Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to picking up spilled material in a vibrating and conveying device having a sieving function by selecting and sieving a material while conveying it using an elastic sieving net. It relates to a collecting device.

[Conventional technology]

FIGS. 3 to 6 show a conventional vibrating transfer device having a sieving function.

Sieve mesh mounting frames F ₁ and F ₂ are arranged between the upper trough T ₁ and the lower trough T ₂ which vibrate integrally, along a direction perpendicular to the material conveying direction P. Since the sieve screen mounting frames F ₁ and F ₂ are arranged alternately, they are in front of each other, and a predetermined space is provided between the frames F ₁ and F ₂ .

The screen attachment frame F ₁ is attached to the angle member 1, and the angle member 1 has a structure in which the vibration applied to the upper and lower troughs T ₁ and T ₂ is transmitted via the elastic body 2. . On the other hand, the sieve screen mounting frame F ₂ is
Attached to T ₁ and the lower trough T ₂ and connecting plate 3 which are connected to, has a structure in which vibration applied to the top and bottom of the trough T _1, T ₂ is directly transmitted to the sieve screen mounting frame F _2.

Since the vibration transmitted to the angle member 1 is amplified by the action of the elastic body 2, the amplitude of the screen mesh mounting frame F _{1 in} the horizontal direction (the same direction as the material conveying direction P) is the screen mesh mounting frame F ₂ Greater than that.

Inside the side plates 4 of the upper trough T ₁ are contact plates 5 respectively.
Is attached, and the lower end portion of the contact plate 5 enters the opening of the lower trough T ₂ .

The elastic sieve mesh 6 is an elastic plate such as a rubber plate having a large number of meshes 6a perforated therein and has elasticity. The front and rear ends of the elastic sieve mesh 6 are attached to the sieve mesh attachment frames F ₁ and F ₂ as shown in FIG. 6, and both end faces of the elastic sieve mesh 6 slidably contact the contact plate 5. doing. Therefore, the elastic sieve mesh 6 functions as the bottom plate of the upper trough T ₁ .

As described above, since the screen mesh mounting frames F ₁ and F ₂ have different horizontal amplitudes, and both end surfaces of the elastic screen mesh 6 slidably contact the contact plate 5, The elastic sieve mesh 6 repeatedly expands and contracts in the front-rear direction during the vibration conveyance. Due to the expansion and contraction of the elastic sieve mesh 6, the mesh 6a
Prevents material from clogging.

When the elastic sieving net 6 is repeatedly expanded and contracted along the front-rear direction during vibration conveyance, both end faces of the elastic sieving net 6 are brought into contact with the plate surface of the contact plate 5, as indicated by a two-dot chain line in FIG. As the elastic sieving net 6 vibrates up and down as it slides along, the seals at both end portions of the elastic sieving net 6 may be momentarily broken.

Therefore, due to the vertical vibration of the elastic sieve net 6, a gap is instantaneously created between the both end surfaces of the elastic sieve net 6 and the contact plate 5, and the material M ′ spilled from the gap enters the lower trough T ₂ to form the mesh 6a. There is a problem that the purity of the sorting material Ma contained in the lower trough T ₂ is lowered by being mixed with the sorting material Ma which has passed through the bottom trough T _{2 and} has been sieved off.

[Problems to be solved by the invention]

The present invention is a vibrating and conveying device that conveys materials while screening them using an elastic screen, by collecting the material that spills from the gap generated between the contact plate and the elastic screen during vibration conveyance. , Screened from the elastic sieve screen to prevent mixing with the sorting material contained in the lower trough,
Thus, it is an object to maintain the purity of the sorting material accommodated in the lower trough.

[Means for solving the problem]

Means adopted by the present invention in order to solve the above-mentioned problems,
The collecting trough for collecting the material spilled from the gap formed between the contact plate and the both end faces of the elastic screen during vibration conveyance is disposed directly below the contact plate.

〔Example〕

FIG. 1 and FIG. 2 show an embodiment of the present invention, in which the same parts as those described in the above-mentioned “Prior Art” are given the same reference numerals to avoid redundant description. Only characteristic parts of the present invention will be described.

The lower end portions of the contact plates 5 attached to the insides of the both side plates 4 of the upper trough T ₁ enter the openings of the lower trough T ₂ .

The collecting troughs T ₃ are horizontally arranged immediately below the respective contact plates 5, and the lower end portions of the contact plates 5 enter the inside of the collecting troughs T ₃ . Each picking collecting trough T ₃ is attached to the connecting plate 3 which connects the upper and lower troughs T _1, T _2, is adapted to vibrate a vertical trough T _1, T ₂ and integrally.

When the elastic sieve mesh 6 vibrates up and down during vibration conveyance, the seal between the contact plate 5 and both end surfaces of the elastic sieve mesh 6 is broken, and a gap is instantaneously created between the two, and the upper trough The material M contained in T ₁ spills from this moment. However, since the collection trough T ₃ is disposed immediately below each contact plate 5, the material M ′ spilled from the above-mentioned gap falls along the contact plate 5 as it is, and the collection trough T ₃ is dropped.
It is housed in the T _3.

Therefore, it passes through the mesh 6a of the elastic sieve mesh 6 and passes through the lower trough T ₂
It is not mixed with the screening material Ma which has been sieved off, and the purity of the screening material Ma is maintained.

The material M ′ contained in the collection trough T ₃ spills from the gap formed between the elastic screen 6 and the contact plate 5 and is vibrated and conveyed. Therefore, the material M ′ is collected and again collected in the upper trough T ₁ . Sieve selection may be performed while supplying and vibrating and conveying.

〔The invention's effect〕

According to the present invention, the collection trough is arranged immediately below the contact plate, and the material spilled from the gap generated between the contact plate and the elastic sieve mesh is arranged to be collected in the collection trough.
The material spilled from the gap formed between the contact plate and the elastic sieve mesh does not pass through the mesh of the elastic sieve mesh and mix with the sorting material contained in the lower trough.

Therefore, the purity of the sorting material contained in the lower trough can be maintained.

Further, according to the present invention, since the collecting trough is arranged directly below the contact plates mounted on both sides of the upper trough, the collecting trough can be easily mounted not only on the new vibration transfer device but also on the existing device. And can be implemented at low cost.
