Each 8 pin joints of lever all be fixed with a torsional spring, the other end of torsional spring is fixed on through-hole 14, the torsional spring makes lever 8 be in horizontal position all the time under the condition of not receiving external force.

The lower end of each vertical rod 12 is fixed with a rectangular plate 13 which is horizontally arranged.

Before the device is used, a belt for transporting materials is fixed in the middle position above a shell 1, a flat plate 9 is positioned in the middle of the front position and the rear position of the belt, a blanking position is positioned on the right side of a fixed plate 2, the device is integrally arranged above a feed inlet of a jaw crusher, a jaw plate is aligned to the right side of the fixed plate 2, and baffles 5 on the left side of a rotating shaft 3 are all in horizontal positions and are in contact with the upper end face of a protruding part on the right side of a lever 8;

when the invention is used, after materials are conveyed to the upper part of the shell 1 by a belt and unloaded, the materials continuously fall on the baffle plates 5 at the front side and the rear side from the front side and the rear side of the flat plate 9 respectively, the materials accumulated above the two baffle plates 5 are gradually increased, the gravity is increased therewith, the two baffle plates 5 downwards press the lever 8, the lever 8 overcomes the torsion force of the torsion spring to rotate clockwise along a hinge point, the left end of the lever 8 upwards jacks up the vertical rod 12 through the rectangular plate 13, the vertical rod 12 drives the horizontal rod 10 at the left end to move upwards through the horizontal plate 11, the slide block 16 upwards slides along the slide groove 17, because the blanking amount at the front side and the rear side can not be completely consistent, the situation that the baffle plate 5 at one end is heavy in material receiving and the baffle plate 5 at the other end is light in material receiving amount can be generated, the two baffle plates 5 can generate relative displacement under the condition that the material receiving amount is different, because the front baffle plate 5 and the rear baffle plate 5 are matched through the groove 6 and the baffle 7, the relative displacement amount of the two baffle plates 5 is controlled by the interval, the two baffles 5 can generate relative displacement and are not separated from each other, the amplitude of downward swing of one side baffle 5 receiving the material weight is larger, the pressure applied to the lever 8 is larger, the clockwise rotation angle of the side lever 8 is larger, the rising height of the vertical rod 12 is higher, the transverse plate 11 is inclined and drives the left end transverse rod 10 to rotate, the left end transverse rod 10 drives the right end transverse rod 10 to rotate in the opposite direction through the gear 19, the upper end of the flat plate 9 swings towards one end receiving the material weight, so that the feed opening on one side receiving the material weight is reduced and the feed opening on one side receiving the material light is enlarged, the subsequent falling material enters the side receiving the material light more until the material receiving amount of the two baffles 5 is the same, the height difference of the two vertical rods 12 is reduced to zero, the flat plate 9 returns to the vertical state again, if the subsequent material receiving is carried out, the gravity of the side baffle 5 originally receiving the material weight exceeds the side baffle 5 originally receiving the material weight, and the flat plate 9 continues the swing process, realize the dynamic balance of both sides baffle 5 material volume of receiving, when one side baffle 5 material volume of receiving reaches and to extrude lever 8 to the weight of maximum rotation angle, and when another end baffle 5 did not reach this weight, because the interval cooperation through recess 6 and dog 7 between two front and back baffles 5, make two baffles 5 can not rotate downwards when arbitrary one side has reached the weight that can extrude lever 8 to maximum rotation angle yet, but wait for another side baffle 5 also to reach synchronous upset downwards behind this weight, baffle 5 can be with the material of connecing downwards throw in to between two jaw plates of jaw crusher after the upset downwards, lever 8 resets to horizontal position under the effect of torsional spring, baffle 5 drives drum 4 and rotates 90 and makes next baffle 5 rotatory to the level and is blockked by lever 8 right-hand member, the next round of receiving is restarted.

According to the invention, the two levers 8 block the two baffles 5 from rotating under the action of the torsion spring, so that the front and rear side baffles 5 can receive falling materials of the belt, and the baffles 5 can rotate downwards to discharge materials until the gravity of the received materials can overcome the torsion of the torsion spring, thereby realizing the purpose of quantitative discharging; the two levers 8 are different in gravity for containing materials through the front side baffle 5 and the rear side baffle 5, so that the supporting heights of the left end to the two vertical rods 12 are different, the transverse plate 11 is inclined, the flat plate 9 is driven to rotate through the transverse rod 10, the sizes of the material receiving openings on the front side and the rear side of the shell 1 are changed through the rotation of the flat plate 9, more subsequent falling materials fall onto the side baffle 5 with light material receiving amount, the dynamic balance of the material receiving amount in the front and rear direction is achieved, the quantitative blanking of the jaw crusher is realized, the materials falling between the jaw plates are relatively uniform in the front and rear direction, the crushing efficiency of the jaw crusher is greatly improved, the occurrence of material returning is prevented, and the service life of the jaw plates is prolonged;

according to the invention, the front baffle 5 and the rear baffle 5 of the baffle 5 are matched with each other at intervals through the groove 6 and the stop dog 7, so that the two baffles 5 can rotate relatively to change the sizes of the corresponding upper end openings while not being separated from each other, a material is placed between the two baffles 5 to cause a metering error, meanwhile, the two baffles 5 cannot rotate downwards when any one side reaches the weight capable of extruding the lever 8 to the maximum rotation angle, but synchronously turn downwards after the other side baffle 5 also reaches the weight, and the synchronous unloading of the two baffles 5 is ensured.
