Technical Field
[0001] This utility model belongs to the technical field of seed weaving machines, and in particular relates to a pneumatic suction composite seed tape weaving machine. Background Technology
[0002] Sowing is a crucial part of agricultural production. In recent years, the global emphasis on the seed industry has been continuously increasing, and breeding technology has made great progress. However, due to the irregular shape and uneven grain size of some crops (such as cottonseed and vegetables), it is difficult to ensure sowing accuracy and stability during precision sowing. Existing sowing methods cannot meet the needs of simultaneously sowing both large and small seeds. Seed tape (also known as seed rope) technology, as a niche precision sowing technology used to improve agricultural sowing accuracy, effectively solves the problem of precision seed sowing by virtue of its advantages in quantitative and positional sowing.
[0003] Common seed band making methods are mainly divided into two types: adhesive fixing and spiral twisting seed wrapping. The adhesive fixing method involves attaching seeds to biodegradable materials (such as paper or non-woven fabric) with adhesive substances such as glue at a set spacing and arrangement. Although this method can achieve precise sowing, it is costly and not conducive to seed growth. The spiral twisting seed wrapping method uses a CNC seed rope weaving machine to wrap and fix the seeds with materials such as paper strips, non-woven fabric strips, and outer wrapping wire. However, in this method, the seeds and strips move rapidly before the outer wrapping wire is wrapped, which can easily lead to uneven spacing between the seeds.
[0004] To improve seed packing efficiency and quality, this solution proposes an automatic seed pack weaving machine that combines feeding, delivery, and weaving, based on the weaving principle of the May Pillar weaving machine. Utility Model Content
[0005] The purpose of this invention is to provide a pneumatic suction composite seed rope weaving machine. This solution uses a pneumatic reciprocating feeding mechanism to perform uniform and equidistant automatic seed feeding operation, and uses multiple strands of biodegradable chemical fiber to interweave with each other to wrap the seeds and form seed ropes, thus eliminating the shortcomings of traditional seed bonding and fixing methods and strip spiral twisting seed wrapping methods.
[0006] To address the aforementioned issues, this solution provides a pneumatically operated, composite seed tape weaving machine.

[0008] A winding assembly, which is mounted on the frame and located behind the vertical base plate, includes at least a seed braiding ring and a winding assembly. The seed braiding ring is located at the center of the multi-strand wire bundle to reduce the radial tension of the wire bundle and thus form a seed wrapping area. The winding assembly is used to wind up the seed rope after it has been braided by the braiding assembly.
[0009] The feeding assembly is mounted on the frame and located in front of the vertical base plate. It includes a seed box and a pneumatic reciprocating feeding mechanism.

[0010] As the preferred embodiment of this application:
[0011] The pneumatic reciprocating feeding mechanism includes a pneumatic seed-picking rod and a reciprocating moving component. A negative pressure pipeline is connected to the pneumatic seed-picking rod, which can create a negative pressure at the seed-picking end of the pneumatic seed-picking rod to adsorb the seeds 9.

[0014] As the preferred embodiment of this application:
[0015] Limit sensors are provided at both ends of the roller, and a fixing ring is provided on the pneumatic seed-taking rod. When the fixing ring moves with the pneumatic seed-taking rod, it can contact the limit sensors to control the opening and closing of the negative pressure pipeline and the start and stop of the drive motor A.
[0016] As a preferred embodiment of this application: the seed box is provided with a seed dispensing tray, which has seed dispensing holes arranged at equal intervals. When the seed dispensing tray rotates, it can carry a certain amount of seeds from the seed box and drop them down.
[0017] As the preferred embodiment of this application:
[0018] The vertical substrate has a through opening with a seed feeding limiting tube extending to the seed braiding ring, and the seed feeding limiting tube is coaxially arranged with the seed braiding ring.
[0019] As the preferred embodiment of this application:
[0020] The rope winding assembly includes a rope-guiding rubber ring, a rope-arranging assembly, and a rope winding reel arranged sequentially from front to back. The rope-guiding rubber ring is coaxially arranged with the seed weaving ring to limit the forward direction of the seed rope. The rope-arranging assembly is used to drive the seed rope to move back and forth to evenly wind the seed rope onto the rope winding reel.
