Description

Technical Field

[0001] The utility model relates to the technical field of particle grinding equipment, in particular to a particle grinder.

Background Art

[0002] A particle grinder is a device that grinds solid materials into particles. It grinds the materials into powder through the grinding device in the grinder, making the particles in a powder state, which is convenient for personnel to process the materials. The particle grinder is mainly used in fields such as fertilizer production and biological particles, which can greatly improve the processing efficiency of the materials. The existing particle grinders are as follows:

[0003] For example, the patent publication number CN209222224U discloses a device for grinding large particles of fertilizer, including a grinding box. A feeding hopper is fixedly connected to the top of the grinding box. Two rotating plates are rotatably connected inside the front side walls of the grinding box and the feeding hopper. A rotating shaft is fixedly connected to the back of the rotating plate. A transmission belt is connected in a transmission manner between the two rotating shafts at the top and between the two rotating shafts at the bottom. One end of the back of the two rotating shafts on the right is respectively fixedly connected to the output shafts of two servo motors. A grinding wheel is fixedly connected to the outside of the rotating shaft. This device for grinding large particles of fertilizer can effectively improve the grinding efficiency of the fertilizer, improve the working efficiency of the fertilizer crushing and grinding device, avoid the situation of different sizes of fertilizer particles, enable the ground fertilizer to be fully and quickly combined with the soil, improve the fertilization efficiency, and enhance the use effect of the fertilizer.

[0004] In the above solution, it mainly crushes the particles by the rotation of the grinding wheels. After the particles are ground, the particles enter the fixed grinding table, and the grinding wheels on the fixed grinding table rotate to grind the fertilizer, so as to achieve the grinding process of the fertilizer. Although the grinding can be realized by this method, since the grinding wheels mainly rely on the driving of the grinding motor, and the grinding motor is fixedly installed on the machine case, when the fertilizer needs to be ground into powders of different thicknesses, the position of the grinding motor cannot be adjusted, and accordingly, the grinding wheels fixedly connected to it cannot be adjusted either. When the grinding wheels cannot be adjusted and the personnel need to grind the particles into different sizes and thicknesses, the non-adjustable grinding wheels cannot process the particles into powders of different thicknesses, and thus it can only grind particles of one thickness, resulting in poor applicability of the equipment to the grinding of particle thickness.

[0026] Such as Figures 1 to 3 , a particle grinder, comprising: a housing 1, a crushing mechanism 2 provided on the top surface of the housing 1, and a grinding disc 3 that is driven to rotate and connected inside the housing 1 and is disposed opposite to the crushing mechanism 2. The grinding disc 3 is driven by a third motor 23, and the third motor 23 is fixedly connected to the housing 1. By fixedly connecting the output shaft of the third motor 23 to the grinding disc 3, the rotation of the grinding disc 3 can be realized. Before grinding, personnel can put fertilizers into the crushing mechanism 2. The crushing mechanism 2 is mainly composed of two relatively arranged crushing rollers 22 and a fourth motor 24 connected. The crushing rollers 22 are rotatably connected inside the housing 1, and the output shaft of the fourth motor 24 is fixedly connected to the crushing rollers 22. By using the fourth motor 24, the crushing rollers 22 can be driven to rotate, so as to achieve the crushing of fertilizers by the crushing rollers 22;

[0027] After the fertilizers are crushed, the fertilizers will enter the guide plate 7 that is driven to rotate and connected inside the housing 1. The guide plate 7 is used to guide the waste materials so that the fertilizers enter between the grinding plate 5 and the grinding disc 3. Since the grinding disc 3 is conically arranged, a support seat 4 is fixedly connected inside the housing 1. A connecting plate 6 that is driven to slide obliquely along the direction of the grinding disc 3 is slidably connected to the support seat 4. The connecting plate 6 is disposed opposite to the inclined surface of the grinding disc 3. Therefore, when the connecting plate 6 moves, the grinding plate 5 fixedly connected to the connecting plate 6 is driven to move by the movement of the connecting plate 6, so as to adjust the distance between the grinding plate 5 and the grinding disc 3. When the fertilizers enter the gap between the grinding disc 3 and the grinding plate 5 through the guide plate 7, the grinding disc 3 rotates, and the rotation of the grinding disc 3 is used to achieve the grinding of the fertilizers. The grinding surface of the grinding plate 5 corresponds to the shape of the grinding surface of the grinding disc 3.

