Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer processing, and particularly relates to a fertilizer crusher. Background Art

[0002] Fertilizer is an essential nutrient in the process of agricultural production. There are many production processes for fertilizers, including the pulverization of fertilizers.

[0003] The Chinese utility model patent with the authorization announcement number of "CN209333824U", specifically "a fertilizer crusher", through multiple pulverization operations, after the input fertilizer is preliminarily roll-pressed by a roll-pressing mechanism, the large-particle fertilizer is subjected to secondary hammering to improve the pulverization effect.

[0004] The above device inputs the large pieces of fertilizer to be pulverized from the feed inlet, and the input action is completely manually operated. Therefore, it is difficult to ensure uniform feeding, and then the amount of large pieces of fertilizer roll-pressed by the roll-pressing mechanism is not the same. There will be problems such as the initial pulverization load of the roll-pressing mechanism increasing or even the pulverization roller being blocked due to the instantaneous influx of large pieces of fertilizer into the roll-pressing mechanism, and there will also be a situation where the amount of large pieces of fertilizer flowing into the roll-pressing mechanism is less instantaneously, resulting in the roll-pressing mechanism idling. The amount of pulverized fertilizer obtained from the outlet end is uneven, which is not convenient for packaging, etc. All these are not conducive to the smooth pulverization operation of large pieces of fertilizer. Content of the Utility Model

[0005] In view of the above-mentioned drawbacks of the prior art, the utility model provides a fertilizer crusher, which can effectively solve the problems raised in the background art.

[0006] To achieve the above objectives, the utility model is realized through the following technical solutions:

[0007] The utility model provides a fertilizer crusher, which includes a machine base and two pulverization rollers that are reversely rotatably installed in the machine base and are distributed in a staggered manner. The feeding assembly includes two transmission rollers rotatably installed above the machine base. A metal mesh conveyor belt with a port opposite to the upper cavity opening of the machine base is jointly sleeved on the outer roller walls of the two transmission rollers. The buffer adjustment assembly includes a mounting frame that is slidably installed above the metal mesh conveyor belt in a lifting manner. A buffer roller is rotatably installed between the two opposite inner side walls at the bottom of the mounting frame. An inlet channel allowing fertilizer to pass through is provided between the bottom of the buffer roller and the upper surface of the metal mesh conveyor belt.

[0008] Furthermore, a pulverization motor with an output end extending into the machine base and fixedly connected to the end of one of the pulverization rollers is fixedly installed on the outer side wall of the machine base. Mutually meshing gears are fixedly sleeved on the same ends of the two pulverization rollers.

[0009] Furthermore, two symmetrically distributed support seats are installed on the lower bottom of the machine base, a hopper communicating with the machine base is installed on the top of the machine base, and a notch is formed on the side wall of the hopper.

[0010] Furthermore, the feeding assembly further includes two side plates respectively fixedly installed on the inner side walls of both sides of the notch. Both ends of the driving roller are rotatably installed on the corresponding side plates. The metal mesh conveyor belt is arranged between the two side plates, and the width of the metal mesh conveyor belt is consistent with the distance between the two side plates.

[0011] Furthermore, a feeding motor with an output end fixedly connected to one end of the corresponding driving roller is fixedly installed on the outer side wall of one of the side plates. A number of supporting rollers that are in rolling contact with the metal mesh conveyor belt and have the same height as the driving roller are also rotatably installed between the side plates. A support frame is commonly installed at the bottom of the side plates.

[0012] Furthermore, the buffer adjustment assembly further includes a carrier plate fixedly installed between the two side plates. An electric telescopic rod is fixedly installed at the top end of the carrier plate. The output end of the electric telescopic rod penetrates and extends below the carrier plate and is vertically fixedly connected to the top end of the mounting frame.

[0013] The technical solution provided by the present utility model has the following beneficial effects compared with the known prior art:

[0014] 1. A feeding mechanism is installed at the hopper on the top of the crusher. The large - sized chemical fertilizers are mechanically conveyed through the feeding mechanism. Compared with manual conveyance, the frequency of mechanical conveyance is more stable, providing a prerequisite for uniform crushing operation. In addition, the surface of the metal mesh conveyor belt used in the feeding mechanism is evenly provided with mesh holes. During the transportation of large - granular chemical fertilizers, a small amount of debris can directly fall from the mesh holes of the metal mesh conveyor belt, which can reduce the operation load of the crusher.

[0015] 2. A buffer adjustment assembly is arranged above the feeding mechanism. There is a feeding channel allowing chemical fertilizers to pass between the bottom of the buffer roller and the upper surface of the metal mesh conveyor belt. When a large number of large - granular chemical fertilizers pass through the feeding channel, some large - granular chemical fertilizers will be forced to be intercepted and wait slowly to pass through, thereby realizing the buffered discharge of large - sized chemical fertilizers, making them fall onto the hopper from the metal mesh conveyor belt more evenly and in equal amounts, and not causing problems such as excessive load and idling of the crusher, nor causing uneven amounts of the crushed chemical fertilizers obtained at the outlet end, thus facilitating packaging. Moreover, the height of the buffer roller can be adjusted, that is, the size of the feeding channel between the buffer roller and the metal mesh conveyor belt can be adjusted to conveniently meet different production requirements.

Detailed implementation manners

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0023] The following further describes the present invention with reference to the embodiments.

