Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a scraper for a belt conveyor that can be easily attached and detached.

[0002]

[Prior art]

 If the material to be conveyed adheres to the surface of the belt conveyor when the powdery substance is conveyed on the belt conveyor, scrape off the matter adhered to the belt conveyor 31 with a flat scraper 30 as shown in FIG. Is commonly done. In addition to this, there is also an example in which a piano wire is stretched over the belt surface to form a scraper.

[0003]

[Problems to be solved by the device]

 While the scraper is in use, the scraped material adheres to it and must be cleaned or replaced. Especially in the field of food, etc., there is a problem of contamination by various bacteria, and cleaning and sterilization are essential requirements. However, in the conventional scraper described above, it is fixed with screws, etc., and it is troublesome to attach and detach it.In particular, in the case of a scraper formed of wire material such as a piano wire, the bell and the surface should be tightly attached. It must be done and the tendency is remarkable.

In view of the current situation, as a result of earnest research, the inventor of the present application forms a scraper with a wire, installs a support member rotatably formed at one end, engages with the scraper, and clamps from the other end. The inventors have completed the present invention, knowing that if such a tension member is stretched, it can be easily attached and detached.

That is, the invention of the present application is directed to a scraper having wire members provided with ring members at both ends, a scraper support member rotatably provided with a spring and an engaging member, and a scraper having an engaging member at its tip. The scraper is characterized in that the scraper is connected to the support member and the tension member, and the scraper is tightly attached to the belt conveyor through the spring of the support member by the tension member.

[0006]

[Specific means for solving the problem]

 In FIG. 1, 1 is a belt conveyor, 2 is a scraper made of wire rods or rods, and ring members 3 are provided at both ends. Further, 4 is a supporting member of the scraper 2 and 5 is a tension member of the scraper 2, the details of which are shown in FIGS. 2 and 3, respectively.

First, the support member 4 of the scraper 2 will be described with reference to FIG. Reference numeral 6 denotes a pipe-shaped holding member, one end of which is rotatably supported by a pin 7, and the other end of which is provided with an insertion port 8 for inserting an engaging member of the scraper 2 described later. There is. The pin 7 is provided at a position substantially along the axis of the conveyor 1 so that the scraper 2 is in close contact with the belt conveyor 1.

Reference numeral 9 is an engaging member having a rod shape, and one end of which is formed in a hook shape, and is attached to the insertion opening 8 of the spring holding member 6 so as to be able to move back and forth. It is preferable that the engaging member 9 is a square member because it can prevent itself from rotating. At the other end of the engaging member 9, that is, the extending portion into the spring holding member 6, the spring 10 is attached by being restricted by the bolt 11 screwed to the engaging member 9. When 9 moves forward and backward, it acts as a cushion. Reference numeral 12 is a pin-shaped stopper, which acts to hold the support member 4 there.

Next, referring to FIGS. 3 and 4, the tension member 5 of the scraper 2 will be described. First, it is preferable that the tension member 5 uses a clamp. Reference numeral 15 is a shaft, which is attached to an insertion opening 17 provided in the frame 16 so as to be able to move back and forth, and a hook-shaped engaging member 18 for engaging with the scraper 2 is coaxially projected at a tip end thereof. It is set up.

Reference numeral 19 denotes a link mechanism including an L-shaped handle 20 and a belt-shaped link member 21. One end of the link member 21 is rotatably pinned to the frame 16 and the other end thereof is a handle 20. The right-angled part is also rotatably pinned. On the other hand, the tip of the handle 20 is pinned to the shaft 15 as described above, and the shaft 15 reciprocates as the handle 20 rotates. When the handle 20 is A, the scraper 2 is at a position where the scraper 2 is loosened and attached and detached, and when B is at a position where the scraper 2 is stretched, the spring 10 is in the most compressed state.

[0011]

[Action]

 The present invention is configured as described above. First, the position of the handle 20 of the tension member 5 is set to A, and the ring member 3 of the scraper 2 and the engaging member 9 of the support member 4 are combined. Next, similarly, the ring member 3 and the engaging member 18 of the tension member 5 are combined. At this point, the scraper 2 is still loose.

Then, this time, the handle 20 is operated to move it to the position B, the scraper 2 is pulled, the conveyor belt 1 is tightly stretched, and the thing adhered to the belt is scraped off.

FIG. 5 shows another embodiment of the supporting member, in which the entire supporting member 4 is formed of a spring 10, one end of which is rotatably supported and the other end of which is formed into a hook shape.

[0014]

[Effect of the device]

 Despite the simple structure of the present invention, the scraper can be attached and removed safely and quickly.
