Description

Technical Field

[0001] This invention relates to the field of garden construction equipment technology, specifically to a hydraulic hydroseeding machine for slope garden protection and its hydroseeding and planting method. Background Technology

[0002] With the rapid development of infrastructure construction, large-scale projects such as highways, railways, and water conservancy have generated numerous artificial slopes. If these slopes are not properly treated, they are highly susceptible to soil erosion, slope instability, landslides, and other geological disasters under the combined effects of natural factors (such as rainfall, weathering, and freeze-thaw cycles) and human factors (such as vehicle vibrations and construction disturbances). This not only severely damages the surrounding ecological environment but also threatens the safety of roads, buildings, and the lives and property of people below. Therefore, effective slope protection has become a crucial aspect of engineering construction.

[0003] Chinese patent CN115119572B proposes an energy-saving hydraulic hydroseeding machine that solves the problem of complex mixtures being difficult to fully mix using ordinary mixing devices, especially when the order of material addition is different. Insufficient mixing capacity leads to incomplete dispersion of subsequently added materials, resulting in an unbalanced mixture and areas without seeds or with slow growth during hydroseeding. The machine's spheres lack synapses, and their shape can induce overpressure in the direction of movement, accelerating the mixture on its outer side and creating negative pressure within the mixture in the direction of movement. Since the mixture is practically incompressible, it quickly moves from the overpressure area in front of the mixing mechanism to the negative pressure area behind it, creating a suction or expansion effect. This facilitates structural breakage of the mixture and promotes mixing. Furthermore, in the negative pressure area behind the spheres, sediment in the treatment tank is effectively stripped and stirred up, significantly improving mixing efficiency.

[0004] However, the inclined bottom of the hopper causes some material to remain stuck at the bottom during material mixing. Furthermore, due to the contact surface and the viscosity of the material, the spheres in the mixing process cannot effectively contact the mixed material at the bottom of the hopper in the overpressure and negative pressure zones, thus failing to form sufficient vortex entrainment. This results in the material at the bottom potentially accumulating and clumping. Therefore, a hydraulic hydroseeding machine for slope landscaping protection and its hydroseeding and planting method are proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a hydraulic hydroseeding machine for slope landscaping protection and its hydroseeding and planting method, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hydraulic spraying machine for slope landscaping protection, comprising a mixing chamber, a mounting frame fixedly connected to one side of the mixing chamber, a drive structure installed inside the mounting frame, a rotating central rod rotatably connected inside the mixing chamber, and multiple mixing rods fixedly connected to the outside of the rotating central rod. A first hemisphere is fixedly connected to one end of the multiple mixing rods away from the rotating central rod, a wear-resistant tensile rubber is fixedly connected to one side of the first hemisphere away from the mixing rod, and a second hemisphere is fixedly connected to one side of the wear-resistant tensile rubber away from the first hemisphere. A first electromagnet is installed inside both the first and second hemispheres. The two first electromagnets are used to generate mutual attraction or repulsion after being energized, causing the second hemisphere to continuously move away from and gradually move closer to the first hemisphere.

[0007] Preferably, two second electromagnets are fixedly connected inside the first and second hemispheres. The second electromagnets inside the second and first hemispheres are flush with each other. The two second electromagnets inside the second and first hemispheres are located on both sides of the two first electromagnets, and a central fold is provided on the adjacent side of the two wear-resistant tensile rubbers.

[0008] Preferably, a folded chain mesh is integrally formed at the center of the wear-resistant tensile rubber.

[0009] Preferably, both of the wear-resistant tensile rubbers have multiple metal pull ropes integrally molded inside.

[0010] Preferably, the side of the first hemisphere closest to the second hemisphere is a convex spherical surface, and the side of the second hemisphere closest to the first hemisphere is a concave spherical surface.

[0011] Preferably, the bottom wall of the mixing chamber is integrally formed with a chamber body inclined section.

[0012] Preferably, the bottom wall of the mixing chamber is fixedly connected to multiple sets of bottom electromagnets.