[0024] Embodiment 1

[0025] Refer to Figures 1-4, which is the first embodiment of the present utility model, discloses a chemical fertilizer crusher, including a machine base 1 and two crushing rollers 11 that are reversely rotatably installed in the machine base 1 and are distributed in a staggered manner. The crushing rollers 11 are rollers with a number of equally spaced crushing discs installed on the surface. The thickness of the crushing discs is the same as the spacing between adjacent two crushing discs, so they are in a zigzag shape. Large pieces of chemical fertilizer can only be crushed and dropped by squeezing through the staggered gaps. The feeding assembly includes two driving rollers 22 rotatably installed above the machine base 1. A metal mesh conveyor belt 23 with a port opposite to the upper cavity opening of the machine base 1 is jointly sleeved on the outer roller walls of the two driving rollers 22. The buffer adjustment assembly includes a mounting frame 33 that is slidably installed above the metal mesh conveyor belt 23 in a lifting manner. A buffer roller 34 is rotatably installed between the two opposite inner side walls at the bottom of the mounting frame 33. An inlet passage allowing chemical fertilizer to pass through is provided between the bottom of the buffer roller 34 and the upper surface of the metal mesh conveyor belt 23. Large pieces of chemical fertilizer with a height lower than the buffer roller 34 are directly removed from the metal mesh conveyor belt 23, while large pieces of chemical fertilizer with a height higher than the buffer roller 34 will be blocked by the buffer roller 34. After waiting for the large pieces of chemical fertilizer below to pass, due to gravity, it will naturally fall, and only when the height is lower than the buffer roller 34 can it be allowed to pass, realizing buffer feeding.

[0026] Embodiment 2

[0027] Referring to Figures 1-4 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that a crushing motor 12 with an output end extending into the machine base 1 and fixedly connected to the end of one of the crushing rollers 11 is fixedly installed on the outer side wall of the machine base 1. Gears that are fixedly sleeved on the same-direction ends of the two crushing rollers 11 and mesh with each other are provided, so as to realize the synchronous but reverse rotation of the two crushing rollers 11. Two symmetrically distributed support seats 13 are installed on the lower bottom of the machine base 1. A hopper 14 communicated with the machine base 1 is installed on the top of the machine base 1. A notch is opened on the side wall of the hopper 14. The feeding assembly further includes two side plates 21 respectively fixedly installed on the two inner side walls of the notch. The two ends of the driving roller 22 are respectively rotatably installed on the corresponding side plates 21. The metal mesh conveyor belt 23 is arranged between the two side plates 21, and the width of the metal mesh conveyor belt 23 is the same as the spacing between the two side plates 21, so as to prevent a small amount of chemical fertilizer debris from falling into the gap between the metal mesh conveyor belt 23 and the side plates 21 during the feeding process. An upper feeding motor 24 with an output end fixedly connected to one end of the corresponding driving roller 22 is fixedly installed on the outer side wall of one of the side plates 21. A number of support rollers 25 that are in rolling contact with the metal mesh conveyor belt 23 and have the same height as the driving roller 22 are also rotatably installed between the side plates 21 to improve the stability of the metal mesh conveyor belt 23 when bearing large pieces of chemical fertilizer. A support frame 26 is jointly installed at the bottom of the side plates 21. The buffer adjustment assembly further includes a carrier plate 31 fixedly installed between the two side plates 21. An electric telescopic rod 32 is fixedly installed at the top end of the carrier plate 31. The output end of the electric telescopic rod 32 penetrates and extends below the carrier plate 31 and is vertically fixedly connected to the top end of the mounting frame 33.

[0028] The remaining structure is the same as that of Embodiment 1.

[0029] The working process of the present utility model is as follows:

[0030] First, place the large pieces of chemical fertilizer on the upper surface of the metal mesh conveyor belt 23, start the feeding motor 24, drive the corresponding driving roller 22 to rotate, and cooperate with another driving roller 22 to realize the conveyance of the metal mesh conveyor belt 23, that is, the large pieces of chemical fertilizer. During the conveyance process, a small amount of debris carried on the large pieces of chemical fertilizer will directly fall through the mesh holes opened on the metal mesh conveyor belt 23, initially reducing the working load of the crushing rollers 11.

[0031] Second, according to the type of chemical fertilizer and the volume of the large pieces of chemical fertilizer, adjust the size of the chemical fertilizer feeding channel. Specifically, start the electric telescopic rod 32 to drive the mounting frame 33, that is, the buffer roller 34, to lift and adjust the height, thereby adjusting the size of the chemical fertilizer feeding channel. When the large pieces of chemical fertilizer roll into contact with the buffer roller 34 relatively, the large pieces of chemical fertilizer lower than the height of the buffer roller 34 directly pass through from the upper surface of the metal mesh conveyor belt 23, while the large pieces of chemical fertilizer with a height higher than that of the buffer roller 34 will be blocked by the buffer roller 34 and wait to fall and be conveyed after the large pieces of chemical fertilizer in front are fed, realizing buffered feeding.

[0032] Finally, the large pieces of chemical fertilizer falling from the metal mesh conveyor belt 23 will fall into the two crushing rollers 11 through the hopper 14. Start the crushing motor 12 to drive the two crushing rollers 11 to rotate in opposite directions, and then drive the large pieces of chemical fertilizer to move towards the centers of the two crushing rollers 11, completing the extrusion and crushing of the large pieces of chemical fertilizer.

[0033] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the various embodiments of the present utility model.
