Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interplant weeder for man-powered fields which is continuously advanced by hand pushing to perform weeding between plants.

[0002]

2. Description of the Related Art Conventionally, for weeding in fields, human-powered hos capable of weeding around a plant and between plants are well known. Also,
The inventor of the present invention provides a human-powered weeding tool as shown in FIG. 15 as one capable of weeding between plants without damaging the crop.
It has already been proposed in Japanese Utility Model Application No. 6-7029 (invention name "herb blade").

As shown in FIG. 15, the human-powered weeding tool of the above invention is constructed by attaching a front end portion of a handle 33 to a support rod 34 protruding from the center of the upper side of the weeding blade body 32. The weeding blade body 32 is curved in a downward gentle slope in which the lower part gradually narrows toward the central part from the middle part connected to the upper side part that juts out the bifurcated spring tines 35 to the left and right, and the inner surfaces of both lower end parts pass through a small gap. Opposite each other, each terminal 36
And 37 have blade edges h directed in the direction of arrow B to fix the base portion and are arranged in a V shape. And the handle 33
The handle angle is set to about 40 degrees and the spring tine 35
When it is tilted in the direction B, the sickle blades 36 and 37 are arranged to contact the ground diagonally downward.

In this human-powered weeding tool, an operator holds the handle 33 with both hands, aligns the gap between the lower ends of the bifurcated spring tines 35 with the crop row, and grounds the sickle blades 36 and 37 to stand up (FIG. 14). Work is performed by pulling in the direction of arrow B). Then, the sickle blade 3 with the blade edge h touching diagonally downward
Nos. 6 and 37 cut shallowly into the ground and cut the weeds w around the plant base of the crop P. At this time, the crop is inside the small gap preceding the sickles 36, 37 and is not cut by the sickles.

Further, by the above-mentioned underground cutting, sickle blades 36, 3
The resistance that acts on 7 is the sickle blade 36,
A component force for displacing 37 inwardly is generated, and this component force resists the elasticity of the bifurcated spring tine 35 and the sickle blades 36, 3
The rear surface of the base portion of 7 is brought close to or abutted. Therefore, the blades at the bases of the sickle blades 36 and 37 enter between the plants and enable cutting of the weeds w between the plants. When the rear surfaces of the bases of the sickle blades 36 and 37 are brought into contact with each other and approach the location of the crop, the inner surface of the lower end of the bifurcated spring tine 35, which precedes the sickle blade, comes into contact with the plant base of the crop. The back contact of the base of the is separated and the crop is passed. At this time, the return elastic force of the second spring tine 35 works in the opposite direction to the component force of moving the sickle blade inward, weakens the force for pressing the plant base, and has an effect of preventing damage to the crop.

[0006]

The conventional human power ho is,
Weeding between plants is possible, but it stops when standing up
Due to the fact that it moves forward or backward repeatedly, not only is it inefficient, but it can also damage crops due to mishandling. FIG.
The human-powered weeding tool shown in 5 can be pulled lightly because the sickle blade advances in the shallow ground. Further, as described above, there is an advantage that inter-plant weeding can be carried out without damaging the crop by skillfully utilizing the component force of the cutting resistance of the sickle blade in the soil. However, since the work is a standing back work, it is less efficient than the forward work. Further, there is a drawback that the fork spring tines must be held while holding the handle to keep the cutting depth of the sickle blade shallow.

Therefore, according to the present invention, in order to realize an efficient weeding operation, a push forward operation is suitable, and in the above-mentioned weeding blade body capable of weeding between plants, the cutting depth of the sickle blade is kept shallow. It is aimed to provide a simple and efficient human inter-plant weeder for man-powered fields, which allows the work to be carried out by pushing forward continuously, noting that it is sufficient to provide sleds on both sides of the stock plant. .