[0013] Preferably, the drive structure includes a large drive motor, which is fixedly connected to the mounting frame. A hydraulic suction pump and a small drive motor are respectively mounted on the mounting frame. One end of the rotating center rod passes through the outer wall of the mixing chamber via a coupling. A connecting rod is installed at the end of the output shaft of the small drive motor. A primary pulley is installed at the end of both the connecting rod and the coupling. The primary pulley outside the connecting rod and the coupling is connected by a primary belt drive. The inlet of the hydraulic suction pump is the same as the outlet of the mixing chamber. Secondary pulleys are installed on the outer side of the output shaft of the hydraulic suction pump and the output shaft of the large drive motor. The two secondary pulleys are connected by a secondary belt drive. The outlet of the hydraulic suction pump is connected to a conveying pipe. The end of the conveying pipe away from the hydraulic suction pump passes through the outer wall of the mounting frame.

[0014] Preferably, a spiral stirring plate is fixedly connected between multiple second hemispheres.

[0015] This invention also provides a method for hydroseeding grass using a hydraulic hydroseeding machine for slope landscaping protection, comprising the following steps: Step 1: Add grass seeds, water-retaining agent, adhesive, and fertilizer to the mixing chamber in the specified proportions, and add water to 80% of the volume to form a mixture. Step 2: A viscosity detector is installed inside the mixing chamber to mix the materials in stages according to their viscosity. When the material viscosity is less than or equal to the preset viscosity value, the first stage begins, and the rotating center rod rotates. When the rotation speed of the rotating center rod reaches the specified value, the first electromagnet is periodically switched on and off. In each cycle, the first electromagnet is first activated to generate a repulsive force; then the first electromagnet is deactivated to eliminate the repulsive force between the first electromagnets. The calculation formula is as follows: Where n is the rotational speed, Given the periodic time, the formula for calculating the energy consumption of a single expansion or contraction cycle during expansion repulsion and contraction attraction is as follows: , This is the peak current. For coil resistance, For the power-on time, To release energy for rubber rebound; When the material viscosity exceeds the preset viscosity value, the second stage begins. The rotating center rod rotates, and when the increase in current fluctuation of the large drive motor reaches a specified value, the second electromagnet is activated. The trigger calculation formula is as follows: ,in The increase in current fluctuation for large drive motors; During the second stage, when sedimentation occurs at the bottom, the third stage is initiated, or the third stage is initiated periodically. This involves controlling the opening and closing of the bottom electromagnet assembly. A thickness sensor is installed at the bottom of the chamber to periodically detect whether sedimentation is occurring. The calculation formula is as follows: h is the sediment thickness, and r is the radius of the sphere; Step 3, spraying operation: When the viscosity stabilizes at the specified value, the hydraulic suction pump driven by the large drive motor sprays the mixed slurry out through the nozzle connected to the delivery pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are: In this invention, during the overall rotation of the rotating center rod, not only can a double vortex effect be formed through the first and second hemispheres, creating a double overpressure zone and a negative pressure zone, further increasing the suction and expansion effect on the material and further enhancing the dispersion and mixing of the material, but also, during rotation, the distance between the second and first hemispheres can be actively adjusted by the first electromagnet to expand the range of the overpressure zone and the negative pressure zone. At the same time, the pumping effect of the central jet can be formed through the gap between the first and second hemispheres to peel off the agglomeration of the material and further reduce the agglomeration phenomenon.

[0017] Furthermore, by activating the second electromagnet, the second hemisphere can be tilted. When the second hemisphere is tilted, the overall rotation can dig up the material that has formed clumps on the surface of the tilted part of the hopper. The increased contact area between the second hemisphere and the material when tilted increases the pushing force on the material. At the same time, in conjunction with the first electromagnet, the material can be quickly squeezed and crushed by the first hemisphere after being dug up, thereby reducing the phenomenon of material clumping at the bottom.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0021] like Figure 1 As shown, this application discloses a hydraulic spraying machine for slope landscaping protection, including a mixing chamber 100. A mounting frame 101 is fixedly connected to one side of the mixing chamber 100. A drive structure is installed inside the mounting frame 101. A rotating center rod 107 is rotatably connected inside the mixing chamber 100. Multiple sets of mixing rods 108 are fixedly connected to the outside of the rotating center rod 107 along its length. Each set includes multiple mixing rods 108 arranged in a cross shape on the outer wall of the rotating center rod 107. A first... A first hemisphere 109 is fixedly connected to a wear-resistant tensile rubber 111 on the side of the first hemisphere 109 away from the stirring rod 108. A second hemisphere 110 is fixedly connected to the side of the wear-resistant tensile rubber 111 away from the first hemisphere 109. A first electromagnet 112 is installed inside both the first hemisphere 109 and the second hemisphere 110. The two first electromagnets 112 are used to generate mutual attraction or repulsion after being energized, which drives the second hemisphere 110 to move away from and gradually approach the first hemisphere 109, forming a high-speed jet channel and increasing the shear force on the material.

