The invention relates to the field of agricultural machinery, and provides a straw picking and smashing assembly which comprises a picking and walking module, a smashing module and a dust removal rotating cage which are sequentially arranged from bottom to top, wherein the picking and walking module comprises an auger shaft and at least one picking shaft, a picking hammer claw is arranged on the peripheral wall of the picking shaft, the smashing module comprises a smashing cutter shaft extending along a first direction, and the outlet of a first fan faces the inlet of the dust removal rotating cage. This application embodiment can pick up, smash the straw in the field through the walking module of picking up, crushing module and the dust removal rotating cage that set gradually to can give the great space that sets up of crushing arbor, can smash the straw into less piece, be convenient for next smash, remove dust, make the straw can reach comparatively clean and kibbling state, can obtain effectual reuse.

In the embodiment shown in fig. 1 and 2, only one picking shaft 11 is arranged in the picking-up traveling module 1, so that the structure is simple, the space is saved, and the maintenance is convenient. Fig. 3 and 4 illustrate another embodiment of the present application, in which two pickup shafts 11 are provided in the pickup walking module 1.

In the embodiments shown in fig. 3 and 4, the arrangement of the picking-up and walking module 1 is different from that of the embodiments shown in fig. 1 and 2. In the embodiment shown in fig. 3 and 4, the pickup walking module 1 includes two pickup shafts 11, the two pickup shafts 11 are both located on one side of the auger shaft 10 in the advancing direction, and the two pickup shafts 11 and the auger shaft 10 are both horizontally arranged in parallel along the first direction a. The advantage of this arrangement is that the probability of successful picking up of straw during picking up can be increased as much as possible, and of course in practice 3 or more shafts 11 can be provided in a similar manner to further enhance the probability of straw being picked up.

After the two pickup shafts are provided, as shown in fig. 3 and 4, the projecting height of the pickup claw 110 on the pickup shaft 11 far from the auger shaft 10 can be set larger than the projecting height of the pickup claw 110 on the pickup shaft 11 near the auger shaft 10. Thus, when the land is soft, such as muddy or snowy conditions, even if straw parts sink into the ground or snow surface, the straws can be firstly turned up by the higher picking hammer claw 110, then picked up by the picking hammer claw 110 on the second picking shaft 11 and transferred to the auger shaft 10 at the rear, the higher picking hammer claw 110 on the first picking shaft 11 is mainly used for picking out the straws from the soil, and the lower picking hammer claw 110 on the second picking shaft 11 is mainly used for reducing the probability of picking up sandstone and soil.

In the following, another embodiment of the present application will be described with reference to fig. 5, wherein a plurality of crushing cutter heads 100 are convexly disposed on the outer peripheral wall of the end of the auger shaft 10 close to the first fan 4, in the embodiment shown in fig. 5, two picking shafts 11 are disposed in the picking and walking module 1, which may also be disposed as 1, or 3, and the embodiment shown in fig. 5 is only for illustrating the implementation manner of the auger shaft 10, and no particular limitation is imposed on other modules.

In the embodiment shown in fig. 5, a plurality of crushing cutter heads 100 are protruded from the outer peripheral wall of the auger shaft 10 near the end of the first fan 4. Those skilled in the art should be familiar with the specific implementation of providing a corresponding housing or drum capable of accommodating chopped straw at the end where the crushing cutter head 100 is provided, and will not be described in detail herein. The auger shaft 10 that sets up like this can once smash the straw earlier, is convenient for carry the dust removal processing behind the dust removal rotary cage 3, cooperates the crushing section 201 on the longer crushing arbor 20 that can set up again, can make the straw obtain sufficient crushing, greatly reduced the straw can be by the kibbling lower limit to satisfy more diversified straw preparation demand.

In the embodiment shown in fig. 1 to 5, a second fan 5 is further included, and the opening of the second fan 5 faces the end of the smashing section 201 away from the auger section 200, so that the straw smashed by the smashing section 201 can be conveyed to a compressor, a storage bin and other parts, and can be properly utilized. In order to further enhance the dust removal effect, as a preferred implementation manner, the outlet of the second fan 5 is connected with a feeding pipe 50, and a dust removal screen 51 is arranged on the pipe wall of the feeding pipe 50, so that dust removal can be performed again before the straw is blown out. At the same time. The housing of the first fan 4 is provided with a dust removal opening 40, and after the dust removal opening is arranged, the straw can be subjected to three times of dust removal through the first fan, the dust removal rotating cage and the second fan, so that the dust content in the obtained straw segments can reach a lower numerical value finally.

As a preferred implementation manner, the crushing cutter shafts 20 are arranged in parallel along the horizontal direction, and the length of the crushing cutter shafts 20 is not less than half of the length of the pickup shaft 11. As shown in figure 3, because the straw picking and smashing assembly provided by the embodiment of the application adopts the mode of stacking and arranging the picking and walking module 1 and the smashing module 2, the picking shaft 11 is provided, the packing auger shaft 10 and the smashing cutter shaft 20 are arranged in a larger space, therefore, under the preferable condition, the picking shaft 11 and the packing auger shaft 10 are equal in length, the length of the smashing cutter shaft 20 is not less than half of the picking shaft 11, the picking efficiency can be ensured, the lower limit of the size of the smashed straw is reduced as much as possible, and the straw cutting sections with different sizes can be efficiently produced as required.

In the embodiment shown in fig. 1, 2 or 3, the inlet 31 of the dedusting rotary cage 3 is arranged at the top of the cage body 30, and the outlet of the first fan 4 is arranged opposite to the inlet 31. The dedusting rotary cage 3 is a common device in the field, and the dust in the straw can be thrown out as much as possible under the rotating centrifugal action of the cage body 30 of the dedusting rotary cage 3 by matching with structures such as a screen, a filter screen, gauze and the like after the straw is thrown from the upper part, so that the dust content in the finally obtained straw product is reduced. After the dust removal effect of the dust removal rotating cage 3, if the satisfactory dust removal amount can be achieved, the feed can be directly converted into the livestock feed for utilization.

The embodiment of the application also provides a straw picking and crushing machine, as shown in fig. 1, fig. 3 or fig. 5, which comprises a power input device 7 and the straw picking and crushing assembly provided by the embodiment, wherein the power input device 7 is at least connected with a picking shaft 11, an auger shaft 10, a crushing cutter shaft 20, a first fan 4 and a second fan 5 and transmits power. The power input device 7 can be a combination of a connecting rod and a gearbox which are connected with a tractor for dragging the whole straw picking and smashing assembly and used for transmitting the power of a tractor engine to the mechanism, or can be an independent gasoline engine or an independent fuel engine, and the skilled person can know how to realize the power input device 7 to meet the condition that the whole straw picking and smashing assembly can normally work.

The above description is only a preferred embodiment of the application and is illustrative of the principles of the technology employed. It will be appreciated by those skilled in the art that the scope of the invention herein disclosed is not limited to the particular combination of features described above, but also encompasses other arrangements formed by any combination of the above features or their equivalents without departing from the inventive concept.
