Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is configured such that the grain is packed and collected through a grain discharge cylinder that communicates with the lower portion of the grain storage hopper, and the grain passage is provided with a shutter plate that can be opened and closed. Regarding the recovery device.

[0002]

[Prior Art]

 In the above grain collecting apparatus, conventionally, a shutter support member that slidably supports the shutter plate is made of a sheet metal material, and, for example, as shown in FIG. 6, a spring support bracket is provided on a side surface of the shutter support member 41. 42, the coil spring 43 is installed in the bracket 42, the ball 44 is pressed and urged toward the shutter plate, and the ball 44 engages with the recess 45 formed in the shutter plate to close and open the shutter plate. A detent mechanism for holding the position and the position respectively was constructed.

[0003]

[Problems to be solved by the device]

 However, according to the above-mentioned conventional structure, since the detent mechanism for holding the position of the shutter plate is configured, there is a drawback that the number of parts is large, the number of assembling steps is large, and the cost is high. The present invention aims to solve the above-mentioned problems.

[0004]

[Means for Solving the Problems]

 The feature of the present invention is that in the grain collecting device described at the beginning, a cylindrical shutter support member that slidably supports the shutter plate is made of a synthetic resin material, and the shutter support member is laterally mounted. An integrally formed locking part that holds the shutter plate in the closed position and in the open position by the engagement part formed on the shutter plate engaging the cantilevered slide support part There is a point.

[0005]

[Action]

 Since the shutter support member is made of synthetic resin material, it can be manufactured by integral molding, and the work of bending or welding the sheet metal material is not required, and the shutter support member is integrally molded with the locking part. By doing so, the cantilevered support part that forms this locking part elastically deforms the synthetic resin itself, the engagement part on the shutter plate side rides up and passes through, and the position is held by engaging with the locking part. By doing so, the shutter plate can be held in the open / closed position.

[0006]

[Effect of the device]

 Therefore, by rationally configuring the material of the shutter support member, the parts can be easily manufactured, and the mechanism for holding the shutter plate in the open / close position can simply form the engaging portion. In addition, the structure can be simplified and the cost can be reduced because there is no need to provide other members for engagement.

【Example】

 Embodiments will be described below with reference to the drawings. FIG. 5 shows a grain bag packing and collecting section of the combine. The supporting rod is provided with a hopper 2 for storing the grains that have been threshed in the threshing device 1, and a collection bag 3 for collecting the grains cantilevered from the side wall of the threshing device 1 below the hopper 2. It is deployed in a state of being held in the upright position by 4. At the lower part of the hopper 2, a discharge tube 5 for discharging the grain is provided in communication with the discharge tube 5, and at the upper part of the discharge tube 5, a shutter plate 6 for opening and closing the grain discharge passage is slidably movable in the lateral direction. It is provided.

As shown in FIG. 4, a shutter support member 7 slidably supporting the shutter plate 6 is provided in a tubular shape, and an upper part thereof is connected to a discharge port 8 formed in the hopper 2, and a lower part thereof is provided with the above-mentioned member. The discharge cylinder 5 is connected. The shutter plate 6 is configured to be slidably placed and supported on the upper side of the upper edge 7a, and the shutter plate 6 made of a sheet metal is attached to the L-shaped extending portions 7b and 7b extending from the outer side surface thereof. The floating prevention members 9 and 9 are screwed.

The left and right sides of the shutter plate 6 are bent downward, and a closed space S is formed between the shutter plate 6 and the L-shaped extending portions 7b and 7b. This closed space S is a space for arranging a spring for closing and urging the shutter plate 6 in the case of the automatic opening / closing operation type.

As shown in FIG. 3, the connecting structure of the discharge cylinder 5 and the shutter support member 7 is formed by externally fitting the discharge cylinder 5 to the lower side cylinder portion of the shutter support member 7. A clip member 10 made of a synthetic resin material is inserted and inserted through the insertion hole, and after the insertion, a pin 11 is press-fitted in the center of the clip member 10 to expand the tip locking portion 10a of the clip member 10 to prevent the clip member 10 from coming off. It is designed to facilitate connection work. When disassembling, the pin 11 is screwed out and the grip member 10 is removed. The shutter support member 7 is made of a synthetic resin material, and a slide support portion 7c is extended in a cantilever manner from the side edge of the upper edge 7a on the slide direction side of the shutter plate 6 by integral molding. An arcuate projection 12 [an example of a locking portion] is formed on the upper surface of the slide support portion 7c. Further, the shutter plate 6 has a pair of engaging recesses 13 which are fitted into the protrusions 12 and engaged at the closed position for blocking the grain passage route and the open position for opening the grain passage route, respectively. , 13 [an example of an engaging portion] are formed. With this configuration, when the shutter plate 6 is manually slid, the projection 12 contacts the lower surface of the shutter plate 6 and the slide support portion 7c is displaced downward due to the elastic deformation of the synthetic resin. However, when the shutter plate 6 is allowed to slide and reaches a predetermined open / closed position, the protrusion 12 enters one of the engaging recesses 13 and 13 as shown in FIGS. The shutter plate 6 is held in position by being engaged.

[Other Embodiments] An engaging recess 13 [another example of the engaging portion] is formed on the shutter plate 6 side, and a protrusion 12 [another example of the engaging portion] is formed on the supporting portion 7c side. You can do it.

It should be noted that reference numerals are added to the claims of the utility model for easy comparison with the drawings, but the present invention is not limited to the configuration of the accompanying drawings by the entry.
