[0013] A method for producing a mineral soil conditioner comprises the following steps:

[0014] Step 1, raw material screening: After pouring the raw materials into the fixed outer shell, the raw materials reach the screening part. When the screening part rotates, it screens the raw materials.

[0015] Step 2, raw material gathering: After the raw materials are screened, the screening plate is of an inclined structure, and the agglomerated raw materials gather at the connection between the screening plate and the fixed ball due to gravity.

[0016] Step 3, grinding particle control: The grinding head moves downward to grind the gathered raw materials. By measuring the height of the grinding head's descent through the scale, the diameter of the ground particles is controlled.

[0017] Step 4, variable speed control: For grinding raw materials with different particle diameters in Step 3, the rotation speed of the screening part is controlled. After grinding, the operation of Step 1 is repeated again.

[0018] Step 5, chemical agent spraying: The raw materials screened in Step 1 fall to the bottom of the fixed outer shell. The chemical agent is sprayed out from the spraying block, and the chemical agent is stirred and mixed with the raw materials to neutralize the soil pH value.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] First, through the variable frequency motor, the reciprocating motion of the screening part is controlled. The raw materials move together with the screening part. Due to the structure of the screening plate, the raw materials move outward due to centrifugal force. During this process, the raw materials shift relative to each other, avoiding the mutual accumulation of raw materials and also reducing the probability of raw material clogging of the screening holes, greatly increasing the screening speed of the raw materials.

[0021] Second, after screening, the grinding head grinds the non-conforming raw materials. The grinding head moves to different heights, changing the distance between the grinding head and the screening plate, grinding the raw materials into different particle diameters. During the downward movement of the grinding head, the speed of the screening part will change accordingly, controlling the rotation speed of the screening part to prevent the raw materials from leaving the range of the grinding head due to centrifugal force.

[0022] Third, a chemical agent is added to the screened raw materials to neutralize the soil pH value, making the soil more conducive to the growth of crops. Description of the Drawings

Specific embodiments

[0029] In order to deepen the understanding and recognition of the present invention below, the technical solutions in the embodiments of the present invention will be clearly and completely described and introduced with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments, and no formal restrictions are imposed on this embodiment. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0030] Please refer to Figures 1-5, the present invention provides a technical solution: a production device for a mineral soil conditioner, including a fixed outer shell 1. At the bottom of the inner shell of the fixed outer shell 1, there is a connecting column 7. The upper end of the connecting column 7 is fixedly connected with a screening member 6 for screening the soil particle size. On the inner shell wall of the fixed outer shell 1, there is a support ring 2 fixedly connected for supporting and restricting the screening member 6. The lower end of the connecting column 7 is fixedly connected with a connecting shaft 10. Both ends of the connecting shaft 10 penetrate through the fixed outer shell 1. At the lower end of the fixed outer shell 1, there is a variable-frequency motor. At least two F-shaped stirring rods 12 are fixedly connected to the side end of the connecting column 7. Above the screening member 6, there is a grinding head 3 for grinding the compacted soil. The upper end of the grinding head 3 is fixedly connected to the inner shell of the fixed outer shell 1. The upper end of the grinding head 3 is fixedly connected with a scale 4 for positioning its height. Inside the connecting column 7, there is a connecting hole 8. Inside the connecting hole 8, there is a regulating plate 15. On the inner wall of the connecting hole 8, there is a speed regulating plate 9 for controlling the rotation speed of the screening member 6 and the grinding efficiency of the grinding head 3. On the side end of the speed regulating plate 9, there is an extrusion plate 17. On the side end of the connecting column 7, there is a spraying block 11. Inside the spraying block 11, there is a placement cavity 20. Inside the placement cavity 20, there is a dosage control mechanism 21 for regulating the dosage of the medicament spraying. The dosage control mechanism 21 is slidably connected with the speed regulating plate 9. The speed regulating plate 9 is used to control the rotation speed of the screening member 6. The screening member 6 is composed of a fixed ball 61, a screening plate 62, screening holes 63 and a support portion 64. The speed regulating plate 9 is composed of a fixed portion 91, a deformable portion 92 and a positioning portion 93. The speed regulating plate 9 and the dosage control mechanism 21 cooperate with each other to control the medicament spraying speed. The dosage control mechanism 21 is composed of a telescopic rod 211, a telescopic head 212, an elastic plate 213 and a sealing plug 214.

[0031] The screening plate 62 is of a fan-shaped structure. The screening holes 63 are located in the middle of the screening plate 62. There are at least two screening plates 62. The screening plates 62 form a funnel structure. The lower end of the screening plate 62 is connected to the fixed ball 61 by a buckle or a bolt. By combining different numbers of screening plates 62 into a funnel-shaped structure, when the raw material falls on the screening plate 62, due to gravity, it all concentrates on the lower side part. After the screening plate 62 is driven to rotate reciprocally, the raw material will move due to centrifugal force, causing the raw material to move out of position. This method can effectively avoid the blockage problem caused by the accumulation and extrusion of the raw material compared with the traditional vibration screening method. At the same time, it can also throw out the raw material blocking the screening holes 63, avoiding the occurrence of blockage and making the raw material screening faster.

