DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

[0030] Therefore, the following detailed description of the embodiments of the present application is not intended to limit the scope of the claimed application, but only represents some embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0031] It should be noted that the embodiments and features and technical solutions in the embodiments in the present application can be combined with each other without conflict.

[0032] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0033] As Figures 1-5 shown, the present embodiment proposes a saline-alkali soil treatment improvement agent mixing device, which comprises a cylinder 1, and a grinding assembly 2 is arranged at the top of the cylinder 1, and an auxiliary assembly 3 is arranged below the grinding assembly 2.

[0034] As Figure 3 and Figure 5As shown, the grinding assembly 2 includes an entry hopper 201, a grinding pipe 202, a grinding motor 203, a grinding shaft 204, a grinding wheel 205, a feeding slot 206, a grinding part 207, and an auxiliary grinding block 208. The entry hopper 201 is arranged at the top of the barrel 1, the auxiliary grinding block 208 is arranged below the entry hopper 201, the grinding motor 203 is arranged at the inner bottom of the barrel 1, the grinding shaft 204 is bolted to the output shaft at the top of the grinding motor 203, the grinding wheel 205 is arranged at the top of the grinding shaft 204, a plurality of feeding slots 206 are arranged at the top of the grinding wheel 205, the grinding part 207 is arranged at the bottom of the grinding wheel 205, the auxiliary grinding block 208 is arranged on the inner side wall of the grinding pipe 202, the grinding part 207 and the auxiliary grinding block 208 are used in cooperation, the surfaces of the grinding wheel 205 and the auxiliary grinding block 208 are provided with irregular particles, and there is a gap of 3 mm between one end of the auxiliary grinding block 208 and the grinding shaft 204. After the material is poured into the entry hopper 201 at the top, it falls on the grinding block and is preliminarily crushed. After the grinding motor 203 is started, the grinding shaft 204 is driven to rotate, and the grinding wheel 205 at the top is driven to rotate at high speed; the feeding slot 206 at the top of the grinding wheel 205 pours the material into the grinding surface of the grinding wheel 205 at the bottom, and forms an extrusion and shearing action with the auxiliary grinding block 208 on the inner side wall of the barrel 1. The irregular particles on the surfaces of the two enhance the friction and crushing effect, and the auxiliary grinding block 208 and the grinding shaft 204 maintain a gap of 3 mm, which allows small particles to pass through secondary grinding and avoids direct contact to cause jamming, thereby achieving multi-stage particle size control.

[0035] As shown in Figure 3 and Figure 4 As shown, the auxiliary assembly 3 includes a shielding plate 301 and a storage basket 302. The shielding plate 301 is arranged at the bottom of the auxiliary grinding block 208, and the storage basket 302 is threadedly connected to the bottom of the barrel 1. The storage basket 302 is arranged below the auxiliary grinding block 208, and the shielding plate 301 is located at the bottom of the grinding block, which is used to adjust the falling speed of the material and prevent large particles that are not fully crushed from directly entering the storage basket 302. The storage basket 302 is connected to the bottom of the barrel 1 through threads, which is convenient for disassembly and cleaning. The position of the storage basket 302 is arranged below the auxiliary grinding block 208, which ensures that the fine particles processed by the grinding wheel 205 and the auxiliary grinding block 208 can accurately fall into the basket, realizes physical isolation of the grinding product and the processing area, and improves the operation safety.

[0036] As shown in Figure 4As shown, the inside of the storage basket 302 is provided with a filter screen 4, and the two sides of the filter screen 4 are provided with lifting rings 5 for lifting the filter screen 4. The aperture of the filter screen 4 is 1mm in diameter. The filter screen 4 in the storage basket 302 is designed with a 1mm aperture to intercept particles with excessive particle size and ensure that the discharged material meets the fineness standard required for treatment. The design of the lifting rings 5 on both sides allows the operator to manually lift the filter screen 4 for backwashing or replacement, solving the problem of easy clogging and difficult maintenance of traditional fixed filter screens 4. The filter screen 4 and the subsequent activated carbon layer 6 form a two-stage filtration system to improve the purity of the material.

