Feed generally refers to the food of animals raised in agriculture or animal husbandry. When feeding cattle and sheep, ruminant feed often needs to be ground. Feed grinding is an important part of feed processing. The ground feed can be better absorbed.

[0003] When grinding feed, the existing ruminant feed grinding device generally grinds the feed directly through a grinding roller, and the ground feed is taken out from the device. Although some devices will install a crushing roller in advance to crush the feed, and some devices will screen the qualified feed by shaking and screening, in this process, since the crushing roller needs to be driven by a motor, and the shaking and screening of the device also requires other motors to drive, at least two or more motors are required to grind the feed, resulting in poor utilization efficiency of the motors, which will increase the cost of the device, and the unqualified feed after screening often needs to be taken out manually, and then the taken out feed is poured into the device for repeated grinding, and it is difficult to continue grinding the unqualified feed in time, resulting in poor grinding efficiency.

[0024] When the ruminant feed is ground by the device, the ruminant feed is added into the grinding box 1 through the feed hopper 2. During this process, the drive motor 6 works and drives the drive shaft 7, the synchronous gear 20 and the two crushing rollers 4 to rotate together. Therefore, the two crushing rollers 4 are driven to work at the same time by the operation of the drive motor 6, which is beneficial to the early crushing of the ruminant feed, thereby improving the efficiency of subsequent grinding of the feed.

[0025] In this embodiment, a rotating shaft 9 is provided below the crushing roller 4, and arc-shaped push blocks 10 are fixed on the left and right sides of the upper end of the rotating shaft 9. A screening box 3 that passes through from top to bottom is provided below the rotating shaft 9, and a screen plate 16 is fixed at the lower end of the screening box 3, and a grinding roller 18 is provided at the upper end of the screen plate 16. A grinding drive assembly is provided above the screen plate 16, and the grinding drive assembly includes a forward and reverse motor 12, a screw rod 15, a sliding block 13 and a guide rod 14. The forward and reverse motor 12 is fixed to the outside of the screening box 3, one end of the screw rod 15 is connected to the power end of the forward and reverse motor 12, and the other end of the screw rod 15 rotates to penetrate into the screening box 3, the sliding block 13 is threadedly sleeved on the outer periphery of the screw rod 15, and the guide rod 14 is fixed in the screening box 3.

[0026] When the feed is crushed, the crushed feed will fall into the screening box 3. At this time, the forward and reverse motors 12 work and drive the screw rod 14 to rotate back and forth. The screw rod 14 will drive the sliding block 13 to slide back and forth along the guide rod 15. The grinding roller 18 is set to contact the upper end surface of the screen plate 16. Therefore, the grinding roller 18 will grind the feed on the screen plate 16 back and forth, which is conducive to obtaining qualified ruminant feed.

[0027] In this embodiment, a rotating shaft 9 is provided below the crushing roller 4, and arc-shaped push blocks 10 are fixed on the left and right sides of the upper end of the rotating shaft 9. A screening box 3 that passes through from top to bottom is provided below the rotating shaft 9, and arc-shaped impact blocks 11 are fixed on the left and right sides of the upper end of the screening box 3. A screen plate 16 is fixed at the lower end of the screening box 3, and a plurality of springs 17 are connected between the inner wall of the grinding box 1 and the outer wall of the screening box 3. One of the belt gears 8 is fixedly sleeved on the outer periphery of one of the driving shafts 7, and the rotating shaft 9 rotates to the right to pass through the grinding box 1 and the end extends into the protective cover 5.

At the same time, the screening box 3 will compress or stretch the corresponding spring 17, so combined with the elastic force of the spring 17, the screening box 3 and the screen plate 16 will be driven to shake, so as to facilitate the shaking screening of the ground feed through the screen plate 16, effectively ensuring the screening efficiency of the feed, and the screen plate 16 shakes the screening material. During the process, the grinding roller 18 will repeatedly grind the feed on the screen plate 16, and the qualified feed will be normally screened to the bottom end of the grinding box 1 through the screen plate 16, and the qualified feed will be discharged and collected by the discharge pipe 19, and the unqualified feed will continue to be ground on the screen plate 16 until it is qualified and screened.

At the same time, the driving motor 6 drives the driving shaft 7, the belt gear 20 and the two grinding rollers 4 to grind the feed on the screen plate 16 back and forth. The wheel 20, the rotating shaft 9 and the arc-shaped push block 10 rotate together, so the arc-shaped push block 10 will continuously hit the arc-shaped hit block 11 through the arc surface, and the elastic force of the spring 17 will drive the screening box 3 and the screen plate 16 to shake. At this time, the screen plate 16 is used to shake and screen the feed being ground. At the same time, the grinding roller 18 will repeatedly grind the feed on the screen plate 16.
