Description

Technical Field

[0001] This utility model relates to the field of soil-building devices, and in particular to a soil-building device for crop planting. Background Technology

[0002] In modern agricultural production, the requirements for soil quality in crop hilling operations are constantly increasing. High-quality hilling can not only stabilize plants and improve the root growth environment, but also significantly improve crop yield and quality. For example, spinach is a shallow-rooted leafy vegetable that is sensitive to soil resistance during its growth. Large clods of soil or hard soil layers can hinder root extension and affect water and nutrient absorption. Existing crop hilling devices are equipped with simple sieves to perform preliminary soil screening through the sieve mesh size.

[0003] A potato hilling device, with publication number CN212034806U, includes rollers, a connecting frame, a fixed base plate, a water tank, a water inlet, a fixed plate, a connecting pipe, a nozzle, a connecting plate, a guide pipe, a water pump, a battery, a housing, a pusher, a swing arm, a connecting rod, and a hilling shovel. This utility model has a simple structure, featuring a housing, water tank, nozzle, water pump, and battery. The water pump sprays water stored in the tank through the nozzle to irrigate the potato crop. The rollers, fixed base plate, pusher, swing arm, connecting rod, and hilling shovel enable the hilling device to move forward and the swing arm to operate the hilling shovel, thus hilling the potatoes. The entire device has a compact structure, increasing its practicality.

[0004] Regarding the aforementioned technologies, the existing soil-building devices have the following drawbacks: the static screen is prone to soil clogging of the screen holes, affecting the screening efficiency and causing a large amount of unqualified soil to be directly used for soil building, thus reducing the quality of soil building. Therefore, this utility model provides a soil-building device for crop planting. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1: Reference Figure 1-4The illustrated crop planting and soil preparation device includes a processing chamber 1, which serves as the core load-bearing component, used to contain soil and provide space for subsequent screening, crushing, and other operations. A screening assembly is installed inside the processing chamber 1, including a torsion spring 17 installed on the inner side wall of the processing chamber 1. The torsion spring 17 can return to its original position after the filter plate 18 is pushed upwards by force, providing power for the up-and-down swaying of the filter plate 18. One end of the torsion spring 17 is fixedly connected to the filter plate 18, which is inclined. This inclined design facilitates the sliding of soil along the surface of the filter plate 18 under its own weight, and also allows the sieved soil to be concentrated and discharged in a specific direction. The filter plate 18 is used to screen the soil, removing soil particles of suitable size and intercepting large, unsuitable soil particles. A fixing plate 19 is fixedly connected to the inner side wall of the processing chamber 1, used to fix an electric push rod 15, ensuring the stability of the electric push rod 15 during operation. The top of the fixing plate 19 is fixedly connected to the electric push rod 15, which pushes the spring through extension and contraction. The elastic block 14 contacts or separates from the filter plate 18, thereby controlling the lifting and swaying amplitude of the filter plate 18; the output end of the electric push rod 15 is fixedly connected to the elastic block 14. When the elastic block 14 abuts against the filter plate 18, it can play a buffering role to avoid hard collision damage to the filter plate 18. At the same time, when the filter plate 18 falls, it collides with the elastic block 14, causing the filter plate 18 to sway up and down, enhancing the screening effect; the top of the elastic block 14 is in contact with the bottom of the filter plate 18; the inside of the processing chamber 1 is equipped with a crushing component, which is used to crush the unqualified large particles of soil that have been screened, so that they reach a suitable particle size; the crushing component includes a pair of connecting rods 8 rotatably connected inside the processing chamber 1. The connecting rods 8 all penetrate the processing chamber 1. The connecting rods 8 serve as power transmission components, transmitting external power to the crushing rods 11, and also supporting the crushing rods 11; the side walls of the connecting rods 8 are fixedly connected to the crushing rods 11. The crushing rods 11, through mutual meshing, squeeze and shear the large particles of soil entering the crushing component, crushing them into smaller particles for further screening.

