Description

Technical Field

[0001] This utility model relates to the field of agricultural seeding equipment technology, specifically to a precision seed-dispensing pen with automatic counting function and rapid stepless diameter adjustment function. Background Technology

[0002] In agricultural research, breeding experiments, and precision farming, it is often necessary to sow a large number of small seeds individually. Existing seed-spotting tools, such as the seed-spotting pen disclosed in patent CN222888224U, while solving the problems of single-seed picking and avoiding seed damage, still have significant shortcomings: First, they cannot automatically count seeds. In experiments requiring precise counting of the number of seeds sown, the operator must additionally record or memorize the number of presses, which can easily lead to counting errors or forgetting, affecting the accuracy of research data. Second, the orifice adjustment method is cumbersome, requiring the replacement of different seed storage rods and outlet membrane components, which is inconvenient to operate and prone to losing small parts during experiments. It cannot quickly respond to the need for frequent changes in seed varieties during experiments, affecting work efficiency. Third, seeds are prone to clogging in the channel, affecting sowing efficiency. Therefore, there is an urgent need for a highly efficient seed-spotting tool that integrates automatic counting, rapid orifice adjustment, and anti-clogging features. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a seed-spreading pen that is easy to operate, accurate in sowing, countable, and can be quickly and steplessly adjusted in diameter.

[0004] To achieve the above technical objectives, the following technical solution is adopted: An adjustable diameter counting seed pen includes a pen body, a pressing head, a seed chamber, a seed dispensing rod, and a return spring; it also includes an integrated quick diameter adjustment module and a counting module; The pen body is a hollow tubular structure with a seed chamber at its upper part, and the pressing head is located on the top of the seed chamber; the lower seed rod is a hollow tubular structure that is slidably housed in the inner cavity of the pen body, and its top is detachably connected to the bottom of the seed chamber; the return spring is sleeved on the outside of the lower seed rod to provide an elastic force for the lower seed rod to return to its original position. The integrated quick diameter adjustment module is located at the bottom of the pen body and includes an adjustment ring, an adjustable orifice seed outlet head, and a flexible inner liner tube. The adjustment ring is threaded to the pen body. The flexible inner liner tube is sleeved on the outside of the seeding rod, with its upper end fixedly connected to the inner wall of the pen body and its lower end mechanically linked to the adjustable orifice seed outlet head. The counting module is mounted on the pen body and includes a triggering mechanism associated with the movement of the seeding rod.

[0005] Furthermore, the inner cavity at the bottom of the pen body is a conical cavity that is larger at the top and smaller at the bottom; the seed outlet head with adjustable aperture is composed of at least two relatively sliding conical mold pieces, which are housed within the conical cavity.

[0006] Furthermore, the inner wall of the adjusting ring forms an inner conical surface, and the outer conical surface of the mold piece matches the inner conical surface of the adjusting ring; by rotating the adjusting ring to generate axial displacement, its inner conical surface squeezes the outer conical surface of the mold piece, driving the mold piece to gather or disperse along the inner wall of the conical cavity of the pen body.

[0007] Furthermore, the lower end of the flexible inner liner tube is fixedly connected to the top of the mold flap via a connecting ring; when the mold flap is brought together, the lower end of the flexible inner liner tube is compressed and contracted; when the mold flap is dispersed, the lower end of the flexible inner liner tube expands and resets under its own elasticity.

[0008] Furthermore, the circumferential sidewall of the adjusting ring is provided with a scale; a seed size reference scale that is used in conjunction with the scale is fixed on the main body of the pen.

[0009] Furthermore, the counting module is a magnetoelectric induction counting module, including a magnet fixed on the lowering rod, a magnetic control switch fixed on the inner wall of the pen body, and an electronic counter electrically connected to the magnetic control switch, wherein the electronic counter is located on the outer side of the pen body.

[0010] Furthermore, the magnetic switch is a reed switch, and its installation position is configured such that when the planting rod is reset upward to the initial position, the magnet aligns with it and triggers the electronic counter to count.

[0011] Furthermore, an anti-rotation structure is provided between the seeding rod and the pen body, which consists of a keyway on the outer wall of the seeding rod and a key on the inner wall of the pen body.

[0012] Furthermore, the seed chamber and the seed lowering rod are detachably connected by threads.

[0013] Furthermore, the side wall of the pen body is provided with an observation window, the position of which corresponds to the upper middle part of the internal channel of the lower seed rod.

