[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1 To Attachment Figure 6 The present invention is further described in detail.

[0029] The embodiment of the present invention relates to a concrete feeding, mixing and discharging integrated machine, including a feeding shell bucket 21, a mechanical arm 20 and a mixing bucket 10, a mixing motor 16 is installed at one end of the mixing bucket 10, the mixing bucket 10 and the mixing motor 16 are connected by screws, a first rotary support 12 is installed at the other end of the mixing bucket 10, the mixing bucket 10 and the first rotary support 12 are connected by screws, the bottom of the mixing bucket 10 is hinged to a loader connecting arm 18, and the middle of the side of the mixing bucket 10 is hinged to a loader connecting middle arm; the other end of the first rotary support 12 is installed with a bracket 1 A second slewing support 13 is installed above the bracket 1, and a main arm 14 is provided on the second slewing support 13; the main arm 14 is hinged to the mechanical arm 20, and a lifting cylinder 19 is installed between the main arm 14 and the mechanical arm 20 in a hinged manner; a telescopic cylinder 15 is installed between the first section and the second section of the mechanical arm 20, and a telescopic cylinder 15 is installed between the second section and the third section of the mechanical arm 20. A feeding shell bucket 21 is provided on the top of the third section of the mechanical arm 20. The feeding shell bucket 21 is opened and closed by the shell bucket cylinder, so that the feeding shell bucket 21 can grasp and discharge materials.

[0030] Specifically, the inner ring of the first rotary support 12 is connected to the mixing bucket 10, and the mixing bucket 10 is connected to the inner ring of the first rotary support 12 by screws, the outer ring of the first rotary support 12 is connected to the bracket 1, and the outer ring of the first rotary support 12 is connected to the bracket 1 by screws; the outer ring of the second rotary support 13 is connected to the bracket 1, and the bracket 1 is connected to the outer ring of the second rotary support 13 by screws, the inner ring of the second rotary support 13 is connected to the main arm 14, and the inner ring of the second rotary support 13 is connected to the main arm 14 by screws; motors are respectively installed on the main arm 14 and the mixing bucket 10 to drive the first rotary support 12 and the second rotary support 13, and by controlling the rotation of the two motors, a 720° rotation of the main arm 14 can be achieved.

[0031] The main arm 14 is hinged to the mechanical arm 20, and a lifting cylinder 19 is installed between the main arm 14 and the mechanical arm 20 in a hinged manner; a telescopic cylinder 15 is installed between the first section and the second section of the mechanical arm 20 in a hinged manner, and a telescopic cylinder 15 is installed between the second section and the third section of the mechanical arm 20 in a hinged manner. By controlling the contraction action of the lifting cylinder 19 and the telescopic cylinder 15, the mechanical arm 20 can be swung up and down at an angle and automatic telescoping between two adjacent sections of the mechanical arm 20 can be achieved.

[0032] The mixing bucket 10 is equipped with an engine, a motor, a hydraulic pump, a multi-way valve and a wireless control device, and the main arm 14 is equipped with a motor. The output of the engine is connected to the hydraulic pump, the hydraulic pump is connected to the multi-way valve, the multi-way valve and the motor are connected to the wireless control device to realize wireless remote control of the oil supply of the multi-way valve and the rotation of the motor. The multi-way valve is connected to the lifting cylinder 19, the telescopic cylinder 15, the bucket shell cylinder and the mixing motor 16 through a high-pressure oil pipe, and the motor directly controls the first slewing support 12 and the second slewing support 13.

