[0028] Example 1

[0029] A device for preventing the material from being blocked, such as Figure 1 、 Figure 2 and Figure 3 As shown, it includes a leaker 1, a feed port is provided at the top of the leaker 1, a discharge port is provided at the bottom of the leaker 1, a discharge pipe 2 is fixed at the discharge port, a plurality of slots 3 are symmetrically provided on the top of the left and right side walls of the leaker 1, the top of the slot 3 is open, the two ends of the connecting rod 4 are respectively placed in the two opposite slots 3, a baffle 5 is provided at the bottom of the connecting rod 4, the bottom end of the baffle 5 extends into the discharge pipe 2, and the length of the baffle 5 can be designed according to actual use needs so that the bottom end of the baffle 5 is flush with the bottom end of the discharge pipe 2 or extends out of the feed pipe 2.

[0030] The drain 1 in the present invention adopts the square drain in the prior art. The size of the drain 1 gradually decreases from the feed port to the discharge port. The cross-sectional shape of the drain 1 is square, and the cross-sectional shape of the discharge pipe 2 is also square. In this embodiment, the cross-sectional shape of the drain 1 and the cross-sectional shape of the discharge pipe 2 are both rectangular. The connecting rod 4 is placed along the length direction of the drain 1. Figure 3 As shown, the left and right side walls of the baffle 5 are in contact with the left and right inner walls of the discharge pipe 2. The thickness of the baffle 5 is smaller than the width of the discharge pipe 2.

[0031] The baffle 5 in this embodiment is made of a high-strength, highly elastic rubber material. It is secured to the connecting rod 4. The number of slots 3 can be adjusted based on the width of the discharge pipe 2, and the spacing between adjacent slots 3 can be adjusted based on the diameter or width of the connecting rod 4. The connecting rod 4 is longer than the length of the feed port of the drain 1 and can be round or square in shape.

[0032] The method of using the anti-clogging discharge leak device provided in this example is as follows: when in use, place the connecting rod 4 between the two opposite slots 3 so that the bottom end of the baffle 5 extends into the discharge pipe 2. The discharge space of the discharge pipe 2 is divided into two parts. Pour the material into the leak 1. The material can enter the leak 1 from directly above the baffle 5, or enter the leak 1 from one side or both sides of the baffle 5. When the material contacts the baffle 5, it falls directly along the wall of the baffle 5, passes through the discharge pipe 2 and falls onto the conveyor belt. The operator can adjust the position of the connecting rod 4 according to the height and position of the material accumulation on the belt, place the connecting rod 4 in the slots 3 at different positions, change the position of the baffle 5 in the discharge pipe 2, and adjust the size of the discharge space on both sides of the baffle 5 to prevent the leak from being blocked. At the same time, the landing point of the material can be controlled to prevent the belt from deviating.

[0033] When the material unloading point is not in the middle of the belt, the uneven distribution of force on the belt along the longitudinal centerline due to eccentric loading causes a large difference in force, which can directly cause the belt to deviate during operation. When the belt deviates, conventional technical measures require adjusting the position of the hopper or the belt. However, the hopper device provided by the utility model only requires adjusting the position of the baffle to adjust the material's landing point, so that the material falls in the middle of the belt, preventing serious belt deviation.

[0034] Example 2

[0035] A device for preventing the material from being blocked, such as Figure 4 As shown, the technical solution in this embodiment is basically the same as that in embodiment 1, except that the card slot in this embodiment can slide along the top of the drain 1, making adjustment more convenient.

[0036] A slide rail 6 is fixed to the top of the left and right side walls of the drain 1, and a slider 7 is provided on the slide rail 6. The slider 7 is U-shaped, and the groove in the middle is the card slot. The two ends of the connecting rod 4 are respectively placed in the groove in the middle of the slider 7. When the position of the baffle 5 needs to be adjusted, the slider 7 can be directly slid without lifting the connecting rod 4, which is more convenient and labor-saving.

[0037] The tops of the two opposing side walls of the slider 7 are equipped with stop bolts 701. The slide rail 6 is provided with multiple positioning holes 601 along its length. The tops of the side walls of the drain 1 are provided with multiple fixing holes corresponding to the positioning holes 601. The stop bolts 701 are threadedly connected to the positioning holes 601 and the fixing holes. After adjusting the baffle 5 to the appropriate position, the stop bolts 701 are inserted into the positioning holes 601 and the fixing holes and tightened to prevent the baffle 5 from moving during unloading.

[0038] Example 3

[0039] A device for preventing the material from being blocked, such as Figure 5 and Figure 6 As shown, the technical solution in this embodiment is basically the same as that in Example 1, except that: a stirring device is provided on both sides of the baffle 5 inside the funnel 1 in this embodiment, and a bin wall vibrator 10 is installed on the outside of the front and rear side walls of the funnel 1.

[0040] The stirring device includes an inclined stirring shaft 9 with a plurality of stirring blades 901. A drive motor 8 is mounted on the lower portion of the left side wall of the funnel 1. The output shaft of the drive motor 8 is connected to the stirring shaft 9. The drive motor 8 drives the stirring shaft 9 and the stirring blades 901 to rotate, stirring the material inside the funnel 1, preventing accumulation or bridging of the material inside the funnel 1 and ensuring smooth material discharge. The inclination angle of the stirring shaft 9 can be designed according to the shape of the funnel 1 or actual production needs.

[0041] At the same time, a bin wall vibrator 10 is installed on the outside of the front side wall and the rear side wall of the drain 1 to vibrate the front side wall and the rear side wall, which is conducive to rapid material discharge and enhanced anti-blocking performance.

[0042] Example 4

[0043] A device for preventing material discharge from being blocked. The technical solution in this embodiment is basically the same as that in embodiment 1, except that the connection structure between the baffle 5 and the connecting rod 4 in this embodiment is different.

[0044] The connecting rod 4 is made of steel rod. Figure 7 As shown, a connecting plate 401 is welded to the bottom of the connecting rod 4. A fixing plate 402 is provided on one side of the connecting plate 401. The top of the baffle 5 is located between the connecting plate 401 and the fixing plate 402. The widths of the fixing plate 402 and the connecting plate 401 are the same as the width of the baffle 5. The connecting plate 401 is provided with multiple fastening bolts 403. The upper portion of the baffle 5 and the fixing plate 402 are provided with multiple threaded holes. The fastening bolts 403 pass through the threaded holes on the baffle 5 and the fixing plate 402 and connect with nuts 404. During installation, the left and right edges of the baffle 5 and the fixing plate 402 are aligned with the left and right edges of the connecting plate 401. In this embodiment, the baffle 5 is fixed firmly by the connecting plate 401, the fixing plate 402, and the fastening bolts 403. If the baffle 5 is damaged, it can be replaced by unscrewing the fastening bolts 403.

[0045] The anti-clogging material discharge device provided by the utility model places the baffle inside the discharge pipe by means of a connecting rod. By moving the connecting rod, the position of the baffle can be changed, and the discharge space on both sides of the baffle can be adjusted to prevent the discharge from being blocked, reduce the number of times of manual cleaning of accumulated material in the discharge, and improve production efficiency. At the same time, the material falling point can also be controlled to prevent the belt under the discharge from serious deviation, thereby increasing the belt life of the belt conveyor and reducing the belt maintenance cost.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
