Description

Technical Field

[0001] The invention belongs to the technical field of pulverizing devices, and in particular relates to a high-efficiency pulverizing device for feed processing. Background Art

[0002] In the feed processing industry, crushing is a crucial link. The effect of the crushing device directly affects the quality and palatability of the feed and the digestion and absorption efficiency of the animal. For example, the public announcement number: CN118287225A discloses a high-efficiency crushing device for feed processing. However, due to the wide range of sources and types of feed, the particle sizes of different types of feed vary significantly.

[0003] At present, in the process of feed crushing, the larger the particles of the feed, the greater the internal binding force of the material that needs to be overcome to crush it to a certain target particle size, which requires the crushing motor to output a larger power; conversely, the smaller the particles of the feed, the smaller the power required by the crushing motor when crushed to the same target particle size; however, most of the existing feed crushing devices lack intelligent recognition and adjustment mechanisms, and are unable to automatically identify the particle size of the input feed and adjust the power of the crushing motor according to actual conditions. As a result, in the actual production process, whether it is facing large or small particles of feed, the crushing motor runs at a fixed or empirically set power, resulting in energy waste and increased production costs.

[0004] On the other hand, even for feeds of the same particle size, if a smaller particle size is to be obtained after grinding, the grinding motor needs to provide more energy to overcome the stronger intermolecular forces inside the material, which means that the power consumed by the grinding motor will increase significantly, causing energy waste and increasing production costs.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. By arranging a multi-stage filter and a feed detection mechanism in the feed hopper, when different kinds of feed fall on the surface of the multi-stage filter, they first contact the upwardly inclined end of the multi-stage filter. As the feed rolls on the surface of the multi-stage filter and passes through filter mesh holes of multiple specifications in turn, feeds of different particle sizes can be automatically screened. The fallen feed will fall on the top of the feed detection mechanism accordingly. The feed detection mechanism then feeds back an electrical signal to the PLC controller, and the power of the crushing motor is controlled by the PLC controller accordingly. The power of the crushing motor can be adaptively controlled according to the size of the feed particles. The larger the feed particles, the greater the power of the crushing motor controlled by the triggered feed detection mechanism; the smaller the feed particles, the smaller the power of the crushing motor, thereby avoiding energy waste and reducing production costs.

[0023] 2. Through the hydraulic cylinder, push rod, crushing seat and variable resistance mechanism, during the crushing process, by adjusting the extension length of the hydraulic cylinder, the push rod drives the crushing seat to move, and the moving distance is adjustable, so that the distance between the crushing roller and the crushing seat can be adjusted, and then the variable resistance mechanism is used to further perform secondary adaptive adjustment on the power of the crushing motor, automatically adjust the power according to the required target particle size, more accurately match the crushing requirements of different feeds, and reduce unnecessary energy consumption.

[0024] 3. The dust suppression mechanism can effectively handle the dust generated during the crushing process. The vacuum cleaner sucks in and handles the dust generated by the crushing through the telescopic bellows and the dust suction holes at the bottom of the crushing seat to prevent the dust from being discharged with the feed and causing environmental pollution. Moreover, the dust suppression mechanism can automatically adjust the power of the vacuum cleaner according to the target particle size of the feed crushing. The smaller the target particle size, the more dust is generated, the greater the power of the vacuum cleaner, and the better the suction effect. On the contrary, the power is reduced to avoid energy waste, thus achieving energy saving while ensuring a clean production environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] like Figure 1-Figure 6As shown, a high-efficiency crushing device for feed processing includes a bracket 1, a shell 2, a crushing motor 3, a large pulley 4, a crushing roller 5, a small pulley 6 and a belt.