[0014] This invention provides an adjustable diameter counting seed-dispensing pen. Compared with the prior art, the advantages of this invention are: 1. One-twist diameter adjustment, quick adaptation: The seeding diameter can be steplessly changed by rotating the diameter adjustment ring without replacing any parts, which greatly improves work efficiency.

[0015] 2. Automatic counting and accurate data: Automatic counting after each effective sowing eliminates errors and omissions caused by manual counting, making it especially suitable for scientific research experiments.

[0016] 3. Smooth sowing, not easy to clog: The inner wall of the seed channel formed by the flexible inner liner tube and the mold is smooth and seamless. Combined with the piston-like pushing action of the seed rod, sowing is smooth and reliable.

[0017] 4. Stable structure and comfortable operation: The anti-rotation structure ensures the stability of counting and seeding; the ergonomic design makes operation easy and effortless. Attached Figure Description

Detailed Implementation

[0026] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. The described embodiments are merely some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] like Figure 1-2As shown, the present invention discloses an adjustable diameter counting seed pen, which mainly consists of a pen body 1, a pressing head 2, a seed chamber 3, a seed feeding rod 4, a return spring 5, an integrated quick diameter adjustment module 6, and a counting module 7.

[0028] The pen body 1 is a hollow tube with a seed chamber 3 at its upper end and a pressing head 2 on top of the seed chamber 3. The lower seed rod 4 is a hollow tube with its top detachably connected to the bottom of the seed chamber 3 via threads. The lower seed rod 4 is slidably housed within the inner cavity of the pen body 1. A return spring 5 is fitted around the lower seed rod 4 to provide it with a return force. An observation window 11 is provided on the side wall of the pen body 1 to observe the remaining amount of seeds inside the lower seed rod 4.

[0029] like Figure 3-4 As shown, the integrated quick-adjustment module 6 is located at the bottom of the pen body 1. The inner cavity at the bottom of the pen body 1 is a conical cavity that is larger at the top and smaller at the bottom, containing three conical mold segments 62. The outer side of the mold segments 62 is a bevel. The adjustment ring 61 is screwed onto the lower end of the pen body 1 by threads, and its inner wall is an inner conical surface that matches the outer bevel of the mold segments 62. The flexible inner liner tube 63 is made of food-grade silicone or flexible rubber, and is fitted over the seeding rod 4. Its upper end is fixed to the inner wall of the pen body 1, and its lower end is fixed to the top of the mold segments 62 by a connecting ring 64. Rotating the adjustment ring 61 causes the mold segments 62 to be squeezed by the conical surface, making them gather or disperse along the conical cavity of the pen body 1, and simultaneously pulling the lower end of the flexible inner liner tube 63 to deform, thereby achieving stepless adjustment of the seed outlet diameter. The side wall of the adjustment ring 61 is provided with a scale 611, and a corresponding seed size reference scale 13 is attached to the pen body 1 for easy and quick setting.

[0030] like Figure 5 As shown, the counting module 7 is a magnetoelectric induction type. A magnet 73 is fixed to the outer wall of the seeding rod 4, and a reed switch 72 is fixed to the inner wall of the pen body 1 at a corresponding height. When the seeding rod 4 returns to its top position, the magnet 73 triggers the reed switch 72, causing the electronic counter 71 to count once. The electronic counter 71 is fixed to the outer side of the pen body 1. Figure 6 As shown, the pen body 1 and the lower seed rod 4 are connected by an anti-rotation structure through the key 12 and keyway 41 to ensure stable movement and accurate counting.

[0031] The working process of this utility model is as follows: First, add seeds into the seed chamber 3. Rotate the adjusting ring 61 to the desired scale. Its internal conical surface drives the mold petals 62 to converge or disperse, simultaneously deforming the lower end of the flexible inner liner tube 63 to set the seed outlet diameter. Then, hold the pen body 1 and press the pressing head 2. The seed-discharging rod 4, fixedly connected to the pressing head 2, then descends, pushing the bottommost seed out of the adjusted seed outlet. Upon release, the return spring 5 pushes the seed-discharging rod 4 upwards. When it reaches its highest point, the magnet 73 on the seed-discharging rod triggers the reed switch 72 on the inner wall of the pen body, automatically incrementing the number on the electronic counter 71. Simultaneously, as the seed-discharging rod 4 returns to its upward position, the seeds automatically fall under gravity, filling the bottom empty space and preparing for the next sowing.
