Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, specifically a lime spreader for marking the planting location of mulberry trees. Background Technology

[0002] The transplanting and planting of mulberry trees typically involves first drawing a grid on the transplanting field according to a predetermined fixed spacing between rows and plants. The intersections of the lime lines serve as markers for the planting sites. Later, holes are dug and the saplings are planted based on these markers. This preparatory work, including drawing the grid and spreading lime, requires a significant amount of manpower, lime, and time. To improve efficiency and reduce the time spent marking the planting sites, workers often rely on experience to intermittently sprinkle lime at the designated planting locations, thus increasing the efficiency of marking the mulberry tree planting sites.

[0003] Patent CN221733920U discloses a lime spreader for marking mulberry planting locations, comprising: a walking mechanism; a lime spreader body mounted on the walking mechanism, the lime spreader body including: a shell with a lime inlet at the top and a lime outlet at the bottom; a pair of crushing rollers disposed within the shell; a feeding cylinder, cylindrical in shape and horizontally positioned, fixed to the bottom of the shell, with a first notch at the top and bottom, the upper first notch communicating with the lime outlet; a feeding disc, cylindrical in shape and inserted into the feeding cylinder, with at least one second notch; and a rotating shaft coaxial with the feeding disc, one end of which is fixedly connected to the feeding disc, the other end rotating under power. This device can achieve fast, accurate, lime-saving, labor-saving, and safe lime spreading for marking mulberry planting locations according to a set plant spacing.

[0004] However, the lime spreader in the above-mentioned technology still has the following problems: Although the feeding tray can accurately apply lime at the planting point and reduce lime powder scattering, it is difficult to clearly measure the distance between adjacent points when marking the planting points, which can easily lead to small marking errors. When carrying out large-scale mulberry tree planting operations, these small errors may accumulate, resulting in deviations in the final number of trees planted and the planting area, which is not conducive to the smooth progress of planting management.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1 to 5 A lime spreader for marking the planting location of mulberry trees includes a lime spreader 1. A horizontal adjustment ruler 2 and a vertical adjustment ruler 3 are connected to the upper surface of the lime spreader 1. Both ends of the horizontal adjustment ruler 2 are connected to a horizontal extension ruler 4. The end of the vertical adjustment ruler 3 away from the head of the lime spreader 1 is connected to a vertical extension ruler 5. The vertical adjustment ruler 3 is moved and adjusted along the center line of the lime spreader 1.

[0025] like Figures 1 to 5As shown, the lime spreader for marking mulberry planting locations in this utility model is structurally similar to existing lime spreaders for marking mulberry planting locations, such as the lime spreader for marking mulberry planting locations disclosed in patent publication number CN221733920U. The main improvement of this utility model lies in improving the accuracy of the marking of planting locations, such as... Figures 1 to 5 As shown, the lime spreader for marking mulberry planting positions in this utility model, when in use, allows for the measurement of the distance between the lime spreader 1 and the lateral marking points by installing a horizontal extension ruler 4 at either end of the horizontal adjustment ruler 2, according to planting needs. A longitudinal extension ruler 5 is installed at the end of the vertical adjustment ruler 3 to measure the distance between the lime spreader 1 and the previous planting marking position. Combined with the horizontal adjustment ruler 2, the distance between the upcoming planting position and the previous and lateral marking positions can be directly measured, ensuring that the upcoming planting position is aligned with other planting positions. The spacing of the marked positions meets the planting interval requirements of mulberry trees, avoiding large errors that may occur when marking based on experience, and making the planting position marking more accurate. It should be noted that when installing the horizontal adjustment ruler 2 and the vertical adjustment ruler 3, the measurement position needs to be measured from the lime drop mark position of the lime spreading vehicle 1 to the end of the extension ruler. By using the perpendicular relationship between the horizontal adjustment ruler 2 and the vertical adjustment ruler 3, the lime drop mark and the ends of the two extension rulers form three planting position marking points, which can indicate the required plant spacing distance, thus accurately completing the marking of the planting position.

[0026] like Figures 1 to 5 As shown, a horizontal adjustment groove 201 is formed through the upper surface of the horizontal adjustment ruler 2. A horizontal fixing bolt 6 is connected inside the horizontal adjustment groove 201. The threaded rod of the horizontal fixing bolt 6 passes through the horizontal adjustment groove 201 and is connected to the lime spreading vehicle 1. After connecting the horizontal fixing bolt 6 to the lime spreading vehicle 1 through the horizontal adjustment groove 201, the horizontal adjustment ruler 2 can be adjusted horizontally left and right with the horizontal fixing bolt 6 as the fixed point. This, in conjunction with the horizontal extension ruler 4 installed at the end, allows for adjustment of the overall length of the horizontal ruler according to planting needs, improving the applicability of the horizontal adjustment ruler 2.

