Abstract

PURPOSE:To obtain a grain tank to store grains surely, efficiently and temporarily by equipping the bottom of the grain tank with a discharging spiral and a grain sending plate laid in a steep attitude. CONSTITUTION:A discharging spiral 2 is laid along approximately the whole length of a grain tank at a corner part of a bottom wall (e) of the grain tank 1 and a side wall (a) and the bottom wall (e) of the tank 1 are equipped with a plate 3a and a grain sending plate 3 having one end foldable by a hinge 5 and the other positioned in the vicinity of the discharging spiral 2 to give the objective grain tank. The grain sending plate 3 is pressed with increase of piled weight of grain in the tank and made into a steep attitude when the amount of grain stored is reduced so that remaining grain is surely sent to the discharging spiral 2 and position of the center of gravity of the tank itself is lowered and the tank is stabilized.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a grain tank for temporarily storing grain. [Prior Art] Grain tanks have been widely known that can temporarily store harvested grains and, if necessary, discharge the grains using a discharge spiral provided at the bottom.

As shown in Fig. 5, this grain tank 1 was a box-shaped grain tank 1 whose bottom was formed into a funnel shape, and a discharge spiral 2 was provided at the lower end of the funnel. [Problem a to be solved by the invention] In the prior art, since the bottom of the grain tank l is formed in a funnel shape, there is a space between the box-shaped grain tank l and the outer shell where grains cannot be stored. Part S was formed. Therefore, the grain storage capacity decreases by the volume of this space S. Further, when storing grains, the center of gravity of the v1 grain tank 1 became high and unstable.

[Means to solve the problem]

This invention provides the following technical means to solve the above-mentioned problems. That is, a grain tank 1 formed in a box shape, a discharge spiral 2 disposed at the bottom of the grain tank 1, and a grain sink plate 3 biased toward the discharge spiral 2 into a steeply inclined position as much as possible. This is a grain tank characterized by the fact that it is provided with a grain tank.

[Operation and effect of the invention]

When no grain is stored in the grain tank 1, the grain sink plate 3 is held in a steeply inclined position by the biasing force toward the discharge spiral 2 as shown in the imaginary line shown in FIG. When grains begin to be introduced from above the grain tank 1, the grain sink plate 3 is pressed by the increased weight of the grains, and gradually moves against the biasing force to the position indicated by the solid line in FIG. Move to.

At the position shown by the solid line in FIG. 1, the grain flow plate 3 is in a state along the bottom of the planar grain tank l. For this reason, grains are accommodated to every corner of the bottom of the grain tank 1, eliminating the conventional space S and increasing the grain storage capacity. In addition, the center of gravity of the grain tank becomes lower and stable.

As the grains are discharged from the grain tank 1 by the discharge spiral, the pressing force due to the weight of the grains applied to the grain sink plate 3 decreases. Therefore, the grain sink plate 3 gradually returns to its original steeply inclined position due to the biasing force. The lower end of the grain flusher 3 faces the discharge #1 turn 2. Therefore, even if the stored amount of -a grains decreases, the general grain sink plate 3 assumes a steeply inclined position, so that the remaining grains can be reliably guided to the discharge spiral. Note that the steeply tilted posture described here is preferably one that is steeper than the angle of repose of the grain.

〔Example〕

A practical example of this invention will be described in detail below.

The grain tank has side walls a-b-c-d on four sides and a bottom u. It is formed into a rectangular box shape when viewed from the front and from the side at e.

The discharge spiral 2 is located at one corner of the bottom of the grain tank 1. This discharge spiral 2 is constructed over approximately the entire length of the grain tank 1, and is configured such that a conveying device 4 can be connected to it from outside the grain tank 1.

A grain sink plate 3 is provided inside the grain tank.

This grain sink plate 3 consists of two plates 3a and 3b that span the entire length of the inside of the grain tank l. One end of the plate 3a is pivoted to the bottom wall e near the discharge spiral 2, and one end of the plate 3b is bent at the other end by a hinge 5.
The other end is always connected to the side wall a of the grain tank l by a leaf spring 6.
Make it in contact with. Further, the plate body 3a is configured to have a width such that when the plate body 3a is rotated to a state where it contacts the bottom wall e, the other end thereof is located at the corner formed by the side wall a and the bottom wall e. Then, the hinge 5 and the upper part of side ab are connected by a tension spring 7. This tension spring 7 biases the grain sink plate 3 to a steep angle of inclination.

Figure 3 shows a separate grain tank. This grain tank 1 is also provided with a discharge spiral 2 at one corner of the bottom. Then, by operating the lever 8, the entire grain tank 1 is tilted via the arm 9. This allows the discharge spiral 2
The side opposite to where is located will be higher. By performing this operation when there are few stored grains, the grains can be reduced to bottom 4? It can be completely ejected by sliding it along e and taking over to ejection spiral 2. Incidentally, this grain tank L can be mounted on a receiving vehicle T or the like and used as a moving container.
