Description

Technical Field

[0001] The utility model belongs to the technical field of grain processing equipment, and specifically relates to an intelligent multi-tube sampling machine for grains of multiple varieties. Background Art

[0002] The intelligent grain sampling machine uses negative pressure vacuum adsorption to suck dry bulk grain from the transport vehicle into the grain storage tank, mix and separate the grain, and then transport it to the laboratory. Sampling, mixing and transportation are all completed in the same operation. Information is closed to avoid human intervention. It is extremely simple and convenient to use, which greatly improves the efficiency and benefits of grain sampling.

[0003] Before the grain enters the warehouse, the manufacturer sets up a sampling inspection station to extract a certain amount of grain as samples using a number of sampling tubes. The inspection station consists of two overhead rails, between which a number of cranes are used to drive the sampling tubes to move forward and backward. The cranes are also equipped with lifting equipment to lower or raise the sampling tubes, as well as displacement equipment to move the sampling tubes left and right.

[0004] After the existing grain truck arrives at the sampling point, it lowers several sampling tubes and randomly samples from different positions. However, the part of the sampling tube inserted into the grain cannot be photographed by the camera, and the length of the remaining exposed part cannot be automatically measured, making it difficult to intuitively feedback the sampling depth to the control system, which is not conducive to the intelligent adjustment of the sampling depth. For this reason, we propose an intelligent multi-tube sampling machine for multi-variety grains. Utility Model Content

[0005] The purpose of the utility model is to provide an intelligent multi-tube sampling machine for multiple varieties of grains, which can obtain the sampling depth of the sampling tube in real time and intuitively feed back to the central control computer to facilitate the intelligent adjustment of the sampling depth.

[0006] The technical solutions adopted in this utility are as follows:

[0007] A multi-variety grain intelligent multi-tube sampling machine comprises two side-by-side overhead rails, a plurality of carriages are slidably installed between the upper surfaces of the two overhead rails, a displacement mechanism and a lifting mechanism fixedly connected to the displacement mechanism are arranged on the carriages, two sampling tubes fixedly connected to the lifting mechanism are arranged outside the carriages, the opening directions of the sampling tubes are all downward, and the outer sides of the sampling tubes are all provided with rangefinders, movable rings and two stoppers from top to bottom, the ends of the rangefinders are all fixedly connected to the upper edges of adjacent sampling tubes, the movable rings are all sleeved on the outsides of adjacent sampling tubes, the upper surfaces of the movable rings are all directly facing the detection ends of the adjacent rangefinders, the stoppers are all fixedly connected to the adjacent sampling tubes, the width The speed and height information are used to activate the drive module to move the vehicle forward and backward, and the displacement mechanism moves the sampling tube left and right to reach the top of the grain truck. The lifting mechanism is then started to lower the sampling tube and the rangefinder, driving the detection end of the rangefinder to gradually sink into the grain, while the movable ring is blocked by the grain and stays on the upper surface of the grain. At this time, the rangefinder detects the real-time distance to the movable ring. The initial distance of the movable ring is subtracted from the real-time distance to obtain the sampling depth of the sampling tube in real time, which is intuitively fed back to the central control computer for intelligent adjustment of the sampling depth. The fan is then used to suck the air in the sampling tube to form a negative pressure environment to absorb a certain amount of grain as a sample. After sampling, the fan is stopped and the sampling tube is raised.

[0008] The upper surfaces of the blocks are fixed with slide rails along the axial direction of the adjacent sampling tubes, and the slide rails are fixedly connected to the adjacent sampling tubes. The two slide rails are used to guide the movable ring, so that the movable ring remains stable and is always aligned with the rangefinder.

[0009] Two limiting grooves are arranged on the inner side of the movable ring, and the limiting grooves are penetrated by corresponding slide rails. The limiting grooves cover the slide rails and can limit horizontally to prevent the movable ring from rotating outside the sampling tube and reduce unnecessary friction.

[0010] The displacement mechanism includes two slides slidably installed on one side of the carriage, and a travel motor is fixed on the upper surface of the slides. After the travel motor is started, the forward gear can drive the slide and the sampling tube to move to the left, and conversely, the reverse gear can drive the slide and the sampling tube to move to the right. The left and right movement range can be controlled by a program.

[0011] The lifting mechanism includes two lifting motors fixedly connected to adjacent slides, and belts are rotatably installed on the output ends of the lifting motors. The belts are fixedly connected to adjacent sampling tubes, and the belts are rotatably connected to adjacent slides. The upper ends of the belts extend upward. The lifting motors are started and the belts are rotated forward to drive the sampling tubes to rise, or the belts are reversed to drive the sampling tubes to lower. At this time, the sampling tubes are lifted vertically and can face the grain.

