Description

Technical Field

[0001] This utility model belongs to the field of soil turning tools, and in particular relates to a soil turning device for planting. Background Technology

[0002] Turning the soil is a crucial step in agricultural production, significantly impacting plant growth and soil health. Turning breaks up soil compaction, increasing aeration and permeability, thus improving soil physical properties. This promotes root expansion and growth, enabling plants to better absorb water and nutrients. Turning also buries surface organic matter (such as fallen leaves and branches) into the soil, increasing organic matter content and fertility through decomposition. Furthermore, turning brings nutrients from deeper soil layers to the surface for plant use. It also disrupts the habitat of pests and diseases, reducing their occurrence. For example, turning exposes pathogens, insect eggs, and pupae to the air, killing them through wind, sun, or freezing temperatures, thus reducing the incidence of pests and diseases the following year. Turned soil also retains moisture better, especially when turned in autumn, allowing for the utilization of autumn and winter rainfall to provide sufficient water for spring crops. This is particularly important in areas with dry springs. Turning the soil also accelerates the soil maturation process, allowing minerals and organic matter in the soil to be converted into forms that plants can utilize more quickly. This helps improve soil fertility and water retention capacity, creating better conditions for crop growth. Turning the soil can bury weed seeds on the surface into deeper soil layers or bring weed seeds from deeper layers to the surface, thereby inhibiting weed growth. This is very effective in keeping farmland clean and reducing competition between weeds and crops for resources.

[0003] Tillage plays a crucial role in the planting process, not only helping to improve crop yield and quality but also enhancing the long-term health of the soil. Therefore, farmers should rationally schedule the timing and depth of tillage during the planting process to fully realize its positive effects.

[0004] Large machinery, such as rotary tillers, moldboard plows, disc plows, reversible plows, tracked ditching and fertilizing machines, and multi-functional tillers, are often used for tilling large areas of farmland. However, these large machines are limited and unsuitable for small areas of farmland. Tilling methods for small areas of farmland often use hoes, spades, and other similar tools. For example, the tiller disclosed in publication number CN209572434U includes a head, a shaft, and a handle. The head includes forks and a connecting body. The forks and the connecting body are connected by a fixed plate. A connecting plate is provided at the root of the forks, and a pedal is fixed to the connecting plate. The connecting body has a semi-ring structure and is connected to the fixed plate. One end of the shaft is equipped with a handle, and the other end of the shaft is connected to the connecting body. Although the technical solution achieves the function of turning over the soil in the planted land, it has been found in practice that when using the device to turn the soil, because the soil is often accompanied by fallen leaves, straw, plastic waste, etc., the fork teeth will continuously accumulate debris or clay, which will affect the normal use of the turner. It is necessary to clean the debris on the fork teeth frequently by hand, which is not conducive to the normal use of the turner. Utility Model Content

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] This utility model provides a soil-tilling device for planting, see reference. Figure 1 , Figure 2 and Figure 3The device includes a head 1 and a rod 2. The rod 2 has a grip 3 at one end away from the head 1. The head 1 includes a connecting plate 4. The connecting plate 4 has a groove 5 at one end away from the rod 2. A row of fork teeth 6 is provided along the length of the bottom of the groove 5. The fork teeth 6 are pointed at one end away from the connecting plate 4. The groove 5 also has a cleaning component 7 that moves along the length of the fork teeth 6. The cleaning component 7 includes a movable plate 71 located inside the groove 5. The movable plate 71 has a plurality of sleeves 72 that are fitted onto each fork tooth 6. The sleeves 72 have a coaxial annular blade 73 at one end away from the connecting plate 4.

[0029] The movable plate and sleeve can move along the length of the fork teeth, allowing the sleeve and the annular blade to move outside the fork teeth, thus removing debris from them. It should be noted that the maximum displacement of the annular blade exceeds the tip of the fork tooth 6, but the maximum displacement of the sleeve does not exceed the tip of the fork tooth 6.

[0030] Furthermore, as a specific implementation method, refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The rod portion 2 includes a tube body 21. Inside the tube body 21 is a pushing assembly 8 for moving the movable plate 71. The pushing assembly 8 includes a push rod 81 coaxially disposed inside the tube body 21. One end of the push rod 81 is connected to the movable plate 71 via a first connecting rod 83. An annular push cylinder 85 for pushing the push rod 81 is disposed on the outer side of the tube body 21 away from the connecting plate 4. A return spring 86 for restoring the movable plate 71 to its original position is also disposed between the push rod 81 and the interior of the tube body 21. By manually pushing the annular push cylinder, the push rod can be moved closer to the movable plate 71, compressing the return spring 86. This causes the first connecting rod and the movable plate to move along the length of the fork teeth, thereby moving the sleeve and the annular blade outside the fork teeth to remove debris. Afterwards, the return spring resets the movable plate back into the groove, facilitating the next removal of debris from the fork teeth.

[0031] Furthermore, as a specific implementation method, refer to Figure 1 and Figure 2 The end face of the connecting plate 4 near the rod 2 is connected to the tube 21 by a U-shaped connector 9. The two ends of the U-shaped connector 9 are located at the two ends of the length direction of the connecting plate 4, the middle of the lower end of the U-shaped connector 9 is connected to the end of the tube 21, and the end of the tube 21 extends to the inside of the U-shaped connector 9.

[0032] Furthermore, as a specific implementation method, refer to Figure 1 , Figure 2 and Figure 3 The connecting plate 4 has a guide cylinder 10 adapted to the first connecting rod 83 on one end face near the rod 2. The end of the first connecting rod 83 away from the push rod 81 is connected to the movable plate 71 via the guide cylinder 10. The guide cylinder 10 improves the stability of the first connecting rod 83 when it moves.

[0033] Several first connecting rods 83 are provided, and the ends of several first connecting rods 83 away from the movable plate 71 are connected to the end of the push rod 81 through second connecting plates 82. This further improves the stability of the first connecting rods 83 and the movable plate 71 during movement.

[0034] Furthermore, as a specific implementation method, refer to Figure 4 The tube body 21 has several rectangular openings 22 at one end away from the connecting plate 4. The length of each rectangular opening 22 is along the length of the tube body 21. A second connecting rod 84 is provided at one end of the push rod 81 away from the movable plate 71. The other end of the second connecting rod 84 is connected to the inner side of the annular push cylinder 85 via the rectangular openings 22. The presence of several second connecting rods 84 improves the stability of the annular push cylinder 85 during movement and prevents it from rotating around its axis. The length of the rectangular opening 22 is not less than the maximum displacement of the annular blade 73, meaning the maximum displacement of the annular push cylinder 85 is not less than the maximum displacement of the annular blade 73.

[0035] Furthermore, as a specific implementation method, refer to Figure 5 An annular groove 23 is coaxially provided on the inner side of the tube body 21 at the position of the rectangular opening 22. A reset spring 86 is provided in the annular groove 23. The end of the reset spring 86 away from the connecting plate 4 is in contact with the second connecting rod 84.

[0036] Furthermore, as a specific implementation method, refer to Figure 6 The connecting plate 4 has a pedal 11 vertically installed on one side along its length. In use, the side with the pedal faces the user, i.e., the inclined surface faces the user. The user steps on the pedal, first inserts the fork vertically into the soil, and then exerts force backward. Using the pedal as a fulcrum, the soil is turned up through the lever principle, saving time and effort.
