Description

[Detailed description of the invention] [Industrial application field] The present invention has a plurality of rows of funnels formed in parallel at the bottom of a hopper that accommodates fertilizer or seeds, and a feeding roller at the bottom end of each funnel. The present invention relates to an agricultural feed-out device configured to fertilize or sow multiple rows of seeds.

[Conventional technology]

In this type of feeding device, it is necessary to adjust the feeding amount of the feeding rollers arranged for each strip to be equal. When making this adjustment, first, feed the hopper to the full with fertilizer or other powder, then level the entire upper surface of the powder by hand, and then, while performing the feeding operation, each funnel Compare the degree of descent of the upper surface of the powder or granule material corresponding to the upper part of the object, and adjust the feeding amount so that the degree of descent of the upper surface of each is the same, that is, the amount of reduction of the powder or granule material is the same. By doing so, the amount of feed is equalized. The conventional agricultural feeding device has a hopper 10 as shown in Fig. 4A.
In some cases, a plurality of funnel parts 11 are formed in parallel at the bottom of the hopper 10, or as shown in FIG. In this case, the powder and granular material storage chamber is divided into each row, or as shown in FIG.
There was one in which a partition plate 22... was inserted into the middle of... to divide the powder storage chamber into each strip. (References not listed) [Problem that the invention attempts to solve] However, in the case shown in Figure 4 A, the powder and granule storage chamber is not divided into individual rows, and as a result, the powder and granules flow into the adjacent funnel. As a result, there was a problem in that it was not possible to know the exact degree of descent of the upper surface of the powder particles for each strip.

In addition, in the cases shown in Fig. 4 B and C, since the powder storage chamber is divided into each strip, it is possible to know the exact degree of descent of the upper surface of the powder and granules for each strip, but the former In the latter method, the partition wall 21 gets in the way and makes it difficult to level the entire upper surface of the powdery material, and in the latter method, the powdery material acts as resistance, making it difficult to insert the partition plate 22. There was a problem.

Therefore, as a means to eliminate the above-mentioned drawbacks, as shown in Japanese Utility Model Application No. 58-59410, the funnel part of the hopper is deepened, and the powder storage chamber is divided into each row. It is conceivable to make it possible to know the exact degree of descent of the top surface of the powder and to make it easier to level the entire top surface of the powder, but in such a case, the capacity of the entire hopper will decrease and , it had the disadvantage of being weak against external forces in the vertical direction.

The purpose of the present invention is to solve the above-mentioned conventional problems.

[Means for solving problems]

The characteristic structure of the agricultural feeding device according to the present invention, which was taken to achieve the above object, is that the hopper is formed in a shape in which a plurality of funnel portions are connected in series on the bottom side of an outer peripheral wall composed of vertical vertical walls, and The upper end is completely open, and a plate-shaped partition wall that is slightly lower than the upper end of the hopper is vertically erected in the middle of each funnel, and the cross-sectional area of the compartment partitioned by the partition wall is approximately In addition to being identical, the interior of each compartment can be seen through from the outside, and the functions and effects thereof are as follows.

[Effect]

Since a partition wall is erected in the middle of the funnel section to divide the powder storage chamber of the hopper into each row, it is possible to prevent the powder and granules from flowing into the adjacent funnel section. Moreover, the upper end of the hopper is completely open, and the upper end of the partition wall is located lower than the upper end of the hopper, so even though the partition wall is provided, powder and granules can be easily and quickly transferred to each compartment of the hopper. In addition, the partition wall does not get in the way when the powder and granules fully supplied to each compartment are leveled horizontally by hand so that the upper surfaces are at the same height. In addition, since the cross-sectional area of each compartment divided by a partition wall is the same or almost the same, it is possible to determine whether each feeding roller You can see the degree of variation in the amount of feed. Furthermore, since the inside of each compartment can be seen through from the outside, it is possible to easily and quickly determine the degree of descent of the top surface of the powder and granules stored in each compartment without the hassle of opening the lid. .

Furthermore, by providing a partition wall in the middle of each funnel to form a compartment, the capacity can be increased compared to when the funnel is deepened to form a compartment, and external external forces in the vertical direction can be applied. become stronger against

[Effect of idea]

Therefore, it is easy to supply powder and granules such as fertilizer and seeds to the hopper, and the amount of feed can also be easily controlled.Furthermore, the number of times powder and granules are replenished can be reduced, and the overall wall thickness of the hopper can be reduced. It can strongly withstand external forces in the vertical direction, such as body vibration, without increasing the thickness.