[0022] Specifically, during use, the drive structure drives the rotating center rod 107 to rotate. When the rotating center rod 107 rotates, it drives the stirring rod 108 and the first hemisphere 109 to rotate. The first hemisphere 109 is connected to the second hemisphere 110 through wear-resistant tensile rubber 111. During rotation, the first hemisphere 109 and the second hemisphere 110 can generate overpressure and negative pressure zones, just like in existing technologies, producing suction or expansion effects on the mixture. Furthermore, during use, a flat jet channel is formed between the first hemisphere 109 and the second hemisphere 110. When the mixture passes through the flat jet channel, a double vortex phenomenon is generated, which can directly remove the agglomeration of materials.

[0023] Furthermore, during use, in order to ensure that the eddy current can reach the bottom of the mixing chamber 100, the operator can activate the two first electromagnets 112 to generate a repulsive magnetic force. Under the push of the repulsive magnetic force, the second hemisphere 110 can be gradually pushed away from the first hemisphere 109. As the second hemisphere 110 pushes the first hemisphere 109 away, the two wear-resistant stretching rubbers 111 will gradually extend. The gradually stretched wear-resistant stretching rubbers 111 will cooperate with the second hemisphere 110 to contact the chamber body of the mixing chamber 100. Thus, even when the material is relatively viscous, the generated eddy current can effectively entrain the material located inside the chamber, avoiding the phenomenon that the eddy current cannot carry the material deposited at the bottom for mixing when the material is relatively viscous.

[0024] Furthermore, during use, the energization of the two first electromagnets 112 can be canceled when the first hemisphere 109 and the second hemisphere 110 are rotated to a specified angle, thereby eliminating the repulsive force between the two first electromagnets 112. When the repulsive force disappears, the stretched wear-resistant rubber 111 will quickly rebound. When the wear-resistant rubber 111 rebounds quickly, it will drive the second hemisphere 110 to quickly approach the first hemisphere 109. When the second hemisphere 110 quickly approaches the first hemisphere 109, it will squeeze the material inside the first hemisphere 109 and the second hemisphere 110 again, forming a flipping jet pumping effect, pumping the fluid material to other positions, enhancing the stirring effect. Moreover, the repeated periodic energization of the two first electromagnets 112 can reduce the amount of material settling at the bottom of the mixing chamber 100.

[0025] like Figure 1 and Figure 7As shown, the drive structure includes a large drive motor 102, which is fixedly connected to a mounting frame 101. A hydraulic suction pump 103 and a small drive motor 104 are respectively mounted on the mounting frame 101. One end of the rotating center rod 107 passes through the outer wall of the mixing chamber 100 through a coupling. A connecting rod 105 is installed at the end of the output shaft of the small drive motor 104. A primary pulley is installed at the end of both the connecting rod 105 and the coupling. The primary pulley outside the connecting rod 105 and the coupling is connected by a primary belt drive. The inlet of the hydraulic suction pump 103 is the same as the outlet of the mixing chamber 100. A secondary pulley is installed outside the output shaft of the hydraulic suction pump 103 and the output shaft of the large drive motor 102. The two secondary pulleys are connected by a secondary belt drive. The outlet of the hydraulic suction pump 103 is connected to a conveying pipe 106. The end of the conveying pipe 106 away from the hydraulic suction pump 103 passes through the outer wall of the mounting frame 101.

