Description

TECHNICAL FIELD

[0001] The application relates to the technical field of cement mixing equipment, in particular to a device for mixing cement mortar on site. BACKGROUND

[0002] At present, cement mortar is prepared by mixing cement, fine aggregate and water in a certain proportion. After mixing, the cement can harden in air or water and tightly cement the sand and stone together. The hardened cement not only has high strength characteristics, but also can effectively resist the erosion of fresh water and salt water environment. Therefore, as a kind of important cementing material, cement has been widely and durably applied in many fields such as civil engineering, water conservancy construction, national defense facilities and the like.

[0003] Super early strength cement mortar is a kind of cement mortar with super high early strength, which is usually used in occasions requiring rapid hardening. It is prepared by adding specific early strength agent or other chemical additives to ordinary cement mortar to obtain higher early strength.

[0004] In the construction process, in order to facilitate the construction operation, the mortar required for building is usually prepared and mixed by adding water on site. The existing cement mortar mixer has the problems of small mixing range and uneven mixing, resulting in low mixing efficiency. The super early strength cement has a fast hardening time, which further exacerbates the time urgency in the construction process. If the mixing is not sufficient, not only the uniformity and strength of the cement mortar will be affected, but also due to the rapid hardening characteristics of the super early strength cement, part of the cement mortar may have started to harden before the construction operation is completed, which seriously affects the engineering quality and progress.

[0005] In the related art, the cement mortar mixing device mainly has two forms: a single mixer or a mixer and a mixing barrel integrated design. The single mixer is small in size and convenient to carry, and is suitable for mixing a small amount of cement mortar. However, the mixing rod of the single mixer is short and narrow, and the specifications are single, so the mixing effect is poor. The integrated mixing device is large in size and has good mixing effect, but it is difficult to carry and has a high material waste ratio. CONTENT OF THE INVENTION

DETAILED DESCRIPTION

[0025] The application will be further described in detail below with reference to the accompanying drawings. Figures 1-5 The application will be further described in detail below with reference to the accompanying drawings.

[0026] The embodiment of the application discloses a device for stirring cement mortar on site, referring to Figure 1 and Figure 2In the embodiment, the device comprises a vertical rod 1, a double-circular stirring structure 2, a double-hill reinforced stirring structure 3 and a connecting piece. The vertical rod 1 is made of carbon steel and the top end of the vertical rod 1 is connected with an external motor. When the motor is started, the vertical rod 1 is driven to rotate. The double-circular stirring structure 2 is installed at the middle part of the vertical rod 1 to exchange and stir the upper and lower layers of cement mortar.

[0027] Specifically, referring to Figure 2 and Figure 3 In the embodiment, the double-circular stirring structure 2 comprises a main circular stirring ring 21 and a secondary circular stirring ring 22. The main circular stirring ring 21 and the secondary circular stirring ring 22 are both made of carbon steel and are installed at the outer side of the middle part of the vertical rod 1. The diameter of the main circular stirring ring 21 is larger than that of the secondary circular stirring ring 22 and the secondary circular stirring ring 22 is located at the inner side of the main circular stirring ring 21.

[0028] Therefore, by setting the structure of the main circular stirring ring 21 and the secondary circular stirring ring 22 cooperating with each other, when the vertical rod 1 rotates, the main circular stirring ring 21 and the secondary circular stirring ring 22 are simultaneously driven to rotate, so as to realize the up-and-down stirring of the cement mortar, thereby ensuring the uniform distribution of the upper and lower layers of materials and avoiding the problem of uneven stirring of the local cement mortar.

[0029] Meanwhile, referring to Figure 2 In the embodiment, the double-hill reinforced stirring structure 3 is provided with a plurality of double-hill reinforced stirring structures 3 which are symmetrically arranged at the outer side of the bottom end of the vertical rod 1. The connecting piece is provided with a plurality of connecting pieces which are arranged between the double-hill reinforced stirring structure 3 and the vertical rod 1, so as to stably install the double-hill reinforced stirring structure 3 at the outer side of the bottom end of the vertical rod 1, thereby realizing the uniform stirring of the same layer of cement mortar.

[0030] When the motor is started, the output end of the motor drives the vertical rod 1 to rotate. During the rotation of the vertical rod 1, the double-circular stirring structure 2 and the double-hill reinforced stirring structure 3 are simultaneously driven to rotate, thereby realizing the effective stirring of the cement mortar. When in use, the liquid level of the cement mortar should not exceed the height of the double-circular stirring structure 2, so as to ensure the contact between the mortar and the stirring structure.

[0031] The structure of the double-hill reinforced stirring structure 3 and the connecting piece will be described in detail as follows:

[0032] Specifically, referring to Figure 2 and Figure 3In the embodiment, the double-hill reinforced stirring structure 3 comprises a transverse reinforcing rod 31, an inner vertical reinforcing rod 32 and an outer vertical reinforcing rod 33. The transverse reinforcing rod 31, the inner vertical reinforcing rod 32 and the outer vertical reinforcing rod 33 are all made of carbon steel. One end of the transverse reinforcing rod 31 is fixedly installed on the outer side of the bottom end of the upright rod 1 by a connecting screw, and the transverse reinforcing rod 31 is perpendicular to the upright rod 1. The inner vertical reinforcing rod 32 and the outer vertical reinforcing rod 33 have the same structure, and one end of each of the inner vertical reinforcing rod 32 and the outer vertical reinforcing rod 33 is installed on the outer side of the transverse reinforcing rod 31.

