Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to a seed mixing device for agricultural planting. Background Technology

[0002] Seed mixing devices for agricultural planting are specialized equipment used in the field of agricultural planting. Their main function is to uniformly mix seeds with pesticides, fertilizers, or other protective agents, so that the agent is evenly coated on the surface of each seed. Through this treatment, seeds can be effectively prevented from being attacked by pests and diseases after sowing, the germination rate of seeds and the survival rate of seedlings can be improved, and the workload of subsequent field application can be reduced. It is an important link in agricultural production to ensure seed quality and promote healthy crop growth.

[0003] However, existing seed-mixing devices for agricultural planting have many shortcomings in practical applications:

[0004] Most of the equipment does not have a top cover structure. During the mixing process, seeds and pesticides are easily splashed due to the centrifugal force generated by stirring, which not only wastes materials, but may also cause operators to come into contact with toxic agents, posing a safety hazard.

[0005] The spraying of pesticides is mostly done manually. Manual spraying makes it difficult to ensure the uniformity of pesticide distribution, and it is easy to have too much or too little pesticide in some areas, which affects the effect of mixing.

[0006] For drugs that need to be diluted with water or mixed with other drugs, existing devices lack a dedicated mixing mechanism. The mixing process must be carried out manually, which not only increases the labor intensity of operators, but also makes it difficult to accurately control the proportions and easily leads to uneven mixing, thus affecting the efficacy of the drug.

[0007] Therefore, it is necessary to provide a new seed-mixing device for agricultural planting to solve the above-mentioned technical problems. Utility Model Content

[0008] To solve the above-mentioned technical problems, this utility model provides a seed mixing device for agricultural planting.

[0009] The present invention provides a seed mixing device for agricultural planting, comprising: 1. A seed mixing device for agricultural planting, characterized in that it comprises: a mixing cylinder, wherein rotating rods are symmetrically fixedly connected to the outer wall of the mixing cylinder, and a support is provided at the bottom of the mixing cylinder, the rotating rods being rotatably connected to the support; a first connecting rod is rotatably connected inside the mixing cylinder, and multiple sets of first stirring rods for stirring seeds are fixedly connected at equal intervals to the outer wall of the first connecting rod; a top cover is installed on the top of the mixing cylinder, and limiting blocks are symmetrically installed on the edge of the top cover; a limiting ring is installed on the top of the mixing cylinder, and the limiting blocks limit the top cover to the top of the mixing cylinder by engaging with the limiting ring; a storage cylinder is fixedly connected to the top of the top cover, and a second connecting rod is rotatably connected inside the storage cylinder, and multiple sets of second stirring rods for stirring medicine are fixedly connected at equal intervals to the outer wall of the second connecting rod; a pump body is installed on the top of the top cover, and the input end of the pump body is connected to the bottom of the storage cylinder through a pipe; a nozzle is fixedly connected to the inner wall of the top cover, and the output end of the pump body is connected to the top of the nozzle through a pipe.

[0010] Preferably, a driven gear is rotatably connected inside one end of the bracket, and the driven gear is fixed to the rotating rod; a driving gear is rotatably connected inside the end of the bracket near the driven gear, and the driving gear meshes with the driven gear.

[0011] Preferably, a first motor is fixedly connected inside the bracket at one end near the drive gear, and the output end of the first motor is fixedly connected to the drive gear.

[0012] Preferably, the top cover is symmetrically and fixedly connected with handrails, and the inside of the handrails has a sliding groove, in which the limiting block slides.

[0013] Preferably, compression springs are symmetrically installed in the slide groove, with one end of the compression spring fixed to the inner wall of the handrail and the other end of the compression spring fixed to the limiting block.

[0014] Preferably, a lever is fixedly connected to the bottom of the limiting block, and the lever is used to move the limiting block.

[0015] Preferably, a locking block is fixedly connected to the top of the first connecting rod, and a locking groove is provided at the bottom of the second connecting rod. Both the locking block and the locking groove are square, and the locking block and the locking groove are engaged.

[0016] Preferably, a second motor is fixedly connected to the bottom of the mixing drum, and the output end of the second motor is fixed to the first connecting rod; the friction between the top cover and the mixing drum is greater than the friction between the second connecting rod and the storage drum.

[0017] Compared with related technologies, the seed mixing device for agricultural planting provided by this utility model has the following advantages:

[0018] Beneficial effects:

[0019] Effectively prevents material splashing and improves operational safety.

[0020] The mixing drum of this invention is equipped with a fixed top cover. The top cover can be firmly fixed to the top of the mixing drum through the snap-fit ​​structure of the limiting block and the limiting ring. During the mixing process, the top cover can effectively prevent the seeds and pesticides from splashing due to the centrifugal force generated by stirring, thus avoiding material waste. At the same time, it reduces the direct contact between operators and toxic agents, reduces safety hazards, and solves the problem of material splashing and safety risks caused by the lack of a top cover in existing devices.

[0021] To achieve automatic spraying and mixing of drugs and improve the mixing effect.

