Description

Technical Field

[0001] The present invention relates to the technical field of concrete mixing, and particularly to an energy-saving vehicle-mounted concrete mixing system and method. Background Art

[0002] Flat-mouth concrete mixer trucks are mainly used in projects such as rural road construction and concrete ditch pouring for farmland water conservancy. Its mechanism includes a mixing system and an automatic feeding mechanism. The mixing system mostly uses a flat-mouth disk forced mixer. The mixing barrel is fixed on the vehicle body, and there is a discharge port at the bottom of the barrel. A vertical mixing shaft in the barrel is driven by devices such as a hydraulic motor to forcibly stir the cement and sand in the mixing barrel, fusing them together to achieve the function of mixing concrete while moving.

[0003] Chinese Patent CN 112809928 A discloses a walking flat-mouth concrete mixer truck, including a vehicle body. At the top of the tail of the vehicle body, a plurality of support columns are fixedly connected. The top of the support column is fixedly connected with a mixing barrel. A power mechanism is fixedly installed in the vehicle body. The power mechanism includes an engine, a four-wheel drive split gearbox, a first reduction box, and a steering gearbox, which transmits the power generated by the engine to the vehicle body drive mechanism and the rotating shaft in the mixing barrel, optimizing the design of the concrete mixer truck and realizing that one engine provides power to the entire device, reducing production costs.

[0004] However, there are still some problems with this technical solution. The common models of flat-mouth concrete mixer trucks have mixing volumes of 3 cubic meters, 4 cubic meters, and 5 cubic meters. Some small mixer trucks have a mixing volume of only 2 cubic meters, which are small and lightweight, suitable for private use, and can be used in complex environments such as rural areas, fields, and mountain villages. Therefore, they often encounter uphill and downhill situations. However, the mixing barrel in the mixing system has a small volume and is often full of concrete. When walking on a road with a relatively high slope, it is easy to have the problem of concrete spilling out;

[0005] Simply raising the barrel body can solve the problem of concrete leakage, but it also changes the small size characteristic of the mixer truck. Moreover, the feeding mechanism for feeding materials into the mixing barrel also needs to be lengthened accordingly. The enlargement of the overall volume of the vehicle will limit its use. Therefore, this method is not suitable;

[0006] Without changing the height of the mixing barrel, adding movable baffles to the barrel body can also prevent concrete leakage. However, due to the self-characteristics of concrete, it is easy to flow into the gap between the baffle and the barrel body and solidify, which is not only difficult to clean but also affects the movement of the baffle. Therefore, how to handle the concrete leakage is an urgent problem to be solved in the concrete mixing system of flat-mouth mixer trucks, and the above technical solutions have not effectively solved this technical problem. Summary of the Invention

[0007] The object of the present invention is to provide an energy-saving vehicle-mounted concrete mixing system and method in view of the deficiencies of the prior art. By providing a spill-proof member that can be lifted and horizontally moved to block the materials in the mixing drum, while preventing spills, it is convenient to clean the spill-proof member. In cooperation with the cleaning mechanism, the materials attached to the spill-proof member are shaken off into the mixing drum, improving the cleanliness of the spill-proof member during the working process, and solving the problems that the materials in the flat-mouth concrete mixer truck are prone to spill due to tilting and are inconvenient to clean.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] An energy-saving vehicle-mounted concrete mixing system, comprising:

[0010] A mixing drum provided on the vehicle body;

[0011] A detection unit for detecting the tilting state of the mixing drum;

[0012] A spill-proof member movably provided outside the mixing drum, which is lifted upward and attached to the outside of the mixing drum after the vehicle body tilts;

[0013] A guiding mechanism for guiding the spill-proof member;

[0014] A cleaning mechanism provided outside the mixing drum for vibrating the spill-proof member; and

[0015] A control mechanism for driving the spill-proof member and the cleaning mechanism to work.

