Description

Technical Field

[0001] This utility model relates to the field of material transport equipment, and in particular to a feeding device for a tractor belt scale. Background Technology

[0002] In industries such as metallurgy, coal mining, and cement, tractor belt scales, through the integration of mechanical structure and intelligent algorithms, have become key equipment for handling industrial bulk materials, balancing the needs of high-precision measurement and efficient production.

[0003] One end of a tractor belt scale is usually equipped with a feeding hopper, which works in conjunction with the feed belt. During production and transportation, the feed belt continuously feeds materials into the feeding hopper, which then guides the materials onto the belt of the tractor belt scale for weighing and transmission. However, after prolonged use, tractor belt scales may develop error problems, so users often need to calibrate them.

[0004] In the prior art, when calibrating a tractor belt scale, it is necessary to ensure that there is no residual material on the tractor belt scale. Therefore, the slide valve of the feed hopper is closed to prevent material in the feed hopper from continuing to enter the tractor belt scale.

[0005] However, after prolonged use, the slide gate valve of the feed hopper may malfunction or become loosely sealed, causing continuous material leakage from the feed hopper onto the tractor belt scale, thus hindering the calibration of the tractor belt scale. Utility Model Content

[0006] This utility model provides a feeding device for a tractor belt scale. It eliminates the need for a slide valve and simply uses a material feeding chamber, a material storage arc groove, and a material feeding assembly inside the feeding box to prevent material leakage from the feeding box when the material feeding assembly is not in motion, thereby improving the calibration efficiency of the tractor belt scale.

[0007] To achieve the above objectives, this utility model provides a feeding device for a tractor belt scale, comprising:

[0008] Support side panels;

[0009] The feeding box has supporting side plates on both sides, which are mounted on the transmission frame of the tractor belt scale. The feeding box is located above the tractor belt scale. The feeding box has an inlet and an outlet. Inside the feeding box, from top to bottom, there are interconnected feeding chamber, pushing chamber, and discharging chamber. The feeding inlet is connected to the feeding chamber, and the discharging outlet is connected to the discharging chamber. A material storage arc groove is provided in the pushing chamber.

[0010] A feeding assembly is disposed within the feeding chamber. The feeding assembly includes a feeding shaft and multiple feeding blades. The feeding shaft is rotatably disposed within the feeding chamber. One end of the feeding shaft extends out of the feeding box. The multiple feeding blades are circumferentially disposed on the outer circumferential wall of the feeding shaft. The feeding blades cooperate with the material storage arc groove.

[0011] Furthermore, the feeding box is L-shaped, and the discharge chamber and the pushing chamber are inclined.

[0012] Furthermore, the pusher blades are arc-shaped.

[0013] Furthermore, a discharge slant is provided at the discharge port.

[0014] Furthermore, the feeding device for the belt conveyor also includes an anti-blocking component, which is disposed at the connection between the feeding chamber and the pushing chamber. The anti-blocking component includes a baffle plate, a tilting shaft, and multiple tilting blades. The baffle plate is disposed at the top of the pushing chamber and is located above the pushing component. The tilting shaft is rotatably disposed in the feeding chamber and is close to the pushing component. One end of the tilting shaft extends out of the feeding box. The multiple tilting blades are circumferentially disposed on the outer circumferential wall of the tilting shaft.

[0015] Furthermore, the feeding device for the belt conveyor also includes a pusher motor and a tilter motor. Both the pusher motor and the tilter motor are fixedly mounted on the outer walls of both sides of the feeding box. The output end of the pusher motor is rotatably connected to one end of the pusher shaft, and the output end of the tilter motor is rotatably connected to one end of the tilter shaft.

[0016] Furthermore, the feeding device for the belt conveyor also includes a scraper assembly. The scraper assembly is rotatably disposed on the outer wall of the feeding box near the discharge port. The scraper assembly includes a propulsion cylinder, a linkage component, and a scraper. The propulsion cylinder is fixedly disposed on the outer wall of the feeding box. The linkage component includes a first rotating plate, a linkage rod, and a second rotating plate. The first rotating plate and the second rotating plate are respectively rotatably disposed on the outer wall of the feeding box near the discharge port. The linkage rod is disposed between one end of the first rotating plate and one end of the second rotating plate. The scraper is disposed between the other end of the first rotating plate and the other end of the second rotating plate. The output end of the propulsion cylinder is provided with a rotating groove. A rotating column is disposed in the rotating groove. One end of the first rotating plate is rotatably engaged with the rotating column.

[0017] Preferably, the scraper is provided with a scraping bevel.

[0018] Furthermore, the feeding device for the belt conveyor also includes a guide plate, which is located on the inner wall of the feeding chamber near the pushing chamber and is positioned directly above the tilting shaft.

[0019] Compared with the prior art, a feeding device for a tractor belt scale according to an embodiment of the present invention has an infeed chamber, a pushing chamber and a discharge chamber that are interconnected from top to bottom in the feeding box. The pushing chamber is provided with a material storage arc groove, and the pushing component is disposed in the pushing chamber and cooperates with the material storage arc groove. When the pushing component is closed, it can prevent material from entering the discharge chamber from the infeed chamber, preventing material from falling onto the belt of the tractor belt scale and improving the calibration speed of the tractor belt scale. When the pushing component is open, it can assist the material to enter the discharge chamber, realizing timely feeding. Attached Figure Description

[0033] To provide a better understanding of the purpose, structure, features, and functions of this utility model, detailed descriptions are provided below with reference to specific embodiments.

