Description

Technical Field

[0001] This utility model belongs to the technical field of grain storage equipment, and specifically relates to a portable deep sampler for in-warehouse pipe laying work such as grain silo sampling. Background Technology

[0002] As a preliminary step for sampling bulk materials, the installation of pipes in grain warehouses typically requires the pipes to be arranged according to the different types of grains and the size of the grain warehouse, with fixed spacing and height requirements. Electric samplers are then added to achieve the operational goals. With the development of warehouse construction technology, the storage depth of grain warehouses in my country is also increasing. Traditional manual pipe installation is not only inefficient and limited in depth, making it impossible to meet the requirements for sampling deep grain piles, but also poses certain safety hazards because the operation needs to be carried out in a relatively closed environment.

[0003] To address the aforementioned issues, existing technology provides an automatic deep grain pile tube lowering device, which mainly includes a drive unit and a clamping box. The drive unit moves the sampling box downwards, and the clamping box lowers the sampling tube or sleeve until it reaches the lowest point. Then, the movable jaws of the clamping box release the sleeve, and the drive unit drives the sampling box upwards. The above steps are repeated until the predetermined depth is reached, improving the tube lowering efficiency. However, since the clamping box moves the movable jaws via a first cylinder and a second cylinder, an additional air pump is required for power supply on this tube lowering device. Therefore, the device is large in size and inconvenient to move. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a portable deep sampling device. The technical problem this invention aims to solve is: how to improve the portability of the tube-laying equipment.

[0005] The objective of this utility model can be achieved through the following technical solution: A portable deep sampling device includes a substrate and a lower tube body. A clamping mechanism and a control box are respectively provided on both sides of the lower tube body. The lower tube body includes a sleeve and a driving assembly. The driving assembly is arranged perpendicularly to the substrate and can drive the sleeve to move up and down. The clamping mechanism, the lower tube body and the control box are located on the same axis and are arranged sequentially along the length of the substrate. A roller is provided at one end of the substrate with the control box. When the insertion end of the sleeve is above the substrate, the lower tube body can be moved to any position by the roller.

[0006] This application uses a control box to drive a drive assembly to move a sleeve downwards and insert it into a grain pile for sampling. A clamping mechanism on the substrate ensures that the sleeve does not shift during insertion and allows for easy disassembly and installation of the sleeve. The drive assembly is perpendicular to the substrate to ensure sampling accuracy and prevent shifting due to geometric errors between the drive assembly and the substrate. Furthermore, the clamping mechanism, the lower tube body, and the control box are arranged on the same axis and sequentially along the length of the substrate. This reduces the footprint of the lower tube device and avoids interference with other pipes during installation. Positioning the control box near the rollers shifts the device's center of gravity, allowing the user to easily lift one end and use the rollers to move the device to the desired position, preventing blind spots during sampling. The reduced size and increased rollers enhance the portability of the lower tube device.

[0007] In the aforementioned portable deep sampler, handles are provided at the top and bottom of the substrate, with one handle located on the drive assembly or control box and the other handle located at the other end of the substrate. By providing handles at the bottom and top of the lower tube device, user comfort is improved, and the lower tube device can be raised to accommodate changes in height within the grain silo.

[0008] In the aforementioned portable deep sampler, the drive assembly includes guide rails located on both sides, and the control box is situated between the two guide rails. By placing the control box between the two guide rails of the drive assembly, the footprint is reduced while the lateral rigidity of the drive assembly is improved.

[0009] In the aforementioned portable deep sampling device, a supporting base plate is folded onto the base plate. The supporting base plate is connected to the base plate via a limiter and a hinge. When the supporting base plate is unfolded, it is flush with the base plate. By hinged to the edge of the base plate, a foldable supporting base plate is provided, ensuring portability while increasing the contact area between the device and the top of the grain pile by unfolding the supporting base plate and aligning it with the base plate. This improves sampling stability and prevents the reference plane used for support from tilting during sampling.