[0012] A fixing seat is also fixed on the upper edge of the sampling tube, and the fixing seat is fixedly connected to the belt to increase the connection area between the sampling tube and the belt, so as to improve the stability of driving the sampling tube to rise and fall and reduce the swing amplitude of the sampling tube.

[0013] The technical effects achieved by this utility model are:

[0014] The utility model discloses a multi-variety grain intelligent multi-tube sampling machine. When entering the grain vehicle, the license plate information is photographed by a camera and recorded in a server. With the corridor exit as a reference, according to the vehicle length, width and height and other information of the grain vehicle, the driving device module is activated to move the vehicle forward and backward, and the displacement mechanism moves the sampling tube left and right to reach the top of the carriage of the grain vehicle. Then the lifting mechanism is started to lower the sampling tube and the rangefinder, driving the detection end of the rangefinder to gradually sink into the grain, and the movable ring is blocked by the grain and stays on the upper surface of the grain. At this time, the rangefinder detects the real-time distance with the movable ring, and the sampling depth of the sampling tube can be obtained in real time by subtracting the real-time distance from the initial distance of the movable ring. The sampling depth is intuitively fed back to the central control computer for intelligent adjustment of the sampling depth, and then the fan is used to suck the air in the sampling tube to form a negative pressure environment to absorb a certain amount of grain as a sample. After sampling, the fan is stopped and the sampling tube is raised. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0023] like Figure 1-5 As shown, a multi-variety grain intelligent multi-tube sampling machine comprises two side-by-side overhead rails 1, a plurality of carriages 2 are slidably mounted between the upper surfaces of the two overhead rails 1, a displacement mechanism and a lifting mechanism fixedly connected to the displacement mechanism are arranged on the carriages 2, two sampling tubes 3 fixedly connected to the lifting mechanism are arranged outside the carriages 2, and a Chinese utility model intelligent sampling machine with a reference announcement number of CN220542548U is provided, the upper ends of the sampling tubes 3 are connected and fixed with fans, and a driving device module and a parking module are arranged on the overhead rails 1, which can It is used to move the driving vehicle 2 forward and backward. The opening direction of the sampling tube 3 is downward. The outer side of the sampling tube 3 is provided with a rangefinder 4, a movable ring 5 and two blocks 6 from top to bottom. The displacement mechanism, the lifting mechanism and the rangefinder 4 are all connected to the central control computer by signal so as to be intelligently controlled through a preset program. The rangefinder 4 can use an industrial-grade laser distance sensor of the MSE-LT200B model, which can measure a range of 0 to 30m. The ends of the rangefinders 4 are fixedly connected to the upper edge of the adjacent sampling tube 3, and the movable rings 5 ​​are sleeved on the outer side of the adjacent sampling tube 3. The upper surface of the movable ring 5 is directly opposite to the detection end of the adjacent rangefinder 4, and the block 6 is fixedly connected to the adjacent sampling tube 3. The space between the ceiling rail 1 and the ground forms a grain truck parking corridor. A vehicle identification gate can be set at the entrance of the corridor. When entering the grain truck, the license plate information is photographed by the camera and recorded in the server. Based on the corridor exit as a reference, according to the vehicle length, width and height of the grain truck, the driving device module is activated to move the driving vehicle 2 forward and backward, and the displacement mechanism moves the sampling tube 3 left and right to reach the top of the grain truck compartment, and then the lifting mechanism is started to lower the vehicle. The lower sampling tube 3 and the rangefinder 4 drive the detection end of the rangefinder 4 to gradually sink into the grain, while the movable ring 5 is blocked by the grain and stays on the upper surface of the grain. At this time, the rangefinder 4 detects the real-time distance with the movable ring 5. The sampling depth of the sampling tube 3 can be obtained in real time by subtracting the real-time distance from the initial distance of the movable ring 5. The feedback is intuitively given to the central control computer to facilitate intelligent adjustment of the sampling depth. Then, the fan is used to suck the air in the sampling tube 3 to form a negative pressure environment to absorb a certain amount of grain as a sample. After sampling, the fan is stopped and the sampling tube 3 is raised.

[0024] Finally, the sampling tube 3 is separated from the grain, and the movable ring 5 slides down along the sampling tube 3 until it is limited by the stopper 6 to prevent it from sliding down.