[0033] The transverse reinforcing rod 31, the inner vertical reinforcing rod 32 and the outer vertical reinforcing rod 33 are cooperatively arranged, which can further enhance the overall stirring effect and the stirring intensity, thereby optimizing the mixing uniformity of the cement mortar in the same layer and making the stirring process more efficient.

[0034] Preferably, the upright rod 1, the double-circular stirring structure 2 and the double-hill reinforced stirring structure 3 are all provided with a zinc plating layer. The zinc plating layer can prevent corrosion of the surfaces of the upright rod 1, the double-circular stirring structure 2 and the double-hill reinforced stirring structure 3, thereby prolonging the service life of the upright rod 1, the double-circular stirring structure 2 and the double-hill reinforced stirring structure 3.

[0035] Specifically, referring to Figures 3-5 In the embodiment, the connecting member comprises a connecting screw 4, one end of the connecting screw 4 is fixedly connected with one end of the transverse reinforcing rod 31 of the double-hill reinforced stirring structure 3, and a connecting threaded groove 11 is formed in the outer side of the bottom end of the upright rod 1. The connecting threaded groove 11 is threadedly connected with the connecting screw 4, so that the connecting screw 4 can be screwed into the connecting threaded groove 11, thereby stably installing the double-hill reinforced stirring structure 3 on the outer side of the bottom end of the upright rod 1.

[0036] When the connecting screw 4 is unscrewed from the connecting threaded groove 11 in the opposite direction, the double-hill reinforced stirring structure 3 can be separated from the upright rod 1, thereby dismounting the double-hill reinforced stirring structure 3 from the upright rod 1.

[0037] Preferably, referring to Figure 3 and Figure 5 In the embodiment, a locking assembly is further arranged on the bottom end of the upright rod 1, and the locking assembly cooperates with the connecting screws 4 to further lock and position the connecting screws 4 on the upright rod 1.

[0038] More specifically, in the present embodiment, the locking assembly comprises a locking bottom cover 5, locking rods 51 and fasteners. The locking bottom cover 5 is arranged at the bottom end of the upright rod 1; the locking rods 51 are provided with several ends, which are respectively fixedly installed on one side of the locking bottom cover 5, and several locking grooves 12 are arranged at the bottom end of the upright rod 1, which are respectively matched with the locking rods 51.

[0039] Meanwhile, the locking holes 41 are arranged on the connecting screw rods 4, which are respectively matched with the locking grooves 12 and the locking rods 51 when the connecting screw rods 4 are screwed in the connecting screw grooves 11, so that the locking rods 51 are sequentially inserted into the upright rod 1 and the connecting screw rods 4 along the locking grooves 12 and the locking holes 41, thereby further stably limiting the connecting screw rods 4 in the connecting screw grooves 11.

[0040] In addition, the fasteners are arranged between the locking bottom cover 5 and the upright rod 1 to stably install the locking bottom cover 5 at the bottom end of the upright rod 1. Specifically, the fasteners are fastening countersunk bolts 52, the fastening countersunk holes 53 are arranged in the middle of the locking bottom cover 5, and the fastening screw grooves 13 are arranged in the middle of the bottom end of the upright rod 1, which are threadedly connected with the fastening countersunk bolts 52.

[0041] When the locking bottom cover 5 and the upright rod 1 abut against each other, the fastening countersunk holes 53 and the fastening screw grooves 13 correspond to each other, and then the fastening countersunk bolts 52 are screwed into the fastening screw grooves 13 along the fastening countersunk holes 53, thereby stably installing the locking bottom cover 5 at the bottom end of the upright rod 1, and further locking and limiting the connecting screw rods 4 on the upright rod 1.

[0042] Secondly, referring to Figure 1 and Figure 2 In the present embodiment, the device further comprises a stirring barrel 6, which is a high-density polyethylene open barrel, and the diameter of the bottom end of the stirring barrel 6 is smaller than that of the top end, for containing cement mortar; meanwhile, the maximum diameter of the double-mountain reinforced stirring structure 3: the minimum diameter of the stirring barrel 6 = 2:3; through the design of the stirring barrel 6, it is ensured that the double-mountain reinforced stirring structure 3 can fully act on the cement mortar in the stirring barrel 6, thereby realizing efficient overall stirring.

[0043] In addition, referring to Figure 2 and Figure 3 In the present embodiment, the side wall of the stirring barrel 6 has the same inclination angle as the inclination angles of the inner vertical reinforcing rod 32 and the outer vertical reinforcing rod 33, which can take away the materials gathered at the edge of the stirring barrel 6, thereby achieving the purpose of sufficient stirring.

[0044] Therefore, the scheme of the application can quickly stir the ultra-early-strength water cement mortar uniformly without causing a large amount of material loss by setting the structure of the upright rod 1, the double-circular stirring structure 2, the double-hill reinforced stirring structure 3 and the connecting piece matched with each other, thereby improving the on-site construction efficiency and saving the material cost; and the stirring device is convenient to carry, thereby solving the problems of difficult stirring and poor stirring effect of a single stirrer or difficult carrying and easy material loss of an integrated stirrer in the application field of sewage well repair.

[0045] The above is only the embodiment of the application, and does not limit the patent range of the application, and any equivalent structure or equivalent process transformation or direct or indirect application in other related technical fields by using the content of the application specification and drawings are also included in the patent protection range of the application.
