Description

Technical Field

[0001] This utility model belongs to the technical field of screening devices, and specifically relates to a multi-stage banana screen. Background Technology

[0002] The banana screen is a high-efficiency vibrating screening device. Its unique arc-shaped screen design allows it to process large quantities of material, making it particularly suitable for screening high-moisture and viscous materials. It is widely used in mining, coal, chemical, food processing, environmental protection, and many other industries.

[0003] In existing banana screens, workers feed material into the screening mechanism via a feeding device. Large particles become trapped in the feeding mechanism, which has a primary screening structure. Workers then activate a pushing mechanism within the feeding mechanism to move these large particles to the discharge structure for cleaning. However, this cleaning method only effectively removes large particles above the filter screen; it fails to effectively remove large particles stuck in the filter pores. Over time, the amount of large particles trapped in the filter pores gradually increases, causing significant blockage and hindering effective cleaning. This severely impacts the effectiveness and efficiency of the primary screening of subsequent materials, thus affecting the overall screening effect and efficiency of the device. In such cases, workers often disassemble the feeding mechanism, clean the primary screening structure, and then reinstall it. This process is time-consuming, labor-intensive, and inefficient, failing to meet user needs. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing a multi-stage banana screen, which not only meets the requirements for material screening, but also concentrates large particles of material by setting an inclined screen plate, and then crushes the concentrated large particles of material by a crushing mechanism, avoiding the blockage of the screen mesh by large particles of material, saving time and labor, and improving processing efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a multi-stage banana screen, including a square frame, a frame body on the top of the square frame, multiple elastic mechanisms on the top of the frame body, a screening mechanism shared among the multiple elastic mechanisms, a feeding mechanism on the right side of the screening mechanism, the feeding mechanism including a cover body on the top right side of the screening mechanism, a first filter plate inclinedly arranged inside the right side of the cover body, a second filter plate horizontally arranged and connected to the first filter plate, a crushing mechanism on the top left side of the cover body, and a frame body including multiple support rods on the front and rear sides of the top of the square frame, the front side... A crossbar is provided between the two support rods and between the two support rods on the rear side. The elastic mechanism includes a top plate respectively set on the top of the support rods. Multiple springs are set on the top of the four top plates. Connecting plates connected to the springs are set on the upper part of the four top plates. The screening mechanism includes a box set between the four connecting plates. The box is connected to the cover. Reinforcing ribs connected to the box are set on the top of the four connecting plates. A discharge port is set at the bottom of the box. A discharge box corresponding to the discharge port is set at the bottom of the box. A discharge pipe is set at the bottom of the discharge box. Multiple filter plates are set inside the box.

[0006] As a further improvement of this utility model, the crushing mechanism includes a U-shaped plate set on the top of the cover, a guide seat set in the middle of the top of the U-shaped plate, a support plate set on the top of the U-shaped plate near the guide seat, a rotating shaft rotatably set on the front side of the support plate, a disc set on the front side of the rotating shaft, a column fixedly set on the top of the front side of the disc, a rotating rod rotatably set on the column, a U-shaped frame hinged to the end of the rotating rod away from the column, a guide rod passing through the guide seat at the bottom of the U-shaped frame, a pressure plate corresponding to the second filter plate at the bottom of the guide rod, a plurality of crushing heads at the bottom of the pressure plate, and a rotary motor connected to the rotating shaft set on the rear side of the support plate. The rotary motor and the rotating shaft are connected by a coupling.

[0007] As a further improvement of this utility model, a feeding hopper is provided on the top right side of the cover, a vibrator is provided on the front side of the box, a switch is provided on the front right end of the front support rod, the switch is electrically connected to the rotary motor and the vibrator, support legs are provided at the four corners of the bottom of the frame, and anti-slip pads are provided at the bottom of the four support legs, and a collection box corresponding to the discharge pipe is provided on the ground, with a handle on the left side of the collection box.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] Firstly, this design incorporates a rotary motor. The rotation of the rotary motor drives the rotating shaft to rotate, which in turn drives the rotating disc to rotate. The rotation of the disc drives the column on it to rotate the rotating rod. At this time, the U-shaped frame hinged to the rotating rod drives the guide rod to move up and down inside the guide seat. Meanwhile, the pressure plate at the bottom of the guide rod drives the crushing head at its bottom to move up and down, thereby crushing the large particles of material at the top of the filter plate and preventing the material from clogging the filter plate.