[0033] When it is necessary to complete the feeding process of grabbing and feeding the material into the mixing bucket 10, the second rotary support 13 is remotely controlled by the wireless remote control device to rotate to a suitable position and angle for grabbing sand and gravel, and the second rotary support 13 is remotely controlled to rotate close to the sand and gravel. If the position is suitable, the second rotary support 13 is directly remotely controlled to rotate so that the bottom of the feeding shell bucket 21 is against the sand and gravel. If the position is not suitable, the second rotary support 13 or the telescopic cylinder 15 is controlled to a suitable position, and the second rotary support 13 is controlled to rotate so that the bottom of the feeding shell bucket 21 is against the sand and gravel; when the bottom of the feeding shell bucket 21 is against the sand and gravel, the two shell cylinders are remotely controlled to extend their oil rods at the same time to drive the two feeding shell buckets 21 to rotate and clamp them together to realize the material grabbing work; after the material grabbing work is completed, the second rotary support 13 is remotely controlled to return to the center, and the remote lifting cylinder 19 is extended to drive the mechanical arm 20 to lift the feeding shell bucket 21, and then the two telescopic cylinders 15 are remotely controlled to shorten, and finally the two shell cylinders are remotely controlled to retract at the same time to realize the process of grabbing and feeding the material into the mixing bucket 10.

[0034] When the unloading process needs to be completed, the oil cylinder hinged between the remote control loader and the loader middle arm 17 is extended to drive the mixing bucket 10 to an angle, and at the same time the first slewing support 12 is controlled to rotate counterclockwise to avoid rollover. The unloading process can be realized by the telescopic function of the oil cylinder hinged between the loader and the loader middle arm 17.

[0035] In summary, it can solve the following technical problems:

[0036] 1. Solve the problem that making concrete requires a lot of equipment and workers: Use a wireless control device to control the oil supply of the multi-way valve and the rotation of the motor, so that one person and one machine can complete the operation requirements of feeding, mixing and discharging concrete.

[0037] 2. Solve the problem of concrete feeding: Through the telescopic function of the mechanical arm 20 and the feeding shell bucket 21, cement, sand, stone and other materials from far away are transported to nearby places; the lifting cylinder 19 is controlled to extend the oil rod to drive the mechanical arm 20 to lift the feeding shell bucket 21; the second rotary support 13 is controlled to rotate so that the feeding shell bucket 21 is above the mixing bucket 10; when the material shell bucket is above the mixing bucket 10, the oil cylinders of the two shell cylinders are remotely controlled to retract at the same time, thereby realizing the feeding process of grabbing the material and feeding it into the mixing bucket 10.

[0038] Furthermore, a protective net 11 is provided on the mixing bucket 10, and the protective net 11 is slidably arranged on the mixing bucket 10, and in the sliding direction, a first elastic member is provided between the protective net 11 and the mixing bucket 10; it also includes a transmission member 3 for transmitting power between the feeding shell bucket 21 and the protective net 11; during the opening stroke of the feeding shell bucket 21, the protective net 11 vibrates based on the power of the feeding shell bucket 21.

[0039] Specifically, in the process of concrete raw materials falling from the feeding shell bucket 21 to the mixing bucket 10, the protective net 11 can prevent people from falling or extending their limbs into the mixing bucket 10, so the mesh should not be too large, that is, while people will not fall into the mixing bucket 10, people's limbs are not allowed to pass through the mesh. However, when a large amount of raw materials fall on the protective net 11, it is difficult for the raw materials to pass through the protective net 11 quickly, and some of the raw materials may not be able to fall on the protective net 11. In addition, the concrete raw materials will clump during the stacking process. Obviously, it is more difficult for the raw materials to pass through the protective net 11 into the mixing bucket 10.

[0040] Therefore, in this embodiment, in order to solve the above-mentioned problem, the protective net 11 is slidably arranged on the mixing bucket 10, and after the feeding shell bucket 21 clamps a certain amount of concrete raw materials to just above the center position of the mixing bucket 10, the two fan-shaped buckets are gradually opened under the drive of the shell bucket cylinder 22, and the concrete raw materials inside them fall down, wherein the arrangement of the transmission member 3 can transmit power to the protective net 11 during the opening process of the feeding shell bucket 21, so that the protective net 11 vibrates on the mixing bucket 10, and the function realized by the transmission member 3 is that it can be driven by the feeding shell bucket 21 during the opening process of the feeding shell bucket 21. Each bucket is intermittently moved, and the transmission member 3 can be a strip plate with a plurality of protrusions, and the strip plate is fixedly connected to the protective net 11. During the movement of each bucket of the feeding shell bucket 21, each protrusion is moved in turn, and then the moving force is transmitted to the protective net 11. The protective net 11 slides on the mixing bucket 10 based on this moving force, and the protective net 11 will generate a force on the first elastic member when sliding. After the moving force disappears, the resilience of the first elastic member drives the protective net 11 to reset, so that the protective net 11 will frequently reciprocate to form a vibration effect, thereby vibrating and screening the concrete raw materials.

