Abstract
The utility model relates to a hoisting push-down vibrating screen of a self-propelled harvester and relates to the technical field of harvesters. The hoisting push-down vibrating screen solves the problems that screen boxes are large in pushing resistance, the screen boxes and related parts are easy to damage, maintenance frequency is high, operation efficiency is affected, technology is difficult and the like are effectively solved. The vibrating screen comprises a screen box and a crankshaft and connecting rod mechanism. One or two hosting front rocker rods are arranged on the upper portion of the screen box, two rear rocker rods are arranged on the lower portion of the screen box, the upper ends of the two rocker rods are hinged with a support shaft, the lower ends of the two rear rocker rods are fixed on a rotating shaft connected with a framework rotationally, two ends of the support shaft are respectively fixed to two ends of the lower portion of the screen box, and a middle connecting rod of the crankshaft and connecting rod mechanism is hinged with the middle of the support shaft. The hoisting push-down vibrating screen has the advantages that the vibrating screen is simple in processing technology, vibration resistance of the screen box is reduced, production efficiency is greatly improved, and the problem that damages of the screen box and the related mating parts is solved.
Description
Technical field
The utility model relates to the cropper technical field.
Background technology
The vibratory sieve of present existing self propelled harvester adopts the power-assisted side, modes such as suspension rod underlying.The mode of vibration resistance is big or to sieve manufacture craft requirement condition height, is difficult to proof strength, and very easily causes sieve to damage or the auxiliary equipment of being correlated with damages, and causing the tractor driver to gather in cost increases.
A kind of vibratory sieve transmission mechanism is arranged in the prior art, constructing of rocking bar itself transformed, be arranged to 7 font rocking bars, and rocking bar does not adopt lift-on/lift-off type, has no idea to avoid the generation of the problems referred to above equally, also has a kind of harvester vibratory sieve stroke control mechanism, also relate to rocking bar, but its structure than big difference, so that above-mentioned two kinds of prior aries all can not solve the mode of vibration resistance is bigger, easily causes vibratory sieve or relevant auxiliary equipment to damage high this drawback of damage frequency with this novel existence.
Now be badly in need of a kind ofly overcoming existing self propelled harvester vibratory sieve damage frequency height, the shortcoming of complex process can improve the vibratory sieve that operating efficiency and tractor driver gather in the crops efficient.
The utility model content
Technical problem to be solved in the utility model provides that a kind of screen box is not fragile, durable with relevant auxiliary equipment, the lifting down-push type vibratory sieve of the self propelled harvester that can enhance productivity.
For solving the problems of the technologies described above, technical solution adopted in the utility model provides a kind of self propelled harvester lifting down-push type vibratory sieve: comprise screen box, toggle, the top that it is characterized in that screen box is provided with the preceding rocking bar of one or two lift-on/lift-off type, rocking bar after the bottom of screen box is provided with 2, the upper end of rocking bar all is twisted together with the holder axle after 2, the lower end of rocking bar is fixed in the rotating shaft after 2, and rotating shaft and frame are rotationally connected; The two ends of described holder axle are individually fixed in the two ends of screen box bottom, and the middle part of the middle connecting rod of toggle and holder axle is twisted together.
Preferably: rocking bar is twisted together by rubber shaft bearing and screen box before described.The upper end of rocking bar all is twisted together by bearing and holder axle after described 2, and is provided with gland.
This novel screen box adopts whole pressing and bending moulding.This device needs earlier auxiliary equipments such as screen box subiculum axle, rubber shaft bearing, front and back rocking bar to be assembled, and the part that will assemble and peeling machine underframe spool are assembled by rocking bar before the fixing sieve and holder then, are connected with the middle connecting rod of toggle again.Screen box, preceding rocking bar, back rocking bar, rubber shaft bearing, middle connecting rod, holder axle are connected and fixed, thus the input eccentric shaft of toggle rotate drive in connecting rod promote to rock the holder axle, preceding rocking bar, back rocking bar rotate to reach the purpose of screening.
The beneficial effect that adopts technique scheme to produce is: because this mechanism has changed power-assisted point and adopted preceding rocking bar lift-on/lift-off type, solve its structural strength problem, its processing technology is comparatively simple, enhances productivity greatly, has solved problems such as screen box and relevant auxiliary equipment be fragile.
Description of drawings
The structural representation of an embodiment of Fig. 1 the utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Among the figure: 1, screen box 2, preceding rocking bar 3, back rocking bar 4, middle connecting rod 5, input eccentric shaft 6, holder axle 7, rotating shaft 8, gland 9, rubber shaft bearing 10, eccentrically weighted shaft.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Shown in Fig. 1-2, the structure of this self propelled harvester lifting down-push type vibratory sieve comprises screen box 1, toggle, the top that it is characterized in that screen box 1 is provided with the preceding rocking bar 2 of one or two lift-on/lift-off type, rocking bar 3 after the bottom of screen box 1 was provided with 2, the upper end of rocking bar 3 all is twisted together with holder axle 6 after 2, the lower end of rocking bar 3 is fixed in the rotating shaft 7 after 2, and rotating shaft 7 is rotationally connected with frame; The two ends of described holder axle 6 are individually fixed in the two ends of screen box 1 bottom, and the middle part of the middle connecting rod 4 of toggle and holder axle 6 is twisted together.Rocking bar 2 is twisted together by rubber shaft bearing 9 and screen box 1 before described.The upper end of rocking bar 3 all is twisted together by bearing and holder axle 6 after described 2, and is provided with gland 8.
Described screen box 1 adopts whole pressing and bending moulding.This device needs earlier auxiliary equipments such as screen box 1 subiculum axle 6, rubber shaft bearing 9, preceding rocking bar 2, back rocking bar 3 to be assembled, and the part that will assemble and peeling machine underframe are assembled by rocking bar 2 before the fixing sieve and holder axle 6 then, and middle connecting rod 4 connects again.Screen box 1, preceding rocking bar 2, back rocking bar 3, rubber shaft bearing 9, middle connecting rod 4, holder axle 6 is connected and fixed, under the drive by external motor, thereby input eccentric shaft 5 begins rotation to be rocked back and forth by connecting rod 4 in eccentrically weighted shaft 10 drives, and promote holder axle 6 by middle connecting rod 4 and rock, because rocking bar 3 tops, back and holder axle 6, the active link that rotating shaft 7 and the frame of bottom all adopts, so not only played supporting role but also can swing back and forth along with rocking of holder axle 6, thereby form an integral body, played the effect of rocking back and forth to screen box 1, rocking bar 2 also is being twisted together of adopting with screen box 1 and machine upper frame before the top lift-on/lift-off type of screen box 1 simultaneously, before rocking bar also swing along with rocking of screen box 1, thereby played the purpose of screening.
The beneficial effect that adopts technique scheme to produce is: because this mechanism has changed power-assisted point and adopted preceding rocking bar lift-on/lift-off type, during vibration the reduction of income screen box resistance, its processing technology is comparatively simple, enhances productivity greatly, has solved problems such as screen box and relevant auxiliary equipment be fragile.
