BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lateral feed chain conveyor for carrying brown rice and the like while preventing brown rice cracks from forming on the bottom plate of the machine casing.

[0002]

2. Description of the Related Art In a conventional transverse feed chain conveyor of this type, a conveyor chain having right and left blades on both sides of a chain body or a direction perpendicular to the direction of rotation, or an elastic blade plate extending over the right and left blades on both sides. Use the attached transport chain.

Then, the brown rice or the like is sequentially pushed by the right and left blades on both sides or the elastic blades attached to the right and left blades on both sides along the bottom plate of the machine casing to carry the brown rice and the like.

[0004]

[Problems to be Solved by the Invention] Brown rice has the property that fat, phosphorus, potassium, starch and the like in the bran layer adhere to the metal surface where friction is weak under the influence of temperature and moisture. The sticky thing is called brown rice red.

In this type of conventional lateral feed chain conveyor, brown rice or the like is conveyed, and blades on both sides of the chain are used, or
The elastic blades attached to the right and left blades on both sides only push in sequence in the direction of rotation of the conveyor chain along the bottom plate of the machine casing, so if the number of conveyances is repeated, the brown rice stains that stick to the bottom plate of the machine casing The accumulated height increases, and the accumulated height of the brown rice scale becomes 3 to 4 mm. for that reason,

(1) The load on the transport chain increases because it adversely affects the smooth sliding running action of the transport chain on the bottom plate of the machine casing.

(2) There is a risk of damaging the blades of the conveyor chain.

(3) Brown rice or the like remains in the machine casing.

(4) There is a problem in that the carrying capacity is lowered.

Currently, as a solution to the above problems,

(1) Periodically, the conveyor chain is removed, and the brown rice stains inside the machine casing are removed with a spatula or the like to clean the inside of the machine casing.

(2) In order to prevent the occurrence of brown rice cracks, means such as attaching a heater to the back surface of the bottom plate of the machine casing is used.

[0013]

[Means for Solving the Problems] The present invention prevents the brown rice cracks from forming on the bottom plate of the machine casing, and transfers the brown rice etc. smoothly and reliably from the beginning without the residue of the brown rice etc., to improve the work efficiency. In order to do so, the drive sprocket (4) is erected by the drive shaft (2) at the other end of the oblong machine casing (1), and is freely rotatable by the driven shaft (3) at one end of the machine casing (1). The chain main body (6) of the conveyor chain (a) is hung on the driven sprocket (5) installed on the bridge, and the chain main body (6) is provided on both side links (7) at appropriate intervals.
An inclined blade (8) inclined outward in the direction of rotation to the outside of the
Right-angled blades (10), which are perpendicular to the rotation direction, are provided on the outer sides of the other both-side links (9), respectively, and extend over both side inclined blades (8) outward and both sides from the both side inclined blades (8) to form a substantially machine casing. An elastic scraping plate (11) having an inner width of (1) is attached, and the right and left blades (10) are spread over the both right and left blades (10) at appropriate intervals and are projected substantially outwardly and outwardly from the right and left blades (10). An elastic blade plate (12) having an inner width of 1) is attached, and the elastic scraping plate (11) and the elastic blade plate (12) are arranged in contact with each other on the bottom plate (13) of the machine casing (1) to laterally feed a chain conveyor. The purpose is to prevent brown rice cracks from forming on the bottom plate of the machine casing, and to carry brown rice etc. smoothly and reliably from the beginning without increasing the residue of brown rice etc. to improve the work efficiency. Sloped blades on both sides, Provided the corner blades respectively, the both side inclined cotton connexion elastic scraping the blade plate, and realized by mounting places of cotton in the sides perpendicular blade the connexion elastic slats, respectively.

Further, an elastic blade plate (12) having an almost inner width of the machine casing (1) slides in contact with the bottom plate (13) of the machine casing (1),
The brown rice transfer operation is performed reliably to prevent the brown rice from remaining in the machine casing (1).

The same operation as described above is carried out when another grain or the like is transferred instead of the brown rice.

[0027]

The horizontal feed chain conveyor of the present invention has the following advantages.

(1) The chain main body of the transport chain is provided with inclined blades on both sides which incline outward in the direction of rotation at appropriate intervals, and protrudes outwardly and on both sides of the inclined blades on both sides of the chain. Since the elastic scraping plate of the inner width of the housing is attached, the slanting elastic scraping plate is pressed against the bottom plate of the machine housing by the lifting force of the transport chain due to the downward load pressure due to the pushing of the transported object during the transportation work. As a result, it is possible to prevent brown rice cracks from forming on the bottom plate of the machine casing, and to carry out the carrying operation smoothly from beginning to end.

(2) Since the elastic blades of approximately the inner width of the machine casing are attached to both right-angled blades at appropriate places on the chain main body of the transport chain, projecting outward and on both sides of the right-angled blades. The plate surely carries the carrying work and prevents the carried object from remaining in the machine casing.
Therefore,

(B) There is no need for cleaning after the work.

(B) There is no possibility of causing harmful insects due to the residue of the conveyed product in the machine casing, which is beneficial for hygiene.

(3) Since the inclined blades on both sides with elastic scraping plates and the blades on both sides with elastic blades on the conveyor chain are provided at appropriate intervals in the main body of the conveyor chain, the conveyor chain rotates smoothly and smoothly. Therefore, the transfer work can be performed well.

(4) Since only the outer edges and both side edges of the elastic scraping plate and the elastic blade plate contact and slide on the inner surface of the machine casing, no noise is generated and the work can be performed quietly.

(5) The structure is simple and can be easily manufactured at low cost.