[0010] Secondly, this design includes a filter plate one. The inclined setting of filter plate one allows large particles in the material to roll to the top of filter plate two, thus facilitating the crushing of large particles.

[0011] Thirdly, this design incorporates multiple springs, which enhance the vibration effect of the screening mechanism and prevent vibration from being transmitted to the frame, thus protecting the frame.

[0012] Fourth, this design includes a collection box, which allows for better collection of materials after screening. Attached Figure Description

[0021] like Figure 1 , 3As shown in Figure 4, the crushing mechanism includes a U-shaped plate 105 disposed on the top of the cover 102. A guide seat 113 is disposed in the middle of the top of the U-shaped plate 105. A support plate 106 is disposed on the top of the U-shaped plate 105 near the guide seat 113.

A column 109 is fixedly disposed on the top of the front side of the disc 108. A rotating rod 110 is rotatably disposed on the column 109. A U-shaped frame 111 is hinged to the end of the rotating rod 110 away from the column 109. A guide rod 112 is disposed at the bottom of the U-shaped frame 111, passing through the guide seat 113. A pressure plate corresponding to the filter plate 104 is disposed at the bottom of the guide rod 112. 114, the bottom of the pressure plate 114 is provided with multiple crushing heads 115, the rear side of the support plate 106 is provided with a rotary motor 211 connected to the rotating shaft 107, the rotary motor 211 and the rotating shaft 107 are connected by a coupling, the screening mechanism includes a box 201 provided between four connecting plates 120, the box 201 is connected to the cover 102, the top of the four connecting plates 120 is provided with reinforcing ribs 202 connected to the box 201, the bottom of the box 201 is provided with a discharge port, the bottom of the box 201 is provided with a discharge box 203 corresponding to the discharge port, the bottom of the discharge box 203 is provided with a discharge pipe 204, and the inside of the box 201 is provided with multiple filter plates 205.

[0022] like Figure 1 As shown, a feeding hopper 206 is provided on the top right side of the cover 102, a vibrator 207 is provided on the front side of the box 201, a switch 208 is provided on the front side of the support rod 116 at the front right end, the switch 208 is electrically connected to the rotary motor 211 and the vibrator 207, support legs are provided at the four corners of the bottom of the frame 101, and anti-slip pads are provided at the bottom of the four support legs, and a collection box 209 corresponding to the discharge pipe 204 is provided on the ground, and a handle 210 is provided on the left side of the collection box 209.

[0023] How to use this utility model:

[0024] The operator first turns on switch 208, which then activates vibrator 207. The activation of vibrator 207 causes the housing 201 to vibrate. At this time, spring 119 on connecting plate 120 connected to housing 201 isolates the vibration force, so that the vibration force is concentrated at the top of support rod 116. The operator then adds material into the hopper 206. Under the action of gravity, the material falls onto filter plate 103 and slides, leaving excessive material at the top of filter plate 103. Other qualified material enters the housing 201 and the top of filter plate 205 under the action of gravity. At the same time, the material at the top of filter plate 103 slides downward to the top of filter plate 204, and then the following work begins.

[0025] When the rotary motor 211 is started, the rotation of the rotary motor 211 drives the rotary shaft 107 to rotate, the rotation of the rotary shaft 107 drives the disc 108 to rotate, the rotation of the disc 108 drives the column 109 on it to drive the rotary rod 110 to rotate. At this time, the U-shaped frame 111, which is hinged to the rotary rod 110, drives the guide rod 112 to move up and down inside the guide seat 113. At this time, the pressure plate 114 at the bottom of the guide rod 112 drives the crushing head 115 at its bottom to move up and down, thereby crushing the large particles of material at the top of the filter plate 2 104 until the particle size of the material is suitable and falls from the filter plate 2 104 into the inside of the box 201.

[0026] Meanwhile, the material falls onto the filter plate 205, which separates the material, causing smaller materials to fall downwards, larger materials to be discharged through the opening on the left, and smaller materials to be discharged through the discharge port, the discharge box 203, and finally from the discharge pipe 204 into the collection box 209.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
