[Constitution] In a combine receiving grain from the threshing section A and mounting a grain tank B axially mounting the discharge conveyor 1 in the inner lower part, the weight of the grain tank B serves as a main load portion. Load cells 5a and 5b, which serve as sensors for displaying weight, are provided between the support members 2 and 3 on both sides which support both ends of the discharge conveyor 1 and the chassis 4a and 4b below the support members 2 and 3, respectively. It is a thing.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a combine grain weight measuring device capable of measuring the weight of grain put into a grain tank mounted on an airframe.

[0002]

[Prior art]

 Conventionally, in a combine that is configured by receiving a grain from the threshing unit and mounting a grain tank equipped with a discharge conveyor at the inner lower part, when a grain becomes full in the grain tank, a sensor detects it. It is known that the operator can be notified.

[0003]

[Problems to be solved by the device]

 However, it is not possible to know how much weight the grain in the grain tank is during the work. For example, when working in a wetland, if the work is done until the tank is full, the weight will increase. In this situation, the aircraft sinks to the rice field and becomes unprogressable, and when weighing after harvesting, it is troublesome because it must be discharged from the Glen tank and then weighed with a weighing machine. It was

[0004]

[Means for Solving the Problems]

 The present invention has been devised so as to solve such a problem and to effectively measure the weight of the grain in the grain tank during the work. Therefore, the grain is received from the threshing section A and the lower inner side In a combine configured by mounting a Glen tank B on which the discharge conveyor 1 is mounted, the weight of the Glen tank B mainly serves as a site to support both ends of the discharge conveyor 1 and both supporting members on both sides. Load cells 5a and 5b, which serve as sensors for displaying weights, are respectively interposed between the second and third chassis 4a and 4b below them.

[0005]

[Effect] Therefore, during combine operation, the weight of the grain put into the grain tank can be detected by both load cells below both sides of the grain tank and can be effectively measured at all times. When the weight does not settle, the aircraft can be moved to discharge the grains in the Glen tank, or the grains in the Glen tank can be weighed and discharged as they are.

【Example】

 2 and 3 schematically show the entire combine, in which a threshing section A equipped with a handling cylinder 7 and the like is mounted on a machine body supported by both crawlers 6, and a scraping section is provided in front of the threshing section A. A cutting section C equipped with a pick-up reel 8, a cutting blade 9, a scraping auger 10 and the like is provided via a feeder chamber 11, and a seat 12 and a vertical column 13 are provided on the right side of the feed chamber 11. A cabin D with an interior is provided, and behind the cabin D, on the lateral side of the threshing section A, grains can be loaded from the threshing section A through the fried cylinder 14 and discharged to the lower part. A Glen tank B equipped with a conveyor 1 is provided, and behind the Glen tank B is provided an engine section E equipped with a conveyer conveyor 15 communicating with the discharge conveyer 1 and an engine 16, and the conveyer conveyer 15 is provided. Vertical auger cylinder 17 communicating with the end of From the upper end to configure similarly conventional type structure by extending the discharge auger tube 18.

The Glen tank B is erected so as to be rotatable about the up and down vertical fulcrum shafts 19 and 20 located on the rear outer side of the Glen tank B. The end portion of the discharge conveyor 1 is pivotally supported. The end of the bracket 22 extending from the bearing flange 21 is pivotally supported on the fulcrum shaft 20 installed on the engine section E side, and is suspended from the end of the square pipe 23 fixed to the outer surface of the Glen tank B. The provided fulcrum shaft 19 is fitted and pivotally supported by being fitted into a support metal 24 erected on the engine portion E, and the other end of the square pipe 23 is detachably attached to a cabin frame 25 via an opening / closing bolt 26. Configure.

Further, the bearing flange support member 3 which is provided continuously with the transfer cylinder 15a by pivotally supporting the start end of the transfer conveyor 15 is formed so that the tip end of the bearing flange 21 can be fitted thereto. Hooks capable of engaging with the supporting member 3 at the bearing flanges 21 are respectively formed at the ends of 1, 15 so as to engage with each other in the rotational direction when fitted. 29 is provided to support the bearing 30 projecting from the end of the Glen tank B by pivotally supporting the starting end side of the discharge conveyor 1. The support member 2 includes a rotatable lever 31 and a guide plate 32. The hook-shaped locking body 2a that can be opened and closed while being moved along the operation groove 32a is pivotally mounted 33 upward, and the diameter D _{2 of the} conveyor 15 is the grain at the joint between them. When the grains are clogged The configure in the diameter D ₁ larger diameter of the discharge conveyor 1 odd.

A load cell which is a strain gauge and serves as a sensor for displaying a weight between the support members 2 and 3, which are the parts to which the weight of the Glen tank B is mainly loaded, and the chassis 4a and 4b below the support members 2 and 3. 5a and 5b are respectively interposed, and the weight of the grain can be displayed in the cabin D by detecting both load cells 5a and 5b.

Therefore, during the combine operation, the weight of the grains put into the grain tank B can be detected by both load cells 5a and 5b below both sides of the grain tank B, and can be effectively measured at all times. Then, when the weight of the aircraft does not settle, the aircraft can be moved to discharge the grains in the Glen tank B, or the grains in the Glen tank B can be weighed and discharged as they are. , The hook 29 is removed, the lever 31 is moved from one side of the guide groove 32a to the other side, the locking body 2a is moved upward as shown by the phantom line in FIG. When the one end side is pulled outward, the bearing flange 21 and the clutch portion 27 are separated from the support member 3 and the clutch portion 28, and the bearing 30 is separated from the support member 2. On the other hand, the Glen tank B can be opened by rotating about the fulcrum shafts 19 and 20 as shown by arrow a.

[0011]

As described above, according to the present invention, the weight of the grain put into the grain tank B can be detected by the load cells 5a and 5b on both lower sides of the grain tank B during the combine operation. In the wetland, when the weight of the aircraft does not sink, the aircraft is moved to discharge the grains in Glen Tank B, or the grains in Glen Tank B are constantly measured. Therefore, it is possible to measure and discharge it as it is, and it has a feature that it can be suitably implemented with a simple structure.
