Technical Field

[0001] This utility model relates to the field of material handling device technology, and in particular to an automatic material handling machine. Background Technology

[0002] Cement, as an indispensable basic material in construction projects, directly affects the safety and durability of buildings. Therefore, strict control over cement quality is crucial. Cement sampling and testing is a key step in cement quality control, aiming to assess whether the physical properties, chemical composition, and other indicators of cement meet relevant standards through testing.

[0003] Traditional sampling and testing methods typically involve manual sampling, which has the following drawbacks:

[0004] 1. Insufficient representativeness of samples: Manual sampling is easily affected by the subjective factors of the operator, such as sampling location and sample quantity, making it difficult to ensure the representativeness of the samples, which in turn affects the accuracy of the test results.

[0005] 2. Low sampling efficiency: Manual sampling requires a lot of manpower and time, especially in large-scale projects, making it difficult to meet the needs of efficient sampling.

[0006] 3. Samples are susceptible to contamination: During manual sampling, samples are easily contaminated by the external environment, such as dust and moisture in the air, which can affect the reliability of the test results.

[0007] Currently, there is no automatic material handling machine suitable for cement sampling. Utility Model Content

These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this invention, first information may also be referred to as second information, and similarly, second information may also be referred to as first information.

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0045] See Figures 1 to 6 The automatic material handling machine shown includes a cylinder 100, a material handling device 200, a material receiving device 300, a material conveying channel 400, and a drive device 500.

[0046] A cylindrical body 100 is located at the cement discharge port; in this embodiment, the cylindrical body 100 has a cylindrical structure. A material-collecting device 200 is located inside the cylindrical body 100. A material-receiving device 300 is located outside the cylindrical body 100. One end of the material transfer channel 400 serves as a material inlet 410 extending into the cylindrical body, corresponding to the discharge position of the material-collecting device 200. The other end of the material transfer channel 400 serves as a material outlet 420, corresponding to the material-receiving device 300. The material inlet 410 has a flared structure. A driving device 500 is connected to the material-collecting device 200, and the driving device 500 drives the material-collecting device 200 to complete the discharge action, delivering the cement sample to the material inlet 410 of the material transfer channel 400.

[0047] In this embodiment, the material handling device 200 includes a first rotating shaft 210 extending through the cylinder at both ends. A sealing structure 211 is provided at the contact point between the first rotating shaft 210 and the cylinder, and the sealing structure 211 can be a shaft seal assembly. A collecting hopper 220 and a blocking part 230 are provided at the portion of the first rotating shaft 210 located inside the cylinder 100. The blocking part 230 blocks the material collection port 410 when collecting cement samples. To facilitate efficient collection of cement material by the collecting hopper 220, a guide groove 240 is provided inside the cylinder 100 to guide the material to the collecting hopper 220.

[0048] The driving device 500 includes a sleeve 510 and a limiting structure 520. The sleeve 510 is disposed on the outer wall of the cylinder 100 and engages with the first end of the first rotating shaft 210. A compression spring 530 and a rotation guide component 540, both engaging with the first rotating shaft 210, are disposed inside the sleeve 510. Preferably, the first end of the first rotating shaft 210 has a spring groove 531, the compression spring 530 is disposed within the spring groove 531, the rotation guide component 540 is helically fixed to the outer wall of the first rotating shaft 210, and a guide groove 541, engaging with the rotation guide component 540, is disposed inside the sleeve 510. A detachable pressure cap 511 is provided at the end of the sleeve 510 for easy assembly of the compression spring 530.

[0049] The limiting structure 520 is located on the outside of the cylinder 100 and cooperates with the second end of the first rotating shaft 210. The limiting structure 520, the compression spring 530, and the rotation guide component 540 cooperate to allow the first rotating shaft 210 to rotate while moving axially. When the limiting structure 520 is in the initial position, the first rotating shaft 210 is in the sampling position. At this time, the collecting hopper 220 faces upward and the blocking part 230 blocks the collecting port 410. When the limiting structure 520 is in the discharging position, the first rotating shaft 210 is in the discharging position. At this time, the collecting hopper 220 moves above the collecting port 410 and flips downward to pour the collected material into the collecting port 410. When the limiting structure 520 resets from the discharging position back to the initial position, the first rotating shaft 210 is in the sampling position. At this time, the collecting hopper 220 faces upward and the blocking part 230 blocks the collecting port 410.

