Abstract
The utility model discloses a rape threshing machine. The threshing machine comprises a bracket, a rotating shaft arranged on the bracket through a bearing, a belt pulley fixedly arranged at the end of the rotating shaft, a threshing roller fixedly arranged on the rotating shaft, a concave plate arranged under the threshing roller, and a sliding plate positioned under the concave plate, wherein sieves pores are formed on the concave plate; an arc protective plate is arranged above the threshing roller; a feed port is formed at the lateral end of the arc protective plate; a fan is fixedly arranged at one side of the lower part of the bracket; and a wind guide hopper is fixedly arranged at the other side of the fan corresponding to the bracket. Rape stems mixed with rape seeds can be blown outside the threshing machine body from the wind guide hopper by utilizing wind generated by the fan, so that the workload of subsequent separation can be reduced, and the threshing efficiency can be improved.
Description
Technical field
The utility model relates to agricultural mechanical field, particularly relates to a kind of rape thresher.
Background technology
Agricultural production has at present obtained fast development, traditional rape threshing is raft after the rape harvesting, adopt the modes such as hand rubbing, pin stranding bastinade that rape seed is separated, and then with sieve, rape seed and rapeseed hull are separated, not only labour intensity is large for this rape seed disengaging method, inefficiency, and the disengaging effect is also poor.
Existing improved rape thresher is all rape seed after separation to be installed after filtration rape straw is separated with the rape seed in use; yet also include a part of rape straw in the rape seed after separating; cause separative efficiency to reduce; and increased the workload of follow-up further separation, waste time and energy.
The utility model content
The purpose of this utility model is to have the not high problem of separative efficiency for present rape thresher, provides a kind of easy to use, breaks away from the high rape thresher of efficient.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of rape thresher, comprise support, through the rack-mount rotating shaft of bearing, be fixedly mounted on roller end belt pulley, be fixedly mounted on threshing cylinder in rotating shaft, be arranged on the below of threshing cylinder notch board, be positioned at the slide plate of notch board below; Described notch board is provided with sieve aperture, is provided with the arc backplate above described threshing cylinder, and arc backplate side is provided with charging aperture, at blower fan of support bottom one side fixed installation, at wind-guiding bucket of the corresponding support opposite side fixed installation of blower fan.
The utility model passes through at blower fan of support bottom one side fixed installation; at wind-guiding bucket of the corresponding support opposite side fixed installation of blower fan, can will blow out thresher from the wind-guiding bucket with the rape straw that the rape seed mixes by the wind that blower fan produces external.Reduce the workload of later separation, guaranteed disengaging efficient.
In order more easily separated rear rape straw to be derived from discharging opening, the utility model preferably, described arc backplate inwall is provided with guide plate, is being provided with slag notch near on the arc backplate of described guide plate.
Compared with prior art, the utlity model has following advantage:
The utility model is by adopting at blower fan of support bottom one side fixed installation; and at wind-guiding bucket of the corresponding support opposite side fixed installation of blower fan; the wind that can utilize blower fan to produce will blow out thresher with the rape straw that the rape seed mixes from the wind-guiding bucket external; reduce the workload of later separation, improved disengaging efficient.
Description of drawings

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Fig. 1-2; a kind of rape thresher; comprise support 1, through the rack-mount rotating shaft 2 of bearing, be fixedly mounted on roller end belt pulley 3, be fixedly mounted on threshing cylinder 4 in rotating shaft, be arranged on the notch board 5 of the below of threshing cylinder; described notch board is provided with sieve aperture 6; just dropped out from this sieve aperture 6 by the rape seed after threshing; be provided with slide plate 7 below notch board, can be from slide plate 7 landings to support 1 lower end from the rape seed that this sieve aperture 6 drops out.Described threshing cylinder 4 tops are provided with arc backplate 8, arc backplate 8 sides are provided with charging aperture 9, arc backplate 8 inwalls are provided with guide plate 10, are being provided with slag notch 11 near on the arc backplate 8 of described guide plate 10, and the rape straw after so just breaking away from is more easily discharged from slag notch.At blower fan 12 of support bottom one side fixed installation; at wind-guiding bucket 13 of the corresponding support opposite side fixed installation of blower fan; the wind that utilizes blower fan to produce will blow out thresher with the rape straw that the rape seed mixes from the wind-guiding bucket external; make the rape seed break away from ground more complete; and reduced the workload of later separation, improved disengaging efficient.
The above; it is only the better embodiment of the utility model; but protection domain of the present utility model does not limit to therewith; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement are within all should being encompassed in protection domain of the present utility model.
