Description

Technical Field

[0001] The present invention relates to the technical field of soil stabilizer production and processing, and particularly to a dispensing device for soil stabilizers. Background Art

[0002] A soil stabilizer is the abbreviation of a soil solidifying admixture, which is a new type of energy-saving and environmental-friendly engineering material synthesized from a variety of inorganic and organic materials for solidifying various soils. For the soil to be reinforced, according to the physical and chemical properties of the soil, only a certain amount of the stabilizer needs to be incorporated, and after mixing and compaction, the required performance indicators can be achieved.

[0003] Different soil environments have different requirements for the particle size of soil stabilizers. For example, sandy soil has a larger particle size, and larger particle size soil stabilizers are required for filling the internal pores; clay has a smaller particle size, and smaller particle soil stabilizers are required for filling the internal pores. The existing soil stabilizer dispensing equipment cannot screen soil stabilizers with different particle sizes, so the use effect is often poor when facing different soil environments. In addition, in the products obtained by dispensing, the weight of the soil stabilizer often differs from the target weight. The reason is that the output of the soil stabilizer is generally controlled by opening and closing the valve at the discharge port, with a large error, and the soil stabilizer has a certain viscosity and is prone to agglomeration or adhesion in the discharge pipeline, thus resulting in the discharge weight not conforming to the preset weight.

[0004] In view of this, how to provide a device that can screen soil stabilizers and improve the dispensing accuracy is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0057] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0058] As Figures 1-7 shown, the present invention provides a dispensing device for a soil solidifying agent, comprising:

[0059] A dispensing chamber 1, having a feed inlet 101 and a discharge outlet 102, the feed inlet 101 is arranged at the top of the dispensing chamber 1, the discharge outlet 102 is arranged at the bottom of the dispensing chamber 1, and the dispensing chamber 1 is wider at the top and narrower at the bottom, approaching a funnel shape;

[0060] A grading and screening device, communicating with the discharge outlet 102, for screening the soil solidifying agent into coarse-grained soil solidifying agent and fine-grained soil solidifying agent;

[0061] A first diversion pipe 2, a first diversion opening is provided near the discharge outlet 102 of the dispensing chamber 1, one end of the first diversion pipe 2 is communicated with the first diversion opening, and the other end is communicated with a quantitative dispensing mechanism. The grading and screening device intercepts the coarse-grained soil solidifying agent and sends the coarse-grained soil solidifying agent into the quantitative dispensing mechanism through the first diversion pipe 2;

[0062] A discharge pipe 3, communicating with the grading and screening device, the fine-grained soil solidifying agent passes through the grading and screening device and enters the discharge pipe 3, and a second diversion opening is provided at the bottom of the discharge pipe 3;

[0063] A second diversion pipe 4, one end is communicated with the second diversion opening, and the other end is communicated with another quantitative dispensing mechanism. The fine-grained soil solidifying agent is sent into another quantitative dispensing mechanism through the second diversion pipe 4.

[0064] In this embodiment, a crushing mechanism is arranged in the dispensing chamber 1, and the crushing mechanism comprises:

[0065] A crushing motor 5, arranged at the top of the dispensing chamber 1;

[0066] A rotating shaft 6, one end is in transmission connection with the crushing motor 5, the other end extends downward, and a crushing rod 7 is arranged on the rotating shaft 6.

[0067] When the soil solidifying agent is fed into the dispensing chamber 1 from above, the soil solidifying agent can directly contact the crushing rod 7, so that the agglomerated soil solidifying agent is broken into granular form.

[0068] In this embodiment, the grading and screening device comprises:

[0069] A first sieve mesh 8, inclined and arranged at the discharge outlet 102, its lower end is connected to the first diversion opening; a second sieve mesh 9, inclined and arranged in the discharge pipe 3, the first sieve mesh 8 and the second sieve mesh 9 are arranged in parallel, the first sieve mesh 8 is provided with a plurality of first sieve holes penetrating through the upper and lower surfaces, and the second sieve mesh 9 is provided with a plurality of second sieve holes penetrating through the upper and lower surfaces;

[0070] Adjust the screening mesh 10 to form an installation gap between the first screening mesh 8 and the second screening mesh 9. The adjusting screening mesh 10 is arranged in the installation gap and is provided with a plurality of adjusting screening holes penetrating the upper and lower surfaces; a plurality of first screening holes, adjusting screening holes and second screening holes correspond to each other one by one and are connected in sequence. The first screening holes and the second screening holes have the same size, and the aperture of the adjusting screening holes is less than or equal to the aperture of the first screening holes.

