Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to improvement of the transmission mechanism of each part in a seeding device.

[Prior art and its problems] Each part of a conventional seeding device, specifically, a conveyor, a seedling box supply mechanism, a bed soil supply mechanism, a bed soil leveling mechanism, a bed soil compaction mechanism, a seeding mechanism, and a seed compaction mechanism There are two types of transmission mechanisms, such as the soil-covering mechanism, the sown seedling box collection mechanism, and the like. The first means is to install a drive motor for each mechanism and drive each mechanism by an independent drive mechanism.Another means is to drive each mechanism by a belt,
Another method is to connect them by a chain, incorporate a tension pulley, a clutch mechanism, etc., and operate them using a common drive source.

The former allows the entire device to be put together neatly, but since a motor is used for each mechanism, the cost is inevitably high, and the latter has differences in height between each mechanism, making work difficult. Since the speeds and other factors differ, the structure is complicated due to the rotation of belts and chains, and the use of tension pulleys and clutch mechanisms requires a large number of parts, and it is necessary to cover these. Although there are some issues, such as the fact that there are many problems, it is recognized that there is an economical effect in that fewer driving sources are required.

The purpose of this invention is to erect transmission shafts corresponding to each mechanism from a single common drive shaft via a bevel gear structure, and to connect these transmission shafts to the operating parts of each mechanism. An extremely simple transmission mechanism that solves the technical issues and allows the speed of each mechanism to be adjusted by adjusting the number of teeth on the bevel gear, and the drive direction to be adjusted by changing the orientation of the bevel gear with respect to the drive shaft. The purpose of this invention is to provide a device that allows each mechanical part to be operated by the following methods.

[Means for Solving the Problems] The configuration of the present invention that solves the problems of the prior art includes horizontally suspending a carrier for transporting seedling boxes on a machine frame, and
At least a mechanism for supplying soil to the seedling boxes, a mechanism for leveling the soil, a compaction mechanism for the soil, a sowing mechanism, a soil covering mechanism, etc. are arranged in the machine frame in order from the upper side of the conveyor to the lower side, In the transmission mechanism of each part of the seeding device in which the above-mentioned respective mechanisms are linked by a common drive source, a long drive shaft 6 in a horizontal position that is rotationally driven by the drive source of the carrier is connected to the longitudinal axis of the machine frame. On the other hand, a bevel gear that can be moved and fixed along the drive shaft is provided on the drive shaft 6 portion corresponding to each of the mechanisms, and each bevel gear is provided with a bevel gear that can be moved and fixed along the drive shaft. Bevel gears at the lower ends of transmission shafts 18, 19, and 20 in a vertical position connected to the parts are meshed with the respective parts.

[Example] Details of the embodiment of the present invention will be explained with reference to the drawings.

A pulley 8 is provided at the upper end of the drive shaft 6, and this is connected to a pulley 10 of a motor 9 installed in the machine frame 1 by a belt 11, so that the drive of the motor 9 is controlled by the drive shaft. 6.

As is clear from FIG. 1, the drive shaft 6 is
A bed soil supply mechanism 1 installed along the longitudinal direction of the machine frame 1 and mounted on the machine frame 1.
2. It is designed to reach all areas of the constituent mechanisms necessary for the seeding device, such as the seeding mechanism 13 and the soil covering supply mechanism 14. In this embodiment, the three mechanisms 12, 1
Although only examples 3 and 14 are shown, other mechanisms such as a seedling box supply mechanism, a bed soil leveling mechanism, a bed soil compaction mechanism, a seed compaction mechanism, and a sown seedling box collection mechanism are provided. These illustrations are omitted.

Bevel gears 15, 16, 17 are provided at each portion of the drive shaft 6 corresponding to the bed soil supply mechanism 12, seeding mechanism 13, and covering soil supply mechanism 14, respectively. Bevel gears 21, 22, and 23 provided at the lower ends of transmission shafts 18, 19, and 20 erected on the machine frame 1 are brought into mesh with each other. Further, a bevel gear 2 is provided at the upper end of each of the transmission shafts 18, 19, 20, respectively.
4, 25, and 26, and connect this to each mechanism 12,
13, 14 are meshed with bevel gears 30, 31, 32 of actuating parts 27, 28, 29, so that the rotational drive of the drive shaft 6 is transmitted to the respective mechanisms 12, 13, 14 separately. It is. Furthermore, the lengths of the transmission shafts 18, 19, and 20 are the same as those of the respective mechanisms 1.
The length can be adjusted to suit the functions of the mechanisms 12, 13, and 14, and the length of each mechanism 1 can be adjusted according to the speed of the actuating parts 27, 28, and 29 of each mechanism 12,
The desired speed can be obtained by adjusting the number of teeth of the bevel gears corresponding to 2, 13, and 14. Furthermore, like the bed soil supply mechanism 12, the operating parts 2 of other mechanisms 13 and 14
8 and 29, the bevel gear 15 attached to the drive shaft 6 may be oriented in the opposite direction to the other bevel gears 16 and 17, as shown in the figure.

Further, as is clear from FIGS. 2 and 3, each of the transmission shafts 18, 19, 20 is supported by a bearing member 33, and a flange portion 34 provided at the lower part of this bearing member 33 is attached to a bolt 35. Therefore, it is attached to the machine frame 1. As shown in FIG. 3, the machine frame 1 is formed with a long hole 36 that extends in the axial direction of the drive shaft 6, and the transmission shafts 18, 19, and 20 are inserted into this long hole 36. , each of the mechanisms 1
The transmission shafts 18, 1 are installed at the mounting positions of the bevel gears 30, 31, 32 of the operating parts 27, 28, 29 of 2, 13, 14.
The bevel gears 24, 25, 26 of 9 and 20 can mesh with each other in a corresponding manner. Therefore, the flange portion 34 of the bearing member 33 is also formed with an elongated hole 37 oriented in the axial direction of the drive shaft 6, so that the bearing member 33 can be easily attached with bolts 35. Furthermore, the bevel gears 15, 16, 17 attached to the drive shaft 6 can be slid relative to the drive shaft 6 by loosening the tightening bolt 38. Also, bevel gears 15, 16, 17
As a means for preventing the drive shaft 6 from rotating along the circumferential surface of the drive shaft 6, the drive shaft 6 may be formed into a polygonal shape, or
Alternatively, it is desirable to add a keyway or key.

[Effects of the Invention] As described above, according to the configuration of the present invention, the following effects can be obtained.

(a) Drive transmission to the operating parts of each mechanism required for the seeding device, such as the bed soil supply mechanism installed in the machine frame, is via a single drive shaft installed along the machine frame and bevel gears. This can be done using an upright transmission shaft, and the structure can be simplified compared to conventional techniques.

(b) By adjusting the length of the transmission shaft, it is possible to easily accommodate differences in height of each mechanism.

(c) By changing the direction of the bevel gear provided on the drive shaft, it is possible to set the rotation direction corresponding to the operating part of each mechanism.

(d) By changing the bevel gear ratio, the transmission speed corresponding to the operating part of each mechanism can be obtained.

(e) Since the bevel gears 15, 16, and 17 can slide relative to the drive shaft 6, after each mechanism is positioned and set relative to the machine frame, the bevel gears provided at the lower end of the operating shaft of each mechanism are The bevel gear 15,1
6 and 17 can be meshed while adjusting the slides, which not only simplifies assembly, but also allows for easily changing the installation position of each mechanism relative to the machine frame.
