Description

Technical Field

[0001] This utility model relates to the field of drying container technology, and in particular to a drawer-type soil drying box and soil drying equipment. Background Technology

[0002] Currently, geotechnical testing is widely used in engineering and experiments. In geotechnical testing, soil samples usually need to be dried to avoid moisture affecting the properties of the soil samples. In the early days, sun drying was used to dry the soil. This method is time-consuming, and different sun drying methods may lead to differences in the drying effect of the same batch of samples.

[0003] Therefore, soil dryers are currently commonly used to dry soil samples. Existing soil dryers can dry soil quickly and effectively, but they can only dry one type of soil sample at a time. When multiple non-mixable soil samples need to be dried, existing soil dryers require drying each sample separately, which is very time-consuming. Furthermore, different soil samples may remain inside the dryer. If other soil samples are dried directly without cleaning, sample mixing will occur, affecting the test results. Utility Model Content

[0004] The purpose of this invention is to provide a drawer-type soil drying box. By setting up multiple drawers for holding soil samples, it is possible to dry soil samples in multiple drawers simultaneously. The addition of a stirring component ensures that the soil samples in each drawer achieve a better drying effect, greatly reducing the time required to dry different soil samples.

[0005] To achieve the above objectives, this utility model provides a drawer-type soil drying box, including a bellows, a drying chamber inside the bellows, and multiple drawer openings arranged sequentially on the front side of the bellows; each drawer opening corresponds to a drawer, which is slidably inserted into the drying chamber through the drawer opening, and a gap air groove is provided between each pair of adjacent drawers; a stirring assembly is provided inside the drawer; an air inlet and an air outlet are respectively opened on the left and right sides of the bellows, and the air inlet and the air outlet are respectively connected to the drying chamber.

[0006] Preferably, both the air inlet and the air outlet are provided with grilles for adjusting the air volume.

Detailed Implementation

[0021] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0022] In the description of this utility model, it should be understood that the terms "front" and "rear" used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to 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 of this utility model.

[0023] like Figures 1-4 As shown, a preferred embodiment of the present invention provides a drawer-type soil drying box, including a wind box 1, a drying chamber 11 inside the wind box, and multiple drawer openings arranged sequentially on the front side of the wind box 1; each drawer opening corresponds to a drawer 2, which is slidably inserted into the drying chamber 11 through the drawer opening, and a gap air groove is provided between each pair of adjacent drawers 2; a stirring assembly 21 is provided inside the drawer 2; an air inlet 12 and an air outlet 13 are respectively opened on the left and right sides of the wind box 1, and the air inlet 12 and the air outlet 13 are respectively connected to the drying chamber 11.

[0024] Specifically, the air box 1 is placed vertically, with drawer openings on the front side of the air box 1. Preferably, there are two rows of drawer openings to ensure a better drying effect. Each drawer opening corresponds to a drawer 2, which is connected to the drying chamber 11. The drawer 2 is slidably inserted into the drying chamber 11, and the front side of the drawer 2 has a pull groove for easy manual pushing and pulling. The air outlet 13 and air inlet 12 are respectively located on the left and right sides of the air box 1. During drying, the drawer 2 is placed inside the air box 1. The device is equipped with a device for providing drying hot air. The drying hot air enters through the air inlet 12, flows through the gap air channel between the drawers 2, and is discharged through the air outlet 13. The gap air channel between the drawers 2 can increase the air flow and dry the soil sample. The drawer 2 is equipped with a stirring component 21, which turns the soil sample while the drying hot air is drying it, so that the soil sample is in full contact with the drying hot air, improving the drying effect and efficiency.

[0025] The drying chamber 11 is located in the middle of the air box 1, and the drawers 2 are all located inside the drying chamber 11. The electrical equipment is located in the space between the back of the drying chamber 11 and the back of the air box 1. The drying hot air only flows through the interior of the drying chamber 11, so that the drying hot air is fully utilized and does not affect the electrical equipment outside the drying chamber 11, thereby improving the service life of the electrical equipment.

[0026] Furthermore, the passage between the air inlet 12, the air outlet 13 and the drawer 2 is truncated into a frustum shape, which facilitates the diffusion of hot drying air through the gaps between each drawer 2 to dry the soil samples in each drawer 2.

[0027] In addition, the direction of movement of drawer 2 is perpendicular to the front side of bellows 1 and towards the inside of bellows 1, and the direction of flow of dry hot air is perpendicular to the direction of movement of drawer 2.

[0028] By placing various soil samples to be dried into multiple drawers 2 arranged in sequence, and allowing hot air to flow through the gaps between the drawers 2 to dry all the soil samples in the drawers 2 simultaneously, the soil samples in the drawers 2 can achieve a better drying effect, greatly shortening the time required to dry different soil samples.

