Description

Technical Field

[0001] The utility model relates to the technical field of batching devices, in particular to a soil conditioner batching and mixing device. Background Art

[0002] Using soil conditioners to improve the physical, chemical, and biological properties of soil, making it more suitable for plant growth, has become an important method for improving agricultural soil. Preparation of soil conditioners requires mixing organic materials such as livestock and poultry manure, industrial waste such as phosphogypsum, and microbial agents, with the proportions of these materials varying significantly. Existing soil conditioner batching devices typically add the different materials directly to a mixing tank for mixing, making it difficult to evenly mix smaller amounts of material.

[0003] For example, the utility model patent with publication number CN218307289U discloses a mixing device for producing soil conditioner, comprising: a screening box with a feed hole at the bottom of the screening box; a mixing assembly, the mixing assembly being arranged on the bottom surface of the screening box and connected to the screening box through the feed hole; a screening assembly, the screening assembly being arranged in the screening box, the screening assembly comprising: two mounting plates, multiple springs, a vibration motor, a frame, two limit chutes, a screening bin, two limit sliders, a lock body and a lock tongue slot, the two mounting plates being respectively arranged on the inner walls of both sides of the screening box, the multiple springs being respectively arranged on the two mounting plates, the vibration motor being arranged on the mounting plates, the frame being arranged on the springs, the upper part of the frame being provided with two limit chutes, the screening bin being provided with two limit sliders, the limit sliders being arranged in the limit chutes, and the lock body being arranged on the frame. Thus, powders of various components can be effectively screened and efficiently mixed to obtain high-quality soil conditioner.

[0004] Although this technical solution can screen powder materials and mix them efficiently, it is still not suitable for evenly dispersing and mixing small amounts of materials into a large amount of materials. In view of this, we propose a soil conditioner batching and mixing device. Utility Model Content

[0026] The following is a clear and complete description of the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1-4 As shown, the utility model provides a technical solution:

[0028] A soil conditioner batching and mixing device includes a mixing box 1, with a plurality of feed hoppers 2 regularly distributed on the top of the mixing box 1. A plurality of crushing rollers 8 arranged side by side are rotatably mounted in the feed hoppers 2. A plurality of support frames 3 for mounting the feed hoppers 2 are fixedly mounted on the top surface of the mixing box 1. A horizontally arranged support plate 4 is fixedly connected to the top of the support frame 3. A plurality of weight sensors 5 are mounted on the top surface of the support plate 4. A plurality of pressing plates 6 are mounted on the outer wall of the feed hopper 2, the number of which is equal to that of the weight sensors 5 and the positions of which correspond one to one. The pressing plates 6 are mounted on the weight sensors 5 at corresponding positions.

[0029] Two first inclined plates 14 and second inclined plates 16 with opposite inclination directions are provided near the top of the mixing box 1. A stirring shaft 20 extending to the bottom of the mixing box 1 is also rotatably installed inside the mixing box 1, and a number of regularly distributed stirring blades 21 are fixedly installed on the outer wall of the stirring shaft 20.

[0030] In this embodiment, an avoidance hole 7 is provided on the support plate 4 for the feeding funnel 2 to pass through. The aperture of the avoidance hole 7 is larger than the outer diameter of the corresponding feeding funnel 2 and the outer wall of the feeding funnel 2 does not contact the support plate 4, thereby reducing friction and damage caused by contact between the two; a number of weight sensors 5 are regularly distributed along the avoidance hole 7, and the pressure plate 6 is arranged horizontally, so that the weight sensor 5 and the pressure plate 6 form a scale structure, which is convenient for sampling and weighing at any time. When the weight of the material in the feeding funnel 2 reaches the preset weight, it is discharged into the mixing box 1 to realize quantitative feeding.

[0031] Furthermore, the bottom discharge pipe of the feed hopper 2 passes through the top sidewall of the mixing box 1 and extends into the mixing box 1. A discharge valve 11 is installed on the discharge pipe of the feed hopper 2 to facilitate discharge of the material after reaching a preset weight condition. When the material is added to the feed hopper 2, the weight is sampled at any time and monitored by the weight sensor 5. When the set value is reached, the discharge valve 11 is opened and the discharge valve 11 is activated to start discharging.

[0032] In this embodiment, a gear set 9 for synchronous rotation of several crushing rollers 8 is also provided in the feed funnel 2. The gear set 9 includes several gears fixedly connected to the same end of the several crushing rollers 8. The number of gears is equal to the number of crushing rollers 8 and corresponds one to one. The several gears are meshed with each other in sequence. A motor 10 is also installed on the feed funnel 2 by bolts. The output shaft of the motor 10 is coaxially keyed with the rotating shaft of one of the crushing rollers 8. The motor 10 can drive the several crushing rollers 8 to break up the lumps in the material.

[0033] Among them, the distribution of the gear set 9 includes two structures. First, the gear set 9 includes a plurality of gears fixedly connected at the same end of the plurality of crushing rollers 8. The number of gears is equal to and corresponds to the number of crushing rollers 8. At the same time, the plurality of gears are meshed one by one in sequence. At this time, the motor 10 rotates, which can make every two adjacent crushing rollers 8 rotate in opposite directions; second, the gear set 9 includes a plurality of gears fixedly connected at the same end of the plurality of crushing rollers 8. The number of gears is equal to and corresponds to the number of crushing rollers 8. At the same time, there is an intermediate transmission gear meshed between every two adjacent gears. At this time, the motor 10 rotates, which can make the plurality of crushing rollers 8 rotate in the same direction at the same time.

