Description

Technical Field

[0001] This invention relates to the field of sampling robot technology, and more specifically, to a multi-angle rotating robot capable of selective sampling. Background Technology

[0002] my country produces hundreds of millions of tons of grain every year, with a large proportion being stored grain. The storage environment and conditions determine the quality of the grain, directly affecting its shelf life and edible value. As a living substance, grain's respiration has a significant impact on its quality, and this respiration largely depends on the temperature and humidity of the storage environment.

[0003] In existing technologies, grain silos typically store large quantities of grain, often irregularly piled with varying heights, posing challenges to operation and sampling. Furthermore, the internal space of grain silos is usually limited, especially in areas with concentrated grain, where the operating space can be cramped or complex. Traditional grain silo robots, with their fixed motion patterns and working ranges, cannot effectively adapt to the irregular spatial layout and complex stacking conditions within grain silos for mobile collection, sampling, and detection. This results in some grains remaining undetected, affecting the accuracy of the detection. Therefore, inventing a multi-angle rotating robot capable of selective sampling to address these issues has become a pressing problem for those skilled in the art. Summary of the Invention

[0004] To overcome the above shortcomings, this invention provides a multi-angle rotating robot capable of selective sampling, aiming to solve the problem that traditional barn robots cannot effectively adapt to the irregular spatial layout and complex stacking conditions inside barns for mobile collection, sampling, and detection.

[0005] This invention is implemented as follows:

[0006] This invention provides a multi-angle rotating robot capable of screening and sampling, comprising multiple snake-shaped main bodies and connecting blocks and drive sleeves disposed on both sides of the snake-shaped main bodies. The three snake-shaped main bodies are welded and fixed to each other on their sides. A first limiting groove is provided at one end of each snake-shaped main body near both sides. A mounting base is installed on one side of each snake-shaped main body. A temperature and humidity sensor, an orientation sensor, and a pressure sensor are respectively installed on the three mounting bases.

[0007] The two connecting blocks are respectively installed at one end of the two serpentine bodies. A first limiting ring is installed at one end of the connecting block and is rotatably connected to the inner wall of the first limiting groove. A second limiting ring is installed at one end of the connecting block.

[0008] Two drive sleeves are respectively installed at one end of two connecting blocks. A partition is installed on the inner wall of one end of the drive sleeve. A second limiting groove is opened on one side of the drive sleeve and rotates to connect with the outer wall of the second limiting ring. A screw conveyor blade is installed on the outer side of the drive sleeve. A fixing port is opened at one end of the drive sleeve. A replaceable conical head and sampling assembly are installed on the inner wall of the fixing port.

[0009] Preferably, the front view of the serpentine body is an isosceles trapezoid, the front view of the connecting block is a right trapezoid, and one end of the driving sleeve is a frustum-shaped sleeve.

[0010] Preferably, a first internal gear ring is installed on the inner wall of the two serpentine bodies near the sides, and a first mounting groove is opened on the side of the connecting block near the serpentine body. A first motor is installed on the inner wall of the first mounting groove, and a first gear that meshes with the first internal gear ring is installed at the output end of the first motor.

[0011] Preferably, the connecting block has a second mounting groove on the side near the drive sleeve, a second motor is mounted on the inner wall of the second mounting groove, a second gear is mounted on the output end of the second motor, and a second internal gear ring that meshes with the second gear is mounted on the inner wall of one end of the drive sleeve.

[0012] By adopting the above technical solution, multiple snake-shaped main bodies, connecting blocks, and drive sleeves are combined to form a robot. By driving the motors, the angles of the drive sleeves at both ends are controlled, thereby realizing multi-angle rotation of the robot. The robot's direction of movement can be quickly changed as needed.

[0013] Preferably, one end of the conical head is threaded to the inner wall of the fixing port, and the temperature and humidity sensor, orientation sensor, pressure sensor and mounting base are all installed and fixed by threads.

[0014] By adopting the above technical solution, different detection devices are installed on multiple snake-shaped bodies. The position of the machine is determined by the orientation sensor, which makes it easy to adjust the machine to reach the target point in time. The temperature and humidity sensor detects the temperature and humidity in the barn, which helps the manager to more accurately grasp the environmental changes in the barn. The pressure sensor detects the pressure changes of the robot during the descent process, which avoids damage caused by excessive pressure.