[0022] Automatic pesticide spraying: The device is equipped with a storage tank, a pump and a nozzle. The pump draws pesticide from the storage tank through a pipeline and delivers it to the nozzle. The nozzle atomizes the pesticide and sprays it evenly into the mixing tank. No manual spraying is required, which ensures the uniformity of pesticide spraying and avoids the situation of excessive or insufficient pesticide in some areas when spraying manually, thus improving the mixing effect of seeds and pesticides.

[0023] Drug pre-mixing: Driven by the second motor (through the snap-fit ​​transmission between the first and second connecting rods), the second connecting rod and the second stirring rod inside the drug storage cylinder can stir the drug in the storage cylinder. For drugs that need to be diluted with water or mixed with other drugs, automatic mixing can be completed in the storage cylinder without manual mixing, ensuring the uniformity of drug mixing and solving the problem of existing devices relying on manual drug mixing and poor mixing effect.

[0024] Easy to operate and improves work efficiency

[0025] Easy to install and remove the top cover: The handle on the edge of the top cover makes it easy to move the top cover. The limit block can be easily moved by the lever to realize the engagement and disengagement of the limit block and the limit ring, thereby quickly completing the installation and disassembly of the top cover.

[0026] The mixing drum angle is adjustable: the first motor drives the active gear, driven gear and rotating rod to rotate, and the angle of the mixing drum can be flexibly adjusted; when mixing, the mixing drum is adjusted to a horizontal position to facilitate uniform mixing of seeds; when picking up seeds, the mixing drum is adjusted to a tilted position to facilitate pouring out the seeds, eliminating the need for manual handling and pouring, saving manpower and improving work efficiency.

[0027] Highly efficient power transmission: The first connecting rod and the second connecting rod are engaged with the slot by a square block. When the second motor drives the first connecting rod to rotate, it can synchronously drive the second connecting rod to rotate, realizing the synchronous operation of seed mixing and drug mixing. In addition, the friction design between the top cover and the mixing cylinder ensures that the power is only transmitted to the second connecting rod and does not drive the top cover to rotate, thus ensuring the stability and efficiency of the operation of each component.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0035] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0036] Please see Figures 1 to 5A seed mixing device for agricultural planting includes: a mixing cylinder 1, with rotating rods 2 symmetrically fixedly connected to the outer wall of the mixing cylinder 1, and a support 3 at the bottom of the mixing cylinder 1, the rotating rods 2 and the support 3 being rotatably connected; a first connecting rod 4 rotatably connected inside the mixing cylinder 1, with multiple sets of first stirring rods 5 for stirring seeds fixedly connected at equal intervals to the outer wall of the first connecting rod 4; a top cover 6 installed on the top of the mixing cylinder 1, with limiting blocks 7 symmetrically installed on the edge of the top cover 6, and a limiting ring 8 installed on the top of the mixing cylinder 1, the limiting blocks 7 limiting the top cover 6 to the top of the mixing cylinder 1 by engaging with the limiting ring 8; a storage cylinder 9 fixedly connected to the top of the top cover 6, with a second connecting rod 10 rotatably connected inside the storage cylinder 9; and a second... Multiple sets of second stirring rods 11 for stirring medicine are fixedly connected at equal intervals to the outer wall of the connecting rod 10; a pump body 12 is installed on the top of the top cover 6, and the input end of the pump body 12 is connected to the bottom of the medicine storage cylinder 9 through a pipe; a nozzle 13 is fixedly connected to the inner wall of the top cover 6, and the output end of the pump body 12 is connected to the top of the nozzle 13 through a pipe; a locking block 21 is fixedly connected to the top of the first connecting rod 4, and a locking groove 22 is opened at the bottom of the second connecting rod 10. Both the locking block 21 and the locking groove 22 are square, and the locking block 21 and the locking groove 22 are engaged; a second motor 23 is fixedly connected to the bottom of the mixing cylinder 1, and the output end of the second motor 23 is fixed to the first connecting rod 4; the friction between the top cover 6 and the mixing cylinder 1 is greater than the friction between the second connecting rod 10 and the medicine storage cylinder 9.

[0037] It should be noted that the friction between the top cover 6 and the mixing cylinder 1 is greater than the friction between the second connecting rod 10 and the storage cylinder 9, so that when the second motor 23 drives the first connecting rod 4 to rotate, the first connecting rod 4 only drives the second connecting rod 10 to rotate through the engagement of the locking block 21 and the locking groove 22, and does not drive the top cover 6 to rotate; the nozzle 13 is an atomizing nozzle 13.

[0038] Please see Figure 1 and Figure 2 A driven gear 14 is rotatably connected inside one end of the bracket 3, and the driven gear 14 is fixed to the rotating rod 2; a driving gear 15 is rotatably connected inside the end of the bracket 3 near the driven gear 14, and the driving gear 15 meshes with the driven gear 14; a first motor 16 is fixedly connected inside the end of the bracket 3 near the driving gear 15, and the output end of the first motor 16 is fixedly connected to the driving gear 15.

