Description

Technical Field

[0001] The utility model relates to the technical field of water-soluble fertilizer production devices, in particular to a water-soluble fertilizer raw material clot crushing device. Background Art

[0002] Water Soluble Fertilizer (WSF) is a multi-component compound fertilizer that can be completely soluble in water. It can dissolve quickly in water and is more easily absorbed by crops. Its absorption and utilization rate is relatively high. More importantly, it can be used in facility agriculture such as sprinkler and drip irrigation to achieve water-fertilizer integration and save water, fertilizer and labor. Generally speaking, water-soluble fertilizers can contain all the nutrients needed for crop growth, such as N, P, K, Ca, Mg, S and trace elements, etc. Therefore, people can design formulas according to the nutritional requirements of crop growth. Scientific formulas will not cause waste of fertilizers, making their fertilizer utilization rate about 2-3 times that of conventional compound chemical fertilizers. Secondly, water-soluble fertilizers are fast-acting fertilizers, which allow growers to see the effects and performance of fertilizers more quickly, and can adjust the fertilizer formula at any time according to the different growth of crops. At the same time, it can be fertilized during irrigation with irrigation water, including sprinkler irrigation, drip irrigation, etc., which not only saves water, fertilizers, but also labor. It is more and more widely used in the agricultural field and the demand is also increasing.

[0003] In the production process of water-soluble fertilizers, raw materials are mainly divided into two categories: liquid raw materials and powdered raw materials. Since liquid raw materials are not as convenient to transport as powdered raw materials, companies use more powdered raw materials in the production process of water-soluble fertilizers. In order to ensure the supply of production, a large amount of powdered raw materials are often stored in the factory. Some powdered raw materials have certain hygroscopicity and are prone to agglomeration and compaction during storage, which is particularly serious in summer. Therefore, before the raw materials are put into use, the agglomerated and compacted raw materials need to be crushed to ensure the processing efficiency and quality of the water-soluble fertilizers.

[0004] At present, the crushing of agglomerated and compacted raw materials mainly relies on manual crushing with the help of auxiliary tools, which is inefficient and inconvenient. There are also some agglomerate crushing devices on the market, such as patent number CN215087536U, and the patent name is a highly efficient and safe pesticide powder agglomerate crushing device. The device has a relatively complex structure and can process agglomerated pesticides through graded crushing. It is suitable for small-batch products such as pesticides. However, it is difficult to meet the processing needs for large-scale products such as water-soluble fertilizer powder raw materials. Utility Model Content

At the same time, the clotted raw material can be preliminarily crushed by the conveying roller group 3, and the bottom of the conveying roller group 3 is inclinedly provided with a first sieve plate 4. Since the bagged water-soluble fertilizer powder raw material is not all clotted, the water-soluble fertilizer powder raw material that is not clotted and meets the aperture size can be screened by the first sieve plate 4 and directly passes through the second collecting plate 14 The first sieve plate 4 is tilted at the bottom end thereof and connected to a guide plate 5. A conveying channel 6 is formed between the guide plate 5 and the inner wall of the box body 1. A support plate 7 is tilted at the bottom of the conveying channel 6. The support plate 7 is densely covered with sieve holes. At the same time, sieve holes are also provided on the first sieve plate 4 and the second sieve plate 10.

The bottom end of the second sieve plate 10 extends to the outside of the box body 1 and is connected to the first discharge chute 11.

[0040] A first collecting plate 12 is provided below the second sieve plate 10. The bottom end of the first collecting plate 12 extends to the outside of the box body 1 and is connected to a second discharge chute 13.

The agglomerated raw materials are crushed through the crushing plate 9 and the supporting plate 7. The crushed raw materials fall onto the second sieve plate 10 through the sieve holes on the supporting plate 7. The crushed raw materials are then sieved by the second sieve plate 10. After screening, the water-soluble fertilizer powder raw materials that meet the aperture size fall through the sieve holes on the second sieve plate 10 to the first collecting plate 12, and are transported to the second discharging trough 13 through the first collecting plate 12. A collecting box is usually arranged on the outside of the second discharging trough 13 or the second discharging trough 13 is directly connected to the water-soluble fertilizer mixing kettle.

In this way, the powder raw material clots are quickly crushed and screened, with a simple structure and high crushing efficiency.