[0008]

In order to achieve the above-mentioned object, in the human-power-plant interplant weeder of the present invention, a sled having a rectangular plate whose front end portion is upwardly concavely curved is provided side by side with a proper interval. Then, the inverted U-shaped arm is traversed between the left and right sleds so that both lower end portions are detachably attached to the rear end portions of the left and right sleds, respectively. Straight rods are projected rearward from both sides of the rear end along the longitudinal direction of the sled, and a handle is projected obliquely rearward and upward from the center of the top of the inverted U-shaped arm. And
Tine stoppers are provided so as to project on the upper surfaces of the left and right sleds in front of the lower end of the inverted U-shaped arm, and a ring portion at the front end is attached to the tine stopper so as to be pivotable and vertically movable, and arranged between the left and right sleds. As it is installed, it is concavely curved in a plan view and gradually approaches the center line of the facing intervals of the left and right sledges as it extends rearward, and the rear ends gradually lower toward the rear of the straight rods at the rear ends of the left and right sledges. The left and right spring tines, which are tilted and left and right facing each other through a small gap, are fixed to the left and right sickle blades with the blade edge h facing forward and obliquely downward, and the base is fixed to a shallow position lower than the left and right sleds. They are arranged in a V shape with respect to the direction.

Tine stoppers projecting from the upper surfaces of the left and right sleds at the front of the lower end of the inverted U-shaped arm form tine insertion holes obliquely outward with respect to the forward direction, and left and right spring tines are provided. A straight rod portion having an appropriate length with the upper surface being a plane may be used as a front end portion, and the straight rod portion may be inserted into the tine insertion hole and pressed from above to be attached.

Further, the right and left sleds are replaced by straight bars on both sides of the rear ends of the left and right sleds, and a rectangular plate is extended for an appropriate length so that the front and rear ends are respectively concavely curved upward.
It is also possible to attach both lower ends of the shaped arm to the longitudinal central portions of the left and right sleds. Further, both lower ends of the inverted U-shaped arm may be welded to the upper surfaces of the left and right sleds.

[0011]

[Operation] In using the above-mentioned human-field interplant weeder, the operator holds the handle with both hands and lifts it down to align the small gaps at the rear ends of the left and right spring tines with the crop line, and then slides the crop line. Ground the left and right sleds. And
When the worker is located between the ridges on the side of the crop and pushes forward while pushing the handle, left and right sleds slide on the ground surface on both sides of the crop. At this time, the upward concave curve of the front end of the sled reduces running resistance, and the straight bars protruding backward from both sides of the left and right sled rear ends along the longitudinal direction of the sled shallowly sinks below the surface of the sled and bends. To lose. Further, the left and right sleds keep the cutting depth of the sickle blade of the spring tine rear end whose front end is attached to the upper surface of the sled through the tine stopper.

As the left and right sleds travel, the spring tines exert downward elasticity on the left and right sickle blades which are fixed to the terminals after the spring tines and are shallower and lower than the straight rod at the rear end of the sled. The diagonal downward of the blade edge causes an underground penetration action, which allows the sickle blade to cut shallowly into the ground, enabling the cutting of weeds around the plant base of the crop. At this time, the terminal of the spring tine preceding the sickle blade prevents the crop located inside the small gap from being cut by the sickle blade.

Further, the resistance force acting on the left and right sickle blades due to the incision in the ground produces a component force for displacing the sickle blades inwardly due to the c-shaped arrangement of the sickle blades, as described in the prior art. , The back of the sickle blade abuts and the blade of the base enters between the plants, enabling the cutting of weeds between the plants, and at the crop location, the inner surface of the left and right spring tine terminals that precede the sickle blade contacts the plant base of the crop. While pushing the back side of the base of the sickle blade outward, let the crop pass. At this time, the restoring elasticity of the left and right spring tines works in opposition to the above-mentioned component force of moving the sickle blade inward, weakening the force of pressing the plant base to prevent damage to the crop. In addition, the sickle blade that cuts into the soil shallowly rubs the roots of the crop on the back side and gives proper physical stimulation to promote the growth of the crop.

The turning of the ring portions at the front ends of the left and right spring tines with respect to the tine stopper and the vertical movement enable the adjustment of the mounting gaps between the front ends of the left and right spring tine rear end portions and the mounting height adjustment. It enables adjustment of the height of the sickle blade, that is, the cutting depth of the sickle blade.

Tine stoppers protruding from the left and right sledges are provided with tine insertion holes obliquely outward with respect to the forward direction, and straight rod portions having the upper surfaces of the front ends of the left and right spring tines as planes are the tine. If it is inserted through the insertion hole and pressed from above to attach it, the front end of the spring tine should not be twisted in the tine insertion hole, and the front end can be moved in and out of the tine insertion hole. To Therefore, it is possible to change the length of the spring tine from the tine stop to the terminal by moving back and forth, change the elasticity of the spring tine, and change the facing gap between the left and right spring tine terminals.