[0015] Preferably, the sampling component includes a fixed sleeve and an adjusting sleeve, wherein the outer wall of the fixed sleeve and the inner wall of the fixed opening are threadedly connected.

[0016] Preferably, a third motor is installed on the inner wall of the fixed sleeve, the output shaft of the third motor is fixedly connected to the inner wall of the adjusting sleeve near the center, and the inner wall of the adjusting sleeve is rotatably connected to the outer wall of the fixed sleeve.

[0017] Preferably, the surface of the fixed sleeve is provided with a plurality of sieve holes of different diameters, and the surface of the adjusting sleeve is provided with a feed hole, the inner diameter of which is the same as the inner diameter of a sieve hole with the largest diameter.

[0018] Preferably, the feed hole is a frustum-shaped hole, the fixing sleeve has multiple adjustment grooves near the outer wall of the screen hole, the inner wall of the adjustment groove has a receiving groove, the inner wall of the adjustment groove is slidably connected to a telescopic sleeve, the upper end of the telescopic sleeve is frustum-shaped, and the inner wall of the upper end of the telescopic sleeve is fixedly connected to a fixing ring facing the inner diameter of the corresponding screen hole.

[0019] Preferably, the inner wall of the telescopic sleeve is provided with multiple grooves, and the inner wall of the groove is equipped with a spring that is fixedly connected to the inner wall of the adjustment groove. The upper end of the telescopic sleeve is slidably connected to the inner wall of the storage groove.

[0020] By adopting the above technical solution, the sieve structure can sample grains and screen them through sieve holes of different sizes opened on the fixed sleeve, and finally obtain the sample grains that need to be tested.

[0021] The beneficial effects of this invention are:

[0022] The drive sleeves installed at both ends of the snake-shaped main body can change the angle of rotation as needed, enabling the entire robot to move, turn, and descend. At the same time, the snake-like movement is more flexible and convenient, making it easier to find various locations in the grain silo and ensuring that every area in the grain silo can be detected, thus improving the overall detection accuracy of the grain in the grain silo. In conjunction with the multiple sensors installed on the snake-shaped main body, it is easy for the manager to adjust the position of the machine in a timely manner to reach the target point. The temperature and humidity sensors can transmit information in real time, helping the manager to more accurately grasp the changes in the environment inside the grain silo and ensure the quality of the grain. The pressure sensor can detect the pressure changes of the robot during the descent process, effectively avoiding damage to the robot.

[0023] The rotating adjustable sleeve in the sampling assembly continuously adjusts the feed position and the inner diameter and position of the sieve holes. When the feed hole becomes clogged due to the proximity effect, the rotation causes the end of the grain particles blocking the feed hole to collide with the material outside the feed hole, thus dislodging them from the feed hole. This effectively avoids clogging of the feed hole caused by simple horizontal screening. At the same time, after the adjusting sleeve continuously rotates to change the sieve holes, when the sieve holes and feed holes are aligned, in order to prevent some grain particles from going deep into the feed hole and causing blockage, the telescopic sleeve on the inner wall of the sieve hole rebounds under the action of the spring. The instantaneous thrust generated pushes the grain on the inner wall of the feed hole through the feed hole to clear the blockage, further maintaining the connectivity of the feed hole. This avoids grain blockage during the sampling process, thereby improving the subsequent collection efficiency. Attached Figure Description

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1, refer to Figures 1-12A multi-angle rotating robot capable of selective sampling includes multiple serpentine bodies 1 and connecting blocks 2 and drive sleeves 3 disposed on both sides of the serpentine bodies 1. The three serpentine bodies 1 are welded and fixed together on their sides. A first limiting groove 11 is opened at one end of the serpentine body 1 near both sides. A mounting base 12 is installed on one side of the serpentine body 1. A temperature and humidity sensor 6, an orientation sensor 7, and a pressure sensor 8 are respectively installed on the three mounting bases 12. Two connecting blocks 2 are respectively installed at one end of the two serpentine bodies 1. A first limiting ring 21 that is rotatably connected to the inner wall of the first limiting groove 11 is installed at one end of the connecting block 2. A second limiting ring 25 is installed at one end of the connecting block 2. Two drive sleeves 3 are respectively installed at one end of the two connecting blocks 2. A partition 32 is installed on the inner wall of one end of the drive sleeve 3. A second limiting groove 33 that is rotatably connected to the outer wall of the second limiting ring 25 is opened on one side of the drive sleeve 3. A screw conveyor blade 31 is installed on the outer side of the drive sleeve 3. A fixing port 35 is opened at one end of the drive sleeve 3. A replaceable conical head 4 and a sampling component 5 are installed on the inner wall of the fixing port 35.

