Abstract
Description
Technical Field
[0001] This utility model belongs to the field of grain and oil inspection technology, and specifically relates to a grain and oil inspection sampling device. Background Technology
[0002] Grain and oil testing sampling devices are used to collect representative samples from grain and oil piles. They are mostly made of corrosion-resistant materials such as stainless steel and include a sampling tube and handle. They can be inserted into the grain pile manually or electrically, and samples are extracted using vacuum, gravity, or mechanical principles, ensuring sample homogeneity and randomness. They are suitable for testing various grains and oils such as wheat and rice, providing a reliable sample basis for quality inspection.
[0003] Chinese patent publication number CN220729720U discloses a grain and oil testing sampling device, including a long rod, a rotating handle, a sample bottle, a bottle cap, a compression spring, and a pull wire. The long rod has graduations and corresponding numbers along its length. The rotating handle is rotatably mounted on the long rod. The bottom of the long rod has an annular groove with an opening at the bottom for placing the sample bottle. The bottle cap is rotatably mounted on a bottle cap mounting bracket. Spring mounting posts are provided between the annular groove on the long rod and the bottle cap mounting bracket, and on the mounting block on the bottle cap. A compression spring is provided between the mounting posts. In the free state, the bottle cap is held in place by the compression spring, always away from the bottle opening. Pressing the rotating handle can cover the bottle opening with the bottle cap. This invention can accurately sample grain and oil at any height within the grain and oil container, ensuring accurate test results. It has a simple structure, is easy to operate, and is also easy to clean.
[0004] However, the current testing and sampling device has the following problems: it cannot test grains and oils at different depths, which has certain limitations. It requires multiple tests, which is inefficient. Therefore, we propose a grain and oil testing and sampling device. Utility Model Content
[0005] The purpose of this invention is to provide a grain and oil testing and sampling device that can solve the problems of the limitations of the existing testing and sampling device in the related technology, which cannot detect grain and oil at different depths, requires multiple tests, and has low efficiency.
[0006] The specific technical solution adopted by this utility model is as follows:
[0007] A grain and oil testing sampling device includes a mobile vehicle. An electric push rod is fixedly connected to the top of the mobile vehicle. A connecting rod is fixedly connected to the telescopic end of the electric push rod. An adjustable sampling device is provided at the bottom of the connecting rod. The adjustable sampling device includes a long rod. The top of the long rod is fixedly connected to the bottom of the connecting rod. A plurality of slotted blocks are fixedly connected to the circumferential surface of the long rod. A sampling cylinder is fixedly connected to the bottom of each of the slotted blocks.
[0008] The adjusting sampling device further includes a sealing piston that is slidably connected to the inner wall of the sampling cylinder. A lifting rod is fixedly connected to the top of the sealing piston. A vertical plate is fixedly connected to the end of several lifting rods away from the sealing piston. A high-position plate is fixedly connected to the side of one vertical plate, and a low-position plate is fixedly connected to the side of another vertical plate. A connecting plate is fixedly connected between the high-position plate and the low-position plate. A pneumatic push rod is fixedly connected to the inner wall of the connecting rod. The telescopic end of the pneumatic push rod is fixedly connected to the top of the connecting plate.
[0009] Several slotted blocks are arranged symmetrically and staggered, and the high-position plate and the low-position plate are located on the same horizontal plane.
[0010] The inner wall of the connecting rod is provided with a striking device, which includes a U-shaped plate. The top of the U-shaped plate is fixedly connected to the inner wall of the connecting rod. A sliding plate is slidably connected to the inner wall of the U-shaped plate. A striking rod is fixedly connected to the side of the sliding plate, and a toggle plate is fixedly connected to the side of the sliding plate.
[0011] The striking device also includes an L-shaped plate fixedly connected to the side of the connecting rod. A driving cylinder is fixedly connected to the inner wall of the L-shaped plate. A vertical rod is fixedly connected to the telescopic end of the driving cylinder. Several baffles are fixedly connected to the side of the vertical rod.
[0012] The sampling cylinder is located on the movement trajectory of the baffle, and a spring is provided between the sliding plate and the U-shaped plate.
[0013] The long rod is located on the movement trajectory of the striking rod, and there is a gap between the striking rod and the connecting plate.
[0014] The technical effects achieved by this utility model are as follows:
[0015] This invention, through adjusting the settings of the sampling device, coordinates the long rod, slotted block, sampling cylinder, sealing piston, lifting rod, vertical plate, high-position plate, low-position plate, connecting plate, and pneumatic push rod. Workers move the mobile cart to the grain and oil drum to be tested, activate the electric push rod, place the adjusting sampling device into the drum, and activate the pneumatic push rod. The upward movement of the pneumatic push rod's extension end causes the connecting plate to move upward, which in turn causes the high-position plate and low-position plate to move upward. This, in turn, causes the vertical plate to move upward, which in turn causes the lifting rod to move upward, which in turn causes the sealing piston to move upward. The upward movement of the sealing piston then causes the sampling cylinder to begin extracting the grain and oil. This avoids the limitations of devices that cannot detect grain and oil at different depths, requiring multiple tests and resulting in low efficiency.