[0016] Specifically, the spill-proof member is preferably but not limited to being set such that its top is lower than the top of the mixing drum. In the initial state, the spill-proof member is located below the outside of the mixing drum to avoid hindering the operation of feeding concrete materials into the mixing drum. After the mixing drum is filled with materials, during the process of the vehicle body moving, concrete mixing is carried out simultaneously. During this period, the detection unit monitors the tilt of the mixing drum. When it is detected that the vehicle body passes through a steeply inclined road surface, the control mechanism is activated and the spill-proof member is lifted upward and closely attached to the outside of the mixing drum to block the materials in the mixing drum and prevent the materials from spilling out;

[0017] The cleaning mechanism knocks on the spill-proof member to shake off the concrete attached to the spill-proof member into the mixing drum, which not only improves the recovery rate of the materials, but also avoids the problem that the spill-proof member cannot work properly due to the solidification of the materials adhered to it, making the use more reliable; this solution realizes the function of preventing the concrete materials from spilling out due to the tilting of the mixer truck without increasing the height of the mixing drum and ensuring the compactness of the mixer truck.

[0018] As a preference, the anti-spill member includes two arc-shaped plates concentric with the mixing drum. The two arc-shaped plates are respectively arranged on both sides of the mixing drum along the traveling direction of the vehicle body, and there is a gap between the anti-spill member and the mixing drum.

[0019] Specifically, the anti-spill member can move horizontally and longitudinally on the outer side of the mixing drum. In the initial state, the anti-spill member is located at the bottom end of its moving range. By leaving a gap between the anti-spill member and the mixing drum, an operating space is reserved for the cleaning and maintenance of the anti-spill member and the mixing drum. Moreover, the inner wall of the anti-spill member and the outer wall of the mixing drum can be cleaned without disassembling the anti-spill member, which is convenient to use.

[0020] Furthermore, the distance between the anti-spill member and the mixing drum does not need to be too large to meet the above-mentioned function of facilitating maintenance and cleaning. Therefore, the space occupied by the anti-spill member horizontally is also small, which will not change the compact characteristics of the mixer truck and can meet the normal use of the mixer truck.

[0021] As another preference, the guiding mechanism includes:

[0022] A guiding frame located on the outer side of the mixing drum;

[0023] A guiding groove provided on the guiding frame. The guiding groove is quadrilateral in shape. The top side and the bottom side of the quadrilateral are both inclined. The other two vertical sides of the quadrilateral are parallel to the side wall of the mixing drum, and the distance between the two vertical sides is the same as the distance between the anti-spill member and the mixing drum; and

[0024] A guide rod provided on the outer side of the anti-spill member and inserted into the guiding groove.

[0025] Specifically, the movement track of the anti-spill member along the guiding groove is quadrilateral. When the anti-spill member moves upward along the outer vertical side, it does not contact the mixing drum to reduce the upward movement resistance; after the anti-spill member moves to the top, it moves horizontally along the top hypotenuse and adheres tightly to the outer side of the mixing drum to improve the sealing performance between the two and prevent the material from spilling out;

[0026] When the anti-spill member moves downward along the inner vertical side, the anti-spill member is in close contact with the mixing drum. While preventing the material from spilling out, the top edge of the mixing drum can scrape the anti-spill member to scrape off the material adhering to the inner wall of the anti-spill member and further improve the cleanliness of the anti-spill member.

[0027] As a preference, the guiding mechanism further includes:

[0028] A check step provided at the corner of the guiding groove to prevent the guide rod from moving back;

[0029] A support plate provided on the outer side of the anti-spill member, and the guide rod is movably inserted on the support plate; and

[0030] A reset piece is provided on the guide rod.

[0031] Specifically, the reset member is preferably a support spring. Under the action of the support spring, the guide rod moves outward and is inserted into the guide groove. The check step prevents the guide rod from moving back, thereby ensuring that the anti-spill member stably moves in one direction along the guide groove.

