Description

[Detailed Description of the Invention] The present invention relates to an improvement of a shovel for soil blocking.

As a shovel for soil blocks, the present applicant proposed in Utility Application No. 56-161588 a shovel plate which is attached to the lower part of the handle rod and is capable of scooping up and placing a group of soil blocks arranged in a matrix; The present invention proposes an extruded plate of a group of soil blocks arranged along the width direction of the shovel plate and provided on the upper part of the handle rod so as to be able to slide against the scooping edge of the shovel plate. In this shovel, the extrusion plate slides with a constant stroke, so if the total length of the soil block to be scooped changed, the most advanced block would sometimes protrude from the tip of the shovel plate, fall, and collapse. The reason why the total length of the soil block group changes is that it depends on the type of soil that is the material for the soil block.When soil with good compressibility is used as a material, the elasticity after forming is small, and the original forming There is almost no difference in size, for example, one side is 4.5
The length of six regular cubic blocks of cm is 268 to 270 mm as shown in Figure 4, whereas
When soil with poor compressibility is used as a material, it has a large elasticity after forming, and expands beyond its original size, resulting in a block group similar to the above, with its total length decreasing.
This is because L'=275 to 280 mm, resulting in a difference of 10 mm or more from the former. Also, since the soil that is used as the material for soil blocks is mixed with peat moss, humus, compost, water, etc., the compressibility and elasticity of the soil will change depending on the ratio of these mixtures. be.

Therefore, the present invention makes it possible to appropriately change the length of the shovel plate according to the change even if the total length of the soil block group after molding changes, so that the soil block group can be reliably scooped up and the ends of the soil block group can be scooped up. It is an object of the present invention to provide a shovel for soil blocking which prevents objects from falling and being damaged.

For this purpose, the present invention is characterized in that the sliding portion of the extrusion plate is provided with a stopper for regulating the sliding range thereof.

The present invention will now be described with reference to the illustrated embodiments.

The soil block group b shown in Fig. 1 is manufactured by a soil block machine (not shown), and the soil blocks are continuously carried out in a matrix and are transferred to the seedling raising box p shown in Fig. 2 without breaking them. For this purpose, a soil blocking shovel 1 shown in FIGS. 3 and 4 is used.

Soil Block B is a mixture of soil mixed with appropriate amounts of peat moss, humus, compost, water, etc., which is then compressed and cut into shapes.For example, one side is
It has a regular cube shape of 4.5 cm, and coating seeds such as cabbage, lettuce, and Chinese cabbage are sown in the center of the top surface. The seedling raising box p is used for raising pine-shaped seedlings for rice transplanters, and in the soil block machine, the dimension of one side of the soil block group B is determined to almost match the width dimension of the seedling raising box p. Therefore, the horizontal width of the shovel plate 2 of the shovel 1 for soil blocking is also approximately equal to the width of the seedling box p, and is designed to fall within that width. Also,
Soil block b has been transferred to seedling box p,
The soil block shovel 1 is also used when the seeds that have been sown in subsequent management are germinated and nurtured to grow into seedlings n, and when the transplanting period comes, the soil block group B is taken out from the seedling nursery box p.

The soil blocking shovel 1 has a sharp scooping edge 2a formed on one side of a rectangular shovel plate 2, and a low raised edge 2b is provided on the edge opposite to this scooping edge 2a, and the width direction of this raised edge 2b is The lower end 3a of the handle rod 3 is fixed at approximately the center position. The handle rod 3 is bent in a U-shape, with a short lower part 3a and a long upper part 3b reaching above the scooping edge 2a of the shovel plate 2. A tubular slide grip 4 is slidably inserted into the upper part 3b of the handle rod, and a push-out plate 5 for pushing out the soil block group B is fixed to the slide grip 4. This extrusion plate 5 has a flat surface and is arranged to be substantially orthogonal to the shovel plate 2, and its length in the left and right directions is the same as the left and right width of the shovel plate 2, or is slightly shorter than that. The lower edge 5a is in contact with the upper surface of the shovel plate 2, or is slidable with a slight gap therebetween.

A front stopper 6 and a rear stopper 7 are provided on the upper part 3b of the handle bar 3, located at the front and rear of the slide grip 4. Both stoppers 6 and 7 have retaining rings 6a and 7a that are slidable relative to the upper part 3b, respectively, and wing nuts 6b and 7b that fix the retaining rings 6a and 7a in their moving positions. The movement range of the plate 5 is restricted.

Soil block shovel 1 with such a configuration
In order to transfer the soil blocks B group to the seedling box P, as shown in Fig. 4, soil blocks B group with good compressibility and a standard total length L during molding must be moved using stoppers 6 and 7. The wing nuts 6b, 7b are set so that the extrusion plate 5 moves by a length L.
Also, because the compressibility of soil block B group is poor, it expands elastically after molding, and the total length of the expansion is
If L′ is long, stopper 6,
7 is adjusted using wing nuts 6b and 7b. Then, the slide grip 4 is lowered backward until it comes into contact with the stopper 7, and the soil block group B is scooped up from the scooping edge 2a of the shovel plate 2 onto the shovel plate 2 and moved into the seedling growing box p. During this move,
Apply the scooping edge 2a of the shovel plate 2 to the bottom of the seedling raising box p, and while pushing out the soil blocks b group through the extrusion plate 5 with the slide grip 4, move the shovel 1 backward and transfer them from the shovel plate 2 to the seedling raising box p. . Furthermore, when scooping up the soil block group b in which seedlings n have been grown in the seedling raising box p and supplying it to a transplanter (not shown), for example, it can be transferred in the same manner. At this time,
If you take out the first or second rows of soil blocks b group at the end of the seedling box p by hand, it will be easier to scoop them out.

Note that the stoppers 6 and 7 are not limited to those of the above-mentioned embodiments, but may be of any type as long as they can restrict the movement range of the slide grip 4 and the push-out plate 5 and can be adjusted in accordance with the entire length of the soil block group b.

Thus, according to the soil block shovel of the present invention, the movement stroke of the extrusion plate can be freely selected according to the total length of the molded soil block group, and the soil block group can be completely scooped up and transferred. This prevents objects at the ends of the soil block group from falling and damaging the blocks, and the transfer work can be carried out reliably and quickly.