[0010] In the aforementioned portable deep sampler, one end of the positioning rod is provided with a positioning pin, which is engaged with the positioning groove.

[0011] In the aforementioned portable deep sampler, the bracket is provided with an installation platform, the support base is connected to a reciprocating positioning rod, the positioning rod is hinged to a hinge, and the positioning rod can be engaged with the positioning groove on the limiter.

[0012] In the aforementioned portable deep sampler, one end of the hinge is hinged to the limiter, and the other end is provided with an elastic element, which abuts against the other end of the positioning rod.

[0013] In the aforementioned portable deep sampler, there are three support base plates, which are respectively hinged to the left and right sides and the front end of the substrate, and the rollers are located at the rear end of the substrate.

[0014] In the aforementioned portable deep sampler, an oxygen concentration sensor is installed on the back of the control box. By installing an oxygen concentration sensor on the back of the control box, changes in oxygen concentration within the grain silo can be detected, thus improving safety during use.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. This application arranges the clamping mechanism, the lower tube body, and the control box on the same axis and sequentially along the length of the substrate. While reducing the footprint of the lower tube device, it also provides rollers and handles on the substrate, enabling it to move to different sampling points, thereby improving the portability of the lower tube device. Furthermore, by placing the control box near the rollers, the center of gravity of the lower tube device is positioned at the rear, making it easier for users to push the lower tube device to the corresponding position using the handle, thus improving the user experience.

[0017] 2. This application provides foldable support base plates on the front and left and right sides of the substrate. While reducing the floor space occupied in the storage state, the support base plates increase the contact area during use, ensuring the stability of the tube lowering device during operation.

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] Example 1

[0026] like Figure 1 As shown, this application includes a substrate 1, rollers 1a disposed on the edge of the substrate 1, and a support base plate 5. There are three support base plates 5, which are respectively located at the front end and the left and right sides of the substrate 1. The rollers 1a are located at the rear end of the substrate 1. The substrate 1 is also provided with a clamping mechanism, a lower tube body 3, and a control box 4. The clamping mechanism, the lower tube body 3, and the control box 4 are disposed on the same axis. The lower tube body 3 includes a drive assembly 3a and a sleeve 3b. The drive assembly 3a is used to drive the sleeve 3b to move up and down. The clamping mechanism 2 is located on the front side of the sleeve 3b, and the control box 4 is located on the rear side of the drive assembly 3a. The drive assembly 3a includes a drive motor 3a1 located at the bottom and a guide rail 3a2. A lower tube support 3c is slidably connected to the guide rail 3a2. The lower tube support 3c is provided with a tube seat 3c1 communicating with the sleeve 3b. A rotary motor 3c2 and a level bubble 3c3 are respectively provided on both sides of the tube seat. The supporting base plate 5 is equipped with a hinge 5a and a positioning rod 5b, the base plate 1 is equipped with a limiter 1b, and the back of the control box 4 is equipped with an oxygen concentration sensor 7, which is used to detect the oxygen content in the grain silo and improve the safety of use.

[0027] It is worth mentioning that the tube seat and the sleeve are connected by bearings, and one end of the rotating motor passes through the lower tube support and is connected to the other end of the sleeve by gears.

[0028] like Figure 2 and Figure 3 As shown, one end of the sleeve 3b of this application passes through the clamping mechanism 2 and the substrate 1. The guide rail 3a2 in the drive assembly 3a is set perpendicular to the substrate 1. The top and bottom of the lower tube device are provided with handles 6, one handle 6 is located at the top of the guide rail 3a2, and the other handle 6 is located below the substrate 1. The drive motor 3a1 in the drive assembly 3a is located below the control box 4 and drives the lower tube support 3c to move up and down through belt drive.

[0029] It is worth mentioning that, such as Figure 3 As shown, the substrate 1 and the support base plate 5 of this application are hinged together by a hinge 5a and a limiter 1b. The hinge 5a and the positioning rod 5b are hinged together by a pin, allowing them to swing. The end of the positioning rod 5b is provided with a positioning pin 5b1, and the limiter 1b is provided with two limiting grooves 1b1. Through the cooperation of the positioning pin 5b1 and the limiting grooves 1b1, the substrate 1 and the support base plate 5 are fixed in the unfolded and folded states of the lower tube device.