When the right and left sleds are replaced with the straight rods on both sides of the rear end and a rectangular plate is extended and the front and rear ends are respectively concavely curved upward, the ground contact area is increased and the field is weak. It will not sink, and the upward concave curve of the rear end eliminates catching with the soil when the sled retracts, and smoothly retracts the sled. In addition, reverse U on the upper surface of the left and right sled
When both lower ends of the shaped arm are welded, the inverted U-shaped arm can firmly hold the facing interval of the left and right sleds.

[0034]

In the inter-strain herbicide of the present invention, first,
The worker stands near one side of the crop, lifts the weeder with a handle, crosses the row of crops, and connects the left and right sleds to both sides of the crop. Then, when pushing forward while pushing the handle, since the sleds are arranged on the left and right, it is possible to travel stably. At this time, the sled can be pressed against the surface of the ground by pushing the handle protruding obliquely upward and rearward to stabilize the traveling of the sled. In addition, the straight rod protruding rearward from both sides of the rear end of the sled can be shallowly sunk below the surface of the ground to prevent the sled from meandering. Therefore, it is possible to continuously and stably run just by pushing the handle, and the weeding work can be advanced forward with significantly higher efficiency than the conventional human-powered weeding tool used in the standing-up / backing work. For example, the weeding efficiency of a man-powered ho in a red bean field planted in a ridge of 60 cm was at most about 30 ares per day, but with this weeder, weeding at 150 ares per day was possible.

The inverted U-shaped arm having both lower ends attached to the left and right sleds across the left and right sleds allows the foliage of the crops to easily pass through the inner space thereof, and even in a field where the crops are growing. Allows weeding work without damaging the foliage.

In particular, the left and right spring tines are attached to the front ends of the left and right sleds, which project from the front ends of the sleds.
As it goes backward, the left and right sleds are arranged symmetrically so that they gradually come close to the center line of the facing interval, and the rear end is made to face through a small gap, and the blade edge is directed forward and diagonally downward at the base. By arranging the fixed sickle blades in the shape of a letter V in the forward direction at the shallow low position behind the sled, the blades at the bases of the left and right sickle blades entered between the plants as already explained in the prior art, and Weeding between plants can be done without damaging the plants.

In particular, according to the present invention, since the front ends of the spring tines are attached to the upper surfaces of the left and right sleds, the cutting depth of the sickle blade can be kept shallow and constant, so that the lateral roots of the crop can be cut. In addition, it is not necessary to perform the cutting depth of the sickle blade by holding the handle, and the weeding work can be facilitated.

Further, the front end of the spring tine is formed into a ring portion, and the tine stopper projecting on the upper surface of the sled can be swung and the vertical position can be adjusted, whereby the gap between the bases of the left and right sickle blades and the cutting depth of the sickle blades can be adjusted. Can be adjusted.
Similarly, if the upper surface of the front end of the spring tine is made into a straight rod, and this is inserted through the tine insertion hole of the tine so that it can be withdrawn and retracted, and the plane is pressed to secure it, the spring Since the length of the working portion of the tines is changed, the elasticity of the spring tines and the clearance on the rear surface of the base of the sickle blade can be adjusted. In particular, if you make the top surface of the straight rod flat and press it to fix it to the tine stopper, you can prevent the spring tine from twisting in the tine insertion hole, preventing fluctuations in the cutting depth of the sickle blade of the spring tine terminal. can do.

Further, as shown in the third embodiment, the left and right sleds are made into rectangular plates having a larger ground contact area than in the first embodiment, and the front end portion and the rear end portion are concavely curved so that they are soft. Since the sled does not sink even in a field with various soils, the handle can be pressed lightly. Further, due to the upward concave curve of the rear end portion, it is possible to smoothly move around in a field terminal or the like without being caught on the soil. Also, by welding both lower ends of the inverted U-shaped arm to the upper surfaces of the left and right sleds as in the case of the fourth embodiment, it is possible to firmly maintain the facing interval between the left and right sleds by the sled and the inverted U-shaped arm. , The work can be simplified.

The main parts of the inter-plant weeder are the left and right sleds, the inverted U-shaped arms, the left and right spring tines and the sickle blades at their ends, and the handle. Therefore, since the whole can be made light and easy to handle, it is possible to obtain a peculiar effect that weeding work can be performed even on a sloping land where a tractor cultivator cannot be used or a narrow field.
