Description

Technical Field

[0001] This utility model relates to the field of agricultural production technology, and in particular to an adjustable plant spacing positioning device. Background Technology

[0002] In modern agricultural production, crop planting density is one of the important factors affecting crop yield and quality. Especially in the planting of crops such as corn and sorghum, appropriate plant spacing can significantly improve the photosynthetic efficiency of crops, thereby increasing yield per unit area. However, when conducting field density-related experiments, traditional manual measurement of plant spacing has many inconveniences and limitations.

[0003] Currently, while large-scale seeding machinery can adjust seeding density, it is primarily suitable for large-scale commercial planting. In agricultural scientific research, especially in field plot trials, the small size of the experimental plots makes it impossible or unsuitable for large machinery to enter. Therefore, researchers typically use manual measurement to determine plant spacing. Manual measurement is not only labor-intensive but also difficult to maintain, directly impacting the accuracy and repeatability of experimental data.

[0004] In traditional manual measurement of plant spacing, researchers typically use simple methods such as ropes or step estimation to control the required spacing for different needs. However, this method suffers from problems such as low accuracy, low efficiency, and poor adjustability.

[0005] Therefore, designing a sowing positioning device that can precisely control plant spacing and adapt to different density requirements has become a pressing technical problem in agricultural research. Existing tools cannot meet the needs of efficient, accurate, and convenient plant spacing positioning in field trials. Utility Model Content

[0013] In one possible implementation, the rotary feeding mechanism is also provided with a feeding hole.

[0014] In one possible implementation, the locking mechanism includes a lock body with a slot for connecting to an auxiliary rope, and a channel communicating with the slot on one side of the lock body.

[0015] In one possible implementation, a lock hole is provided at the top of the channel, a slider is slidably connected to the outside of the lock hole, a locking rod is connected to the slider, and the locking rod is built into the lock hole.

Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In addition, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this utility model can be understood according to the specific circumstances.

[0032] This utility model provides an adjustable plant spacing positioning device, such as Figures 1 to 4 As shown. The device includes multiple fixed rods 1, with auxiliary ropes 2 connecting the multiple fixed rods 1, and a ranging and positioning component slidably connected to the auxiliary ropes 2.

[0033] Specifically, the number of fixing rods 1 is determined according to the planting requirements and plant spacing requirements of the experimental field. For example, fixing rods 1 can be set in a straight line, a Y-shape, etc. The fixing rods 1 can be made of regular or smooth, reflective, opaque objects, such as metal ground stakes, to provide feedback on the ranging signal of the ranging and positioning components. The auxiliary rope 2 is used to support the other components of this device so that they can function normally, and its horizontal direction should be parallel to the ground.

[0034] For example, the ranging and positioning component includes a locking mechanism 4 connected to the auxiliary rope 2. One end of the locking mechanism 4 is detachably connected to the ranging mechanism 3, and the other end of the locking mechanism 4 is hinged to a storage bin 6. The other end of the storage bin 6 is connected to a rotating feeding mechanism 8.

[0035] Specifically, the ranging mechanism 3 used in this device is an existing technology, such as HILTIPD-S, PD-E and Newcon LRM3500M-35BT, which can meet the usage requirements.

[0036] For example, a grid 7 is detachably provided inside the storage bin 6. One end of the grid 7 is hinged to the locking mechanism 4, and a baffle 71 is fixedly provided at the other end of the grid 7. The grid 7 divides the storage bin 6 into multiple independent compartments.

[0037] Specifically, the number of independent compartments that the grille 7 divides into in the storage bin 6 is determined as needed. Furthermore, baffles 71 are placed at the bottom of the storage bin 6, thereby securing the grille 7 inside the storage bin 6.

[0038] Specifically, a chute is provided on the inner side of the storage bin 6, and the outer end of the grid 7 slides on the chute.

[0039] Specifically, a retaining ring is provided at the bottom of the storage bin 6, and a baffle plate 71 is placed above the retaining ring.

[0040] For example, a rotating shaft 72 is fixedly provided on the side of the baffle plate 71 away from the storage bin 6, and the baffle plate 71 has multiple through discharge ports 73, which correspond to multiple independent bins.

[0041] Specifically, the grid 7 rotates within the storage silo 6 via the rotating shaft 72, or the storage silo 6 and the grid 7 rotate together via the rotating shaft 72. The discharge port 73 corresponds one-to-one with the independent compartments, achieving the purpose of individual material discharge from each independent compartment within the storage silo 6.

[0042] For example, the rotating shaft 72 includes a bushing 721 connected to the baffle plate 71, and the bushing 721 is rotatably connected to a screw 722.

[0043] Specifically, the grille 7, the baffle plate 71, and the bushing 721 can be integrated into one unit and then rotate on the screw 722.

[0044] For example, the rotary feeding mechanism 8 includes a shaft hole 81 rotatably connected to the bushing 721. The side wall of the rotary feeding mechanism 8 is provided with a limiting hole 82 communicating with the shaft hole 81. A limiting rod 83 is internally threaded into the limiting hole 82. A limiting piece 84 is provided on the side of the limiting rod 83 near the shaft hole 81.

[0045] Specifically, a limiting hole 82 is provided on the side wall of the rotary feeding mechanism 8, which connects the outside of the rotary feeding mechanism 8 and the shaft hole 81. A limiting rod 83 is threaded into the limiting hole 82, and the limiting rod 83 controls the limiting piece 84 to move closer to or away from the shaft hole 81.

[0046] For example, the bushing 721 is rotatably connected within the shaft hole 81, and one end of the screw 722 is embedded in the bottom of the shaft hole 81.