[0025] Example 2: Reference Figure 1-4Based on the same concept as in Embodiment 1 above, this embodiment further proposes that gears 10 are fixedly connected to the side walls of the connecting rods 8. The gears 10, as transmission components, transmit the rotational power of one connecting rod 8 to the other through their meshing tooth structure, achieving synchronous counter-rotation of the two crushing rods 11. A pair of meshing gears 10 are located on the outside of the processing chamber 1. This placement on the outside of the processing chamber 1 facilitates maintenance and repair of the gears 10, while preventing them from contacting the soil inside the processing chamber 1 during transmission, thus reducing wear and malfunctions. A support frame 2 is fixedly connected to the side wall of the processing chamber 1. The support frame 2 supports and fixes the motor 9, ensuring the operation of the motor 9. To ensure stability and avoid affecting transmission efficiency due to vibration, a motor 9 is fixedly connected to the top of the support frame 2. The motor 9 serves as a power source, outputting rotational power to drive the connecting rod 8 to rotate, providing operating power for the crushing assembly. The output end of the motor 9 is fixedly connected to one end of one of the connecting rods 8. A guide rod 13 is fixedly connected to the inner side wall of the processing chamber 1. The guide rod 13 provides guidance for the up-and-down movement of the filter plate 18, ensuring that the filter plate 18 slides stably along a straight line and preventing deviation from affecting the screening effect. The filter plate 18 slides along the side wall of the guide rod 13. A guide plate 12 is provided inside the processing chamber 1. The guide plate 12 is used to guide the soil screened off from the filter plate 18, allowing it to flow smoothly to the bottom of the processing chamber 1. A guide block 16 is installed to prevent soil from accumulating in other areas inside the treatment chamber 1. The bottom of the treatment chamber 1 is fixedly connected to the guide block 16, which is sloped. The sloped design utilizes gravity to allow the screened soil to be quickly discharged from the treatment chamber 1 along the guide block 16, improving soil discharge efficiency. A first inlet 3 is located at the top of the treatment chamber 1, used to input unscreened soil from the collection box 5 into the treatment chamber 1 for crushing and further processing. A second inlet 4 is located at the top of the treatment chamber 1, used to input the original planting soil to be processed into the treatment chamber 1 for initial screening. A collection box 5 is installed on the side wall of the treatment chamber 1 for temporarily storing soil from the filter plate. The unqualified large-particle soil selected on the 18th is convenient for subsequent centralized treatment; the side wall of the collection box 5 is fixedly connected to the connecting plate 6, which provides a structural foundation for the connection between the collection box 5 and the treatment chamber 1; the outside of the connecting plate 6 is provided with bolts 7, which are used to fasten the connecting plate 6 to the treatment chamber 1, so that the collection box 5 can be stably installed on the side wall of the treatment chamber 1, and at the same time, it is easy to disassemble and clean; the side wall of the connecting plate 6 and the side wall of the treatment chamber 1 are both provided with connecting grooves that are compatible with the bolts 7. The connecting grooves ensure that the bolts 7 can be accurately inserted and tightened, ensuring the firmness of the connection. This application is provided with a controller and a power supply. The controller is used to control electrical appliances (such as motors and electric push rods), and the power supply is used to provide power.

[0026] The working principle of this device is as follows: When using this device, the planting soil is first put into the processing chamber 1 through the second inlet 3. The electric push rod 15 extends, and the elastic block 14 abuts against the filter plate 18, causing the filter plate 18 to be raised to a certain height along the guide rod 13. The electric push rod 15 retracts, and the filter plate 18 will be reset under the action of the torsion spring 17. During the fall, it collides with the elastic block 14, and the filter plate 18 will shake up and down to a certain extent. The planting soil with the appropriate particle size that falls on the filter plate 18 falls onto the guide block 16 and is discharged from the processing chamber 1 by its own gravity. The planting soil with the wrong particle size on the filter plate 18 will fall into the collection box 5 from the upper outlet. The planting soil in the collection box 5 is put into the first inlet 4. The motor 9 is started, and the planting soil is crushed by the meshing between the crushing rods 11 and falls onto the filter plate 18 for screening again.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
