DETAILED DESCRIPTION

[0036] The present invention is described in detail below in conjunction with specific embodiments.

By reasonably controlling the discharging frequency and discharging amount and combining the mass of the counterweight block, automatic vibration without external force drive can be realized, so as to achieve the purpose of eliminating equipment power consumption, simplifying equipment structure and reducing enterprise production cost.

The specific structure is very simple and mature and has corresponding specifications, so it will not be described in detail;

[0041] The vibrating body 2 is mainly used to support the chute body and realize the absorption and buffering of kinetic energy during the vibration of the chute body under the impact of kinetic energy and the subsequent release. Its main structure includes: a mounting bracket 20, an energy storage bracket 21, and a vibration bracket 22;

[0042] The mounting bracket 20 includes two support beams 200 arranged in parallel on the left and right sides of the bottom of the chute body 1 and a connecting beam 201 located between the two support beams 200;

[0043] The support beam 200 has an L-shaped cross section, and its vertical arm is close to the chute body 1 and is provided with a plurality of first connection holes 20a; first screw holes facing the first connection holes 20a are provided on the left and right sides of the chute body 1, and the chute body 1 is connected together by connecting bolts provided in the first connection holes 20a and the first screw holes; and second connection holes are provided on its horizontal arm;

[0044] The support beam 200 is usually made of angle steel and other profiles, which has sufficient strength and is conducive to reducing costs. According to requirements, in order to ensure structural stability, a reinforcing rib plate 2000 and other structures should be configured between the two plate surfaces of the support beam;

[0045] like Figure 2 As shown, the energy storage bracket 21 is mainly used as an energy carrier, absorbs kinetic energy through its driven vibration, and releases energy through the interaction with the spring and the mounting bracket, so that the mounting bracket vibrates, and finally drives the chute to vibrate. Its main structure includes two counterweight beams 210 respectively arranged on the left and right sides of the vibrating body 2, and a plurality of pairs of third connection holes are arranged on the counterweight beam 210 along the front-to-back direction;

[0046] The vibration support 22 is arranged at the bottom of the support beam 200 and the energy storage support 21, and includes: a first vibration block 220, a second vibration block 221, a fixing seat 222, and a spring group;

[0052] During the use of the device, the chute impacted by the material will continue to vibrate under the support of the spring. At the same time, during the vibration, the counterweight slider will slide along the guide shaft through the buffer spring. The impact of the counterweight slider will drive the counterweight beam to vibrate and generate kinetic energy. During the vibration process, the counterweight beam converts the kinetic energy into the kinetic energy of the counterweight slider and the potential energy of the spring and feeds it back to the chute, so that it keeps vibrating.
