Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain sampling technology, and in particular to a lifting and sampling mechanism for a grain sampling robot. Background Technology
[0002] A grain sampling robot is an intelligent device specifically designed for the grain industry to collect samples of various types of grain. It can accurately collect representative grain samples from grain piles according to preset sampling rules and standards.
[0003] The working process of a grain sampling robot is roughly as follows: by installing a sampling component at the bottom, when the grain sampling robot moves above the grain material, the sampling component lifts the grain material into the inside of the grain sampling robot and transports it into a container, thereby completing the sampling.
[0004] In the prior art, sampling components typically employ spiral sampling, which involves collecting grain materials through a spiral lifting component. However, during the sampling process, the depth to which the sampling component inserts into the grain material is relatively fixed, resulting in the acquired sample parameters being from the same or similar layers. This makes it impossible to conduct accurate quality testing on the grain materials. Therefore, this application provides a grain sampling robot lifting sampling mechanism to meet the requirements. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a lifting sampling mechanism for a grain sampling robot to solve the problem that existing sampling components usually use spiral sampling, that is, the grain material is sampled and collected by a spiral lifting component. However, during the sampling process, the depth of the sampling component inserted into the grain material is relatively fixed, which will result in the obtained sample parameters being all from the same or similar layers, thus making it impossible to accurately test the quality of the grain material.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a lifting and sampling mechanism for a grain sampling robot, comprising: a robot body; a storage bin installed in the robot body; a fixed plate installed in the robot body; a sliding track installed on the fixed plate; a lifting component installed on the track; two sets of connecting components installed on both sides of the sliding track and slidably connected to the sliding track; a material-taking component installed between the two sets of connecting components and hinged to both sets of connecting components; and a transmission frame installed on the lifting component and fixedly connected to both sets of connecting components, so that when the transmission frame moves upward or downward with the lifting component, the two sets of connecting components and the material-taking component also move accordingly.
[0007] Preferably, it further includes: two sets of miniature electric push rods, each set of miniature electric push rods is installed on each connecting member; a push-pull ring, located at the bottom end of the material taking member, the push-pull ring engages with the bottom end of the material taking member and is connected to the two sets of miniature electric push rods, and is configured to push and pull the bottom end of the material taking member when the two sets of miniature electric push rods extend or shorten, so that the grain material in the material taking member enters the storage chamber.
[0008] Preferably, the two sets of miniature electric actuators extend or retract simultaneously, and the extension or retraction distances are equal.
[0009] Preferably, it further includes: a groove formed on the side of the sliding track near the storage compartment for installing the lifting component.
[0010] Preferably, it further includes: two sets of sliding grooves, which are respectively opened on both sides of the sliding track, and the two sets of sliding grooves are respectively located on the left and right sides of the groove; two sets of small sliders, each set of sliding grooves is slidably connected to a set of small sliders, and the side of each set of small sliders away from the sliding track is fixedly connected to a set of connecting parts.
[0011] Preferably, the cross-section of the material is an inverted isosceles trapezoid, and the bottom of the two sets of hypotenuses of the isosceles trapezoid engages with the push ring.
[0012] Preferably, when the lifting member raises the sampling member to its maximum distance, the lowest point of the sampling member is higher than the highest point of the storage hopper, so that the material enters the storage hopper after the sampling member is tilted.
[0013] Preferably, the push-pull ring includes a connecting area and a locking area. The connecting area is used to connect the miniature electric push rod, and the locking area includes two sets of locking strips, which are symmetrically arranged about the central axis of the sampler so that the sampler engages with the two sets of locking strips.
[0014] Compared with the prior art, this utility model has at least the following beneficial effects: 1. In the above solution, by setting up structures such as lifting components, sliding tracks, and connecting components, the lifting components are installed on the slide rail. The movement of the lifting components on the slide rail can drive the transmission frame, connecting components, and material picking components connected to them to move up and down. This allows for flexible adjustment of the depth of the material picking components inserted into the grain material, enabling sampling of materials at different levels of the grain pile. The samples obtained come from multiple different levels. Compared with the existing spiral sampling technology, the samples are more representative and more conducive to accurately grasping the overall quality status of the grain material.
[0015] 2. In the above scheme, by setting two sets of miniature electric push rods and push-pull rings, the miniature electric push rods are installed on the connector and connected to the push-pull ring at the bottom of the material taking part. The two sets of miniature electric push rods can extend or retract simultaneously with equal distances. When the material taking part picks up materials at different levels, the push-pull action of the miniature electric push rods on the push-pull ring can accurately push the grain material in the material taking part into the storage bin. This effectively ensures the integrity of the sample from sampling to collection, avoids sample omissions, and enables subsequent quality tests based on these samples to more accurately reflect the actual quality of the grain material.

Detailed Implementation
[0025] The following is a detailed description of the lifting and sampling mechanism of a grain sampling robot provided by this utility model, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; for some known technologies, those skilled in the art can also use other alternative methods to implement them; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.