[0021] As the preferred embodiment of this application:
[0022] The braiding assembly is fixed to the vertical base plate on the side near the feeding assembly. The braiding assembly includes a gear assembly and a spindle assembly. The gear assembly includes a drive gear that meshes with each other and multiple sets of pinions. The multiple sets of pinions are arranged in a circular array on the outer periphery of the through opening. The number of spindle assemblies corresponds to the number of pinions, and each spindle assembly includes a yarn carrier and a limiting post. The spindle assembly is fixed to the pinion by the limiting post and rotates with the pinion, thereby driving the yarn carrier to rotate to perform yarn bundle interlacing.
[0023] As the preferred embodiment of this application:
[0024] The vertical base plate has a hollow structure, the gear assembly is installed in the hollow cavity of the vertical base plate, and a motion guide rail is provided on the rear end face of the vertical base plate. The motion guide rail is used to limit and guide the spindle assembly.
[0025] As the preferred embodiment of this application:
[0026] The multiple sets of small gears have four slots on their circumference, and the limiting post head is closely set at the corresponding slot position. When the small gear rotates, it drives the spindle assembly to move to the next small gear.

Detailed Implementation
[0037] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present invention.
[0038] This embodiment provides a pneumatic suction composite seed tape weaving machine. See [link / reference] Figure 1-2 As shown, the braiding machine includes a frame 1, and a braiding assembly, a winding assembly and a feeding assembly disposed on the frame 1.
[0039] The braiding assembly is mounted on a vertical base plate 2 located near the center of the frame 1. This braiding assembly is used to interweave multiple strands of wire 215 to form a spiral braided rope. A through opening is provided in the central region of the braiding assembly on the vertical base plate 2. In this embodiment, the braiding assembly preferably adopts the braiding principle of a conventional five-column horizontal braiding machine. Furthermore, the wire 215 used in this embodiment is biodegradable synthetic fiber. The winding assembly is mounted on the frame 1 via a bracket B309 and is located behind the vertical base plate 2. In this embodiment, "behind" here and "front" below are both relative to the orientation of the seed 109. Figure 1 As shown, the rope winding assembly includes at least a seed braiding ring 214 and a rope winding assembly. The seed braiding ring 214 is located at the center of the multi-strand wire bundle 215, serving both as a seed 109 delivery limit point and reducing the radial tension of the wire bundle 215 by increasing the braiding angle, thereby forming a seed 109 wrapping area. After the seed 109 is delivered to this seed 109 wrapping area, it can be wrapped by the interwoven wire bundle 215 and then woven into the braided rope. In this embodiment, a conical gathering rubber ring 301 is preferably sleeved on the outside of the seed braiding ring 214. The gathering rubber ring 301 is supported by a vertical rod and is used to guide the spiral braided rope with the seed 109 wrapped at the rear end of the seed braiding ring 214. The rope winding assembly is used to wind up the spiral braided rope with the seed 109 after the braided assembly is interwoven, such as... Figure 6 As shown, the spiral braided rope can also be called seed rope 401; the feeding assembly is mounted on the frame 1 via bracket A101 and is located in front of the vertical base plate 2. It includes a seed box 110 and a pneumatic reciprocating feeding mechanism. The seed box 110 stores seeds 109, which are used to quantitatively and evenly sow the seeds, ensuring that the seeds 109 are evenly distributed on the seed rope 401, thereby improving the sowing accuracy. The pneumatic reciprocating feeding mechanism uses an adsorption method to pick up the falling seeds 109 from the seed box 110 and can transport the seeds 109 through the through opening to the seed braiding ring 214 to wrap the seeds 109.
[0040] In summary, compared to conventional weaving machines, this weaving machine uses multi-strand chemical fiber filaments interwoven to wrap the seeds 109. Compared to paper tape wrapping, it ensures both air permeability and water permeability, which is beneficial for better seed germination. Furthermore, this weaving machine uses a pneumatic reciprocating feeding mechanism for uniform and quantitative seed feeding, preventing seeds 109 from shifting or falling off during transport and ensuring that multiple seeds 109 are evenly distributed. It is also suitable for seeds 109 of different sizes, making it widely applicable. In addition, this weaving machine, consisting of a feeding assembly, a weaving assembly, and a rope winding assembly, forms a fully automatic seed 109 weaving structure, reducing human error. Therefore, the weaving machine provided by this solution not only improves seed wrapping efficiency and quality but also has a wider range of applications, making it particularly suitable for engineering and technical personnel in new agricultural processing enterprises and agricultural research institutes to conduct research and development and trial production of new seed 109 tapes.
