Description

Technical Field

[0001] This invention relates to the field of soil improvement technology, and more specifically to a tillage device for improving compacted soil. Background Technology

[0002] Soil compaction is a significant manifestation of soil degradation, particularly subsoil compaction. As plant roots extend downwards, soil compaction severely hinders water absorption during the later stages of plant growth, especially under conditions of low rainfall and high evaporation. Drought can limit plant growth and yield formation.

[0003] Currently, the most common method for addressing soil compaction is deep tillage. This involves digging deep into the soil and tilling the land when planting seeds, turning over the deeper layers of soil and covering them with the shallower layers so that the seeds can lie deep in the soil and receive more nutrients. However, the effects of deep tillage are relatively short-lived and have high energy and time costs. Although deep tillage has alleviated soil compaction, it has also destroyed the topsoil cover that has been developed over many years of no-till management and increased the risk of soil erosion and topsoil compaction. Summary of the Invention

Detailed Implementation

[0022] Next, we will combine the appendix Figure 1-7 A specific embodiment of the present invention will be described in detail below.

[0023] A tillage device for improving compacted soil includes symmetrically arranged tracks 1. A drive wheel 2 and two driven wheels 3 are provided within the tracks 1. The drive wheel 2 and the driven wheels 3 are geared to the tracks 1. A mounting plate 4 is fixed between the two tracks 1. The upper end of the mounting plate 4 has a flange that covers the tracks 1. A drive motor 5 is fixed inside the mounting plate 4. A main gear is fixed at the output end of the drive motor 5. A driven gear is provided on the transmission shaft 6 inside the drive wheel 2. The driven gear meshes with the main gear. That is, by starting the drive motor 5, the gear rotates, causing the driven gear to rotate, which in turn causes the drive wheel 2 to rotate, thereby moving the tracks 1 forward and subsequently causing the driven wheels 3 to rotate.

[0024] The driving wheel 2 rotates, thereby driving the track 1 to move forward, which in turn causes the driven wheel 3 to rotate. This is existing technology and will not be elaborated on here.

[0025] A soil-turning device 7 is provided at the front end of the two tracks 1, which is used to shovel up the compacted soil; a crushing device 8 is provided at the upper end of the mounting plate 4, which is used to crush the shoveled soil; a fertilization device 9 is provided between the crushing device 8 and the soil-turning device 7, which is used to sprinkle nutrient base solution on the shoveled soil.

[0026] This involves shoveling up the compacted soil clods, spraying them with a nutrient-based liquid, and then covering the nutrient-based liquid with the broken soil, thereby fundamentally improving the nutritional structure of the compacted soil clods.

[0027] like Figure 2 As shown, the soil turning device 7 includes a flat plate 71 fixedly connected to the mounting plate 4. A transition plate 72 is fixedly provided at the front end of the flat plate 71. A plurality of shovel teeth 73 are fixedly provided at the front end of the transition plate 72. Sealing plates are also provided on both sides of the transition plate 72. That is, the shovel teeth 73 are used to pass the plated block through the transition plate 72 and into the flat plate 71.

[0028] like Figure 1 As shown, the crushing device 8 includes a base plate 81 fixedly connected to the inner side of the mounting plate 4. The base plate 81 is aligned with or located below the plate 71. Four mounting columns 82 are fixedly provided on the upper end of the base plate 81. A U-shaped groove 83 is provided in the middle of each mounting column 82. A sliding rod 84 is slidably connected inside the U-shaped groove 83. A horizontal plate 85 is fixed between two sliding rods 84. A plurality of evenly arranged crushing blocks 86 are fixed at the lower end of the horizontal plate 85. Two parallel crushing blocks 86 are provided on both sides of the horizontal plate 85. A crank 87 is provided, one end of which is connected to a slide rod 84 that passes through the U-shaped groove 83, and the other end is connected to a protrusion on the upper end of the driven wheel 3; that is, when the driven wheel 3 rotates, the horizontal plate 85 moves downward due to the action of the crank 87; breaking up the slabs on the base plate 81; correspondingly, the base plate 81 is provided with an arc-shaped groove, and multiple through holes are evenly provided inside the groove; that is, the broken slabs fall onto the turned-up soil through the through holes.

