した可動シュートに関する。[Detailed Description of the Invention] When pouring concrete milk into a mold for forming an object such as a concrete pipe, the present invention is capable of moving the charging chute up and down according to the size of the mold. This invention relates to a movable chute that does not swing even when the chute is extended.

なく、規定量の投入物が入らぬために製品が不良品とな
るおそれがある。In general, the materials used as the input materials listed above are:
Since the distance between the chute opening and the input material is fixed,
It is good if the input material is large or the entrance part is large, but
If the input material is small or the closing part is small, not only will a portion of the input material be scattered and wasted during charging, but the product may be defective because the specified amount of input material cannot be inserted. There is a risk that

く形成しておく必要がある。In order to eliminate such drawbacks, conventionally known telescopic chutes, such as Japanese Patent Publication No. 47-4021 and Japanese Patent Application Laid-open No. 54-
Although it is also possible to use what is shown in the 9355th publication,
Concrete milk is made up of gravel, sand, cement, and water and has a considerable weight, and due to its fluidity, the outlet side of the chute (chute opening) must be made considerably narrower than the hopper side.

ッパーからシュートに落下した場合、コンクリートミル
クは前後方向に長く延びたシュ−トの内側面に衝当する
。When concrete milk falls from the hopper into the chute under these conditions, it hits the inner surface of the chute, which extends in the front and back direction.
この衝当は断続的で且つ各部分に不均等にぶつかるため
、この衝激によりシュートは上下方向とくに水平方向に
大きく揺動し、シュート口が所定位置からかづれてしま
う虜れがある。Since this impact is intermittent and hits each part unevenly, this impact causes the chute to swing significantly in the vertical direction, especially in the horizontal direction, and the chute opening may be stuck in a predetermined position.
特にシュートを長く伸ばした場合には上記現象は顕著に
あらわれる。The above phenomenon is particularly noticeable when the shoots are extended long.

ることもない。When the chute openings 21, 22 are moved up and down as described above, the chute openings 21, 22 are smoothly guided by the vertical movement guide mechanism 25, and there is little shaking. The chute openings 21 and 22 are connected to the mold 2.
When the spacing between 9 and 30 is appropriate, move hoppers 2 and 3.
When the input material (for example, mixed concrete, etc.) is dropped from the hopper mouths 2' and 3' by the appropriate amount injection mechanism 36, it is guided by the rubber plates 19 and 2 rivers to the chute openings 21 and 22.
The material is placed into the molds 29 and 30 more accurately. In the movable chute according to the present invention, as described above, the rollers 4, 5, 6, 7 are mounted on the pedestal 1 provided below the hoppers 2, 3 so as to surround the hoppers 2, 3 from at least two directions. A plurality of rolled rubber plates 19, 20 are hung down, and chute openings 21, 22 are attached to the lower ends thereof, so that by moving the chute openings 21, 22 up and down according to the size of the input material (mold) The distance between the chute openings 21, 22 and the molds 29, 30 can be maintained appropriately, and the thrown materials are not scattered and no waste occurs.
従って金型内には投入物が常に設定量投入されるので、
不良品の出るおそれもない。Therefore, the set amount of material is always put into the mold, so
There is no risk of producing defective products.
