[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes in which A and B are satisfied at the same time. In addition, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist.

[0028] See also Figures 1 to 4 As shown, the utility model is a cooling device suitable for granular fertilizer, comprising a bracket 1, characterized in that an oblique hopper 2 is provided on the bracket 1, a conveyor belt 4 is provided below the hopper 2, a suction device 14 and a negative pressure fan 15 are provided inside the conveyor belt 4, and the suction device 14 is provided between the hopper 2 and the negative pressure fan 15;

[0029] The conveyor belt 4 is provided with large holes 4a and small holes 4b in an alternating manner, and the aperture of the large holes is smaller than the diameter of the granular fertilizer.

[0030] How it works

[0031] The granular fertilizer produced is usually mixed with some powdered raw materials. The granular fertilizer mixed with powdered raw materials falls from the hopper to the conveyor belt. The discharge speed is adjusted by adjusting the screw according to the conveying speed.

[0032] The suction device can suck the powdered raw materials on the conveyor belt. On the one hand, it can recycle the powdered raw materials, and on the other hand, it can remove the powdered raw materials mixed in the granular fertilizer. At the same time, it can also avoid the negative pressure port from being blocked when the subsequent negative pressure distributor is cooled.

[0033] The suction device and negative pressure extension unit can be purchased from the market, and there is no restriction on the specific model.

[0034] In some embodiments, see Figure 2 and 3 As shown, a height-adjustable material control plate 8 having the same cross-section as the material outlet is provided at the material outlet of the hopper 2;

[0035] The material outlet is provided with a plate groove adapted to the material control plate 8, and the material control plate 8 is movably installed in the plate groove;

[0036] The material control plate 8 is mounted on a nut seat 10 with adjustable height via an adjusting screw 9. The nut seat 10 is fixed to a support plate 7, which is fixed to the hopper 2. It should be noted that this arrangement allows the material discharge amount to be adaptively adjusted according to the speed of the conveyor belt. That is, the material control plate can be raised or lowered by turning the adjusting screw to achieve material control.

[0037] In some embodiments, see Figure 1 and 4 As shown, the conveyor belt 4 is provided with protection strips 6 on both sides, and the protection strips 6 are bonded to the outside of the large hole 4a and the small hole 4b. The protection strips are used to prevent the granular fertilizer on the conveyor belt from falling from both sides.

[0038] In some embodiments, see Figure 1 As shown, the conveyor belt 4 is mounted on the pulley 3, and both sides of the pulley 3 are mounted on the bracket 1 through the bearing seat 5. A motor is installed on any pulley through a coupling to drive the pulley and then drive the conveyor belt to move. The motor is a speed-regulating motor.

[0039] In some embodiments, see Figure 1 As shown, the material control plate 8 is provided with an annular groove 8a;

[0040] One end of the adjusting screw 9 is rotatably mounted in the annular groove 8a, and the other end is provided with an adjusting handle.

[0041] In some embodiments, see Figure 1 As shown, polished rods 11 are provided on both sides of the adjusting screw 9, and the bottoms of the polished rods 11 are fixed on the material control plate 8;

[0042] The shaft of the polished rod 11 can also be movably installed in a slip ring 12 , and the slip ring 12 is fixed on the support plate 7 .

[0043] In some embodiments, see Figure 1 As shown, the spacing L between the two relative large holes 4a is less than 2 times the diameter of the granular fertilizer. In this way, the granular fertilizer can be prevented from blocking all the holes on the conveyor belt, resulting in weakened suction and cooling effects.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
