Description

Technical Field

[0001] This utility model relates to the technical field of agricultural machinery, specifically to a solid soil conditioner spreader. Background Technology

[0002] Soil, as the foundation of agricultural production, directly impacts crop growth and yield. Soil quality can be measured by its physical, chemical, and biological characteristics, including soil structure, water retention capacity, nutrient content, and microbial activity. Under natural conditions, soil can degrade due to long-term agricultural activities, environmental pollution, or other natural factors, leading to disordered soil structure, nutrient imbalances, or decreased microbial activity. These problems severely restrict the sustainability of agricultural production and crop quality.

[0003] For landscaping, the current practice is mainly carried out in and around cities. Construction waste is often mixed in with the soil, and the application of fertilizers, pesticides, and insecticides leads to soil degradation, or the soil itself is infertile. If lawns and trees are planted directly on the soil, it will affect their survival rate and healthy growth. In the existing technology, the technical solutions generally adopted to address the above problems are: (1) covering the original land with good soil from other places; (2) using natural amendments, such as zeolite, bentonite, fly ash, crop straw, legume green manure, and livestock and poultry manure; (3) artificial synthetic amendments; (4) natural-synthetic copolymer amendments.

[0004] Application research has revealed that the current method of applying solid soil conditioners involves first spreading the conditioner onto the soil and then tilling it with a rotary tiller. This method is inefficient and results in uneven application of the conditioner. Therefore, it is necessary to design a soil conditioner application machine. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the prior art by providing a soil conditioner applicator. This soil conditioner applicator has a cleverly designed structure, high applicability, and uniform applicability.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A soil conditioner applicator includes a rotary tiller. A hopper is symmetrically mounted on the top of the rotary tiller. A screw conveyor housing is horizontally connected to the bottom of the hopper. Two open-bottomed material troughs, designated as hopper 1 and hopper 2, are fixedly connected to both ends of the screw conveyor housing. The lower ends of both hoppers pass through the top cover of the rotary tiller. A conveying shaft is rotatably mounted inside the screw conveyor housing. One end of the conveying shaft is rotatably connected to hopper 1, and the other end is connected to a hydraulic motor mounted on the outside of hopper 2. A positive spiral blade is mounted on one half of the conveying shaft, and a negative spiral blade is mounted on the other half. The positive and negative spiral blades convey the solid soil conditioner into hoppers 1 and hopper 2. The hopper is supported on the rotary tiller by the screw conveyor housing, hoppers 1 and hopper 2. Alternatively, an additional support frame can be installed on the rotary tiller to support the hopper. The material feeding troughs 1 and 2 are hollow, open-bottomed cuboids, and the tops can also be opened for easy observation of the material feeding process.

[0008] A further preferred embodiment: the lower ends of both the first and second material drop troughs extend directly above the rotary tiller's rotary shaft. Solid soil conditioner falls directly above the rotary shaft, and the rotary blades shred, crush, and disperse the conditioner, mixing it with the soil turned up during rotary tillage. This achieves more uniform application of the solid soil conditioner than methods that involve dropping it from the front or rear of the rotary shaft.

[0009] A further preferred embodiment: To avoid obstructing the installation of the screw conveyor housing, the first material trough seat, and the second material trough seat, a rotary tiller with a centrally located rotary tiller gearbox is suspended. The rotary tiller includes a rotary tiller frame, with a side cantilever seat at the front end for connection to the side cantilever of a tractor, and a middle cantilever seat above the front end for connection to the middle cantilever of the tractor. A rotary tiller gearbox is installed in the middle of the rotary tiller frame, and a rotary tiller shaft is symmetrically installed on both sides of the lower end of the gearbox. One end of the rotary tiller shaft is connected to the gearbox, and the other end is rotatably connected to the rotary tiller frame. Rotary tiller blades are installed on the rotary tiller shafts. The gearbox is connected to a power input shaft for connection to the tractor for power take-off. A top cover plate seals the top surface of the rotary tiller frame. The tractor's side cantilever is connected to the side cantilever seat, and the tractor's middle cantilever is connected to the middle cantilever seat. The raising and lowering of the spreader is controlled by the tractor's side and middle cantilever arms. The tractor pulls and drives the spreader. The power output from the tractor is transmitted through the power input shaft to the rotary tiller gearbox. After gear transmission, the rotary tiller shaft rotates, which in turn drives the rotary tiller blades to rotate and till the soil. During the spreading operation, solid soil conditioner is put into the hopper. The hydraulic motor drives the conveying shaft to rotate, which in turn drives the positive and negative spiral blades to convey the solid soil conditioner from the hopper to both ends of the screw conveyor housing. The positive spiral blades convey the solid soil conditioner to the first discharge trough, and the negative spiral blades convey the solid soil conditioner to the second discharge trough. The solid soil conditioner falls downward from the bottom of the first and second discharge troughs, which are located directly above the rotary tiller shaft. The rotary tiller blades cut, crush, and disperse the solid soil conditioner, mixing it with the soil turned up during the rotary tillage operation, achieving uniform spreading of the solid soil conditioner. Spreading can be completed in one tillage operation, resulting in high spreading efficiency.