[0041] The beneficial effect of this embodiment is that the protective net 11 is arranged to slide on the mixing bucket 10, and the first elastic member is subjected to the force of the feeding shell bucket 21 when it is unfolded to cause elastic change, so that the protective net 11 vibrates, which has a vibration and crushing effect on the agglomerated concrete raw materials. After the concrete raw materials falling on the protective net 11 are vibrated, it is easier to break away from the protective net 11 and fall into the mixing bucket 10.

[0042] Preferably, the protective net 11 includes a plurality of longitudinal support rods 110 and transverse support rods 111 arranged in a criss-cross pattern, and the transverse support rods 111 are arched in an arc shape in a direction away from the mixing bucket 10, and a plurality of longitudinal support rods 110 are evenly arranged on the arc-shaped trajectory of the transverse support rods 111; it also includes two main support rods 112 slidably arranged on the mixing bucket 10, the two main support rods 112 are disposed at both ends of the plurality of transverse support rods 111, and the plurality of transverse support rods 111 are fixedly connected to the two main support rods 112.

[0043] Specifically, two main support rods 112 support the entire protection net 11, and the transverse support rods 111 are arched in an arc shape in the direction away from the mixing bucket 10, that is, they are arched upwards. The purpose is that when a large amount of concrete raw materials fall onto the protection net 11 or fall onto the protection net 11 suddenly, the protection net 11 is impacted by the concrete raw materials. The upward arched structure can strengthen the strength of the protection net 11, and prevent the protection net 11 from being deformed downward under the impact, or even contacting the mixer, so that the mixing operation of the concrete raw materials cannot be carried out. The sliding direction of the two main support rods 112 on the mixing bucket 10 should be consistent with the direction in which the protrusion is pushed when the feeding shell bucket 21 is opened in the aforementioned embodiment. If the two main support rods 112 are arranged to slide on the mixing bucket 10 along the longitudinal direction, the opening direction of the feeding shell bucket 21 is along the longitudinal direction. If the two main support rods 112 are arranged to slide on the mixing bucket 10 along the transverse direction, the opening direction of the feeding shell bucket 21 is along the transverse direction. The specific arrangement of the two main support rods 112 on the mixing bucket 10 can be set according to actual needs.

[0044] Furthermore, the plurality of longitudinal support rods 110 are arranged to slide transversely on the plurality of transverse support rods 111, and the plurality of longitudinal support rods 110 are divided into two groups with the middle position as a dividing line, and a second elastic member is provided between two longitudinal support rods 110 at adjacent positions in each group, and the transmission member 3 is connected to the longitudinal support rod 110 at the middle position in each group, and the longitudinal support rod 110 close to the middle position of the protective net 11 in the transverse direction does not move transversely with the other longitudinal support rods 110.

[0045] Specifically, each longitudinal support rod 110 is provided with a sliding opening corresponding to the plurality of transverse support rods 111, so that the longitudinal support rod 110 can slide on the transverse support rod 111. Correspondingly, the mixing bucket 10 is provided with a sliding groove 113 at both ends of the longitudinal support rod 110. A plurality of sliders 114 are arranged in the sliding groove 113 to slide along the track direction of the transverse support rod 111. A second elastic member is provided between two sliders 114 at adjacent positions. Each of the two ends of each longitudinal support rod 110 corresponds to a slider 114, and Each support rod is arranged to slide longitudinally on the corresponding slider 114. In the present embodiment, the plurality of longitudinal support rods 110 are divided into two groups, with the longitudinal center line of the protective net 111 as the dividing line. The four sliders 114 (each longitudinal support rod 110 is provided with sliders 114 at both ends) close to the dividing line cannot slide along the track of the transverse support rod 111 in their respective corresponding slide grooves 113, that is, the two longitudinal support rods 110 close to the middle position of the protective net 11 in the transverse direction do not move laterally with the other longitudinal support rods 110.

