Technical Field
[0001] The invention relates to a feeding device, in particular to an automatic feeding device for a screening machine. Background Art
[0002] In industrial production, screening machines, as key materials handling equipment, are widely used in numerous industries, including mining, chemicals, building materials, and food. Their primary function is to separate materials of varying particle sizes to meet the requirements of subsequent production processes. The loading process of a screening machine is a crucial beginning of the entire production process, and its efficiency and stability directly impact its performance and production efficiency.
[0003] Traditional methods of feeding screening machines mostly rely on manual feeding or simple mechanical conveying devices. Manual feeding has problems such as high labor intensity, low efficiency, and uneven material delivery, making it difficult to meet the needs of large-scale industrial production. Simple mechanical conveying devices, such as belt conveyors, although they have improved the feeding efficiency to a certain extent, have shortcomings such as complex equipment structure, large floor space, and poor adaptability to materials. For example, for some materials with high viscosity or high moisture content, belt conveyors are prone to problems such as material adhesion and blockage, affecting the continuity of feeding. In addition, traditional feeding devices are difficult to accurately control the feeding speed and flow rate, and cannot be adjusted in real time according to the working status of the screening machine, resulting in unstable screening effect.

[0014] The advantages of the present invention compared with the prior art are:
[0015] In the present invention, after the material enters the feeding device, the bottom corrugated plate is used to evenly disperse the material in the trough under the action of vibration force. Then, under the action of the water medium, the material is in a semi-floating state, which reduces friction. Then, the vibration motor at the bottom of the feeding device cooperates with the vibration screen's own vibration source to transmit the exciting force to the feeding device, allowing the material to semi-float in the water and move in a linear state. The bottom of the hopper is composed of a flat plate connected to a corrugated plate, which solves the problem of material residue and makes the material run smoother, thereby achieving true automatic feeding and improving work efficiency.
[0016] The angle adjustment assembly of the present invention adopts the structure of threaded rod and adjustment rod, and the angle of the feeding frame can be flexibly adjusted through a simple rotation operation; this design enables the device to adapt to materials with different characteristics and has strong versatility and adaptability.
[0017] The adjustable baffle plate can adjust the height of the baffle plate body and thus adjust the discharge amount by locking the skewers and adjusting the slide; the guide plates on both sides of the discharge channel can also make the material converge to the middle, which is convenient for guiding and discharging.
[0018] The flat plate, corrugated plate and the load-bearing plate are detachably connected by bolts, making equipment maintenance and component replacement more convenient and quick. During long-term use, when the flat plate or corrugated plate is worn or damaged, it can be quickly disassembled and replaced with a new part, reducing equipment downtime and improving production efficiency.

The corrugated plate 3 includes an edge mounting plate 301 connected to the supporting plate 13. Several upwardly protruding triangular plates 302 are connected end to end between the edge mounting plates 301, and a material feeding channel is formed between adjacent triangular plates 302. A vibration motor 7 is provided at the bottom of the corrugated plate 3. A water supply pipe 8 is provided at the upper part of the end of the feeding frame 1 away from the discharge channel 4 along the length direction of the flat plate 2. The water supply pipe 8 is located on the inner part of the feeding frame 1 and has several water outlet holes 9 at its bottom. One end of the water supply pipe 8 passes through the feeding frame 1 and is connected to the end closure sleeve 14. The other end is connected to an external water supply source through a water pipe joint.
[0034] The feeding frame 1 is provided with a rotating seat 10 that is rotatably connected to the two ends of the screen surface of the screening machine at one end near the unloading channel 4, and an angle adjustment component 11 is provided at the other end. A support rod 12 is rotatably provided at the other end of the angle adjustment component 11, and the other end of the support rod 12 is fixed to the screening machine; the angle adjustment component 11 includes a threaded rod 1101 and a threaded rod 2 1102 that are arranged oppositely.

[0035] The adjustable baffle plate 5 includes a baffle plate body 501, and adjustment slides 502 are vertically arranged at both ends of the baffle plate body 501. An L-shaped mounting bracket 503 connected to the baffle plate body 501 is arranged on the inner wall of the feeding frame 1, and a locking bolt 504 connected to the adjustment slide 502 is arranged on the mounting bracket 503.
[0036] The bottom of the loading frame on both sides of the discharge channel is further provided with inclined guide plates 15 .
[0037] The operation process of this embodiment:
[0038] The bottom of the feeding frame is rotatably connected to the two ends of the screen surface of the rotating seat screening machine, which serves as a fulcrum for adjusting the inclination. Its inclination is an adjustable range of 0-35 degrees between the bottom of the hopper and the screen surface. In some embodiments, the inclination angle of the feeding frame can also be set to a fixed type according to specific needs; when adjusting the angle, the adjusting rod is rotated. Since the threaded rod one and the threaded rod two have opposite rotation directions, the threaded rod one and the threaded rod two will move in opposite directions at the same time, thereby changing the inclination angle of the feeding frame; through the angle adjustment component, the angle of the feeding frame can be flexibly adjusted according to the working requirements of the screening machine and the characteristics of the material, so as to optimize the material conveying speed and screening effect.
[0039] One end of the flat plate contacts the inner wall of the feeding frame, and the other end is connected to the corrugated plate to form an inclined material carrying surface. The material enters the feeding cavity of the feeding frame from above and first falls on the flat plate. The upper water pipe sprays an appropriate amount of water into the upper feeding cavity, so that the material is in a semi-floating state under the action of the water medium, reducing friction, so as to facilitate subsequent screening operations; after the vibration motor set at the bottom of the corrugated plate is started, it generates vibration and transmits it to the corrugated plate. The vibration of the corrugated plate cooperates with the vibration source of the screening machine itself to transmit the exciting force to the feeding device, so that the material is semi-floating in the water and moves in a linear state, so that the material moves along the material feeding channel to the downward channel; when the material is transported to the end of the corrugated plate, it is blocked by the adjustable baffle plate and can only be discharged evenly from the discharging channel, thereby controlling the discharging speed and flow of the material, ensuring that the material can be evenly distributed on the screen surface of the screening machine, and improving the screening efficiency and screening quality;
[0040] In addition, by loosening the locking bolts, the height of the baffle plate body can be adjusted up and down, and then the distance between the bottom of the baffle plate body and the corrugated plate can be adjusted to adjust the discharge amount. The guide plates on both sides of the discharge channel can also make the material converge to the middle, which is convenient for guiding and discharging.
[0041] Example 2:
[0042] Combined with attachment Figure 8 The difference between this embodiment and embodiment 1 is that, in this embodiment, the loading plate is only set as a corrugated plate 3.
