In addition, the configuration is such that the chain sliding of the right transfer chain 26a is abolished.

As a result, it is possible to scrape the cereals well. Costs are reduced due to the elimination of chain sliding.
As shown in FIGS. 27 to 30, the lubrication device 37 that is the lubrication of the combine 1 that trims the three rows is provided with an oil tank 37 a on the surface portion of the right pulling device 10 or the pulling pipe 39, or the right pulling device 10 or A gun stay 39b is fixedly provided on the upper frame 39a provided on the pulling pipe 39, and an oiling gun 37b is hooked and supported on the gun stay 39b. The oil supply gun 37b and the oil tank 37a are configured to be extendable and connected by providing a long oil supply hose 37c. When oiling to various places, the oiling gun 37b is removed from the gun stay 39b, the oiling hose 37c is extended to the oiling position, and the oiling gun 37b is operated to a predetermined position for oiling.

  For example, as shown in FIG. 30, the lubrication point may be, for example, as shown in FIG. 30, the feed chain 6 a part, the cutting blade device 8 c part, each scavenging device 16 a part, the root transfer chain 17 a part, and the left / right transfer chain 25 a. , 26a, and the left, right and middle pulling devices 9, 10, 38, etc.

Thereby, it is easy to lubricate the combine 1. It is possible to prevent accumulation of sawdust in the oil supply hose 37c. In addition, it is possible to lubricate the entire machine.
Conventionally, an auxiliary pulling device 40 as shown in FIGS. 36 to 38 is provided on the front lateral side of the left pulling device 9 of the left, right and middle pulling devices 9, 10, and 38 of the combine 1 for cutting the triple row. This is a configuration provided. The auxiliary pulling device 40 is provided with pulling lugs 40c mounted on the pulling chain 40b at predetermined intervals on the right and left pulling cases 40a so as to rotate in the front-rear direction. The pulling lugs 40c act on the front side. The pulling chain 40b is provided in a transmission case 40d provided in the upper part of the left pulling device 9, and is driven to rotate by the transmission mechanism 40e. As shown in FIGS. The disk type auxiliary pulling device 41 is provided.

  The disc-type pulling device 41 is provided on the front lateral outer side of the left pulling device 9 as shown in FIGS. In the lower part of the front side surface of the left pulling device 9, a transmission case 42 having a transmission mechanism 42a is provided, and a disk type auxiliary pulling device 41 is mounted on the transmission shaft 42b of the transmission mechanism 42a.

  A disk-shaped plate 41a of the disk-type auxiliary pulling device 41 is mounted on a transmission shaft 42b as shown in FIGS. In the vicinity of the outer periphery of the plate 41a, a pulling lug 41b that is rotatable at a predetermined interval is mounted. At the distal end of each pull-up lug 41b on the base side, a stand-up guide 41c is provided to stand up within a range of a substantially semicircular shape (approximately 180 degrees) that makes each pull-up lug 41b upright or lying down. The pulling lug 41b is in a standing state at one end of the standing guide 41c, and the pulling lug 41b is in a lying state in the other part on the other side. Further, in the standing state, the stopper 41d is provided to ensure the standing in the predetermined state. Each of the pulling lugs 41b is configured to be in a standing state for approximately 180 degrees from the lower portion on the front side.

Thereby, size reduction of the said combine 1 for three-row cutting is possible. Further, the auxiliary pulling device 41 can be reduced in size. The working range can be expanded.
The left, right, and middle pulling devices 9, 10, 38 of the combine 1 that cuts the three rows of rows are projected to the middle pulling device 38 as shown in FIGS. The intermediate cover 50a and the middle guide 50b for guiding the cereal stock side are provided at the bottom of the middle cover 43 as shown in FIGS. A protrusion 43a that protrudes rearward along the rotation trajectory of the pulling lug 41b, and a claw part 43b is provided at the lower end of the protrusion 43a to guide dust, mud, and the like downward. It is the structure to make.

  When the tip transfer lug 18c of the tip transfer device 18 is moved to the uppermost position as shown in FIG. 40, the middle cover 43 is moved to the uppermost position of the middle cover 43 and moved to the lowest lowered position. In some cases, the intermediate cover 43 is positioned at the lower end of the protrusion 43a.

  Thereby, by providing the protrusion 43a to the middle cover 43, the transfer passage is limited, and it is possible to stabilize the catching, prevent the spilling of the culm and prevent the culm from being in a cross state. Further, it is possible to smoothly guide downflow of sludge, mud and the like to the lower part. Furthermore, the cost can be reduced by reducing the number of parts.

  In the front part on the grain storage tank 7 side, as shown in FIG. 13, there is an operation room 44b formed by an operation room case 44a for starting, stopping and adjusting each part. A device 44 and a pilot seat 45 on which an operator who performs these operations are provided are provided. An engine 46 is placed on the upper side of the traveling chassis 2 below the pilot seat 45, and in the rear portion. The grain storage tank 7 is disposed. It is the structure which formed the body 1a of the combine 1 with these traveling devices 4, the reaper 3, the threshing machine 5, and the engine 46 grade | etc.,.

  As shown in FIG. 13, in the transmission path of the transmission mechanism 47a in the traveling mission case 47 mounted on the front end of the traveling chassis 2, a potentiometer type that detects the traveling vehicle speed based on its output. The vehicle speed sensor 47b is provided.

  On the rear side of the grain storage tank 7 for discharging the grains stored in the grain storage tank 7 to the outside of the machine, as shown in FIG. Discharge with a vertical installation, which is pivotably mounted, and is provided with a discharge spiral 49a that can extend and retract at the upper end of the discharge support cylinder 48. In this configuration, the auger 49 is disposed in the front-rear direction so as to be telescopic, pivotable up and down, and pivotable left and right.
