A seedling mulching and frost protection machine

Abstract

This invention relates to the field of seedling mulching technology, and more particularly to a seedling mulching and frost protection machine. The seedling mulching and frost protection machine includes a connecting rod, a pushing mechanism, and a compaction mechanism. The connecting rod is located on the front side of the tree trunk, and is equipped with a pushing mechanism for pushing the surrounding soil to the bottom of the trunk. The pushing mechanism is equipped with a compaction mechanism for compacting the soil. This invention uses a ring claw that rotates inward to push the surrounding soil to the bottom of the trunk. The inward rotation of the ring claw causes a pressure rod to move backward, which in turn pushes a pressure cap downward to compact the soil, thereby completing the mulching work on the tree trunk.

Description

Technical Field

[0001] This invention relates to the field of seedling soil covering technology, and in particular to a seedling soil covering and frost protection machine. Background Technology

[0002] Northern winters are characterized by cold, windy, and dry weather with drastic climate changes, posing a significant threat to seedlings, especially those with weak cold resistance and poor lignification. To ensure seedling survival rates, proper winter protection measures are essential. Common methods include watering before freezing, whitewashing, and covering with soil. Covering with soil involves burying the seedlings in the soil throughout the winter, maintaining a certain temperature for both the seedlings and the seedbed soil. This protects them from drastic temperature changes and other adverse external factors. Simultaneously, it reduces water transpiration from the seedlings and evaporation from the soil, maintaining a certain level of soil moisture and helping to maintain the seedlings' water balance. This effectively prevents death caused by frost damage and physiological drought. However, current techniques for covering seedlings with soil mostly involve manually shoveling soil to the base of the seedlings and then compacting it. This method is not only time-consuming and labor-intensive but also requires a large workforce.

[0003] To address the problems existing in the above-mentioned technologies, we have designed a seedling mulching and frost protection machine. Summary of the Invention

[0004] In order to overcome the shortcomings of existing technologies that mostly involve manually shoveling soil to the base of seedlings and then compacting it, which is not only time-consuming and labor-intensive, but also requires a large amount of manpower, the technical problem of this invention is to provide a seedling soil covering and frost protection machine.

[0005] A seedling mulching and frost protection machine includes a connecting rod, a soil pushing mechanism, and a compaction mechanism. The connecting rod is located on the front side of the tree trunk, and the connecting rod is equipped with a soil pushing mechanism for pushing the surrounding soil to the bottom of the tree trunk. The soil pushing mechanism is equipped with a compaction mechanism for compacting the soil.

[0006] As an improvement to the above solution, the bulldozing mechanism includes a ring claw, a rotating shaft, a hydraulic cylinder, a push plate, and a tie rod. A hydraulic cylinder is installed at the rear of the connecting rod, and a push plate is connected to the telescopic rod of the hydraulic cylinder. Tie rods are rotatably connected to both sides of the push plate. A rotating shaft is connected to the rear of the connecting rod, and a ring claw is rotatably connected to the rotating shaft. The ring claws clamp each other, and the rear of the tie rods are rotatably connected to the ring claws on the same side.

[0007] As an improvement to the above solution, the compaction mechanism includes a pressure rod, a first spring, a pressure cap, and a slider. Pressure caps are slidably connected to both sides of the inner wall of the annular claw, and sliders are slidably connected to the pressure caps. The sliders on the same side are connected to the annular claws with the first springs. Pressure rods are slidably connected between the annular claws. The pressure rods are in contact with the pressure caps. A pressure groove is opened at the front of the annular claws, and the pressure rods slide on the pressure groove.

[0008] As an improvement to the above solution, the caps form a frustum shape after contacting each other, which is used to compact the soil at the base of the tree trunk.

[0009] As an improvement to the above solution, a leveling mechanism is also included to evenly distribute the soil around the tree trunk. The leveling mechanism includes a guide rod and a scraper. The inner side of the ring claw is opened with a groove, which is Z-shaped. The outer side of the pressure cap is connected to the guide rod, and the inner side of the pressure cap is connected to the scraper. The guide rod slides on the groove.

