Description

Technical Field

[0001] The invention relates to a device for lifting materials, in particular to a hopper of an elevator. Background Art

[0002] Hoists are widely used in mines, docks, granaries and other places.

[0003] Bucket elevator is a transportation equipment specially used for continuous vertical transportation of materials. After the transmission mechanism is started, it drives the head wheel to make the chain circulate from bottom to top. Through the bucket fixed on the chain, the material filled in the bucket is lifted from the bottom of the elevator to the head of the elevator, so that the material is thrown out of the bucket under the action of centrifugal force. The empty bucket returns to the bottom of the elevator through the chain, and is lifted up and thrown out after being filled with materials. This cycle is repeated to lift the bottom material to the specified height to meet the requirements of vertical transportation.

[0004] This traditional elevator structure is very mature and is widely used in various industries for lifting operations. However, for the application of some special materials, the traditional elevator has some technical defects that have not been overcome so far.

[0005] For example, in most materials, there are always small particles mixed in. These small particles are easy to cause the phenomenon of aggregation in the hopper, which limits the outflow speed of the material in the hopper, easily causes the hopper to be blocked, and reduces the conveying efficiency. In particular, silt materials, sticky materials and materials with high water content are easy to adhere to the inner wall of the hopper and are not easy to fall off, which not only reduces the conveying efficiency, but also increases energy consumption.

[0006] At present, although colleagues in the industry have also noticed this problem and are constantly making various structural improvements, there have been no reports of substantial improvements so far. Summary of the invention

[0007] The object of the present invention is to provide a hopper of an elevator, which can greatly reduce the adhesion of materials on the inner wall of the hopper, thereby improving the conveying efficiency, reducing energy consumption and saving costs.

[0008] The technical solution of the present invention is: comprising a hopper body, two side plates of the hopper body are provided with slide grooves, slide rods are embedded in the slide grooves, and the slide rods are movably matched with the slide grooves.

[0009] The diameter of the middle section of the slide stick is larger than the width of the slide slot, and the diameters of the two ends of the slide stick are smaller than the width of the slide slot. The two ends of the slide stick are located in the slide slot and movably cooperate with the slide slot.

[0010] A limiting device is embedded in the top of the slide groove.

[0011] After all the slide rods are embedded in the slide groove, space is left in the slide groove to ensure the movement of the slide rods.

[0012] The limiting device can be replaced by a combination of bolts and nuts.

[0013] In the present invention, slide grooves are arranged on both side plates of the hopper body, slide rods are embedded in the slide grooves, the slide rods and the slide grooves are movably matched, all the slide rods embedded in the slide grooves constitute the front plate of the hopper, and space is reserved in the slide grooves to ensure the movement of the slide rods.

[0014] When the hopper circulates up and down to transport materials, the slide rods slide up and down in the chute under the action of gravity, and the slide rods collide with each other, causing vibration; at the same time, when the hopper scoops materials, the materials enter the hopper from the upper edge of the front plate, and the materials rub against the slide rods, pushing all the slide rods to rotate around their own axes. Due to the different density and particle size of the materials, the friction force on each slide rod is different, and the rotation speed of the slide rods is also different. Each slide rod rotates relative to each other, and the materials stuck on the slide rods will be scraped off by each other. When the hopper dumps the materials, the materials will also rub against the slide rods to rotate, but the direction of rotation is exactly opposite to that when the materials are scooped in, and the materials still remaining on the slide rods will be scraped again. Therefore, the slide rods undergo collision vibration and rotation scraping in both positive and negative directions during the entire operation, so as to maximize the shedding of fine materials and sticky materials stuck to the slide rods.

[0015] For materials with a lot of water, especially materials scooped up from water, a large amount of water will be quickly discharged from the gaps between the slide bars, which has a unique effect on lifting materials soaked in water, which is unmatched by traditional hoppers.

[0016] Compared with the traditional hopper, the hopper of the present invention greatly reduces the sticky materials and can quickly drain water, thereby increasing the effective volume of the hopper for loading materials and reducing the empty weight of the hopper, thereby improving the transportation efficiency and reducing energy consumption.

[0017] In the present invention, the sliding rod and the material are mostly rolling friction, and the material wear is smaller than the sliding friction of the traditional hopper, and the part with greater wear is mainly the front plate. The present invention adopts a sliding rod to form the front plate. When the sliding rod is worn out and cannot be used anymore, it can be easily replaced, which prolongs the service life of the hopper, saves materials, and reduces the use cost of the hopper. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 2 It is a structural schematic diagram of the sliding rod in the present invention. DETAILED DESCRIPTION

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but they do not constitute any limitation to the present invention.

