Description

[0002] In the field of modern grain storage and detection, the sampling machine as an important tool is widely used in the process of grain storage, detection and quality control. The main function of the sampling machine is to collect grain samples by penetrating the sampling rod into the grain pile, so as to facilitate subsequent quality analysis and detection.

[0055] In the existing sampling machine, the sampling rod is usually hoisted on the connecting rod, and the connecting rod drives the movement of the sampling rod through the rotation or lifting action of the end thereof, so as to realize the up-down movement of the sampling rod. Since the sampling rod is driven at the end of the connecting rod during the sampling process, the sampling rod is in a cantilever shape in the grain pile. This cantilever structure is unstable in mechanics, especially when the sampling rod penetrates into the grain pile, due to the resistance inside the grain pile and the weight of the sampling rod, the sampling rod is easily bent, which not only affects the accuracy and efficiency of sampling, but also may cause damage to the sampling rod, thereby reducing the service life of the sampling rod.

The sample holder 51 is slidably arranged on the track groove 511, that is, during the up-down movement of the sample holder 52, part of the sample holder 51 is always coincident with the sample holder 51 and arranged close to each other, which can increase the structural strength of the sample holder 52 in the length direction, ensure that the sample holder 52 is not easy to bend during the sampling process, and thus the reliability and accuracy of sampling are improved. Through the sliding of the walking mechanism 3 on the track mechanism 2, the sampling mechanism 5 can be driven to perform the sampling action at any position in the first direction; in addition, the rotating mechanism 4 is also provided in the scheme, so that the sampling mechanism 5 can be adjusted in position in all directions and at multiple angles under the driving of the rotating mechanism 4 when walking to a position in the first direction, so that sampling can be performed in a larger range to adapt to different sampling environments.

[0064] Specifically, the length of the sample holder 51 is not limited, for example, the length of the sample holder 52 can be almost equal to that of the sample holder 52, so that the sample holder 51 can provide long length support to the sample holder 52 during sampling. In addition, the length of the track groove 511 can be designed according to the length of the sampling distance, and a lubricating strip can be arranged at the slot opening of the track groove 511, so that the sample holder 52 can slide smoothly.

[0065] In the embodiment of the utility model, please refer to Figure 2 And Figure 3 The sample holder 52 comprises:

[0066] The buffer box 521 is slidably arranged on the track groove 511, and the buffer box 521 is provided with a limiting groove 5211;

[0067] A sampling rod 522 is arranged through the buffer box 521, and a limiting ring 5221 is fixedly arranged on the outer periphery of the sampling rod 522, and the limiting ring 5221 is slidingly arranged in a limiting groove 5211, and

[0068] A first elastic member 523 is sleeved on the outer periphery of the sampling rod 522, one end of the first elastic member 523 abuts against the top surface of the buffer box 521, and the other end of the first elastic member 523 abuts against the limiting ring 5221.

[0069] Specifically, through cooperation of the limiting ring 5221 on the sampling rod 522 and the first elastic member 523, the sampling rod 522 can be provided with a buffering effect, so that the impact force received by the sampling rod 522 during sampling is reduced, and the service life of the sampling rod 522 is prolonged. In the specific implementation process, when the sampling rod 522 is static, the first elastic member 523 is in a natural state, and the limiting ring 5221 is located at the starting position of the limiting groove 5211; when the sampling machine 100 starts to work, the sampling rod 522 and the buffer box 521 are driven to move downward along the track groove 511 under the driving of an external power source (such as a motor), until the sampling rod 522 touches the bottom, at which moment, the buffer box 521 is subjected to a large impact, and the sampling rod 522 remains static, and the buffer box 521 continues to move downward under the driving of the external power source, the limiting ring 5221 on the outer periphery of the sampling rod 522 slides in the limiting groove 5211 and compresses the first elastic member 523, and the compression of the first elastic member 523 provides necessary buffering force for the sampling rod 522 to continue to move downward; when the sampling rod 522 reaches a predetermined sampling depth, the sampling rod 522 and the buffer box 521 both stop moving; after sampling is completed, the sampling rod 522 needs to be retracted to the initial position. In the retraction process, the buffer box 521 is first moved upward by a small distance under the driving of an external force, so that the first elastic member 523 gradually returns to the natural state, and the limiting ring 5221 also slides in the limiting groove 5211 to return to the starting position, and then the sampling rod 522 moves upward together with the buffer box 521.

When the first driving assembly 53 (motor) is started, the motor starts to rotate, drives the first gear connected with the gear system through the output shaft, and the rotation of the first gear is transmitted to other gears in the gear system through meshing. The gears mesh in sequence to transmit the power to the final gear connected with the sampling rod assembly 52, and the rotation of the final gear drives the sampling rod assembly 52 to move along the track groove 511, so as to realize the sampling operation. When it is needed to retreat the sampling rod assembly 52, the rotation direction of the first driving assembly 53 (motor) can be reversed, and the sampling rod assembly 52 is reversely driven through the transmission assembly 54 to return to the initial position.

