Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a grain bagging device, more specifically, a support rod for suspending the opening of the bag, and a pedestal for receiving the bottom of the bag, which are provided below the grain tank. Regarding the bagging device installed in 〇-ff, in the combine harvester l, the husks harvested in the harvesting section are threshed by the threshing section, and the threshed grains are stored on the side of the threshing section. fed to the grain tank,
The grains are packed into grain bags from the tank. Therefore, the grain bagging operation is carried out by suspending both upper sides of the grain bag from support rods provided below the tank, so that the opening of the bag faces the supply port of the tank, and This is done by placing the bottom part on a pedestal below the support rod. By the way, the work of the harvester is often performed by one operator, for example, the steering operation of the combine harvester and the bagging work are performed by one operator. Therefore, in order to take out the grains from the grain tank, After the grain bag supported by the support rod faces the supply port of the grain tank,
The operator returns to the driver's seat and steers the combine harvester, and the grain bagging work is performed automatically. If the bottom of the grain bag is bent, it may not be possible to effectively fill the grain bag with a predetermined amount of grain by simply charging the grain from the tank. It was not possible to fill the specified amount of grains. Therefore, in the past, for example, as shown in Japanese Utility Model Application Publication No. 52-8086, a vibrating body is provided on a pedestal that receives the bottom of the grain bag, and the vibrating body ≦ the bottom of the grain bag is pushed up and vibrated. A bagging device was proposed in which the bag was forcibly filled with grains, but in such a bagging device, unless the amplitude of the vibrating body was increased, the vibration of the vibrating body would reach the top of the bag. If the information is not communicated to the post office, a reliable bagging effect cannot be expected. By the way, when increasing the amplitude of the vibrating body in order to apply specified vibration to the top of the bag, there is a risk of giving a large shock to the support rod and causing damage, and furthermore, the bottom of the grain bag may be bent. In such cases, the grain could not be packed reliably and effectively due to the inability to deal with the situation. Furthermore, in the bagging device, it is necessary to push the bottom of the grain bag upwards using a vibrating body.In other words, it is necessary to push up the heavy bag containing grains about 6 times in total, which results in power loss. is large. However, in order to solve the various problems mentioned above, a system was developed in which the support rod of the grain bag is swung vertically via a swinging device, and vibration is applied to the entire bag stack from the upper side. I first proposed this and applied. By the way, when this bagging equipment is used to bag grains,
If the support rod is constantly oscillated, not only will there be a large power loss, but the oscillation device will deteriorate prematurely. The present invention was made based on the above considerations, and its purpose is to remove the bag number from the grain tank when the grain bags are filled with grains during grain bagging work. Taking advantage of the fact that the grains remain in the tank without being drained, the stagnation of the grains is detected and the support rod is oscillated for a certain period of time or by a certain number of 1gT, thereby temporarily controlling the support rod. The aim is to reliably and efficiently fill a grain bag with a predetermined amount of grain even when the grain bag is oscillated. However, in the configuration of the present invention, near the supply port of the grain tank,
In addition to providing a sensor to detect stagnation of grains, the support rod of one grain bag is swingably supported and linked to a swinging device, and the swinging device is actuated by the operation of the sensor. The grain bagging apparatus according to the present invention will be explained below with reference to the embodiments shown in the drawings. In the figure, (1) is a grain tank having a lower g&co supply port [1a] provided on the side of the threshing part (D) of the combine harvester l, and the tank (1) and the threshing part (D) ) between
A grain frying thrower (S) is interposed so that the grains threshed by the threshing dls (D) are fed into the tank (1) through the thrower (S). A pair of support rods (2) extending outward from the threshing section CD are located below the supply 0 (1a) in the tank (1J).
At the same time, a pedestal [6] extending from the threshing m (D) side is provided at the lower end of the support rod (2). In this way, both sides of the upper end of the grain bag (4) are suspended from each of the support rods (2), and the opening of the bag (4) is made to face the supply port (1a) of the tank [1]. The bottom of the bag [4] is placed on the pedestal (6), and grains are loaded from the tank (1) into the grain bag (4). In this case, a sensor (5) for detecting grain stagnation is provided inside the tank (1) near the supply port (1al), and a sensor (5) for detecting grain stagnation is provided inside the tank (1). (2) is supported in the threshing section (D) III!l so as to be able to swing up and down, and is linked to the swinging device (6), while this swinging device (6) is activated by the operation of the sensor (5).

The eccentric rotation of the support rods [2] causes the support rods [2] to swing up and down via the rods (15) and swing links (11). This special code for the outflow of grains in the tank [1] uses a pressure-sensitive sensor (5) that does not operate but operates when the grains are stagnant in the tank (1), and this sensor (

), when the grain bag (4) is filled with grains close to the opening and the grains are stagnant in the tank (1), the sensor [5] turns on. The motor (lp'r) is driven to rotate for a certain period of time to vertically swing each of the support rods (2), giving vibration to the grain bag (4) supported by each of the support rods (2). The inner number of the bag (4) is filled with a predetermined amount of grains.In the embodiment shown in the figure, a reversible motor (16) is operated to open and close the supply port (1a) of the tank (1). A shutter [17] is provided, and the opening/closing operation of the shutter (17) and the swinging operation of each support rod (2) are electrically controlled.

As explained above, in the bagging device of the present invention, a sensor for detecting stagnation of grain is provided near the supply port of the grain tank, and the supporting rod of the grain bag can be swung. The oscillating device is operated by the operation of the sensor while the oscillating device is operated by the operation of the sensor. 1. During the bagging operation of grains, the grain bags are filled with grains up to the vicinity of the opening. When grains stagnate in the tank without flowing out from the grain tank into the bag, this stagnation of grains is detected by the sensor, and the support is moved through the rocking device. Since the rod is oscillated to give vibration to the bag, it is possible to reliably fill the grain bag with a predetermined amount of grain. Since this process is carried out over a certain period of time when the grains are filled almost to the top, it has become possible to efficiently fill the grains without causing power loss.