The large pulley 4 and the small pulley 6 are connected by belt transmission. A discharge pipe 19 is arranged at the bottom of the shell 2, and a receiving box 20 is fixedly arranged at the bottom of the bracket 1 and below the discharge pipe 19. When the crushing motor 3 works according to the set power, it can drive the large pulley 4 to rotate, and the large pulley 4 drives the small pulley 6 to rotate through the transmission belt 7, so that the crushing roller 5 rotates inside the shell 2 and performs a crushing operation, and the crushed feed automatically falls into the inside of the discharge pipe 19, and then falls and is collected in the inside of the receiving box 20, and also includes:

[0034] The feed hopper 8 is fixedly arranged on the top of the shell 2. The top of the feed hopper 8 adopts a closed structure, and a feed port 21 is arranged on one side of the feed hopper 8. Such a design can reduce the small amount of dust generated during the screening process from being scattered outward. A multi-stage filter screen 9 is fixedly arranged inside the feed hopper 8 at an angle.

[0035] A plurality of feed detection mechanisms 10 are fixedly arranged inside the feed hopper 8, and the plurality of feed detection mechanisms 10 are distributed and arranged correspondingly to different mesh positions of the multi-stage filter screen 9. The feed detection mechanism 10 includes a detection box 101 fixedly arranged on the inner wall of the feed hopper 8, a first slider 102 is vertically slidably arranged inside the detection box 101, a spring 103 is fixedly arranged between the bottom of the first slider 102 and the bottom of the detection box 101, an extrusion rod 104 is fixedly arranged on the top of the first slider 102, the upper end of the extrusion rod 104 extends to the top of the detection box 101 and is fixedly arranged with an extrusion plate 105, and the extrusion plate 10 5 is inclined, and the area of ​​the squeezing plate 105 is smaller than the area of ​​each level of the multi-level filter screen 9. A fixing seat 106 is fixedly provided on the inner wall of the detection box 101 and located below the slider. A touch switch 107 is fixedly provided on the top of the fixing seat 106. When the feed falls on the surface of the squeezing plate 105 corresponding to the lower part, a downward impact force can be exerted on the squeezing plate 105, so that the squeezing plate 105 drives the squeezing rod 104 to move downward. When the squeezing rod 104 moves downward, it drives the first slider 102 to overcome the elastic force of the first spring 103 and move downward until the bottom of the first slider 102 contacts the button of the touch switch 107.

[0036] The crushing seat 11 is arranged inside the shell 2, and the crushing seat 11 is located on one side of the crushing roller 5. An L-shaped fixing plate 12 is fixedly provided on the outer side wall of the shell 2, and a hydraulic cylinder 13 is fixedly provided on the side wall of the L-shaped fixing plate 12. A push rod 14 is fixedly provided at the movable end of the hydraulic cylinder 13. The end of the push rod 14 away from the hydraulic cylinder 13 extends to the inside of the shell 2 and is fixedly connected to the side wall of the crushing seat 11. The extension of the hydraulic cylinder 13 can drive the push rod 14 to move inside the shell 2, so that the end of the push rod 14 pushes the crushing roller 5 to move in the direction of the crushing roller 5, and the distance between the crushing roller 5 and the crushing seat 11 can be adjusted; the crushing seat 11 adopts a blade-shaped structure, and a telescopic shielding piece 18 is fixedly provided on the top of the crushing seat 11, and the end of the telescopic shielding piece 18 away from the crushing seat 11 is fixedly connected to the inner side wall of the shell 2. During the movement of the crushing seat 11, the distance between the inner wall of the shell 2 will increase, and the telescopic shielding piece 18 can block this gap to prevent feed from entering, thereby improving the crushing effect.