[0032] As another preferred embodiment, the cleaning mechanism includes:

[0033] a cleaning bracket provided on the outside of the mixing drum;

[0034] a plurality of rapping members movably arranged on the cleaning bracket and configured to rap the anti-spill member after rotating; and

[0035] A force storage member that pushes the rapping member against the anti-spill member;

[0036] The top of the rapping member is not lower than the top of the mixing drum.

[0037] Specifically, the vibrating member is rotatably installed on the cleaning bracket, and the vibrating members are evenly distributed in a ring on the outside of the mixing drum. Under the push of the force storage member, the top of each vibrating member is against the anti-spill member. The top of the vibrating member is preferably flush with the top of the mixing drum, and the material scraped off by the top edge of the mixing drum can be vibrated to make it fall into the mixing drum.

[0038] As a preference, the control mechanism includes:

[0039] A push plate movably inserted laterally between the bottoms of the two anti-spill parts; and

[0040] A driving unit drives the push plate to move up and down.

[0041] Specifically, the detection unit is used to control the start-up of the driving unit; the driving unit drives the push plate to move up and down, and the push plate drives the two anti-spill parts to move up and down synchronously.

[0042] As another preferred embodiment, the control mechanism further includes:

[0043] A ring plate is rotated on the outside of the mixing drum and drives the rapping member to swing after rotation, and the bottom of the ring plate is evenly distributed with inclined panels for moving the rapping member; and

[0044] A ratchet member is engaged with the ring plate to perform one-way transmission.

[0045] Specifically, the ratchet part is located on the outside of the ring plate, and the ratchet part drives the ring plate to rotate. After the ring plate rotates, the inclined plate intermittently moves each vibration part to deflect and compress the force storage part to store energy; when the inclined plate is separated from the vibration part, the vibration part rotates rapidly under the action of the force storage part and hits the anti-spill part, which can make the material fall back into the mixing drum.

[0046] As a preference, the control mechanism further includes:

[0047] a screw member provided on the push plate; and

[0048] A driven ring fixedly arranged at the bottom of the ratchet member and sleeved on the outside of the screw member;

[0049] The screw member drives the driven ring to rotate during the lifting process;

[0050] A cavity is provided inside the ratchet component, and the inner diameter of the cavity is greater than the outer diameter of the screw component.

[0051] Specifically, the driven ring is concentric with the ratchet member, and the inner ring of the driven ring is arranged in the thread groove of the screw member. The screw member drives the driven ring and the ratchet member to rotate as the push plate moves up and down.

[0052] As another preferred embodiment, the control mechanism further includes:

[0053] A support provided at the top of the outer side of the mixing drum and located between the two anti-spill parts;

[0054] A positioning plate provided on the support and extending transversely through the two anti-spill parts; and

[0055] A vertical groove provided on the anti-spill member and matching with the positioning plate;

[0056] The ring plate and the ratchet wheel are both rotatably arranged in the support, and the screw rod passes through the support.

[0057] Specifically, by providing a positioning plate and a push plate, the top and bottom ends of the spill prevention member are guided at the same time, so as to improve the stability of the spill prevention member when it moves up and down.

[0058] Another object of the present invention is to address the shortcomings of the existing technology and provide an energy-saving vehicle-mounted concrete mixing method. By arranging a detection unit on the vehicle body to monitor the inclination of the mixing drum, and automatically extending the height of the mixing drum when it tilts, the material is prevented from spilling. This achieves the effect of improving the anti-spill performance without changing the compactness of the mixer truck.

[0059] To achieve the above object, the present invention provides the following technical solutions:

[0060] An energy-saving vehicle-mounted concrete mixing method comprises the following steps:

[0061] Step 1: Place the anti-spill component below the outside of the mixing drum.

[0062] Step 2: Add concrete materials into the mixing drum.

[0063] Step 3: During the movement of the vehicle body, the mixing drum simultaneously conducts the concrete mixing work, and the inclination state of the mixing drum is monitored by the detection unit.

[0064] Step 4: When the detection unit monitors that the mixing drum is inclined, the push plate in the control mechanism is used to lift the anti-spill component upward, and in cooperation with the guiding mechanism, the anti-spill component is attached to the outside of the mixing drum to prevent the materials in the mixing drum from spilling out.

