[0002] Sand mold sampling refers to selecting a representative part from the prepared sand mold according to certain specifications and requirements during the casting production process, thereby ensuring the quality of the casting. Manual sampling is used to collect samples from the limestone pile in the stockpile for quality inspection of the limestone. This method has the disadvantages of being one-sided in terms of sample representativeness, posing certain safety hazards, and increasing labor intensity.

[0003] A sand mold sample collection device refers to a specialized tool and equipment used to collect representative sand samples during the sampling process to reduce and avoid manual labor costs. This is used to prepare samples and perform performance testing. The purpose is to conduct efficient and accurate analysis of the selected samples. However, in existing sand mold sample collection devices, the terrain in the sampling area is uneven, requiring the conveyor path to be flexible in turning or adjusting its tilt angle. However, the fixed-angle conveyor structure cannot avoid obstacles or be flexibly adjusted, causing the device to interfere with the site environment and even fail to accurately reach the designated sampling point, thus reducing sampling efficiency.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the device uses a support frame as a framework. A motor drives roller one, which in turn drives roller two via a belt to form a material conveying path. An electric push rod pushes the adjusting frame, causing the baffle to align with the material flow. The support plate stabilizes the adjusting frame, receiving the material to complete the initial collection and guiding the material into the sampling area to prevent blockage.

The guiding component at the top of the rotating shaft one optimizes the guiding effect: the connecting frame rotates synchronously with it, and the rotating shaft two at its left and right ends drives the guide plate to rotate flexibly. The guide plate can adapt to the sample conveying path and position adjustment angle, guide and limit the sample, avoid deviation, and ensure smooth sampling. Attached Figure Description

Specifically, the fixing mechanism 3 plays a key role in fixing and guiding in the sand mold sample sampling device, working together to ensure sampling accuracy. Fixing frame 301 is fixed to the right side of the inner wall of the support frame 1, providing support for the fixing mechanism 3. The rotating shaft 302 in the middle of its inner side can rotate flexibly, making it easy to adjust the angle of the component. The fixing frame 303 at the bottom of the outer wall of the rotating shaft 302 is locked by screw 304 and nut 305. When tightened, the rotation of the rotating shaft 302 is restricted, ensuring the stability of the component position during sampling. When loosened, it can rotate freely to adjust the angle. The guide component 306 at the top of the outer wall of the rotating shaft 302 optimizes the sampling guidance. The connecting frame 3061 is fixed to the top of the rotating shaft 302 and rotates synchronously.

[0020] Reference Figure 1 , Figure 2 and Figure 3 A fixing ring 7 passes through the middle of the outer side of the rotating shaft 302. Bolts 6 are threaded on both the left and right sides of the outer wall of the fixing ring 7. Adjusting plates 8 are fixedly connected to the bottom of the outer side of the support frame 1.

Connecting holes 13 are opened around the outer perimeter of the partition plate 12. Specifically, the rotating shaft 302 is positioned by the fixing ring 7 in the middle of the outer side. After the bolts 6 on the left and right sides of the outer wall of the fixing ring 7 are tightened, the rotating shaft 302 can be firmly locked to the associated components to ensure that it does not shift during rotation. The adjusting plate 8 at the bottom of the outer side of the support frame 1 can flexibly adjust the overall height and level of the support frame 1 through multiple screws 9 in the middle of the inner wall to adapt to different working scenarios. The connecting rods 10 on the front and rear sides of the outer wall of the roller 204 cooperate with the bearing 11 on the left side to keep the roller 204 stable during rotation and reduce friction, ensuring the smooth transmission of the belt 203 in the transmission mechanism 2. The partition 12 on the top left side of the support frame 1 can separate the left side area of ​​the device to prevent sand samples from scattering to other components during sampling. The connecting holes 13 around the outer side of the partition 12 provide installation interfaces for docking with other auxiliary components, which facilitates the expansion of the device's functions.

[0021] Working principle: Roller 1 202 rotates, driving roller 2 204 synchronously via belt 203, forming the basic path for material conveying. When belt 203 transports materials, the sampling component 205 located on the top right side of support frame 1 begins to collect samples: slide rail 2051 provides a sliding track for slide plate 2056, electric push rod 2053 pushes adjustment frame 2054 to adjust its position, so that baffle 2055 accurately aligns with the material flow, and support plate 2052 provides stable support for adjustment frame 2054. The initial sample collection is completed by receiving materials. The fixing mechanism 3 achieves the functions of guiding and unblocking. Fixing frame 1 301 is fixed to the right side of the inner wall of support frame 1, and its inner rotating shaft 1 302 can rotate flexibly. With the screw 1 304 and nut 305 on fixing frame 2 303, the angle is locked to ensure the accurate position of guide component 306. Connecting frame 3061 rotates with rotating shaft 1 Rotation of 302 drives the rotating shaft 3062 and guide plate 3063 to adjust their angles, guiding the material smoothly into the sampling area and avoiding blockage. The device uses a cylinder 5 with a stroke of 350mm as the power source, driven by compressed air, to work with the sampling component 205 to complete the production of the sampling plate. The control system uses a time control relay from 1 second to 99 minutes, which can accurately adjust the sampling time and interval according to actual production. By controlling the start and stop rhythm of the motor 201, electric push rod 2053 and cylinder 5, the sampling frequency and sampling amount of each sampling point can be effectively controlled. Finally, the collected sample falls into the sample bucket 4 at the bottom of the inner wall of the support frame 1, completing the sampling process. Through the combination of mechanical structure and electrical control system, the device realizes automatic sample reception, transmission and collection during material transfer, adapting to limestone sampling needs and having flexible time adjustment capabilities, ensuring the accuracy and efficiency of sampling. The fixing mechanism 3 plays a crucial role in fixing and guiding the sand mold sample collection device. The coordinated operation of all components ensures the accuracy of the sampling process. Fixing frame 301, as the basic structure, is fixed to the right side of the inner wall of the support frame 1, providing stable support for the entire fixing mechanism 3. The rotating shaft 302, rotatably connected to its inner center, can rotate flexibly, providing a basis for subsequent angle adjustments. The fixing frame 303 at the bottom of the outer wall of the rotating shaft 302 is locked in place by a screw 304 and a nut 305. When it is necessary to fix the position of the rotating shaft 302, tightening the screw 304 and reinforcing it with the nut 305 restricts rotation. The rotation of the rotating shaft 302 ensures the stability of the relevant components during sampling. After loosening the screws and nuts 305, the rotating shaft 302 can rotate freely to adjust the angle. The guide assembly 306 on the top of the outer wall of the rotating shaft 302 further optimizes the sampling guidance effect. The connecting frame 3061 is fixed to the top of the rotating shaft 302 and rotates synchronously with it. The rotating shafts 3062 on the left and right ends of its outer wall can drive the guide plate 3063 to rotate flexibly. The guide plate 3063 can be angled according to the conveying path and position of the sand mold sample, which guides and limits the sample, prevents the sample from deviating during conveying, and ensures the smooth progress of the sampling operation.
