The third motor drives the rotating shaft 302 to rotate, and the spiral blades 303 convey the straw segments from the collecting hopper 107 to the first mounting shell 206.
As shown in fig. 4, since the two rollers 202 are not at the same height and there is a portion where the sliding blocks 208 block the excess straw segments from touching each other, i.e., the straw segments in one roller 202 are abutted against the sliding blocks 208 on the limiting plate 210 in the other roller 202, the portion of straw segments is prevented from falling into the lower collecting port 214 without being rubbed. The straw section extends out of the first discharging hole 211 and exceeds the first side surface of the limiting disc 210, reaches between the two limiting discs 210, is rubbed with the straw section extending out of the other party, and falls into the collecting opening 214 from the gap between the two limiting discs 210 and is discharged.
When the compactness of the straw sections in one roller 202 is higher, the extrusion force of the straw sections with higher compactness to the sliding block 208 is increased, the limiting disc 210 in the other roller 202 is moved towards the direction close to the collecting hopper 107, the springs 207 corresponding to the limiting discs 210 are stretched, so that the distance between the two limiting discs 210 is increased, the rubbed straw sections are easier to fall off, and the length increase exceeding the end surfaces of the limiting discs 210 does not reduce the strength of the straw sections due to the compactness of the straw sections, and the rubbing of the straw is affected. When the compactness of the straw sections in one roller 202 is smaller, the spacing between the two limiting plates 210 is smaller under the action of the spring 207, so that the straw sections are prevented from falling off without being rubbed.
In other embodiments of a donkey farming straw feed cutting apparatus of the present utility model, the differences from the above embodiments are: the axes of the two rollers 202 in the kneading mechanism are in the same straight line, the limiting component in the kneading mechanism is replaced by two baffle plates, a connecting rod extending radially along the baffle plates is fixedly arranged on each baffle plate, each baffle plate is fixedly arranged at one end, close to the first mounting shell 206, of one roller 202 through the connecting rod, the baffle plates are vertically arranged and concentric with the roller 202, and an annular channel is formed between each baffle plate and the roller 202. The straw segments in two rollers 202 extend from the endless channel and contact the straw segments extending in adjacent rollers 202. The two rollers 202 rotate in opposite directions, and the linear speeds of the straw sections in the two rollers 202 are consistent on the same horizontal line, but the straw sections can be rubbed due to the fact that the linear speeds of the straw sections in the annular channels are large, and the rubbing effect is guaranteed.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