[0071] It should be noted that the first screening mesh 8 has a sufficient surface area and the number of screening holes with respect to the volume of the dispensing chamber 1. Therefore, the soil curing agent will not directly enter the first diversion pipe 2 from the first diversion port without being screened.

[0072] Since both the first screening mesh 8 and the second screening mesh 9 are inclined, the adjusting screening mesh 10 is also inclined. The size of the adjusting screening mesh 10 is adapted to the installation gap, and its upper and lower surfaces are in sliding friction with the first screening mesh 8 and the second screening mesh 9. All three screening meshes can be made of a rigid material with a smooth surface. The inclination of the first screening mesh 8, the second screening mesh 9 and the adjusting screening mesh 10 is best at 3° - 8°. If the inclination is too large, the soil curing agent will quickly enter the first diversion pipe 2; if the inclination is too small, the coarse-grained soil curing agent will accumulate at the discharge port 102 of the dispensing chamber 1 and cannot smoothly enter the first diversion pipe 2, which will also affect the screening effect of the soil curing agent above.

[0073] In some other embodiments, multiple sets of grading and screening devices can be arranged from top to bottom, and multiple sets of adjusting screening meshes 10 are also correspondingly arranged. In this way, the soil curing agent can be graded and screened into different particle sizes and input into different quantitative dispensing mechanisms respectively.

[0074] In this embodiment, the grading and screening device further includes:

[0075] A rotating motor 11, an installation plate is arranged on the discharge pipe 3, and the rotating motor 11 is arranged on the installation plate;

[0076] A connecting column 12, vertically arranged on the output end of the rotating motor 11;

[0077] A connecting block 13, one end is connected to the adjusting screening mesh 10, and the other end is connected to the connecting column 12; multiple groups of connecting blocks 13 and adjusting screening meshes 10 are arranged along the circumference of the connecting column 12. The sizes of the adjusting screening holes of multiple groups of adjusting screening meshes 10 are different, and the rotating motor 11 can drive the adjusting screening mesh 10 to move into or out of the installation gap.

[0078] In this embodiment, it further includes:

[0079] An installation frame, the dispensing chamber 1, the discharge pipe 3 and the first driven wheel are all arranged on the installation frame.

[0080] The dispensing chamber 1 and the discharge pipe 3 can actually be regarded as two independent structures. Except for the adjusting screen 10, it is completely hollow between the first screen 8 and the second screen 9. Therefore, the adjusting screen 10 can be smoothly moved in and out.

[0081] In this embodiment, the quantitative dispensing mechanism includes:

[0082] A weighing chassis 14 is arranged on the support platform, and its upper surface corresponds to the first diversion pipe 2 or the second diversion pipe 4, and is used to detect the weight of the soil curing agent on the weighing chassis 14. Side plates 15 are vertically arranged on the left and right sides of the weighing chassis 14;

[0083] A baffle 16 is rotatably arranged on the support platform and is connected to the support platform through a spring. The spring has an elastic tendency to push the baffle 16 towards the vertical state;

[0084] A push plate 17 is arranged at the rear end of the weighing chassis 14 and is connected to a cylinder 18. When the baffle 16 is in the vertical state, the weighing chassis 14, the baffle 16, the side plates 15 and the push plate 17 form a quantitative dispensing chamber, and the coarse-grained soil curing agent or the fine-grained soil curing agent can fall into the dispensing chamber and be located on the weighing chassis 14.

[0085] In this embodiment, electric control valves 19 are arranged on the first diversion pipe 2 and the second diversion pipe 4. The electric control valves 19 are respectively arranged near the lower pipe orifices of the first diversion pipe 2 and the second diversion pipe 4. Both the electric control valves 19 and the weighing chassis 14 are electrically connected to the control center.

