Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, specifically to a soil loosening machine for agricultural planting. Background Technology

[0002] Agriculture is an industry that utilizes the growth and development patterns of plants and animals to obtain products through artificial cultivation. Agriculture belongs to the primary sector, and the science that studies agriculture is agronomy. The objects of agricultural labor are living organisms such as plants and animals, and the products obtained come from these organisms themselves, such as silk and musk. Agriculture is a fundamental industry that supports national economic construction and development.

[0003] Patent CN207766803U discloses an agricultural soil loosening machine, which includes a ditching plow support frame, a gasoline engine mounted on top of the ditching plow support frame, a power connection plate at the connection point between the ditching plow support frame and the gasoline engine, and two handles at one end of the gasoline engine. The device makes cleaning the mudguards easier and saves time by providing scrapers on the mudguards and brushes at the bottom of the scrapers. The grip is made more secure by providing finger sleeves at one end of the handle, which can effectively prevent the hand from slipping off.

[0004] However, the existing device requires the operator to directly hold the handle to control the loosening blades at the bottom of the furrowing plow frame, and the machine lacks any mechanism for adjusting the loosening depth. Therefore, the loosening depth relies entirely on the handle, which varies depending on the planting depth requirements. Relying solely on the operator's experience makes it difficult to ensure the loosening depth meets the planting needs, thus affecting subsequent agricultural planting. Therefore, a new agricultural loosening machine is proposed to address the problem of existing machines' inability to accurately control the loosening depth according to planting requirements. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the shortcomings of the existing technology, this utility model provides a soil loosening machine for agricultural planting, which solves the above-mentioned problems.

[0010] Preferably, the hydraulic telescopic rod passes through the main body of the ripper and is fixedly connected to the lifting seat. When the top of the lifting seat is in contact with the main body of the ripper, the zero mark of the scale is flush with the top surface of the main body of the ripper.

[0011] Preferably, the soil loosening mechanism includes symmetrical U-shaped soil loosening frames fixedly connected to the bottom of the lifting seat. The inner cavity of the U-shaped soil loosening frame is rotatably provided with a rotating shaft. The outer ring of the rotating shaft is fixedly connected with a rotary tiller blade assembly. The blades on the rotary tiller blade assemblies in the two U-shaped soil loosening frames are staggered. When the top of the lifting seat is in contact with the main body of the soil loosening machine, the lowest position of the blades on the rotary tiller blade assembly is flush with the bottom of the roller.

[0015] (III) Beneficial Effects

[0016] 1. This agricultural soil loosening machine moves the main body of the soil loosening machine to the location where soil loosening is needed using a push handle and rollers. While moving, the hydraulic telescopic rod drives the lifting seat and the soil loosening mechanism to move downwards. The limit plate, which is fixedly connected to the lifting seat, improves the stability of the downward movement of the lifting seat. At the same time, the downward movement distance of the soil loosening mechanism can be precisely controlled by the scale, so as to accurately control the soil loosening depth. This solves the problem that existing soil loosening machines are unable to accurately control the soil loosening depth according to planting needs.

[0017] 2. During the loosening process of this agricultural soil loosening machine, the soil loosened by the rotary tiller blades will move towards the splash guard. At the same time, with the help of the fixing block and the limiting shaft, the splash guard is in a rotatable state. This ensures that even if there are protrusions on the ground due to loosening, the splash guard will rotate accordingly and still have a protective effect, preventing soil clods from splashing and causing injury to personnel, thus improving the protective effect of this agricultural soil loosening machine.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Example: Please refer to Figure 1-4 An agricultural soil loosening machine includes a soil loosening machine body 1, a push handle 2 fixedly connected to the top of the soil loosening machine body 1, four rollers 3 at the bottom of the soil loosening machine body 1, a lifting seat 4 at the bottom of the soil loosening machine body 1, two limiting plates 5 symmetrically arranged on the top of the soil loosening machine body 1, a scale 6 at one end of the limiting plate 5, a hydraulic telescopic rod 7 at the top of the soil loosening machine body 1, two symmetrical soil loosening mechanisms 8 at the bottom of the lifting seat 4, and a splash protection mechanism 9 at the bottom of the soil loosening machine body 1.

