Abstract

PURPOSE:To prevent dropping and discharging of grain culms directly in an unbound state onto a recovery device by setting an interval between mounting positions of both sensors at a smaller value than conveying pitch of bound grain culms and notifying an abnormality only when both the sensors simultaneously sense and operate. CONSTITUTION:In a binder (B), when binding operation is normally performed, a buzzer 16 is not operated since both sensors (15a) and (15b) will not simultaneously sense. If a mistake in binding is caused and grain culms are conveyed in a loose state, an abnormality notifying means (E) is operated to know an abnormality by an operator before dropping the loose grain culms onto a recovery device.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention includes a binding device that intermittently ties harvested grain culms at predetermined intervals, and also lifts the tied grains rearward and upward. The present invention relates to a reaping and tying machine with a collecting device, which is equipped with a lifting and transporting device for transporting (2) dropping the device from its terminal end onto a collecting device for collection.

[Conventional technology]

In the reaping and tying machine with a collection device, conventionally, as disclosed in Japanese Patent Laid-Open No. 63-273408, a switch for detecting passage of grain bundles has been conventionally provided in the mid-transport part of the lifting and transporting device. There is a system that counts the number of bundled grain culms based on the detection result of this switch, and when the count reaches a set value, a buzzer sounds to notify the operator.

[Problem to be solved by the invention]

However, the structure of the above-mentioned example has the disadvantage that, for example, if a bundling failure occurs in the bundling device and the grains are supported and conveyed in a disjointed state, the proper number of bundles cannot be counted. The loading of grain bundles into the collection device was not carried out in an orderly manner, resulting in disordered postures, which caused problems in subsequent collection.

An object of the present invention is to prevent the above-mentioned problems from occurring by detecting an abnormality in the binding operation of a binding device during grain transportation, without making any major structural improvements.

[Means to solve the problem]

The features of the present invention are as follows: 1. In the collecting device cutter and tying machine, sensors are provided at two locations in the middle of the lifting and conveying device to detect the presence of grain at those positions, and both sensors are installed. The positional interval is set to be smaller than the conveyance pitch of the bundled grains that are intermittently conveyed from the binding device, and means is provided for notifying an abnormality only when both of the sensors are activated. There is, and its actions and effects are as follows.

[Function] In other words, when the binding operation of the grains by the binding device is performed normally, the bundled grains are transported with a predetermined conveyance pitch, so that both sensors simultaneously detect the existence of grains. It will not be detected.

If a bundling error occurs in the bundling device and grains are transported in a separate state without being bundled, grains will also exist in the middle of the transport pitch, so both sensors will detect the grains at the same time. The abnormality will then be notified.

〔Effect of the invention〕

Therefore, according to the present invention, if a bundling operation error occurs, the abnormality is notified during transportation by the lifting and conveying device, and the operator can confirm this and immediately take appropriate measures. This makes it possible to prevent unbound grains from falling onto the collecting device.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

FIGS. 3 and 4 show a reaping and tying machine with a collection device according to the present invention. This reaping and tying machine is equipped with a reaping pre-processing section (l) at the front of the machine body, a tying device (B) at the left rear of the reaping pre-processing section (l), and a driving section (1) at the right rear.

The reaping pre-processing section (l) includes a lifting device (2) that pulls up the fallen grain culm into a vertical position, a backer (3) that scrapes the raised grain to the rear of the center, and a lifting device (3) that pulls the grain culm that has been raised to a vertical position; A clipper-type reaping device (4) that cuts the grain, and a vertical conveyance device (5) that transports the harvested grain culm in a vertical position while gradually changing its position to a sideways position while conveying it backwards.
), etc., and the grains transported by the vertical conveyance device (5) are successively raked by the raking packer (6) in the bundling device (B) and bundled into a predetermined grain amount. In this state, it is tied with a binding string and discharged rearward and upward by a discharge arm (7).

As shown in FIGS. 1 and 2, the lifting and conveying device (
C) is installed in such a way that its conveyance path is connected to the release path from the binding device (B), and the chain case (8) is raised and extended diagonally rearward and upward from the rear position of the binding device (8). , Inside this engineering case (8), the drive block at the lower end! - (9) and the driven subrocket (10) at the upper end, a chain with protrusions (11) is wound around it.

The chain (
11) and exposed (7) chain (1
Clamping rails (12) are provided oppositely along the line 1). The exposed portion of the chain (11) is rotated upward to grip the grain bundle and lift and transport it upward.

At the upper end of the hoist conveyance device (C), after once receiving the conveyed grain bundles in a horizontal position, a collection device (
D) A receiving member (l3) to be dropped onto is provided.

The recovery device CD) is pivotally supported on the body so as to be swingable around a horizontal axis (P) at the rear lower end, and a hydraulic cylinder (14) is pivotally connected between the lower surface of the cargo platform and the body. It is configured so that it can be freely switched between a recovery operation position where it is stably mounted on the aircraft body and a recovery east release position where it is tilted upward.

And the lifting conveyor! (C) A pair of sensors (
15a) and (15b), and both sensors (
15a). (15b) is set to be smaller than the conveyance pitch (l) of the bundled grains that are intermittently conveyed from the binding device (B). In other words, as described above, the binding device (B) receives the grains fed in a separate state, quickly performs the binding operation after a predetermined amount has accumulated, and releases the bundled grains. The bundled grain culms are sent out intermittently at a predetermined conveyance pitch (1) at intervals of time until a predetermined amount of grain is accumulated.

Both sensors (15a). (15b) are attached so that the interval between the attachment positions is smaller than the conveyance pitch (l). Each of the sensors (15a), (15b)
are respectively set to cross the conveyance path (S) in the lifting conveyance device (C), and when the grain culm bundle passes therethrough, they swing into contact and are freely retracted out of the path (S); Moreover, it is configured to be biased to return to the set state.
