And the rotation arm 32 is a position when it stands by behind (the position where the rear cover 8b is closed) and a position when it is rotated forward (a position where the rear cover 8b is moved to the front side and opened). In any of the positions, the connecting portion 32b is configured to be at a position higher than the height position of the tip transport case 33 housing the grain supply port 2 and the tip transport lug 6c.

Therefore, the rear cover 8b is located in the space portion and can be attached and detached relatively easily.
Then, the rear cover 8b is provided with a front latch 34 provided on the upper side of the rotating arm 32 on a front clamp 34 provided on the lateral coupling rod 28 and a rear clamp 34 'provided on the threshing device 3 side. The tool 35 and the rear locking tool 35 'can be freely engaged and disengaged to lock the open position and the closed position.

  And as shown in FIG.1 and FIG.2, the rear cover 8b prepares the spacer 36 of a suitable width along the clearance gap between the rear-end edge and the front-end edge of the threshing apparatus 3, and attaches it freely. Therefore, versatility can be improved. For example, the dust-proof cover 8 is made for a triple type, and when assembled to a larger combine (4, 5 type), it is made possible by closing the gap with the spacer 36, Overall, significant cost reduction can be achieved.

  The dust-proof cover 8 constitutes two types, that is, for the non-cabinet combine shown in FIG. 10 and for the cabin-type combine shown in FIG. That is, the dust-proof cover 8 on one side (FIG. 10) has a raised portion 40 at the center position, and a headlamp 41 is attached to the front of the raised portion 40 to illuminate the front. As shown in FIG. 4, it is dedicated to a combine that does not have a cabin. On the other hand (FIG. 11), the cabin-type dust-proof cover 8 has a configuration in which the raised portion corresponding to the raised portion 40 is eliminated and the flat portion 42 is not provided and the headlamp 41 is not provided. Dedicated to the combine having 43. In this case, since the headlamp 44 is attached to the upper portion of the front surface of the cabin 43, the dustproof cover 8 does not require the headlamp 41.

  As shown in FIG. 10, the raised portion 40 is arranged so as to be shifted to the left side in the forward direction and is formed with a flat surface 45 on the right side so as to secure a forward view from the cockpit 46. In addition, when the flat surface 45 uses a transparent material, it can see through this and can confirm the conveyance state and front lower part of a cereal.

  Next, as shown in FIG. 1, the moving passage 10 is configured by providing a gap between the side edge A along the front-rear direction of the front cover 8a and the inner edge b of the cutting side cover 7. The side wall 9 of the rear cover 8b is formed so that it can pass freely. Therefore, the rear cover 8b is supported by the rear rotating arm 32, and the guide rails 30 and 30 'are supported and guided by the rollers 31 and 31' while being guided by the front cover 8b. It can slide while overlapping forward along the upper side. Reference numeral 47 denotes a handle.

  As shown in FIG. 12, the transmission 23 described above has an operation lot 50 pivotally connected to an upper portion of an operating lever 49 whose intermediate portion is pivotally attached to the surface of the case 48, and is shown at the lower portion. Do not shift shifter. Then, the operation lot 50 is raised and extends along the upper side of the cover 24, extends rightward through the inside of the front cover 8a, and is freely supported by the support 51 provided on the front and rear connection frame 25. ing. The grip portion 52 is attached by bending the outer portion slightly upward from the support position of the operation lot 50 described above, extending the hand from the cockpit 46 and gripping it, raising the cereal and raising the lug 19 of the device 4. The speed can be changed.

Next, the operation will be described.
First, the dust cover 8 has the rear cover 8b closed at the position shown by the solid line in FIGS. 1 and 2, and the rear locking tool 35 ′ is engaged with the rear clamp 34 ′ to be locked, The cereal conveyance device 6 is covered so that a dustproof function can be exhibited. Then, the engine is started and the traveling vehicle body 1 is moved forward while being transmitted to the rotating parts of the airframe to start work.

  Then, the grain straws in the field are subjected to the weeding action from the lower part by the front weeding straw 17 and then the action of the raising lug 19 that is raised upward and continues to rotate, and sequentially from the lying state. Caused by the upright state, the stock portion reaches the scraping device 6a and is scraped into the reaping device 5 side. The cereals are cut by the reaping device 5, the stock is held by the stock transport chain 6b, and the tip side is engaged with the tip transport lug 6c and sequentially transported upward. Then, the cereal is inherited from the handling depth adjusting chain 6d to the supply device 6e, is inherited to the starting end of the feed chain 12, and is supplied to the cereal supply port 2 of the threshing device 3. In this way, the cereals supplied to the threshing apparatus are subjected to the threshing action by inserting the head portion into the threshing apparatus 3 while the root is held by the feed chain 12, and the selected grains It is transported and stored in the Glen tank.