[0041] As a preferred embodiment, the pneumatic reciprocating feeding mechanism includes a pneumatic seed-picking rod 104 and a reciprocating moving component. The pneumatic seed-picking rod 104 is connected to a negative pressure pipeline 106 with an air pump 105. The negative pressure pipeline 106 can generate negative pressure at the seed-picking end of the pneumatic seed-picking rod 104 to adsorb the seeds 109. The reciprocating moving component can drive the pneumatic seed-picking rod 104 to reciprocate during the seed-feeding stroke. It is understood that, in order to facilitate the absorption and release of the seeds 109, the seed-picking end of the pneumatic seed-picking rod 104 is preferably a rubber ring structure. The rubber ring and the negative pressure pipeline 106 form a negative pressure suction cup that can adsorb the seeds 109. In addition, it is understood that, in order to reduce the power consumption of the negative pressure pipeline 106, the negative pressure pipeline 106 is preferably connected to the seed-picking end of the pneumatic seed-picking rod 104 to reduce the negative pressure stroke.
[0042] like Figure 3 The diagram shown is a front view of the reciprocating moving component provided in this embodiment. As can be seen from the diagram, the reciprocating moving component is fixed to the bracket A101, and its height is adapted to the center height of the weaving assembly. The reciprocating moving component includes a cylindrical roller 103 and a drive motor A102 that drives the roller 103 to rotate. A curved travel groove 116 is provided on the outer periphery of the roller 103, arranged along its length and surrounding the outer periphery to form a curve. A pneumatic seed-taking rod 104 is mounted above the roller 103 and slides with the travel groove 116 via a guide wheel 114. In use, the roller 103 is driven... The motor A102 drives the rotation, which in turn drives the stroke groove 116 to rotate. At this time, the guide wheel 114 is limited and guided by the stroke groove 116 to move relative to the stroke groove 116, thereby driving the pneumatic seed-taking rod 104 to reciprocate in the horizontal direction. It can be seen that in this embodiment, the curved stroke groove 116 serves as both the driving groove and the limiting groove of the pneumatic seed-taking rod 104, ensuring that the pneumatic seed-taking rod 104 reciprocates within the effective stroke. Of course, the above is a structural schematic diagram of a preferred reciprocating moving part in this embodiment. In other embodiments of this application, the reciprocating moving part can also be a telescopic cylinder that meets the required stroke.
[0043] To prevent the pneumatic seed-taking rod 104 from deviating from its effective stroke during movement and to improve the stability of its movement, this embodiment preferably uses a limiting frame to support and limit both ends of the pneumatic seed-taking rod 104. This limiting frame can limit the pneumatic seed-taking rod 104 directly above the roller 103, preventing the pneumatic seed-taking rod 104 from rotating with the roller 103 and causing a stroke deviation. It is understood that a U-shaped groove or a limiting ring can be provided on the limiting frame to slide with the pneumatic seed-taking rod 104.
[0044] As a preferred embodiment, limit sensors 113 are provided at both ends of the roller 103. The limit sensors 113 can be limit switches or proximity switches. A fixing ring 115 is provided on the pneumatic seed-taking rod 104. When the fixing ring 115 moves with the pneumatic seed-taking rod 104, it can contact the limit sensors 113 to control the opening and closing of the negative pressure pipeline 106 and the start and stop of the drive motor A102.
[0045] Specifically, limit sensors 113 are respectively installed on the limit frames at both ends of the roller 103 to support the pneumatic seed-taking rod 104. When the limit sensor 113 located at the front end of the roller 103 (referred to as limit sensor A) is triggered, it controls the negative pressure pipeline 106 to be connected, thereby providing negative pressure adsorption force to the pneumatic seed-taking rod 104 for seed taking. When the limit sensor 113 located at the rear end of the roller 103 (referred to as limit sensor B) is triggered, it controls the negative pressure pipeline 106 to be disconnected, thereby cutting off the negative pressure adsorption force of the pneumatic seed-taking rod 104 to release the seed 109. At the same time, it also controls the start and stop of the drive motor A102 to control the pneumatic seed-taking rod 104 to move forward or backward.
