Abstract

PURPOSE:To make possible to remove discharging roll from transmission shaft and make ready to change the discharging roll by vertically dividing roll case supporting horizontal transmission shaft of discharging roll of seed. CONSTITUTION:In a case of removing a discharging roll 1, butterfly bolt is removed and upper case 3b is upwardly removed, then both stopping rings 15 are removed from stepped parts 12 of the discharging roll 1, thus the discharging roll 1 is divided and becomes to be upwardly removed from a transmission shaft 2. By said method, removing operation is easy as the discharging roll 1 is able to be removed from the transmission shaft 2 in a state of the transmission shaft 2 supported by roll case 3 and changing operation of the discharging roll is readily performed.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a seed dispensing device for a seeding machine.

Background Art and Problems to be Solved by the Invention A sowing system having a horizontal transmission shaft supporting a feed roll that feeds out seeds, and a roll case that supports this transmission shaft and houses the feed roll. In the seed dispensing device of a machine, the roll case that supports the transmission shaft is usually molded in one piece, so when replacing the dispensing roll with another dispensing roll depending on the type of seeds or amount of seeds, etc., the transmission shaft can be replaced with the roll. It is necessary to remove it from the feeding roll inside the case,
The removal and removal operations are likely to be difficult due to rust and the degree of engagement between the transmission shaft and the delivery rolls, and therefore the replacement operation of the delivery rolls is not easy.

Means for Solving the Problems Regarding the Invention of Claim 1 This invention provides a roll case in which a feed-out roll (1) for feeding out seeds is housed and a horizontal transmission shaft (2) of the feed-out roll (1) is supported. (3) is a structure of a ladder feeding device of a seeding machine in which the transmission shaft (2) is divided into upper and lower parts so that it can be attached and detached in the vertical direction.

Effect of the invention The roll case (3), which is divided into upper and lower parts, is connected to the transmission shaft (2).
The transmission shaft (2) supports the feed roll (l).

When the roll case (3) is separated in the vertical direction, the power transmission shaft (2) and the delivery roll (1) can be removed from the roll case (3) in an upward or downward direction.

Effects of the Invention Due to such an action, as in the problem described above, the transmission shaft (2) can be moved from the feeding roll (1) in the roll case (3)
Instead of pulling out the transmission shaft (2), insert it into the feed roll (
After removing the transmission shaft (2) from the roll case (3) together with 1), the transmission shaft (2) can be removed from the feed roll (1), making it easy to remove and remove, and therefore making it easy to replace the feed roll. It is.

Means for Solving the Problems Regarding the Invention of Claim 1 This invention provides a feed-out roll (1) that has a horizontal transmission shaft (2) and is housed in a roll case (3) that supports this transmission shaft (2). ) is configured as a seed dispensing device of a seed sowing machine, which is divided as far as possible so that it can be attached to and detached from the transmission shaft (2) in the radial direction.

The feed roll (1) of the invention's split action structure is supported by a transmission shaft (2), and the transmission shaft (2) is supported by a roll case (3).

Once the payout roll (1) is separated, it can be removed radially from the transmission shaft (2).

Effects of the Invention Due to this action, instead of removing the transmission shaft (2) from the feed roll (1) in the roll case (3) as in the problem described above, the transmission shaft (2) is removed from the roll case (3).
3), the feed roll (1) can be removed from the transmission shaft (2), making it easy to remove and operate.
Therefore, the exchanging operation of this feeding roll (1) is facilitated.

Embodiment In addition, on the government side, a connecting rod (7) protruding toward the rear is provided at the upper end of a tilling device (6) that is towed by a tractor (5) to be movable up and down. (7
A left-right support rod (8) is coupled to the rear end of ), and a lower bearing portion (9) into which the left-right transmission shaft (2) is fitted from above is attached to the support rod (8). (9), the lower case (3a) of the roll case (3) can house substantially the lower half of the feed roll (1) supported by the transmission shaft (2).
are connected via a connecting part (lO).

The lower bearing portions (9) (9) of the lower case (3a) include
A transmission shaft (2) having a flat surface (2a) extending in the axial direction is supported, and a recess (11) on the outer peripheral surface of the transmission shaft (2) into which the seed is inserted is provided on the transmission shaft (2). Feeding rolls (1) (1) divided into two parts having step portions (12) (12) at both left and right ends are provided, and these feeding rolls (1) are divided into two parts.
) (1) have mating protrusions (13) (13) provided mutually, and these protrusions (13) (
13) into which the holes (14) (14) are inserted, and the stepped portions (12) of both the feeding rolls (1) (1).
(12) are respectively provided with locking rings (15) (15) for locking the release of both the feed rolls (1) (1).

On the upper side of the lower case (3a), a 0η transmission shaft (2
) An upper bearing part (16) for supporting the upper part (16) is provided by overlapping an upper case (3b) that houses almost the upper half of the feed roll (1), ) at the lower end of the lower case (3a), there are locking bins (17) (1
7) are provided with engaging portions (18) (18) that engage from above, respectively, and the upper case (3b) is connected to the lower case (3a) at the upper end of the rear surface of the lower case (3a). A butterfly bolt (19) is provided to connect the two, and a hopper (20) for storing seeds is provided above the upper case (3b).

The transmission shaft (2) is mounted on the left side wall of the lower case (3a).
Chain case (
21) is installed diagonally downward and near the rear, and this chain case (21)
A pressure roller (22) that suppresses sowing marks and is transmitted to the chain transmission mechanism is pivotally supported at the lower end of the mechanism, and a pressure roller (22) that suppresses sowing marks and is transmitted to the chain transmission mechanism is supported on the support rod (8). The inheritance body (23) that inherits the seeds is transferred to the support unit (24).
), and the lower end of this joint (23) is provided with a guide tube (26) having a seeding port (25) at the lower end.

Next, the effect will be explained. The pressure roller (22), which is grounded and towed, is transmitted to the delivery roll (1) via a chain transmission mechanism and a transmission shaft (2).

The seeds in the hopper (20) are fed out by the feeding roll (1), and are sown from the seeding port (25) into the plowed field through the lower case (3a), the inheritance body (23) and the guide pipe (26). This seeding trace is crushed by a crushing roller (22).

When removing the feed roll (1), attach the butterfly bolt (19) and remove the upper case (3b) upward, then attach both locking rings (!5) (15) to the feed roll (1). By separating from the stepped portion (12) (12), the feed roll (1) is divided and can be removed upward from the power transmission shaft (2). Conversely, when attaching the feed roll (1) to the power transmission shaft (2), the above-mentioned removal procedure may be reversed.

FIG. 4 shows another embodiment of the feed roll (1), in which a fitting groove ( 27)
(27) are provided respectively, and the stepped portion (12) has a bent portion (28) (27) that fits into the fitting groove (27) (27).
a pair of locking rings (,29) having (28) (29
) will be established.

FIG. 5 further shows another embodiment of the feeding roll (1), in which, in addition to the stepped portion (12) of the feeding roll (1), outer circumferential stepped portions (30) (30) are also provided at both left and right ends of the outer circumferential surface. A locking ring (31) (31) is provided which extends from the stepped portion (12) to the outer peripheral stepped portion (30), and in this case, the outer peripheral surface is locked by the locking ring (31). Therefore, the projection (13) and hole (14) can be omitted.