[0010] As an improvement to the above solution, an impact mechanism for enhancing the compaction effect is also included. The impact mechanism includes a sliding rod, an impact block, a second spring, and a limiting block. The upper front and rear sides of the pressure plate are slidably connected to the sliding rod, and the sliding rod is slidably connected to the ring claw. The sliding rod is slidably connected to the impact block, and the second spring is sleeved on the sliding rod. The two sides of the second spring are connected to the impact block and the sliding rod, respectively. The inner wall of the ring claw is connected to the front and rear sides of the limiting block. The limiting block is made of rubber, and the impact block is stuck on the limiting block.

[0011] As an improvement to the above solution, a positioning mechanism for locating the position of the tree trunk is also included. The positioning mechanism includes a bracket, a positioning plate, a limiting rod, a rotating rod, a slide block, and a third spring. The upper part of the rotating shaft is connected to the bracket, and the rear part of the bracket is connected to the positioning plate. The left and right sides of the rear part of the positioning plate are slidably connected to the limiting rods, which are located on the left and right sides of the tree trunk, respectively. The slide block is slidably connected to the positioning plate, and the left and right sides of the lower part of the slide block are rotatably connected to the rotating rods, which are rotatably connected to the limiting rods. The positioning plate is fitted with a third spring, and the two sides of the third spring are connected to the slide block and the positioning plate, respectively.

[0012] As an improvement to the above solution, a shrinkage mechanism for adapting to smaller tree trunks is also included. The shrinkage mechanism includes a shrinkage block, a fourth spring, and a shrinkage rod. The upper part of the pressure cap is slidably connected to the shrinkage rod, and a shrinkage block is connected to each shrinkage rod. The fourth spring is sleeved on each shrinkage rod, and the two sides of the fourth spring are connected to the shrinkage block and the pressure cap, respectively.

[0013] The beneficial effects of the present invention are: 1. The present invention pushes the surrounding soil to the bottom of the tree trunk by rotating the ring claw inward. The rotation of the ring claw inward drives the pressure rod to move backward. The backward movement of the pressure rod pushes the pressure cap downward to compact the soil, thereby completing the soil covering work of the tree trunk.

[0014] 2. By moving the cap downwards and rotating it back and forth, the scraper rotates back and forth to move the soil, making the soil around the tree trunk evenly distributed and preventing local collapse.

[0015] 3. After the pressure cap moves downward a certain distance, the impact block moves downward rapidly under the reset action of the second spring, generating an impact force on the pressure cap and improving the compaction effect of the pressure cap.

[0016] 4. Position the front of the tree trunk using the positioning plate, and limit the left and right sides of the tree trunk using the limiting rod, so that the tree trunk is in the center of the cover, which facilitates the subsequent covering work.

[0017] 5. By moving the shrinkage block inward, the soil in the center of the smaller tree trunk is compacted, thus achieving a better compaction effect and making it suitable for smaller tree trunks. Attached Figure Description

Detailed Implementation

[0032] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0033] Example 1

[0034] A seedling mulching and frost protection machine, referring to Figures 1-5 It includes a connecting rod 1, a bulldozing mechanism 3 and a compaction mechanism 4. The connecting rod 1 is located on the front side of the trunk 2. The connecting rod 1 is equipped with a bulldozing mechanism 3 and a compaction mechanism 4. The compaction mechanism 4 is used to compact the soil, and the bulldozing mechanism 3 is used to push the surrounding soil to the bottom of the trunk 2.

