Description

Technical Field

[0001] The utility model relates to a sampling device, in particular to a temporary material receiving device in sampling, belonging to the technical field of mechanical equipment. Background Art

[0002] In material sampling, some manufacturers need to perform fixed-point stratified sampling, which is to collect samples at different depths at one location, and then collect the samples collected at different depths and enter the next process or enter the next process separately according to the requirements. The current three-axis sampling system can complete this task, but the three-axis sampling system has three drive shafts, which is large in size and high in cost. Due to the complexity of the system, its adoption is also slow. Because fixed-point sampling only samples at one point, in theory, it only requires the sampling head to move up and down to achieve sampling, that is, a drive shaft in the up and down direction can complete the sampling action, but how to transfer the collected samples is a problem that needs to be solved. Summary of the invention

[0003] The utility model aims to provide a material receiving and transferring device in sampling for fixed-point stratified sampling.

[0005] Furthermore, a limit plate is fixedly installed on the bracket, the pin passes through the limit plate, the pin has an elastic limit part, a reset spring is passed through the pin between the spring limit part and the limit plate, after the pin is disengaged from the pin hole, the spring limit part compresses the reset spring toward the limit plate.

[0006] Furthermore, a reducer is connected to the output shaft of the motor, a driving gear is fixedly connected to the output shaft of the reducer, a driven gear is fixedly connected to the rotating shaft, and the driven gear is meshed with the driving gear.

[0007] Furthermore, a proximity body is connected to the latch, and one or two proximity switches sensing the proximity body are installed on the bracket.

[0008] The material receiving and transferring device can be used in combination with a sampling head that moves up and down to realize fixed-point stratified sampling, thereby reducing equipment costs and equipment installation space. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to more fully explain the implementation of the utility model, implementation examples of the utility model are provided. These implementation examples are only for the purpose of illustrating the utility model and do not limit the scope of the utility model.

[0013] The present invention is further explained in detail in conjunction with the accompanying drawings, in which the following marks are: 1: frame; 2: motor; 3: reducer; 4: driving gear; 5: bracket; 6: hopper; 7: rotating bottom valve plate; 8: connecting handle; 9: latch; 10: driving plate; 11: reset spring; 12: rotating shaft; 13: driven gear; 14: traction electromagnet; 15: limit plate; 16: ear shaft; 17: long hole; 18: approaching body; 19: bushing; 20: pin hole.

[0014] As shown in the accompanying drawings, a material receiving and transferring device in sampling includes a frame 1, on which a rotating shaft 12 is rotatably installed in the up and down directions. The rotating shaft is driven by a motor, and the motor adopts a servo motor. A reducer 3 is connected to the output shaft of the motor, and a driving gear 4 is fixedly connected to the output shaft of the reducer. A driven gear 13 is fixedly connected to the rotating shaft, and the driven gear is meshed with the driving gear.

[0015] A shaft sleeve 19 is rotatably connected to the rotating shaft 12, a bracket 5 is fixedly connected to the shaft sleeve, a hopper 6 is fixedly connected to the bracket, the upper and lower parts of the hopper are both open, a rotating bottom valve plate 7 is arranged under the hopper, the rotating bottom valve plate is fixedly connected to the rotating shaft through a connecting handle 8, a latch clutch mechanism is installed between the bracket and the connecting handle, the latch clutch mechanism includes a pin hole 20 opened on the connecting handle, a latch 9 is slidably installed up and down on the bracket above the pin hole, the side of the latch is fixedly connected to the ear shaft 16, the driving plate 10 is rotatably connected to the bracket near the middle, a long hole 17 is opened on the driving plate near the front end, the ear shaft is located in the long hole, and the rear end of the driving plate is hinged to the action end of the traction electromagnet. A limit plate 15 is fixedly installed on the bracket, the latch passes through the limit plate, the latch has an elastic limit part, and a reset spring 11 is inserted on the latch between the spring limit part and the limit plate. After the latch is separated from the pin hole, the spring limit part compresses the reset spring toward the limit plate. A proximity body 18 is connected to the latch, and one or two proximity switches inductive to the proximity body are installed on the bracket. Installing one proximity switch can detect whether the latch is inserted into the pin hole, and installing two proximity switches can also detect whether the latch is out of the pin hole.

[0016] When the utility model is used, in the initial state, the latch is located in the pin hole, and the initial position of the hopper is located at the material receiving pipe (above the material receiving belt conveyor). The sampling head collects the sample at a fixed point and rises to the right position. The motor drives the connecting handle to rotate through the latch to drive the bracket to rotate integrally so that the hopper rotates under the sampling head. The sampling head discharges the material into the hopper. The motor drives the connecting handle to rotate through the latch to drive the bracket to rotate integrally to leave the bottom of the sampling head to the initial position. The sampling head continues to sample at the next depth. When the material in the hopper meets the discharge requirements, the hopper rotates to the initial position, and the traction electromagnet drives the driving rod to rotate. During the rotation of the driving rod, the ear shaft slides in the long hole and moves up and down to make the latch disengage from the pin hole. At this time, the motor rotates only to drive the connecting handle to drive the rotating bottom valve plate to rotate. The rotating bottom valve plate rotates to open the bottom surface of the hopper to unload the material. After unloading, the rotating bottom plate valve rotates in the opposite direction to the bottom of the hopper to close it. A complete sample sampling process is completed.

[0017] After describing the implementation mode of the utility model in detail, people familiar with the technology can clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent application. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the scope of the technical solution of the utility model, and the utility model is not limited to the implementation mode of the examples given in the specification.