[0046] The transmission member 3 is connected to the longitudinal support rod 110 located in the middle position of each group. In this way, when the transmission member 3 transmits the power of the opening of the feeding shell bucket 21 to the protective net 11, the longitudinal support rod 110 located in the middle position of each group will drive the distance between the longitudinal support rods 110 on one side of the longitudinal center dividing line of the protective net 11 to gradually increase (such as the distance between adjacent longitudinal support rods 110 changes from 1 to 1.5), while the distance between the longitudinal support rods 110 on the other side gradually decreases (such as the distance between adjacent longitudinal support rods 110 changes from 1 to 0.5). Under the action of the rebound force of the first elastic member, the longitudinal support rod 110 located in the middle position will drive the longitudinal support rod 110 close to the longitudinal center dividing line of the protective net 11 The distance between the longitudinal support rods 110 on one side gradually decreases (such as the distance between adjacent longitudinal support rods 110 changes from 1.5 to 1), while the distance between the longitudinal support rods 110 on the other side gradually increases (such as the distance between adjacent longitudinal support rods 110 changes from 0.5 to 1). The advantage of such a setting is that the longitudinal support rods 110 located in the middle position will drive the longitudinal support rods 110 part close to the longitudinal center dividing line of the protective net 11, mainly the position where the concrete raw materials pass. The distance between adjacent longitudinal support rods 110 becomes larger, which is conducive to the passage of the concrete raw materials. The change in size can not only achieve the purpose of vibrating and crushing the agglomerated concrete raw materials, but also prevent the mesh of the protective net 11 from getting stuck.

[0047] Preferably, the transmission member 3 includes two supports 30 fixedly connected to the longitudinal support rod 110 located in the middle position of each group of longitudinal support rods 110, the two supports 30 are symmetrically arranged in the longitudinal direction, each support 30 is provided with a toggle rack 31, and each bucket of the feeding shell bucket 21 is fixedly connected to two first toggle rods 32. During the opening stroke of the feeding shell bucket 21, the two first toggle rods 32 on each bucket toggle the two toggle racks 31 at the corresponding positions; the main support rod 112 is arranged to slide longitudinally on the mixing bucket 10, and the teeth of the toggle rack 31 are parallel to the longitudinal direction; the teeth of the two corresponding toggle racks 31 in the longitudinal direction are staggered in the transverse direction.

[0048] Specifically, two main support rods 112 are slidably arranged on the mixing bucket 10, and multiple longitudinal support rods 110 are slidably arranged on multiple transverse support rods 111. The sliding direction of the main support rod 112 is parallel to the longitudinal direction, and the tangent direction of the sliding trajectory of the longitudinal support rod 110 is perpendicular to the longitudinal direction, that is, when each first toggle rod 32 toggles the toggle rack 31 at the corresponding position, its toggle direction should be basically parallel to the transverse direction. At this time, it can be achieved to drive the multiple longitudinal support rods 110 to change the mesh size in the sliding direction. The teeth of the rack are arranged to be parallel to the longitudinal direction. When the first toggle rod 32 toggles the corresponding rack, since the tooth shape is similar to an isosceles triangle structure, the first toggle rod 32 will generate forces in both the transverse and longitudinal directions when toggling the teeth. When the first toggle rod 32 is not disengaged from the teeth, the longitudinal support rod 110 connected to the support 30 not only tends to slide along the trajectory of the transverse support rod 111, but also tends to push the transverse support rod 111 to move in the longitudinal direction. The two toggle racks 31 corresponding to the same longitudinal support rod 110 can also be arranged so that the teeth are staggered in the transverse direction. The two first toggle rods 32 located on each bucket of the feeding shell bucket 21 can toggle the corresponding toggle racks 31 at intervals. The advantage of such an arrangement is that the protective net 11 can realize the change of the transverse mesh size based on the power of the opening of the feeding shell bucket 21. In combination with the reciprocating movement in the longitudinal direction, the change of the mesh size can prevent material jamming while screening the concrete raw materials, so as to improve the passability of the concrete raw materials.