[0042] like Figure 2-Figure 5 As shown, in the embodiment of the utility model, two connecting parts 901 are relatively fixedly installed on one side of the crushing plate 9 away from the support plate 7, and connecting plates 16 are respectively hingedly connected to the two connecting parts 901. A connecting shaft 17 movably penetrates between the two connecting plates 16, and one end of the connecting shaft 17 is eccentrically installed on the driving wheel 18, and the driving wheel 18 is connected to the output shaft of the motor 8. The motor 8 is installed on the box body 1, and the driving wheel 18 can be driven to rotate by the motor 8.

[0043] like Figure 2-Figure 5 As shown, in the present embodiment, limiting rods 19 are relatively provided on both sides of the connection part 901 along the movement direction of the crushing plate 9, and the two limiting rods 19 form a limiting space for the connection part 901. Both ends of the limiting rods 19 are installed on the box body 1, and a space for limiting the movement of the crushing plate 9 is formed between the limiting rods 19 and the support plate 7. By setting the limiting rods 19 and cooperating with the support plate 7, the movement direction of the crushing plate 9 can be limited, so that the crushing plate 9 can only move on the support plate 7 along the direction of the limiting rods 19, thereby realizing the extrusion and crushing of the coagulated raw materials.

[0044] like Figure 4 and Figure 5 As shown, in this embodiment, an inclined introduction portion 902 is provided at one end of the crushing plate 9 close to the feeding channel 6. The inclined introduction portion 902 facilitates the entry of the coagulated raw materials into the crushing space between the crushing plate 9 and the support plate 7, thereby facilitating the crushing of the coagulated raw materials.

[0045] A plurality of air-avoiding grooves 903 are arranged on one side of the crushing plate 9 close to the support plate 7. The setting direction of the air-avoiding grooves 903 is perpendicular to the movement direction of the crushing plate 9. By setting a plurality of air-avoiding grooves 903, the negative pressure adsorption effect generated by the crushing plate 9 and the support plate 7 when crushing the raw materials is eliminated, so that the crushed raw materials can smoothly pass through the sieve holes on the support plate 7 and fall to the second sieve plate 10.

[0046] like Figure 2-Figure 4 As shown, in the embodiment of the present utility model, the bottoms of the first sieve plate 4, the second sieve plate 10, the first collecting plate 12 and the second collecting plate 14 are all connected with springs 20, and the springs 20 are mounted on support blocks 21, and the support blocks 21 are all fixedly mounted on the inner wall of the box body 1;

[0047] At least one vibrator 22 is also installed at the bottom of the first sieve plate 4, the second sieve plate 10, the first collecting plate 12 and the second collecting plate 14 respectively. The vibrator 22 is common in daily life and belongs to the common knowledge of technicians in this technical field. It will not be repeated here. By arranging the spring 20 and the vibrator 22, the first sieve plate 4, the second sieve plate 10, the first collecting plate 12 and the second collecting plate 14 can vibrate during crushing, which is convenient for the movement and screening of powder raw materials.

[0051] like Figure 1-Figure 6 As shown, first, the bagged water-soluble fertilizer powder raw material of the clotted material is opened and poured into the hopper 2, and the raw material in the hopper 2 continuously falls onto the first sieve plate 4 through the conveying roller group 3. Since the bagged water-soluble fertilizer powder raw material is not all clotted, and after the initial crushing by the conveying roller group 3, the powder raw material that meets the size will pass through the sieve holes on the first sieve plate 4 and fall onto the second collecting plate 14. The powder raw material collected by the second collecting plate 14 falls to the second discharging trough 13 through the feeding pipe 15, and is directly output through the second discharging trough 13;

[0052] The remaining raw materials after being screened by the first sieve plate 4 enter through the feeding channel 6 and fall onto the support plate 7, and then enter the crushing space between the crushing plate 9 and the support plate 7. The motor 8 runs and drives the crushing plate 9 to reciprocate on the support plate 7 through the driving wheel 18 and the connecting plate 16, so as to realize the crushing of the raw materials in the crushing space. The crushed raw materials fall to the second sieve plate 10 through the sieve holes on the support plate 7, and the crushed raw materials are screened again by the second sieve plate 10. The powder raw materials that meet the size will fall onto the first collecting plate 12 through the sieve holes on the second sieve plate 10, and the powder raw materials collected by the first collecting plate 12 enter the second discharging trough 13 and are discharged through the second discharging trough 13.

[0053] The remaining raw materials after screening by the second sieve plate 10 are output through the first discharging chute 11. If the raw materials output by the first discharging chute 11 still do not meet the aperture size, they can be put back into the hopper 2 for re-crushing.
