[0002] Planters are used in agricultural planting. During the planting process, there are generally requirements for the spacing between the plants to be planted. Traditional planters can only open holes in the soil and remove them. The planting hole positions can generally only be determined by manual visual inspection, so there are large errors.

[0003] In response to the above problems, the applicant applied for a distance planting device with patent number CN202321914717.8 on July 19, 2023, including a planting tube, a door-shaped frame is provided at the upper end of the planting tube, a vertical pole is provided at the top of the door-shaped frame, a handle is provided at the top of the vertical pole, a lower joint is provided at the top of the door-shaped frame, a joint thread is provided in the lower joint, a side groove is provided between the inner and outer walls of the lower joint and penetrates to the upper end surface, and the lower end of the vertical pole is screwed and docked with the joint thread; it also includes a distance rod, one end of the distance rod is hinged in the lower joint, the distance rod is parallel to the vertical pole and hidden in the vertical pole, when the distance rod is rotated 90 degrees along the hinge point, it enters the side groove and fixes it when the lower end of the vertical pole is screwed and docked with the joint thread, and the end of the distance rod facing away from the hinge point is provided with a telescopic rod that can be telescopic relative to the distance rod; it has the advantages of convenient storage and can be planted at a fixed distance as needed.

[0004] However, after several months of actual use by the applicant, it was found that the horizontal height of the distance rod and the telescopic rod was close to the top of the planting tube when used at a fixed distance, which made it easy to be interfered by other crops or supports above the ground when moving in some specific occasions, resulting in scratches and collisions between the two. This situation was not foreseen in the environment of a flat ground at the beginning of the design, so it is urgent to improve its structure. Utility Model Content

[0005] Based on the above problems, the utility model aims to provide a projection-type fixed-distance planter that is easy to store and can be planted at fixed distances according to needs, while effectively avoiding crops or supports above the ground and facilitating their movement.

[0006] In view of the above problems, the following technical solutions are provided: a projection type distance planting device, comprising a planting tube, a door-shaped frame is provided at the upper end of the planting tube, a lower upright rod is provided at the top of the door-shaped frame, and an upper upright rod is provided, a handle is provided at the upper end of the upper upright rod, a lower joint is provided at the top of the lower upright rod, a joint thread is provided in the lower joint, a side groove is provided between the inner and outer walls of the lower joint and penetrates to the upper end surface, and the lower end of the upper upright rod is screwed and connected with the joint thread; and a distance rod is also provided, one end of the distance rod is hinged in the lower joint, and the distance rod is connected to the upper upright rod. The vertical poles are parallel to and hidden in the upper vertical pole. When the distance rod rotates 90 degrees along the hinge point, it enters the side groove and fixes it when the lower end of the upper vertical pole is screwed and connected with the joint thread. The end of the distance rod facing away from the hinge point is provided with a telescopic rod that can be telescoped relative to the distance rod. A laser pen is hinged at the end of the telescopic rod. The hinge axis between the telescopic rod and the laser pen is parallel to the hinge axis between the distance rod and the lower joint. When the distance rod rotates 90 degrees along the hinge point, the laser pen rotates 90 degrees relative to the telescopic rod and its light outlet is facing the lower end of the planting tube.

[0007] In the above structure, during daily use, the distance rod is hidden by being folded and inserted into the upper pole; when a distance reference is needed, the upper pole is removed and the distance rod is rotated 90 degrees along the hinge point, and then the upper pole is reinstalled so that the lower end of the upper pole is screwed and connected with the joint thread and at the same time, it is fixed against the distance rod. At this time, the distance rod is 90 degrees perpendicular to the upper pole, and the telescopic rod is adjusted according to the distance length to determine the interval distance between adjacent planting holes. When the distance rod is unfolded, the distance rod and the telescopic rod are parallel to the ground. A laser pen is then set. By rotating the laser pen so that its end is vertically facing the ground, it helps to improve the positioning accuracy. Positioning is performed by the light spot emitted by the laser pen. Since the height of the distance rod is upward, it will not scratch the crops or brackets on the ground when moving.

[0008] The utility model is further configured that the lower upright pole comprises a plurality of lower pole sections, and adjacent lower pole sections are butted against each other by screw thread engagement to increase or decrease the total length of the lower upright pole.

[0009] The utility model is further configured that the upper upright pole comprises a plurality of upper pole sections, and adjacent upper pole sections are butt-jointed by screw threads to increase or decrease the total length of the upper upright pole.