[0049] Preferably, during the opening stroke of the feeding shell bucket 21, each first toggle rod 32 sequentially toggles each tooth of the corresponding toggle rack 31; specifically, in the aforementioned embodiment, the operation of the device is achieved remotely and wirelessly by using a remote control. During the opening process of the feeding shell bucket 21, if the first toggle rod 32 is required to keep toggling the corresponding toggle rack 31, the feeding shell bucket 21 needs to be opened while being close to the protective net 11. The moving trajectory of each bucket of the feeding shell bucket 21 is arc-shaped, and the distance control between it and the protective net 11 is undoubtedly brought by the operator. Therefore, preferably, when the feeding shell bucket 21 is needed to feed the concrete raw materials to the mixing bucket 10, the distance between the feeding shell bucket 21 and the protective net 11 can be set, that is, after the distance between the feeding shell bucket 21 and the protective net 11 reaches the set value, the swing center of each bucket of the feeding shell bucket 21 is basically fixed, then the toggle rack 31 can also be set to a long arc shape, and the center of the toggle rack 31 coincides with the swing center of each bucket of the feeding shell bucket 21, then in each bucket swinging process, the first toggle rod 32 will never be separated from the corresponding toggle rack 31.

[0050] Furthermore, when the first toggle rod 32 sequentially toggles each tooth on the corresponding toggle rack 31 , when the first toggle rod 32 continues to move after being disengaged from the previous tooth, the next tooth hits the first toggle rod 32 under the rebound force of the second elastic member.

[0051] Specifically, the connection between the feeding shell bucket 21 and the mechanical arm 20 is a flexible connection, which reduces shock without affecting the opening and closing of the feeding shell bucket 21. The flexible connection is a prior art and will not be described in detail. In the process of the feeding shell bucket 21 opening and unloading, the concrete raw material will partially adhere to the inner wall of the feeding shell bucket 21, and the feeding shell bucket 21 needs to be opened to a particularly large angle before it is likely to fall off. Therefore, in this embodiment, the distance between the two teeth at adjacent positions on each toggle rack 31 is appropriately increased, and the length of the teeth is appropriately increased, that is, the first toggle rod 32 is increased to toggle the corresponding toggle rack The moving distance of the rack 31 will increase accordingly when the mesh through which the concrete raw material passes. Under the action of the rebound force of the second elastic member, the reset distance of each shifting rack 31 will also increase. In this way, after the first shifting rod 32 is disengaged from the previous tooth, the next tooth will move in the opposite direction and hit the first shifting rod 32. That is, when the first shifting rod 32 shifts the shifting rack 31 at the corresponding position, the shifting rack 31 will also use the rebound force of the second elastic member to reversely hit the first shifting rod 32, so that the feeding shell 21 vibrates, thereby basically solving the problem of concrete raw materials adhering to the inner wall.

[0052] Preferably, each of the supports 30 is provided with a correction block 4, and two corresponding correction blocks 4 in the longitudinal direction are symmetrically arranged, and adjacent first wedge surfaces 40 and second wedge surfaces 41 are provided on the correction blocks 4; when the first wedge surface 40 squeezes the corresponding first toggle rod 32, the feeding shell bucket 21 is subjected to a lateral thrust, and when the second wedge surface 41 squeezes the corresponding first toggle rod 32, the feeding shell bucket 21 is subjected to a longitudinal thrust.