[0035] Reference Figure 3 The bulldozing mechanism 3 includes a ring claw 31, a rotating shaft 32, a hydraulic cylinder 33, a push plate 34, and a pull rod 35. The rear of the connecting rod 1 is connected to the rotating shaft 32, and two ring claws 31 are rotatably connected to the rotating shaft 32. The two ring claws 31 clamp each other and are used to push the soil to the bottom of the tree trunk 2. The rear of the connecting rod 1 is equipped with a hydraulic cylinder 33, and the extension rod of the hydraulic cylinder 33 is connected to the push plate 34. The left and right sides of the push plate 34 are rotatably connected to the pull rods 35, and the rear of the pull rods 35 are rotatably connected to the ring claws 31 on the same side.

[0036] Reference Figures 4-5 The compaction mechanism 4 includes a pressure rod 41, a first spring 42, a pressure cap 43, and a slider 44. The pressure cap 43 is slidably connected to both sides of the inner wall of the ring claw 31. The pressure caps 43 form a frustum shape after contacting each other. The pressure caps 43 are used to compact the soil at the bottom of the tree trunk 2. The slider 44 is slidably connected to each pressure cap 43. The first spring 42 is connected between the ring claw 31 and the slider 44 on the same side. The pressure rod 41 is slidably connected between the two ring claws 31. The pressure rod 41 contacts the pressure cap 43. The pressure rod 41 is used to push the pressure cap 43 to move downward. The front part of the ring claw 31 has a pressure groove, and the pressure rod 41 slides on the pressure groove.

[0037] In use, the connecting rod 1 is brought close to the bottom of the tree trunk 2, so that the annular claw 31 is located on the left and right sides of the tree trunk 2. Then, the hydraulic cylinder 33 is activated. The extension rod of the hydraulic cylinder 33 drives the push plate 34 to move backward. The backward movement of the push plate 34 drives the annular claw 31 to rotate inward through the pull rod 35. During the inward rotation of the annular claw 31, the pressure cap 43 is also rotated inward, pushing the soil around the tree trunk 2 towards the center. At the same time, the inward rotation of the annular claw 31 drives the pressure rod 41 to move backward. Since the pressure cap 43 is frustum-shaped, the backward movement of the pressure rod 41 pushes the pressure cap 43 downward. The downward movement of the pressure cap 43 drives the slider 44 downward, stretching the first spring 42. The pressure cap 43 then moves downward. The soil is compacted until the two annular claws 31 clamp together. At this point, the caps 43 come into contact with each other, thus covering the bottom of the tree trunk 2 with soil, achieving the effect of protecting the tree trunk 2 from the cold. After covering, the telescopic rod of the hydraulic cylinder 33 drives the push plate 34 to move forward. The push plate 34 drives the annular claws 31 to rotate outward and open through the pull rod 35. The rotation of the annular claws 31 to the outside drives the caps 43 to rotate outward. At the same time, the pressure rod 41 moves forward to reset, and the first spring 42 resets. Under the reset action of the first spring 42, the slider 44 and the caps 43 reset upward. Then, the remaining tree trunks 2 can be covered with soil in accordance with the above steps. After all the covering is completed, the hydraulic cylinder 33 is turned off.

[0038] Example 2

[0039] Based on Example 1, referring to Figures 6-7 It also includes a leveling mechanism 5, which is used to make the soil around the tree trunk 2 evenly distributed. The leveling mechanism 5 includes a guide rod 52 and a scraper 53. The inner side of the ring claw 31 is provided with a sliding groove 51, which is Z-shaped. The outer side of the pressure cover 43 is connected to the guide rod 52, which slides on the sliding groove 51. The inner side of the pressure cover 43 is connected to three scrapers 53, which are used to stir the soil at the bottom of the tree trunk 2.

[0040] Because the inner wall of the ring claw 31 has a groove 51, the pressure cap 43 moves downward and rotates back and forth through the guide rod 52. The rotation of the pressure cap 43 drives the scraper 53 to rotate back and forth. The scraper 53 moves the soil at the bottom of the trunk 2, so that the soil at the bottom of the trunk 2 is evenly distributed and avoids the collapse of some areas.