[0065] Step 5: When the mixing drum returns to the horizontal state, the anti-spill component moves downward along the outer side wall of the mixing drum, and the materials attached to the anti-spill component are scraped off.

[0066] Step 6: Start the vibrating component in the cleaning mechanism to vibrate the downward-moving anti-spill component, vibrate the materials down and make them fall back into the mixing drum for material recovery.

[0067] Step 7: After the concrete mixing is completed, restore the anti-spill component to its initial position.

[0068] The beneficial effects of the present invention are as follows:

[0069] (1) The present invention lengthens the height of the mixing drum by setting a horizontally movable and vertically liftable anti-spill component outside the mixing drum, which functions to prevent the materials inside the mixing drum from spilling when the mixing drum is inclined. By leaving a gap between the anti-spill component and the mixing drum, an operation space is provided for the cleaning and maintenance of the anti-spill component and the mixing drum. The inner wall of the anti-spill component and the outer wall of the mixing drum can be cleaned without disassembling the anti-spill component, which is convenient to use. Since the anti-spill component occupies a relatively small space horizontally, the anti-spill effect is improved on the premise of meeting the requirement of the compactness of the mixer truck.

[0070] (2) The present invention drives the anti-spill component to perform a quadrilateral movement through the guiding mechanism. During the upward movement of the anti-spill component, it does not contact the mixing drum to reduce the upward movement resistance; when the anti-spill component moves to the top and is tightly attached to the outside of the mixing drum to prevent the materials from spilling out; during the downward movement of the anti-spill component, it is in close contact with the mixing drum to scrape off the materials attached to the anti-spill component, improving the cleanliness of the anti-spill component and solving the problem that it is difficult to clean the materials attached to the anti-spill component after solidification.

[0071] (3) The present invention sets a cleaning mechanism, and the vibrating component is used to vibrate the downward-moving anti-spill component to make the materials fall off, which not only improves the cleanliness of the anti-spill component but also recovers the materials.

[0072] (4) By setting up a control mechanism, while the push plate drives the anti-spill component to move, the vibration component is driven to vibrate through the screw component and the ring plate, realizing the function of simultaneously controlling the work of the anti-spill component and the vibration component. The structure is simple, easy to use, without the need to additionally set up multiple sets of electric drive devices, more energy-saving, and with low use cost.

[0073] In summary, the present invention has the advantages of improving the anti-spill effect of the mixing drum without changing the small size of the mixer truck, having a simple structure, occupying a small space, and being easy to use. Description of the Drawings

[0084] As Figure 1-2 shown, this embodiment provides an energy-saving vehicle-mounted concrete mixing system, including:

[0085] A mixing drum 1 provided on the vehicle body 100;

[0086] A detection unit 2 for detecting the inclination state of the mixing drum 1;

[0087] A spill prevention member 3 movably provided outside the mixing drum 1 and rising upward and adhering to the outside of the mixing drum 1 after the vehicle body 100 inclines;

[0088] A guiding mechanism 4 for guiding the spill prevention member 3;

[0089] A cleaning mechanism 5 provided outside the mixing drum 1 for vibrating the spill prevention member 3; and

[0090] A control mechanism 6 for driving the spill prevention member 3 and the cleaning mechanism 5 to work.

[0091] Specifically, the detection unit 2 may adopt an inclination sensor, and the detection unit 2 is provided on the vehicle body 100 or the mixing drum 1.