In other embodiments, a limiting assembly can also be arranged on the walking frame 31. The limiting assembly comprises a limiting shaft and a limiting wheel. The limiting shaft is fixedly arranged on the base of the second driving assembly 33, and the limiting wheel is fixedly arranged on the limiting shaft and arranged on the back of the rack 22 close to the walking rail 21. When a fault or other unexpected situation occurs, the gear on the output shaft of the second driving assembly 33 cannot disengage from the engagement with the rack 22 due to the blocking of the limiting wheel, so that the phenomenon of tooth skipping can be avoided, and the gear and the rack 22 are protected.

[0094] In the embodiment of the utility model, please refer to Figure 8 , the rotating mechanism 4 comprises:

[0095] The rotating seat 41 is rotatably arranged on the walking frame 31.

[0096] The bogie 42 is fixedly arranged at one end of the rotating seat 41, and the sampling mechanism 5 is fixedly arranged at the other end of the bogie 42.

[0097] The third driving assembly 43 is installed on the side of the rotating seat 41 facing the walking mechanism 3 and is drivingly connected with the rotating seat 41.

[0098] Specifically, the third driving assembly 43 can be a servo motor or other mechanical device with driving effect, and the rotating seat 41 can be a rotating wheel meshing with the gear outside the output shaft of the third driving assembly 43 for transmission. Through the driving of the third driving assembly 43, the rotating seat 41 can be driven to rotate within a certain angle range, and the bogie 42 will follow the rotating seat 41 to rotate synchronously, thereby driving the synchronous rotation of the sampling mechanism 5 to sample within a wider range. One end of the bogie 42 can be fixedly installed on the rotating seat 41 by welding or riveting, and the other end of the bogie 42 is provided with the sampling mechanism 5, which can be installed and fixed by welding, riveting or threaded connection. Alternatively, a counterweight frame is further provided on the side of the bogie 42 away from the sampling mechanism 5, and by adjusting the counterweight of the counterweight frame to match the weight of the sampling mechanism 5, the center of gravity can be obviously changed, the stress condition can be improved, and the bogie can be balanced in the horizontal direction. Further, a stabilizing rod can be further provided on the bogie 42, and the stabilizing rod and the counterweight frame are respectively provided on both sides of the main body of the bogie 42. By pre-tightening the stabilizing rod, the rigidity of the equipment is increased, and at the same time, the stabilizing rod changes the structure of the rotating frame, increases the stress point, effectively improves the stress structure, and improves the stability. It should be pointed out that the two ends of the stabilizing rod connected with the bogie 42 can be respectively provided with right and left threads to optimize the installation process, and ball bearings are used at the two ends to eliminate the influence of machining errors.

[0099] Of course, the sampling machine 100 can also be combined according to the specific implementation needs of the above-mentioned various embodiments, and the specific implementation process is as follows: when the sampling machine 100 receives the sampling start instruction, the second driving assembly 33 drives the walking mechanism 3 to move along the extension direction of the walking rail 21, and at the same time, the third driving assembly 43 drives the bogie 42 to rotate around the second direction, so that the sampling mechanism 5 leaves the original position. Under the joint driving of the second driving assembly 33 and the third driving assembly 43, the sampling mechanism 5 reaches above the sampling point, at which time the second driving assembly 33 and the third driving assembly 43 stop running, the first driving assembly 53 drives the rotation of the transmission chain 542, and drives the sampling rod 522 to be sampled downward. At this time, with the increase of the sampling depth of the sampling rod 522, the reaction force received by the whole equipment also increases. When the sampling rod 522 contacts the bottom of the grain car, the first driving assembly 53 receives a stop signal, and the sampling rod 522 stops sampling downward, and then reversely moves the first driving assembly 53 to drive the sampling rod 522 to rise. In particular, at the moment when the sampling rod 522 touches the bottom, the sampling rod 522 remains stationary, the buffer box 521 continues to move downward under the driving of the transmission chain 542, and the limiting ring 5221 of the sampling rod 522 presses the first elastic element 523, so that it is buffered. At the same time, the transmission chain 542 is inevitably lengthened during repeated movement, and the second elastic element 543 arranged at the buffer wheel 541 can tension the transmission chain 542, so as to ensure the stable operation of the equipment. When the sampling rod 522 rises to the position, the first driving assembly 53 receives a stop signal, at which time the second driving assembly 33 and the third driving assembly 43 work simultaneously to move the sampling mechanism 5 to the next sampling point or to the starting position. In the above working process, the second driving assembly 33 and the third driving assembly 43 are needed to address the sampling point position, and only the first driving assembly 53 is needed to complete the sampling process, so as to avoid linkage control, and the three driving assemblies drive the movement of the sampling rod 522 respectively, so that the positioning of the target sampling position is more accurate. The sampling rod 522 and the sampling framework 51 move vertically upward and downward separately, which greatly reduces the risk of bending, and at the same time, the walking rail 21 is added, so that the range of the sampling point is greatly improved, and the sampling range can be better balanced. Through the movement of the walking mechanism 3 along the track mechanism 2 in the first direction and the rotation of the rotating mechanism 4, the whole car range on both sides of the track mechanism 2 can be covered, and the sampling process does not need to re-adjust the parking position, and the control system can realize the original point resampling.