[0039] It should be noted that: the driven gear 14 and the rotating rod 2 are driven to rotate by the driving gear 15, thereby adjusting the angle of the mixing drum 1. When stirring is required, the mixing drum 1 is made horizontal. When the seeds are taken out, the mixing drum 1 is tilted to pour out the seeds. The first motor 16 is a stepper motor. When the first motor 16 is not powered, the output shaft of the first motor 16 will not rotate.

[0040] Please see Figure 2 and Figure 3 The top cover 6 is symmetrically and fixedly connected to the edge of the handrail 17. The handrail 17 has a sliding groove 18 inside, and the limiting block 7 slides in the sliding groove 18. A compression spring 19 is symmetrically installed in the sliding groove 18. One end of the compression spring 19 is fixed to the inner wall of the handrail 17, and the other end of the compression spring 19 is fixed to the limiting block 7. A toggle block 20 is fixedly connected to the bottom of the limiting block 7. The toggle block 20 is used to move the limiting block 7.

[0041] It should be noted that when placing the top cover 6 on top of the mixing cylinder 1, the top cover 6 needs to be twisted to ensure that the locking block 21 is engaged with the locking groove 22 before the top cover 6 can fit against the mixing cylinder 1 and the limiting block 7 can engage with the limiting ring 8. When it is necessary to remove the seeds, the top cover 6 needs to be removed first before rotating the mixing cylinder 1.

[0042] The working principle of the seed mixing device for agricultural planting provided by this utility model is as follows:

[0043] Seed release stage

[0044] In the initial state, the top cover 6 is not installed, and the seeds to be mixed are directly added into the mixing cylinder 1. At this time, the mixing cylinder 1 is kept stable by the support 3. The rotation connection between the rotating rod 2 and the support 3 is reserved for subsequent angle adjustment. The seeds naturally accumulate at the bottom of the mixing cylinder 1 under the action of gravity.

[0045] Top cover installation and fixing stage 6

[0046] The top cover 6 is moved to the top of the mixing cylinder 1 via the handle 17. The lever 20 is moved to make the limiting block 7 slide along the slide groove 18 and compress the spring 19 (at this time, the limiting block 7 and the limiting ring 8 are separated). The top cover 6 is twisted so that the square locking block 21 at the top of the first connecting rod 4 is fully embedded in the square locking groove 22 at the bottom of the second connecting rod 10, realizing the mechanical linkage between the two. This operation also ensures that the top cover 6 is in contact with the top surface of the mixing cylinder 1, creating conditions for the subsequent locking of the limiting block 7. After the lever 20 is released, the compressed spring 19 releases its elastic potential energy, pushes the limiting block 7 to reset and locks with the limiting ring 8, and the top cover 6 is firmly fixed to the top of the mixing cylinder 1. At this time, the friction between the top cover 6 and the mixing cylinder 1 is greater than the rotational friction between the second connecting rod 10 and the storage cylinder 9 (providing a basis for subsequent power transmission).

[0047] Drug Addition and Delivery Stage

[0048] Drug storage: The required drugs are injected into the drug storage cylinder 9, and the drugs are temporarily stored in the drug storage cylinder 9, awaiting delivery;

[0049] Power drive and drug stirring: Start the second motor 23, and its output end drives the first connecting rod 4 to rotate; due to the rigid connection between the locking block 21 and the locking slot 22, the second connecting rod 10 rotates synchronously with the first connecting rod 4, and the second stirring rod 11 on the outer wall stirs the drug in the drug storage cylinder 9 to ensure that the drug is mixed evenly.

[0050] Drug spraying: Start the pump body 12. Its input end draws the stirred drug from the bottom of the drug storage cylinder 9 through the pipeline, and the output end pressurizes and delivers the drug to the nozzle 13 on the inner wall of the top cover 6 through the pipeline. The drug is atomized by the nozzle 13 and sprayed evenly on the seed surface in the mixing cylinder 1.

[0051] Seed dressing stage

[0052] While the drug is being sprayed, the first connecting rod 4 continues to rotate, and the first stirring rod 5 on the outer wall turns the seeds inside the mixing cylinder 1. Since the mixing cylinder 1 is in a horizontal state (adjusted to position by the first motor 16 driving the drive gear 15, driven gear 14 and rotating rod 2), the seeds move irregularly under the action of stirring force, making full contact with and adsorbing the atomized drug, thus achieving uniform mixing.

[0053] Seed collection stage

[0054] Unlock the top cover 6: Move the lever 20 to disengage the limit block 7 from the limit ring 8, release the top cover 6 from the fixation, and lift the handle 17 upwards to remove the top cover 6 (at this time, the locking block 21 separates from the locking groove 22).

[0055] Angle adjustment for seed collection: Start the first motor 16, the drive gear 15 drives the driven gear 14 and the rotating rod 2 to rotate, so that the mixing cylinder 1 is tilted, and the seeds are poured out from the mixing cylinder 1 under the action of gravity, thus completing the entire mixing process.

[0056] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