[0040] The frontal cross-section of the serpentine body 1 is an isosceles trapezoid, the frontal cross-section of the connecting block 2 is a right trapezoid, one end of the drive sleeve 3 is a frustum-shaped sleeve, the inner walls of the two serpentine bodies 1 near the sides are fitted with a first internal gear ring 13, the connecting block 2 near the side of the serpentine body 1 is provided with a first mounting groove 22, the inner wall of the first mounting groove 22 is fitted with a first motor 23, the output end of the first motor 23 is fitted with a first gear 24 that meshes with the first internal gear ring 13, the connecting block 2 near the side of the drive sleeve 3 is provided with a second mounting groove 26, the inner wall of the second mounting groove 26 is fitted with a second motor 27, the output end of the second motor 27 is fitted with a second gear 28, and the inner wall of one end of the drive sleeve 3 is fitted with a second internal gear ring 34 that meshes with the second gear 28.

[0041] A multi-angle rotating robot capable of selective sampling is designed to address the problem that traditional barn robots cannot effectively adapt to the irregular spatial layout and complex stacking conditions inside barns.

[0042] Under normal conditions, the robot's overall axis is on the same horizontal line, and the ends of the drive sleeves 3 at both ends of the robot are designed to be tapered. This reduces air resistance and energy loss during movement while improving the movement efficiency. The second gear 28 in the connecting block 2, in conjunction with the second internal gear ring 34 in the drive sleeve 3, is driven by the second motor 27, thereby controlling the entire drive sleeve 3 to rotate around the vertical line of the midpoint of the connecting block 2. This, combined with the auger blades 31 on the outer side of the drive sleeve 3, pushes the surrounding grains, thus moving the entire machine. The auger blades 31 on both ends of the drive sleeve 3 have the same thread direction. When the robot moves forward or backward, the forward and reverse rotation of the second motor 27 is adjusted to achieve [further movement]. When the direction of movement changes, requiring turning or diving, the first internal gear ring 13 set inside both ends of the snake-shaped main body 1, together with the first gear 24 installed on the connecting block 2, is driven by the first motor 23. This causes the connecting block 2 and the drive sleeve 3 at one end to rotate about the vertical line at the center of the side of the snake-shaped main body 1. The required angle of rotation of the drive sleeves 3 at both ends is controlled, thereby changing the rotation direction of the robot's two ends. This enables the entire robot to turn and sink, allowing the robot to effectively adapt to the irregular spatial layout and complex stacking conditions inside the barn. At the same time, the snake-shaped movement is more flexible and convenient, making it easier for the robot to search and detect various locations in the barn and improving the detection range.

[0043] In the second embodiment, the side wall of one end of the conical head 4 is threaded to the inner wall of the fixing port 35, and the temperature and humidity sensor 6, the orientation sensor 7, the pressure sensor 8, and the mounting base 12 are all installed and fixed by threads.

[0044] In this embodiment, in order to collect environmental information in the barn, so as to make further judgments on the robot's movement;

[0045] The three serpentine bodies 1 are respectively equipped with a temperature and humidity sensor 6, an orientation sensor 7, and a pressure sensor 8. The temperature and humidity sensor 6 continuously collects the temperature and humidity data around the robot in the grain silo during movement to determine whether the storage environment of the grain is suitable. This helps managers to more accurately grasp the environmental changes inside the silo and avoid the impact of temperature and humidity outside the set range on grain storage, thereby ensuring the quality of the grain. The orientation sensor 7 determines the robot's position coordinates in real time, so as to adjust the robot's movement position in a timely manner and make it easy to reach the target point. This ensures that the entire area of ​​the grain silo is monitored, improving the accuracy of the detection. The pressure sensor 8 detects the pressure of the grain on the robot during descent, preventing excessive pressure from damaging the robot and thus extending its service life. The threaded sensors can be replaced as needed to collect different data in the grain silo, improving the robot's detection flexibility. At the same time, the conical head 4 threaded on one end of the drive sleeve 3 can reduce forward resistance and improve the movement efficiency.

