Description

  The present invention relates to a crop excavator having a sowing function.

  There is cover crop cultivation in which another plant is planted when the crop is not cultivated and the topsoil is covered with the plant to prevent soil runoff. The sowing time is generally from mid-April to mid-June, taking into account the effect of preventing soil runoff during the rainy season and securing the amount of cover crop grass.

  By the way, when the crop is a spring potato, the harvest time and the sowing time of the cover crop overlap, making it difficult to carry out the cover crop cultivation, which is the reason why the cover crop cultivation is not widespread compared to other crops. In the present invention, a sowing function is added to a crop excavator as disclosed in Patent Document 1 so that crops such as potato can be dug and cover crops can be sowed simultaneously.

JP 2004-254582 A

  The problem to be solved by the present invention is to solve these conventional problems and to enable excavation of crops such as potatoes and sowing of cover crops at the same time.

The configuration of the present invention that solves this problem is as follows.
1) A clay sieve conveyor with a ridge at the front end is attached to the traveling machine forward, and the culvert is dug into the clay to dig out the crops in the soil, and the sieving is removed by the sieve sieve. In the crop excavator that picks up the seeds, a hopper for storing seeds or fertilizer is provided in the traveling machine body, and a discharge port of the hopper is provided so that the seeds or fertilizer is discharged on the soil raised at the tip of the soil sieve conveyor, The crop digging machine characterized in that the discharged seed or fertilizer is mixed with the soil and dropped into the dredged soil. 2) The discharge port of the hopper is placed 20 to 20 along the clay sieve conveyor from the tip of the dredger. The crop excavator as described in 1) above, which is disposed at a position 40 cm behind 3) A diffusion plate for diffusing seeds or fertilizer in the width direction of the dredged material at the discharge port of the hopper is provided. Agricultural crop excavator 4) The crop excavator 5) according to any one of 1) to 3) above, which is provided with a delivery device that feeds seeds or fertilizer in the hopper in conjunction with a conveyor. 1) The seed is a seed for cover crop cultivation. 4) It is in any crop excavator.

  In the present invention, when seeds or fertilizer is introduced into the hopper, the paddle is embedded in the dredged soil, and the traveling machine body is run, a part of the dredged soil is raised in the soil while raising a part of the dredged soil. Agricultural crops are dug up. The excavated crops are picked up by a sieve sieve conveyor, and the attached soil is shaken off by the sieve sieve conveyor. In parallel with the excavation, the seeds or fertilizer in the hopper are discharged onto the raised soil, and the seeds or fertilizer and the soil fall onto the dredged soil while being mixed by the soil sieve conveyor.

  As described above, since the excavation and sowing of the crop can be performed at the same time and the conventional sowing work is saved, it is easy to carry out the cover crop cultivation even when the harvest time of the crop and the sowing time of the cover crop overlap. .

It is explanatory drawing of the crop digger of an Example. It is a partially notched explanatory drawing of the hopper and delivery machine of an Example. It is explanatory drawing which shows digging and sowing of the agricultural products of an Example. It is explanatory drawing of the diffusion plate of the other example of an Example.

  As for the discharge outlet of the hopper of this invention, it is desirable to arrange | position in the position of 20-40 cm back along the soil sieve conveyor from the front-end | tip of a ridge. If it is ahead of 20cm, the seeds or fertilizer will come to the sides of the soil when it rises, and there is a problem that it cannot be sown uniformly on the entire dredged soil. If it is behind 40cm, the raised soil will fall first. However, after that, seeds or fertilizer falls on the surface of the dredged soil and does not mix well with the soil, and there is a problem that the soil covering effect is lost. In addition, when a diffusion plate is provided below the discharge port, the discharged seeds or fertilizer diffuses in the width direction of the kneaded material and falls evenly, and unevenness in the growth range is less likely to occur. In addition, the fertilizer referred to in the present invention includes compost and effective bacteria in addition to general granular and liquid fertilizers.