[0047] Specifically, the bottom of the shaft hole 81 is provided with a groove for locking the screw 722.

[0048] Specifically, the storage bin 6 and the grid 7 rotate in the shaft hole 81 via the bushing 721, while the screw 722 is locked in the shaft hole 81. That is, the storage bin 6 and the grid 7 are rotatably connected to the rotating feeding mechanism 8 via the screw 722.

[0049] For example, the rotary feeding mechanism 8 is also provided with a feeding hole 85.

[0050] Specifically, when the discharge hole 85 is opposite to the outlet 73, the material in the storage bin 6 can flow out along the discharge hole 85.

[0051] Specifically, the vertical center of the bottom end of the feeding hole 85 is aligned with the vertical center of the ranging mechanism 3.

[0052] For example, the locking mechanism 4 includes a lock body 41, which has a slot for connecting to the auxiliary rope 2, and a channel communicating with the slot is provided on one side of the lock body 41.

[0053] Specifically, the locking mechanism 4 slides on the auxiliary rope 2 through the slot, and the channel communicating with the slot is used for the auxiliary rope 2 to enter the slot.

[0054] For example, a lock hole 42 is provided at the top of the channel, a slider 43 is slidably connected to the outside of the lock hole 42, a locking rod 44 is connected to the slider 43, and the locking rod 44 is built into the lock hole 42.

[0055] Specifically, the slider 43 drives the locking rod 44 to slide up and down inside the lock hole 42, opening or closing the passage.

[0056] Specifically, a slide bar is provided at the bottom of the lock body 41, allowing the storage bin 6 and the grid 7 to be close to or away from the ground. Furthermore, the slide bar can be single or multiple.

[0057] For example, the device also includes a hopper cover 5, which is slidably connected to the locking mechanism 4 and corresponds to the top of the storage hopper 6.

[0058] Specifically, the cover 5 can slide to move closer to or further away from the opening of the storage bin 6.

[0059] Example:

[0060] To determine the required plant spacing for field trials, when using this device, first insert multiple fixed rods 1 vertically into the soil at both ends of the experimental field, ensuring the fixed rods 1 are perpendicular to the ground. Then, connect both ends of the auxiliary rope 2 to the fixed rods 1. The auxiliary rope 2 should be a certain distance from the ground, or the distance between the auxiliary rope 2 and the ground should be greater than the height of the ranging and positioning components.

[0061] After the auxiliary rope 2 is straightened and parallel to the horizontal ground of the test field, the slider 43 of the sliding locking mechanism 4 pushes the locking rod 44 out of the lock hole 42. At this time, the opening of the locking mechanism 4 allows the auxiliary rope 2 to be inserted into the slot of the lock body 41, and the slider 43 pushes the locking rod 44 into the lock hole 42, so that the locking mechanism 4 slides on the auxiliary rope 2 to adjust its position.

[0062] Next, open the bin cover 5 and slide it onto the locking mechanism 4. At this time, the grid 7 can be selected according to the actual situation of the plant spacing marking. For example, if there are three types of plant spacing marking, a grid 7 with three discharge ports 73 corresponding to the baffle plate 71 can be selected. If there are five types of plant spacing marking, a grid 7 with five discharge ports 73 corresponding to the baffle plate 71 can be selected.

[0063] After selecting the grid 7, place it on the retaining ring at the bottom of the storage bin 6 using the baffle plate 71. Select the appropriate pigment according to the type of plant spacing mark and place it into the independent compartment within the storage bin 6. Before placing the pigment into the storage bin 6, the discharge holes 85 on the rotating feeding mechanism 8 are closed, meaning that the discharge holes 85 and the outlets 73 do not correspond one-to-one.

[0064] After the pigment is added to the storage bin 6 and adjusted, the distance measuring mechanism 3 is opened, and the sliding locking mechanism 4 is engaged. Once the distance measuring mechanism 3 displays the set plant spacing mark, the limiting rod 83 is rotated. The limiting rod 83 rotates within the limiting hole 82, pushing the limiting piece 84 into the shaft hole 81. The rotating shaft 72 connected to the baffle plate 71 rotates within the shaft hole 81, the bushing 721 slides within the shaft hole 81, and the threaded section of the screw 722 rotates within the bushing 721. The bottom of the screw 722 is embedded in the groove of the shaft hole 81.

[0065] Therefore, when the limiting plate 84 is pushed into the shaft hole 81, it tightens after approaching the screw 722. The friction between the limiting plate 84 and the screw 722 fixes the rotating feeding mechanism 8 at the position corresponding to the feeding hole 85 and the discharge port 73. At this time, the pigment in the independent compartment of the corresponding storage bin 6 enters the feeding hole 85 of the rotating feeding mechanism 8 through the discharge port 73. Accordingly, the pigment falls through the feeding hole 85 to the location in the experimental field where plant spacing marking is required, thus completing the marking.

[0066] In practical applications, the pigment for marking plant spacing can be placed in the independent compartment of the storage bin 6 first, and then the ranging and positioning component can be connected to the auxiliary rope 2 through the locking mechanism 4.

[0067] In practical applications, the above embodiments provide one application method for this device, and its specific structure can be found in [reference needed]. Figures 1-4 The locking mechanism 4 and the grille 7 are provided with a movable connecting member. The cover 5 is slidably connected to the locking mechanism 4, which can be the structure in the embodiment, see [reference]. Figure 2 Alternatively, it can be configured as a separate connecting rod.

[0068] The various embodiments in this specification are described in a progressive manner. For the same or similar parts between the various embodiments, please refer to each other. Each embodiment focuses on describing the differences from other embodiments.

[0069] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