[0010] A further preferred embodiment: a mudguard is hinged to the rear end of the rotary tiller frame. The lower end of the mudguard has a lower hinge lug, which is hinged to a limit adjustment shaft. Correspondingly, an upper hinge lug is provided on the rotary tiller frame, and a sliding sleeve is hinged to the upper hinge lug. An upper limit spring is installed at the upper end of the limit adjustment shaft passing through the sliding sleeve, and a lower limit spring is installed on the limit adjustment shaft at the lower end of the sliding sleeve. The limit adjustment shaft between the upper and lower limit springs can slide up and down within the sliding sleeve, allowing the mudguard to swing vertically and adaptively according to soil level. The mudguard prevents solid soil conditioner and soil turned up during rotary tillage from splashing backward, and also prevents solid soil conditioner and soil from falling into layers.

[0011] A further preferred embodiment: The rotary tiller has a rearwardly extending lifting rod hinged to a lifting rod. The front end of the lifting rod is hinged to another lifting rod, and the rear end of the lifting rod is fixedly connected to a laterally arranged spreading pole. The rear end of the lifting rod is fixedly connected to the middle of the spreading pole. A hydraulic cylinder for controlling the up-and-down swing of the lifting rod is mounted on the rotary tiller via a hydraulic cylinder mounting seat. The cylinder seat of the hydraulic cylinder is hinged to the hydraulic cylinder mounting seat via a hydraulic cylinder hinge lug, and the piston rod of the hydraulic cylinder is hinged to the lifting rod via a piston rod hinge lug. When solid soil conditioner needs to be added to the hopper, it is placed in a container. Then, the lifting rod is controlled by the hydraulic cylinder to swing downward, lowering the spreading pole and suspending the container containing the solid soil conditioner on the spreading pole. Finally, the lifting rod is controlled to swing upward, raising the spreading pole and thus lifting the container containing the solid soil conditioner above the hopper. The solid soil conditioner in the container is then poured into the hopper. This reduces manual handling and lifting operations, lowering labor intensity.

[0012] This soil conditioner spreader consists of a hopper containing solid soil conditioner mounted on a rotary tiller. A forward and reverse screw conveyor at the bottom of the hopper drops the solid soil conditioner to both ends. The rotary tiller blades then shred and disperse the falling solid soil conditioner, mixing it with the soil turned up during the rotary tillage process. This achieves uniform application of the solid soil conditioner. Its ingenious design results in high application efficiency. Attached Figure Description

Detailed Implementation

[0019] To provide a more detailed description of this utility model, the following description, in conjunction with the embodiments and accompanying drawings, will further illustrate this utility model. Example 1

[0020] A soil conditioner applicator includes a rotary tiller. A hopper 7 is symmetrically mounted on the top of the rotary tiller. A screw conveyor housing 6 is horizontally connected to the bottom of the hopper 7. Two open-bottomed material trough seats, one 3 and the other 10, are fixedly connected to both ends of the screw conveyor housing 6. The lower ends of both material trough seats 13 and 10 pass through the top cover plate 13 of the rotary tiller. A conveying shaft 4 is rotatably mounted inside the screw conveyor housing 6. One end of the conveying shaft 4 is rotatably connected to the material trough seat 13, and the other end is connected to a hydraulic motor 11 mounted on the outside of the material trough seat 10. A positive spiral blade 5 is mounted on one half of the conveying shaft 4, and a negative spiral blade 8 is mounted on the other half. The hopper 7 is supported on the rotary tiller by the screw conveyor housing 6, the material trough seat 13, and the material trough seat 20. Alternatively, an additional support frame can be installed on the rotary tiller to support the hopper 7. The material feeding trough seat 1 (3) and the material feeding trough seat 2 (10) are hollow, open-bottomed cuboids, and the top can also be opened to facilitate observation of the material feeding situation.

[0021] The lower ends of the material trough seat 1-3 and the material trough seat 2-10 extend directly above the rotary tiller shaft 1.

[0022] To avoid hindering the installation of the screw conveyor housing 6, the first material trough seat 3, and the second material trough seat 10, a rotary tiller with a centrally located rotary tiller gearbox 13 is suspended. The rotary tiller includes a rotary tiller frame 17. The front end of the rotary tiller frame 17 is provided with a side cantilever seat 9 for mounting and connecting with the side cantilever of a tractor. Above the front end of the rotary tiller frame 17 is a middle cantilever seat 14 for mounting and connecting with the middle cantilever of a tractor.

The tractor's side boom and intermediate boom control the raising and lowering of the spreader. The tractor pulls and drives the spreader. The power output from the tractor is transmitted through the power input shaft 12 into the rotary tiller gearbox 13. After gear transmission, it drives the rotary tiller shaft 1 to rotate, thereby driving the rotary tiller blades 2 to rotate and till. During the application process, solid soil conditioner is fed into hopper 7. The hydraulic motor 11 drives the conveying shaft 4 to rotate, thereby causing the positive spiral blade 5 and the negative spiral blade 8 to convey the solid soil conditioner from hopper 7 to both ends of the screw conveyor housing 6. The positive spiral blade 5 conveys the solid soil conditioner to the first material drop trough 3, and the negative spiral blade 8 conveys the solid soil conditioner to the second material drop trough 10. The solid soil conditioner falls downward from the bottom of the first material drop trough 3 and the second material drop trough 10, which are located directly above the rotary tillage shaft 1. The rotary tillage blade 2 cuts, crushes, and disperses the solid soil conditioner, and mixes it with the soil turned up during the rotary tillage operation, achieving uniform application of the solid soil conditioner. Application can be completed in one tillage operation, resulting in high application efficiency.
