Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural machinery technology, and in particular relates to a fan transmission and temperature control device for an air-blowing seeder. Background Technology
[0002] An air-blowing seeder is an agricultural machine that uses airflow for precision seeding. It is suitable for high-speed operation and can quickly and accurately sow seeds into the soil while simultaneously completing processes such as fertilization and soil covering, ensuring that each seed has the appropriate spacing and depth.
[0003] In simple terms, after cleaning and screening, the seeds are placed in a seed box; then the seeds are conveyed to the nozzle; subsequently, the compressed air device inside the seeder compresses the air to a certain pressure and delivers it to the nozzle system. The compressed air lifts the seeds from the seed box and mixes them with the air, and finally the seeds are sprayed onto the soil in the form of a mist. However, most existing air-blowing seeders use a single-channel direct-blowing structure, which results in too low an air speed, affecting the accuracy of the seeds falling into the soil during sowing. Therefore, a fan drive and temperature control device for air-blowing seeders is needed to solve the above problems. Utility Model Content
[0004] The purpose of this utility model embodiment is to provide a fan drive and temperature control device for an air-blowing seeder, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A fan drive and temperature control device for an air-blowing seeder includes:
[0007] Equipment body;
[0008] An air blowing assembly, comprising an air blower, a fan duct, and a drive unit, wherein the fan duct is connected to one end of the air blower, the drive unit is disposed on the air blower, the fan duct is horizontally installed at the front end of the main body of the equipment, and the fan duct is configured as U-shaped;
[0009] The seeding assembly includes a seeding tube and a seed box. One end of the seed box is connected to one end of the fan duct, and the other end of the seed box is sealed. There are two sets of seeding tubes, and each set has multiple seeding tubes. The multiple seeding tubes are spaced apart from the seed box and connected to the seed box. There is a pair of seed boxes, and the pair of seed boxes are respectively installed at both ends of the fan duct.
[0010] In a further technical solution, the main body of the device has an air intake, which is V-shaped and connected to the air blower.
[0011] In a further technical solution, the air blowing assembly also includes a suction filter element, which is installed on the main body of the device. There are two suction filters, which are respectively located at both ends of the V-shaped air intake.
[0012] In a further technical solution, the main body of the equipment also includes a fixing plate, which is fixedly installed between the air intake filter and the air blower, and the axial direction of the fixing plate is parallel to the axial direction of the blower duct.
[0013] In a further technical solution, the seeding tube is set as a short channel of 0.5-1.2 meters.
[0014] In a further technical solution, the driving component is set as a hydraulic motor, and the blower has a built-in high-speed rotating impeller with a rotation speed of up to 3000-4000 r / min.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This invention comprises an air-blowing component and a seeding component. The air-blowing component includes an air blower, a fan duct, and a drive unit. The fan duct is connected to the air blower, and the drive unit is located on the air blower. The fan duct is horizontally installed at the front end of the main body of the equipment. The seeding component includes seeding tubes and seed boxes. One end of the seed box is connected to one end of the fan duct. Multiple seeding tubes are spaced apart in the seed box, and the seed boxes are installed at both ends of the fan duct. After the air blower is started, air enters the fan duct and then enters a pair of seed boxes at both ends of the fan duct. The airflow creates a positive pressure environment in the seed boxes. By setting a pair of seed boxes and two sets of spaced seeding tubes at both ends of the fan duct, dual-channel airflow spray is achieved to ensure seed positioning.
[0017] This invention features a seeding tube system with multiple tubes spaced apart in a seed box. The seeding tubes are designed as short channels of 0.5-1.2 meters. After screening, the seeds are accelerated and sprayed through the seeding tubes, ultimately being accurately placed into the soil. By using short-distance seeding tubes, airflow attenuation and seed collisions are reduced, ensuring precise landing.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0026] like Figures 1 to 4 As shown, this utility model embodiment provides a fan drive and temperature control device for an air-blowing seeder, including:
[0027] Equipment body 1;
[0028] Air blowing assembly 2 includes air blower 21, fan duct 22 and drive component 23. The fan duct 22 is connected to one end of the air blower 21. The drive component 23 is disposed on the air blower 21. The fan duct 22 is horizontally installed at the front end of the equipment body 1. The fan duct 22 is U-shaped.
