The speed of the biofuel conveyor belt 11 is A1, A2, and A3, A1 is the minimum value, and A3 is the maximum value, which can be adjusted according to specific needs. When it is necessary to crush large-sized biofuel, the equipment program first controls the first motor 22 to start, and the speed is V1. The biofuel conveyor belt 11 starts, and the speed is A1. The biofuel conveyor belt 11 rotates slowly. At this time, the staff uses a lifting tool to place the biofuel to be crushed on the biofuel conveyor belt 11, and the biofuel conveyor belt 11 slowly transports it backward to the crushing box 211 for flattening and cutting operations. During the transportation process, the first motor 22 rotates slowly and drives the first pulley 221 to rotate slowly. The first pulley 221 passes The second pulley 222 is driven to rotate slowly by the first conveyor belt 223, and the second pulley 222 drives the cutting drum 43 to rotate slowly. The cutting drum 43 drives the third pulley 28 to rotate during the rotation. The third pulley 28 drives the first gear 271 to rotate slowly through the third conveyor belt 273. The first gear 271 and the second gear 272 are meshed with each other. The two sets of gears drive the two sets of second flattening rollers 42 to rotate slowly.

The two groups of second flattening rollers 42 perform secondary flattening operation on the biofuel to improve the flatness of the biofuel, facilitate subsequent transportation and crushing, and improve production efficiency. After the above flattening operation is completed, the biofuel will be transported backward to the cutting roller 43 for cutting operation. The cutting roller 43 slowly rotates to cut the flattened biofuel into sections, and then rolls it into the conveying plate 45 for backward transportation. When it is necessary to crush the conventional size biofuel, the equipment program first controls the speed of the first motor 22 to be adjusted to V2, and the speed of the biofuel conveyor belt 11 is adjusted to A2. The speed of the biofuel conveyor belt 11 is increased. At this time, the staff uses the lifting tool to place the biofuel to be crushed on the biofuel conveyor belt 11, and the biofuel conveyor belt 11 conveys it backward to the crushing box 211 for flattening and cutting operations. During the conveying process, the first motor 22 rotates and drives the first pulley 221 to rotate.

The cutting drum 43 drives the third pulley 28 to rotate during the rotation. The third pulley 28 drives the first The gear 271 rotates, the first gear 271 and the second gear 272 mesh with each other, and the two sets of gears drive the two sets of second flattening rollers 42 to rotate. During the rotation process, the two sets of second flattening rollers 42 drive the two sets of first flattening rollers 41 to rotate through the transmission chain 24. The two sets of first flattening rollers 41 perform preliminary flattening operations on the biofuel to avoid excessive branches of the biofuel causing it to be stuck in the crushing box 211 and affect subsequent operations. The two sets of second flattening rollers 42 perform secondary flattening operations on the biofuel to improve the flatness of the biofuel, facilitate subsequent transportation and crushing, and improve production efficiency. After the above-mentioned flattening operation is completed, the biofuel will be transported backward to the cutting roller 43 for cutting operation. The cutting roller 43 rotates to cut the flattened biofuel into sections, and then rolls it into the conveying plate 45 for backward transportation; When it is necessary to crush small-sized biofuels, the equipment program first controls the speed of the first motor 22 to be adjusted to V3, and the speed of the biofuel conveyor belt 11 is adjusted to A3. The speed of the biofuel conveyor belt 11 is the largest. At this time, the staff uses the lifting tool to place the biofuel to be crushed on the biofuel conveyor belt 11, and the biofuel conveyor belt 11 conveys it backward to the crushing box 211 for flattening and cutting operations.

