[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 An embodiment of this utility model is provided: a vehicle-mounted mobile chaff cutter and briquetting machine, including a vehicle body 19 and a cab 1. The cab 1 is located at the front of the vehicle body 19. A chaff pressing chamber 7 is installed at the front top of the vehicle body 19. A crushing chamber 2 is connected to the top of the chaff pressing chamber 7. A crushing motor 5 is installed on the outer wall of the crushing chamber 2. Two sets of crushing rollers 20 are installed inside the crushing chamber 2. A gear ring set 21 is sleeved at the end of the crushing rollers 20. The output shaft of the crushing motor 5 drives the crushing rollers 20 to rotate relative to each other through the gear ring set 21. An air duct 4 is connected to the top of the crushing chamber 2. A negative pressure fan 3 is installed at the bottom of the air duct 4. A suction channel 8 is installed at the bottom of the negative pressure fan 3. A conveyor belt 10 is installed on one side of the vehicle body 19. The suction channel 8 is located above the conveyor belt 10. A storage bin 11 is installed at the rear of the vehicle body 19. Specifically, such as Figure 1 and Figure 3 As shown, after the hay is piled on the conveyor belt 10, the negative pressure fan 3, a DF-4 type high-pressure centrifugal fan, is turned on. After being powered on, the impeller rotates at high speed, forming a negative pressure area between the suction channel 8 and the crushing chamber 2. Under its suction, the hay is drawn from the suction channel 8 through the air duct 4 into the crushing chamber 2. The crushing motor 5, a Y90S-4 type, is started. After the crushing motor 5 is started, its output shaft drives the gear ring group 21 to rotate. The gear ring group 21 is meshed with two sets of crushing rollers 20, driving the two sets of crushing rollers 20 to rotate synchronously in opposite directions. The rolling blades quickly cut and shred the hay and guide it into the pressing chamber 7. The entire hay-chopping process is continuous and smooth, does not rely on external power supply, and is suitable for on-site pressing of hay in agricultural cooperatives or pasture bases.

[0018] A shaping pipe 6 is installed at the front of the inner side of the straw pressing chamber 7. A pressure cylinder 23 is fixed on the outer wall of one side of the shaping pipe 6. A pressure plate 22 is fixedly connected to the movable end of the pressure cylinder 23. A hydraulic system 9 is installed at the rear of the straw pressing chamber 7. Two sets of hydraulic rods 25 are installed at the hydraulic system 9. The hydraulic rods 25 pass through the rear of the straw pressing chamber 7 and are fixedly connected to a push plate 24. Specifically, such as Figure 1 and Figure 4 As shown, after the chopped grass falls into the pressing chamber 7, the hydraulic system 9 drives two sets of hydraulic rods 25 to perform linear reciprocating motion. The hydraulic system 9 consists of a built-in oil tank, gear pump, and reversing valve. The motor drives the oil pump to press hydraulic oil into the hydraulic rods 25, realizing the reciprocating motion of the hydraulic piston, which pushes the push plate 24 to press the grass back and forth. The system is equipped with an overflow valve to regulate the pressure. The push plate 24 connected to the tail end of the hydraulic rod 25 continuously squeezes the chopped grass towards the front of the pressing chamber 7. When the grass accumulates to the set compaction length, the pressure cylinder 23 is activated. Its output end pushes the pressing plate 22 to compress the grass into a high-density cuboid from the side of the pressing chamber 7 and pushes it out of the plastic tube 6 outlet. The workers then wrap and pack the grass on the other side of the vehicle body 19 to reduce labor intensity.

[0019] Both sides of the rear of the vehicle body 19 are equipped with screws 13. Threaded seats 16 are sleeved on the outside of the screws 13. A guide frame 14 is set on the side of the screws 13 near the rear of the vehicle. A lifting platform 15 is sleeved on the outside of the guide frame 14. The threaded seats 16 are welded and fixed to the lifting platform 15. The screws 13 are arranged on both sides of the lifting platform 15, and the two sets of screws 13 are symmetrically distributed about the central axis of the lifting platform 15. An adjustment motor 12 is installed on one side of the vehicle body 19. The adjustment motor 12 is a YS7124 type gear reduction motor, suitable for controlling the slow and heavy-load lifting of lifting platforms. A gear set 18 is installed on the output shaft of the adjustment motor 12, and the adjustment motor 12 drives the screws 13 to rotate through the gear set 18. Specifically, such as Figure 1 and Figure 2 As shown, after the grass blocks are packed, the regulating motor 12 is started, which drives the screw 13 to rotate through the gear set 18. The screw 13 is threadedly engaged with the threaded seat 16, pushing the lifting platform 15 to rise vertically along the guide frame 14. When the lifting platform 15 rises to be level with the lower edge of the storage bin 11, the workers easily push the grass blocks into the storage bin 11 and stack them neatly. After stacking, the regulating motor 12 is driven again to lower the lifting platform 15 back to its original position.

[0020] The bottom end of the guide frame 14 is movably connected to the telescopic support leg 17. The support leg 17 is fixed by a pin to extend its length from the bottom of the guide frame 14. The lifting platform 15 is located behind the vehicle body 19. The lifting platform 15 is a flip-up steel plate. The width of the lifting platform 15 is adapted to the size of the storage bin 11. Specifically, such as Figure 1 and Figure 2As shown, the lifting platform 15 is a flip-type steel plate structure. When not in use, it can be flipped and folded to the rear of the vehicle body 19, saving space and facilitating transportation. The bottom of the guide frame 14 is equipped with support legs 17, which are pin-adjustable structures that can adjust the support height according to the terrain, eliminating the need for scaffolding and manual delivery.

[0021] Working principle: After the hay accumulates on the conveyor belt 10, the negative pressure fan 3 starts, forming a negative pressure area between the suction channel 8 and the crushing chamber 2. Under the action of suction, the hay is sucked into the crushing chamber 2 through the air duct 4. After the crushing motor 5 starts, its output shaft drives the gear ring assembly 21 to rotate. The gear ring assembly 21 drives the two sets of crushing rollers 20 to rotate synchronously in opposite directions. The rolling teeth on the crushing rollers 20 cut the hay into fragments, which fall directly into the pressing chamber 7. The hydraulic system 9 in the pressing chamber 7 starts, driving the two sets of hydraulic rods 25 to perform reciprocating linear motion, pushing the push plate 24 to continuously squeeze the hay fragments towards the front end of the pressing chamber 7. When the hay is compacted to the set length, the pressure cylinder 23 is activated, and its movable end drives the pressure plate 22 to push the hay out laterally from the side. The shaped pipe 6 is extruded and finally pushed out from the outlet to form high-density grass blocks, which are convenient for subsequent packaging. The formed and packaged grass blocks are placed on the lifting platform 15. The regulating motor 12 is started, and the drive gear set 18 drives the screws 13 on both sides to rotate. The screws 13 push the lifting platform 15 vertically up along the guide frame 14 through the threaded seat 16. When the lifting platform 15 is raised to be level with the lower edge of the storage bin 11, the workers can push the grass blocks into the storage bin 11 for stacking. After stacking is completed, the lifting platform 15 is lowered back to its original position and enters the next round of work. The lifting platform 15 is a flip-up steel plate structure. When not in operation, it can be flipped and folded up to the rear of the vehicle body 19. The bottom of the guide frame 14 is equipped with support legs 17. The support length can be adjusted by the pin to adapt to different terrains.
