Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1, the power transmission method is: the motor 3 is arranged on the upper portion of the machine body 1, the storage battery is located on one side of the motor 3 and supplies power to the motor 3, the motor 3 is connected with the scraping wheel 17 through a first belt 21 and is connected with the driving crawler wheel 4 through a second belt 22, the driving crawler wheel 4 transmits power to the driven crawler wheel 5 through the traveling crawler 6, the driven crawler wheel 5 is connected with the auxiliary picking wheel 15 through a third belt 23, an intermediate wheel 24 is rotatably connected to an inlet of the material guide cylinder 7, the intermediate wheel 24 is connected with the traction roller 10 at the inlet of the material guide cylinder 7 through a fourth belt 25, a first gear is arranged on the intermediate wheel 24, and a second gear meshed with the first gear is arranged on the auxiliary picking wheel 15. The traction roller 10 at the inlet of the material guide cylinder 7 is ensured to rotate oppositely to the auxiliary picking wheel 15, the position of the auxiliary picking wheel 15 is slightly higher than that of the traction roller 10 at the inlet of the material guide cylinder 7, and the auxiliary picking wheel 15 is used for preventing straws collected by the picking piece 9 from falling off and ensuring that the straws can enter the material guide cylinder 7. In the aspect of linear velocity, the linear velocity of the guide belt 8 is greater than that of the walking crawler belt 6 due to the existence of the intermediate wheel 24, and the traction roller 10 at the inlet of the guide cylinder 7 rotates at a high speed by matching with the smaller diameter of the traction roller 10.
As shown in fig. 1-4, in the picking unit, the adjacent picking sheets 9 at the drawing roller 10 are in an open state, the inlet of the guide cylinder 7 is convenient for collecting the straw, and the outlet of the guide cylinder 7 is convenient for releasing the straw so as to enable the straw to enter the crushing box 11; the picking-up piece 9 is in a curved plate shape, so that the straws can be 'pocketed' at the straight section of the material guide belt 8, and the comb-tooth-shaped picking-up piece 9 not only can collect the straws on the ground, but also can perform 'scraping-off' operation on rice stubbles.
The crushing unit adopts a repeated crushing mode, bevel gears 18 on two sides of a scraping wheel 17 respectively convey power to two crushing wheels 19 vertical to the scraping wheel 17, the two crushing wheels 19 are meshed inwards, the crushed straw powder falls into the bottom of a crushing box 11 and is conveyed into a space between two straight sections of a walking crawler 6 by a conveying cylinder 12, the straw which cannot be crushed can be further cut by the two crushing wheels 19 under the action of the scraping wheel 17 and then is conveyed back to the upper parts of the two crushing wheels 19, in order to ensure that the crushing wheels 19 can guide the material, the front end of each crushing wheel 19 can be slightly higher than the rear end, in addition, spiral crushing blade strips 20 used for cutting the straw can also guide the straw to the rear side, the scraping wheel 17 is of a multi-cutter head 26 structure, the cutter heads 26 are arranged at intervals, driven blades 27 matched with the cutter heads 26 are arranged on the wall surface of the crushing box 11, and the rotary cutter heads 26 and the driven blades 27 can have a secondary crushing effect on the straw by matching.
The outlet of the feeding barrel 12 is basically aligned with the moving track of the feeding positioning hole 13, so that the crushed straw can fall into the feeding positioning hole 13 as much as possible, the distribution area of the feeding positioning hole 13 on the walking crawler 6 accounts for about fifty percent, most of the straw powder can be effectively buried in the soil layer, and the straw powder which does not fall into the feeding positioning hole 13 has an opportunity to fall into the feeding positioning hole 13 again after the walking crawler 6 rotates.
The existence of the walking crawler belt 6 can enable the agricultural machine to have better passing performance after the slotting tool 14 is deeply inserted into soil, and the slotting tool 14 can bury the straws in the soil layer deeply and cannot cause larger damage to the ground, and the straws are exposed out of the soil surface again because the ground is turned over greatly.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
