Description

Technical Field

[0001] This utility model relates to a portable distance meter. Background Technology

[0002] The spacing between tobacco seedlings is crucial during transplanting. A reasonable spacing ensures adequate distribution of base fertilizer and promotes normal plant growth. Since the transplanting density of flue-cured tobacco is determined by both row spacing and plant spacing, and the row spacing is already determined when ridging and mulching before transplanting, determining the plant spacing during transplanting is a key step in ensuring optimal transplanting density.

[0003] In existing technologies, there are various types of spacers used for flue-cured tobacco spacing, most of which are circular rolling spacers, such as [CN] An Adjustable Flue-cured Tobacco Transplanting Wheel Spacer - CN209572410U. However, the "marking nails" of these circular rolling spacers are quite sharp and can easily tear the mulch film during operation. There are also traditional insert-type spacers, but they generally do not have a pre-set spacing. Each time, the spacer is positioned along the previous insertion hole. That is, each time, the spacer head can only move laterally to the position of the previous spacer head before inserting to ensure that the previous spacer head opens the holes at equal intervals. This is inefficient and urgently needs improvement. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a portable rangefinder that is not only reasonably structured, but also convenient and efficient.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a portable distance measuring device, including a horizontal support, on which two acupoint cups are sleeved, one of which is fixed to one end of the horizontal support, and the other is slidably connected to the horizontal support and positioned by a radially extending bolt. The top of each acupoint cup is coaxially sleeved on the horizontal support through a sleeve. A through tube is fixed to the top of the sleeve of the acupoint cup fixed to the end of the horizontal support. An L-shaped distance measuring rod passes through the through tube. The horizontal end of the distance measuring rod passes through the through tube and is slidably connected to it and positioned by a radially extending bolt. The vertical end extends vertically downward and is at the same level as the bottom end of the acupoint cup.

[0006] Furthermore, a vertically extending support is fixedly provided in the middle of the horizontal support, and a horizontally extending handle is fixedly provided at the top of the vertical support.

[0007] Furthermore, the acupoint cup is composed of a top sleeve, a middle cup body, and a bottom cone body. The cup body is cylindrical, and the cone body is conical with its tip pointing downwards.

[0008] Furthermore, a limiting slide rail is fixedly provided on the outer side of the horizontal support along its length direction, and a sliding groove is provided on the inner wall of the sleeve of the opening cup that is slidably connected to the horizontal support, which slides in cooperation with the slide rail.

[0009] Furthermore, the sleeve side and the top of the through pipe are provided with through holes for bolts to be inserted, and nuts are fixed on the sleeve and through pipe outside the through holes to facilitate bolt connection.

[0010] Furthermore, a conduit is fixed at the top of the horizontal support near the through pipe, which is at the same level as the through pipe so that the spacer rod can pass through. The conduit and the through pipe are both tubular and coaxially arranged.

[0011] Furthermore, a triangular reinforcing plate is fixedly connected between the vertical frame and the horizontal support.

[0012] Furthermore, the top of the sleeve of the cup that is slidably connected to the horizontal support is provided with a clearance groove for the clearance reinforcement plate.

[0013] Furthermore, the bottom of the vertical section of the spacer is a pointed tip.

[0014] Furthermore, a limiting slide rail is fixedly provided on the horizontal section of the spacer rod along its length direction, and a sliding groove is provided on the inner wall of the through pipe to slide in cooperation with the slide rail.

[0015] Furthermore, the horizontal support and the horizontal section of the spacer rod are both engraved with scale lines along their length.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Compared with ordinary single-plant spacing devices: First, it enhances operational balance; second, it reduces the impact of uneven ridge surfaces; third, it improves work efficiency, doubling the efficiency of the original single-plant spacing device; and fourth, it saves labor time and costs, solving the problems of labor shortage and high labor costs.

[0018] 2. Compared with the circular rolling spacer: First, it protects the already covered mulch film. The "marking nails" of the circular rolling spacer are sharper and can easily tear the mulch film during operation. Second, it is not affected by the uneven height of the ridge surface. Third, the marking is very clear. The marking nails of the circular rolling spacer are small, and the markings made during rolling are not very clear. However, the opening diameter of the hole cup of this portable spacer is 3 cm, and the markings are very clear after operation.

