Problems solved by technology

[0013] In the structure of such Patent Document 1, due to the influence of the installation accuracy of the discharge box on the first support member, the forming accuracy of the discharge box, the assembly accuracy of the bracket and the first support member, etc., the rotation axis of the driven gear (Discharge shaft) and the rotation shaft of the drive gear (drive shaft for sowing) The distance (axis center distance) will be uneven
As a result, the meshing between the driven gear and the driving gear sometimes deteriorates

Embodiment Construction

[0118] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a side view of the agricultural spreading work vehicle 1 according to the first embodiment of the present invention.

[0119] The spreading work vehicle 1 is composed of a vehicle body 2 and a direct spreading device (particle spreading device) 8 arranged behind the vehicle body 2.

[0120] The vehicle body 2 includes a front wheel 4 and a rear wheel 5 that are paired on the left and right, and an engine 10 as a driving source of the front wheel 4 and the rear wheel 5. In addition, at a position between the front wheel 4 and the rear wheel 5 in the front-rear direction of the vehicle body 2, a driver seat 6 for an operator to sit in is provided. In front of the driver's seat 6, a steering wheel 7 for the operator to perform steering operations on the vehicle body 2 is arranged.

[0121] At the rear of the vehicle body 2, the direct spreading device 8 is arranged....

Abstract

The seed discharge device (9) provided by the direct sowing device has a discharge box (21). The discharge box (21) is arranged below the hopper containing the seeds, and the seeds are supplied to the discharge box (21). The discharge box (21) is provided with a discharge roller that gradually sends out the seeds by a prescribed amount. The discharge box (21) has a driven gear supporting part (left side wall (33)) and a driving gear supporting part (49). The driven gear support portion (left side wall (33)) supports the driven gear (30) which rotates integrally with the discharge drum. The driving gear support portion (49) supports the driving gear (31) meshing with the driven gear (30).

Description

Technical field [0001] The present invention mainly relates to a supporting structure of a gear used for transmitting driving force to a discharging part in a granular discharging device. Background technique [0002] A direct seeding device (particle spreading device) that gradually sends out seeds (granular solids) in small amounts and spreads them into the field is known. The direct sowing device is equipped with a hopper for holding seeds and a seed discharging device (granular discharging device). The seed discharging device is provided with a discharging box arranged below the hopper. The discharging box is provided with a discharging drum with discharging holes formed on the peripheral surface. By driving the discharging drum to rotate, the seeds in the hopper are gradually taken into the discharging hole in a small amount and then sent out and released on the ground of the field. [0003] In these direct sowing devices and seed discharging devices, the discharging shaft,...