[0025] The above-mentioned intelligent adjustment of sampling depth means that the sampling depth can be known in real time on the central control computer, and the height of the sampling tube can be dynamically adjusted according to the preset sampling depth corresponding to the grain variety. Within 1.5 seconds, the sampling depth can be reached to be the same as the preset sampling depth. The total sampling process does not exceed 10 seconds, and the sampling efficiency of multiple grain varieties is high.

[0026] In particular, the intelligent closed grain sampling equipment used in the ZFQ-17.5 / 4.5 model can be equipped with a high-pressure silent vortex fan, with low sampling noise and a long service life. The vacuum adsorption pressure is about 0.6MPa, the vacuum degree is small, the safety level is high, and the maximum conveying distance can reach more than 50 meters.

[0027] like Figure 3 and Figure 5 As shown, the upper surface of the block 6 is fixed with a slide rail 7 along the axial direction of the adjacent sampling tube 3, and the slide rail 7 is fixedly connected to the adjacent sampling tube 3. The two slide rails 7 are used to guide the movable ring 5, so that the movable ring 5 remains stable and is always aligned with the rangefinder 4.

[0028] like Figure 3 and Figure 5 As shown, two limiting grooves 8 are provided on the inner side of the movable ring 5, and the limiting grooves 8 are penetrated by the corresponding slide rails 7. The limiting grooves 8 are sleeved on the slide rails 7 and can be limited horizontally to prevent the movable ring 5 from rotating outside the sampling tube 3 and reduce unnecessary friction.

[0029] like Figure 2 and Figure 4 As shown, the displacement mechanism includes two slides 9 slidably mounted on one side of the crane 2, and travel motors 10 are fixed on the upper surfaces of the slides 9. The signals of the travel motors 10 are connected to the central control computer. The travel motors 10 can use YEJ series brake motors. The output end of the travel motor 10 is fixed with a gear meshing with the rack on the upper surface of the crane 2. After the travel motor 10 is started, the forward gear can drive the slide 9 and the sampling tube 3 to move to the left, and conversely, the reverse gear can drive the slide 9 and the sampling tube 3 to move to the right. The left and right movement range can be controlled by a program.

[0030] like Figure 2 and Figure 4 As shown, the lifting mechanism includes two lifting motors 11 fixedly connected to adjacent slides 9. The lifting motors 11 are all connected to the central control computer by signal. The lifting motors 11 can use YEJ series brake motors. The output ends of the lifting motors 11 are rotatably installed with belts 12. Two guide wheels are arranged inside the belts 12 from bottom to top. The guide wheels are rotatably connected to the adjacent slides 9. The belts 12 are fixedly connected to the adjacent sampling tubes 3. The belts 12 are rotatably connected to the adjacent slides 9. The upper ends of the belts 12 extend upward. Start the lifting motor 11 and rotate the belt 12 forward to drive the sampling tube 3 to rise, or reverse the belt 12 to drive the sampling tube 3 to lower. At this time, the sampling tube 3 is lifted vertically and can face the grain.

[0031] like Figure 1 and Figure 2As shown, a fixing seat 13 is also fixed on the upper edge of the sampling tube 3, and the fixing seat 13 is fixedly connected to the belt 12 to increase the connection area between the sampling tube 3 and the belt 12, so as to improve the stability of driving the sampling tube 3 to rise and fall and reduce the swing amplitude of the sampling tube 3.

[0032] The working principle of the utility model is as follows: when entering the grain truck, the license plate information is photographed by a camera and recorded in the server, and based on the corridor exit and the vehicle length, width and height of the grain truck, the driving device module is activated to move the vehicle 2 forward and backward, and the displacement mechanism moves the sampling tube 3 left and right to reach the top of the grain truck compartment, and then the lifting mechanism is started to lower the sampling tube 3 and the rangefinder 4, driving the detection end of the rangefinder 4 to gradually sink into the grain, while the movable ring 5 is blocked by the grain and stays on the upper surface of the grain.

[0033] At this time, the rangefinder 4 detects the real-time distance from the movable ring 5, and the sampling depth of the sampling tube 3 can be obtained in real time by subtracting the real-time distance from the initial distance of the movable ring 5, which is intuitively fed back to the central control computer for intelligent adjustment of the sampling depth.

[0034] Then, a fan is used to suck the air in the sampling tube 3 to form a negative pressure environment to absorb a certain amount of grain as a sample. After sampling, the fan is stopped and the sampling tube 3 is raised.

[0035] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
