Description

Technical Field

[0001] This utility model relates to the field of fertilizer production technology, and in particular to a fertilizer agglomeration crushing device. Background Technology

[0002] Chemical fertilizers, or simply fertilizers, are fertilizers made by chemical or physical methods that contain one or more nutrients needed for crop growth. They are also called inorganic fertilizers. During the production and processing of chemical fertilizers, they are easily affected by the humidity in the environment, which can lead to caking and affect the after-sales user experience. Before leaving the factory, the pseudo-caking of chemical fertilizers can be crushed and screened to improve the after-sales user experience.

[0003] For example, the utility model disclosed in announcement number CN218689839U discloses a device for crushing agglomerated fertilizer, including a crushing box. Two sliding grooves are opened at the upper port of the crushing box, and a sliding rod is installed in each sliding groove. Slide plates adapted to the sliding grooves are slidably arranged on the two sliding rods. By covering the surface of the motor with a spiral tube, cold water in the water tank is drawn into the spiral tube by a water pump. The cold water passing through the spiral tube absorbs the heat generated by the motor and turns into hot water before returning to the water tank. This allows the heat generated by the motor to be quickly dissipated, reducing the temperature around the motor and extending the service life of the motor.

[0004] However, fertilizers are prone to clumping during storage, mainly due to moisture. The crushing device in the above application does not heat and dry the fertilizer when crushing it. Therefore, the crushing roller is not conducive to fully crushing the fertilizer when crushing it, thus affecting the crushing effect. Therefore, a fertilizer clumping crushing device is proposed to solve the above problems. Utility Model Content

[0021] like Figure 1-5 As shown, the present invention proposes a fertilizer agglomeration crushing device, which includes a crushing chamber 1. The upper end of the crushing chamber 1 is open and the opening is funnel-shaped. The front side of the crushing chamber 1 is fixedly connected to a discharge port 2 and a guide frame 3, and the guide frame 3 is located below the discharge port 2. The crushing chamber 1 is equipped with crushing components 4 for crushing fertilizer.

[0022] In this invention, the crushing component 4 can collect, shake, and dry the fertilizer before crushing to improve the dryness of the fertilizer.

[0023] It should be noted that the discharge port 2 is an inclined device with a higher back and a lower front, through which the fertilizer that has not been completely screened is discharged, and the guide frame 3 is a cone shape with a wider back and a narrower front. The inner bottom wall of the crushing chamber 1 is inclined with a lower front and a higher back, so that the guide frame 3 can guide the fertilizer screened by the crushed parts 4 to be discharged.

[0024] In an optional embodiment, the crushing component 4 includes two support frames 42 symmetrically and slidably connected to the inner wall of the crushing chamber 1. A receiving frame 41 is fixedly connected to each support frame 42, located above the support frames 42. The inner wall of the receiving frame 41 is mesh-like. A ventilation mesh 410 is fixedly connected to the inner side of each support frame 42. A guide plate 43 is fixedly connected to the lower surface of the two support frames 42. A screen 49 is fixedly connected to the lower end of the guide plate 43. A set of crushing rollers 4 is rotatably mounted on the inner wall of the crushing chamber 1, located inside the guide plate 43. 4. The front end of the crushing roller 44 passes through the crushing chamber 1, and a set of crushing rollers 44 are fixedly connected to the end of the crushing chamber 1 with meshing gears 45. The rear side of the crushing chamber 1 is fixedly connected to the crushing motor 411, and the output shaft of the crushing motor 411 is fixed to the rear end of the right crushing roller 44. A drive motor 46 is fixedly installed on one side of the crushing chamber 1, and a rotating shaft 47 located below the screen 49 is rotatably connected to the inner wall of the crushing chamber 1. One end of the rotating shaft 47 is fixedly connected to the output shaft of the drive motor 46, and a set of cams 48 are fixedly connected to the rotating shaft 47. The back of the crushing chamber 1 is provided with an air supply component 5 for conveying hot air into the crushing chamber 1.

[0025] In this embodiment, the fertilizer before crushing can be received by the receiving frame 41 on the support frame 42. The driven motor 46, in conjunction with the cam 48 on the rotating shaft 47, drives the guide plate 43, the support frame 42 and the receiving frame 41 to vibrate. In conjunction with the hot air conveyed into the crushing chamber 1, the fertilizer can be shaken and dried, so that the fertilizer can be put into the crushing roller 44 in a dry state for crushing, thereby improving the crushing effect.

[0026] It should be noted that the support frame 42 is provided with an elastic support member for elastic support; a rectangular groove is opened on the side of the crushing chamber 1 near the support frame 42. The elastic support member includes a guide block 412 that is slidably connected in the rectangular groove, and the side of the support frame 42 near the inner wall of the crushing chamber 1 is fixed to the guide block 412. A guide rod 413 that passes through the guide block 412 is fixedly connected in the rectangular groove, and a spring 414 is fixedly connected between the guide block 412 and the inner side of the rectangular groove. There are four guide blocks 412, and the four guide blocks 412 are arranged in pairs and symmetrically distributed on the two support frames 42, so that the four guide blocks 412, together with the guide rod 413 and the spring 414, elastically support the two support frames 42 in the crushing chamber 1.