[0025] Furthermore, the limiting plate 5 penetrates the main body 1 of the soil tiller and the two are slidably connected, while the limiting plate 5 is fixedly connected to the lifting seat 4.

[0026] Furthermore, the hydraulic telescopic rod 7 penetrates the main body 1 of the ripper and is fixedly connected to the lifting seat 4. When the top of the lifting seat 4 is in contact with the main body 1 of the ripper, the zero mark of the scale 6 is flush with the top surface of the main body 1 of the ripper. The hydraulic telescopic rod 7 drives the lifting seat 4 and the ripper mechanism 8 to move down. The limiting plate 5 fixedly connected to the lifting seat 4 improves the stability of the downward movement of the lifting seat 4. At the same time, the scale 6 is used to precisely control the downward movement distance of the ripper mechanism 8, so as to accurately control the ripper depth.

[0027] Furthermore, the soil loosening mechanism 8 includes a U-shaped soil loosening frame 801 symmetrically and fixedly connected to the bottom of the lifting seat 4. The inner cavity of the U-shaped soil loosening frame 801 is rotatably provided with a rotating shaft 802. The outer ring of the rotating shaft 802 is fixedly connected with a rotary tiller blade assembly 803. The blades on the rotary tiller blade assembly 803 in the two U-shaped soil loosening frames 801 are staggered. When the top of the lifting seat 4 is in contact with the main body 1 of the soil loosening machine, the lowest position of the blades on the rotary tiller blade assembly 803 is flush with the bottom of the roller 3.

[0028] Furthermore, a motor 804 is fixedly connected to one side of the U-shaped soil loosening frame 801, and the motor 804 is fixedly connected to the rotating shaft 802. A sprocket 805 is provided on the other side of both U-shaped soil loosening frames 801, and the sprocket 805 is connected to the rotating shaft 802. The two sprockets 805 are connected by a chain 806.

[0029] Furthermore, the splash guard mechanism 9 includes two symmetrical and fixedly connected fixing blocks 901 at the bottom of the tiller body 1. A splash guard 902 is provided between the fixing blocks 901. The splash guard 902 is rotatably mounted at the bottom of the tiller body 1 by means of a limiting shaft 903. During the loosening process, the soil loosened by the rotary tillage blade assembly 803 will move towards the splash guard 902. At the same time, in conjunction with the fixing blocks 901 and the limiting shaft 903, the splash guard 902 is in a rotatable state, thereby ensuring that even if there are protrusions on the ground due to loosening, the splash guard 902 will rotate accordingly and still have a protective effect, preventing soil clods from splashing and causing injury to personnel, thus improving the protective effect of this agricultural planting tiller.

[0030] Furthermore, a placement trough 10 is provided on one side of the main body 1 of the soil loosening machine. A placement box 11 is slidably arranged in the inner cavity of the placement trough 10. Tools needed for the soil loosening process or seeds to be sown later can be placed in the placement box 11 in the placement trough 10, making it convenient to retrieve and use the tools later. If seeds are put in, sowing can be carried out at the same time as loosening the soil, which improves the functionality of this agricultural soil loosening machine.

[0031] Working principle: When using this agricultural soil loosening machine, the main body 1 of the loosening machine is moved to the location where soil needs to be loosened using the push handle 2 and rollers 3. While moving, the hydraulic telescopic rod 7 drives the lifting seat 4 and the loosening mechanism 8 to move down. The limiting plate 5, which is fixedly connected to the lifting seat 4, improves the stability of the lifting seat 4's downward movement. At the same time, the scale 6 precisely controls the downward movement distance of the loosening mechanism 8, thus accurately controlling the loosening depth. This solves the problem that existing soil loosening machines cannot accurately control the loosening depth according to planting needs. When moving the loosening machine and lowering the loosening mechanism 8, the motor 804 is turned on to rotate. With the help of the sprocket 805 and chain 806, the rotary tiller blade assembly 803 is rotated, which gradually enters the soil. With the staggered loosening blades on the rotary tiller blade assembly 803 in the two sets of U-shaped loosening frames 801, the purpose of loosening the soil is achieved, ensuring the quality of loosening while accurately controlling the loosening depth.