[0026] Specifically, during operation, starting the large drive motor 102 rotates the two secondary pulleys, which in turn rotate the pumping worm gear inside the hydraulic suction pump 103. The rotating pumping worm gear in the hydraulic suction pump 103 draws material from the mixing chamber 100, and after material is drawn, it is transported to the conveying pipe 106. A spraying device, such as a spray pipe or spray gun, is connected to the conveying pipe 106 to spray the material onto the garden slope or lawn.

[0027] Furthermore, when the small drive motor 104 is started, it can drive the connecting rod 105 to rotate. The rotation of the connecting rod 105 will then drive the first-stage pulley on the coupling connected to the rotation center rod 107 to rotate, thereby driving the rotation center rod 107 to rotate. Alternatively, the large drive motor 102 and the small drive motor 104 can be connected via three-stage pulleys to achieve multi-stage linkage.

[0028] like Figure 7 As shown, the inner bottom wall of the mixing chamber 100 is integrally formed with a chamber body inclined part 500, and multiple sets of bottom electromagnets 600 are fixedly connected to the inner bottom wall of the mixing chamber 100.

[0029] Specifically, during use, the inclined section 500 of the silo body can continuously guide the slurry to the inlet of the hydraulic suction pump 103 as the material is continuously sucked out by the hydraulic suction pump 103.

[0030] Furthermore, by setting multiple sets of bottom electromagnet groups 600, the bottom electromagnet groups 600 can be activated during use to actively attract the second hemisphere 110. When actively attracting the second hemisphere 110, the second hemisphere 110 can be stably attracted to a position close to the inclined part 500 of the silo body. The rotation of the second hemisphere 110 actively sucks up the mud material deposited at the inclined part 500 of the silo body.

[0031] Furthermore, the distance between the two side walls of the mixing chamber 100 along its length is slightly less than the sum of the distances between the farthest ends of the two stirring rods in the same horizontal direction. This allows the side wall of the mixing chamber 100 to compress the second hemisphere 110 when the second hemisphere 110 rotates to the side wall, causing the second hemisphere 110 to actively compress the wear-resistant tensile rubber 111, creating a passive compression effect. Even with this passive compression effect, a pumping effect can still be achieved through the gap between the first hemisphere 109 and the second hemisphere 110. Additionally, the mutual compression between the first hemisphere 109 and the second hemisphere 110 can actively compress and crush agglomerated materials. Apart from the distance between the two side walls of the mixing chamber 100 along its length, the specific shape of the mixing chamber 100 is similar to that in the patent published in patent publication number CN115119572B.

[0032] The mounting bracket 101 is also equipped with a control console, which is used to control the on / off power and current direction of the first electromagnet 112 and the second electromagnet 200, as well as the start and stop of the large drive motor 102 and the small drive motor 104.

[0033] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: Compared with the prior art, in this embodiment, during the overall rotation of the rotating center rod 107, not only can a double vortex effect be formed by the first hemisphere 109 and the second hemisphere 110, forming a double overpressure zone and a negative pressure zone, further increasing the suction and expansion effect on the material, strengthening the dispersion and mixing of the material, but also, under rotation, the distance between the second hemisphere 110 and the first hemisphere 109 can be actively adjusted by the first electromagnet 112 to expand the range of the overpressure zone and the negative pressure zone. At the same time, the pumping effect of the central jet can be formed by the gap between the first hemisphere 109 and the second hemisphere 110 to peel off the agglomeration of the material and further reduce the agglomeration phenomenon of the material. Example 2

[0034] Considering that during use, thick mud materials may accumulate in large quantities on the inclined section 500 of the silo due to their poor fluidity and viscosity, simply rotating the first hemisphere 109 and the second hemisphere 110 may not generate an effective vortex dispersion phenomenon in the thick material. Without an effective vortex phenomenon, a large amount of thick material may still accumulate at the bottom of the inclined section 500 of the silo, leading to agglomeration. To address the above technical problems, based on Embodiment 1, this application proposes the following technical solution to solve the aforementioned technical problems: like Figure 4 As shown, two second electromagnets 200 are fixedly connected inside the first hemisphere 109 and the second hemisphere 110. The second electromagnets 200 inside the second hemisphere 110 and the first hemisphere 109 are flush. The two second electromagnets 200 inside the second hemisphere 110 and the first hemisphere 109 are located on both sides of the two first electromagnets 112.

