[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt conveyor scraper which can be easily attached and detached.

[0002]

2. Description of the Related Art When a substance is transported on a belt conveyor when the substance is transported on a belt conveyor, a flat scraper 30 as shown in FIG.
It is common practice to scrape off the material that has adhered to the belt conveyor 31 by using the above method. In addition, there is an example in which a piano wire is stretched on a belt surface to form a scraper.

[0003]

While the scraper is being used, the scraped one adheres to the scraper and needs to be cleaned or replaced. Particularly in the field of foods and the like, there is a problem of contamination by various bacteria, and cleaning and sterilization are essential requirements. However, in the above-mentioned conventional scraper, it is fixed with a screw or the like, and its attachment and detachment is troublesome. It must be, and the tendency is remarkable.

In view of this situation, the inventor of the present application has made intensive studies and as a result, formed a scraper with a wire, installed a rotatable support member at one end, engaged with the scraper, and engaged with a scraper from the other end. The inventor of the present invention has found out that it is easy to attach and detach it if it is stretched with a suitable tension member.

That is, the present invention is directed to a cylindrical spring holding member which is provided with a ring member at both ends and is formed of a wire, and a pin is provided at one end and a pin is provided at the other end thereof so as to be rotatable about the pin. An engagement member having a hook at one end and a bolt at the other end inserted into the spring holding member from the insertion opening, and being fitted at one end of the engagement member and regulated by the bolt and the insertion opening stepped portion. A support member for a scraper formed by a mounted spring, a frame having an insertion port, a shaft inserted through the insertion port, and having a hook-shaped engagement member at a distal end portion, and rotatable about the frame and the shaft. A tension member of a scraper formed by a link mechanism pin-connected to the scraper, connecting the scraper to the support member and the tension member, and connecting the scraper to the belt conveyor via a spring of the support member by the tension member. A scraper which is characterized by being configured so as to adhere stretched.

[0006]

In FIG. 1, reference numeral 1 denotes a belt conveyor, 2 denotes a scraper formed of a wire or a rod, and ring members 3 are provided at both ends. Reference numeral 4 denotes a support member of the scraper 2, and reference numeral 5 denotes a tension member of the scraper 2. Details 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 spring holding member, one end of which is rotatably supported by a pin 7, and the other end of which has an opening 8 through which an engaging member of the scraper 2 described later is inserted. I have. The pin 7 is provided at a position substantially along the axis of the conveyor 1 so that the scraper 2 comes into close contact with the belt conveyor 1.

Reference numeral 9 denotes a bar-shaped engaging member, one end of which is formed in a hook shape. It is preferable that the engaging member 9 is made of a square material because rotation of itself can be prevented. Engaging member 9
The spring 10 is fixed to the other end of the spring holding member 6 by the bolt 11 screwed to the engagement member 9 and the insertion step 8A. When the 9 moves forward and backward, it acts as a cushion.

Next, the tension member 5 of the scraper 2 will be described with reference to FIGS. 3 and 4. First, it is preferable that the tension member 5 uses a clamp. Reference numeral 15 denotes a shaft, which is attached to an insertion port 17 provided in a frame 16 so as to be able to advance and retreat, and a hook-shaped engaging member 18 for engaging with the scraper 2 is coaxially protruded at a tip end thereof. Has been established.

Reference numeral 19 denotes a link mechanism comprising 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 is a right angle of the handle 20. And also rotatably pinned. On the other hand, the tip of the handle 20 is pinned to the shaft 15 in the same manner as described above.
The shaft 15 reciprocates according to the rotation of.
When the handle 20 is at the position A, the scraper 2 is loosened and the position where the scraper 2 is attached and detached, and when the handle 20 is at the position where the scraper 2 is stretched, the spring 10 is in the most compressed state.

[0011]

The present invention is constructed 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 engagement member 9 of the support member 4 are combined. Next, the ring member 3 and the engaging member 18 of the tension member 5 are similarly combined. At this point, the scraper 2 is still loose.

Then, by operating the handle 20, B
, The scraper 2 is pulled, tightly attached to the conveyor belt 1, and scraped off from the belt.

FIG. 5 shows another embodiment of the supporting member, in which the whole supporting member 4 is formed by a spring 10 and one end thereof is rotatably supported.
This is an example in which the other end is formed in a hook shape.

[0014]

[Effect of the invention] Despite the simple structure of the present invention,
The attachment and detachment of the scraper can be performed safely and quickly.

[0015]