[0053] Specifically, it can be known from the aforementioned embodiments that the toggle rack 31 is fixedly connected to the longitudinal support rod 110 located in the middle position of each group, so that each time the feeding shell bucket 21 feeds the material to the top of the protective net 11, the first toggle rod 32 and the corresponding toggle rack 31 must be basically aligned in position to achieve the vibration of the protective net 11 and the change in the size of the mesh. Therefore, in this embodiment, a correction block 4 is provided on each support 30, and a first wedge surface 40 and a second wedge surface 41 are provided on the correction block 4. The first wedge surface 40 and the second wedge surface 41 are adjacent to each other, that is, during the contact between the first toggle rod 32 and the first wedge surface 40, the first wedge surface 40 gives the first toggle rod 32 a lateral thrust, and during the contact between the first toggle rod 32 and the second wedge surface 41, the second wedge surface 41 The shaped surface 41 gives the first toggle rod 32 a longitudinal thrust. When the first toggle rod 32 contacts the first wedge surface 40 and the second wedge surface 41 on the corresponding correction block 4 at the same time, the first toggle rod 32 will drive the bucket connected thereto to move toward the position corresponding to the toggle rack 31. Therefore, when the personnel wirelessly controls the feeding shell bucket 21 to move above the protective net 11 through the remote control and the position is roughly aligned with the four toggle racks 31, the feeding shell bucket 21 will contact the four correction blocks 4 in the process of moving down and approaching the protective net 11. The first wedge surface 40 and the second wedge surface 41 on the correction block 4 can be set larger accordingly, so as to better correct the position of the feeding shell bucket 21 to be basically aligned with the four toggle racks 31 (without affecting subsequent toggle).

[0054] Furthermore, each bucket of the feeding shell bucket 21 is swingably provided with an auxiliary bucket 23, the auxiliary bucket 23 is sleeved on the outer surface of the feeding shell bucket 21, and a third elastic member is provided at the swing connection between the two. Under the elastic force of the third elastic member, the auxiliary bucket 23 has a tendency to never swing with the feeding shell bucket 21. Each auxiliary bucket 23 is provided with two second toggle rods 24. During the opening stroke of the feeding shell bucket 21, the two second toggle rods 24 toggle the toggle racks 31 at corresponding positions; the correction block 4 is on the moving path of the second toggle rod 24. When the second toggle rod 24 contacts the correction block 4, the feeding shell bucket 21 continues to open, and the auxiliary bucket 23 is hindered by the correction block 4 and swings relative to the feeding shell bucket 21 to limit the discharge amount of concrete raw materials in the feeding shell bucket 21.

[0055] Specifically, when a certain amount of concrete raw materials are placed in the feeding shell bucket 21, as the feeding shell bucket 21 opens wider and wider, the concrete raw materials tend to fall in large quantities at one time, which not only affects the concrete raw materials passing through the protective net 11, but also has an impact on the protective net 11, seriously causing the protective net 11 to be concave and deformed. The problem caused by this is that the subsequent first toggle rod 32 cannot contact the corresponding toggle rack 31, and the concrete raw materials falling on the protective net 11 cannot fall into the mixing bucket 10. Therefore, in this embodiment, an auxiliary bucket 23 is installed on each bucket of the feeding shell bucket 21, and the auxiliary bucket 23 is swingably arranged on the corresponding bucket of the feeding shell bucket 21, and the elastic force of the third elastic member is used to ensure that when the auxiliary bucket 23 is not affected by external force, the angle between the two will not change, that is, when the two buckets of the feeding shell bucket 21 are completely closed, the two auxiliary buckets 23 also abut against each other, but in the process of opening the two buckets, if the auxiliary bucket 23 is not affected by external force, the position between the auxiliary bucket 23 and the bucket of the feeding shell bucket 21 will not change. When the two auxiliary buckets 23 are affected by external force and do not move with the feeding shell bucket 21, the discharge diameter can be controlled. Therefore, the position of each correction block 4 is on the moving path of the second toggle rod 24 set on each auxiliary bucket 23, and the stiffness coefficient of the third elastic member is greater than the stiffness coefficient of the second elastic member, that is, when the auxiliary bucket 23 moves with the feeding shell bucket 21, the second toggle rod 24 can toggle the toggle rack 31 like the first toggle rod 32, and when the correction block 4 prevents the second toggle rod 24 from continuing to toggle the corresponding toggle rack 31, as the feeding shell bucket 21 continues to open, the auxiliary bucket 23 no longer continues to swing with the feeding shell bucket 21, but the two swing relative to each other, that is, at this time the position of the auxiliary bucket 23 can be regarded as stationary, and the opening angle between the two buckets of the feeding shell bucket 21 is still increasing, then the distance between the two auxiliary buckets 23 basically does not change significantly, and at this time the discharge diameter of the concrete raw material is controlled, thereby realizing the control of the discharge amount and avoiding a large amount of concrete raw materials from falling at one time.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the protection of the present invention.