[0092] During the working process, the spill prevention member 3 is preferably but not limited to being set such that its top is lower than the top of the mixing drum 1. In the initial state, the spill prevention member 3 is located below the outside of the mixing drum 1 so as not to hinder the operation of feeding concrete materials into the mixing drum 1. After the feeding in the mixing drum 1 is completed, during the process of the vehicle body 100 traveling, concrete mixing is carried out simultaneously. During this period, the inclination of the mixing drum 1 is monitored by the detection unit 2. When it is detected that the vehicle body 100 passes through a steeply inclined road surface, the control mechanism 6 is activated and the spill prevention member 3 is lifted upward and adhered tightly to the outside of the mixing drum 1 to block the materials in the mixing drum 1 and prevent the materials from spilling out;

[0093] The anti-spill member 3 is knocked by the cleaning mechanism 5, and the concrete adhering to the anti-spill member 3 is shaken off into the mixing drum 1, which not only improves the recovery rate of the material, but also avoids the problem that the anti-spill member 3 cannot lift and lower normally after the material adheres to the anti-spill member 3 and solidifies, making the use more reliable; this solution realizes the function of preventing the concrete material from spilling out due to the inclination of the mixer truck without increasing the height of the mixing drum 1 and ensuring the compactness of the mixer truck.

[0094] As Figure 1 shown, further, the anti-spill member 3 includes two arc-shaped plates concentric with the mixing drum 1. The two arc-shaped plates are respectively arranged on both sides of the mixing drum 1 along the traveling direction of the vehicle body 100, and there is a gap between the anti-spill member 3 and the mixing drum 1.

[0095] Specifically, the angle of the arc-shaped plate is not greater than 180 degrees. The anti-spill member 3 can move horizontally and vertically on the outside of the mixing drum 1. In the initial state, the anti-spill member 3 is located at the bottom of its moving range. By leaving a gap between the anti-spill member 3 and the mixing drum 1, an operation space is reserved for the cleaning and maintenance of the anti-spill member 3 and the mixing drum 1. Moreover, the inner wall of the anti-spill member 3 and the outer wall of the mixing drum 1 can be cleaned without disassembling the anti-spill member 3, which is convenient to use;

[0096] And, the distance between the anti-spill member 3 and the mixing drum 1 does not need to be too large to meet the above-mentioned function of facilitating maintenance and cleaning. Therefore, the space occupied by the anti-spill member 3 horizontally is also small, and it will not change the compact characteristics of the mixer truck and can meet the normal use of the mixer truck.

[0097] As Figure 1 and Figure 5 shown, furthermore, the guiding mechanism 4 includes:

[0098] A guiding frame 41 located outside the mixing drum 1;

[0099] A guiding groove 42 provided on the guiding frame 41. The guiding groove 42 is quadrilateral. The top side and the bottom side of the quadrilateral are both inclined. The other two vertical sides of the quadrilateral are both parallel to the side wall of the mixing drum 1. The distance between the two vertical sides is the same as the distance between the anti-spill member 3 and the mixing drum 1; and

[0100] A guide rod 43 provided on the outside of the anti-spill member 3 and inserted into the guiding groove 42.

[0101] Specifically, the installation of the guiding frame 41 is selected according to specific circumstances. It can be fixed on the outside of the mixing drum 1 or on the vehicle body 100. The movement track of the anti-spill member 3 along the guiding groove 42 is quadrilateral, specifically as follows:

[0102] When the anti-spill component 3 rises, it moves upward along the outer vertical side. During this process, the anti-spill component 3 does not contact the mixing drum 1 to reduce the upward movement resistance. After the anti-spill component 3 moves to the top, it moves horizontally along the top bevel and presses tightly against the outside of the mixing drum 1 to improve the sealing between the two and prevent the material from spilling out.

[0103] When the anti-spill component 3 moves downward, it moves downward along the inner vertical side. During this process, the anti-spill component 3 fits tightly against the mixing drum 1. While preventing the material from spilling out, the top edge of the mixing drum 1 can scrape the anti-spill component 3 to scrape off the material adhering to the inner wall of the anti-spill component 3 and further improve the cleanliness of the anti-spill component 3.

[0104] As Figure 5 shown, further, the guiding mechanism 4 further includes:

[0105] A check step 44 provided at the corner of the guiding groove 42 to prevent the guide rod 43 from moving back;

[0106] A support plate 45 provided on the outside of the anti-spill component 3, and the guide rod 43 is movably inserted into the support plate 45; and

[0107] A reset member 46 provided on the guide rod 43.

