Description

Technical Field

[0001] The utility model relates to the technical field of geotechnical testing equipment, in particular to soil hammering equipment. Background Art

[0002] Before the start of geotechnical physical, hydraulic and mechanical tests, disturbed soil (silt or clay) samples need to be prepared. After the lumps or blocks of disturbed soil samples are air-dried, they are crushed on a rubber plate with a wooden roller. The crushing should not destroy the natural particles of the soil. Then, according to the number of soil samples required for the test, the crushed soil samples are sieved. Among them, the physical test soil samples are sieved with a 0.5mm sieve, the hydraulic and mechanical test soil samples are sieved with a 2mm sieve, and the compaction test soil samples are sieved with a 5mm sieve. The current preparation of disturbed soil (silt, clay) samples relies entirely on manual preparation. Due to the large test volume of some geotechnical tests, manual preparation of soil samples is not only time-consuming, but also causes a lot of dust and uneven force, which may cause the natural particles of the soil to be destroyed, affecting the accuracy of the test results. Therefore, automatic hammering devices are often used to hammer soil.

[0003] For example, the patent with announcement number CN214584384U, with announcement date of 2021-11-02, discloses a fully automatic test model soil hammering device, including a base, a vertical pole and a handle. The lower end of the vertical pole is fixed to the center of the base, and the middle part of the handle is fixed to the upper end of the vertical pole. A spiral sleeve is mounted on the vertical pole, and a spiral groove and a vertical groove are provided on the outer surface of the spiral sleeve. The two ends of the vertical groove and the spiral groove are connected respectively. The upper end of the spiral sleeve is connected to the motor through a transmission mechanism. The motor is provided with a control system. The control system, motor and transmission mechanism are all installed on the handle; a C-shaped sleeve is mounted on the spiral sleeve, and the lower end of the C-shaped sleeve is fixed to the base. A heavy hammer is mounted on the C-shaped sleeve, and a guide block is provided in the mounting hole of the heavy hammer. The guide block is connected to the heavy hammer through a pin shaft, and the guide block is rotatably connected to the pin shaft, and the pin shaft is fixed to the heavy hammer; the guide block passes through the opening of the C-shaped sleeve and is slidably assembled in the vertical groove and the spiral groove. The utility model can accurately and quickly complete the production of model soil and can reduce labor intensity.

[0004] The shortcomings of existing soil hammering devices, including the above-mentioned patents, are that existing soil hammering equipment usually alternates between hammering and screening, that is, after hammering to a certain extent, the disturbed soil that meets the requirements is screened out, and the remaining disturbed soil continues to be hammered to avoid excessive hammering of the disturbed soil. The screening of the disturbed soil is completely manual, which is inconvenient to operate and has low efficiency. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a soil hammering and soil making device which is convenient for screening and has high soil hammering efficiency.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solution: a soil hammering equipment, including a bracket, a filter cartridge assembly arranged on the bracket and rotatable along its own axis, a supporting platform arranged in the filter cartridge assembly and rotatable with the filter cartridge assembly, and a hammering assembly arranged in the filter cartridge assembly for hammering the soil sample on the supporting platform.

[0007] Furthermore, it also includes a protective shell covering the circumference of the filter cartridge assembly and a material receiving hopper arranged below the filter cartridge assembly, and the material receiving hopper is connected to the protective shell.

[0008] Furthermore, the filter cartridge assembly includes a filter cartridge and two mounting plates respectively disposed at both ends of the filter cartridge and rotatably engaged with the filter cartridge.

[0009] Furthermore, a feeding port is provided on one of the mounting plates, and a protective door is provided on the feeding port.

[0010] Furthermore, the bracket is provided with four support wheels respectively located on both sides of the filter cartridge, and each of the support wheels is against the filter cartridge, and any of the support wheels can be driven to rotate by a driving member and drive the filter cartridge to rotate.

[0011] Furthermore, the supporting platform is consistent with the length of the filter cartridge, and a first linear driver is provided between the two mounting plates, and the hammer assembly is provided on the moving end of the first linear driver.

[0012] Furthermore, the hammer assembly includes a second linear drive and a hammer head arranged at the moving end of the second linear drive.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] See also Figure 1 、 2 .

