Description

Technical Field

[0001] This utility model relates to the field of construction layout technology, specifically a powder layout ink fountain for construction sites. Background Technology

[0002] Currently, construction sites often require the use of white lime powder to mark lines to separate construction areas, office areas, material storage areas, etc. During the operation, the operator holds a "long-handled large ladle" to scoop out white lime powder, then slides the back of the ladle against the ground, and shakes the white lime powder off the ladle by rotating the wrist. The operator marks the lines by coordinating his own movements with the movement of his arm.

[0003] However, using a long-handled ladle for line marking is rather rudimentary. The width, horizontal / vertical accuracy, and curvature of the lines require a high level of experience from the operator, and it is very easy to produce problems such as skewed or twisted lines. On the other hand, the amount of lime powder that a long-handled ladle can hold at one time is limited. When marking large-scale lines on construction sites, it is common to run out of lime powder before a line is finished. If the long-handled ladle is used to scoop out more lime powder, it is difficult to maintain the arm posture of the previous line marking, resulting in inconsistencies in the curvature, verticality, and horizontality of the lines before and after the previous line marking.

[0004] Therefore, how to design a powder-based chalk line marker for construction sites that is suitable for large-scale line-laying construction on construction sites has become a technical problem that urgently needs to be solved by people in this field. Utility Model Content

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this utility model is to provide a powder-based chalk line marker for construction sites. This chalk line marker effectively solves the problem of intermittent line marking and inconsistent standards after frequent addition of quicklime powder, thereby improving the accuracy of line marking on construction sites.

[0006] To address the aforementioned problems, this utility model provides a powder marking ink fountain for construction sites, comprising a housing and a pusher wheel; the pusher wheel is coaxially and rotatably inserted into one end of the housing, a hopper is fixedly and connected to the middle of the housing, a powder outlet is opened at the lower part of the other end of the housing, and a hand handle is radially fixedly connected to the axial outer wall of the housing; the axle of the pusher wheel is axially inserted into the inside of the housing, and a spiral plate is fixedly provided on the outside of the axle of the pusher wheel; the spiral plate is powered by the pusher wheel and the axle, and the spiral plate pushes the powder from the hopper outlet to the powder outlet of the housing.

[0007] Preferably, the axle of the pusher wheel is a stepped axle;

[0008] The axial end face of the large diameter end of the stepped shaft is coaxially fixed to the pusher, and the circumferential outer wall of the large diameter end of the stepped shaft is sealed and rotatably inserted into the circumferential inner wall of one end of the housing.

[0009] The small-diameter end of the stepped shaft rotates circumferentially and is axially limited and connected to the other side wall of the housing.

[0010] Preferably, a locking pin is radially inserted into the small-diameter end of the stepped shaft. The outer periphery of the locking pin abuts against the outer wall of one end of the housing, and the locking pin provides axial restraint for the housing and the small-diameter end of the stepped shaft.

[0011] Preferably, the top of the hopper is open, and the bottom outlet of the hopper is connected to the inside of the shell.

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] This utility model discloses a powder-based line-laying ink fountain for construction sites. The operator grips the handle and walks forward or backward, providing forward power to the housing and pusher wheel. The rotation of the pusher wheel provides rotational power to the stepped shaft and spiral plate. The housing is connected to the powder outlet and the hopper outlet, serving as a temporary storage cavity for the quicklime powder. The quicklime powder is quantitatively dispensed from the housing outlet as the spiral plate rotates, thus enabling long-distance, large-area on-site line-laying construction.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] Combination Figures 1-2 This utility model discloses a powder marking ink fountain for construction sites, comprising a housing 3 and a pusher 4; the pusher is coaxially and rotatably inserted into one end of the housing, a hopper 2 is fixedly and connected to the middle of the housing, a powder outlet 5 is opened at the lower part of the other end of the housing, and a hand handle 1 is radially fixedly connected to the outer wall of the housing; the axle of the pusher is axially inserted into the inside of the housing, and a spiral plate 8 is fixedly provided on the outside of the axle of the pusher; the spiral plate is provided with rotational power by the pusher and the axle, and the spiral plate pushes the powder from the outlet of the hopper to the outlet of the housing.

[0022] Preferably, the axle of the push wheel is a stepped axle 7;

[0023] The axial end face of the large diameter end of the stepped shaft is coaxially fixed to the pusher, and the circumferential outer wall of the large diameter end of the stepped shaft is sealed and rotatably inserted into the circumferential inner wall of one end of the housing.

[0024] The small-diameter end of the stepped shaft rotates circumferentially and is axially limited and connected to the other side wall of the housing.

[0025] Preferably, a locking pin 6 is radially inserted into the small-diameter end of the stepped shaft. The outer periphery of the locking pin abuts against the outer wall of one end of the housing, and the locking pin provides axial restraint for the housing and the small-diameter end of the stepped shaft.

[0026] Preferably, the top of the hopper is open, and the bottom outlet of the hopper is connected to the inside of the shell.

[0027] In addition, the preferred embodiment of the present invention is that the shell is made of transparent hard plastic material, so that the operator can observe the amount of powder in the hopper and inside the shell during the feeding process, thereby maintaining the continuity of powder output from the powder outlet.

[0028] The working principle of this utility model is as follows:

[0029] This utility model relates to a powder-based marker for construction sites. During operation, quicklime powder is manually added from the top opening of the hopper. After the quicklime powder falls into the housing, the operator pushes the housing and pusher wheel. When the pusher wheel rolls in contact with the ground, the spiral plate on the stepped shaft quantitatively pushes the quicklime powder inside the housing to the powder outlet of the housing, thereby enabling long-distance, large-area construction marking.

[0030] It is important to note that, to ensure the coaxiality of the pusher and the housing, the large-diameter end of the stepped shaft radially fits against the inner wall of the housing's arc surface. This serves two purposes: firstly, it seals the housing and the large-diameter end of the stepped shaft, preventing quicklime powder from scattering from the end connecting the housing to the pusher; secondly, it provides coaxial constraint for the stepped shaft. Simultaneously, the small-diameter end of the stepped shaft rotates and penetrates the housing, then radially engages via a locking pin. This achieves axial positioning of the stepped shaft and the housing, ensuring coaxial constraint between them. The powder falling speed during line feeding is related to the operator's pushing speed of the pusher, while the powder falling width and amount are related to the pusher's rolling speed and the screw pitch of the spiral plate.

[0031] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