[0027] The receiving frame 42 is connected to the support frame 41 at one end, which is conical. The end of the conical end is provided with a discharge port. A solenoid valve is installed at the discharge port of the receiving frame 41. The opening and closing of the solenoid valve can cooperate with the conical end of the receiving frame 41 to discharge the fertilizer received by the receiving frame 41 toward the crushing roller 44. The two support frames 42 are symmetrically distributed on the inner wall of the crushing chamber 1 in an inclined manner, so that the two support frames 42 can stably support the conical end of the discharge frame 41.

[0028] In addition, both the guide plate 43 and the screen 49 are arc-shaped, and both the guide plate 43 and the screen 49 are inclined in a way that is lower in the front and higher in the back. This allows the guide plate 43 to pick up the fertilizer crushed by the crushing roller 44 and guide it to the screen 49. At the same time, the shaking guide plate 43, in conjunction with the screen 49, can shake and screen the fertilizer that has been guided to the screen 49. The fertilizer that has not been screened is discharged along the discharge port 2.

[0029] In an optional embodiment, a rectangular groove is formed on the side of the crushing chamber 1 near the support frame 42. The elastic support includes a guide block 412 that is slidably connected in the rectangular groove. The side of the support frame 42 near the inner wall of the crushing chamber 1 is fixed to the guide block 412. A guide rod 413 that passes through the guide block 412 is fixedly connected in the rectangular groove. A spring 414 is fixedly connected between the guide block 412 and the inner side of the rectangular groove.

[0030] In this embodiment, the fan 55 blows room temperature air into the installation chamber 51 through the connecting pipe 56. After being heated by the heating pipe 54, the air is delivered to the bottom of the crushing chamber 1 through the air supply pipe 53. As the hot air rises, it passes through the ventilation net 410 and the side wall of the support frame 42 in sequence, and heats and dries the fertilizer picked up by the material frame 41.

[0031] In an optional embodiment, the air supply component 5 further includes a collection box 57 slidably connected to the inside of the collection chamber 52, and a filter screen 58 is fixedly connected to the inner bottom wall of the collection box 57. The air inlet end of the fan 55 is connected to the inner bottom wall of the collection chamber 52 through a pipe. A dust suction pipe 59 is connected to the upper surface of the collection chamber 52, with one end penetrating through the crushing chamber 1 and located above the receiving frame 41.

[0032] In this embodiment, the collection chamber 52, together with the filter 58 and the suction pipe 59 on the bottom wall of the collection box 57, can adsorb the collection box 57 to create a negative pressure in its inner cavity when the fan 55 is started and delivers hot air into the crushing chamber 1. Then, the dust raised at the opening of the crushing chamber 1 is adsorbed through the suction pipe 59. The dust adsorbed into the collection chamber 52 is blocked and collected by the filter 58 on the collection box 57, thereby reducing the amount of dust raised.

[0033] The working principle in the above embodiments is as follows: Fertilizer is fed into the crushing chamber 1 through the funnel-shaped opening at the top and falls into the receiving frame 41 of the crushing component 4. The inner wall of the receiving frame 41 is mesh-like, allowing hot air to pass through. The drive motor 46 is started, which drives the rotating shaft 47 to rotate. The cam 48 on the rotating shaft 47 rotates accordingly. The cam 48 periodically contacts the guide plate 43. Since the support frame 42 is elastically connected to the inner wall of the crushing chamber 1 through elastic support members including guide block 412, vertical rod 413 and spring 414, the rotation of the cam 48 forces the support frame 42, the receiving frame 41 and the guide plate 43 to shake up and down as a whole. Activate air supply component 5: Fan 55 draws air from collection chamber 52 and blows it into installation chamber 51 through connecting pipe 56. The air is heated by heating pipe 54 inside installation chamber 51 and then transported to the bottom of crushing chamber 1 through air supply pipe 53. As the hot air rises, it passes through ventilation mesh 410 and the mesh inner wall of receiving frame 41, heating and drying the fertilizer in receiving frame 41. The shaking action ensures uniform heating of the fertilizer, improving drying efficiency. When the blower 55 is working, a negative pressure is generated in the collection chamber 52, which absorbs the dust raised at the opening of the crushing chamber 1 through the dust suction pipe 59. After the dust enters the collection chamber 52, it is blocked and collected by the filter screen 58 in the collection box 57, reducing the dust overflow. After drying, open the solenoid valve at the bottom discharge port of the receiving frame 41. The fertilizer falls through the conical discharge port of the receiving frame 41 into a set of crushing rollers 44. Start the crushing motor 411: the crushing motor 411 drives the right crushing roller 44 to rotate. Through the meshing of the gear 45, the set of crushing rollers 44 rotate relative to each other, squeezing and crushing the fertilizer. The crushed fertilizer falls onto the guide plate 43. Since the guide plate 43 is an inclined arc shape with a lower front and a higher back, the fertilizer is guided to the screen 49. Under the action of shaking, it is continuously driven by the cam 48. The screen 49 screens the fertilizer: small qualified fertilizers fall through the screen 49 and are discharged through the conical guide frame 3 which is wider at the back and narrower at the front; large pieces of fertilizer that are not screened move forward along the screen 49 and are discharged from the discharge port 2 which is inclined with a higher back and a lower front. They may be returned for re-crushing or processed separately. The inner bottom wall of the crushing chamber 1 is inclined with a lower front and a higher back, which helps the fertilizer after screening to flow towards the guide frame 3.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