[0029] Preferably, both the air inlet 12 and the air outlet 13 are provided with a grid plate 14 for adjusting the air volume.

[0030] Specifically, the grid plate 14 is a metal plate with multiple strip-shaped through holes on its surface. The strip-shaped through holes are equipped with blades that can be adjusted to control the amount and direction of airflow entering the device by adjusting the degree of opening and closing of the blades. The grid plate 14 is fixedly attached to the air inlet 12 and the air outlet 13 by mounting grooves.

[0031] like Figure 3 As shown, preferably, the stirring assembly 21 includes a roller 211, the two ends of which are rotatably connected to the side wall of the drawer 2.

[0032] Specifically, the mixing assembly 21 includes multiple rollers 211, which are rotatably connected to the side wall of the drawer 2 via bearings, so that the rollers 211 can rotate along their own central axis. The rotation of the rollers 211 can turn over the soil sample in the drawer 2, thereby improving the drying efficiency.

[0033] Furthermore, the device also includes a drive mechanism 3 located in the bellows 1; the roller 211 extends in the front-back direction, the front end of the roller 211 is rotatably connected to the front side wall of the drawer 2, the rear end of the roller 211 passes through the rear side wall of the drawer 2 and is detachably connected to the power output end of the drive mechanism 3, and the drive mechanism 3 can drive the roller 211 to rotate.

[0034] Specifically, roller 211 is arranged along the front-back direction of drawer 2. One end of roller 211 near the rear side of bellows 1 passes through the rear side wall of drawer 2 and extends a certain distance to form a connecting part. The drive mechanism 3 corresponds one-to-one with roller 211 and is arranged inside the rear side of bellows 1. After the device is started, the drive mechanism 3 is always moving. The connecting part of roller 211 is detachably connected to the power output end of drive mechanism 3. When drawer 2 is placed inside bellows 1, roller 211 is connected to drive mechanism 3, and drive mechanism 3 drives roller 211 to rotate. When drawer 2 is pulled out, roller 211 is not connected to drive mechanism 3, and roller 211 does not rotate.

[0035] Furthermore, multiple drawers 2 are arranged in a rectangular array; the stirring assembly 21 includes two rollers 211, and the driving mechanism 3 includes a track 32 and multiple gears 31 that correspond one-to-one with each roller 211. The rear end of the roller 211 is detachably connected to the gears 31, and the two gears 31 corresponding to each stirring assembly 21 mesh with each other; the track 32 is sleeved on the outer periphery of all gears 31, so that each gear 31 is connected in transmission, and the rotation of the track 32 can drive the gears 31 to rotate.

[0036] Specifically, gears 31 and rollers 211 are arranged in a one-to-one correspondence. Two gears 31 corresponding to rollers 211 in the same drawer 2 mesh with each other to form a gear set 34. The track 32 meshes with the outer periphery of one of the gears 31 in the gear set 34 to drive the two gears 31 in the gear set 34 to rotate synchronously, thereby causing the two rollers 211 in the same drawer 2 to rotate synchronously.

[0037] In addition, the track 32 can also be fitted on the outside of the gear 31 in the same row, which can also drive the gear 31 to drive the roller 211 to rotate.

[0038] The drive mechanism 3 also includes a drive wheel (not shown in the figure), a drive motor, and a tensioning mechanism. The drive wheel is connected to the output shaft of the drive motor and meshes with the track 32. The tensioning mechanism is connected to the track 32 and is used to change the direction of the track 32 to increase the length of the meshing section between the track 32 and the gear 31, thereby increasing the wrap angle of the meshing between the track 32 and the gear 31 and improving the driving force of the track 32 on the gear 31 and the stability of the connection.

[0039] like Figure 2 As shown, the tensioning mechanism can be a tensioning wheel 33. Since the multiple drawers 2 are arranged in a rectangular array, the corresponding gear sets 34 are also arranged in a rectangular array. When the track 32 is fitted around the outer periphery of all the gears 31, a tensioning wheel 33 is provided between any two adjacent gear sets 34 in the extending direction of the track 32. The side of the tensioning wheel 33 connected to the track 32 is located within the quadrilateral area enclosed by the two adjacent gear sets 34, so that the track 32 extends towards the side where the axis of the gear 31 it connects to is located, thereby increasing the length of the meshing section between the track 32 and the gear 31, improving the driving force of the track 32 on the gear 31 and the stability of the connection. Figure 2 In the example, since the rectangular array has two columns and more than two rows, tensioning wheels 33 are not required between the two gear sets 34 in the first row and between the two gear sets 34 in the last row. It should be noted that the connection and tensioning methods between the track 32 and the gears 31 are not limited to the one described above. They can be adjusted and selected based on common track design principles, as long as it ensures stable meshing between the track 32 and the gears 31, enabling the track 32 to drive at least one gear 31 of the gear set 34 to rotate.