[0037] The variable resistance mechanism 15 is fixedly arranged inside the L-shaped fixed plate 12, and the variable resistance mechanism 15 is connected to the rod wall of the push rod 14. The variable resistance mechanism 15 includes a warehouse body 151 fixedly arranged on the L-shaped fixed plate 12, and a second slider 152 is provided inside the warehouse body 151 for horizontal sliding. A connecting rod 153 is fixedly arranged on one side of the second slider 152. The end of the connecting rod 153 away from the second slider 152 extends to the outside of the warehouse body 151 and is fixedly connected to the rod wall of the push rod 14. A resistor rod 154 is fixedly arranged inside the warehouse body 151 for horizontal sliding. A conductive sleeve 155 is fixedly arranged inside the second slider 152, and the conductive sleeve 155 is slidably connected to the resistor rod 154. The push rod 14 will drive the connecting rod 153 to move together during the movement, so that the end of the connecting rod 153 drives the second slider 152 to move inside the warehouse body 151, and the second slider 152 drives the conductive sleeve 155 to move on the resistor rod 154 when moving, so that the resistance value of the resistor rod 154 connected to the circuit is reduced.

[0038] The dust suppression mechanism 16 is arranged on the outer wall of the shell 2 and the inside of the crushing seat 11. The dust suppression mechanism 16 includes a dust collector 161 fixedly arranged on the outer side wall of the shell 2. A telescopic bellows 162 is fixedly arranged at the input end of the dust collector 161, and the end of the telescopic bellows 162 away from the dust collector 161 is fixedly connected to the crushing seat 11. The crushing seat 11 adopts a hollow structure, and a plurality of evenly distributed dust suction holes 163 are opened at the bottom of the crushing seat 11. When the dust collector 161 is working, the telescopic bellows 162 sucks air into the inside of the crushing roller 5, so that a negative pressure is generated inside the crushing seat 11, so that the dust gas generated during the crushing process can be sucked into the inside of the crushing seat 11 through the dust suction holes 163 at the bottom, and then sucked into the inside of the vacuum cleaner 161 through the telescopic bellows 162 for treatment, so as to avoid the phenomenon that dust is discharged along with the feed and causes environmental pollution.

[0039] The PLC controller 17 is fixedly arranged on the side wall of the L-shaped fixing plate 12 , and the grinding motor 3 , the feed detection mechanism 10 , the variable resistance mechanism 15 and the dust suppression mechanism 16 are all electrically connected to the PLC controller 17 .

[0040] The operating principle of the present invention is described as follows: the staff transports the feed to the inside of the feed port 21 through the conveying device, so that the feed falls into the inside of the feed port 21. When the feed falls, it first contacts the upwardly inclined end of the multi-stage filter 9. As the feed rolls on the surface of the multi-stage filter 9 and passes through filter mesh holes of multiple specifications in sequence, when the feed rolls to the filter mesh hole of the appropriate size, it will automatically fall, thereby automatically completing the screening of different types of feed. When different types of feed fall on the surface of the corresponding squeezing plate 105 below, it can cause the squeezing plate 105 to move. The impact force under the pressure makes the squeezing plate 105 drive the squeezing rod 104 to move downward. When the squeezing rod 104 moves downward, it drives the first slider 102 to overcome the elastic force of the first spring 103 and move downward until the bottom of the first slider 102 contacts the button of the touch switch 107. When the touch switch 107 is triggered, it will feedback an electrical signal to the PLC controller 17. [The touch switch 107 is mechanical, relying on the internal reed and contact action. It is normally open or normally closed when not triggered. When triggered, the contact changes state to make the circuit conductive, and the electrical signal formed by the current is transmitted to the PLC controller 17 through the line. The PLC controller 17 controls the grinding motor 3 to work at a certain power according to the preset program. At this time, the initial power setting of the grinding motor 3 is completed. [Since the mesh diameters of the multi-stage filter 9 are set in increasing order from left to right, different types of feeds fall after being screened by the meshes of the multi-stage filter 9. Here, the feed detection mechanism 10 under the multi-stage mesh controls the grinding motor 3 to work at different powers accordingly, and the power of the grinding motor 3 is increased from left to right by triggering the multiple feed detection mechanisms 10.] When the grinding motor 3 works at the set power, it can bring The large pulley 4 is driven to rotate, and the large pulley 4 drives the small pulley 6 to rotate through the transmission belt 7, so that the crushing roller 5 rotates inside the housing 2 and cooperates with the crushing seat 11, which can ensure that the feed passes through the crushing seat 11 and the crushing roller 5 for crushing operation, and the crushed feed falls through the discharge pipe 19 and is collected in the receiving box 20. The whole process can adaptively control the power of the crushing motor 3 according to the particle size of different types of feed. The larger the feed particles, the greater the power of the crushing motor 3, and the smaller the feed particles, the smaller the power of the crushing motor 3, thereby avoiding energy waste and reducing production costs.

