Description

[Detailed explanation of the idea] The present invention relates to an improvement of a pulse threshing machine.

The present inventor previously proposed a granulation reel that was pivotally supported in the granulation chamber of the machine, a pair of feed rolls that were pivotally supported at the supply port of the granulation chamber so as to rotate with a difference in circumferential speed, and a rotation trajectory of the granulation reel. We have developed a pulse threshing machine featuring a threshing device consisting of a rotor guide fixed in the threshing chamber at a constant interval from the rotor guide.

However, with this product, the shedding action of hitting the legume pods is from the bottom to the top using the tooth rod of the threshing reel, and the pods are received by the rotor guide and reflected back and forth, vibrating back and forth. Grain shedding was not performed and the shedding accuracy was low. In addition, in this type of threshing machine, grain culms with bean pods are threshed in a throwing manner, so that it is difficult to smoothly discharge the grain culms that have been threshed into the rack.

The present invention was devised to solve the above-mentioned problems, and its primary purpose is to provide a new grain threshing machine that improves grain threshing accuracy. The second purpose is to provide a new pulverizer that can be used smoothly.

Hereinafter, the present invention will be explained in order according to an embodiment illustrating the present invention. In FIG. A pair of feed rolls 4 and 5 are rotatably supported at the supply port 20 of the chamber 2 so as to rotate with a circumferential speed difference, and a pair of feed rolls 4 and 5 are rotatably supported at the supply port 20 of the chamber 2, and the granulating reel 3 is placed at a constant distance D from the rotation locus W of the granulating reel 3 in the granulating chamber 2. It consists of a rotor guide 6, etc. installed in the rotor guide 6. 21 is a hopper, and 22 is a grain board.

The threshing reel 3 is assembled into a basket shape as shown in FIG. 3 by arranging a plurality of toothed rods 30, 30... parallel to the feed rolls 4, 5 in parallel around a rotating shaft 31. Comb teeth 32, 32, . . . projecting radially outward from the rotation locus W are provided between the toothed rods 30, 30, . 3
Reference numeral 3 designates a cross-shaped support member that is fixed to a plurality of locations on the rotating shaft 31 at regular intervals and horizontally supports the tooth rods 30, 30, . . . in a cage-like manner.

The comb teeth 32 are provided so as to be located at the tips of arms 34 that branch out from each of these support members 33, and the comb teeth 32 are provided so as to be located at the tips of arms 34 that branch out from each of these support members 33, and within the range of the distance D between the tangent to the rotation trajectory W and the rotor guide 6, protrudes radially outward from the By the comb teeth 32, the capsule H
It is designed to give vibration in the left and right direction.

35 is a feed plate horizontally fixed to each of the arms 34 within the rotation locus W of the tooth rod 30. The grain culm S after being subjected to the shedding action by the feeding plate 35
It has been designed to have an evacuation effect on, etc.

The pair of feed rolls 4 and 5 are set so that the circumferential speed of the lower feed roll 5 is faster than the circumferential speed of the upper feed roll 4.

The rotor guide 6 is provided in the vicinity of the upper feed roll 4 at a distance D from the tangent to the rotation locus W, and is configured so that the shell H is slammed against the guide surface by a toothed rod 30. I'm getting cozy.

In FIGS. 1 and 2, a 70 is used to remove the bean grains G, which have been threshed by the above-mentioned threshing device a, and crushed waste such as grain culms S and husks H, to the front of the machine body 1 (the left side in FIG. 1). 71 is a swinging sorting shelf located below the threshing chamber 2 and supported to swing back and forth in the inner cavity of the machine body 1 in order to sort the grains while transferring them to This is a transfer shelf supported so as to swing back and forth below the swing sorting shelf 70 so as to receive the beans G leaking from the sieve mesh and transfer them to the front of the machine body 1. In FIG. 1, 72 is a sorting belt disposed in front of the transfer shelf 71 in the transfer direction (in the direction of the arrow in FIG. 1), 73 is a china blower, 74 is a sorting air path, and 75 is a sorting belt for the sorted beans G. A screw conveyor 76 for taking out is an outlet for discharging the grain culm S from which the beans G have fallen off, crushed waste, etc.

Next, to explain the main function of the pulverizer A configured as described above, the hopper 21 is connected to the supply port 20
As shown in FIG. 2, the grain culm S is sandwiched between upper and lower feed rolls 4 and 5, and the husks H are crushed and divided while being sent into the threshing chamber 2. be included. At this time, the upper and lower feed rolls 4, 5 are in an upward position on the sending side due to the peripheral speed, and the tooth rods 30, 30... It acts like hitting from the bottom to the top, and therefore, the grain culms S, etc. that are thrown out from the rotation trajectory W are received by the rotor guide 6, reflected, and pushed back toward the rotation trajectory W side again. receive vibrations. On the other hand, the comb teeth 32, 32...
The object is bounced to the left or right and receives left and right vibrations.

In this way, the grain culm S, etc. sent into the threshing chamber 2 is subjected to back-and-forth and left-right vibrations, and is shattered, and the empty culm, empty husks, crushed waste, etc. tend to stay on the flow grain plate 22. However, a feed plate 35 horizontally fixed to the arm 34 forcibly transfers the crushed debris and the like to the base end side of the swing sorting shelf 70.

As mentioned above, in this invention, the first
A granulation reel that is pivotally supported within the granulation chamber of the machine body, a pair of feed rolls that are pivotally supported at the supply port of the granulation chamber so as to rotate with a difference in circumferential speed, and a granulation reel located at a fixed interval from the rotation locus of the granulation reel. In a granulating device consisting of a rotor guide provided in the granulating chamber, the granulating reel is assembled into a basket shape by arranging a plurality of toothed rods parallel to the feed roll around a rotation axis parallel to the toothed rods. In addition, the tooth rods are provided with comb teeth that protrude radially outward from the rotation locus, so that in addition to vibrations only in the front and back directions of conventional grain threshing equipment, vibrations in the left and right directions are repeatedly applied. As a result, a high level of grain shedding performance is exhibited.