[0041] Reference Figures 8-9It also includes an impact mechanism 6, which is used to enhance the compaction effect. The impact mechanism 6 includes a slide rod 61, an impact block 62, a second spring 63, and a limiting block 64. The slide rod 61 is slidably connected to both the front and rear sides of the inner wall of the annular claw 31. The slide rod 61 is slidably connected to the pressure cap 43. The impact block 62 is slidably connected to the slide rod 61. The impact block 62 is used to impact the pressure cap 43. The second spring 63 is sleeved on the slide rod 61. The two sides of the second spring 63 are respectively connected to the impact block 62 and the slide rod 61. The limiting block 64 is connected to both the front and rear sides of the inner wall of the annular claw 31. The limiting block 64 is made of rubber. The impact block 62 is stuck on the limiting block 64.

[0042] Initially, the impact block 62 is stuck on the limiting block 64. When the pressure cap 43 moves downward, the second spring 63 is stretched, which in turn drives the sliding rod 61 to move downward. After the pressure cap 43 moves a certain distance, the limiting block 64, being made of rubber, deforms under certain pressure. At this point, the limiting block 64 no longer holds the impact block 62. Under the reset action of the second spring 63, the impact block 62 moves downward quickly, thus generating a certain impact force on the pressure cap 43, thereby enhancing the compaction effect on the soil. When the pressure cap 43 moves upward, it moves the impact block 62 above the limiting block 64 to complete the reset.

[0043] Reference Figures 10-11 It also includes a positioning mechanism 7, which is used to position the tree trunk 2. The positioning mechanism 7 includes a bracket 71, a positioning plate 72, a limiting rod 73, a rotating rod 74, a slide block 75, and a third spring 76. The upper part of the rotating shaft 32 is connected to the bracket 71, and the rear part of the bracket 71 is connected to the positioning plate 72. The slide block 75 is slidably connected to the positioning plate 72. The left and right sides of the lower part of the slide block 75 are rotatably connected to the rotating rod 74. The left and right sides of the rear part of the positioning plate 72 are slidably connected to the limiting rod 73. The limiting rod 73 is located on the left and right sides of the tree trunk 2 respectively. The limiting rod 73 is used to position the left and right sides of the tree trunk 2. The rotating rod 74 is rotatably connected to the limiting rod 73. The positioning plate 72 is fitted with a third spring 76. One end of the third spring 76 is connected to the slide block 75, and the other end is connected to the positioning plate 72.

[0044] Before covering the tree trunk 2 with soil, first pull the limiting rod 73 outward. The movement of the limiting rod 73 outward drives the sliding seat 75 to move backward through the rotating rod 74, compressing the third spring 76. Then move the device so that the limiting rod 73 is located on the left and right sides of the tree trunk 2 respectively, and the positioning plate 72 contacts the front of the tree trunk 2. Then release the limiting rod 73, and the third spring 76 returns to its original position. Under the action of the third spring 76, the sliding seat 75 returns to its original position forward. The forward movement of the sliding seat 75 drives the limiting rod 73 to move inward through the rotating rod 74 to position the tree trunk 2, so that the tree trunk 2 is located in the center of the cover 43, thereby improving the soil covering effect.

[0045] Reference Figures 12-13 It also includes a shrinking mechanism 8, which is used to adapt to smaller tree trunks 2. The shrinking mechanism 8 includes a shrinking block 81, a fourth spring 82 and a shrinking rod 83. Three shrinking rods 83 are slidably connected to the upper part of the pressure cover 43. Each shrinking rod 83 is connected to a shrinking block 81. The shrinking block 81 is used to compact the soil in the center of the smaller tree trunk 2. A fourth spring 82 is connected between the shrinking block 81 and the pressure cover 43. The fourth spring 82 is sleeved on the shrinking rod 83.

[0046] When covering a smaller tree trunk 2 with soil, as the cap 43 presses down, the shrink block 81 moves inward under the action of the fourth spring 82 to compact the soil in the center of the tree trunk 2, thereby achieving a better compaction effect and being suitable for smaller tree trunks 2.
