Abstract

PROBLEM TO BE SOLVED: To provide a seeding device enabling stripe seeding of small seeds which can be easily used in home gardens, home gardening or the like, as it is hard for people to grab small seeds with the fingers and seed little by little.SOLUTION: A hollow in an intermediate area of a cylindrical seed container 1 which has one and as a seed entrance and the other end as a seed exit is narrowed to several millimeters. The cylindrical wall at the narrowest hollow is gouged into an arc shape as much as a part of the cylindrical wall can be left to be a seed feed hole, and a handle 4 is fixed to the side opposite to the seed feed hole. A roller 2 with a brush-like outer peripheral surface has a contact with the seed feed hole, and a roller shaft 3 is set so that the brush can touch and spread in the seed feed hole and is fixed to the handle 4.

Description

  The present invention relates to a seed drill capable of stroking small seeds.

  Small seeds are difficult to pick up with small intervals because they are difficult to grasp with your fingers. The simplest method is to drop a small amount of seeds in the palm of your hand and then twist your wrist to drop it to the place you want to crawl, but you need to get used to sowing it at regular intervals. Another way known to home gardening and home gardening enthusiasts is to fold a thick postcard-like paper, place a small amount of seeds in the “V” shaped groove, Just above, with the tip of the paper slightly lowered, if you apply fine vibrations to the paper with your finger etc., the seed will move gradually toward the tip, so it will move well while controlling well and dropping the seed little by little Although it is a way of doing it, it requires some habituation and there is a risk that the seed will be blown off by the wind.

  It is also known that a rotating body made of an abacus ball-shaped elastic member is inscribed in an opening of a rhombus-shaped container made of a partition plate having a V-shaped feed groove and an open part (patent) Reference 1).

JP 2009-254277 A

  As a first problem in Patent Document 1, the proposed seed sowing device is for counting seeds, and does not perform an operation of sowing seeds in a field or the like at regular intervals. That is, the operation of the seed sowing machine is until the seed is sent out and temporarily placed on the temporary tray, and the seed sowing operation is realized by twisting the wrist having the seed sowing machine. Therefore, the sowing operation is not much different from the sowing operation on the palm, and continuous sowing is not possible. If multiple seeds are temporarily placed on a temporary tray and the wrist is twisted and the seeds are sown, if the wrist is twisted near the place to be sowed, the seeds are concentrated in one place, and the wrist is twisted away from the place to be sowed The seeds are dispersed and so-called streaking is not possible.

  As a second problem in Patent Document 1, after the seed is sent out by a rotating body made of a resilient member, the periphery of the rotating body becomes an open portion where nothing comes into contact. Therefore, the seed rotates while attached to the resilient member. May spill out and accurate counting is not possible.

  As a third problem in Patent Document 1, since the delivery port is open, when the seed delivered by the rotating body bounces at the exit, it may scatter from the delivery port to the surroundings, and accurate counting cannot be performed.

  As a fourth problem in Patent Document 1, since a rotating body made of a resilient member is not a structure that can be easily assembled, the resilient member is expected to be worn or deformed during storage, and sufficient performance cannot be exhibited at the next use. There is concern.

  In a seed drill composed of a seed container, a roller, a roller shaft, and a handle, the seed container has a cylindrical shape, the hollow at the center is narrowed, and the handle is fixed in a shape orthogonal to the narrowest portion. The cylindrical wall where the cylindrical hollow becomes the narrowest at the fixed part of the seed container and the handle is formed in an arc shape from the opposite side of the handle to provide a seed feeding port. In order to place the roller in contact with the cut surface of the seed feeding port, the roller shaft is placed in front of the seed feeding port by bending it into a "U" shape perpendicular to both the seed container and the handle. Are attached to the roller shaft with nuts.

  The seed container has a cylindrical shape of several tens of centimeters, one end is used as a seed inlet / outlet, a lid is attached, and the other end is used as a seed outlet. The hollow inner diameter of the seed container is several centimeters at the seed inlet / outlet, gradually narrows the hollow from the seed inlet / outlet to the middle region, and is several millimeters at the narrowest part, and then the hollow inner diameter is slightly expanded and headed toward the seed outlet. Mold like so. As described above, the seed feeding port is formed by cutting out and cutting the cylindrical wall of the seed container in an arc shape, but the seed feeding passage is provided by leaving a part of the cylindrical wall at the deepest part.

  The outer peripheral surface of the roller is shaped like a brush and has an elastic force. When the outer peripheral surface of a roller having a brush-like elastic force is brought into contact with the seed feeding port without any gap, the brush fibers spread in the seed feeding path and block the seed path. This is a seed drill that can be used to strain small seeds.

  When the roller is turned while moving the seed outlet, the seed is seeded while maintaining a certain distance between the seeds, and so-called stroking is possible, so the first problem pointed out in Patent Document 1 is Solvable.

  The seed staying in the seed feed passage is pushed out by the elasticity of the brush on the outer peripheral surface of the roller, but even if it rotates with the seed attached to the brush fiber, it is scraped off by the inner wall of the seed feed port, so that the patent document The second problem pointed out in 1 can be solved.

  Since there is a cylindrical seed passage from the seed feeding port to the seed outlet, the seed dropped from the seed feeding port falls near the seed outlet, so the third problem pointed out in Patent Document 1 can be solved. .

  Since the roller is attached to the roller shaft with a nut, the roller is detachable. If the roller is removed during long-term storage, the brush on the outer peripheral surface of the roller can be prevented from being loosened and deformed, and the elastic performance can be maintained, so that the fourth problem pointed out in Patent Document 1 can be solved.