[0019] 3. Wide range of uses: In addition to tobacco transplanting, it can also be used for spacing when transplanting crops such as taro, chili peppers, and corn.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0026] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0027] like Figures 1-4 As shown, the portable distance measuring device includes a horizontal support 1, on which two acupoint cups 2 are fitted. One acupoint cup is fixed to one end of the horizontal support, and the other acupoint cup is slidably connected to the horizontal support and positioned by a radially extending bolt 3. The tops of the acupoint cups are coaxially fitted onto the horizontal support via sleeves 4. A through-tube 5 is fixed to the top of the sleeve of the acupoint cup fixed to the end of the horizontal support. An L-shaped distance measuring rod 6 passes through the through-tube. The horizontal end of the distance measuring rod passes into the through-tube and is slidably connected to it and positioned by a radially extending bolt. The vertical end extends vertically downward and is level with the bottom of the acupoint cup. The L-shaped distance measuring rod has two advantages: first, the distance can be adjusted to match the adjustable distance of the acupoint cup, allowing for flexible operation; the distance between acupoints is 45-50 cm. Second, during distance-based acupoint application, it makes a small hole mark on the film covering the planting bed with each acupoint application action, facilitating accurate operation, saving time, and improving efficiency.

[0028] In this embodiment of the utility model, a vertically extending vertical support 7 is fixedly provided in the middle of the horizontal support, and a horizontally extending grip 8 is fixedly provided at the top of the vertical support. Both ends of the grip are covered with rubber sleeves 9.

[0029] In this embodiment of the utility model, the hole-opening cup consists of a top sleeve, a middle cup body 10, and a bottom cone body 11. The cup body is cylindrical, and the cone body is conical with its tip pointing downwards for making holes. The cup body's size (depth, width, and height) is designed according to the dimensions of a "duckbill transplanter," with a height of 18.6 cm and a diameter of 8 cm. Secondly, because its size, height, depth, and width are all designed to meet the needs of transplanting and creating holes for moist seedling tobacco plants, after drilling holes at fixed intervals, it is suitable for the "deep planting technique of applying nutrient soil to small and strong seedlings" required by the tobacco industry for secondary hole-opening and delivery of nutrient soil into the holes. Thirdly, it facilitates deep planting of tobacco seedlings during transplanting, achieving the effect of frost protection for tobacco plants in the early stage of field planting.

[0030] In this embodiment of the utility model, a limiting slide rail 12 is fixedly provided on the outer side of the horizontal support along its length direction, and a slide groove 13 is provided on the inner wall of the sleeve of the opening cup that is slidably connected to the horizontal support, which slides and cooperates with the slide rail.

[0031] In this embodiment of the utility model, the sleeve side and the top of the through pipe are provided with through holes 14 for bolts to be inserted, and nuts 15 are fixed on the sleeve and through pipe outside the through holes to facilitate bolt connection.

[0032] In this embodiment of the utility model, a guide tube 16, which is at the same level as the guide tube and allows the spacer rod to pass through, is fixed at the top of a horizontal support near the guide tube. The guide tube and the guide tube are both tubular and coaxially arranged.

[0033] In this embodiment of the utility model, a triangular reinforcing plate 17 is fixedly connected between the vertical frame and the horizontal support.

[0034] In this embodiment of the utility model, the top of the sleeve of the cup that is slidably connected to the horizontal support is provided with a clearance groove 18 for the clearance reinforcement plate.

[0035] In this embodiment of the utility model, the bottom of the vertical section of the spacer rod is a pointed tip.

[0036] In this embodiment of the utility model, a limiting slide rail is fixedly provided on the horizontal section of the spacer rod along its length direction, and a sliding groove is provided on the inner wall of the through pipe to slide in cooperation with the slide rail.

[0037] In this embodiment of the utility model, the horizontal support and the horizontal section of the spacer rod are both engraved with scale lines 19 along the length direction.

[0038] The working principle of this utility model embodiment is as follows: First, the required acupuncture spacing is set by loosening the bolt and sliding the sleeve and through pipe. The distance between the two acupuncture cups is precisely determined by the scale lines to be consistent with the distance between the fixed acupuncture cup and the vertical section of the spacer rod. Then, acupuncture can begin at equal intervals. After each acupuncture, the acupuncture cup positioned by the bolt will skip the acupuncture position of the fixed acupuncture cup and move directly to the pre-acupuncture position formed by the spacer rod. The efficiency will be greatly improved. Moreover, the cooperation design of the limiting slide rail and the slide groove can effectively prevent the acupuncture cup or the spacer rod from tilting during sliding, ensuring that it always remains horizontal with the fixed acupuncture cup. This makes it convenient for the operator to be accurate, saves time, and improves work efficiency.

[0039] This utility model is not limited to the preferred embodiment described above. Anyone can derive other forms of portable rangefinders based on the teachings of this utility model. All equivalent variations and modifications made within the scope of the claims of this utility model should be considered within the scope of this utility model.