[0032] The supporting part 64 is in a hook-like structure. The supporting part 64 is fixedly connected to the upper end of the screening plate 62. There is a supporting groove on the outer side wall of the supporting ring 2. The supporting groove is in an L-shaped structure. There are supporting balls 13 on the inner wall of the supporting groove. The supporting part 64 is clamped with the supporting balls 13. The supporting ring 2 and the supporting balls 13 cooperate with each other to limit and support the screening plate 62, and at the same time can reduce the frictional resistance when the screening plate 62 rotates.

[0033] There is a grinding cavity 14 in the middle of the lower end of the grinding head 3. The lower end of the grinding cavity 14 matches the grinding head 3. The upper end surface of the grinding head 3 is an inclined surface. There is an electric push rod 5 fixedly connected between the middle of the upper end of the grinding head 3 and the inner wall of the fixed housing 1. The side end surface of the grinding head 3 faces the screening plate 62. There are at least four grinding balls 16 embedded in the side end surface of the grinding head 3. After the raw materials are screened, the grinding head 3 moves downward, and the distance that the grinding head 3 moves downward is penetrated by the scale 4. At this time, the screening part 6 continues to rotate. The two cooperate with each other to grind the raw materials that do not meet the requirements, thus avoiding the repeated operation process and making the screening work faster and more convenient.

[0034] Both the deformation part 92 and the positioning part 93 are formed by stamping the fixed part 91. The front end of the deformation part 92 is in an arc structure. An L-shaped structure is formed between the tail end of the deformation part 92 and the fixed part 91. The left side of the positioning part 93 is an inclined structure, and the right side of the positioning part 93 is a vertical structure. The upper end of the regulation plate 15 penetrates the screening part 6. There are balls embedded in the upper end of the regulation plate 15. There is a spring at the lower end of the regulation plate 15. The upper end of the regulation plate 15 is located at the grinding head 3. The extrusion plate 17 is fixedly connected to the side end of the regulation plate 15. The upper half part of the left side surface of the extrusion plate 17 is an inclined surface. A conductive head 19 is fixedly connected to the lower half part of the left side surface of the extrusion plate 17. A conductive contact 18 is fixedly connected to the side end of the positioning part 93. When the grinding head 3 moves downward, the grinding head 3 squeezes the regulation plate 15, pushing the regulation plate 15 downward to make the conductive head 19 contact the conductive contacts 18 at different positions, thereby controlling the torque output of the frequency conversion motor and reducing the rotation speed of the screening part 6 to prevent the raw materials from being thrown out of the range of the grinding head 3 due to large centrifugal force during the grinding process.

[0035] Both ends of the telescopic rod 211 penetrate through the spraying block 11 and the fixing part 91. The telescopic head 212 and the sealing plug 214 are respectively fixedly connected to both ends of the telescopic rod 211. The opening of the placement cavity 20 is a circular hole structure. The sealing plug 214 is located at the opening of the placement cavity 20. The sealing plug 214 is a frustum structure. The telescopic head 212 abuts against the arc part of the deformation part 92. The elastic plate 213 is fixedly connected to the lower end of the telescopic rod 211. The elastic plate 213 is an arc structure. The top end of the elastic plate 213 abuts against the side end face of the fixing part 91. When the control plate 15 moves downward by different distances, the deformation degree of the deformation part 92 squeezed by the pressing plate 17 is different. The deformation part 92 can push the telescopic rod 211 to move, thereby changing the plugging relationship between the sealing plug 214 and the opening of the placement cavity 20, so as to spray different doses of medicament.

[0036] A production and preparation method of a mineral soil conditioner includes the following steps:

[0037] Step 1, raw material screening: After pouring the raw materials into the fixed outer shell 1, the raw materials reach the screening part 6. When the screening part 6 rotates, it screens the raw materials;

[0038] Step 2, raw material gathering: After the raw material screening is completed, the screening plate 62 is an inclined structure, and the agglomerated raw materials gather at the connection between the screening plate 62 and the fixed ball 61 due to gravity;

[0039] Step 3, grinding particle control: The grinding head 3 moves downward to grind the gathered raw materials. By means of the scale 4 passing through the descending height of the grinding head 3, the diameter of the grinding particles is controlled;

[0040] Step 4, speed change control: For grinding different particle diameters in Step 3, the rotation speed of the screening part 6 is controlled. After grinding is completed, the operation of Step 1 is repeated again;

[0041] Step 5, medicament spraying: The raw materials screened in Step 1 fall to the bottom of the fixed outer shell 1. The medicament is sprayed out from the spraying block 11, and the medicament is stirred and mixed with the raw materials to neutralize the soil pH.
