Problems solved by technology

The vibrating feeder can screen out some small-sized materials and soil inclusions during the conveying process, but the general arrangement angle is within the range of -10°~0°, and the materials cannot be conveyed obliquely. The feeding is unstable and prone to flushing Problem causes crusher overload to shut down
In addition, during the production process, it is very easy to cause the vibrating feeder to be crushed to death by the material in the upper hopper due to improper production management, and the vibrating feeder can only be restarted after emptying the material.
The apron feeder can convey materials obliquely upwards, the feeding is stable, and it can be started with load, but the equipment cost is high, and some small-grained materials and soil inclusions cannot be screened out during the conveying process, and the subsequent desilting process for aggregate production and Serious effect on aggregate quality
[0003] For example, Chinese utility model patent CN201920238167.X: Connecting rod vibrating feeder, which relates to a connecting rod vibrating feeder, which mainly optimizes the layout of the symmetrical plane of the counterweight and the eccentric bearing, so that it has fast feeding. advantages, but it does not have the screening function and cannot guarantee the quality of subsequent raw materials

Embodiment 1

[0024] A connecting rod type low-resistance feeder, comprising a frame 9, a support 7 and a motor 1; side plates 8 are provided on both sides of the frame 9; The first bar 10 and the second bar 13; the support 7 is located below the frame 9; the first bar 10 and the support 7 are hinged for supporting the first bar 10 and driving the first bar 10 A rod 10 moves a swing rod 6; the motor 1 is connected with a crank shaft 3; a connecting rod 4 is hinged between the crank shaft 3 and the swing rod 6; the motor 1 drives the crank shaft 3 to rotate to drive the swing rod 6 movement, so that the first bar 10 and the second bar 13 realize periodic up-and-down circulation dislocation.

[0025] There are two swing rods 6 hinged between the first bar 10 and the support 7, and the joints between the first bar 10, the support 7 and the two swing rods 6 form a parallelogram structure. The main advantage of adopting the parallelogram structure is that the two pendulums are always parallel, ...

Embodiment 2

[0038] The specific difference between embodiment 2 and embodiment 1 is that there is a gap between the first rod 10 and the second rod 13 . By adopting this design, the primary screening of materials can be realized, so that during the transportation of materials, materials smaller than the distance between the first bar 10 and the second bar 13 will fall from the gap, and small pieces of materials and soil can be screened It is beneficial to the crushing and screening treatment of the subsequent process and improves the quality of the final product.

[0039]At the same time, during operation, the first bar 10 periodically pushes the material forward and upward, and periodically moves backward and downward from the material, which reduces the resistance of the system operation and greatly reduces the energy consumption of the equipment operation. Realize the stable feeding of the feeder, and there will be no problems of being crushed or punched by the material. figure 1 It i...

Embodiment 3

[0042] The concrete difference of embodiment 3 and embodiment 2 and embodiment 1 is:

[0043] The first rod 10 in embodiment 3 is a periodic movable structure (refer to embodiment 1 and embodiment 2 for details), and the second rod 13 is also a periodic movable structure (that is, the structural design of the second rod 13 is the same as that of the first rod 13). A stick 10 is consistent, so no more details). It should be noted that: when the first bar 10 and the second bar 13 are in operation, they are misaligned structures and cannot be synchronized. Therefore, after adopting the above-mentioned structural design, the screening efficiency can be further improved, the frequency of dislocation screening between the two can be accelerated, and the material conveying efficiency can be improved.

Abstract

The invention relates to the field of feeders, and particularly discloses a connecting rod type low-resistance feeder which comprises a rack, a support and a motor. Side plates are arranged on the two sides of the rack. Multiple first bars and second bars which are distributed in a staggered manner are arranged in the rack. The support is located below the rack. Swing rods are hinged between the first bars and the same side of the support. The motor is connected with a crankshaft. Connecting rods are hinged between the crankshaft and the swing rods. Compared with the prior art, the connecting rod type low-resistance feeder has the beneficial effects that the connecting rod type low-resistance feeder can be used in various ore conveying projects and has the advantages of being low in resistance, capable of saving energy, capable of conveying materials within the angle range of -10-+23 degrees and capable of screening out materials smaller than a certain particle size.

Description

technical field [0001] The invention relates to the field of feeders, in particular to a connecting rod type low-resistance feeder. Background technique [0002] The current ore crushing process generally uses a vibrating feeder or an apron feeder to transport the material to the crusher. The vibrating feeder can screen out some small-sized materials and soil inclusions during the conveying process, but the general arrangement angle is within the range of -10°~0°, and the materials cannot be conveyed obliquely. The feeding is unstable and prone to flushing The problem caused the crusher to overload and shut down. In addition, due to improper production management during the production process, the vibrating feeder is easily crushed to death by the material in the upper hopper, and the vibrating feeder can only be restarted after emptying the material. The apron feeder can convey materials obliquely upwards, the feeding is stable, and it can be started with load, but the eq...
