The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

Example one

As shown in fig. 1 to 4, the present embodiment provides a device for detecting chute blockage, which includes a detection hole 111 formed in a side wall of a transfer chute 11, and further includes a detection switch 21, a support assembly and a material receiving assembly which are arranged outside the transfer chute 11, wherein the support assembly is located below the detection hole 111; the material receiving assembly is hinged to the supporting assembly and is configured to be capable of rotating from a first position for closing the detection hole 111 to a second position for triggering the detection switch 21 under the action of the material; the hinge point of the supporting component and the receiving component is located below the detection hole 111 and is located between the gravity center of the receiving component when the receiving component is located at the first position and the gravity center of the receiving component when the receiving component is located at the second position in the horizontal direction.

When the driving wheel 12 drives the belt 13 to rotate, the belt 13 transports the material to the transfer chute 11, and in the process of separating the material from the belt 13, the material splashes or the material is blocked in the transfer chute 11 and cannot continue to move downwards. The detection device for the material blockage of the transfer chute realizes the detection of material splashing and the jam condition of the transfer chute 11 and can trigger the detection switch 21 through the material receiving component hinged on the support component at the lower side of the detection hole 111, due to the existence of inertia, the material is easy to impact the position of the material receiving component close to the lower part of the detection hole 111 after being thrown out by the belt 13, the force arm of the material receiving component is short, the sensitivity of the material receiving component is low, when the material is impacted by ejection with small mass, the material receiving component cannot act, even if the gravity center of the material receiving component is acted, the hinge point cannot be crossed, and the generation of false detection signals is avoided; in addition, because the pin joint is located between the focus when the material receiving component is in the first position of shutoff inspection hole 111 and the focus when the material receiving component is in the second position of triggering detection switch 21, when the material receiving component is in the second position, even if the material receiving component no longer blocks up or the ejection material of great mass leaves the back in the transfer chute 11, because the action of gravity material receiving component can keep in the second position motionless, be convenient for look for the accident reason after driving wheel 12 stalls.

It should be noted that, after the material receiving component triggers the detection switch 21, the driving wheel 12 stops rotating, and the belt 13 stops conveying material, and the reason for the stopping of the driving wheel 12 may also be an electrical reason, and if the material receiving component automatically resets after triggering the detection switch 21, the reason for the stopping of the driving wheel 12 is not easy to be found.

Optionally, the receiving assembly includes a receiving plate 41 and a supporting rod 42, the receiving plate 41 is fixedly connected to one end of the supporting rod 42, the other end of the supporting rod 42 is hinged to the supporting assembly, and the receiving plate 41 can close the detection hole 111 by its own weight when in the first position. Specifically, the support rod 42 extends at an obtuse angle to the receiving plate 41. This arrangement allows the material receiving assembly to be positioned at two gravity center positions of the first position and the second position, respectively, at two sides of the hinge point in the horizontal direction, and the design and manufacturing costs of the support rod 42 are low. In this embodiment, optionally, the material receiving plate 41 and the supporting rod 42 may be welded, but not limited to, to each other.

In this embodiment, furthermore, the receiving plate 41 is provided with a weight portion for adjusting the weight or the center of gravity position of the receiving assembly. This setting makes the weight or the focus of receiving the material subassembly to adjust, and then makes the sensitive degree of reaction after receiving flitch 41 is by the striking to adjust, can control the size that can make the material that splashes that receives flitch 41 to take place the action. The larger the weight of the receiving plate 41 is, the lower the sensitivity of the reaction of the receiving plate 41 is, and the larger the size of the material is required to impact the receiving plate 41 to actuate and trigger the detection switch 21. The larger the horizontal distance between the center of gravity and the hinge point when the receiving assembly is in the first position, the lower the sensitivity of the receiving assembly, and the lower the possibility of false detection.

Regarding the arrangement of the counterweight portion, in the present embodiment, specifically, the counterweight portion includes a hook on which a counterweight is hung. Preferably, a plurality of hooks are uniformly distributed on the material receiving plate 41, and alternatively, the hooks may be arranged in a manner of, but not limited to, a matrix of 4 × 4. This setting makes the weight and the focus position of receiving flitch 41 can adjust through the balancing weight, and is simple and easy to operate. Further, regarding the arrangement of the weight block, in this embodiment, the weight block may be a container with a hook, and the container may be filled with iron powder, sand, water, or the like.

Specifically, the trigger 43 may be, but is not limited to, a steel plate welded to the material receiving plate 41, and one end of the steel plate for triggering the detection switch 21 protrudes out of the material receiving plate 41. This arrangement enables the triggering of the detection switch 21 to be achieved at a lower cost.

In order to improve the stability of the receiving plate 41 in the moving process, in this embodiment, optionally, the supporting assembly includes at least two supporting frames 3 arranged at intervals along the horizontal direction, each supporting frame 3 includes a first rod 31 and a second rod 32 vertically and fixedly connected to one end of the first rod 31, the other end of the first rod 31 is fixedly disposed on the outer side of the transfer chute 11, and the receiving assembly is hinged to the first rod 31. This setting makes supporting component's simple structure, practices thrift the cost. The number of the supporting frames 3 may be, but is not limited to, two. The receiving plate 41 is located between the two support frames 3 and is hinged to the two support frames 3 through the two support rods 42, so that the receiving assembly is more stable in the process of rotating around the hinge point.

Optionally, the first rod 31 is provided with a hinge hole 311, and the receiving assembly is hinged with the first rod 31 through the hinge hole 311. Specifically, the hinge hole 311 of the first rod 31 is a first hinge hole, the other end of the support rod 42 is provided with a second hinge hole, and a pin passes through the first hinge hole and the second hinge hole to complete the hinge connection between the support rod 42 and the first rod 31. Alternatively, the center line of the hinge hole 311 is parallel to the center line of the driving wheel 12.

Optionally in this embodiment, a detection device for transferring chute putty still includes the locating part, and the locating part is used for restricting the angle that receives the material subassembly to rotate around the pin joint. This setting can prevent to receive the material subassembly to be too big around pin joint rotation angle after the transportation chute 11 is blocked up, and the degree that inspection hole 111 was opened is too big, leads to the material to discharge in a large number through inspection hole 111, causes extravagantly and increases the degree of difficulty of cleaning work.

In combination with the structure of the supporting component, in the embodiment, regarding the arrangement of the limiting component, specifically, the limiting component is a limiting plate 5, and the limiting plate 5 is fixedly disposed between the two second rods 32.