[0024] The utility model discloses a soil-making equipment for hammering soil, comprising a bracket 1, a filter cartridge assembly 2 which is arranged on the bracket 1 and can rotate along its own axis, a supporting platform 3 which is arranged in the filter cartridge assembly 2 and can rotate with the filter cartridge assembly 2, and a hammering assembly 4 which is arranged in the filter cartridge assembly 2 and is used to hammer the soil sample on the supporting platform 3.

[0025] The soil hammering equipment of the present invention installs a bearing platform 3 in the filter cartridge assembly 2, and installs the hammering assembly 4 inside the filter cartridge assembly 2. After the soil sample is preliminarily hammered on the bearing platform 3, the soil sample can be screened when the filter cartridge assembly 2 rotates. The soil sample processing efficiency is high, and since the soil sample is screened by the rotation of the filter cartridge assembly 2, the filter cartridge assembly 2 is not easy to be blocked.

[0026] In this embodiment, see Figure 3, further comprising a protective shell 5 circumferentially covering the filter cartridge assembly 2 and a material receiving hopper 6 disposed below the filter cartridge assembly 2, the material receiving hopper 6 being in communication with the protective shell 5. This design effectively prevents dust from escaping during the hammering of the soil sample through the protective shell 5, and the material receiving hopper 6 collects and flows the soil sample sieved by the filter cartridge assembly 2 for easy collection. Furthermore, the protective shell 5 can be provided only on both sides of the filter cartridge assembly 2 at a lower circumferential position, or can completely enclose the filter cartridge assembly 2.

[0027] In this embodiment, see Figure 1 The filter cartridge assembly 2 includes a filter cartridge 201 and two mounting plates 202 disposed at both ends of the filter cartridge 201 and rotatably engaged with the filter cartridge 201. With this design, the mounting plates 202 connect the filter cartridge 201 to the bracket 1 and provide a mounting location for the filter cartridge 201. Connecting rings 2011 are disposed on both sides of the filter cartridge 201, and both mounting plates 202 are provided with annular notches 2022 rotatably engaged with the connecting rings 2011.

[0028] In this embodiment, see Figure 3 A feeding port 2021 is provided on one of the mounting plates 202, and a protective door 7 is provided on the feeding port 2021. This design prevents the soil sample from being impacted and flying out of the filter cartridge 201 when hammering. In addition, a glass is installed in the middle of the protective door 7, so that the hammering process of the soil sample can be observed through the glass.

[0029] In this embodiment, see Figure 1 The bracket 1 is also provided with four support wheels 8, one on each side of the filter cartridge 201, and each support wheel 8 abuts against the filter cartridge 201. Any of the support wheels 8 can be driven to rotate by a driving member and drive the filter cartridge 201 to rotate. This design supports the filter cartridge 201 by contacting the circumferential surface of the support wheel 8 with the filter cartridge 201, thereby preventing the connection between the filter cartridge 201 and the mounting plate 202, i.e., the aforementioned connecting ring 2011, from being damaged by vibration during the soil sample hammering process. At the same time, the friction between the support wheel 8 and the filter cartridge 201 allows the support wheel 8 to drive the filter cartridge 201 to rotate.

[0030] And wherein, the support wheels 8 are arranged in a rectangular array on both sides of the two ends of the filter cartridge 201;

[0031] The surface of the outer wall of the filter cartridge 201 in contact with the support wheel 8 is roughened to increase the friction between the support wheel 8 and the filter cartridge 201, thereby ensuring that the filter cartridge 201 is stably driven.

[0032] The driving member may adopt the following structure:

[0033] The motor is mounted on the bracket 1, and the output end of the motor is connected to any support wheel 8 in a transmission manner. A sprocket is coaxially connected to the output shaft of the motor, and another sprocket is coaxially connected to the rotating shaft of the support wheel 8 corresponding to the motor. The two sprockets are connected by a chain transmission so that the motor can drive the corresponding support wheel 8 to rotate.

[0034] In this embodiment, see Figure 2 The carrier platform 3 is the same length as the filter cartridge 201, and a first linear actuator 9 is provided between the two mounting plates 202. The hammer assembly 4 is disposed on the movable end of the first linear actuator 9. This design maximizes the amount of soil sample that can be hammered by the device by increasing the area of ​​the carrier platform 3. Furthermore, the first linear actuator 9 can be a rodless cylinder.