[0010] In the above structure, it is convenient for the user to adjust the length to achieve a suitable height for use.

[0011] The utility model is further configured that a replaceable pen cap is provided at the front end of the laser pen, and a transmission type phase grating is provided in the pen cap.

[0012] In the above structure, the pen cap can be replaced as needed to provide light spot images of different shapes.

[0013] The utility model is further configured such that the transmission type phase grating projection pattern is concentric circles.

[0014] In the above structure, the light emitted by the traditional laser pen is a point-shaped spot, which is easily blocked by the undulating soil and affects observation. The concentric circle spot pattern can facilitate observation and effective positioning; but after setting the transmission phase grating, the brightness of the spot will be attenuated, which is not conducive to working in the open air or strong light environment, so it can be replaced back to a point-shaped spot as needed.

[0015] The utility model is further configured that the telescopic rod is a multi-section rod, which is arranged in a concentric array with each other, and the laser pen is connected to the telescopic rod closest to the center position.

[0016] In the above structure, the length of the spacer in the retracted state can be effectively shortened, and the hinge point of the spacer can be placed as high as possible to raise the horizontal height of the spacer when it is unfolded, thereby reducing the impact on crops or brackets during movement.

[0017] The utility model is further configured that the handle is T-shaped, and the lower end of the handle is threadedly screwed and connected with the upper end of the upper upright rod.

[0018] In the above structure, when the distance rod is unfolded to 90 degrees and parallel to the ground, the axis of the distance rod is parallel to the axis between the two ends of the handle, which is convenient for the operator to control.

[0019] The utility model is further configured such that the door-type frame includes two support columns arranged 180 degrees apart in the circumferential direction of the planting tube, the lower ends of the support columns are connected to the outer wall of the planting tube, the upper ends of the two support columns are connected by a cross beam, and a V-shaped cutting edge is provided on one side of the cross beam facing the planting tube.

[0020] In the above structure, when the planting tube is planted, soil will be brought out from the inside. When the next planting hole is opened, the soil remaining in the planting tube of the previous planting hole will be discharged upward. The V-shaped blade will split the soil in half when the soil is discharged, which helps to discharge the soil while reducing the resistance of opening the hole.

[0021] The utility model is further configured that the lower end surface of the planting tube is provided with a soil breaking cutting edge.

[0022] In the above structure, the soil-breaking cutting edge can reduce the insertion resistance when the planting tube is inserted into the soil.

[0023] The beneficial effects of the utility model are as follows: during daily use, the distance rod is hidden by being folded and inserted into the upper upright pole; when a distance reference is needed, the upper upright pole is removed and then the distance rod is rotated 90 degrees along the hinge point, and then the upper upright pole is reinstalled so that the lower end of the upper upright pole is screwed and connected with the joint thread and at the same time abuts against the distance rod to fix the distance rod. At this time, the distance rod is 90 degrees vertical to the upper upright pole, and then the telescopic amount of the telescopic rod is adjusted according to the distance length to determine the interval distance between adjacent planting holes. When the distance rod is unfolded, the distance rod and the telescopic rod are both parallel to the ground, and then a laser pen is set. By rotating the laser pen so that its end is vertically facing the ground, it helps to improve the positioning accuracy, and positioning is performed by the light spot emitted by the laser pen. Since the height of the distance rod is upward, it will not scratch the crops or brackets on the ground when moving. BRIEF DESCRIPTION OF THE DRAWINGS

And hidden in the upper upright 13, the distance rod 15 enters the side groove 1212 when it rotates 90 degrees along the hinge point and fixes it when the lower end of the upper upright 13 is screwed and docked with the joint thread 1211, and the distance rod 15 is provided with a telescopic rod 151 that can be telescopic relative to the distance rod 15 at one end facing away from the hinge point, and a laser pen 16 is hinged at the end of the telescopic rod 151, and the hinge axis between the telescopic rod 151 and the laser pen 16 is parallel to the hinge axis between the distance rod 15 and the lower joint 121, and when the distance rod 15 rotates 90 degrees along the hinge point, the laser pen 16 rotates 90 degrees relative to the telescopic rod 151 and its light outlet faces the lower end of the planting tube 10.