During the rotation process, the two sets of second flattening rollers 42 drive the two sets of first flattening rollers 41 to rotate rapidly through the transmission chain 24. The two sets of first flattening rollers 41 perform preliminary flattening operations on the biofuel to avoid excessive branches of the biofuel causing it to be stuck in the crushing box 211 and affect subsequent operations. The two sets of second flattening rollers 42 perform secondary flattening operations on the biofuel to improve the flatness of the biofuel, facilitate subsequent transportation and crushing, and improve production efficiency. After the above-mentioned flattening operation is completed, the biofuel will be transported backward to the cutting roller 43 for cutting operation. The cutting roller 43 rotates rapidly to cut the flattened biofuel into sections, and then rolls it into the conveying plate 45 for backward transportation; During the above operation, the equipment program detects the rotation speeds of the four flattening rollers through the two groups of rotation speed detection seats 26. When the rotation speed of the first motor 22 is V2, the equipment program detects whether the rotation speeds of the four flattening rollers are V2 through the two groups of rotation speed detection seats 26. If < V2, the equipment program determines that there are too many conventional-sized biofuel branches in this batch, and the equipment program controls the rotation speed of the first motor 22 to be adjusted to V1 to prevent the incomplete flattening of the biofuel from affecting the subsequent crushing effect. If > V2, the equipment program determines that there are few conventional-sized biofuel branches in this batch, and the equipment program controls the rotation speed of the first motor 22 to be adjusted to V3, thereby improving the flattening efficiency of the biofuel, which can effectively increase the output of the factory. By using the biofuel conveyor belt 11, the first motor 22 and the equipment program in coordination, the flattening and cutting speeds can be changed according to biofuels of different sizes. When the biofuel to be crushed is large in size, the four sets of flattening rollers are rotated at the minimum speed to slowly flatten the biofuel, while reducing the feeding speed to prevent the branches of the biofuel from being stuck in the crushing box 211. At the same time, the flatness of the biofuel can be improved, which is convenient for subsequent transportation and crushing, thereby improving the production efficiency of the factory, reducing the time required for crushing, avoiding machine damage, and reducing the maintenance cost of the factory. When the biofuel to be crushed is small in size, the four sets of flattening rollers are rotated at the maximum speed to quickly flatten the biofuel, thereby improving the flattening efficiency and the feeding speed, effectively The production efficiency of the factory is improved, and the output of the factory is increased. Through the coordinated use of four sets of flattening rollers, a transmission chain 24, a cutting roller 43 and an equipment program, the cutting speed can be changed according to biofuels of different sizes. While the cutting roller 43 is running, it drives the four sets of flattening rollers to perform preliminary flattening and secondary flattening on the biofuel. While cutting, the biofuel is pretreated to improve subsequent production efficiency. At the same time, the energy consumption of the factory is reduced to achieve the purpose of energy conservation and emission reduction. Through the coordinated use of two sets of speed detection seats 26 and an equipment program, the flattened biofuel can be secondary tested to avoid incomplete flattening due to too many branches of the biofuel, which affects the subsequent production efficiency. At the same time, it can avoid the flattening speed being slow when there are few branches of the biofuel and affecting the production efficiency.