[0027] like Figure 1 and Figure 2 As shown, both sides of the horizontal adjustment ruler 2 are connected to limit plates 7, and both limit plates 7 are fixedly connected to the upper surface of the lime spreading vehicle 1. When the horizontal adjustment ruler 2 is adjusted horizontally left and right, the two limit plates 7 keep the horizontal adjustment ruler 2 in a horizontal state, preventing the horizontal adjustment ruler 2 from tilting on the lime spreading vehicle 1.

[0028] like Figure 2As shown, a T-shaped groove 101 is provided on the upper surface of the lime spreading vehicle 1. The T-shaped groove 101 is located between two limiting plates 7. A T-shaped slider 8 is slidably connected in the T-shaped groove 101. A fastening screw hole 801 is provided at the end of the T-shaped slider 8 away from the T-shaped groove 101. The threaded rod of the transverse fixing bolt 6 passes through the transverse adjusting groove 201 and is threadedly connected to the fastening screw hole 801. When adjusting the transverse adjusting ruler 2 to move laterally, the transverse adjusting ruler 2 can be pulled to one side, which will drive the T-shaped slider 8 to move in the T-shaped groove 101. After the adjustment is completed, the transverse fixing bolt 6 is tightened into the fastening screw hole 801 of the T-shaped slider 8, thereby clamping the transverse adjusting ruler 2 onto the lime spreading vehicle 1. With the help of the two limiting plates 7, the transverse adjusting ruler 2 can be firmly fixed onto the lime spreading vehicle 1, ensuring the stability and accuracy of transverse dimension measurement during planting and marking operations.

[0029] like Figures 1 to 5 As shown, both ends of the horizontal adjustment ruler 2 have horizontal mounting holes 202. One end of the horizontal extension ruler 4 is fixedly connected to a horizontal mounting block 41. The horizontal mounting block 41 is slidably connected to the horizontal mounting hole 202 at either end of the horizontal adjustment ruler 2. A bolt passes through the horizontal mounting hole 202 and is threadedly connected to the horizontal mounting block 41. The horizontal extension ruler 4 can be installed in the horizontal mounting hole 202 at either end of the horizontal adjustment ruler 2 through the horizontal mounting block 41, or the horizontal extension ruler 4 can be installed at both ends of the horizontal adjustment ruler 2. This allows for simultaneous measurement of the spacing between three positioning marks in the same row, improving the accuracy of the positioning measurement. After the horizontal mounting block 41 is inserted into the horizontal mounting hole 202, a bolt is used to pass through the pre-drilled hole in the horizontal mounting hole 202 and threadedly fasten it to the horizontal mounting block 41, thus securing the splicing position and ensuring that it will not fall off during use.

[0030] like Figure 4 As shown, the end of the horizontal extension ruler 4 furthest from the horizontal mounting block 41 has a horizontal splicing hole 401 that matches the horizontal mounting block 41. Multiple horizontal extension rulers 4 can be installed sequentially at the other end of the horizontal extension ruler 4 in the same manner, thereby further extending the length of the horizontal measuring ruler and increasing the horizontal measuring range.

[0031] like Figures 1 to 5 As shown, a longitudinal adjusting groove 301 is formed through the upper surface of the longitudinal adjusting ruler 3. A longitudinal fixing bolt 9 is connected inside the longitudinal adjusting groove 301. The threaded rod of the longitudinal fixing bolt 9 passes through the longitudinal adjusting groove 301 and is threadedly connected to the lime spreading vehicle 1. Similar to the structure of the transverse adjusting ruler 2, the longitudinal adjusting ruler 3 can be fixed on the lime spreading vehicle 1 after adjustment by the longitudinal fixing bolt 9.

[0032] like Figures 1 to 5As shown, a T-shaped limiting rod 10 is slidably connected within the longitudinal adjusting chute 301. The thinner end of the T-shaped limiting rod 10 passes through the longitudinal adjusting chute 301 and is fixedly connected to the lime spreading vehicle 1. The T-shaped limiting rod 10 and the longitudinal fixing bolts 9 are spaced apart. The T-shaped limiting rod 10, in conjunction with the spaced longitudinal fixing bolts 9, ensures, through a two-point positioning method, that the longitudinal adjusting ruler 3 is always perpendicular to the transverse adjusting ruler 2 on the lime spreading vehicle 1, thereby stably measuring the spacing of the longitudinal planting positions.

[0033] like Figures 1 to 5 As shown, the longitudinal adjusting ruler 3 has a longitudinal mounting hole 302 at the end furthest from the head of the lime spreading vehicle 1. One end of the longitudinal extension ruler 5 is fixedly connected to a longitudinal mounting block 51, and the other end has a longitudinal splicing hole 501 that matches the longitudinal mounting block 51. The longitudinal mounting block 51 is slidably connected to the longitudinal mounting hole 302, and a bolt passes through the longitudinal mounting hole 302 and is threadedly connected to the longitudinal mounting block 51. The longitudinal extension ruler 5 has the same structure as the transverse extension ruler 4, facilitating the extension of the measurement range at the end of the longitudinal adjusting ruler 3.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