[0040] Furthermore, the gear 31 has a slot in the middle. When the drawer 2 is inserted into the bellows 1, the rear end of the roller 211 is inserted into the slot. When the roller 211 is inserted into the slot, the roller 211 can rotate with the gear 31.

[0041] Specifically, the side of gear 31 facing away from drawer 2 has a pivot (not shown in the figure). The pivot is rotatably connected to the rear side of bellows 1 via a bearing, allowing gear 31 to rotate relative to bellows 1. A slot is provided in the center of the side of gear 31 facing drawer 2. The slot may or may not penetrate the pivot, as long as it can connect to roller 211. When drawer 2 is placed into bellows 1, roller 211 is inserted into the slot. When drawer 2 is pulled out of bellows 1, roller 211 disengages from the slot. Preferably, the slot is an elliptical through hole, allowing the connecting part of roller 211 to engage in the slot. The elliptical shape also helps to prevent wear or impact damage to the connecting part of roller 211 when connected to the slot.

[0042] Preferably, ventilation slots 22 are provided on the left and right side walls of drawer 2, and the ventilation slots 22 are located near the top of drawer 2.

[0043] Specifically, ventilation slots 22 are located near the top on the left and right side walls of drawer 2. Ventilation slots 22 are set along the length of drawer 2 and extend horizontally from the front end to the rear end of drawer 2. Dry hot air blown from the side of drawer 2 can enter the interior of drawer 2 through ventilation slots 22, so that the hot air can fully contact the soil sample inside drawer 2, improve air flow, and improve drying efficiency. The soil sample is located near the top of drawer 2 so that the soil sample is not easily blown out by hot air.

[0044] Preferably, the drawer 2 has a baffle 23 inside, and the baffle 23 is arranged along the top opening of the drawer 2.

[0045] Specifically, baffle 23 is located at the edge of the top opening of drawer 2. Baffle 23 is inclined towards the middle of drawer 2, which can cause the soil sample to gather in the middle of drawer 2 when the soil sample is put in, so as to avoid the soil sample accumulating on the sides of drawer 2 and making the stirring component 21 turn over poorly. Baffle 23 can facilitate the drying of soil sample and prevent the soil sample from being blown out from the sides of drawer 2 by hot air. When ventilation slot 22 is opened, the soil sample accumulating in the middle of drawer 2 is not easily blown out from ventilation slot 22.

[0046] Preferably, a slide rail 24 is provided between the drawer 2 and the bellows 1 to provide a sliding guide.

[0047] Specifically, the slide rails 24 are located on both sides of the bottom of the drawer 2 and are set along the length of the drawer 2. The slide rails 24 are slidably connected to the rails inside the drawer opening, making it easy to push the drawer 2 in and out.

[0048] The soil drying equipment includes a hot air blower (not shown in the figure) and a drawer-type soil drying box. The hot air blower has a hot air outlet, which is connected to the air inlet 12.

[0049] Specifically, a hot air dryer located outside the device provides drying hot air. The hot air dryer is connected to the air inlet 12, allowing the drying hot air to enter the device through the air inlet 12 to dry the soil sample. The hot air dryer can also be connected to both the air inlet 12 and the air outlet 13 to heat and dry the air flowing out of the air outlet 13, and then input it back into the device through the air inlet 12 for recycling.

[0050] The working process of this utility model is as follows: pull out drawer 2 from the air box 1, put different soil samples into different drawers 2 respectively, and after the soil samples are placed, push drawer 2 into the air box 1 to fix it; during the process of pushing drawer 2 in, the track always drives gear 31 to rotate. Wait for gear 31 to rotate to a suitable angle, insert the connecting part of roller shaft 211 into the slot in the middle of gear 31, and gear 31 drives roller shaft 211 to rotate, turning over the soil samples; start the external drying hot air generating device, adjust the grid plate 14 to adjust the air volume in this device, and the drying hot air enters this device through the air inlet 12, flows through the drying chamber 11, and enters the interior of each drawer 2 through the gap between drawers 2 and the ventilation groove 22 on the side of drawer 2 to contact the soil samples and flow forward to dry the soil samples, and finally discharges from the air outlet 13.

[0051] After the soil sample is dried, pull out drawer 2. The roller 211 will separate from the gear 31 and stop rotating. Then, take out the dried soil sample.

[0052] In summary, this utility model embodiment provides a drawer-type soil drying box, which, by setting multiple drawers for drying soil samples, can simultaneously dry multiple different types or large quantities of soil samples and achieve a better drying effect, greatly reducing the time required for drying soil; by setting ventilation slots 22 and rollers 211, the drying efficiency and drying effect can be effectively improved.

[0053] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