[0034] like Figures 1-5 As shown, a feeding device for a tractor belt scale according to an embodiment of the present invention includes:

[0035] Support side plate 1000, feed box 2000, and pusher assembly;

[0036] The feeding box 2000 is provided with support side plates 1000 on both sides, and the support side plates 1000 are set on the transmission frame of the tractor belt scale 1100. The feeding box 2000 is located above the tractor belt scale 1100. The feeding box 2000 has a feed inlet 2100 and a discharge outlet 2200. The feeding box 2000 has interconnected feed chamber 2300, push chamber 2400 and discharge chamber 2500 from top to bottom. The feed inlet 2100 is connected to the feed chamber 2300, and the discharge outlet 2200 is connected to the discharge chamber 2500. The push chamber 2400 has a material storage arc groove 2410.

[0037] The feeding assembly is set inside the feeding cavity 2400. The feeding assembly includes a feeding shaft 3100 and multiple feeding blades 3200. The feeding shaft 3100 is rotatably set inside the feeding cavity 2400. One end of the feeding shaft 3100 extends out of the feeding box 2000. The multiple feeding blades 3200 are circumferentially arranged on the outer circumferential wall of the feeding shaft 3100. The feeding blades 3200 cooperate with the material storage arc groove 2410.

[0038] The upper feeding device 1200 transmits the material to the feeding device of the tractor belt scale of this utility model. The material falls from the inlet 2100 into the feeding chamber 2300, and then from the feeding chamber 2300 into the pushing chamber 2400. At this time, the material preferentially enters the storage arc groove 2410. At the same time, the pushing component is started, and the pushing shaft 3100 rotates, driving the pushing blade 3200 counterclockwise. One end of the pushing blade 3200 cooperates with the arc surface of the storage arc groove 2410, so that the pushing blade 3200 scrapes the material in the storage arc groove 2410 and moves it towards the discharge chamber 2500. The material will fall from the discharge port 2200 onto the belt of the tractor belt scale 1100. At this time, the tractor belt scale 1100 is in working condition and weighs the falling material.

[0039] However, when the user needs to calibrate the tractor belt scale 1100, the user closes the upper feeding device 1200 and simultaneously closes the pushing component. The pushing component no longer pushes the material from the storage arc groove 2410 to the discharge chamber 2500, but the feed inlet 2100 of the feed box 2000 continues to receive the remaining material on the feeding belt. The material falling into the feed box 2000 will preferentially enter the storage arc groove 2410. At this time, multiple stopped pushing blades 3200 will block the material, so that the material is always in the storage arc groove 2410, thereby preventing the material from leaking onto the belt of the tractor belt scale 1100, making it convenient for the user to calibrate the tractor belt scale 1100, and avoiding material waste.

[0040] Furthermore, such as Figure 1 and Figure 2 As shown, the feed box is L-shaped, and the discharge chamber 2500 and the push chamber 2400 are inclined. The material enters the feed chamber 2300 through the feed inlet 2100 and then enters the push chamber 2400. The material moves in the inclined push chamber 2400 and discharge chamber 2500 according to its own gravity, which avoids the accumulation of material during discharge.

[0041] Furthermore, such as Figure 4 and Figure 5 As shown, the pusher blade 3200 is arc-shaped. The arc-shaped pusher blade 3200 can push the material in the storage arc groove 2410 to the maximum extent, and the arc-shaped part of the pusher blade 3200 helps the pusher blade 3200 to operate.

[0042] Furthermore, such as Figure 1 As shown, a discharge inlet 2210 is provided at the discharge port 2200. The discharge inlet 2210 further assists in the discharge of materials during material unloading.

[0043] Furthermore, such as Figure 4 and Figure 5As shown, the feeding device for the conveyor belt scale also includes an anti-blocking component. The anti-blocking component is located at the connection between the feeding chamber 2300 and the pushing chamber 2400. The anti-blocking component includes a baffle plate 4100, a tilting shaft 4200, and multiple tilting blades 4300. The baffle plate 4100 is located at the top of the pushing chamber 2400 and above the pushing component. The tilting shaft 4200 is rotatably mounted within the feeding chamber 2300, close to the pushing component. One end of the tilting shaft 4200 extends out of the feeding box 2000. Multiple tilting blades 4300 are circumferentially arranged on the outer circumferential wall of the tilting shaft 4200. When the pushing component is in the closed state, material accumulates in the storage arc groove 2410. To prevent the material accumulation height from exceeding the pushing blades 3200, the anti-blocking component is installed to prevent material from overflowing the pushing blades 3200, thus assisting the user in verifying the conveyor belt scale 1100.

