[0028] It needs to be explained that supporting frame is installed on robot body 1, storage cabin 2 is slidably connected with supporting frame, for storing sampled grain material, when storage cabin 2 is completely inserted into supporting frame and fixed, just make the material lifted by spiral material lifting piece 4 enter storage cabin 2.Elastic member 6 uses spring with high elastic coefficient, so that the bottom end of supporting block 7 can give supporting block 7 downward force when contacting with ground or grain material, so that supporting block 7 plays the role of support.

[0029] As Figures 1 to 5 As shown, spiral material lifting piece 4 includes: protection cylinder 8, movably arranged on fixed plate 3;Spiral shaft 9, rotatably arranged in protection cylinder 8;Spiral blade 10, installed on spiral shaft 9;Driving member 11, fixedly installed in protection cylinder 8 and used to drive spiral shaft 9 to rotate.Driving member 11 uses driving motor, driving member 11 is fixedly connected with protection cylinder 8 through baffle, and the rotating shaft of driving member 11 is fixedly connected with the top end of spiral shaft 9, which can ensure the normal rotation of spiral shaft 9 and prevent grain material from affecting driving member 11.

[0030] As Figures 1 to 5 As shown, it further includes: lifting member 12, installed on fixed plate 3, for changing the horizontal height of driving member 11, so that spiral shaft 9 and protection cylinder 8 extend out of robot body 1 and are inserted into grain, so as to realize material sampling.

[0031] It needs to be explained that lifting member 12 can adopt the structure of electric push rod or air cylinder.Lifting member 12 is connected with the top end of driving member 11, for changing the horizontal height of driving member 11, and driving spiral shaft 9 to rise or fall, when starting to work, lifting member 12 makes spiral shaft 9 and protection cylinder 8 extend out of robot body 1 by a distance, such as 8-12cm, and the optimal value is 10cm, so that lifting member 12 is inserted into grain material, at this time, driving member 11 starts to drive spiral shaft 9 to rotate, and grain material rotates with spiral shaft and cooperates with protection cylinder 8, to start lifting material into storage cabin 2.

[0032] Embodiment two: as Figure 3As shown, it also includes: the buffer groove 13, open at the bottom end of the spiral shaft 9, and is set to lift the spiral shaft 9 out of the protection cylinder 8, and the buffer groove 13 is used to accommodate the grain material.

[0033] It should be noted that the buffer groove 13 will enter a part of the grain material after the spiral shaft 9 is inserted into the grain material, and when the spiral lifting element 4 lifts the grain material, the area presents a downward concave condition, at this time, the grain material in the buffer groove 13 will continuously flow outward to supplement, so that the lifting of the material is more uniform, so that the robot body 1 is more stable during the sampling process; in addition, the buffer groove 13 is provided at the bottom end of the spiral shaft 9, which can reduce the weight of the robot body 1.

[0036] It should be noted that the support block 7 is trapezoidal in cross section, which can avoid the accumulation of grain material at the top end of the support block 7 during the movement of the robot body 1, and reduce the obstruction to the movement of the robot.

[0037] The bottom end of the support block 7 is installed with smooth material.

[0038] The support rod 5 and the support block 7 are made of light material.

[0039] It should be noted that since the bottom end of the support block 7 needs to be rubbed with the ground or grain material, the surface of the bottom end of the support block 7 needs to be made of smooth material, or smooth material is directly added to the bottom end of the support block 7. At the same time, since the overall weight of the robot body 1 needs to be controlled, the support rod 5 and the support block 7 need to be made of light material to prevent the robot body 1 from sinking into the accumulated grain material during movement or sampling. Therefore, the support rod 5 and the support block 7 are made of aluminum alloy, polytetrafluoroethylene or carbon fiber composite material to ensure the normal operation of the robot and the continuous development of the sampling work.

[0040] In the above scheme, each operation of the robot body 1 is a prior art, which is controlled by the existing control system, which is well known in the art, and the practitioners in the industry are familiar with it, which will not be repeated here.

[0043] The grain material lifted by the spiral lifting piece 12 is guided by the discharge pipe 14 installed on the side wall of the protection cylinder 8 during the lifting process, so that it enters the storage cabin 2 according to the predetermined path. At the same time, the storage cabin 2 is slidably connected to the support frame on the robot body 1, and as the material is continuously lifted and enters, the storage cabin 2 is gradually filled. When the storage cabin 2 is completely inserted into the support frame and fixed, the entire material lifted by the spiral material lifting piece 4 is smoothly entered into the storage cabin 2, and the collection of the material is completed.

[0044] During the lifting process of the spiral material lifting piece 4, when the bottom end of the supporting block 7 contacts the ground or the grain material, the supporting block 7 can effectively support the robot body 1 due to the high elastic coefficient of the elastic piece 6.