[0046] As a preferred embodiment, a seed-taking tray 108 is provided inside the seed box 110. The seed-taking tray 108 has seed-taking holes arranged at equal intervals. When the seed-taking tray 108 rotates, it can carry a quantitative amount of seeds 109 from the seed box 110 and fall down, thereby providing a basis for the pneumatic seed-taking rod 104 to take seeds quantitatively and evenly. In this embodiment, the seed box 110 is preferably fixed on the wall of the vertical base plate 2, and its height is adapted to the pneumatic seed-taking rod 104. After the pneumatic seed-taking rod 104 adsorbs the seeds 109 from the seed box 110, it transports the seeds 109 to the seed braiding ring 214 through the coaxially arranged through opening.
[0047] like Figure 4The diagram shows a partial cross-sectional view of the seed box 110 provided in this embodiment. As can be seen, the seed box 110 includes a seed storage compartment and a seed dispensing compartment, which are connected by a connecting port. The seed dispensing tray 108 is a vertical disc positioned at the connecting port, ensuring that seeds 109 falling from the connecting port can enter the seed dispensing tray 108 through the seed dispensing holes on the vertical disc, thus being quantitatively and evenly discharged. In this embodiment, the seed dispensing tray 108 is connected to the drive motor B111 via a connecting rod 112, meaning that the drive motor B111 drives the seed dispensing tray 108 to rotate, thereby dispensing and picking up seeds. In this embodiment, preferably, the triggering of the drive motor B111 is controlled by a limit switch A, specifically linked to the startup procedure of the negative pressure pipeline 106. That is, while the negative pressure pipeline 106 is activated to provide negative pressure suction, the drive motor B111 drives the seed dispensing tray 108 to rotate. The pneumatic seed-taking rod 104 is then used for sowing. It is understood that the seed-taking end of the pneumatic seed-taking rod 104 should be located at the seed inlet 107 of the seed-taking disc 108, thus achieving effective adsorption of the seeds 109. In this embodiment, the pneumatic seed-taking rod 104 is preferably positioned below the seed inlet 107 and moves back and forth relative to it. Specifically, when the pneumatic seed-taking rod 104 retracts, its seed-taking end moves to the seed inlet 107 to adsorb the seeds 109 (seed taking). When it advances, it blocks the seed hole through the rod body of the pneumatic seed-taking rod 104, and simultaneously transports the seeds 109 to the seed braiding ring 214 through the seed-taking end. In this embodiment, a spring contact is preferably provided below the seed inlet 107. The pneumatic seed-taking rod 104 is pressed down when it passes by, and springs up again when it retracts to adsorb seeds. This spring contact is used to buffer and protect the pneumatic seed-taking rod 104.
[0048] As a preferred embodiment, a seed delivery limiting tube 207 extending to the seed braiding ring 214 is provided at the through opening of the vertical substrate 2. The seed delivery limiting tube 207 is coaxially arranged with the seed braiding ring 214. It can be understood that the diameter of the seed delivery limiting tube 207 should be larger than the diameter of the pneumatic seed-taking rod 104, so that the pneumatic seed-taking rod 104 can pass through. At the same time, the setting of the seed delivery limiting tube 207 can improve the seed delivery accuracy of the pneumatic seed-taking rod 104 and avoid the occurrence of positional deviation.
[0049] In a preferred embodiment, the rope winding assembly includes a rope-guiding rubber ring 302, a rope-arranging assembly, and a rope winding disc 305 arranged sequentially from front to back. The rope-guiding rubber ring 302 is coaxially arranged with the seed braiding ring 214 to limit the forward direction of the seed rope 401 and guide it to the rope-arranging assembly. The rope-arranging assembly is used to drive the seed rope 401 to move back and forth to evenly wind the seed rope 401 onto the rope winding disc 305. In this embodiment, the rope-arranging assembly includes a rope-guiding rod 303, a drive motor E308, a lead screw 306, and a nut seat 307. Rod 303 is fixed on nut seat 307. When drive motor E308 drives lead screw 306 to rotate, nut seat 307 will reciprocate relative to lead screw 306, thereby driving guide rod 303 to move. Under the periodic movement of guide rod 303, the contact point between spiral braided rope (seed rope 401) and winding reel 305 can be changed, ensuring that seed rope 401 is evenly wound on winding reel 305. Winding reel 305 is driven by drive motor D304. Winding reel 305 is a detachable structure, which is beneficial for the storage and transportation of seed rope 401.