[0026] Example 1: As Figures 1 to 5 As shown, an embodiment of this utility model provides a lifting and sampling mechanism for a grain sampling robot, comprising: a robot body 1; a storage compartment 2 installed in the robot body 1; a fixed plate 3 installed in the robot body 1; a sliding track 4 installed on the fixed plate 3; a lifting member 5 installed on the track; two sets of connecting members 6 respectively installed on both sides of the sliding track 4 and slidably connected to the sliding track 4; a material-taking member 7 installed between the two sets of connecting members 6 and hinged to both sets of connecting members 6; and a transmission frame 8 installed on the lifting member 5 and fixedly connected to both sets of connecting members 6, so that when the transmission frame 8 moves upward or downward with the lifting member 5, the two sets of connecting members 6 and the material-taking member 7 also move accordingly.
[0027] It should be noted that the lifting component 5 can adopt a structure such as a hydraulic rod or a cylinder, and its bottom is fixed on the bottom wall of the groove 11. The telescopic part of the lifting component 5 is located at the top, and it drives the transmission frame 8 to move by moving up or down. The sliding track 4 is set to be narrower at the top to reduce the overall mass of the robot body 1 and increase the endurance of the robot body 1.
[0028] Example 2: Figure 5 As shown, it also includes: two sets of miniature electric push rods 9, each set of miniature electric push rods 9 is installed on each set of connecting parts 6; push-pull ring 10, located at the bottom end of the material taking part 7, the push-pull ring 10 is engaged with the bottom end of the material taking part 7 and connected to the two sets of miniature electric push rods 9, and is configured to push and pull the bottom end of the material taking part 7 when the two sets of miniature electric push rods 9 extend or shorten, so that the grain material in the material taking part 7 enters the storage chamber 2.
[0029] Two sets of miniature electric actuators 9 extend or retract simultaneously, and the extension or retraction distances are equal.
[0030] like Figures 3 to 5 As shown, it also includes: a groove 11, which is formed on the side of the sliding track 4 near the storage compartment 2, for installing the lifting component 5.
[0031] like Figures 3 to 5As shown, it also includes: two sets of sliding grooves 12, which are respectively opened on both sides of the sliding track 4, and the two sets of sliding grooves 12 are respectively located on the left and right sides of the groove 11; two sets of small sliders 13, each set of sliding grooves 12 is slidably connected to a set of small sliders 13, and the side of each set of small sliders 13 away from the sliding track 4 is respectively fixedly connected to a set of connecting parts 6.
[0032] like Figure 5 As shown, the cross-section of the material component 7 is an inverted isosceles trapezoid, and the bottom of the two sets of hypotenuses of the isosceles trapezoid engages with the push ring.
[0033] When the lifting component 5 lifts the sampling component to its maximum distance, the lowest point of the sampling component is higher than the highest point of the storage chamber 2, so that after the sampling component tilts, the material enters the storage chamber 2.
[0034] like Figure 4 As shown, the push-pull ring 10 includes a connecting area 14 and a locking area 15. The connecting area 14 is used to connect the miniature electric push rod 9. The locking area 15 includes two sets of locking strips, and the two sets of locking strips are symmetrically arranged about the central axis of the sampler so that the sampler can engage with the two sets of locking strips.
[0035] It should be noted that the connector 6, push-pull ring 10, sampling component and transmission frame 8 are all made of lightweight materials, such as aluminum alloy, polytetrafluoroethylene or carbon fiber composite material. They cooperate with each other during operation and will not conflict with the existing structural positions in the robot body 1 after movement, thereby damaging the robot body 1.
[0036] In the above scheme, the operation of the robot body 1 controlling the lifting component 5 and the micro electric push rod 9 are all existing technologies, controlled by existing control systems. This is common knowledge in the field and is understood by practitioners in this industry, so it will not be elaborated here.
[0037] The technical solution provided by this utility model involves manipulating the robot body 1 to move near the grain material pile to be sampled, aligning the picking component 7 above the sampling location, and maintaining the robot body 1 and the picking component 7 in a stable position after the picking component 7 reaches the predetermined sampling depth. Based on the preset sampling depth requirements or the actual situation of the grain material pile, the lifting component 5 is activated to move downward on the sliding track 4. The lifting component 5 drives two sets of connecting components 6 to slide along both sides of the sliding track 4 through the transmission frame 8, inserting the sampling component into the grain material pile, so that the grain material gradually enters the picking component 7, completing the sampling action.
[0038] After sampling, the lifting component 5 moves upward on the sliding track 4. The lifting component 5, via the transmission frame 8, drives two sets of connecting components 6 to slide along both sides of the sliding track 4. Once the lifting component reaches its maximum distance, the two sets of miniature electric push rods 9 are activated. The miniature electric push rods 9 extend, causing the push-pull ring 10 connected to them to move horizontally towards the sampling component. Since the material taking component 7 has an inverted isosceles trapezoidal cross-section and engages with the push-pull ring 10, under the action of the push-pull ring 10, the material taking component 7 gradually tilts and sprinkles material towards the storage chamber 2, pushing the grain material into the storage chamber 2, thus completing the sample collection process.
[0039] If multiple samplings are required at different depths or locations, simply change the extension length of the lifting component 5 and repeat the above sampling steps. After completing all the predetermined sampling tasks, the robot body 1 leaves the sampling area, retrieves the samples from the storage bin 2 containing the collected samples, and sends them to the laboratory for subsequent quality testing and analysis.
[0040] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits have not been described in detail.
[0041] The above description is only a preferred embodiment of the present utility model. 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 utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
