The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example 1:

a connecting rod type low-resistance feeder comprises a frame 9, a support 7 and a motor 1; side plates 8 are arranged on two sides of the frame 9; a plurality of first bars 10 and second bars 13 which are distributed in a staggered manner are arranged in the frame 9; the support 7 is positioned below the frame 9; a swing rod 6 for supporting the first bar 10 and driving the first bar 10 to move is hinged between the first bar 10 and the support 7; the motor 1 is connected with a crank shaft 3; a connecting rod 4 is hinged between the crank shaft 3 and the oscillating bar 6; the motor 1 drives the crank shaft 3 to rotate to drive the swing rod 6 to move, so that the first bars 10 and the second bars 13 realize periodic up-and-down cyclic dislocation.

Two swing rods 6 hinged between the first bar 10 and the support 7 are arranged, and a parallelogram structure is formed among hinged points connected with the first bar 10, the support 7 and the two swing rods 6. The parallelogram structure has the main advantages that the parallelism between the two swing rods is kept all the time, the angular displacement, the angular velocity and the angular acceleration of the two swing rods are also equal all the time, and the stability and the reliability of the integral operation of the equipment are improved. In the specific implementation process, the number of the corresponding swing rods 6 can be increased according to the situation, but the swing rods 6 are required to be ensured to be parallel to each other and form a parallelogram structure with the first bar 10 and the support 7. And the connection of the hinge points is hinged by a pin shaft 5.

A plurality of grooves are formed on the crank shaft 3; a connecting rod 4 is hinged between each groove and the corresponding first bar 10, and the connecting rod 4 is parallel to the first bar 10.

The number and position of all the grooves are the same, so that all the oscillating bars 6 oscillate synchronously at the same angle.

The top surfaces of the first bars 10 and the second bars 13 are smooth surfaces, patterned surfaces or corrugated surfaces.

The top surfaces of the first bar 10 and the second bar 13 may be provided with a weld overlay or a wear resistant coating.

The included angle between the frame 9 and the horizontal plane is-10 degrees to +23 degrees.

The hinge point of the connecting rod 4 and the swing rod 6 is coincided with the hinge point of the swing rod 6 and the first bar 10. The design of the hinge point here is preferably optimized to provide a more efficient power transmission, but of course it is equally possible to ensure that the hinge point of the connecting rod 4 and the rocker 6 is located on the rocker 6.

The motor 1 is provided with a speed reducer 2, and the motor is an asynchronous motor, a reluctance motor or a permanent magnet motor.

The working principle is as follows:

the motor 1 drives the crank shaft 3 to rotate and drives the swing rod 6 to swing through the connecting rod 4; so that the first bar 10 makes a periodic movement.

The periodic swing of the first bar 10, initially, the top surface of the first bar 10 is lower than the top surface of the second bar 13 (as shown in fig. 3), and with the forward swing of the swing link 6, the top surface of the first bar 10 is driven to lift, when the top surface of the first bar 10 is coplanar with the second bar 13 (as shown in fig. 4), the top surface of the first bar 10 contacts with the material, the swing link 6 continues to swing forward, and the top surface of the first bar 10 is higher than the top surface of the second bar 13 (as shown in fig. 5), so that the first bar 10 pushes the material upward and forward. After the swing rod 6 swings forwards to the maximum angle, the swing rod swings backwards to drive the first bar 10 to swing backwards and downwards, the top surface of the first bar 10 gradually lowers, when the swing rod is lowered to be in the same plane as the top surface of the second bar 13, the material is not supported, then the swing rod 6 continues to swing backwards until the maximum angle, the top surface of the first bar 10 is lower than the top surface of the second bar 13, and the material is supported by the second bar 13. The periodic oscillation of the first bars 10 causes the material to move periodically forward and vibrate up and down with small amplitude.

Through the steps, the material conveying is realized, the upward material conveying at a certain angle can be met, and the problem that the upward material conveying cannot be carried out by a vibrating feeder or a plate-type feeding machine is solved. In the process of conveying materials upwards, smaller materials can fall to the bottom along with the materials, and cannot be conveyed upwards, so that the crushing and screening treatment of subsequent processes is facilitated, and the quality of final products is improved.

Example 2:

example 2 differs from example 1 specifically in that: a gap is present between the first bar 10 and the second bar 13. Through adopting this design, can realize the elementary screening of material for the material can fall from the clearance in transportation process, and the material that is less than interval between first stick 10 and the second stick 13 can be sieved the fritter material with pressing from both sides native, is favorable to subsequent handling's breakage and screening to be handled, improves final product quality.

Meanwhile, in the operation process, the first bars 10 periodically push the materials forwards and upwards and periodically separate from the materials backwards and downwards, so that the resistance of the system in operation is reduced, and the energy consumption of the equipment in operation is greatly reduced. Realize the steady feed of batcher, can not appear by the problem that the material died or washed the material. Fig. 1 is a schematic diagram of the horizontal arrangement, and an included angle between the rack 9 and the horizontal plane can be arbitrarily adjusted within a range of-10 degrees to +23 degrees, so that the method can adapt to more process conditions.

In the above-described embodiments 1 and 2, the first bars 10 are of the periodically movable structure, and the second bars 13 are of the fixed structure. The periodic up-down cyclic dislocation is realized by the movement of the first bar 10 and the fixation of the second bar 13.

Example 3:

example 3 differs specifically from examples 2 and 1 in that:

the first bar 10 in embodiment 3 is of a periodic movable structure (refer to embodiments 1 and 2 specifically), and the second bar 13 is also of a periodic movable structure (i.e. the structural design of the second bar 13 is consistent with that of the first bar 10, and therefore, the description thereof is omitted). It should be noted that: when the first bar 10 and the second bar 13 are operated, the bars are in a staggered structure and cannot be synchronized. Therefore, after the structural design is adopted, the screening efficiency can be further improved, the staggered screening frequency of the screening efficiency and the screening efficiency is accelerated, and the material conveying efficiency is improved.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