[0035] In this embodiment, see Figure 3 The hammer assembly 4 includes a second linear drive 401 and a hammer head 402 provided at the moving end of the second linear drive 401. This design achieves the hammering effect through the drive of the second linear drive 401, with a simple structure and convenient operation; and the second linear drive 401 can be an electric push rod.

[0036] In this embodiment, see Figure 4 The width of the hammer head 402 is equal to the width of the bearing surface of the bearing platform 3. This design ensures that the soil sample at each location on the bearing surface can be hammered by the hammer head 402.

[0037] In this embodiment, see Figure 3 The filter cartridge assembly 2 further includes a limiting member 203 provided on any of the mounting plates 202, the limiting member 203 including a fixing block 2031 provided on the mounting plate 202, an insertion rod 2032 elastically inserted into the fixing block 2031, and a lever 2033 provided on the insertion rod 2032. The supporting platform 3 is provided with a socket 301 which can be plugged into the insertion rod 2032, and the lever 2033 extends into the filter cartridge 201. The hammer assembly 4 can move the lever 2033 to make the insertion rod 2032 exit the socket 301.

[0038] The inner wall of one side of the filter cartridge 201 corresponding to the limit member 203 is provided with a plurality of spaced wedge-shaped protrusions 10. The wedge-shaped protrusions 10 are continuously arranged along the circumference of the inner wall of the filter cartridge 201, and the arrangement area of ​​the wedge-shaped protrusions 10 is equal to the setting arc of the screen. Within the rotation stroke of the filter cartridge 201, the insertion rod 2032 contacts the wedge-shaped protrusions 10 at intervals to achieve knocking of the filter cartridge 201. With this design, after the hammering assembly 4 hammers the soil sample, the hammer head 402 is moved to push the lever 2033, so that the insertion rod 2032 exits the insertion hole 301, and then the filter cartridge 201 is rotated. During the rotation of the filter cartridge 201, it first contracts along the wedge-shaped protrusion 10, and then recovers when it reaches the highest point of the wedge-shaped protrusion 10, thereby hitting the filter cartridge 201, thereby shaking the filter cartridge 201 and preventing large particles of soil from blocking the filter cartridge 201; and wherein, in order to ensure that the filter cartridge 201 shakes when being struck, the wedge-shaped protrusion 10 is designed to be close to the mesh body of the filter cartridge 201, so that the spring through which the insertion rod 2032 is elastically passed is preferably a spring with a larger elastic coefficient.

[0039] Working principle: When the utility model is in use, the protective door 7 is opened, and the soil sample to be hammered is placed on the supporting platform 3, so that the soil sample can be spread flat on the supporting surface of the supporting platform 3. The protective door 7 is closed, and then the second linear drive 401 and the first linear drive 9 are started. The second linear drive 401 extends and drives the hammer head 402 to move toward the supporting surface to crush the soil sample laid on the supporting surface. The first linear drive 9 cooperates to drive the hammer head 402 to move along the axial direction of the filter cartridge 201, and the position of the hammer head 402 is continuously adjusted so that the soil samples at all places on the supporting surface can be crushed.

[0040] After the soil sample is preliminarily processed, the first linear actuator 9 is used to move the lever 2033, causing the insertion rod 2032 to exit the insertion hole 301. Then, the driving member is activated, driving the corresponding support wheel 8 to rotate. The friction between the support wheel 8 and the filter cartridge 201 drives the filter cartridge 201 to rotate. When the mesh portion of the filter cartridge 201 is aligned with the upper opening of the hopper 6, the portion of the soil sample in the filter cartridge 201 that meets the screening particle size leaks through the screen into the hopper 6.

[0041] When the filter cartridge 201 is driven to rotate, the insertion rod 2032 contacts the wedge-shaped protrusion 10 and is restricted by the wedge-shaped protrusion 10 to continuously jump up and down, causing the filter cartridge 201 to vibrate under the action of the insertion rod 2032, thereby promoting the screening of the soil sample on the filter cartridge 201 and preventing large particles of soil from clogging the screen.

[0042] After the filter cartridge 201 rotates one or more times, the supporting platform 3 is restored to its initial state, i.e., the horizontal state. At this time, the hammer assembly 4 releases the lock on the limiter 203 and re-limits the supporting platform 3. Finally, the remaining soil samples in the filter cartridge 201 are hammered multiple times and sieved according to the above steps until all soil samples meet the test requirements.