[0041] After different types of feed are identified and the initial power setting of the crushing motor 3 is completed, the PLC controller 17 will also control the hydraulic cylinder 13 to work. The extension of the hydraulic cylinder 13 can drive the push rod 14 to move toward the inside of the shell 2, so that the end of the push rod 14 pushes the crushing roller 5 to move in the direction of the crushing roller 5, so that the distance between the crushing roller 5 and the crushing seat 11 can be adjusted, so that the target crushing particle size of different types of feed can be adjusted. As the push rod 14 moves, and the degree of movement is different, the push rod 14 will drive the connecting rod 153 to move together, so that the end of the connecting rod 153 drives the second slider 152 to move inside the warehouse body 151, and the second slider 152 drives the conductive sleeve 155 to move on the resistance rod 154 when moving, so that the conductive sleeve 155 can move on the resistance rod 154. The resistance of the resistance rod 154 connected in the circuit decreases, and at the same time, the current connected in the same circuit between the resistance rod 154 and the grinding motor 3 increases, thereby increasing the power of the grinding motor 3, and completing the second power setting for the grinding motor 3 [the smaller the particle size of the feed to be crushed, the smaller the distance between the grinding roller 5 and the grinding seat 11, and the greater the distance the push rod 14 is pushed, the greater the distance the connecting rod 153 drives the second slider 152 to move, thereby making the conductive sleeve 155 move on the resistance rod 154. The greater the resistance of the resistance rod 154 is, the greater the automatic increase in the power of the grinding motor 3, and the whole process can adaptively adjust the power of the grinding motor 3 according to the required target particle size], avoiding energy waste and reducing production costs;

[0042] During the crushing process, dust is generated due to the cooperation between the crushing roller 5 and the crushing seat 11. When the crushing motor 3 is turned on, the PLC controller 17 will also control the vacuum cleaner 161 to start working. The vacuum cleaner 161 sucks air from the inside of the crushing roller 5 through the telescopic bellows 162, so that negative pressure is generated inside the crushing seat 11, so that the dust gas generated during the crushing process can be sucked into the inside of the crushing seat 11 through the dust suction hole 163 at the bottom, and then sucked into the inside of the vacuum cleaner 161 through the telescopic bellows 162 for treatment, thereby avoiding the phenomenon that dust is discharged with the feed and causes environmental pollution;

[0043] When the same type of feed is crushed, the smaller the target particle size is, the greater the dust generated [smaller crushing particle size means that the particles are easier to disperse. During the crushing operation, these fine particles are more easily driven by the airflow, forming the phenomenon of dust flying]. The smaller the crushing target particle size is, the smaller the required spacing between the crushing roller 5 and the crushing seat 11 is, and the greater the distance the push rod 14 is pushed. At this time, the connecting rod 153 drives the second slider 152 to move a greater distance, thereby making the conductive sleeve 155 move a greater distance on the resistance rod 154 and gradually reducing the resistance value of the resistance rod 154. At this time, the current connected to the same circuit of the vacuum cleaner 161 and the resistance rod 154 is greater, which can increase the power of the vacuum cleaner 161 and improve the dust suction effect. Conversely, the larger the target particle size is, the smaller the dust generated is. At this time, the power of the vacuum cleaner 161 can be reduced to avoid energy waste.

[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 substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