[0050] In a preferred embodiment, the braiding assembly is fixed to the side of the vertical base plate 2 near the feeding assembly. This braiding assembly includes a gear assembly and a spindle assembly. The gear assembly includes a drive gear 212 that meshes with each other and multiple sets of pinions 208, such as... Figure 5 As shown, the drive gear 212 is driven by the drive motor C206. The drive gear 212 is mounted on the vertical base plate 2 via the fixed shaft II 209. Multiple sets of pinions 208 are arranged in a circular array on the vertical base plate 2 via the fixed shaft I 213 and are located on the outer periphery of the through opening. The number of spindle assemblies corresponds to the number of pinions 208, and each spindle assembly includes a yarn carrier 205 and a limiting column head 211. The spindle assembly is fixed to the pinion 208 via the limiting column head 211 and rotates with the pinion 208, thereby driving the yarn carrier 205 to rotate for cross-knitting of the yarn harness 215.
[0051] Specifically, an upper limit plate 201 is installed on the fixed shaft II 209. The upper limit plate 201 is located on the upper part of the pinion 208. The pinions 208 installed on each fixed shaft I 213 are meshed with each other. The drive motor C 206 drives the drive gear 212 to drive one of the pinions 208. The pinions 208 are meshed with each other to drive each pinion 208. Four slots 210 are opened on the circumference of the pinion 208. The limiting post head 211 at the bottom of the spindle assembly is closely set at the corresponding slot 210 position. When the pinion 208 rotates, it drives the spindle assembly to move to the next pinion 208 to achieve cross-knitting. The yarn carrier 205 is installed on the yarn carrier disc 204 on the upper part of the spindle assembly. The yarn carrier disc 204 is fixed on the upper limit plate 201.
[0052] In this embodiment, the vertical substrate 2 has a hollow structure, the gear assembly is installed in the hollow cavity of the vertical substrate 2, and a motion guide rail 203 is provided on the rear end face of the vertical substrate 2. The motion guide rail 203 is used to limit and guide the spindle assembly, ensuring that the spindle assembly slides within the limiting track; according to Figure 1 As can be seen, the motion guide rail 203 in this embodiment is composed of an upper limit plate 201 and the rear end face of a vertical base plate 2; the yarn carrier 205, which is equipped with a yarn bobbin, moves clockwise or counterclockwise along the motion guide rail 203 to guide the yarn to form a secondary spiral structure, thereby realizing the interweaving of adjacent yarns to form a spiral braided rope, and then wrapping the seed 109 in the seed braiding ring 214.
[0053] In this embodiment, the spindle assembly also includes a boat-shaped guide block 216, which plays a guiding role when the spindle assembly moves along the limiting trajectory.
[0054] It is understood that in this embodiment, the model and power of the drive motor A102-E can be selected according to the actual working conditions, and this embodiment does not make specific limitations here.
[0055] The specific operating principle of this embodiment includes:
[0056] Before use, add enough seeds 109 to the seed box 110 and install the yarn tube on the yarn carrier 205;
[0057] In use, first activate the negative pressure pipeline 106 to provide negative pressure suction to the pneumatic seed-picking rod 104. Simultaneously, activate the drive motor B111 to rotate the seed-picking disc 108 to ensure the pneumatic seed-picking rod 104 picks up seeds normally. Then, activate the drive motor A102 to drive the roller 103 to rotate clockwise, moving the pneumatic seed-picking rod 104 towards the seed braiding ring 214 via the stroke groove 116. When the limit sensor B is triggered, the pneumatic seed-picking rod 104 will have just moved to the position of the seed braiding ring 214. At this point, the drive motor A102 stops rotating clockwise. When the negative pressure is released from the negative pressure pipeline 106, the pneumatic seed-taking rod 104 releases the seeds 109 and retracts under the counterclockwise rotation of the drive motor A102. In this embodiment, the braiding assembly and the rope winding assembly can be started during the seed delivery process of the pneumatic seed-taking rod 104. The released seeds 109 will be wrapped in the multi-strand braided wire bundle 215 at the seed braiding ring 214 position to form the seed rope 401. When the pneumatic seed-taking rod 104 retracts to the position, the limit sensor A will be triggered. At this time, the negative pressure pipeline 106 and the drive motor B111 will be started again to take seeds, and the cycle will repeat in sequence.
