[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0021] The following describes a forage crushing device for mutton sheep breeding provided by some embodiments of the present invention in conjunction with the accompanying drawings.

[0022] Embodiment 1:

[0023] Combine Figure 1-4 As shown, the utility model provides a forage crushing device for mutton breeding, including a body mechanism, a transmission mechanism and a crushing mechanism. The body mechanism includes a main shell 110, a discharge hopper 120 arranged at the top of the main shell 110, a feed roller 130 installed in the middle of the chamber of the main shell 110, a guide roller 140 arranged below the feed roller 130, a cutting groove 150 opened in the middle of the chamber of the main shell 110, and a discharge port 170 for unloading located directly below the cutting groove 150. A shielding cover 180 that fits the discharge hopper 120 is provided on the top of the main shell 110, and a material sorting rod is installed on the side wall of the discharge hopper 120. The transmission mechanism includes a protective shell 210 fixedly installed on the outside of the main shell 110, a motor 220 installed at a corner of the protective shell 210, and a motor connected to the output end of the motor 220. The driving gear 230 is connected, the first-stage transmission component 240 is transmission-connected to the driving gear 230, the second-stage speed-increasing gear set 250 is meshed with the end of the first-stage transmission component 240, the third-stage speed-increasing gear 260 is meshed with the second-stage speed-increasing gear set 250, and the final-stage transmission component 270 is transmission-connected to the third-stage speed-increasing gear 260. The gear teeth of the second-stage speed-increasing gear set 250 are equal to those of the third-stage speed-increasing gear 260, and the diameter of the second-stage speed-increasing gear set 250 is greater than the diameter of the third-stage speed-increasing gear 260. The crushing mechanism includes a half-tooth gear 310 coaxially connected to the final-stage transmission component 270, a reciprocating plate 320 meshed with the half-tooth gear 310, and a cutter 330 fixedly connected to one end of the reciprocating plate 320. The number of the cutters 330 is two groups of four, and the cutters 330 in a group are cut into each other.

[0024] Specifically, the power of the driving gear 230 is transmitted to the half-tooth gear 310 by using the first-stage transmission component 240, the second-stage speed-increasing gear set 250, the third-stage speed-increasing gear 260 and the final-stage transmission component 270, so that the cutter 330 obtains the power to move repeatedly. The two cutters 330 are engaged with each other to chop the grass without the need for an additional power mechanism, and the cutting rate of the cutter 330 matches the conveying rate of the feed roller 130, so that the upper cutter 330 will cut grass of equal length, limiting the upper limit length of the grass, ensuring its quality, facilitating subsequent processing, and improving the practicality of the device.

[0025] In addition, a sliding groove 160 is provided at the position where the crushing mechanism is installed in the main shell 110, and an auxiliary discharge groove 340 that passes through to the discharge port 170 is provided at the position of the sliding groove 160 near the cutting groove 150. As the cutting proceeds, grass debris will inevitably enter the front end of the sliding groove 160. At this time, the auxiliary discharge groove 340 is connected with the discharge port 170 to discharge the grass debris that has entered the front end of the sliding groove 160, thereby avoiding residue inside the device and causing mold and the like, thereby improving the safety of the device.

[0026] The working principle and usage process of the present invention are as follows: first, start the device, remove the shielding cover 180, place the grass to be crushed into the discharge hopper 120, and when passing through the sorting rod, the grass is straightened and vertically captured by the feed roller 130, and then vertically enters the cutting groove 150 under the guidance of the guide roller 140. At this time, the cutters 330 cut the grass into pieces by mutual engagement. The two sets of cutters 330 can chop the grass more thoroughly, and finally the crushed grass can be discharged through the discharge port 170.

[0027] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
