Description
Technical field
The present invention relates to a kind of thresher, especially relate to a kind of threshing box of thresher.
Background technology
Thresher is the visual plant in the processing of a kind of grain harvest; now to obtain general application, existing thresher generally comprises a threshing box, is provided with sorting screen on the downside of threshing box; be provided with cereal transmission system on the downside of sorting screen, in threshing box, be provided with threshing cylinder and concave grate.But, due to the difference of grain species, the difference of the dry wet degree of cereal, and the difference of stalk intensity, there are not same needs, in existing situation to concave grate and threshing cylinder, generally can only the rotating speed speed of threshing cylinder regulate, and be difficult to realize to the adjustment of concave grate, in some extreme environments, the adjustment of people to concave grate is only limitted to carrying out adaptive replacing.Therefore, concave grate of the prior art can't carry out adjusting in time according to operating environment and crop situation.
Summary of the invention
The present invention mainly solves the notch board of the thresher existing for prior art can not according to the technical problem adjusted timely by industry environment and crop situation; there is provided a kind of structure simple, easy to operate, by the adjustable threshing box adjusted timely and effectively the spacing between concave grate and threshing box.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of adjustable threshing box, comprise casing, concave grate is provided with in casing, threshing cylinder, it is characterized in that the left side of described concave grate is connected with described body pivot, right side is provided with up-down adjustment mechanism, described up-down adjustment mechanism comprises a U-shaped regulating block be connected with described concave grate, the both sides, front and back of this U-shaped regulating block are provided with mutually corresponding chute, the centre of U-shaped regulating block is provided with a longitudinal screw block, this longitudinal screw block is connected and described U-shaped regulating block by former and later two adaptive slide bars corresponding to described chute, longitudinal screw block is provided with an adjusting screw(rod) adaptive with it, one end of this adjusting screw(rod) is rotationally connected by the supporting mechanism being fixed on casing accordingly, described adjusting screw(rod) is connected with a driving mechanism by transmission mechanism.Cereal is being carried out in the process of threshing, the situation of cereal is different to concave grate from the requirement of the optimal spacing of threshing cylinder, the humidity of such as cereal is excessive, just need the spacing of concave grate and threshing cylinder a little large, stucking phenomena is there will not be to make it, so the present invention in use, can regulate concave grate according to the change of various state, when needed, adjusting screw(rod) is rotated by driving mechanism, it is rotated relative to supporting mechanism, at rotation process, longitudinal screw block can move up or down, also moving slide-bar moves in the chute of U-shaped regulating block, in the moving process of slide bar, U-shaped regulating block and coupled concave grate is driven to deflect up or down, thus reach the adjustment of the spacing to concave grate and threshing cylinder.
As preferably, described driving mechanism is a stepper motor, described casing is provided with the gravity sensor that is surveyed its weight, the rotating shaft of threshing cylinder is provided with torque sensor, this gravity sensor and torque sensor are all connected with a control unit, control unit is connected with described stepper motor, the weight amount obtained when gravity sensor exceedes capping, and the torque value that torque sensor obtains is when exceeding capping, driving stepper motor adjusting screw(rod) rotates, and concave grate is deflected down; When weight amount is lower than setting lower limit, and torque value is lower in limited time lower than setting, and driving stepper motor adjusting screw(rod) rotates, and concave grate is upward deflected; When weight amount and torque value have at least one to be between its bound, stepper motor does not work, and keeps the position of concave grate.When normal operation, the weight of the crop of casing and its inside is in a normal operation interval, prescribe a time limit when its weight exceedes the upper of its operation interval, likely there is blocking, likely that the kind of crop changes, also be likely the reasons such as the humidity of crop is excessive, if the change of this weight does not cause the larger change of the moment of torsion of the rotating shaft of threshing cylinder (in the technical program, torque value does not reach the upper limit of its setting numerical value), then do not need to adjust concave grate, if there is larger change in torque value, namely torque value reaches the maximum of its setting numerical value, then start stepper motor, the spacing of adjustment concave grate and threshing cylinder, under two numerical value are all less than the lower limit of setting numerical value, just start stepper motor, the spacing of concave grate and threshing cylinder is reduced.The technical program be arranged so that automatic, instant concave grate is adjusted of threshing function, Different Crop state can be adapted to, reduce to jump a queue, the probability of card machine, reduce threshing cylinder and rotating shaft pressure, improve its job stability.
As preferably, described casing comprises box frame and corresponding shrouding, and the right side of described box frame is provided with a side seal door, and upside and the box frame of this side seal door are hinged.The right side of box frame is the side of the up-down adjustment mechanism of concave grate, as long as opening side is sealed up a door just can carry out manual adjustment operation to up-down adjustment mechanism easily, very easy to use.
As preferably, described up-down adjustment mechanism is provided with former and later two, is provided with the inner side of the rear and front end of side seal door.Concave grate is belong to one of comparatively large-scale and main stressed member in thresher; its stability is extremely important for whole separating mechanism; the technical program adjusted it by former and later two up-down adjustment mechanisms, uncomplicated in operation, and reliably highly stable in structure.
As preferably, be provided with between described side seal door and box frame offside seal up a door open after two air springs of playing a supporting role.
The beneficial effect brought of the present invention is; the notch board solving the thresher existing for prior art can not according to the technical problem adjusted timely by industry environment and crop situation; achieve a kind of structure simple, easy to operate, by the adjustable threshing box adjusted timely and effectively the spacing between concave grate and threshing box.
