[0002] At present, the whole amount of straw is required to be returned to the field in the rice-wheat rotation system in the Yangtze River Delta region. At the present stage, the straw is not treated by related disinfection, inactivation modification, etc. when the whole amount of straw is returned to the field, which leads to the difficulty of straw decomposition, and the intensification of diseases and pests. The grass seeds, pathogenic bacteria and insect eggs attached to the straw will directly enter the soil with the straw, and the accumulation of reducing substances and the increase of diseases and pests under the condition of flooding will further affect the growth of crops in the later period and cause environmental negative effects. Therefore, it is necessary to inactivate and modify the straw by using a machine.

The sterilization mechanism irradiates the straw by means of an ultraviolet lamp to achieve the effect of sterilization. However, the sterilization effect is particularly limited in actual use. On the one hand, it is difficult to achieve the sterilization effect due to the insufficient irradiation time. On the other hand, the straw is mutually shielded, and it is difficult to effectively achieve the sterilization effect. In addition, the design of the conveying mechanism is not reasonable enough to effectively gather the straw and pass through the sterilization mechanism. SUMMARY

DETAILED DESCRIPTION

[0027] The application will be further described below in combination with the drawings.

[0028] As Figure 1The shown harmful organism high-temperature inactivation device acting on field straw comprises a mobile base 10, a picking mechanism 1, a conveying mechanism 2 and a high-temperature inactivation mechanism 3 installed on the mobile base 10; the picking mechanism 1 is used for picking up broken straw; the high-temperature inactivation mechanism 3 has a long-strip-shaped inactivation chamber 31 extending forward and backward, and further comprises a hot air blower 32 for feeding hot air into the inactivation chamber 31; the inactivation chamber 31 has a straw inlet 31a at the front side and a straw outlet 31b at the rear side; the conveying mechanism 2 comprises a reciprocating pusher 21 capable of pushing straw towards the straw inlet 31a.

[0029] As shown in the drawings, Figures 2-3 The above-mentioned inactivation chamber 31 is composed of a conveying plate chain 31c and a U-shaped cover 31d inverted on the conveying plate chain 31c; the conveying plate chain 31c is composed of two parallel installed chain assemblies 311 and a plate body 312 across the two chain assemblies 311, and the plate body 312 on the upper conveying section of the chain assembly 311 forms a relatively complete bottom plate, which surrounds a square pipeline with the U-shaped cover 31d, and since the conveying plate chain 31c can play a conveying role, it can drive the straw to move backward.

[0030] A plurality of hot air blowers 32 are installed on the U-shaped cover 31d, and all the hot air blowers 32 are arranged in the front-rear direction. Specifically, the hot air blower 32 is placed on a mounting seat 33 fixed relative to the U-shaped cover 31d, and the air outlet of the hot air blower 32 is connected with the inactivation chamber 31 through a pipeline.

[0031] The high-temperature inactivation device is used after the agricultural machinery performs the broken straw harvesting operation, and is aimed at broken straw for post-processing. During the action process, the picking mechanism 1 picks up the broken straw, which is conveyed by the conveying mechanism 2 and pushed into the straw inlet 31a by the pusher 21. The reciprocating frequency of the pusher 21 is high, while the linear speed of the chain assembly 311 is slow. The reciprocating movement of the pusher 21 not only pushes the straw into the inactivation chamber 31, but also compacts the fluffy straw, thereby improving the density of the straw in the inactivation chamber 31, so that more straw can be inactivated at the same time. After the straw enters the inactivation chamber 31, the hot air blower 32 continuously injects hot gas into the inactivation chamber 31 to keep the inactivation chamber 31 in a high-temperature state. The high temperature can kill harmful living things such as grass seeds, pathogenic bacteria and insect eggs in the straw. The length of the inactivation chamber 31 is relatively long, and the straw can stay in the inactivation chamber 31 for a long time to kill harmful living things and achieve better inactivation effect.

[0032] A plurality of hot air blowers 32 are installed on the U-shaped cover 31d, which can make the heat in the inactivation chamber 31 more evenly distributed, and the straw can continuously be affected by high temperature when moving in the inactivation chamber 31, so as to improve the inactivation effect.