[0044] The anti-blocking component includes a baffle plate 4100 to intercept materials and prevent them from overflowing the pusher blades 3200 and entering the discharge chamber 2500. The anti-blocking component also includes a turning shaft 4200 and multiple turning blades 4300 to turn over accumulated materials. Simultaneously, the pusher blades 3200 block some materials from entering the storage chute, further reducing material accumulation at the connection between the feed chamber 2300 and the pusher chamber 2400. This also prevents the pusher component from malfunctioning due to the large load generated by the material at the pusher blades 3200 when it restarts. Before the pusher component restarts, the turning shaft 4200 rotates clockwise, driving the turning blades 4300 to turn over the material accumulated at the connection between the feed chamber 2300 and the pusher chamber 2400, allowing some material to move away from the pusher component, facilitating its movement and extending its service life.

[0045] Preferably, the rotation direction of the turning shaft 4200 is always opposite to the rotation direction of the pushing shaft 3100.

[0046] Furthermore, such as Figure 1 As shown, the feeding device for the belt conveyor also includes a pusher motor 5100 and a tilter motor 5200. Both the pusher motor 5100 and the tilter motor 5200 are fixedly mounted on the outer walls of both sides of the feeding box 2000. The output end of the pusher motor 5100 is rotatably connected to one end of the pusher shaft 3100, and the output end of the tilter motor 5200 is rotatably connected to one end of the tilter shaft 4200. Both the pusher motor 5100 and the tilter motor 5200 are existing high-load motors.

[0047] Furthermore, such as Figure 1 , Figure 2 and Figure 3As shown, the feeding device for the belt conveyor also includes a scraper assembly 6000. The scraper assembly 6000 is rotatably mounted on the outer wall of the feeding box 2000 near the discharge port 2200. The scraper assembly 6000 includes a propulsion cylinder 6100, a linkage component, and a scraper 6300. The propulsion cylinder 6100 is fixedly mounted on the outer wall of the feeding box 2000. The linkage component includes a first rotating plate 6210, a linkage rod 6220, and a second rotating plate 6230. The first rotating plate 6210 and the second rotating plate 6230... The first rotating plate 6210 and the second rotating plate 6230 are respectively rotatably mounted on the outer wall of the feed box 2000 near the discharge port 2200. A linkage rod 6220 is set between one end of the first rotating plate 6210 and the second rotating plate 6230. A scraper 6300 is set between the other end of the first rotating plate 6210 and the other end of the second rotating plate 6230. A rotating groove 6110 is set at the output end of the propulsion cylinder 6100. A rotating column 6111 is set in the rotating groove 6110. One end of the first rotating plate 6210 is rotatably engaged with the rotating column 6111. When the material contains dust and sticky impurities, these dust or sticky impurities will adhere to the belt of the tractor belt scale 1100 and accumulate in large quantities over time, thus affecting the accuracy of the tractor belt scale 1100. Therefore, by setting up the scraper assembly 6000, the impurities on the belt are scraped off during the calibration of the tractor belt scale 1100, thereby improving the accuracy of the tractor belt scale 1100.

[0048] The specific working principle of the scraper assembly 6000: as follows Figure 2 and Figure 4 As shown, the propulsion cylinder 6100 is in the extended state. The output end of the propulsion cylinder 6100 pushes one end of the first rotating plate 6210 to rotate clockwise, causing the other end of the first rotating plate 6210 to rotate clockwise synchronously. At the same time, one end of the first rotating plate 6210 rotates in the rotating groove 6110 through the rotating shaft, avoiding material collision between one end of the first rotating plate 6210 and the output end of the propulsion cylinder 6100. At this time, the second rotating plate 6230 rotates synchronously through the linkage rod 6220, thereby rotating the scraper 6300 that contacts the bottom of the feed box 2000 clockwise, so that the scraper 6300 contacts the belt of the tractor belt scale 1100. At this time, it is necessary to ensure that the belt of the tractor belt scale 1100 is rotating counterclockwise, so that the scraper 6300 cooperates with the belt, thereby scraping off the impurities attached to the belt. After scraping is completed, the propulsion cylinder 6100 returns to the initial state. Figure 5 As shown, the output end of the propulsion cylinder 6100 pulls the first rotating plate 6210 to rotate counterclockwise. The first rotating plate 6210 then drives the second rotating plate 6230 to rotate counterclockwise synchronously through the linkage rod 6220. At the same time, the scraper will rotate counterclockwise, causing the scraper to move closer to the outlet of the feed box 2000. At this time, the belt of the drag belt scale 1100 will rotate and discharge the scraped impurities from the belt.

[0049] Furthermore, such as Figure 4 As shown, the scraper 6300 is equipped with a scraping bevel. The scraping bevel has an incline to help scrape away impurities.

[0050] Furthermore, such as Figure 4 and Figure 5 As shown, the feeding device for the belt conveyor also includes a guide plate 7000. The guide plate 7000 is located on the inner wall of the feed chamber 2300 near the push chamber 2400, and is directly above the tilting shaft 4200. When material enters the feed chamber 2300, it first falls onto the guide plate 7000, which is tilted to assist the material in moving under its own weight, preventing it from falling directly into the push chamber 2400 and ensuring the normal operation of the tilting shaft 4200 and the tilting blades 4300.
