Example Embodiment

[0063] Example 1

[0064] A corn stalk husk separation device includes an axial flow drum and a screen. The screen e is arranged below the drum d along the length of the axial flow drum d. There is a gap between the drum and the screen, and the gap forms a straw separation space. Such as Picture 9 Shown. The spiral deflector 17 on the harvesting frame 11 and the inner surface of the screen e form a substantially cylindrical tube concentric with the axial flow drum d, and a straw separation space is formed between the cylindrical tube and the outer surface of the axial flow drum d. The sieve is a semicircular grid-like frame structure, and the grid-like frame composed of holes is 3cm×3.4cm long holes, which is suitable for the fall of irregular lump flesh and small flaky leaves. Such as Figure 6a with 6b Shown. There is a gap of 5mm between the drum and the screen. The axial flow drum includes a supporting disc A1, a toothed rod A2 and spike teeth A3. The toothed rod A2 is a ...

Example Embodiment

[0072] Example 2

[0073] Others are the same as in Example 1, the difference is:

[0074] The rack A2 is a long round tube, and the gap between the drum and the screen is 10mm.

[0075] The corn stalk husk separation device also includes an anti-blocking device, which is composed of a cleaning drum and a rotating shaft a1. The cleaning drum is composed of a sleeve a2 and round steel teeth a3 distributed on the circumference of the sleeve. The shaft is connected by a set screw a4. Such as Figure 7 Shown. The anti-blocking device is installed in the gap below the screen. Such as figure 2 with Figure 8 Shown.

[0076] If the leaves and flesh of the straw are damp, the irregular lump flesh and small pieces of leaves produced by the straw under the action of the drum and sieve may stick to the inner wall of the harvester after leaking through the sieve. The accumulation of sieve will block the sieve holes, resulting in weakening of the separation effect of straw. Therefore, the ant...

Example Embodiment

[0083] Example 3

[0084] Others are the same as Embodiment 1 or 2, the difference is:

[0085] There is a gap of 15mm between the drum and the screen.

[0086] The corn stalk husk separation device also includes a straw husk dispersion device, which is installed at the exit of the harvester by bolt connection. The straw husk dispersion device is composed of a shell b1, a rotating shaft b3 and a dispersing leaf b2, and a rotating shaft b3 And the dispersing blades b2 are installed in the housing b1; a sleeve is installed on the rotating shaft, and the dispersing blades are evenly distributed on the sleeve. Such as Figure 8 Shown. The sleeve and the rotating shaft are connected by a key, and other connection methods can also be adopted.

[0087] The method for separating corn stalk skin and flesh includes the following steps:

[0088] 1) The harvested corn stalks enter the drum;

[0089] 2) The drum rotates at a high speed, and the drum speed is 900r / min. With the cooperation of the s...

Abstract

The invention relates to an axial flow roller for separating skin and pulp of a straw and a separation device with the axial flow roller and belongs to the field of agricultural machinery. The device for separating the skin and the pulp of the straw comprises the axial flow roller and a screen, the axial flow roller comprises a round supporting disc, rack bars and spike teeth, the rack bars are fixed on the circumference outside the round supporting disc, and the spike teeth are fixed on the rack bars; the screen is arranged below the roller along the length of the axial flow roller, and a gap is reserved between the roller and the screen and forms straw separation space. The device for separating the skin and the pulp of the corn straw can be directly installed on a harvester so that when corn is harvested, simultaneously, the corn straw can be separated into elongated straw outer skin, irregular block pulp and small sheet leaf blades to be discharged, the elongated straw outer skin, the irregular block pulp and the small sheet leaf blades are dried and classified to be used, and utilization values of the straw are improved.

Description

technical field [0001] The invention relates to an axial flow drum for separating straw husks, a separation device including the axial flow drum, and a method for separating straw husks using the separation device for straw husk separation, belonging to the field of agricultural machinery. Background technique [0002] The current corn harvester adopts the method of crushing corn stalks and returning them to the field, which is used as fertilizer after crushing. However, corn stalks are divided into several parts: straw skin, pulp, and leaves. Among them, the pulp and leaves can be used as land fertilizer after decay. The main component of the outer husk is fiber, which takes a long time to rot and cannot improve the soil. After the corn stalks are crushed and returned to the field, the soil is easy to swell and reduce the water storage capacity of the soil. Underused. Corn stalks can be used as raw materials for papermaking. If the husk, pulp and leaves of corn stalks are ...
