Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a stationary threshing device and a threshing device that can be mounted on a combine, a harvester and the like, and more specifically, a threshing unit and a sorting unit can be divided into two parts. The present invention relates to a threshing device that can be exchangeably connected with a separation position as a boundary.

[Prior art]

In a conventional combine harvester, a threshing device on one side of the machine body, an engine on the front side of the machine body and the like, and a Glen tank on the rear side are arranged in series above a machine body frame provided in a horizontal direction. Further, a pair of left and right crawlers are arranged on the lower side of the machine body frame, and a pretreatment section including a card raising section, a cutting blade, and a conveying section is arranged in front of the machine body frame. There is.

The most problematic issue with the above-mentioned combine with a Glen tank is the left-right balance of the aircraft that differs when the specified amount of grains is stored in the Glen tank and when the Glen tank becomes empty. Especially in a wetland where crawlers tend to sink, if a certain amount of grain is stored in a grain tank that is unevenly distributed on one side of the aircraft, the left-right balance of the aircraft will be lost, and the aircraft will tilt significantly toward the Glentank. There was a problem that the mowing work by the department became impossible.

To solve this problem, Japanese Utility Model Laid-Open No. 55-14428 or Japanese Patent Laid-Open No. 59-224621 has been proposed. All of these have a structure in which a grain tank is arranged in a space generated between crawlers provided on both left and right sides, and a thresher is mounted above the grain tank. The grain tank from the threshing device is stored in the Glen tank located in the center of the width of the machine to maintain the left-right balance of the machine.

[Problems to be solved by the invention]

By the way, the prior art described in the above-mentioned publication is a so-called two-story structure in which the threshing device mounted above the Glen tank is provided with the threshing unit above the sorting unit, and the threshing device above the Glen tank is above ground level. And the whole machine becomes unstable, and it becomes difficult to maintain and inspect the sorting section located below the threshing section, and at the same time, the sorting section and the threshing section cannot be separated and exchanged, and rice and wheat Even if threshing / sorting can be performed by the same threshing device, there is a drawback that the sorting unit and the threshing unit cannot be easily exchanged for threshing / sorting soybeans, buckwheat, etc. other than rice.

Therefore, in view of the above-mentioned conventional circumstances, the present invention was devised to solve those problems, and a first object thereof is to provide a threshing device capable of separating and exchanging a threshing unit and a sorting unit, The second purpose is to provide a threshing device in which the threshing unit and the sorting unit can be separated and replaced by using a Glen tank.

[Means for solving problems]

According to a first aspect of the present invention, a threshing unit for threshing a grain culm sandwiched between a feed chain and a picking rail, and a sorting unit for sorting grains to be shredded from the threshing unit are provided between the two units. Exchangeable with the intervening separation position as a boundary, and
In addition to being arranged in series in the front-rear direction, a transporting section for transferring the grains to be shredded from the threshing section to the sorting section is arranged in series with the threshing section.

A second invention according to the present invention is to provide a box-shaped Glen tank having a width extending over the crawlers above the crawlers provided on the left and right sides and to mount the Glen tank above the Glen tanks. The threshing device is composed of a threshing unit for threshing the grain culms sandwiched between the feed chain and the sandwiching rail, and a sorting unit for sorting the grains to be shredded from the threshing unit, and the threshing unit and the sorting unit. Are interchangeable with the separation position interposed therebetween as a boundary, and are arranged in series in the front-rear direction.

[Action]

In this way, the threshing unit for threshing the grain culms sandwiched between the feed chain and the sandwiching rail, and the sorting unit for sorting the grains to be shredded from the threshing unit are separated by the separating position between the two. As replaceable, and arranged so as to be in series in the front-rear direction, by arranging a conveyor section for transferring the grains to be shredded from the threshing section to the sorting section in series with respect to the threshing section, The threshing section 4 and the sorting section 5 can be exchanged with each other depending on the material to be threshed.

In other words, in the case of rice or wheat that is difficult to shatter, the threshing section 4 having a normal handling room 20 in which a large number of handling teeth 19 are planted in the handling cylinder 17 is replaced, but soybeans that are relatively easy to shatter. In the case of buckwheat, etc., it is possible to treat materials that are difficult to shed by replacing them with a threshing section that has a handling cylinder with spiral handling teeth and a meshing mesh with a large mesh size. Damage to the grain due to excessive excessive threshing can be prevented.

Further, in the case of wheat, soybean, etc., in which a relatively long stalk breakage occurs frequently, by replacing the swing transfer sorting plate with a sorting unit arranged in, for example, three stages, the grain port 43 , It is possible to prevent stalk debris from being mixed in the second crop reduction gutter 56, but in the case of rice or buckwheat etc. in which relatively short stalk debris is often generated, the swing transfer sorting plates 35, 40 are 2 By exchanging the sorting unit 5 of a normal type arranged in stages, wind sorting using the sorting space can be efficiently performed.

The threshing section that processes soybeans, buckwheat, etc.
Since the clamping force between the stalk and the pinching rail 29 is set to be weak and the whole culm is put into the handling chamber 20, the straw conveyor belt 31 provided in the sorting section 5 or the straw conveyor section such as the straw conveyor chain. Can be omitted, and the cutter portion 33 can also be omitted.

Further, since the threshing unit 4 and the sorting unit 5 can be easily separated in the front-back direction with the separation position 6 as a boundary, and the sorting unit 5 is disposed behind the threshing unit 4, the sorting unit 4 is particularly preferable. Easy internal inspection and maintenance.

Further, above the crawlers provided on the left and right, a grain tank configured in the shape of a box having a width extending over the crawlers is provided, and a threshing device mounted above the grain tank is provided.
It is composed of a threshing unit for threshing the grain culms sandwiched between the feed chain and the picking rail, and a sorting unit for sorting the grain to be shredded from the threshing unit, and the threshing unit and the sorting unit are interposed therebetween. By disposing them so that they can be exchanged with the separation position as a boundary and arranged in series in the front-rear direction, there is no loss of left-right balance between when the grains are stored in the Glen tank 2 and when they are emptied. Therefore, the left-right balance of the machine body is maintained well, and the work performance of the combine in the wetland can be improved, but the threshing unit 4 and the sorting unit 5 that configure the threshing device 3 are arranged in series in the front-rear direction. Therefore, the ground height of the threshing device 3 can be lowered to maintain the stability of the machine body.

Since the sorting unit 5 has the first grain return plate 41 connected to the first grain port 43 of the Glen tank 2 located below, the lifting unit for connecting to the Glen tank for each sorting unit to be replaced. There is no need to provide a grain part, and replacement can be performed very easily.
