Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high ridge forming machine provided with a ridge plate which swings on the right and left sides of an airframe for forming high ridges such as strawberries.

[0002]

2. Description of the Related Art A ridge forming device (ridge plate) for forming a high ridge is incorporated in a towing machine, and (a) power is separately transmitted to a general-purpose machine from a rotary attachment and a ridge forming device. Method (b) There is a method in which a ridge former is connected to a rotary body type transmission to transmit power.

However, in the case of (a), the power is transmitted from the PTO of the machine to the counter shaft once through the belt and the chain, and the power for sliding the ridge plate from the PTO is transmitted therefrom to reduce the slope. It takes the form of formatting. For this reason, there is a problem that the body cannot be made compact and the total length and the total weight increase. Due to the drive transmission system using a belt or the like, assembling and adjustment are difficult, and the power transmission efficiency is poor, so that the operation surface is uncertain and unstable. Furthermore, since the distance between the axle and the rotor axle is large, there is a problem that the plowing distance (the time to reach the specified deep tillage position) becomes large.

[0004] On the other hand, in (b), although the body is made compact and the transmission efficiency to the rotary side is improved, the second shaft drive transmission system is adopted via a chain, and the power for sliding the ridged plate. However, since the transmission surface cannot be improved, the disadvantage of (a) has not been completely solved.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described circumstances of conventional means, and further simplifies the structure and transmission efficiency based on the above-mentioned (b) form (rotary transmission). Improvement, reliable operation stability,
It is an object of the present invention to provide a high ridge forming machine which cuts off the swaying of a ridge plate from a rotor operating portion and further has economical efficiency.

[0006]

In order to achieve the above object, the present invention relates to an input shaft 4 transmitted from a motor M to the left and right of a cross shaft portion 2a of an inverted V-shaped rotary transmission 2 of the machine 1. And both ends 3a of the output shaft 3 obtained through the intermediate shaft 5 fitted with the clutch 6 are protruded.

[0007] Then, a crank 7 is connected to both outer ends 3a, and a couple extension end 8a is connected to the lower end of the crank rod 7a.
Is connected to the inner intermediate portion 9a of the ridged plate 9 via a bell crank 8 protruding, and an interlocking rod 10 is connected to the couple extension end 8a, and a second bell crank 11 is connected to a lower end of the interlocking rod 10. The inner lower part 9b of the ridged board 9 is connected through the intermediary.

Then, the operation of the clutch 6 interrupts the sliding movement of the ridged plate 9 so that the rotation of the rotor shaft 12 is always operated via the sprocket gear 15 fitted on the outer periphery of the output shaft 3. To form a high ridge forming machine.

[0009]

In FIG. 1 and FIG. 2, when the input shaft 4 is rotated by being driven by the prime mover M, the input gear 13a which is always meshed.
The intermediate shaft 5 rotates via the driven gear 13b and the output gear 14 fixed to the output shaft 3 which meshes with the gear 6a of the clutch 6 (pre-engaged clutch) mounted on the intermediate shaft 5, Rotary transmission 2 at both ends 3a
The output shaft 3 protruding left and right of the cross shaft portion 2a is rotated.

Then, the crank 7 connected to the outer ends 3a is operated, and a bell crank 8 having a couple extension end 8a protruding from the lower end of the crank rod 7a is provided at an inner middle portion of the ridged plate 9. 9a is reciprocated horizontally.

At the same time, the couple extension end 8a
The interlocking rod 10 linked to
The second bell crank 11, which connects the lower end thereof and the inner lower part 9b of the ridge plate 9, reciprocates the inner lower part 9b of the ridge plate 9 in the horizontal direction.

In this way, the slopes of the inclined high ridges are squeezed to the left and right sides as the aircraft travels. In the meantime, the rotation of the rotor shaft 12 is always continued through the sprocket gear 15 fitted on the outer periphery of the output shaft 3 to which the gear is transmitted from the intermediate shaft 5, but the sliding movement of the ridge plate 9 is controlled by the clutch 6. , The engagement between the clutch gear 6a and the output gear 14 can be interrupted and stopped. This plays an important role in removing the resistance in guiding the rotor pawl to the plowing depth at which the completed ridge is formed, and reducing incomplete ridges.

[0013]

The present invention is as described above. The output shaft is provided on the left and right sides of the inverted V-shaped transmission case of this machine, and the ridge plate is directly driven (sliding) by the interlocking of the crank and the bell crank. Therefore, power transmission efficiency is high, and reliable and stable operation can be obtained. In addition, since the engagement of the clutch gear and the output gear is interrupted by the clutch operation and only the sliding movement of the ridge plate 9 is stopped, as described above, only the rotor pawl work is required, so that the resistance during forward running is reduced. Can be removed to reduce incomplete ridges.

[0014] Since a rotary body type transmission is basically employed, installation and adjustment are easier than that of the belt and chain type, and the body can be made compact and lightweight. As a result, there is an advantage that correction can be performed quickly and easily even when a deformation such as bending of the ridge occurs during the ridge work. Furthermore, as described above, since the distance between the axle and the rotor shaft is narrow, the plowing distance (time required to reach the specified deep tillage position)
Is also advantageous in that the amount of

Since the manufacturing cost is relatively low, it is sufficiently economical to use a dedicated machine as compared with a conventional machine using a general-purpose machine.