[0046] In embodiment 3, the sampling component 5 includes a fixed sleeve 51 and an adjusting sleeve 58. The outer wall of the fixed sleeve 51 is threadedly connected to the inner wall of the fixed opening 35. A third motor 52 is installed on the inner wall of the fixed sleeve 51. The output shaft of the third motor 52 is fixedly connected to the inner wall of the adjusting sleeve 58 near the center. The inner wall of the adjusting sleeve 58 is rotatably connected to the outer wall of the fixed sleeve 51. The surface of the fixed sleeve 51 has several sieve holes 53 with different apertures. The surface of the adjusting sleeve 58 has a feed hole 59. The inner diameter of the feed hole 59 is the same as the inner diameter of the largest aperture sieve hole 53. Hole 59 is a frustum-shaped hole. The fixing sleeve 51 has multiple adjusting grooves 54 near the outer wall of the sieve hole 53. The inner wall of the adjusting groove 54 has a receiving groove 541. The inner wall of the adjusting groove 54 is slidably connected to the telescopic sleeve 55. The upper end of the telescopic sleeve 55 is frustum-shaped. The inner wall of the upper end of the telescopic sleeve 55 is fixedly connected to a fixing ring 56 facing the inner diameter of the corresponding sieve hole 53. The inner wall of the telescopic sleeve 55 has multiple grooves 551. The inner wall of the grooves 551 is installed with springs 57 that are fixedly connected to the inner wall of the adjusting groove 54. The upper end of the telescopic sleeve 55 is slidably connected to the inner wall of the receiving groove 541.

[0047] In this embodiment, in order to effectively screen and sample grains during movement while avoiding clogging of the sampling component 5 by grains near the sieve holes 53;

[0048] When sampling grains in a localized area of ​​the barn is required, the conical head 4 at one end of the drive sleeve 3 is removed and replaced with the sampling component 5. After the robot descends to the sampling position, the third motor 52 is activated to control the rotation of the adjusting sleeve 58 while simultaneously driving the robot to move. During the rotation of the adjusting sleeve 58, the grains in the feed hole 59 pass through the sieve hole 53 and are collected inside the drive sleeve 3 as the robot moves. Simultaneously, during the rotation, grains larger than the sieve hole 53 but smaller than the feed hole 59 remain in the feed hole 59 and rotate along with it until the inner diameter of the corresponding sieve hole 53 is larger than the grain size. At this point, during the robot's movement, the grains are pushed through the sieve hole 53 and collected inside the drive sleeve 3. By continuously changing the inner diameter of the sieve hole 53 and rotating the position of the feed hole 59, when the feed hole 59 becomes blocked due to the proximity effect, the rotation helps to clear the blockage. Grain particles clogging the feed hole 59 collide with the material outside the feed hole 59, causing them to detach from the feed hole 59. This effectively avoids clogging of the feed hole 59 caused by simple horizontal screening. To prevent some grain particles from becoming deeply embedded in the feed hole 59 and causing blockage, after the adjusting sleeve 58 rotates continuously to change the sieve hole 53, when the sieve hole 53 and the feed hole 59 are level, the telescopic sleeve 55 on the inner wall of the sieve hole 53 rebounds under the action of the spring 57. The instantaneous thrust pushes the grain on the inner wall of the feed hole 59 through the feed hole 59, keeping one end of the telescopic sleeve 55 level with the outer wall of the feed hole 59. The fixing ring 56 on the inner wall of one end of the telescopic sleeve 55 restricts the size of the grain particles, ensuring that the apertures of the feed hole 59 and the sieve hole 53 are consistent. This prevents the opening of the telescopic sleeve 55 from being larger than the inner diameter of the sieve hole 53, thus preventing grain from clogging the telescopic sleeve 55 and further avoiding blockage during sampling, improving subsequent collection efficiency.

[0049] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0050] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
