DETAILED DESCRIPTION

[0025] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, a high-frequency vibration conveyor includes an exciter 1, a combined elastic unit 2, a frame 3, a vibration conveying trough 4 and a supporting device 5. The vibration conveying trough 4 is connected to the frame 3 through a plurality of combined elastic units 2. The vibration conveying trough 4 is used to convey materials. The exciter 1 is installed on the frame 3 to drive the frame 3 to vibrate. When the frame 3 vibrates, the vibration is transmitted to the vibration conveying trough 4 through the combined elastic unit 2, so that the vibration conveying trough 4 vibrates. The supporting device 5 is installed at the bottom of the frame 3 to provide supporting force. At the same time, the supporting device 5 is flexibly connected to the frame 3, which can reduce the transmission of dynamic load to the ground.

[0027] Combination Figure 4 As shown, specifically, the combined elastic unit 2 includes at least a leaf spring 21 and a coil spring 22. The leaf spring 21 is tilted relative to the vibration conveying trough 4, the central axis of the coil spring 22 is arranged at an angle with the mounting surface of the leaf spring 21, and the two ends of the leaf spring 21 and the coil spring 22 are respectively connected to the vibration conveying trough 4 and the frame 3 through a connecting frame.

[0028] When the frame 3 vibrates, the leaf spring 21 and the coil spring 22 will vibrate together and transmit the vibration to the vibration conveying trough 4. The leaf spring 21 constrains the vibration direction of the vibration conveying trough 4 due to its geometric shape characteristics, so that it can only do forward and backward and up and down working movements, and will not shake left and right. Its disadvantages are high material costs and relatively poor durability. The advantages of the coil spring 22 are low manufacturing costs and durability. Its disadvantage is that because it is wound with a steel wire spiral, the freedom of movement is too large and it cannot be used alone as a main vibration spring. Combining the leaf spring 21 and the coil spring 22 into an elastic unit is a combination that brings out the advantages of each.

[0029] Preferably, the vibration exciters 1 are in pair and are symmetrically mounted on both sides of the frame 3 .

[0030] Specifically, the supporting device 5 includes a rigid supporting leg 51 and an elastic supporting body 52 . The elastic supporting body 52 is installed on the top of the rigid supporting leg 51 , and the top of the elastic supporting body 52 is connected to the frame 3 .

[0031] Specifically, the connecting frame includes an upper connecting frame 23 and a lower connecting frame 24, the upper connecting frame 23 is fixedly connected to the vibrating conveying trough body 4, the lower connecting frame 24 is fixedly connected to the frame 3, the upper connecting frame 23 is provided with a first mounting portion 23a, the upper ends of the leaf spring 21 and the coil spring 22 are connected to the first mounting portion 23a, the lower connecting frame 24 is provided with a second mounting portion 24b and a third mounting portion 24c, the lower end of the leaf spring 21 is connected to the second mounting portion 24b, and the lower end of the coil spring 22 is connected to the third mounting portion 24c.

[0032] The first mounting portion 23a, the second mounting portion 24b, and the third mounting portion 24c are distributed in a triangular shape. The first mounting portion 23a, the second mounting portion 24b, and the third mounting portion 24c are provided with screw holes / bolt holes, and the leaf spring 21 and the coil spring 22 are connected to the screw holes / bolt holes of the first mounting portion 23a, the second mounting portion 24b, and the third mounting portion 24c through screws / bolts.

[0033] Preferably, the central axis of the coil spring 22 is arranged perpendicularly to the mounting surface of the leaf spring 21. The main axis of the vibration exciter 1 is arranged perpendicularly to the central axis of the coil spring 22.

[0034] The bottom of the vibrating conveying trough 4 is a flat plate or a sieve plate. When only materials need to be conveyed, the bottom of the vibrating conveying trough 4 is a flat plate. When materials need to be screened while conveying materials, the bottom of the vibrating conveying trough 4 is a sieve plate. One end of the vibrating conveying trough 4 is a feeding end, and the other end is a discharging end. A feeding device 100 is provided at the feeding end, and a discharging device 200 is provided at the discharging end.

[0035] The working principle of the utility model is as follows: under the action of the exciting force of the vibrator 1, the frame 3 generates a vibration of a certain amplitude, driving the combined elastic unit 2 installed thereon to generate resonance. Due to the geometric characteristics (length) and elastic characteristics (material) of the combined elastic unit 2, the amplitude of the other end of the combined elastic unit 2 is naturally amplified several times. The amplified vibration and amplitude are transmitted to the vibration conveying trough 4, so that it reaches a state of near-same frequency resonance with the frame 3. According to vibration theory, when the vibration frequency enters the resonant state, the energy consumption of the external input is minimized.

[0036] In addition, since the central axis of the coil spring 22 is perpendicular to the main axis of the exciter 1 and is at a certain angle to the vibrating conveying trough 4, its vibration has a forward and upward synthetic acceleration, which drives the material in the vibrating conveying trough 4 to be thrown and conveyed in a directional manner.

[0037] The above is an implementation mode of the present invention. It should be pointed out that, for ordinary technicians in this field, various modifications and improvements can be made without departing from the principle of the present invention, which should also be regarded as the protection scope of the present invention.
