Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0023] According to Figure 1 , 2 , 3, 4, the embodiment proposes a scraper grain scooping-out mechanism for assisting in grain scooping-out, which comprises an inclined support frame 1 and a material guiding groove 6. The material guiding groove 6 is internally provided with a scraper conveyor. The inclined support frame 1 is arranged below the material guiding groove 6. One end of the inclined support frame 1 is fixedly provided with a material scooping groove 3. The material scooping groove 3 is provided at the upper end with a power bin 5. The material guiding groove 6 is in communication with the material scooping groove 3 through the power bin 5. The material scooping groove 3 is internally provided with a helical material feeding mechanism. The scraper conveyor comprises a scraper chain. The scraper chain is in a ring structure formed by a plurality of scrapers. The scraper chain is installed in the material guiding groove 6. A power driving part provides power for the circulating movement of the scraper chain. In operation, the power device 7, generally a motor, drives the scraper chain to move in the material guiding groove 6 in a circulating manner. The scraper conveyor moves in a reciprocating manner to scoop the grain from the material scooping groove 3 into the material guiding groove 6, and then sends the grain out of the material guiding groove 6.

[0024] The basket 8 is sleeved on the end of the material guide groove 6 away from the power bin 5, and is hingedly connected to the material guide groove 6 through a pivot 13 on the side close to the material guide groove 6. The pivot 13 is fixedly provided with a movable handle 14 on the lower end face on the side away from the material guide groove 6. The outer side of the material guide groove 6 is provided with an adjusting assembly for pushing the movable handle 14 to swing. The adjusting assembly is detachably connected to the material guide groove 6 and the movable handle 14.

[0025] The basket 8 arranged at the discharging end of the material guide groove 6 can limit the grain. The grain sprayed from the material guide groove 6 will accurately fall into the collecting device under the shielding of the basket 8, and will not splash outward. The angle of the basket 8 can be adjusted through the adjusting assembly, which has high flexibility. The adjusting assembly is fixed in a detachable manner, which is easy for the operator to maintain.

[0026] Regarding the spiral feeding mechanism:

[0027] The spiral feeding mechanism comprises a rotating shaft 9 and a feeding scraper. The rotating shaft 9 is rotatably connected to the inner side of the material scraping groove 3. Two groups of spiral blades 10 are fixedly connected to the outer side of the rotating shaft 9. The screw threads of the two groups of spiral blades 10 are opposite in direction. The feeding scraper is movably arranged on the outer side of the rotating shaft 9 through a chain structure. The two spiral blades 10 are arranged on the left and right sides of the feeding scraper. The outer side of the power bin 5 is provided with a power device 7 for controlling the rotation of the rotating shaft 9. Specifically, the power device 7 generally controls the rotation of the rotating shaft in the material guide groove 6 through a speed reducer. The rotating shaft drives the rotating shaft 9 to rotate through a sprocket and a chain. The scraper for scraping material is movably arranged on the sprocket. When the rotating shaft 9 rotates, the spiral blades 10 will converge the grain to the central area of the material scraping groove 3, i.e. the area where the scraper conveyor is located. The scraper conveyor and the power device 7 are both common technical means of the existing grain scraping machine, which will not be described in detail here.

[0028] It is worth noting that the pivot 13 is rotatably connected to the left and right sides of the material guide groove 6, and the pivot 13 is fixedly connected to the basket 8 on the side away from the material guide groove 6.

[0029] The basket 8 is rotatably connected to the material guide groove 6 through the pivot 13. In order to avoid the material guide groove 6 and the basket 8 from being in contact when the angle of the basket 8 is adjusted, a window allowing the basket 8 to rotate is formed on the side of the basket 8 close to the material guide groove 6. The material guide groove 6 passes through the window.

[0030] Regarding the adjusting assembly:

[0031] The adjusting assembly comprises two groups of electric push rods 11 arranged on the left and right sides of the material guide groove 6. The installation end of the electric push rod 11 is fixedly connected with an installation sleeve 12. The installation sleeve 12 is assembled with a fixing bolt which is threadedly connected with a bolt hole arranged on the outer side of the material guide groove 6. The power end of the electric push rod 11 is fixedly connected with a sliding block 15 which is slidingly connected with the movable handle 14. When the shielding angle of the basket frame 8 is adjusted, the two groups of electric push rods 11 simultaneously push the sliding block 15 from the left and right sides of the material guide groove 6. The sliding block 15 slides along the movable handle 14. The pivot 13 rotates counterclockwise. The basket frame 8 is lifted upward. Conversely, the sliding block 15 pulls the movable handle 14. The pivot 13 rotates counterclockwise. The basket frame 8 falls down.

[0032] More specifically, the movable handle 14 is arranged with a sliding groove 16 on the side away from the basket frame 8. The sliding block 15 is slidingly arranged in the sliding groove 16. A limiting rod 18 is fixedly arranged in the sliding groove 16. The limiting rod 18 penetrates the sliding block 15. The sliding block 15 is slidingly connected with the limiting rod 18. The sliding block 15 is sleeved on the outer side of the limiting rod 18. When the sliding block 15 slides along the sliding groove 16, the limiting rod 18 guides the sliding block 15 so that the sliding block 15 does not move sideways when sliding, improving the stability of the movable handle 14. After the fixation between the installation sleeve 12 and the material guide groove 6 is released, the sliding block 15 is slid along the limiting rod 18 and removed from the limiting rod 18. The electric push rod 11 can also be removed, which is convenient for replacement and maintenance.

[0033] In order to improve the stability of the sliding block 15 when sliding, in the preferred scheme, the left and right sides of the sliding block 15 are arranged with a guide groove 17 which is slidingly connected with a guide rib 19 arranged on the inner side of the sliding groove 16. The guide rib 19 is integrally formed with the movable handle 14. When the sliding block 15 slides along the sliding groove 16, the guide rib 19 on the inner side of the sliding groove 16 limits the sliding block 15 from the left and right sides of the sliding block 15, avoiding the upward and downward movement of the sliding block 15, and further improving the stability of the movable handle 14.

[0034] In order to facilitate the movement of the grain scraping mechanism, the front support wheel 2 is rotatably arranged at the lower end of the inclined support frame 1. The rear support wheel 4 is rotatably arranged at the lower end of the material scraping groove 3.

[0035] The working principle of the present application is as follows:

[0036] The scraper conveyor comprises a scraper chain which is connected by a plurality of scrapers in a ring structure and is installed in the guide chute 6, and a power driving part provides power for the circulating movement of the scraper chain. During operation, the power device 7 is generally a motor which drives the scraper chain to circulate in the chute through a speed reducer. The scraper conveyor carries the grain from the spading chute 3 to the guide chute 6 through reciprocating operation, and then sends it out of the guide chute 6. The basket 8 arranged at the discharge end of the guide chute 6 can limit the grain, and the grain sprayed from the guide chute 6 will accurately fall into the collecting device without splashing outwards under the shielding of the basket 8. The angle of the basket 8 can be adjusted through the adjusting assembly, which has high flexibility. The adjusting assembly is fixed in a detachable manner, which is easy for the operator to maintain.