[0030] like Figure 4 as well as Figure 5 As shown, the clamping mechanism 2, the lower tube body 3, and the control box 4 are arranged on the same axis and sequentially along the length of the substrate 1. The front and rear ends of the substrate 1 are respectively connected to the support base plate 5 and the roller 1a. The clamping mechanism 2 is located at the end with the support base plate 5, and the control box 4 is located at the end with the roller 1a. It should be noted that before driving the lower tube body 3 to move, the front end with the support base plate 5 is raised.

[0031] This application uses a control box 4 to control a drive motor 3a1, a clamping mechanism 2, and a rotary motor 3c2 above a lower tube support 3c. This drives the sleeve 3b to rotate and move up and down along the guide rail 3a2 in the drive assembly 3a until the end of the sleeve 3b moves to the predetermined sampling point. Then, the grain at the sampling point is sucked out by a sample storage device connected to the fixed tube seat 3c 1 to complete the sampling. In order to avoid the end of the sleeve 3b from being concave during insertion and sample suction, which would cause the substrate 1 to tilt and affect the sampling results, three support base plates 5 are respectively set at the front end and the left and right sides of the substrate 1. The support base plates 5 are placed on the same plane as the substrate 1. By adding support base plates 5, the stability during the sampling process is increased, and the tilting of the substrate 1 during insertion is avoided, which would prevent the sleeve 3b from reaching the predetermined position, thus improving the accuracy of the sleeve 3b during the lower tube process.

[0032] Furthermore, the clamping mechanism 2, the lower tube body 3, and the control box 4 of this application are arranged sequentially along the length of the substrate 1 and are located on the same axis, thereby reducing the footprint of the lower tube device. Rollers 1a are provided on the substrate 1 to facilitate the user in moving the lower tube device to different positions, improving portability. The control box 4 is located at the end of the substrate 1 where the rollers 1a are located, thereby shifting the center of the lower tube device, making it easier for the user to push the lower tube device to move by the handle 6 located on the guide rail 3a2, improving the user experience. In order to adapt to different grain warehouse environments and place it on the surface of the grain pile, this application also provides another handle 6 at the bottom of the substrate 1, and provides a wear-resistant strip below the handle 6 to improve service life.

[0033] It is worth mentioning that a hinge 5a is used as a connecting element between the supporting base plate 5 and the base plate 1 to form a foldable hinged connection. A limiter 1b and a positioning rod 5b are provided on the base plate 1 and the supporting base plate 5 to maintain the folded and unfolded states of the supporting base plate 5 and the base plate 1. Specifically, this embodiment uses a positioning pin 5b1 at one end of the positioning rod 5b and an elastic element at the other end. Since the middle of the positioning rod 5b is hinged to the hinge 5a, and both ends of the elastic element abut against the positioning rod 5b and the hinge 5a respectively, when the elastic element... When one end of the positioning rod 5b is pushed upward, the positioning pin 5b1 engages with one of the limiting grooves 1b1 on the limiter 1b. The user can unlock the positioning rod 5b by pressing the end with the elastic element to engage the positioning pin 5b1 with the other limiting groove 1b1. It should be noted that this embodiment uses a technical solution where the positioning pin 5b1 and the limiter 1b are engaged by a conical surface. As an alternative, a concave-convex fit or other solution can also be used to complete the connection between the positioning pin 5b1 and the limiting groove 1b1. This is common knowledge and will not be elaborated on here.

[0034] In addition, the other end of the sleeve in this application is connected to the fixed pipe seat by a thread. The sleeve is clamped by a clamping mechanism located at the bottom, and the fixed pipe is driven to rotate forward by a rotary motor to make the sleeve and the fixed pipe threaded together, which facilitates the installation of the equipment.
