Description

Technical Field

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

[0002] In animal husbandry, when feeding herbivores, bundles of hay need to be cut and crushed to facilitate the addition of feed to the hay in later feedings, forming a mixed feed for the animals. This usually requires the use of a hay crushing device to cut and crush the hay.

[0003] For example, Chinese Patent Publication No. CN221532193U discloses a forage crushing device, including a crushing box and fixing screws. A base plate is fixedly installed at the bottom of the crushing box, and a feed inlet is opened on the top surface of the crushing box. A protective frame is fixedly installed on the feed inlet, and a discharge outlet is opened on the base plate. A discharge pipe is fixedly installed on the discharge outlet. This utility model achieves multi-stage crushing of forage through a first crushing mechanism and a second crushing mechanism, which can ensure that the forage is crushed more evenly and thoroughly. This effectively avoids the situation where large-shaped forage is difficult for livestock to digest when feeding them, thus ensuring the growth of livestock. A second motor is installed on a storage box that is slidably installed through the groove of the discharge pipe, and a stirring blade is installed on the second rotating rod on the output shaft of the second motor.

[0004] However, in the above-mentioned scheme, the device is not convenient for separating the moisture inside the hay during use, resulting in a large amount of moisture remaining in the hay after crushing, which affects the subsequent processing of the hay. Utility Model Content

[0024] Please see Figure 1-3 In this embodiment of the present invention, a forage crushing device includes a crushing box 1. A feed nozzle 9 is fixedly connected to the top of the crushing box 1. The top opening of the feed nozzle 9 is larger than its bottom opening, and the feed nozzle 9 communicates with the inside of the crushing box 1. Two first crushing rollers 14 and two second crushing rollers 15 are rotatably connected inside the crushing box 1. The two second crushing rollers 15 are located directly below the two first crushing rollers 14. Multiple blades 10 are fixedly connected to the outer sidewalls of both the two first crushing rollers 14 and the two second crushing rollers 15. The multiple blades 10 on the outer sidewall of each second crushing roller 15 are densely packed with the multiple blades 10 on the outer sidewall of each first crushing roller 14. 14 is connected to the side walls of the two second crushing rollers 15 via a transmission structure. An inclined baffle 2 is fixedly connected inside the crushing box 1. A collection box 17 is fixedly connected to the side wall of the crushing box 1. A discharge port 16 is opened on the side wall of the crushing box 1. The discharge port 16 is connected to the inside of the collection box 17 and the inside of the crushing box 1. One end of the inclined baffle 2 is located at the bottom of the discharge port 16. A filter screen 19 is fixedly connected inside the collection box 17. A drain port 18 is provided on the side wall of the collection box 17. The drain port 18 is located below the filter screen 19. The bottom side wall of the collection box 17 is inclined. The drain port 18 is located at the lowest point of the inclined side wall of the bottom of the collection box 17. The top of the collection box 17 is hollowed out. A squeezing structure is provided on the side wall of the crushing box 1.

[0025] Please see Figure 1-3The transmission structure includes four connecting rods 7, which are fixedly connected to the side walls of two second crushing rollers 15 and two first crushing rollers 14, respectively. One end of each connecting rod 7 passes through the side wall of the crushing box 1 and is rotatably connected to the crushing box 1. Gears 8 are fixedly connected to the outer side walls of each of the four connecting rods 7. Two gears 8 at one end of each of the two first crushing rollers 14 are meshed together, and two gears 8 at one end of each of the two second crushing rollers 15 are meshed together. A transmission wheel 6 is fixedly connected to the side wall of one connecting rod 7 at one end of the first crushing roller 14 and one connecting rod 7 at one end of the second crushing roller 15. The two transmission wheels 6 are connected by a transmission belt 5. A mounting plate 3 is fixedly connected to the side wall of the crushing box 1, and a motor 4 is fixedly connected to the top of the mounting plate 3. The motor 4 transmits power to the crushing box 1. One end of the output shaft is fixedly connected to the side wall of one of the connecting rods 7. When the motor 4 is started, the output shaft of the motor 4 drives one of the connecting rods 7 at one end of the second crushing roller 15 to rotate. The connecting rod 7 drives the other connecting rod 7 to rotate through the gear 8. Through the two transmission wheels 6 and the transmission belt 5, the connecting rod 7 on the side wall of the second crushing roller 15 can drive the connecting rod 7 on the side wall of the first crushing roller 14 to rotate simultaneously when it rotates. When multiple connecting rods 7 rotate, they can drive the two first crushing rollers 14 and the two second crushing rollers 15 to rotate. Under the transmission of the gear 8, the two first crushing rollers 14 and the two second crushing rollers 15 rotate relative to each other. The two first crushing rollers 14 can perform preliminary crushing of the grass, and the two second crushing rollers 15 can perform secondary crushing of the grass.

[0026] Please see Figure 1-2 The extrusion structure includes a fixed plate 11, which is fixedly connected to the side wall of the crushing box 1. An electric telescopic rod 12 is fixedly connected to the bottom of the fixed plate 11. A pressure plate 13 is fixedly connected to the extended end of the electric telescopic rod 12. The pressure plate 13 is located directly above the collection box 17. By activating the electric telescopic rod 12, the electric telescopic rod 12 drives the pressure plate 13 to move downward, so that the pressure plate 13 extrudes the grass in the collection box 17, thereby extruding and separating the moisture in the grass and compacting the grass, so that more grass can be collected in the collection box 17.

[0027] Please see Figure 1-2 The crushing box 1 is made of transparent material, making it easy to see the crushing status of the grass inside.

[0028] The working principle of this utility model is as follows: Grass is poured into the crushing box 1 through the feed nozzle 9. The motor 4 is started, and the output shaft of the motor 4 drives one of the connecting rods 7 at one end of the second crushing roller 15 to rotate. The connecting rod 7 drives the other connecting rod 7 to rotate via a gear 8. Through the two transmission wheels 6 and the transmission belt 5, the connecting rod 7 on the side wall of the second crushing roller 15 rotates, simultaneously driving the connecting rod 7 on the side wall of the first crushing roller 14 to rotate. When multiple connecting rods 7 rotate, they drive the two first crushing rollers 14 and the two second crushing rollers 15 to rotate. Under the transmission of the gear 8, the two first crushing rollers 14 and the two second crushing rollers 15 rotate. The rollers 15 rotate relative to each other. The two first crushing rollers 14 can initially crush the grass, and the two second crushing rollers 15 can crush the grass a second time. The crushed grass falls to the top of the inclined baffle 2 and slides down the inclined side wall of the inclined baffle 2 into the collection box 17. The moisture in the grass can be filtered through the filter screen 19. Then, by activating the electric telescopic rod 12, the electric telescopic rod 12 drives the pressure plate 13 to move downward, so that the pressure plate 13 squeezes the grass in the collection box 17, thereby squeezing and separating the moisture in the grass and compacting the grass, so that more grass can be collected in the collection box 17.