[0020] Crushing operation: After completing the above operations, the equipment program controls the crushing operation. The biofuel after flattening and cutting is transported backwards through the conveying plate 45 to the two groups of crushing rollers 44 for crushing operation. The equipment program sets the speed of the second motor 291 to B1, B2, and B3, B1 is the minimum value, and B3 is the maximum value, which can be adjusted according to specific needs. When the equipment program detects that the speed of the first motor 22 is V1, the equipment program controls the second motor 291 to start, and the speed is B3. The second motor 291 drives the two groups of crushing rollers 44 to rotate rapidly. During the forward rotation of one group of crushing rollers 44, the second conveyor belt 252 drives the other group of crushing rollers 44 to reverse. At this time, the two groups of crushing rollers crush the flattened and cut biofuel, and the crushed biofuel will fall downward from the discharge pipe 212 into the workshop storage device; When the equipment program detects that the speed of the first motor 22 is V2, the equipment program controls the second motor 291 to start, and the speed is B2. The second motor 291 drives a group of crushing rollers 44 to rotate. During the forward rotation, one group of crushing rollers 44 drives another group of crushing rollers 44 to reverse through the second conveyor belt 252. At this time, the two groups of crushing rollers crush the flattened and cut biofuel. The crushed biofuel will fall downward from the discharge pipe 212 into the workshop storage device. When the equipment program detects that the speed of the first motor 22 is V3, the equipment program controls the second motor 291 to start, and the speed is B1. The second motor 291 drives the two groups of crushing rollers 44 to rotate slowly. During the forward rotation, one group of crushing rollers 44 drives the other group of crushing rollers 44 to rotate in the reverse direction through the second conveyor belt 252. At this time, the two groups of crushing rollers crush the flattened and cut biofuels, and the crushed biofuels fall downward from the discharge pipe 212 into the workshop storage device. Through the coordinated use of the second motor 291, two sets of crushing rollers 44 and the equipment program, the crushing speed can be changed according to the different flattening speeds. When flattening large-sized biofuels, the flattening speed is slow, which improves the crushing speed and crushing efficiency, avoids the crushed biofuel particles from having a large impact on subsequent production operations, makes the biofuel crushed more thoroughly, and avoids the residue of large agglomerates. When flattening small-sized biofuels, the flattening speed is fast, which reduces the crushing speed, avoids the crushed biofuel powder from scattering around and affecting the production environment of the workshop.

[0021] Feed dehumidification operation: During the above crushing operation, the equipment program controls the feed dehumidification operation. Heat is generated during the crushing process. At this time, the several groups of heat-conducting rods 312 in the crushing box 211 conduct the heat generated by the crushing to the second ventilation pipe 31. The equipment program controls the fan 32 to start, the electric valve 314 to open, the fan 32 blows the wind into the first ventilation pipe 3, and then blows it out to the transported biofuel. The equipment program sets the temperature value to H1, H2, and H3. H1 is the minimum value and H3 is the maximum value. It can be adjusted according to specific needs. The opening value of the electric fan blade 311 is X1, X2, and X3. X1 is the minimum value and X3 is the maximum value. It can be adjusted according to specific needs. When the equipment program detects that the temperature value is H1 through the temperature sensor 313, the equipment program determines that the crushing box 211 has just started to operate, the internal temperature is low, and there is no need to perform heat recovery operation. The equipment program controls the opening value of the electric fan blade 311 to be X1, and only the cold wind blown by the fan 32 is used to dry and dust the transported biofuel; When the device program detects that the temperature value is H2 through the temperature sensor 313, the device program determines that the crushing box 211 is operating normally, the internal temperature is hot, and the heat recovery operation can be performed. The device program controls the opening value of the electric fan blade 311 to be X2, and opens at a small angle to allow part of the hot air to flow into the first ventilation pipe 3, and then the fan 32 blows the wind into the first ventilation pipe 3, and the hot wind will be blown backwards onto the transported biofuel; When the device program detects that the temperature value is H3 through the temperature sensor 313, the device program determines that the crushing box 211 is operating normally, the internal temperature is high, and the heat recovery operation can be performed. The device program controls the opening value of the electric fan blade 311 to be X3, and the maximum angle is opened to make all the hot air flow into the first ventilation pipe 3, and then the fan 32 blows the wind into the first ventilation pipe 3, and the hot wind will be blown backwards onto the transported biofuel; By using the temperature sensor 313, the electric fan blades 311, several groups of heat conducting rods 312 in conjunction with the equipment program, the blowing and dust removal mode can be changed according to the different recovered heat. When the crushing box 211 runs for a short time, only the cold air blown by the fan 32 is used to air-dry and dust-remove the transported biofuel. When the crushing box 211 runs for a long time, the heat generated during crushing is used to heat the cold air, and then the hot air is used to air-dry and dust-remove. This can prevent the wet biofuel from adhering to the inside of the crushing box 211 after crushing, affecting subsequent production and reducing the cleaning burden of the staff. At the same time, the biofuel can be pre-treated and dust-removed to prevent the sediment on the biofuel from damaging the crushing drum 44, thereby increasing the service life of the machine and reducing the cost of daily maintenance.