[0029] like Figure 3-4As shown, the fertilization device 9 includes symmetrically arranged storage tanks 91, which are used to store nutrient base solution for improving soil. A connecting pipe 92 is provided at the lower end of the storage tank 91, and the connecting pipe 92 communicates with the storage tank 91. The connecting pipe 92 is fixedly connected to the slide rod 84 via a first connecting plate 93. A notch is provided at the lower end of the connecting pipe 92, and a sealing plate 94 is provided at the upper end of the notch. The diameter of the sealing plate 94 is larger than the diameter of the notch. A connecting column 95 is fixedly provided at the lower end of the sealing plate 94. That is, by raising the connecting column 95, the notch is opened, and the nutrient base solution inside the storage tank 91 can flow out. To achieve this, the following measures are taken to raise the connecting column 95: a connecting block 96 is fixedly provided at the lower end of the connecting pipe 92, and the connecting block 96 is connected to the slide cylinder 98 via a first spring 97. A support column 910 is fixedly provided inside the slide cylinder 98 via a support frame 99. The support column 910 is fixedly connected to the connecting column 95. A feed pipe 911 is provided at the lower end of the slide cylinder 98, and the upper end of the feed pipe 911 is fixedly connected to the lower end of the slide cylinder 98. That is, when the slide rod 84 descends, it drives the connecting pipe 92 to move downward, thereby causing the connecting block 96 to compress the first spring 97, and then causing the connecting column 95 to move upward relative to the connecting pipe 92, thereby creating a gap between the sealing plate 94 and the notch, and the nutrient base liquid flows into the feed pipe 911 from the notch. The lower end of the feed pipe 911 is connected to the through pipe 913 through the guide pipe 912. The through pipe 913 is located below the mounting plate 4, and the upper end of the guide pipe 912 crosses the track 1, and the lower end passes through the track 1. Multiple normally open nozzles 914 are evenly arranged below the through pipe 913. The nutrient base liquid is sprayed onto the soil that has just been turned over under the compacted block through the nozzles 914.

[0030] like Figure 5-6 As shown: In this embodiment, the sliding rod 84 on the left is fixedly connected to the second connecting plate 10. The front end of the second connecting plate 10 is fixedly provided with a fixing plate 11, and a plurality of drilling devices 12 are fixedly provided on the fixing plate 11. The drilling device 12 includes a cone block 121 fixedly connected to the fixing plate 11. That is, by moving the sliding rod 84 on the left downward, the cone block 121 moves downward, thereby drilling holes in the soil covering the nutrient base solution, and then the plant seeds are put into the holes.

[0031] like Figure 6As shown, the applicant has found that after drilling, seeds still need to be manually placed into the holes, which increases the labor intensity of farmers. Therefore, this application addresses this issue with the following technical solution: A storage box 123 is connected to the upper end of the cone block 121 via a second spring 122. The storage box 123 is used to hold seeds and is fixedly connected to the fixing plate 11 via a protective sleeve. Feeding pipes 124 are provided on both sides of the storage box 123. A trapezoidal platform 132 is provided inside the storage box 123 to facilitate seed entry into the feeding pipes 124 on both sides. Two through holes 125 are provided inside the cone block 121. The part is provided with a fixing rod 126. One end of the fixing rod 126 passes through the second spring 122 and is fixedly connected to the bottom of the storage box 123. The other end is fixedly connected to the push block 127. There are connecting holes 128 on both sides of the cone block 121. The connecting holes 128 connect the through hole 125 and the conveying pipe 124. There are grooves 129 on one side of the two through holes 125. The upper end of the groove 129 is hinged to the inclined support plate 130. A third spring 131 is provided between the support plate 130 and the inner wall of the groove 129. One end of the third spring 131 is fixedly connected to the rear end of the support plate 130, and the other end is fixedly connected to the inside of the groove 129.

[0032] It should be noted that when the second spring 122 is in its natural state, the outlet at the lower end of the conveying pipe 12 is connected to the through hole 125 through the connecting hole 128. The seeds enter the through hole 125 and are located in the space formed by the support plate 130 and the push block 127. That is, when the sliding rod 84 moves downward, the cone block 121 contacts the soil first and then squeezes the second spring 122, causing the fixing rod 126 to move downward. The push block 127 moves downward, and since a third spring 131 is provided between the support plate 130 and the inner wall of the groove 129, the support plate 130 contracts, and the seeds leak into the hole, completing the seed sowing.

[0033] The applicant needs to emphasize that the cone 12 is made of metal. When the cone 12 moves downward, soil will enter the through hole 125. Since the cone 121 is made of metal, there will be no soil clogging the through hole 125. Of course, if there is soil clogging, it will not affect the next use due to the action of the push block 127. Secondly, since the soil is compacted, the soil hardness is relatively strong. And since the cone 12 has been drilled, no soil will enter at the height of the support plate 130, that is, there will be no soil damaging the support plate 130 and the third spring 131.

[0034] like Figure 7As shown, in this embodiment, a soil covering device 13 is provided at the rear end of the drilling device 12. The soil covering device 13 includes a support plate A133 fixed to the rear end of the mounting plate 4. A soil covering plate 134 is hinged below the support plate A133. The soil covering plate 134 covers the hole drilled by the cone block 121. This technology is prior art and will not be described in detail here.

[0035] Compared with the prior art, the present invention has a soil turning device and a fertilization device between the crushing device and the soil turning device. The compacted soil clods are shoveled up, then sprayed with nutrient base liquid, and then covered with nutrient base liquid through the crushed soil, which fundamentally improves the nutrient structure of the compacted soil clods. It is simple to operate and highly practical.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