[0029] The seeding assembly 3 includes a seeding pipe 31 and a seed box 32. One end of the seed box 32 is connected to one end of the fan duct 22, and the other end of the seed box 32 is sealed. There are two sets of seeding pipes 31, and each set of seeding pipes 31 has multiple seeding pipes 31. The multiple seeding pipes 31 are spaced apart from the seed box 32 and connected to the seed box 32. There is a pair of seed boxes 32, and the pair of seed boxes 32 are respectively installed at both ends of the fan duct 22.
[0030] In this embodiment, after the air blower 21 is started, air enters the blower duct 22 and then enters a pair of seed boxes 32 at both ends of the blower duct 22. The airflow creates a positive pressure environment in the seed boxes 32. Under the action of the seeds' own gravity and the airflow pressure, individual seeds are screened and excess or damaged particles are removed, with a seed qualification rate of ≥98%. Furthermore, by setting a pair of seed boxes 32 and two sets of spaced-apart sowing pipes 31 at both ends of the blower duct 22, dual-channel airflow jetting is performed to ensure seed positioning.
[0031] Specifically, the main body of the equipment 1 has an air intake 11, which is V-shaped and connected to the air blower 21.
[0032] Specifically, the air blowing assembly 2 also includes a suction filter 24, which is installed on the main body 1 of the equipment. There are two suction filters 24, which are respectively located at the two ends of the V-shaped air intake 11.
[0033] In this embodiment, the air blower 21, once started, causes air to pass through the air intake 11 and enter the blower duct 22 via the air intake filter 24, and then enter the seed boxes 32 at both ends of the blower duct 22.
[0034] Specifically, the main body of the equipment 1 also includes a fixing plate 12, which is fixedly installed between the air suction filter 24 and the air blower 21, and the axial direction of the fixing plate 12 is parallel to the axial direction of the blower duct 22.
[0035] Specifically, the seeding tube 31 is set as a short channel of 0.5-1.2 meters;
[0036] In this embodiment, the selected seeds are accelerated and sprayed through the seeding tube 31, and finally accurately placed into the soil. By setting the seeding tube 31 with a short distance, airflow attenuation and seed collision are reduced, ensuring accurate landing point.
[0037] Specifically, the drive component 23 is a hydraulic motor, and the blower 21 has a built-in high-speed rotating impeller with a rotation speed of up to 3000-4000 r / min;
[0038] In this embodiment, the high-speed rotating impeller accelerates the air through centrifugal force, forming a stable high-pressure airflow.
[0039] The working principle of this utility model is as follows:
[0040] After being started, the blower 21 causes air to pass through the air intake 11 and through the air intake filter 24 into the blower duct 22, and then into a pair of seed boxes 32 at both ends of the blower duct 22. The airflow creates a positive pressure environment in the seed boxes 32. Under the action of the seeds' own gravity and the airflow pressure, individual seeds are screened and excess or damaged particles are removed, with a seed qualification rate of ≥98%. Furthermore, by setting a pair of seed boxes 32 and two sets of spaced-apart sowing pipes 31 at both ends of the blower duct 22, dual-channel airflow spray is provided to ensure seed positioning.
[0041] Subsequently, the selected seeds are accelerated and sprayed through the seeding tube 31, and finally accurately placed into the soil. By setting the seeding tube 31 with a short distance, airflow attenuation and seed collision are reduced, ensuring accurate landing point.
[0042] In addition, after startup, the drive unit 23 drives the air blower 21 and the blower pipe 22 connected to the air blower 21 to adjust their height in the vertical position to meet the needs of different sowing depth adjustments.
[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
