Technical Field

[0001] The utility model relates to the technical field of land planning, in particular to a wire-retracting and -releasing device for land planning. Background Art

[0002] In land planning, the role of wire-retracting devices is very critical. They are mainly used to ensure the accuracy and efficiency of land measurement. Laying out the wires is an important step in determining the boundaries and scope of the land. One end of the ground wire is fixed inside the land by a fixing nail, and the wire-retracting device is pushed to lay the ground wire on the surface for laying out the wires.

[0003] In land greening planning, workers will spread lime on the ground line. The lime line can clearly mark the boundaries and planning lines of the land, providing visual guidance for construction layout.

[0004] In the prior art, after workers have finished laying the ground wires using the wire-retracting and -releasing device, they manually spray lime along the ground wires, which is time-consuming and labor-intensive. Utility Model Content

[0005] Aiming at the defect of low efficiency of manual lime laying in the prior art, the utility model provides a wire-retracting and releasing device for land planning, which can achieve the effect of high-efficiency lime laying.

[0011] In the utility model, the protective cover ensures the lime capacity and reduces the squeezing force of the lime on the ground wire, thereby ensuring that the ground wire can slide normally inside the processing chamber.

[0012] Preferably, the first through hole is in contact with the outer surface of the ground wire.

[0013] In the utility model, the first through hole is attached to the outside of the ground wire, so that the lime inside the processing cavity can be blocked to prevent it from flowing into the cavity through the first through hole.

[0014] Preferably, the second through hole is larger than the first through hole, and the second through hole is connected to the main frame, and the ground wire slides at the connection point between the second through hole and the main frame.

[0019] In the utility model, the receiving hole ensures the accuracy of adjusting the direction of the snake neck tube and ensures that the lime can flow out normally, thereby further improving the accuracy of the direction adjustment of the device.

[0020] Preferably, the extended end of the ground wire is fixedly connected with a fixing nail, and the bottom of the fixing nail can completely cover the opening of the through cavity.

DETAILED DESCRIPTION

[0029] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0030] Example 1

[0031] like Figure 1-3 As shown, the present embodiment provides a wire-retracting and -releasing device for land planning, including a main frame 100 for moving on the ground surface, a handle being provided at the main frame 100, a cavity 210 being provided inside the main frame 100, a spool 260 with a ground wire 220 wound around one end of the cavity 210 close to the handle being provided, a processing box 230 being provided at one end of the cavity 210 away from the handle, a processing cavity 310 for placing lime being formed inside the processing box 230, and processing channels for sliding the ground wire 220 being formed at the front and rear ends of the processing cavity 310.

[0032] In this embodiment, the extended end of the ground wire 220 is fixed on the ground surface, and the main frame 100 is pulled to move on the ground. The ground wire 220 inside the cavity 210 will extend outside the main frame 100. During the extension process, the ground wire 220 will pass through the processing channel of the processing cavity 310. The lime inside the processing cavity 310 will adhere to the ground wire 220, and the ground wire 220 adhered to the lime part will slide out of the main frame 100. After the ground wire 220 slides out, it contacts the ground. The lime adhered to the surface of the ground wire 220 will mark the ground wire path. During this period, there is no need to manually sprinkle lime, which improves the convenience of measurement in the process of land greening planning.

[0033] Among them, the ground line 220 is touched to the ground for marking. Compared with the traditional manual placement of lime, the lime is placed closer to the ground line 220 and has higher accuracy, which improves the accuracy of subsequent construction by staff.

[0034] Combination Figure 2-3 As shown, in this embodiment, the processing channel is located at the front and rear ends of the processing cavity 310 and is respectively provided with a first through hole 250 and a second through hole 320; the processing cavity 310 is located between the first through hole 250 and the second through hole 320 and is provided with a protective cover 330; the outside of the protective cover 330 is provided with a third through hole 340; the first through hole 250 is in contact with the outer surface of the ground wire 220.

[0035] In this embodiment, the ground wire 220 enters the processing chamber 310 through the first through hole 250, and the lime inside the processing chamber 310 enters the protective cover 320 through the third through hole 340 outside the protective cover 320. The lime flowing inside the protective cover 320 will smear the ground wire 220. The smeared ground wire 220 then slides out of the processing chamber 310 through the second through hole (320). When the lime inside the protective cover 320 is reduced, it is replenished again through the third through hole 340. The protective cover 320 reduces the lime capacity while reducing the squeezing force of the lime on the ground wire 220, ensuring that the ground wire 220 can slide normally inside the processing chamber 310. When the ground wire 220 enters the processing chamber 310 through the first through hole 250, the first through hole 250 is attached to the outside of the ground wire 220 to block the lime inside the processing chamber 310, preventing it from flowing into the cavity 210 through the first through hole 250.

[0036] Combination Figure 2-3 As shown, in this embodiment, the second through hole 320 is larger than the first through hole 250, and the second through hole 320 is connected to the main frame 100, and the ground wire 220 slides at the connection between the second through hole 320 and the main frame 100; the connection between the second through hole 320 and the main frame 100 is fixedly connected with a bendable snake neck tube 110.

[0037] In this embodiment, the second through hole 320 is larger than the first through hole 250. During the outward extension of the ground wire 220, part of the lime in the processing chamber 310 can be dispersed through the main frame 100, thereby increasing the amount of lime sprayed by the device and making it easier for staff to find traces of lime. During the dispersion of lime through the main frame 100, the snake neck tube 110 will adjust the spraying direction of the lime so that it is consistent with the moving direction of the ground wire 220, thereby improving the accuracy of the lime spraying.

[0038] The above-mentioned snake-neck tube 110 can adjust the direction of lime spraying, but considering that during the actual operation, a gap must be left between the snake-neck tube 110 and the ground wire 220 for the lime to pass through. When the direction of the ground wire 220 is fine-tuned, the inclination direction of the snake-neck tube 110 will produce an error with the extension direction of the ground wire 220. Therefore, the problem is solved through the following embodiment.

[0039] Combination Figure 3-5As shown, in this embodiment, a fixing sleeve 410 is provided on the outside of the snake neck tube 110, a through cavity 510 is formed inside the fixing sleeve 410, a plurality of support frames 520 are fixedly connected to the inner wall of the through cavity 510, and a receiving hole 530 for sliding of the ground wire 220 is formed at the connection between the support frames 520, and overflow ports 540 for lime to pass through are left on both sides of the support frames 520.

[0040] During the tilting process of the ground wire 220 inside the accommodating hole 530 in this embodiment, the support frame 520 will be driven to move, and the support frame 520 will drive the fixing sleeve 410 to move, thereby adjusting the tilting direction of the snake neck tube 110. At the same time, the lime flows out through the overflow port 540 and is sprayed on the ground. The accommodating hole 530 ensures the accuracy of the direction adjustment of the snake neck tube 110 while ensuring that the lime can flow out normally, thereby further improving the accuracy of the direction adjustment of the device.

[0041] Combination Figure 2-5 As shown, in this embodiment, the extending end of the ground wire 220 is fixedly connected to a fixing nail 420 , and the bottom of the fixing nail 420 can completely cover the opening of the through cavity 510 .

[0042] After the ground wire 220 is recovered in this embodiment, the bottom of the fixing nail 420 will seal the surface of the through cavity 510, so as to prevent the lime inside the through cavity 510 from overflowing when not in use, thereby improving the practicality of the device.

[0043] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