[0021] Figure 1 and Figure 2 As shown, the present invention includes a hopper body 1, and a slide groove is provided on both side plates of the hopper body 1, and a slide rod 2 is embedded in the slide groove. The diameter of the middle section of the slide rod 2 is greater than the width of the slide groove, and the diameter of the two ends of the slide rod 2 is less than the width of the slide groove. The two ends of the slide rod 2 are located in the slide groove and cooperate with the slide groove. Since the middle diameter of the slide rod is greater than the width of the slide groove, it will not fall out of the slide groove. All the slide rods 2 loaded into the slide groove constitute the front plate of the hopper. A certain space should be reserved in the slide groove for the slide rod 2 to move. The slide rod 2 not only slides in the slide groove, but also rotates around the axis of the slide rod 2. In order to prevent the slide rod 2 in the slide groove from falling out of the slide groove, a limit device 3 needs to be installed on the top of the slide groove after the slide rod 2 is installed. The purpose is to occupy the slide groove space, reduce the length of the slide groove, and prevent the slide rod 2 from falling out of the slide groove. The limit device 3 can be adopted in a variety of ways. In this embodiment, the structure of bolts and nuts is more convenient and reliable. It only needs to insert the bolts into the slide groove and tighten them with nuts.

[0022] During installation, insert both ends of the slide stick 2 into the slide slot. Since the total length of the slide stick 2 is greater than the distance between the inner walls of the two side plates of the hopper, one end of the slide stick 2 should be high and the other end should be low when it is installed, and it can be installed in an inclined state. Finally, bolts and nuts are installed at the top of the slide slot to occupy the space of the slide slot so that the slide stick 2 cannot fall out. The other installations of the hopper and the installation of the whole machine are the same as the existing traditional hopper installation methods, which will not be repeated here.

[0023] During operation, the front plate of the hopper scoops up materials and pours out materials, so the front plate and materials frequently rub against each other, causing great wear and tear on the front plate. After using a traditional hopper, the inner wall of the front plate will be worn very smooth, and the smooth inner wall is very easy to adhere to materials, especially small and wet materials. Some highly sticky materials stick to the hopper for a long time and are difficult to fall off, which not only affects work efficiency, but also greatly increases energy consumption. In the present invention, when the hopper circulates up and down to transport materials, the slide rod 2 slides up and down in the chute under the action of gravity. When loading materials, the hopper mouth gradually turns upward, and the slide rod 2 slides downward under the action of gravity. The slide rods 2 collide with each other, generating vibrations, thereby vibrating the materials stuck to the slide rod 2. At the same time, when the material enters the hopper from the upper edge of the front plate, the material rubs against the slide rod 2, pushing all the slide rods 2 to rotate around their own axis. Due to the different density and particle size of the material, the friction force on each slide rod 2 is different, and the rotation speed of the slide rod 2 is also different. Each slide rod 2 rotates relative to each other, and the material stuck on the slide rod 2 will be scraped off by each other. When the hopper dumps the material, the material will also rub against the slide rod 2 to rotate, but its rotation direction is exactly opposite to that when the material is scooped in, and the material still remaining on the slide rod 2 will be scraped again. At the same time, the hopper mouth gradually turns downward, and the slide rod 2 slides toward the hopper mouth under the action of gravity. Therefore, the slide rods 2 collide again, generate vibration, and continue to vibrate the material stuck on the slide rod 2. In a complete workflow, the slide rod 2 undergoes collision, vibration, and rotation and scraping of the slide rod in both the forward and reverse directions, so that the fine materials and sticky materials stuck on the slide rod 2 fall off to the greatest extent. For materials with a lot of water, especially materials soaked in water after rain, when scooping up the materials in the water, the water will be quickly discharged from the gap between the slide bars 2, which has a unique effect on lifting the materials soaked in water, which is unattainable by traditional hoppers.

[0024] Compared with the traditional hopper, the hopper of the present invention greatly reduces the adhesion of materials and retained water, increases the effective volume of the hopper for loading materials, reduces the empty weight of the hopper, thereby improving the conveying efficiency and reducing energy consumption. In the present invention, the sliding rod 2 and the material are mostly rolling friction, and the wear of the material is smaller than the sliding friction of the traditional hopper, and the part with greater wear is mainly on the front plate. The present invention uses the sliding rod 2 to form the front plate. When the sliding rod 2 is worn out and cannot be used anymore, it can be easily replaced, which prolongs the service life of the hopper, saves materials, and reduces the use cost of the hopper.
