Abstract
The utility model relates to a thresher with an anti-blocking function, which comprises a frame, a threshing box and a power mechanism. A threshing cylinder is arranged in the threshing box, and a recess plate sieve is arranged on the lower side of the threshing cylinder. The thresher is characterized in that the recess plate sieve consists of a front recess plate and a rear recess plate which are hinged with each other, the front recess plate is fixed to the frame, and the rear recess plate is connected with the frame by the aid of an elastic mechanism. The thresher with the anti-blocking function is simple in structure, not easy to block and less in impact on threshing performance.
Description
Technical field
The utility model relates to a kind of thresher, especially relates to a kind of thresher with anti-clogging function.
Background technology
The separating mechanism of thresher is made of threshing cylinder and threshing concave plate, and the gap between threshing cylinder and the notch board directly affects the threshing performance, and cylinder-concave clearance can be adjusted within the specific limits.Gap between present most of type threshing cylinder and notch board is fixing nonadjustable.Indivedual types have the adjustment function, are immutable but adjust course of work intermediate gap, back.Threshing chamber will result in blockage when occurring in operation process that moment, feed quantity surpassed design load, and machine can not carry out operation.Publication number is that the Chinese patent of CN 2598327 discloses a kind of harvester threshing chamber preventing clogging up device; it is in activity; one side of plate mark of mouth plate; cardan axle is installed; pass through cardan axle; movable; plate mark of mouth plate twists with the threshing casing and is connected; in activity; the below of plate mark of mouth plate; the strand connection and is had the elastic support that compresses spring; elastic support activity by resilient support; plate mark of mouth plate; the straw material that enters according to threshing chamber what; movable; plate mark of mouth plate can regulate automatically and threshing cylinder between distance, can highly effectively prevent the obstruction of straw material.This plate mark of mouth plate is equivalent to concave grate, and when occurring blocking up look, its whole concave grate all rotates, and this is just greater than having reduced its threshing performance.
Summary of the invention
The utility model mainly is that the threshing case that solves the existing in prior technology thresher stops up easily, and the technical problem of cleaning trouble provides a kind of simple in structure, difficult obstruction, and the thresher with anti-clogging function little to the threshing performance impact.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of thresher with anti-clogging function; comprise frame, threshing case, actuating unit; be provided with threshing cylinder in the threshing case; the downside of threshing cylinder is provided with concave grate; it is characterized in that described concave grate is made of preceding notch board and back notch board; forward and backward notch board is hinged, and preceding notch board and frame fix, and back notch board links to each other with frame by elastic mechanism.In threshing course, when take place stopping up between concave grate and the threshing cylinder, the pulling force that back notch board overcomes elastic mechanism rotates, and makes the pitch enlargement between the notch board and threshing cylinder afterwards, gets lodged in wherein forage and is taken off feed roller rapidly and take away.Because cylinder-concave clearance can adjust in the reasonable scope automatically, therefore avoided strengthening the clogging that forms because of feed quantity moment, improved operating efficiency, reduced the fault rate of machine simultaneously.Because cylinder-concave clearance can be adjusted in reasonable range automatically, machine is more wide to the accommodation of crop yield and operating speed, has improved the adaptability of machine again.Simultaneously, because afterwards notch board is when rotating, preceding notch board does not rotate, and is therefore, very little to the influence of taking off the material effect.
As preferably, described elastic mechanism comprises a sleeve that links to each other with frame, is provided with flexible member in the sleeve, back notch board is provided with a screw rod, this screw rod penetrates from the downside of flexible member, and screw rod upside end is in the upside of flexible member, and fixes by pressing plate and nut and flexible member.When the back notch board rotated, the recurve strip was moved screw motion, and screw rod overcomes the flexible member motion, and when blockage problem was eliminated, back notch board returned to original state under the effect of flexible member.
As preferably, described flexible member is a compression spring.
As preferably, described before the length ratio of notch board and recurve be 2 ︰, 3 to 1 ︰ 1.Back notch board is too big, then its when rotating to take off the material effect to influence meeting very big, then notch board is too small, and is when then it rotates, very little to eliminating the effect of stopping up.
As preferably, described flexible member is in its pre-compressed state when the thresher operate as normal.When feed quantity instantaneous when excessive, extruding force is greater than pretightning force between cylinder and notch board, flexible member crimp, back notch board rotates around the shaft, cylinder-concave clearance strengthens, and extruding force reduces, and cereal passes through smoothly in the threshing chamber, because the extruding force that the thrust of flexible member produces greater than threshing, screw rod pulling back notch board rotates the answer normal condition around the shaft afterwards.
The beneficial effect that brings of the present utility model is; the threshing case that has solved the existing in prior technology thresher stops up easily; and the technical problem of cleaning trouble has realized a kind of simple in structure, difficult obstruction, and the thresher with anti-clogging function little to the threshing performance impact.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: as shown in Figure 1; the utility model is a kind of thresher with anti-clogging function; comprise frame 1, threshing case, actuating unit; be provided with threshing cylinder 2 in the threshing case, the downside of threshing cylinder 2 is provided with concave grate, and described concave grate is made of preceding notch board 3 and back notch board 4; the length of forward and backward notch board is than being that 1 this length of ︰ 1(is meant that it is in the length of taking off on the feed roller rotation direction); and be hinged, preceding notch board 3 fixes with frame 1, and back notch board 4 links to each other with frame 1 by elastic mechanism.Elastic mechanism comprises a sleeve that links to each other with frame 5, be provided with compression spring 6 in the sleeve, back notch board is provided with a screw rod 7, and this screw rod 7 penetrates from the downside of compression spring 6, screw rod 7 upside ends are in the upside of compression spring, and fix by pressing plate and nut and compression spring.
The utility model is in threshing course, and when take place stopping up between concave grate and the threshing cylinder, the pulling force that back notch board overcomes elastic mechanism rotates, and makes the pitch enlargement between the notch board and threshing cylinder afterwards, gets lodged in wherein forage and is taken off feed roller rapidly and take away.Because cylinder-concave clearance can adjust in the reasonable scope automatically, therefore avoided strengthening the clogging that forms because of feed quantity moment, improved operating efficiency, reduced the fault rate of machine simultaneously.Because cylinder-concave clearance can be adjusted in reasonable range automatically, machine is more wide to the accommodation of crop yield and operating speed, has improved the adaptability of machine again.Simultaneously, because afterwards notch board is when rotating, preceding notch board does not rotate, and is therefore, very little to the influence of taking off the material effect.
So the utlity model has simple in structure, the difficult obstruction, and to features such as the threshing performance impact are little.