[0035] Specifically, during use, when the slurry is still in a relatively viscous state, the second electromagnets 200 located on both sides can be activated. The multiple second electromagnets 200 are divided into two groups, one on the left and one on the right. During use, the second electromagnet 200 on the corresponding side can be activated according to the direction of rotation, so that the second electromagnets 200 on the corresponding side generate a repulsive force. When the second electromagnets 200 on the corresponding side generate a repulsive force, the second hemisphere 110 will tilt as a whole. When the second hemisphere 110 tilts and rotates to be close to the inclined part 500 of the silo, the second hemisphere 110 will form a bowl-shaped digging effect, thereby digging up the material that is stuck to the inclined part 500 of the silo. This enhances the turning rate of the material in a relatively viscous state and reduces the phenomenon of clumping at the bottom caused by the untimely turning of the relatively thick material.

[0036] Furthermore, after the second hemisphere 110 tilts to dig up the clumped material, the first electromagnet 112 can be quickly activated and the current direction controlled to cause adsorption between the second hemisphere 110 and the first hemisphere 109, thereby squeezing and dispersing the dug-up material and crushing the clumps.

[0037] like Figure 9 As shown, the side of the first hemisphere 109 closest to the second hemisphere 110 is a convex spherical surface, and the side of the second hemisphere 110 closest to the first hemisphere 109 is a concave spherical surface.

[0038] Specifically, the concave spherical side of the second hemisphere 110 can better dig up the clumped material, enhancing the digging effect. At the same time, during the material extrusion process, the convex spherical surface of the first hemisphere 109 can more closely cooperate with the concave spherical surface of the second hemisphere 110 to extrude the clumped material.

[0039] like Figure 6 As shown, a central fold 201 is provided on one side of the two adjacent wear-resistant tensile rubbers 111.

[0040] Specifically, when the first hemisphere 109 and the second hemisphere 110 are mutually attracted, there is wear-resistant tensile rubber 111 between the first hemisphere 109 and the second hemisphere 110. Therefore, during the mutual compression of the first hemisphere 109 and the second hemisphere 110, if one of the wear-resistant tensile rubber 111 does not deform outward but accumulates together without direction, the accumulated wear-resistant tensile rubber 111 will occupy the compression space between the first hemisphere 109 and the second hemisphere 110, thus affecting the effect of crushing and pulverizing the agglomerated material. However, by setting the central fold 201, the wear-resistant tensile rubber 111 can be bent through the central fold 201 as the center point after being compressed, so that the wear-resistant tensile rubber 111 folds regularly after being compressed, instead of folding into clumps randomly, reducing the phenomenon of clumps of wear-resistant tensile rubber 111 occupying the compression pores between the first hemisphere 109 and the second hemisphere 110.

[0041] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: Compared with Embodiment 1, in this embodiment, by activating the second electromagnet 200, the second hemisphere 110 can be tilted. When the second hemisphere 110 is tilted, the overall rotation can dig up the material that has formed clumps on the surface of the inclined part 500 of the bin. Furthermore, the contact area between the second hemisphere 110 and the material increases when tilted, increasing the pushing force on the material. At the same time, in conjunction with the first electromagnet 112, the first hemisphere 109 can quickly squeeze the dug-up material after it is dug up, thereby squeezing and crushing the dug-up material and reducing the phenomenon of material clumping at the bottom. Example 3

[0042] Considering that during use, although the central fold 201 can ensure that the wear-resistant tensile rubber 111 can be folded completely to reduce the space occupied by the twisting of the wear-resistant tensile rubber 111, material fatigue may occur at the central fold 201 position under long-term folding, which may cause the wear-resistant tensile rubber 111 to break completely at the central fold 201 position, this application proposes the following technical solution to solve the above technical problem, specifically: like Figure 6As shown, a folded chain mesh group 300 is integrally formed at the center of the wear-resistant tensile rubber 111.