[0028] Specifically, since a first lead screw 8 is threadedly connected to the support base, one end of the first lead screw 8 is rotatably connected to the connecting plate 6, a first motor 9 is slidably connected to the support base 4, the output shaft of the first motor 9 is fixedly connected to the first lead screw 8, and a telescopic rod 21 is fixedly connected to the support base 4, one end of the telescopic rod 21 is fixedly connected to the connecting plate 6. Therefore, the telescopic rod 21 can limit the connecting plate 6 to prevent it from rotating, and the first motor 9 can drive the first lead screw 8 to rotate, thereby enabling the first lead screw 8 to drive the connecting plate 6 to move.

[0029] Specifically, since a distance sensing block 10 is fixedly connected to the connecting plate 6, a distance sensor 11 is fixedly connected to the support base 4, the distance sensing block 10 and the distance sensor 11 are arranged opposite to each other, a control panel 12 is fixedly connected to the housing 1, the control panel 12 is electrically connected to the distance sensor 11, a second motor 13 is fixedly connected to the housing 1, the output shaft of the second motor 13 is fixedly connected to the guide plate 7, and the second motor 13 is electrically connected to the control panel 12. Therefore, when the connecting plate 6 moves, the distance sensor 11 will sense the distance sensing block 10, transmit a signal to the control panel 12 through the distance sensor 11, and use the control panel 12 to control the second motor 13 to start, thereby realizing the synchronous adjustment of the distance between the grinding plate 5 and the grinding block and the distance of the guide plate 7.

[0030] Specifically, since the guide plate 7 includes a collection box 15 with a top slot 14 and a transmission pipe 16 communicating with the collection box 15, one end of the transmission pipe 16 is close to the gap between the grinding plate 5 and the grinding disc 3, the other end of the transmission pipe 16 away from the grinding disc 3 communicates with the collection box 15, an inclination angle 17 is provided at one end of the slot 14 close to the transmission pipe 16, and the output shaft of the second motor 13 is fixedly connected to the collection box 15. Therefore, the slot 14 guides the fertilizer and guides the fertilizer into the transmission pipe 16 through the inclination angle 17, so that the transmission pipe 16 transports the fertilizer into the gap between the grinding plate 5 and the grinding block, thereby realizing the grinding of the fertilizer.

[0031] Specifically, a conveying plate 18 is fixedly connected to the housing 1 at an inclined angle near the grinding disc 3, and a partition plate 19 is fixedly connected to the housing 1 in the vertical direction. The conveying plate 18 is used to guide the fertilizer, and the partition plate 19 can reduce the fertilizer from entering the other side inside the housing 1.

[0032] Specifically, a storage box 20 is slidably connected inside the housing 1. The storage box 20 is located on one side of the partition plate 19 and one end extends outside the housing 1, and it is mainly used for storing fertilizer.

[0033] Principle of the utility model: The operator imports fertilizers onto the housing 1. By the rotation of the two crushing rollers 22, the fertilizers are crushed in advance. After the fertilizers are crushed, they enter onto the guide plate 7. The guide plate 7 guides the fertilizers into the gap between the grinding plate 5 and the grinding disc 3. At this time, the grinding disc 3 rotates, and the rotation of the grinding disc 3 is used to grind the fertilizers. It is worth mentioning that when the grinding fineness needs to be adjusted, only by sliding the connecting plate 6 to adjust the position between the grinding disc 3 and the grinding plate 5 can the grinding fineness of the fertilizers be adjusted.

[0034] The above embodiments are illustrative of the present utility model and not restrictive thereof. Any simple transformation of the present utility model falls within the protection scope of the present utility model.
