Description

Technical Field

[0001] The present application relates to the technical field of soil loosening devices, and more specifically, to a soil loosening device for agricultural planting. Background Art

[0002] Agricultural seeds, such as garlic and corn, need to meet the prerequisites for normal growth and germination of certain moisture, suitable temperature and sufficient air environment. Therefore, before sowing agricultural seeds, for small plots of farmland, farmers need to use portable tillage shovels to turn over and loosen the farmland in advance to increase the porosity of soil particles and ensure normal seed respiration. The existing public technology number CN219459690U proposes a loosening device, which can fully crush the soil and ensure the loosening effect. In view of the above-mentioned related technologies, the utility model inventor believes that the following defects still exist: the loosening device in the comparative literature uses the sharp spikes at the bottom of the pressure plate to puncture the turned-out soil. Although it can solve the crushing problem of hard soil to a certain extent, the moist soil at the bottom cannot be crushed and still has a block structure after turning it out. In addition, the overall loosening device is generally not portable and needs to be carried on the shoulder or held, which is labor-intensive. In view of this, we propose a loosening device for agricultural planting. Utility Model Content

[0003] 1. Technical problems to be solved

[0004] The purpose of the present application is to provide a soil loosening device for agricultural planting, which solves the problem that the soil loosening device in the comparative literature in the above-mentioned background technology uses the spikes at the bottom of the pressure plate to puncture the turned-out soil during use.

In addition, the overall soil loosening device is generally not portable and needs to be carried by shoulders or held, which has high labor intensity. The soil loosening device can limit the installation position of the Y-shaped arm, so that the bottom frame can be easily pushed and moved along the farmland through four rollers, and the portability is strong. When loosening the soil is needed, the limiting structure of the Y-shaped arm is removed, and the pedal frame is pressed by the foot to insert the soil-breaking teeth into the ground. Then the Y-shaped arm is rotated as a lever with the rotating shaft as the axis to turn out the broken soil, and the soil-breaking teeth and rake teeth are used to form a shearing effect, so that the turned-out soil blocks are sheared and processed, solving the problem that traditional soil turners can only turn out blocky soil, and achieving the purpose of turning out soil fragments and loosening the soil, with a highly practical technical effect.

[0022] The present application is further described in detail below with reference to the accompanying drawings.

[0023] Reference Figures 1 to 3, the embodiment of the present application provides a soil loosening device for agricultural planting, comprising: a bottom frame 1, four rollers 11 are installed on the bottom frame 1 through an axis, a plurality of rake teeth 2, two cross guides 4 and a support plate 3 are fixed on the bottom frame 1, a cross block 42 is slidably installed in the cross guide 4, a return spring 43 is fixedly connected between the cross block 42 and the cross guide 4, a soil loosener 5 is installed between the cross blocks 42, the soil loosener 5 includes a Y-shaped arm 51, a pedal frame 53 is fixedly welded to the bottom end of the Y-shaped arm 51, a rotating shaft 54 ​​is fixed on both sides of the pedal frame 53, the rotating shaft 54 ​​is rotatably connected to a cross block 42 respectively, a plurality of soil breaking teeth 55 are welded and fixed on the bottom surface of the pedal frame 53, and a rake tooth 2 is arranged between two adjacent soil breaking teeth 55. The soil loosening device is Four rollers 11 are rotatably installed on the bottom frame 1, so that the Y-shaped arm 51 can be conveniently held manually and pushed along the farmland to improve portability. When loosening the soil is needed, the foot presses the pedal frame 53, so that the two rotating shafts 54 of the Y-shaped arm 51 drive the cross block 42 to slide downward along the corresponding cross guide rail 4, so that the soil-breaking teeth 55 at the bottom end of the Y-shaped arm 51 are inserted into the ground. Since the rotating shaft 54 ​​is rotatably connected to the cross block 42, the support plate 3 fixedly connected to the bottom frame 1 can achieve stable support processing in the lever principle, and then the Y-shaped arm 51 can be rotated along the axis of the rotating shaft 54 ​​to turn the soil upward. Since a rake tooth 2 is set between the two soil-breaking teeth 55, the soil-breaking teeth 55 and the rake teeth 2 form a shearing effect, which can make the soil blocks turned upward be sheared and processed to achieve the purpose of loosening the soil.

[0024] Reference Figure 1 and Figure 3 The bottom frame 1 is a rectangular frame structure, and the four rollers 11 are distributed in a rectangular structure. The bottom frame 1 can achieve rolling displacement by rotating the four rollers 11, which is convenient for pushing and moving.

[0025] Reference Figure 1 and Figure 3 The rake teeth 2 are fixed on the inner wall of the bottom frame 1, the support plate 3 is inclined and fixed on the outer surface of the bottom frame 1, and a plurality of strip grooves 31 are opened on the support plate 3. When the soil-breaking teeth 55 are inserted into the ground and the soil needs to be turned out, the rotating shaft 54 ​​of the Y-shaped arm 51 is the fulcrum of the lever, the bottom frame 1 and the support plate 3 are supported by the ground, and the cross block 42 connected by the return spring 43 on the cross guide rail 4 is rotated to connect the rotating shaft 54, forming a lever principle, which can make soil turning more easily.

[0026] Reference Figure 1 and Figure 3, screw holes 41 are provided at the upper ends of the cross guide rails 4, and L-shaped blocks 45 are fixed on the cross blocks 42. Screw rods 46 are threadedly installed on the L-shaped blocks 45, and screw rods 46 are threadedly installed in the screw holes 41. When it is necessary to push and move the entire device, under the action of the return spring 43, the Y-shaped arm 51 drives the pedal frame 53 and the earth-breaking tooth 55 to a position above the ground, and then the screw rods 46 are threadedly installed in the screw holes 41, so that the Y-shaped arm 51 and the cross guide rail 4 are stably limited.

[0027] Reference Figure 1 and Figure 2 A handle 52 is sleeved on the upper end of the Y-shaped arm 51, and a screw is threadedly connected between the Y-shaped arm 51 and the handle 52. The upper end of the Y-shaped arm 51 can be conveniently held and used by installing the handle 52.

[0028] Working principle: The loosening device is provided with four rollers 11 rotatably mounted on the bottom frame 1. When the entire device needs to be moved, the Y-shaped arm 51 drives the pedal frame 53 and the soil-breaking teeth 55 to move to a position above the ground under the action of the return spring 43. Then, the screw 46 is threadedly installed in the screw hole 41, so that the Y-shaped arm 51 and the cross guide 4 are stably limited. The Y-shaped arm 51 can be conveniently manually grasped and moved along the farmland, thereby improving portability. When loosening the soil is required, the foot presses the pedal frame 53, so that the two rotating shafts 54 of the Y-shaped arm 51 are moved. The cross block 42 is driven to slide downward along the corresponding cross guide rail 4, so that the soil-breaking teeth 55 at the bottom end of the Y-shaped arm 51 are inserted into the ground. Since the rotating shaft 54 ​​is rotatably connected to the cross block 42, the support plate 3 fixedly connected to the bottom frame 1 can realize the stable support processing in the lever principle, and then the Y-shaped arm 51 can be rotated along the axis of the rotating shaft 54 ​​to turn the soil upward. Since a rake tooth 2 is arranged between the two soil-breaking teeth 55, a shearing effect is formed by the soil-breaking teeth 55 and the rake teeth 2, which can make the soil blocks turned upward be sheared and processed, thereby achieving the purpose of loosening the soil.