[0016] This invention utilizes a striking device that coordinates an L-shaped plate, a drive cylinder, a vertical rod, a baffle, a U-shaped plate, a sliding plate, a striking rod, and a toggle plate. After the grain and oil enter the sampling cylinder, the drive cylinder is activated. The extension end of the drive cylinder moves, causing the vertical rod to move. The movement of the vertical rod then moves the baffle, blocking the sampling opening of the sampling cylinder and preventing the grain and oil from dripping out. Next, an electric push rod is activated to raise the sampling device to the top of the grain and oil container. Residual grain and oil will remain on the device. The operator pulls the toggle plate, which moves the sliding plate, which in turn moves the striking rod. Simultaneously, a spring is compressed. When the operator releases the spring, it returns to its original position, causing the sliding plate to return to its original position. This, in turn, causes the striking rod to return to its original position. This process repeats, with the striking rod striking the long rod to accelerate the dripping of grain and oil from the device into the grain and oil container, preventing waste.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0025] like Figures 1-5 As shown, a grain and oil inspection sampling device includes a mobile vehicle 1. An electric push rod 2 is fixedly connected to the top of the mobile vehicle 1. A connecting rod 3 is fixedly connected to the telescopic end of the electric push rod 2. An adjusting sampling device 4 is provided at the bottom of the connecting rod 3. The adjusting sampling device 4 includes a long rod 41. The top of the long rod 41 is fixedly connected to the bottom of the connecting rod 3. Several slotted blocks 42 are fixedly connected to the circumferential surface of the long rod 41. A sampling cylinder 43 is fixedly connected to the bottom of each of the slotted blocks 42. The principle of the sampling cylinder 43 is similar to that of a syringe.
[0026] The adjusting sampling device 4 also includes a sealing piston 44 that is slidably connected to the inner wall of the sampling cylinder 43. A lifting rod 45 is fixedly connected to the top of the sealing piston 44. The ends of several lifting rods 45 away from the sealing piston 44 are fixedly connected to the same vertical plate 46. A high plate 47 is fixedly connected to the side of one vertical plate 46, and a low plate 48 is fixedly connected to the side of another vertical plate 46. A connecting plate 49 is fixedly connected between the high plate 47 and the low plate 48. A pneumatic push rod 410 is fixedly connected to the inner wall of the connecting rod 3. The telescopic end of the pneumatic push rod 410 is fixedly connected to the top of the connecting plate 49.
[0027] Several slotted blocks 42 are symmetrically and staggered to extract grain and oil at different depths for testing. The high-level plate 47 and the low-level plate 48 are located on the same horizontal plane.
[0028] Based on the above structure, the staff moves the mobile vehicle 1 to the grain and oil barrel that needs to be tested, starts the electric push rod 2, puts the adjusting sampling device 3 into the grain and oil barrel, starts the pneumatic push rod 410, and the telescopic end of the pneumatic push rod 410 moves upward, which drives the connecting plate 49 to move upward. The upward movement of the connecting plate 49 drives the high plate 47 and the low plate 48 to move upward. The upward movement of the high plate 47 and the low plate 48 drives the vertical plate 46 to move upward. The upward movement of the vertical plate 46 drives the lifting rod 45 to move upward. The upward movement of the lifting rod 45 drives the sealing piston 44 to move upward. The upward movement of the sealing piston 44 causes the sampling cylinder 43 to start extracting grain and oil. This avoids the limitation that the device cannot detect grain and oil at different depths, which requires multiple tests and is too inefficient.
[0029] like Figures 1-5 As shown, the inner wall of the connecting rod 3 is provided with a striking device 5, which includes a U-shaped plate 55. The top of the U-shaped plate 55 is fixedly connected to the inner wall of the connecting rod 3. A sliding plate 56 is slidably connected to the inner wall of the U-shaped plate 55. A striking rod 57 is fixedly connected to the side of the sliding plate 56. A toggle plate 58 is fixedly connected to the side of the sliding plate 56.
[0030] The striking device 5 also includes an L-shaped plate 51 fixedly connected to the side of the connecting rod 3. A driving cylinder 52 is fixedly connected to the inner wall of the L-shaped plate 51. A vertical rod 53 is fixedly connected to the telescopic end of the driving cylinder 52. Several baffles 54 are fixedly connected to the side of the vertical rod 53.
[0031] The sampling cylinder 43 is located on the movement trajectory of the baffle 54. The baffle 54 can block the sampling cylinder 43 to prevent the grain and oil from dripping. A spring is provided between the slide plate 56 and the U-shaped plate 55 for the slide plate 56 to reset and enhance the striking effect of the striking rod 57.
[0032] The long rod 41 is located on the movement trajectory of the striking rod 57, which can make the long rod 41 vibrate and accelerate the dripping of grain and oil into the oil drum. There is a gap between the striking rod 57 and the connecting plate 49 to avoid movement interference and damage to the parts.
[0033] According to the above structure, after the grain and oil enter the sampling cylinder 43, the drive cylinder 52 is activated. The extension end of the drive cylinder 52 moves, which drives the vertical rod 53 to move. The movement of the vertical rod 53 drives the baffle 54 to move. The movement of the baffle 54 blocks the sampling port of the sampling cylinder 43, preventing the grain and oil from dripping from the sampling cylinder 43. Then, the electric push rod 2 is activated to raise the adjusting sampling device 3 to the top of the grain and oil barrel. There will be residual grain and oil on the entire device. The operator pulls the actuating plate 58. The movement of the actuating plate 58 drives the sliding plate 56 to move. The movement of the sliding plate 56 drives the striking rod 57 to move. At the same time, the spring is compressed. When the operator releases his hand, the spring returns to its original position through its own elasticity, thereby driving the sliding plate 56 to return to its original position. The return of the sliding plate 56 drives the striking rod 57 to return to its original position. This process is repeated. The striking rod 57 strikes the long rod 41 to accelerate the dripping of grain and oil on the device into the grain and oil barrel, thus avoiding waste of grain and oil.
[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