[0108] Specifically, the reset member 46 is preferably a support spring. The guide rod 43 moves outward under the action of the support spring and is inserted into the guiding groove 42. By providing the check step 44, the guide rod 43 is prevented from moving back, thereby ensuring that the anti-spill component 3 moves stably along the guiding groove 42 in one direction.

[0109] As Figure 4 shown, furthermore, the cleaning mechanism 5 includes:

[0110] A cleaning bracket 51 provided on the outside of the mixing drum 1;

[0111] A plurality of vibrating members 52 movably provided on the cleaning bracket 51 and knocking on the anti-spill component 3 after rotation; and

[0112] A power storage member 53 that pushes the vibrating member 52 against the anti-spill component 3;

[0113] The top end of the vibrating member 52 is not lower than the top end of the mixing drum 1.

[0114] Specifically, the power storage member 53 is preferably but not limited to a spring member. The vibrating member 52 is rotatably installed on the cleaning bracket 51. The vibrating members 52 are evenly distributed annularly on the outside of the mixing drum 1. Under the push of the power storage member 53, the top ends of the vibrating members 52 all press against the anti-spill component 3. The top end of the vibrating member 52 is preferably flush with the top end of the mixing drum 1, and can vibrate the material scraped off by the top edge of the mixing drum 1 to make it fall into the mixing drum 1.

[0115] like Figure 1 and Figure 3 As shown, further, the control mechanism 6 includes:

[0116] A push plate 61 that is laterally movably inserted between the bottoms of the two anti-spill parts 3; and

[0117] A driving unit 62 drives the push plate 61 to move up and down.

[0118] Specifically, the driving unit 62 can be an electric push rod or a hydraulic push rod, and the detection unit 2 is used to control the start of the driving unit 62; the driving unit 62 drives the push plate 61 to move up and down, and the push plate 61 drives the two anti-spill parts 3 to move up and down synchronously.

[0119] like Figure 4 As shown, further, the control mechanism 6 also includes:

[0120] A ring plate 63 is rotated on the outside of the mixing drum 1 and drives the rapping member 52 to swing after the rotation, and the bottom of the ring plate 63 is evenly distributed with inclined panels for moving the rapping member 52; and

[0121] A ratchet wheel 64 is engaged with the ring plate 63 to perform one-way transmission.

[0122] Specifically, the ratchet member 64 is located on the outside of the ring plate 63, and the ratchet member 64 drives the ring plate 63 to rotate unidirectionally. After the ring plate 63 rotates, the inclined plate intermittently shifts each rapping member 52 to deflect and compress the force storage member 53 to store energy; when the inclined plate is separated from the rapping member 52, the rapping member 52 rotates rapidly under the action of the force storage member 53 and hits the anti-spill member 3, and at the same time, the material attached to the anti-spill member 3 and the material scraped off by the mixing drum 1 are vibrated and fall off. The direction of the rapping force is toward the inside of the mixing drum 1, and the material has a tendency to move inward laterally. Therefore, the material can be better returned to the mixing drum 1; by arranging a plurality of evenly distributed inclined plates at the bottom of the ring plate 63, the number of times each rapping member 52 is shifted during the rotation of the ring plate 63 can be increased, thereby increasing the rapping frequency.

[0123] like Figure 6 As shown, further, the control mechanism 6 also includes:

[0124] a screw member 65 provided on the push plate 61; and

[0125] A driven ring 66 fixedly mounted on the bottom of the ratchet member 64 and sleeved on the outside of the screw member 65;

[0126] The screw member 65 drives the driven ring 66 to rotate during the lifting process;

[0127] The interior of the ratchet member 64 is provided with a cavity, and the inner diameter of the cavity is larger than the outer diameter of the screw member 65.

[0128] Specifically, the driven ring 66 is concentric with the ratchet member 64. The inner ring of the driven ring 66 is arranged in the thread groove of the screw member 65. When the screw member 65 moves up and down with the push plate 61, the driven ring 66 and the ratchet member 64 are driven to rotate.