[0050] In this embodiment, the limiting structure 520 includes a chuck 521 and a limiting plate 522. The chuck 521 is engaged with the second end of the first rotating shaft 210 via a bearing 521a. The limiting plate 522 engages with a groove 521b on the chuck 521, and the limiting plate 522 can move horizontally along the axial direction of the first rotating shaft 210. Preferably, the limiting plate 522 is connected to the linkage device 600, and the limiting plate 522 is a cam structure. The linkage device 600 includes a motor 610, the output end of which is connected to the second rotating shaft 620. The second rotating shaft 620 is perpendicularly connected to the cam structure, and the motor 610 is mounted on a motor mount 611. The receiving device 300 includes a circular receiving tray 310, which is divided into several equally divided sector-shaped receiving slots 311. The circular receiving tray 310 is rotatably mounted on a receiving base 330 via a rotating shaft 320. A driven gear 321 is mounted on the rotating shaft 320, and a driving gear 621 that meshes with the driven gear 321 is mounted on a second rotating shaft 620. The gear ratio between the driven gear 321 and the driving gear 621 can be determined based on the number of sector-shaped receiving slots 311 on the circular receiving tray 310 and the stroke of the first rotating shaft 210. For example, in this embodiment, the circular receiving tray 310 is divided into four equally divided sector-shaped receiving slots 311. The gear ratio between the driven gear 321 and the driving gear 621 can be set to 4:1. When the driving gear 621 rotates one revolution, the cam structure rotates one revolution, and the first rotating shaft 210 completes one reciprocating movement and reset, thus completing one receiving cycle for one sector-shaped receiving slot 311. Therefore, when the drive gear 621 rotates four times, it can complete the collection of materials in the four sector-shaped collection troughs 311. The method of using multiple sector-shaped collection troughs 311 to collect materials for comprehensive evaluation of the sampled materials is more accurate than the method of testing only once.

[0051] An indicator light 101 is installed on the outer wall of the cylinder 100, and a material sensor 311a is installed at the bottom of the fan-shaped receiving trough 311. The indicator light 101 and the material sensor 311a are connected to the control device. Therefore, when the receiving of one of the fan-shaped receiving troughs 311 is completed, the material sensor 311a senses the weight, the indicator light 101 displays, and preparation for the next sampling begins. When all four fan-shaped receiving troughs 311 have completed receiving, all four indicator lights 101 will display "completed".

[0052] The working process of this utility model is as follows:

[0053] In the initial state, the farthest point 522a of the cam structure is located in the slot 521b of the chuck 521, while the first rotating shaft 210 is in its initial position. At this time, the hopper 220 faces upwards, and the blocking part 230 blocks the feeding port 410. When material feeding begins, the motor 610 operates. During the first half-turn rotation of the drive gear 621, the farthest point 522a of the cam structure rotates to its farthest point. At this time, the closest point 522b of the cam structure is located in the slot 521b of the chuck 521. During this process, due to the cooperation of the chuck 521, the compression spring 530, and the rotating guide component 540, the first rotating shaft 210 moves towards the cam structure while simultaneously rotating. Figures 7 to 10 As shown, the blocking part 230 gradually stops blocking the material inlet 410. During the rotation of the collecting hopper 220, the material falls into the collecting hopper 410 until the collecting hopper 220 completes a 180° rotation to complete the complete material unloading process. At this time, one of the fan-shaped receiving troughs 311 has completed its material collection. The material sensor 311a senses the weight, and the indicator light 101 displays that it is ready to enter the next sampling preparation. During the process of the drive gear 621 rotating half a turn, the farthest point 522a of the cam structure moves to the nearest end. At this time, the farthest point 522a of the cam structure is located in the slot 521b of the chuck 521. During this process, the first rotating shaft 210 completes its reset and enters the next sampling preparation.

[0054] This invention enables automatic online sampling without the need for manual sampling, overcoming the problems of insufficient sample representativeness, low sampling efficiency, and easy sample contamination caused by manual sampling. It improves sampling efficiency, ensures sampling quality, and provides a more reliable technical guarantee for cement quality control.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0056] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0057] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