[0037] As shown in Figure 4 , the inner bottom of the storage basket 302 is provided with an activated carbon layer 6, which is located at the bottom of the filter screen 4. The thickness of the activated carbon layer 6 is 3mm. The activated carbon layer 6 is located below the filter screen 4, and the 3mm thickness balances the adsorption efficiency and flow resistance. It adsorbs organic impurities, odors or trace chemical pollutants that may be mixed during the grinding process through the microporous structure, and is particularly suitable for the preparation of amendments that need to avoid secondary pollution during saline-alkali land treatment. The activated carbon and the filter screen 4 constitute a dual purification mechanism of physical interception and chemical adsorption to ensure the environmental friendliness of the improved material.

[0038] As shown in Figure 2 , the outer side of the cylinder 1 is provided with a temperature insulation layer 7 for protecting the cylinder 1. The thickness of the temperature insulation layer 7 is 10mm. The material of the temperature insulation layer 7 is aluminum silicate ceramic fiber felt. The 10mm temperature insulation layer 7 made of aluminum silicate ceramic fiber felt wraps the cylinder 1, effectively blocking the influence of external environmental temperature fluctuations on the grinding process. In high temperature seasons, it prevents the motor from overheating, causing the temperature in the cylinder to be too high and causing material to clump. In cold environments, it reduces heat loss to maintain grinding efficiency, ensuring that the device works stably in an environmental temperature range of -20℃ to 80℃.

[0039] As shown in Figure 2 , the outer side of the cylinder 1 is provided with a support ring 8, and the bottom of the support ring 8 is provided with a support leg 9. The bottom end of the support leg 9 is inclined downward. The support ring 8 is rigidly connected to the outer wall of the cylinder 1, evenly distributing the weight of the device to the four inclined support legs 9. The 15° to 30° outward inclination of the bottom end of the support leg 9 forms a trapezoidal stable structure, which can improve the lateral force resistance by 40% compared with vertical support, preventing the cylinder 1 from tilting during grinding vibration. The inclination angle also increases the projection area of the support surface, enhancing the adaptability to soft saline-alkali soil foundation.

[0040] As shown in Figure 2 , one side of the support leg 9 is provided with a fixed crossbar 10, which is horizontally arranged. The fixed crossbar 10 is connected to the two support legs 9 by arc welding, forming a closed force frame. It significantly improves the overall stiffness of the support structure through the principle of triangular stability, converting single-point bearing into distributed load. Avoiding structural loosening after long-term use.

[0041] Specifically, the saline soil treatment improver mixing device in use: the grinding device passes through the top access hopper 201 and guides the material into the grinding block for preliminary crushing, then the grinding motor 203 drives the grinding shaft 204 to drive the grinding wheel 205 to rotate at high speed, the material enters the grinding surface through the feed slot 206 on the top of the grinding wheel 205, and the auxiliary grinding block 208 (both surfaces are provided with irregular particles) on the inner wall of the cylinder 1 forms extrusion and shearing effect, 3mm dynamic gap realizes multi-stage particle size control, avoids jamming. The ground material falls into the bottom screw thread connected storage basket 302, first intercepts the oversized particles through the 1mm aperture filter screen 4, and then absorbs the organic pollutants by the 3mm activated carbon layer 6, forming a double mechanism of physical interception and chemical purification. The outer part of the cylinder 1 is wrapped with a 10mm aluminum silicate ceramic fiber felt temperature insulation layer 7, which ensures stable operation in an environment of-20℃ to 80℃; the supporting legs 9 are designed to be outwardly inclined at an angle of 15° to 30° and are welded to the horizontal rods 10, which improves the lateral force and adapts to the soft foundation of saline soil. The overall structure realizes efficient grinding and prevents secondary pollution through multi-stage crushing, gap regulation, double filtration and environmental adaptability design, and is optimized for saline soil improver preparation.

[0042] All the technical features in the embodiment can be freely combined according to actual needs.

[0043] The above embodiment is a preferred implementation scheme of the utility model, and the utility model can also be implemented in other ways, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the utility model.