[0129] During the process that the push plate 61 drives the anti-spill member 3 to move up and closely adhere to the outer side of the mixing drum 1, the ratchet member 64 does not drive the ring plate 63 to rotate, so as to avoid the problem that the anti-spill member 3 shakes after being knocked, resulting in a decrease in the sealing performance between the anti-spill member 3 and the mixing drum 1 and affecting the anti-spill effect.

[0130] During the process that the push plate 61 drives the anti-spill member 3 to move down, the ratchet member 64 drives the ring plate 63 to rotate, thereby driving each vibration member 52 to perform vibration cleaning on the anti-spill member 3.

[0131] Of course, on the premise of satisfying that the anti-spill member 3 can be closely attached to the mixing drum 1 during the anti-spill process, the ratchet member 64 can also be replaced with other structures capable of transmitting power to the ring plate 63. Embodiment Two

[0132] As Figure 3 shown, the same or corresponding components as those in Embodiment One adopt the corresponding reference numerals in Embodiment One. For the sake of simplicity, only the differences from Embodiment One will be described below. The difference between this Embodiment Two and Embodiment One lies in:

[0133] In this embodiment, the control mechanism 6 further includes:

[0134] A support 67 arranged at the top outside the mixing drum 1 and located between the two anti-spill members 3;

[0135] A positioning plate 68 arranged on the support 67 and horizontally penetrating through the two anti-spill members 3; and

[0136] A vertical groove 69 arranged on the anti-spill member 3 and matching with the positioning plate 68;

[0137] Both the ring plate 63 and the ratchet member 64 are rotatably arranged in the support 67, and the screw member 65 penetrates through the support 67.

[0138] Specifically, the support 67 can be arranged on the outer side wall of the mixing drum 1 according to specific circumstances, or can be arranged on the vehicle body 100. For example, when the angle of the arc-shaped plate is 180 degrees, the two arc-shaped plates form a circular ring after closely adhering to the mixing drum 1. At this time, the support 67 needs to be arranged on the vehicle body 100.

[0139] By setting the positioning plate 68 and the pushing plate 61, the top and bottom of the anti-spill member 3 are guided simultaneously to improve the stability of the anti-spill member 3 during its up and down movement.

[0140] It should be noted that the control mechanism 6 is preferably but not limited to the methods described in Embodiment 1 and Embodiment 2. Any device that can drive the anti-spill member 3 to move up and down and stick to and move away from the mixing drum 1 can be used to manufacture the control mechanism 6. Embodiment 3

[0141] As Figure 7 shown, this embodiment provides an energy-saving vehicle-mounted concrete mixing method, including the following steps:

[0142] Step 1: Place the anti-spill member 3 below the outside of the mixing drum 1.

[0143] Step 2: Add concrete materials into the mixing drum 1.

[0144] Step 3: During the movement of the vehicle body 100, the mixing drum 1 simultaneously performs the concrete mixing work, and the detection unit 2 monitors the inclination state of the mixing drum 1.

[0145] Step 4: When the detection unit 2 monitors that the mixing drum 1 is inclined, the pushing plate 61 in the control mechanism 6 lifts the anti-spill member 3 upward, and in cooperation with the guiding mechanism 4, the anti-spill member 3 is attached to the outside of the mixing drum 1 to prevent the materials in the mixing drum 1 from spilling out.

[0146] Step 5: When the mixing drum 1 returns to the horizontal state, the anti-spill member 3 moves down along the outer wall of the mixing drum 1, and the materials attached to the anti-spill member 3 are scraped off.

[0147] Step 6: Start the vibrating member 52 in the cleaning mechanism 5 to vibrate the downward-moving anti-spill member 3, vibrate the materials down and make them fall back into the mixing drum 1 for material recovery.

[0148] Step 7: After the concrete mixing is completed, return the anti-spill member 3 to its initial position.

[0149] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
