 204 are arranged equidistantly from front to back on the fixing frame 203, and the second elastic elements 204 are spring telescopic plates; a pressure plate 205 is installed at the telescopic end of each second elastic element 204; a cam 206 is installed on the output shaft of the crushing roller 107.

[0027] The surface of the pressure plate 205 is covered with rubber material, and the lowest point of the pressure plate 205 is higher than the highest point of the saw blade 104.

[0028] During pruning, a small number of twigs may remain at the cut. To prevent bacterial infection and facilitate subsequent spraying of protective liquid, cleaning is necessary, which is difficult to do manually. Therefore, as the tracked traveling mechanism 1 continues to move to the left, the cam 206 follows the rotation of the crushing roller 107, and the cam 206 continuously strikes the connecting plate 202, causing the first elastic element 201 to repeatedly stretch and compress. At the same time, the fixed frame 203, the second elastic element 204, and the pressure plate 205 all move up and down synchronously. During this process, as the pressure plate 205 moves up and down, it presses down the remaining twigs, preventing them from remaining at the cut and instead pressing them into the roots, ensuring the convenience of subsequent operations. Meanwhile, to prevent the pressure plate 205 from damaging the cut, its surface is covered with rubber for protection. In addition, by setting the second elastic element 204, the pressure plate 205 has a certain buffer distance, thus avoiding direct hard compression of the cut and causing unnecessary damage.

[0029] Example 3

[0030] Based on Example 2, such as Figure 1 , Figures 8-11 As shown, it also includes a hollow plate 301, a compression plate 302 and an air blowing plate 303; the hollow plate 301 is fixedly connected to the lower side of the mounting frame 2; the compression plate 302 is fixedly connected to the fixed frame 203, and the air inside the hollow plate 301 is compressed by the compression plate 302; multiple air blowing plates 303 are arranged sequentially from front to back on the lower side of the fixed frame 203.

[0031] It also includes a liquid storage tank 401, infusion tubes 402 and a diverter plate 403; the liquid storage tank 401 is provided on the right side of the mounting frame 2; multiple infusion tubes 402 are connected to the liquid storage tank 401; the diverter plate 403 is fixedly connected to the fixed frame 203, and all infusion tubes 402 are connected to the diverter plate 403; the fixed frame 203 has several liquid outlets 20302, and the liquid outlets 20302 are connected to the diverter plate 403.

[0032] A baffle plate 20301 is provided on both the front and rear sides of the fixed frame 203 to prevent the liquid from being disturbed by external airflow during the spraying process, thus affecting the uniformity.

[0033] After pruning, the cut surface needs to be sprayed with a protective solution. However, to prevent leaves from obscuring the cut and to avoid external wind affecting the uniformity of the spray, during the spraying process, as the fixing frame 203 moves up and down, the compression plate 302 moves up and down in sync, thereby compressing the gas inside the hollow plate 301 and blowing it out from multiple air blowing plates 303 in a leftward direction. This blows the leaves to the left or directly down between the roots and stems, so that when the liquid storage tank 401 delivers the liquid to the infusion pipe 402 and the diversion plate 403 and sprays it out from the outlet 20302, it will not be obstructed by the leaves. At the same time, to avoid interference from external airflow, wind deflectors 20301 are set on both sides of the fixing frame 203 to block the airflow and prevent the liquid from being blown away.
