Description

[Detailed description of the invention] [Industrial application field] Preventing root vegetables from spilling out from the notch in the tank of a harvesting machine that uses a conveyor mounted on a tank for harvesting root vegetables when the tank is dumped up. This invention relates to a rubber shutter device designed to do this.

[Conventional technology]

Conventionally, it was made up of only a guide rod, a rubber plate, and a coil spring, so when the conveyor was placed on the conveyor, the rubber plate fell horizontally forward and the lower end attachment part was pulled abnormally, and the coil spring also stretched abnormally, causing the rubber plate to fall. There were drawbacks such as the attachment part and coil spring breaking in a short period of time.

[Problem that the invention attempts to solve]

Let's solve problems such as damage caused by the attachment of the rubber plate being pulled abnormally in the horizontal direction, damage in a short period of time due to the coil spring being pulled abnormally diagonally forward and downward, and problems such as stretching out due to repeated movements. The idea is to

[Means for solving problems]

A notch for placing the conveyor is provided on one side of the tank body, support rods are fixed upright on both sides of the notch, and an arc-shaped sled is attached vertically inside the support rod. A rubber plate with a width equal to the height and a length equal to the width of the notch is formed, the lower end of the rubber plate is fixed to the lower edge of the notch over the entire length, and the upper end of the rubber plate is fixed to the lower end of the notch. The guide rod is installed horizontally, and both ends of the guide rod are inserted into the sled via rollers, and both ends of the guide rod protrude outside the sled.
Both ends of the guide rod are stretched upward from the top with coil springs, so when the conveyor is lowered and placed on the guide rod, the guide rod descends along the sled through the rollers, so the rubber plate can be easily moved. Since the guide rod is folded in half and descends, and the guide rod comes into contact with the support rod at the lower end of the sled and stops, the coil spring will not be abnormally pulled downward, and the lower end attachment part of the rubber plate will not be pulled. Moreover, since the rollers descend along the sled, the movement is smooth, and the above-mentioned problems can be satisfactorily solved.

[Effect]

When using the conveyor, the tank is dumped down, and when the conveyor is lowered, the bottom surface of the conveyor rests on the guide bar, and as it descends further, the guide bar smoothly descends as the rollers roll along the inside of the sled, so that the rollers are Since the sled is curved in an arc toward the inside of the tank, the rubber plate is smoothly folded in half from the middle, and the rollers are guided to the bottom of the sled together with the guide rod.
Since the coil spring stops when it comes into contact with the support rod, no excessive tensile force is applied to the coil spring, and no tensile force is applied to the lower end of the rubber plate, so it can withstand repeated use and can be used without damage.

〔Example〕

A notch 3 for placing a conveyor is provided on one side 2 of the tank body 1, a support rod 4 is fixed upright on both sides of the notch 3, and the inside of the support rod 4 is curved toward the inside of the tank body 1. An arc-shaped sled 5 is attached vertically, and a rubber plate 6 having a width w equal to the height of the sled 5 and a length l equal to the width of the notch 3 is separately formed. The lower end is fixed to the inner side of the lower edge 7 of the notch 3 over the entire length with bolts, nuts, rivets, etc., and the guide rod 8 is attached to the upper end of the rubber plate 6 via the plate 9 with bolts, nuts, rivets, etc. The guide rod 8 is installed horizontally and extends longer on both sides than the rubber plate l, and a roller 11 is fitted to the extension part 10. The guide rod 8 is inserted into the split circular space 12, with both ends of the guide rod 8 protruding outward from the sleds 5 on both sides, and the coil springs 1 are inserted at both ends of the guide rod 8.
3 is latched through a plate 16, and the other end of the coil spring 13 is fixed to the upper end of the support rod 4 on the plate 14, so that the latching rubber plate 6 is always stretched above the plate 14.

Note that 15 indicates a metal fitting for holding down the rubber plate 6.

[Effect of idea]

The roller smoothly descends as it rolls along the inside of the sled, the rubber plate is smoothly folded in half from the middle along the sled, and the guide rod stops when it comes into contact with the support rod, so there is no undue tension on the coil spring. Since no force is applied and no tensile force is applied to the lower end of the rubber plate, it can withstand repeated use and can be used without damage.