  During such a series of cutting and threshing operations, the dust cover 8 is moved from the upper position of the grain raising device 4 to the scraping device 6a, the stock transporting chain 6b and the tip transporting lug 6c behind it, and thereafter Since the handling depth adjustment chain 6d and the supply device 6e are covered, it is possible to prevent the dust generated by the grain transporting action from being directly scattered to the outside so as to prevent the outside air from being contaminated with dust as much as possible. It is possible to work while dust-proof.

  Further, as shown in FIG. 10, the dust cover 8 has the flat surface 45 formed on the right side thereof by shifting the raised portion 40 to the left side in the traveling direction, so that the front view from the cockpit 46 is sufficiently provided. There is an advantage that the work can be performed while monitoring the weeding state and the raising state. In addition, if it comprises on the flat surface 45 using a transparent raw material, since it can see through, it can confirm the conveyance state and front low part of a cereal, and it is more convenient.

  Furthermore, in the embodiment of the present invention, as shown in FIGS. 1 and 2, when a gap is formed between the rear end edge of the rear cover 8b and the front end edge of the threshing device 3 (for example, a three-row type). For example, it has been prepared to crush by preparing a spacer 36 with an appropriate width so that it can be used as a general purpose. It was possible to increase the cost and significantly reduce the cost. The dust cover 8 can be manufactured at low cost because it uses the front and rear connection frames 25 and the lateral connection rods 28 constituting the reamer frame 16 without configuring the supporting members separately. It is strong and stable and can slide smoothly.

  And the back cover 8b is higher than the height of the tip conveyance case 33 in which the connection part 32b of the rotation arm 32 accommodates the grain supply port 2 and the said tip conveyance lug 6c like an Example. Since it is configured at a position where there is a space, there is a feature that it can be attached and detached relatively easily at any position. The rear cover 8b has a relationship between the rotary arm 32 having the front and rear locking members 35 and 35 ', the front and rear connection frame 25, and the lateral connection rod 28 having the front and rear clamps 34 and 34'. Since the position does not change even when the pre-cutting processing device 13 is moved up and down, the lock is rarely inadvertently released, and the lock state is always maintained safely.

  Then, as shown in the embodiment, the grain raising apparatus 4 extends the hand from the cockpit 46 and operates the grip portion 52 relatively easily, and the shifter (not shown) is operated from the operation lot 50 and the operation lever 49. The transmission device 23 can be operated to change the speed according to the degree of lodging of the cereal, and an effective operation can be performed, and the operation lot 50 can be raised along the upper cover 24 to move the front cover. By extending in the right direction through the inside of -8a, it has a practical effect that does not hinder cereals passing below and does not catch swarf or the like.

  Further, in the case of the embodiment, the dust-proof cover 8 is a transmission case 21 that is disposed sideways above the device 4 by raising the front edge of the front cover 8a and raising the front edge of the front cover 8a as shown in FIG. A position where the left side of the front edge portion extends laterally to a position covering the transmission 23 and the right side covers the front / rear connecting frame 25. In order to improve the aesthetics of the design, the harness wired at this position can be covered and protected from rainwater and the like.

  Next, when carrying out maintenance of a series of cereal conveying devices 6, the dustproof cover 8 holds the handle 47 of the rear cover 8b and moves it from the position of the solid line in FIG. 1 and FIG. Move operation. Then, in the rear cover 8b, the rotating arm 32 rotates forward with the lower part as a fulcrum, and the left and right guide rails 30, 30 'are guided by the rollers 31, 31' on both sides. While moving, the threshing device 3 is opened sequentially from the cereal supply port 2 side. At that time, the rear cover 8b has a left side wall 9 in front of a moving passage 10 formed between the side edge i along the front-rear direction of the front cover 8a and the inner edge b of the cutting side cover 7. It passes smoothly to the side, reaches the position where it overlaps on the upper side of the front cover 8a, and can release the cereal conveyance device 6.

  When the rear cover 8b of the dust-proof cover 8 is opened by operating as described above, the cereal conveyance device 6 and its vicinity can be easily cleaned and maintained.
