Technical Field

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

[0002] Tea leaves, commonly known as tea, generally include the leaves and buds of the tea plant. Tea contains catechins, cholesterol, caffeine, inositol, folic acid, and pantothenic acid, which are beneficial to health. Tea beverages are one of the world's three major beverages. Tea production requires the large-scale planting of tea trees, and the soil in the tea garden must be tilled before planting to ensure that the soil is loose and well-aerated.

[0003] In existing technologies, soil turning machines are usually used to turn the soil in tea gardens. However, the area turned by the turning plate of the soil turning machine is relatively fixed and it is not easy to expand the turning plate. In reality, the area of ​​tea gardens varies in size. When encountering a large tea garden, the staff needs to push the soil turning machine to perform multiple turning operations, which reduces the soil turning efficiency.

[0019] like Figure 1-5 As shown, the present invention proposes a soil turning machine for tea gardens, including a soil turning machine 1 and a main shaft 2. The main shaft 2 is rotatably installed at the output end of the soil turning machine 1. A secondary shaft 3 is respectively provided at both ends of the main shaft 2. A soil turning plate 4 is fixedly sleeved on the outer surface of the main shaft 2 and the secondary shaft 3. When the soil turning machine 1 is started, the main shaft 2 is driven to rotate, and then the soil turning plate 4 is driven to turn the soil.

[0020] In this embodiment, as Figure 2The end of the secondary shaft 3 is provided with a quick-release assembly that cooperates with the main shaft 2. The quick-release assembly includes two connecting rods 7, each fixed to the end of the secondary shaft 3. Connecting grooves 11 are provided at both ends of the main shaft 2, and the connecting rods 7 are inserted into the inner walls of the connecting grooves 11. Two rectangular grooves 8 are provided symmetrically on the surface of the connecting rods 7. A first spring 9 is fixed to the inner wall of the rectangular groove 8, and a protrusion 10 is fixed to the end of the first spring 9. Four rectangular through holes 12 are provided on the outer surface of the main shaft 2 corresponding to the protrusions 10, and the protrusions 10 are inserted into the inner walls of the rectangular through holes 12. (This is related to tea garden planting.) When the area is large, the area to be turned over each time can be increased by increasing the number of turning plates 4, thereby improving the turning efficiency. In actual operation, the connecting rod 7 on the sub-shaft 3 is inserted into the connecting groove 11 of the main shaft 2. During the insertion process, the protrusion 10 is squeezed. At this time, the protrusion 10 is located in the rectangular groove 8 and the protrusion 10 compresses the first spring 9. After the connecting rod 7 is fully inserted into the connecting groove 11, the protrusion 10 reaches the rectangular through hole 12. At this time, under the elastic force of the first spring 9, the protrusion 10 is inserted into the rectangular through hole 12, thereby limiting the connecting rod 7 and facilitating the disassembly and assembly of the sub-shaft 3.

[0021] Furthermore, such as Figure 2 and Figure 3 The outer surface of the main spindle 2 is provided with a protective component that cooperates with the quick-release assembly. The protective component includes four rectangular grooves 13 on the outer surface of the main spindle 2. The inner wall of the groove 13 is slidably connected to a slider 14. Sleeves 16 are slidably fitted at both ends of the main spindle 2. Two sliders 14 on one side are fixed to the inner wall of the sleeve 16. The protective component also includes a fixing rod 18 fixed to the inner wall of the groove 13. A second spring 17 is fitted on the outer surface of the fixing rod 18. One end of the second spring 17 is fixed to the surface of the slider 14, and the other end of the second spring 17 is fixed to the inner wall of the groove 13. After the sub-shaft 3 is connected, the sleeve 16 covers the rectangular through hole 12, thereby shielding and protecting the rectangular through hole 12. During this process, the elastic force of the second spring 17 keeps the slider 14 on one side of the groove 13, and then limits the sleeve 16 to avoid the influence of debris. When it is necessary to remove the sub-shaft 3, the sleeve 16 can be pulled to disengage it from the rectangular through hole 12.

[0022] It should be noted that two levers 15 are fixed on the outer surface of the sleeve 16, which facilitate the movement of the sleeve 16.

[0023] In this embodiment, as Figure 1 , Figure 4 and Figure 5The main guard plate 5 is fixed to the surface of the soil turner 1 and located around the soil turning plate 4. The main guard plate 5 is slidably connected to the two sides of the main guard plate 5. The top surface of the secondary guard plate 6 is provided with a fastening groove 20. Two fastening screws 19 are threaded through the surface of the main guard plate 5. The ends of the fastening screws 19 abut against the inner wall of the fastening groove 20. When the soil turner 1 turns the soil, the main guard plate 5 separates the soil brought out by the soil turning plate 4. After the secondary shaft 3 is installed, the secondary guard plate 6 is pulled out and the fastening screws 19 are rotated so that their ends abut against the inner wall of the fastening groove 20, thereby limiting the secondary guard plate 6 and expanding the protection range.

[0024] It is worth noting that a gripping hole 21 is provided at the edge of the surface of the secondary guard plate 6, which facilitates the pulling out of the secondary guard plate 6.

[0025] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
