Description

[Detailed description of the invention] The present invention relates to improvements in grain feeding equipment for grain silos.

In a general vertical grain silo, if grain is supplied directly from the upper supply port or by flowing down through a fitting flow grain tube of any length, especially for beans with soft skin,
The grain surface is lacerated by the impact force when flowing down, resulting in a large number of damaged grains and deterioration of quality.In addition, the grains in the silo accumulate in a mountain shape around the falling point, causing a large amount of damage on the surrounding surface. However, the storage capacity was reduced due to the formation of large voids.

In order to eliminate the above-mentioned drawbacks, the present invention provides a spiral downward supply gutter in the vertical direction along the peripheral wall surface of the grain silo,
By connecting the upper end of the supply gutter to the grain supply port of the silo, the grains slide at a low speed within the feed gutter and overflow from the end of the gutter body, causing the grains to be absorbed by the impact force mentioned above. Safely transports grain inside the silo without causing surface lacerations.
The grains are fed smoothly, and the position where the grains overflow from the gutter body moves along the peripheral wall surface over time, and the grains are circulated around the entire circumference to accumulate the grains evenly throughout the inside of the silo. In this way, the grain silo's grain feeding function is facilitated, its storage capacity is increased as much as possible, and good quality grain without damaged grains is always ensured and stored at a high efficiency. The aim is to develop and provide a device to do this.

The present invention will be explained with reference to embodiment figures. FIG. 1 shows a vertical cylindrical grain silo 1, in which an elevator 2 is erected on one side of the shell port 1, and the two discharge ports 3 and the grain supply port 4 of the silo 1 are connected to a grain pipe 5. and grain silo 1
A spiral downward supply gutter 7 is provided in the vertical direction along the inner peripheral wall surface 6, and the upper end 8 of the feed gutter 7 is connected to the grain supply port 4 of the silo 1, and 9 is connected to the bottom of the silo 1. This is a discharge port installed in the FIG. 2 is a partially enlarged perspective view of the supply gutter 7, in which the flexible part of the gutter body having a cross section is fixed by adhesive bonding to the surrounding wall surface, and the cross section of the supply gutter 7 is U-shaped. 10 is a supply hopper at the bottom of the elevator.

Since the configuration is as described above, the supply hopper 1 at the bottom of the elevator 2
When the machine 2 is rotated, the beans are fried by the elevator 2 and sent from the discharge port through the grain flow pipe 5 to the grain supply port of the silo 1. 4
81. : At the same time, it flows down the spiral supply gutter 7 at a low speed and overflows from the lower end of the gutter body,
Furthermore, the position of the beans overflowing from the gutter body moves over time along the peripheral wall surface 6 due to the continuation of the feeding action, circulates around the entire circumference, and accumulates uniformly throughout the inside of the silo.
The grains can flow safely and smoothly into the silo without causing intra-grain lacerations due to the impact mentioned above, improving grain feeding efficiency, and evenly accumulating them throughout the silo for storage. It has the effect of increasing the capacity of the trowel as much as possible, ensuring high-quality grain without damaged grains, and efficiently storing it.

Fig. 3 shows a grain silo O1A equipped with an alternating ventilation drying section, and inside the silo 1A, an outer wall 111 and an inner wall 1112, which are made of a cylinder with a porous wall, are installed concentrically at appropriate intervals. At the same time, the ventilation chamber 13 provided on the outside and the ventilation chamber 14 provided on the inside are respectively connected to the ventilation device 16 via the switching valve part 15, and the peripheral wall surface 6A on the outside of the inner cylinder 12
A spiral downward supply gutter 7A is provided, and the upper end 8A of the supply shaft 7 is connected to the grain supply port 4A of the silo 1A, 17 is a ventilation control valve provided in the inner cylinder, and 18 is a ring cylinder. It is a grain room of the shape.

Therefore, the raw material grain for the beans and grains fried by the elevator 2 flows into the grain supply port 4A of the grain silo 1A through the grain flow pipe 5. The upper end 8A1 of the downstream supply gutter 7A provided on the peripheral wall surface 6A. : As the grains flow down, they flow slowly through the spiral supply gutter 7 and spill out from the lower end of the gutter body, and the position where the beans overflow from the gutter body becomes closer to the surrounding wall surface over time due to the continuation of the feeding action. 6A, circulates around the entire circumference, and accumulates uniformly throughout the inside of the silo, so that grains can move inside the silo safely and as in the case of the downstream feed gutter of grain silo 1. It can flow down smoothly to prevent grain tearing, improve the feeding efficiency, accumulate grain evenly throughout the inside of the silo, and increase the storage capacity as much as possible. The cylindrical wall 5- is reinforced by the supply gutter, which has the effect of making its structure stronger.