[0043] Specifically, the folding chain mesh assembly 300 is composed of a metal chain mesh and an elastic rubber rope mesh. During repeated folding, the metal chain mesh and rubber rope mesh provide better resistance to folding compared to simple block rubber. In the folding chain mesh assembly 300, the metal provides strength support, while the rubber disperses stress and absorbs energy, preventing the problem that if a crack appears in the rubber block, the crack will gradually enlarge during repeated folding. Furthermore, the mesh design allows for more connections, ensuring that the breakage of a single chain will not affect other chains. Figure 8 As shown, multiple metal pull ropes 400 are integrally formed inside both wear-resistant tensile rubbers 111. These metal pull ropes 400 limit the maximum elongation of the wear-resistant tensile rubbers 111, preventing excessive elongation. Specifically, during use, the multiple metal pull ropes 400 limit the stretching state of the wear-resistant tensile rubbers 111. The metal pull ropes 400 can be connected to the folded chain mesh assembly 300, such as through hooking or clamping, increasing the connectivity between the wear-resistant tensile rubbers 111 and the folded chain mesh assembly 300. When the second electromagnets 200 generate repulsive forces and push each other, the wear-resistant tensile rubbers 111 will continuously stretch. This continuous stretching and digging... In the case of materials, the tensile force on the wear-resistant tensile rubber 111 will increase. As the tensile force increases, it may cause damage to the wear-resistant tensile rubber 111 if it becomes too large. Therefore, the metal pull rope 400 can limit the maximum extension of the wear-resistant tensile rubber 111. One end of the metal pull rope 400 is connected to the second hemisphere 110, and the other end is connected to the first hemisphere 109. When the wear-resistant tensile rubber 111 is stretched to its maximum, the metal pull rope 400 will intervene to bear the tensile force and prevent the wear-resistant tensile rubber 111 from being continuously compressed and extended.

[0044] Furthermore, during the energization of the first electromagnet 112 and the second electromagnet 200, both the rotating center rod 107 and the stirring rod 108 have conductive rods or conductive wires inside. A conductive slip ring is rotatably connected to the outside of the coupling connected to the rotating center rod 107. The conductive wires inside the rotating center rod 107 and the stirring rod 108 are energized through an external power source connected to the conductive slip ring.

[0045] The first electromagnet 112 and the second electromagnet 200 can be energized through designated lines. During application, they need to be connected to designated energized wires according to the actual situation.

[0046] like Figure 10 As shown, multiple second hemispheres 110 are fixedly connected by arc-shaped spiral stirring plates 700.

[0047] Specifically, multiple spiral stirring plates 700 can be connected between multiple second hemispheres 110. The two ends of each spiral stirring plate are respectively set on two second hemispheres 110 in opposite directions on both sides of the rotating center rod. The spiral stirring plates 700 continuously assist the second hemispheres 110 in stirring the material in a spiral shape, thereby further enhancing the stirring intensity.

[0048] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: Compared with Embodiment 2, in this embodiment, the folding chain mesh group 300 is used to support the folding point of the wear-resistant tensile rubber 111. During the continuous folding and stretching of the wear-resistant tensile rubber 111, it bears the central stress point, avoiding the situation where the wear-resistant tensile rubber 111 breaks from the center during the continuous folding process. In addition, the metal pull rope 400 is used to reduce the situation where the wear-resistant tensile rubber 111 is overstretched and folds over, ensuring that the second hemisphere 110 can operate stably during use.

[0049] This invention also provides a method for hydroseeding and planting grass using a hydraulic hydroseeding machine for slope landscaping protection, such as... Figure 11 As shown, it includes the following steps: Step 1: Add grass seeds, water-retaining agent, adhesive, and fertilizer to the mixing chamber 100 in proportion, and add water to 80% of the volume to form a mixture. Step 2: Mix the materials in stages. A viscosity detector is installed inside the mixing chamber 100, and the mixture is stirred in stages according to the detected viscosity: When the material viscosity is less than or equal to a preset viscosity value (e.g., 50 Pa·s), the first stage begins. The small drive motor 104 is activated to rotate the central rotating rod 107. When the rotation speed of the central rotating rod 107 reaches 20 RPM, the first electromagnet 112 is periodically switched on and off. In each cycle, the first electromagnet 112 is activated first, generating a repulsive force that causes the wear-resistant tensile rubber 111 between the first hemisphere 109 and the second hemisphere 110 to gradually extend. This allows the second hemisphere 110 to contact the mixing chamber, entraining the material inside. Then, the first electromagnet 112 is deactivated, eliminating the repulsive force between the two electromagnets. The wear-resistant tensile rubber 111 quickly rebounds, and the second hemisphere 110 rapidly approaches the first hemisphere 109, compressing the material between them. The calculation formula is: Where 60 represents 60 seconds, or 1 minute. The periodic time represents the time it takes for the object to rotate one revolution; specifically, the energization time of the first electromagnet 112 is 0.3 seconds. The de-energization time of the first electromagnet 112 is 0.7 seconds. .