Perspective view of the present invention The perspective view which showed attachment of the roller axis | shaft in this invention clearly The perspective view of the seed container which is a part of this invention The disassembled perspective view which shows the state which removed the roller in this invention The perspective view which shows the utilization condition of this invention Sectional view of a seed feeding mechanism that is a part of the present invention

  An embodiment of the present invention will be described with reference to FIGS. 1 and 2 are perspective views of the present invention. The seed drill is composed of a seed container (1), a roller (2), a roller shaft (3), and a handle (4), and fixes the seed container (1) and the roller shaft (3) to the handle (4). Mount the roller (2) on the roller shaft (3).

  Each part of the seed container (1) shown in FIG. 3 will be described. The seed container (1) is cylindrical and has one end as a seed inlet / outlet (12) and a lid (11), and the other end as a seed outlet (14). The seed container (1) includes a lid (11), a seed inlet / outlet (12), a cylindrical portion (13) extending from the seed inlet / outlet (12) to the seed outlet (14), a seed feeding port (15), a seed feeding passage (16 ). Although the lid (11) has shown the screw system, it can be integrated with the seed container and can be opened and closed. The length of the seed container (1) is several tens of centimeters, and the hollow inner diameter is several centimeters at the seed inlet / outlet (12). The hollow is gradually narrowed from the seed inlet / outlet (12) to the middle area, and the middle area is the narrowest number. Immediately after that, the inner diameter of the hollow is expanded and molded so as to go to the seed outlet (14). The seed feeding port (15) is a cross section in which the hollow cylindrical wall is narrowed in the middle region of the cylindrical portion (13) and is cut out from the outside so as to leave a part of the cylindrical wall. is there. The seed feeding port (15) leaves a part of the cylindrical wall even at the deepest part and secures the seed feeding passage (16).

  In FIG. 3, the hollow from the seed inlet / outlet (12) to the intermediate region is shown as a conical shape, but other shapes may be used as long as the hollow gradually narrows. Moreover, although the shape of the cylindrical part (13) from the seed feeding port (15) to the seed outlet (14) is shown as a straight cylinder, when it is made a member such as a removable silicon tube or vinyl tube, the seed It is easy to clean the seed container (1).

  FIG. 4 is an exploded perspective view showing a state where the roller is removed. The configuration of the seed container (1) and the handle (4) will be described. First, the rod-shaped handle (4) is fixed in a shape substantially orthogonal to the opposite side of the seed feeding port (15) across the seed feeding passage (16) of the seed container (1). The length of the handle is around 10 cm that can be grasped with one hand, and the thickness of the handle is several tens of millimeters.

  The configuration of the roller shaft (3) and the roller (2) shown in FIG. 4 will be described. A roller (2) has a bearing and provides a brush-shaped outer peripheral surface. When the roller (2) is mounted on the roller shaft (3), the brush fiber (21) of the roller (2) spreads from the seed feeding port (15) and closes the seed feeding passage (16). (3) is placed in front of the seed feeding port (15) and in a direction perpendicular to both the seed container (1) and the handle (4), and its roller shaft is bent into a "U" shape. Fix it. FIG. 4 shows an example in which the roller shaft is bent into a “U” shape and is nut-tightened to the handle (4), but there is also a method in which the roller shaft is bent into a “?” Shape and bonded through the center line of the handle. . Pass the roller (2) through the roller shaft (3) and attach it with a locking nut (5) so that it comes to the front of the seed feeding port (15).

  In the above description of the embodiment, the seed container (1), the roller shaft (3), and the handle (4) have been described as separate ones, but the seed container (1), the roller shaft (3), and the material of the handle (4) are used. By unifying metal and plastic, the seed container (1) and the handle (4) can be molded integrally, or the seed container (1), the roller shaft (3) and the handle (4) can be molded integrally. It becomes. If plastic is used as the material, the seed container (1) can be made transparent or translucent, and the state of the seed can be easily understood. In addition, a method of driving the roller (2) instead of turning it with a finger is conceivable, and a method of rotating the roller (2) by pulling a lever or a trigger is also conceivable. Although a brush-like form is shown as the elastic member on the outer peripheral surface of the roller (2), substantially the same effect can be obtained even when the elastic member is made of a sponge-like synthetic foam or an elastic resin.

  The present invention has the above structure. FIG. 5 is a perspective view showing a utilization state of the present invention. FIG. 6 is a cross-sectional view of the seed feeding mechanism. When seeds are put from the lid (11) of the seed container (1) and the seed outlet (14) is brought close to the ground where seeds are to be seeded, the seed (S) in the cylindrical part (13) Although it is going to fall to (14), the passage is blocked by the brush fiber (21) on the outer peripheral surface of the protruding roller (2) in the seed feed passage (16) and stays there. When the roller (2) is slowly turned in the direction of rotation (P) with a finger, the seed that has stayed in contact with the brush fibers (21) on the outer peripheral surface of the roller (2) is pushed out little by little in the seed feed passage (16). It is. The extruded seed passes through the hollow portion of the cylindrical portion (13) by gravity and falls to the seed outlet (14). When the seed outlet (14) is moved close to a place where the seed is desired to be sprinkled and the roller (2) is rotated, the seed is sprinkled while maintaining a certain distance, that is, so-called streaking. Although the seed (T) may rotate while the seed (T) is attached to the brush fiber (21), the seed (T) is a seed because of the structure in which the brush fiber (21) comes into contact with the end of the seed feed passage (16). It is scraped off by the inner wall of the feed passage (16) and falls to the seed outlet (14).

  Sowing is a seasonal event. When storing for a long time without using a seed drill, remove the locking nut (5), remove the roller (2), and store it so that no external force is applied to the brush fibers (21) on the outer peripheral surface of the roller (2). Thus, the brush fiber (21) can be prevented from being loosened and deformed, and sufficient performance can be exhibited at the next use.