[0086] In this embodiment, it further includes:

[0087] A receiving hopper 20. The cylinder 18 can push the coarse-grained soil curing agent or the fine-grained soil curing agent through the push plate 17 and rotate the baffle 16 to the horizontal state. The receiving hopper 20 is connected to the baffle 16 in the horizontal state, and the push plate 17 can push the coarse-grained soil curing agent and the fine-grained soil curing agent into the receiving hopper 20;

[0088] A receiving hose 21, one end of which is communicated with the receiving hopper 20, and the other end is communicated with the product packing box 26.

[0089] In this embodiment, it further includes:

[0090] A driving wheel 22 is arranged inside the support platform and is in transmission connection with a first driven wheel through a belt. The first driven wheel is arranged near the receiving hose 21;

[0091] A first cam 23 is coaxially arranged on the first driven wheel;

[0092] The first set of rings 24 is sleeved on the outer side of the material receiving hose 21. The first set of rings 24 is connected to the protruding end of the first cam 23 through the connecting member 25. When the driving wheel 22 rotates, the first cam 23 rotates and drives the first set of rings 24 to reciprocate, and the first set of rings 24 collides with the material receiving hose 21.

[0093] In this embodiment, the first diversion pipe 2 and the second diversion pipe 4 are hoses, and further include:

[0094] The second driven wheels are respectively arranged close to the first diversion pipe 2 and the second diversion pipe 4, and the second driven wheels are in transmission connection with the driving wheel 22 through belts;

[0095] The second cams are coaxially arranged on the second driven wheels;

[0096] The second sets of rings are respectively sleeved on the first diversion pipe 2 and the second diversion pipe 4. The second sets of rings are connected to the protruding ends of the second cams. When the driving wheel 22 rotates, the second cams rotate and drive the second sets of rings to reciprocate, and the second sets of rings respectively collide with the first diversion pipe 2 and the second diversion pipe 4 (the second driven wheels, the second cams and the second sets of rings are not shown in the figure).

[0097] The specific working process is as follows:

[0098] The soil stabilizer enters the sub-packaging chamber 1 from the feed inlet 101. Under the action of the crushing rod 7, the agglomerated soil stabilizer is broken into granular form. The soil stabilizer moves downward along the sub-packaging chamber 1. When it moves to the discharge port 102, the coarse-grained soil stabilizer is intercepted, and the fine-grained soil stabilizer sequentially passes through the first sieve holes, the adjustment sieve holes and the second sieve holes and enters the discharge pipe 3.

[0099] The coarse-grained soil stabilizer enters the quantitative sub-packaging mechanism through the first diversion pipe 2, and the fine-grained soil stabilizer enters the second diversion pipe 4 from the discharge pipe 3 and then enters another quantitative sub-packaging mechanism. During the process, the driving wheel 22 drives the second driven wheels and the second cams to rotate, and periodically collides with the first diversion pipe 2 and the second diversion pipe 4 to prevent the soil stabilizer from sticking.

[0100] In the quantitative packaging mechanism, the soil stabilizer falls onto the weighing chassis 14. The weighing chassis 14 detects the weight of the soil stabilizer in real time and uploads it to the control center. When the preset weight is reached, the control center closes the electric control valve 19. The cylinder 18 is started. The cylinder 18 pushes the soil stabilizer through the push plate 17 and indirectly pushes the baffle 16, rotating the baffle 16 from the vertical state to the horizontal state against the elastic force of the spring. When the baffle 16 rotates to the horizontal state (in fact, the soil stabilizer can enter the receiving hopper 20 even before reaching the horizontal state), the soil stabilizer is pushed into the receiving hopper 20 and enters the product packing box 26 through the receiving hose 21. During this process, the driving wheel 22 drives the first driven wheel and the first cam 23 to rotate, and periodically collides with the receiving hose 21 to prevent the soil stabilizer from sticking.

[0101] When it is necessary to replace and adjust the sieve mesh 10, just start the rotating motor 11 in the shutdown state and screw the adjusting sieve mesh 10 with a suitable aperture into the installation gap between the first sieve mesh 8 and the second sieve mesh 9.

[0103] The embodiments described above are only for describing the preferred mode of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solution of the present invention should fall within the protection scope determined by the claims of the present invention.