[0033] As Figure 5 shown, the edge of the pusher body 21 is mounted with transverse rollers 24 and longitudinal rollers 25, and the moving base 10 is mounted with guide tracks 26 for cooperating with the transverse rollers 24 and the longitudinal rollers 25, so that the pusher body 21 can move back and forth more smoothly. The pusher body 21 is driven by a crank 27, and a connecting rod 28 is connected between the crank 27 and the pusher body 21, and the connecting rod 28 is rotatably connected with the crank 27 and the pusher body 21, so that the crank 27, the connecting rod 28 and the pusher body 21 constitute a crank slider mechanism.

[0034] According to the above-mentioned high-temperature inactivation device for harmful organisms acting on field straws, the working width of the pickup mechanism 1 is greater than the width of the inactivation chamber 31; the conveying mechanism 2 includes a gathering assembly 22 for gathering the straws picked up by the pickup mechanism 1 to the middle; the pusher body 21 is located on the upper side of the middle part of the gathering assembly 22, and the conveying mechanism 2 further includes a pushing assembly 23 for conveying the straws from the gathering assembly 22 to the straw inlet 31a.

[0035] Since the working width of the pickup mechanism 1 is greater than the width of the inactivation chamber 31, on the one hand, the inactivation operation is performed on the straws in a very wide width range, and on the other hand, the inactivation operation is performed after the picked-up straws are gathered to the middle, which can reduce the width of the inactivation chamber 31, so that the heat is more easily concentrated to form high temperature, and the inactivation chamber 31 cannot concentrate heat and kill harmful living things due to the too wide width.

[0036] As Figure 4 , 5 shown, the pushing assembly 23 includes a pushing knife group 23a, an outer grass baffle 23b and an inner grass baffle 23c; the pushing knife group 23a includes a plurality of pushing knives arranged in a straight line array; the outer grass baffle 23b and the inner grass baffle 23c are both in a bent shape, and a curved channel extending rearward and upward is formed between the two; the central axis of the pushing knife group 23a is located on the inner side of the inner grass baffle 23c, and a plurality of accommodation grooves for the movement of the pushing knives are formed on the inner grass baffle 23c.

[0037] The above-mentioned gathering assembly 22 includes a conveying groove 22a, conveying augers 22b are rotatably installed at both ends of the conveying groove 22a, and the pushing assembly 23 is located in the middle part of the conveying groove 22a. When the machine tool operates, the conveying augers 22b at both ends will convey the materials to the middle, so that the straws picked up by the pickup mechanism 1 are gathered to the working range of the pushing assembly 23, and then the pushing assembly 23 operates to convey the straws in the conveying groove 22a from the bottom to the top to the working range of the pusher body 21.

[0038] When the conveying assembly 23 is in operation, the conveying blade group 23a reciprocates, and the pushing body 21 moves between two limit positions. When the pushing body 21 is at the front limit position, it is located in front of the arc-shaped channel outlet. The pushing body 21 and the conveying blade group 23a move in coordination. When the pushing body 21 is at the front limit position, the conveying blade group 23a swings to its highest point, pushing the straw to the rear of the pushing body 21. Thus, the pushing body 21 moves backward to push the straw in the middle of the conveying trough 22a along the curved channel to the rear of the pushing body 21, and then pushes the straw into the inactivation chamber 31. The conveying blade group 23a can move intermittently. It can stay at the highest position for a period of time so that the pushing body 21 pushes away the straw on the conveying blade group 23a before the conveying blade group 23a swings back to start the next round of conveying operation.

[0039] In addition, such as Figure 6 As shown, a first blade 29 is installed on the lower side of the rear end of the pusher body 21, and a second blade 210 is installed on the front side of the straw inlet 31a. Thus, when the pusher body 21 moves backward, the first blade 29 and the second blade 210 can cut the straw located at the lower edge of the pusher body 21 to prevent the straw from obstructing the movement of the pusher body 21.

[0040] The picking mechanism 1 includes a picking wheel 11 and a weed-blocking rod group 12; the picking wheel 11 has multiple picking rod groups 11a arranged in a circular array. When the picking wheel 11 rotates, the picking rod group 11a pushes the straw backward and upward, and the weed-blocking rod group 12 unloads the straw on the picking rod group 11a into the conveying trough 22a.

[0041] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
