DETAILED DESCRIPTION

[0022] In order to clearly illustrate the technical features of the scheme, the following through specific embodiment, the scheme is described.

[0023] For example, Figs. 1-5As shown, the automatic fertilizer timing positioning rotary sampler comprises a controller, a sampling box 3 and a material receiver 4. The sampling box 3 is provided with a feeding hopper 31. The sampling box 3 is internally provided with a rotating turntable 32. The sampling box 3 is provided with a first driving mechanism for driving the rotation of the turntable 32. The top surface of the turntable 32 is circumferentially provided with a plurality of sampling cylinders 34. The discharge port of the feeding hopper 31 corresponds to the sampling cylinders 34. In the embodiment, the feeding hopper 31 is fixedly connected to the top of the sampling box 3, and the feeding hopper 31 is located directly above the sampling cylinders 34, so as to discharge the received fertilizer samples into the sampling cylinders.

[0024] Specifically, the bottom surface of the turntable 32 is circumferentially provided with a plurality of universal wheels 35. In the embodiment, the universal wheels 35 are universal ball wheels. The bottom surface of the turntable 32 is provided with four universal wheels 35. The four universal wheels support the turntable to stably and smoothly rotate on the bottom surface of the sampling box.

[0025] Specifically, the top surface of the turntable 32 is circumferentially provided with a plurality of convex rings 33. The plurality of sampling cylinders 34 are inserted into the plurality of convex rings 33 one by one. In the embodiment, the top surface of the turntable 32 is provided with 24 sampling cylinders and 24 convex rings. The inner diameter of the convex ring 33 and the outer diameter of the sampling cylinder 34 are matched. The sampling cylinders are fixed by the convex rings to avoid the sampling cylinders from being tilted when the turntable rotates.

[0026] Specifically, the first driving mechanism is a driving motor 36. The driving motor 36 is fixedly arranged at the bottom of the sampling box 3. The output end of the driving motor 36 is fixedly connected to the center of the turntable 32. The controller is provided with a first time relay (not shown in the figure) which is signal-connected to the driving motor 36. In the embodiment, the driving motor 36 is a servo motor. The servo motor can perform an angular displacement rotation action in a timing and accurate manner under the control of the first time relay, so as to drive the turntable 32 to rotate by a certain angle to position the sampling cylinders 34. The 24 sampling cylinders are sequentially aligned with the discharge port of the feeding hopper 31 in a timing manner, so as to receive the fertilizer samples in different time periods.

[0027] Preferably, the sampling box 3 is provided with a taking and placing opening 37. A box cover 38 is hingedly arranged on the taking and placing opening 37. In the embodiment, the taking and placing opening 37 is arranged at the top of the sampling box 3. It is more convenient for personnel to take out the sampling cylinders from above the sampling box.

[0028] The material receiver 4 comprises a material receiving hopper 41 and a conveying pipe 42. The material receiving port of the material receiving hopper 41 faces the feeding direction of the fertilizer. A cover plate 43 which can be opened and closed is arranged on the material receiving port. The material receiving hopper 41 is provided with a second driving mechanism for driving the opening and closing of the cover plate 43. One end of the conveying pipe 42 is in communication with the discharge port of the material receiving hopper 41. The other end of the conveying pipe 42 is in communication with the feeding port of the feeding hopper 31.

[0029] In order to facilitate the fixation of the material receiver 4, a support frame 5 is arranged on the ground to support the material receiver 4.

[0030] Specifically, the cover plate 43 is hingedly mounted on the receiving port of the receiving hopper 41, the second driving mechanism is a telescopic cylinder 44, one end of the telescopic cylinder 44 is hingedly connected with the receiving hopper 41, and the other end of the telescopic cylinder 44 is hingedly connected with the cover plate 43. The controller is provided with a second time relay (not shown in the figure) in signal connection with the telescopic cylinder 44. The telescopic cylinder 44 in the embodiment is an electric cylinder, and the electric cylinder is controlled to perform telescopic action at a fixed time through the second time relay, so as to drive the cover plate 43 to rotate around the hinge shaft at a fixed time, and the opening and closing of the receiving port are realized. Since 24 sampling cylinders are arranged, the cover plate is opened and closed once every 1 hour for sampling, so that sampling is realized all day long.

[0031] The controller is used for controlling the first driving mechanism and the second driving mechanism to perform action at a fixed time, and the controller in the embodiment is further provided with a processor, the first time relay and the second time relay are both in signal connection with the processor, and the signals of the first time relay and the second time relay are processed through the processor.

[0032] Working principle: The utility model is used for sampling the finished fertilizer conveyed to the stock bin 1, the upper part of the stock bin 1 is usually provided with a conveying belt 2, and the produced fertilizer is conveyed into the stock bin 1 for storage through the conveying belt 2. When in use, the receiving hopper 41 of the receiving device 4 is arranged at the output end of the conveying belt 2, and the receiving port of the receiving hopper faces the feeding direction of the conveying belt, so that the fertilizer can fall into the receiving hopper 41.

[0033] The cover plate 43 on the receiving hopper 41 is opened and closed at a fixed time through the driving of the second driving mechanism, and the opening interval time of the cover plate 43 can be set through the processor, for example, the cover plate 43 is opened once every 1 hour, and the opening time is 3 seconds. Specifically, when the set time is reached, the telescopic cylinder 44 is controlled to retract through the second time relay, so that the cover plate 43 is rotated to open, the fertilizer enters the receiving hopper 41 and falls into the sampling cylinder 34 in the sampling box 3 through the conveying pipe 42. After the cover plate 43 is opened for 3 seconds, the telescopic cylinder 44 is controlled to extend through the second time relay, so that the cover plate 43 closes the receiving port and stops sampling. In this way, the sampling in a time period is completed.

[0034] Meanwhile, the rotation interval time of the sampling cylinder 34 can be set through the processor, and the rotation interval time of the sampling cylinder 34 should be consistent with the opening interval time of the cover plate 43, that is, the sampling cylinder 34 is rotated once every 1 hour. In order to avoid the rotation of the sampling cylinder when receiving the material, the action time of the sampling cylinder and the cover plate should be interval 15 seconds.

[0035] Since 24 sampling cylinders are arranged in the embodiment, in order to make the 24 sampling cylinders align the discharge port of the feeding hopper 31 in turn, the rotation angle of the rotating disc 42 is 15 degrees each time.

[0036] Specifically, when the cover plate 43 is opened, the fertilizer received by the receiving hopper is all fallen into the sampling cylinder, after 15 seconds, at this time, the first time relay controls the driving motor 36 to rotate, so that the rotating disc 32 rotates 15 degrees, so that the rear sampling cylinder 34 is positioned and aligned with the discharge port of the feeding hopper 31, so as to facilitate receiving the fertilizer of the next period.

[0037] Similarly, 24 samples can be received by 24 sampling cylinders respectively for 24 hours, so that the samples of the day shift and the night shift can be sampled on time. The sampling personnel can randomly take samples from the 24 samples according to the detection requirements, and the production stability of the workshop can be monitored.