[0050] The formula for calculating the energy consumption of a single expansion and contraction during the expansion repulsion and contraction attraction in the first hemisphere 109 and the second hemisphere 110 is as follows: , This is the peak current. For coil resistance, For the power-on time, To release energy for rubber rebound; This indicates the extent to which the rubber is stretched, or in other words, the pre-measured tensile value of the rubber. For example, the rubber material is made into a standard specimen and subjected to a tensile-rebound cycle test on a universal tensile testing machine to obtain the energy value generated when the rubber rebounds. After obtaining a quantifiable energy value, it is possible to pre-measure and use techniques based on the degree of expansion and separation of the first hemisphere 109 and the second hemisphere 110, thereby obtaining a calibration reference value during actual use. The calculated value is then dynamically obtained based on the calibration reference value. This value can also be obtained based on the actual rubber material data during rubber installation.

[0051] When the material viscosity exceeds a preset viscosity value (e.g., 50 Pa·s), the second stage begins. The small drive motor 104 is activated to rotate the central rotating rod 107. When the current fluctuation of the large drive motor 102 reaches a specified value, the second electromagnet 200 is triggered, causing the second hemisphere to tilt to one side. During rotation, the material that has clumped onto the inclined portion 500 of the silo is lifted. The trigger calculation formula is: ,in The current fluctuation of the large drive motor 102 represents its stirring power. The second electromagnet 200 is activated when the specified value is reached; the specified value can be set to 15%-25%, preferably 20%. Specifically, an analyzer or detector can be connected to the large drive motor 102 to detect the current fluctuation of the large drive motor 102.

[0052] In the second stage, the digging steps of the second electromagnet 200 include: according to the rotation direction of the rotating center rod 107, activating the second electromagnet 200 on the side closer to the rotation direction, so that the second hemisphere 110 tilts as a whole; turning off the second electromagnet 200 and activating the first electromagnet 112 to attract each other. Specifically, the start and stop of the second electromagnet 200 are determined based on whether clumps appear inside the mixing chamber. When the operator stands above the mixing chamber 100 and sees clumps inside, the electromagnet is started; when the clumps at one end of the mixing chamber decrease, the electromagnet is stopped. Alternatively, the start and stop operations can be performed based on the thickness value detected by the viscosity sensor.

[0053] During the second stage, when sedimentation occurs at the bottom, the third stage is initiated, or the third stage is initiated periodically. This involves controlling the opening and closing of the bottom electromagnet assembly 600. A thickness sensor is installed at the bottom of the chamber to periodically detect whether sedimentation occurs. The calculation formula is as follows: ; When the bottom electromagnet assembly 600 is energized, it generates an attractive force to assist the second hemisphere 110 in scraping the bottom of the compartment. Step 3, spraying operation: When the viscosity stabilizes at the preset value, the hydraulic suction pump 103 driven by the large drive motor 102 sprays the mixed slurry out through the nozzle connected to the delivery pipe 106.

[0054] Finally, the electromagnets are de-energized in stages to end the spraying operation. Specifically, during the shutdown of multiple electromagnets, the operators shut down the corresponding electromagnets one by one according to a preset sequence or based on usage. This is because if all electromagnets are shut down simultaneously during use, components that are extending or under stress may collide or violently rebound due to the sudden loss of magnetic restraint. If the bottom electromagnet loses its attraction first, the scraped sediment may fall back to the bottom of the tank.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