[0034] In this embodiment, the higher ends of the first inclined plate 14 and the second inclined plate 16 are fixedly connected to the inner wall of the mixing box 1 on the corresponding side, and a gap is left between the lower ends of the first inclined plate 14 and the second inclined plate 16 and the inner wall of the mixing box 1 on the other side; a plurality of first through holes 15 and second through holes 17 are respectively opened on the first inclined plate 14 and the second inclined plate 16; the aperture of the first through hole 15 is larger than the aperture of the second through hole 17, so that the unloading speed of the first inclined plate 14 is greater than the unloading speed of the second inclined plate 16, that is, the first inclined plate 14 is more suitable for the diversion and unloading operation of materials with larger consumption.

[0035] In this embodiment, several feeding funnels 2 are divided into different sizes, among which several relatively large feeding funnels 2 and several relatively small feeding funnels 2 are respectively located on both sides of the top surface of the mixing box 1; several relatively large feeding funnels 2 are located above the higher end of the first inclined plate 14, and several relatively small feeding funnels 2 are located above the higher end of the second inclined plate 16; this structural design can pre-crush the material with a larger amount through the larger feeding funnel 2, and then screen it through the first inclined plate 14 with a larger through hole; similarly, the material with a smaller amount is pre-crushed through the smaller feeding funnel 2, and then screened through the second inclined plate 16 with a smaller through hole.

[0036] In this embodiment, the second inclined plate 16 is located above the first inclined plate 14, and a gap is left between the bottom end of the second inclined plate 16 and the first inclined plate 14 to prevent the second inclined plate 16 from affecting the normal material discharge of the first inclined plate 14; vibrators 18 are fixedly installed on the bottom surfaces of the first inclined plate 14 and the second inclined plate 16. The vibrator 18 can drive the first inclined plate 14 and the second inclined plate 16 to vibrate, thereby causing the material on the first inclined plate 14 and the second inclined plate 16 to slide, and causing the material to pass through the first through hole 15 and the second through hole 17, thereby preventing the first through hole 15 and the second through hole 17 from being blocked.

[0037] In this embodiment, the first inclined plate 14 and the second inclined plate 16 are both provided with through holes at the central axis of the mixing box 1 for accommodating the passage of the stirring shaft 20, and several stirring blades 21 are all located below the first inclined plate 14, so that the stirring operation is carried out below the two inclined plates, and the stirring blades 21 will not collide with the inclined plates; the length of the stirring blades 21 is less than the radius of the inscribed circle of the cross section of the mixing box 1, ensuring that the stirring blades 21 can operate normally and will not collide with the side wall of the mixing box 1.

[0038] The mixing box 1 can also be configured to be cylindrical, so as to avoid the existence of internal mixing dead corners or accumulation of residual materials at the corners of the box.

[0039] In this embodiment, a stirring motor 19 is fixedly installed at the center of the top surface of the mixing box 1 by bolts. The output shaft of the stirring motor 19 is coaxially keyed to the top of the stirring shaft 20, and the stirring shaft 20 is driven to rotate by the stirring motor 19.

[0040] In this embodiment, a bracket 12 is fixedly installed on the top surface of the mixing box 1, and a pressure roller 13 is rotatably connected to the bottom end of the bracket 12. The pressure roller 13 is located above the first inclined plate 14 with a gap between the two. A number of spikes are evenly fixedly installed on the circumferential outer wall of the pressure roller 13, which are used to crush and crush large amounts of materials falling on the first inclined plate 14, further crush the materials and avoid agglomeration.

[0041] At the same time, a driving motor is also installed on the mixing box 1 , and the output shaft of the driving motor is coaxially keyed to the rotating shaft of the pressing roller 13 to provide power for the operation of the pressing roller 13 .

[0042] When the soil conditioner batching and mixing device of the present invention is used, firstly, a larger amount of material is put into the feed funnel 2 above the first inclined plate 14, and a smaller amount of material is put into the feed funnel 2 above the second inclined plate 16; the weight sensor 5 detects the weight of the feed funnel 2, and when the material in the feed funnel 2 is fermented or naturally dried until the moisture reaches the set value, the discharge valve 11 is opened, and the discharge valve 11 starts to discharge; the larger amount of material falls on the first inclined plate 14 and slides along it, and part of the material falls through the first through hole 15; the smaller amount of material falls on the second inclined plate 16 and slides along it, And part of the material falls onto the material on the first inclined plate 14 below through the second through hole 17, so that the material with a smaller amount can be pre-mixed with the material with a larger amount before stirring; controlling the operation of the vibrator 18 can drive the first inclined plate 14 and the second inclined plate 16 to vibrate, causing the material on the first inclined plate 14 and the second inclined plate 16 to slide, and causing the material to pass through the first through hole 15 and the second through hole 17, thereby preventing the first through hole 15 and the second through hole 17 from being blocked; turning on the stirring motor 19, the stirring motor 19 drives the stirring shaft 20 and the stirring blade 21 to rotate, stirring the material in the mixing box 1 to make it fully and evenly mixed.
