[0028] Example 1

[0029] The utility model provides a concrete pouring mixing equipment, comprising a mixing tank, a motor arranged on the top of the mixing tank, and a mixing assembly arranged inside the mixing tank and connected to the motor, wherein a feeding pipe 1 with an upward opening is obliquely arranged on the upper end of the side wall of the mixing tank, and a bag breaking assembly is arranged at the opening of the feeding pipe 1; a feeding unit 2 for conveying cement bags to the opening of the feeding pipe 1 is arranged at the side end of the mixing tank.

[0030] In this embodiment, a motor is arranged at the top center of the mixing tank, and the output end of the motor is directly connected to the mixing assembly to ensure that the mixing assembly can mix stably and smoothly; the feed pipe 1 is arranged at the side end of the mixing tank body near the top, and the opening arranged obliquely on the side wall of the tank body and the inclined feed pipe 1 are seamlessly installed to ensure smooth feeding of cement. Compared with the prior art, the mixing equipment provided in this embodiment arranges the mixing assembly and the feed pipe for cement feeding independently in terms of position distribution, without interfering with each other, thus avoiding the occurrence of problems such as complex device components and slow cement feeding speed.

[0031] It is understandable that the bag breaking assembly can be a structure with an electric push rod and a bag breaking knife as disclosed in the prior art CN220313753U, or a combination of other known structures. In this embodiment, the bag breaking assembly is preferably a bag breaking knife 3 arranged on the pipe wall near the opening of the feed pipe 1 and facing the opening of the feed pipe 1. When the cement bag enters the feed pipe 1 to a certain depth, the weight of the cement bag can prompt the bag breaking knife 3 to separate the cement bag for unloading.

[0032] It is worth noting that the mixing device also includes a liquid spraying assembly 4 arranged inside the mixing tank and located at the upper end of the feed port of the feed pipe 1, and a liquid storage tank 5 arranged at the side end of the mixing tank and used to supply liquid to the liquid spraying assembly 4. The liquid spraying assembly 4 is mainly composed of an annular tube with an inner diameter larger than the maximum diameter of the mixing assembly, and the annular tube is connected to the external liquid storage tank 5 through a water pipe. The tube wall of the annular tube is evenly distributed with nozzles for spraying water into the mixing tank, which is used as a quantitative water adding device for cement mixing and also avoids cement dust.

[0033] In this embodiment, the loading unit 2 includes a support frame 201, a base plate 202 arranged on the support frame 201, a loading plate 203 hinged to the end of the base plate 202, a driving member 204 arranged on the support frame 201 and used to drive the loading plate 203 to rotate around the hinge between the base plate 202 and the loading plate 203, and a hanging member 205 arranged on the end of the loading plate 203 away from the base plate 202; the rotation range of the loading plate 203 driven by the driving member 204 is 0~90°.

[0034] Among them, the support frame 201 includes at least one horizontally arranged support plate, the bottom plate 202 is vertically installed on the support plate, and the loading plate 203 rotates around the hinge. When the rotation angle of the loading plate 203 is 0°, it is parallel to the support plate and is used as a platform for placing cement bags, which greatly reduces the difficulty of hanging cement bags and saves time and effort. In the process of gradually rotating the loading plate 203 until 90° and flush with the surface of the bottom plate 202, the loading plate 203 always plays the role of a baffle to prevent excessive shaking of the cement bags.

[0035] As a further preference of this embodiment, the driving member 204 includes a first ear plate 204a arranged on the support frame 201, a second ear plate 204b arranged on the loading plate 203, a first connecting rod 204c having one end hinged to the first ear plate 204a and the other end extending to the second ear plate 204b, and a second connecting rod 204d having one end hinged to the second ear plate 204b and the other end hinged to the first connecting rod 204c.

[0036] It should be noted that the entire drive member 204 needs to be connected to an external drive motor, and the drive motor can be connected to the hinge between the first connecting rod 204c or the second connecting rod 204d and the two ear plates to drive the first connecting rod 204c or the second connecting rod 204d to rotate, or the drive motor can be directly connected to the hinge between the first connecting rod 204c and the second connecting rod 204d to drive the hinge to move up and down. Any of the above methods can achieve the purpose of the drive member 204 driving the loading plate 203 to rotate within the range of 0~90°. The specific implementation method depends on the actual scenario, so it will not be repeated in this embodiment.

[0037] As a further preferred embodiment of the present invention, the hanging member 205 comprises a groove 205a disposed at the upper end of the feeding plate 203, a driving cylinder 205b disposed on the bottom surface of the groove 205a, a hanging plate 205c slidably disposed in the groove 205a and connected to the output end of the driving cylinder 205b, and a hook 205d disposed on the hanging plate 205c. The purpose of such a configuration is to improve the applicability of the present device to the feeding of cement bags of different specifications and sizes, and to prevent the cement bags from being blocked by the body of the feeding pipe 1 during the feeding rotation process.

[0038] The working principle of the device provided in this embodiment is as follows: the external motor starts the driving member to drive the loading plate 203 to maintain an angle of 0°, place the cement bag on the horizontal plane formed by the loading plate 203, and hang the cement bag on the hook 205d. The rotation angle of the loading plate 203 gradually increases. During this process, the end of the cement bag is fixed by the hook 205d, and the loading plate 203 prevents it from shaking excessively. When the loading plate 203 rotates to 90°, the cement bag is just located at the upper end of the opening of the feed pipe 1. At this time, the driving cylinder 205d drives the hanging plate 205c to descend so that the cement bag enters the pipe mouth, and the bag-breaking knife 3 slides to break the cement bag, and the cement enters the mixing tank along the feed pipe 1. When the cement is unloaded, the loading plate 203 rotates back to the 0° state, and the empty cement bag is also driven to the initial position, which is convenient for the staff to remove.

[0041] In this embodiment, the hanging component 205 also includes a fixed plate 205e arranged on the bottom surface of the groove 205a, a limiting slide groove 205f arranged on the fixed plate 205e, and a slide plate 205g arranged on the hanging plate 205c close to one end of the bottom surface of the groove 205a and slidably connected to the limiting slide groove 205f.

[0042] It is worth noting that the fixing plate 205e is centrally mounted on the bottom surface of the groove 205a, and the number of the driving cylinders 205b is two, which are symmetrically mounted at both ends of the fixing plate 205e. The surface of the fixing plate 205e is flush with the surface of the loading plate 203, thereby increasing the effective area for supporting the cement bag. The setting of the limiting slide groove 205f and the slide plate 205g is used to enhance the stability of the lifting and lowering of the hanging plate 205c and improve the load-bearing strength of the hanging plate 205c.

[0043] In this embodiment, the hanging member 205 further includes two limiting slideways 205h arranged on the two inner side walls of the limiting slide groove 205f, and limiting sliders 205i arranged on both sides of the slide plate 205g and respectively connected to the two limiting slideways 205h. The structures of the limiting slideways 205h and the limiting sliders 205i are used to further enhance the stability of the hanging plate 205c when it is lifted and lowered, and to improve the load-bearing strength of the hanging plate 205c.

[0044] In this embodiment, the hanging member 205 further includes a baffle 205j disposed on the side of the opening of the groove 205a close to the feeding pipe 1. The baffle 205j is divided into two pieces, which are symmetrically installed at both ends of the fixing plate 205e to form a finished surface with the surface of the fixing plate 205e, which is used to protect the driving cylinder 205b and further increase the effective area of ​​supporting the cement bag.