[0038] In the above structure, during daily use, the distance rod 15 is hidden by being folded and inserted into the upper pole 13; when a distance reference is needed, the upper pole 13 is removed and the distance rod 15 is rotated 90 degrees along the hinge point, and then the upper pole 13 is reinstalled so that the lower end of the upper pole 13 is screwed and connected with the joint thread 1211 and the distance rod 15 is abutted to fix the distance rod 15. At this time, the distance rod 15 is 90 degrees perpendicular to the upper pole 13, and then the telescopic amount of the telescopic rod 151 is adjusted according to the distance length to determine the interval distance between adjacent planting holes. When the distance rod 15 is unfolded, the distance rod 15 and the telescopic rod 151 are both parallel to the ground, and then a laser pen 16 is set. By rotating the laser pen 16 so that its end is vertically facing the ground, it helps to improve the positioning accuracy. Positioning is performed by the light spot emitted by the laser pen 16. Since the height of the distance rod 15 is processed upward, it will not scratch the crops or brackets on the ground when moving.

[0039] In this embodiment, the lower upright pole 12 includes a plurality of lower pole shafts 122 , and adjacent lower pole shafts 122 are connected to each other by screw threads to increase or decrease the total length of the lower upright pole 12 .

[0040] In this embodiment, the upper upright pole 13 includes a plurality of upper pole shafts 131 (a single section is shown in the figure), and adjacent upper pole shafts 131 are connected to each other by screw threading to increase or decrease the total length of the upper upright pole 13 .

[0041] In the above structure, it is convenient for the user to adjust the length to achieve a suitable height for use.

[0042] In this embodiment, a replaceable cap 161 is disposed at the front end of the laser pen 16 , and a transmission phase grating (existing technology, not shown in the figure) is disposed inside the cap 161 .

[0043] In the above structure, the pen cap 161 can be replaced as needed to provide light spot images of different shapes.

[0044] In this embodiment, the projection pattern of the transmission phase grating (existing technology, not shown in the figure) is concentric circles (existing technology, not shown in the figure).

[0045] In the above structure, the light emitted by the traditional laser pen 16 is a point-shaped spot, which is easily blocked by the undulating soil and affects observation. The concentric circle spot pattern can facilitate observation and effective positioning; but after setting the transmission phase grating (existing technology, not shown in the figure), the brightness of the spot will be attenuated, which is not conducive to working in the open air or strong light environment, so it can be replaced back to a point-shaped spot as needed.

[0046] In this embodiment, the telescopic rod 151 is a multi-section rod, which is arranged in a concentric array with each other (in the prior art, it is a single section in the figure), and the laser pen 16 is connected to the telescopic rod 151 closest to the center.

[0047] In the above structure, the length of the distance rod 15 in the retracted state can be effectively shortened, and the hinge point of the distance rod 15 can be placed as high as possible to raise the horizontal height of the distance rod 15 when it is unfolded, thereby reducing the impact on crops or brackets during movement.

[0051] In the above structure, when the planting tube 10 is planted, soil will be brought out from the inside. When the next planting hole is drilled, the soil remaining in the planting tube 10 of the previous planting hole will be discharged upward. The V-shaped cutting edge 1121 will split the soil in half when the soil is discharged, which helps to discharge the soil while reducing the resistance of the hole.

[0052] In this embodiment, a soil breaking cutting edge 101 is provided on the lower end surface of the planting tube 10 .

[0053] In the above structure, the soil breaking edge 101 can reduce the insertion resistance when the planting tube 10 is inserted into the soil.

[0054] The beneficial effects of the utility model are as follows: in daily use, the distance rod 15 is hidden by being folded and inserted into the upper upright rod 13; when a distance reference is needed, the upper upright rod 13 is removed and the distance rod 15 is rotated 90 degrees along the hinge point, and then the upper upright rod 13 is reinstalled, so that the lower end of the upper upright rod 13 is screwed and connected with the joint thread 1211 and at the same time, it is abutted against the distance rod 15 to fix the distance rod 15. At this time, the distance rod 15 is 90 degrees vertical to the upper upright rod 13, and then the telescopic amount of the telescopic rod 151 is adjusted according to the distance length to determine the interval distance between adjacent planting holes. When the distance rod 15 is unfolded, the distance rod 15 and the telescopic rod 151 are both parallel to the ground, and then a laser pen 16 is set. By rotating the laser pen 16 so that its end is vertically facing the ground, it helps to improve the positioning accuracy, and positioning is performed by the light spot emitted by the laser pen 16. Since the height of the distance rod 15 is processed upward, it will not scratch the crops or brackets on the ground when moving.
