DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] To deepen the understanding of the present utility model, the following will further elaborate on the present utility model in conjunction with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation to the protection scope of the present utility model.

[0020] According to Figure 1 - Figure 4 As shown, this embodiment proposes a double-row fertilizing automatic small-seed adjustable seeder, including a seeder connecting frame 1. The seeder connecting frame 1 includes two groups of horizontally arranged plates 20 that are symmetrically arranged up and down. Among them, the length of the upper horizontal plate 20 is less than that of the lower horizontal plate 20. The two groups of horizontal plates 20 are connected by fixing plates 21, and several groups of fixing plates 21 are provided. In this embodiment, two groups of fixing plates 21 are symmetrically arranged, and the fixing plates 21 are provided with openings. The seeder connecting frame 1 composed of the horizontal plates 20 and the fixing plates 21 is used to connect with the hydraulic lifting device of an external tractor, so that this device is suspended on the hydraulic lifting device of the tractor, and the seeder is towed by the tractor to operate, and the lifting operation of the seeder is implemented by the hydraulic lift of the tractor, and the opening and sowing depth of the seeder is controlled to be between 30 cm and 100 cm.

[0021] A seeding and fertilizing device is installed above the seeder connecting frame 1. Among them, the seeding and fertilizing device includes a double-link seed and fertilizer box 8, a double-link seeding and fertilizing device 9, and a double-link seed and fertilizer discharging box 10. The double-link seeding and fertilizing device 9 is installed below the double-link seed and fertilizer box 8, and the double-link seed and fertilizer discharging box 10 is installed below the double-link seeding and fertilizing device 9. Specifically, the double-link seed and fertilizer box 8 is connected to the seeder connecting frame 1 through a seeder bracket 25. The double-link seed and fertilizer box 8 is used for storing seeds and fertilizers. At the same time, the inner cavity of the double-link seed and fertilizer box 8 is communicated with the double-link seeding and fertilizing device 9. Therefore, the seeds and fertilizers stored in the double-link seed and fertilizer box 8 can enter the double-link seeding and fertilizing device 9 and be discharged through it and enter the double-link seed and fertilizer discharging box 10.

[0022] Furthermore, two groups of symmetrically arranged seed and fertilizer discharging wheels 13 are installed inside the double-link seeding and fertilizing device 9. The seed and fertilizer discharging wheels 13 are driven by a speed regulating motor 14. The inner cavity of the double-link seeding and fertilizing device 9 is communicated with the double-link seed and fertilizer discharging box 10. In this embodiment, the speed regulating motor 14 is located outside the double-link seeding and fertilizing device 9 and is connected to the double-link seeding and fertilizing device 9 through a bracket. Specifically, a speed regulating switch is added to the speed regulating motor 14 to set the speed of the speed regulating motor 14 to be adjusted in ten gears, so as to meet the requirements of different seeding amounts. For parameters such as seeding area and seeding amount, the rotation speed of the motor is adjusted by the switch gear of the speed regulating switch to control the seeding amount.

[0023] Among them, the seeding and fertilizing wheel 13 includes a seeding and fertilizing round shaft 17, and the seeding and fertilizing round shaft 17 is composed of a composite of a PVC plastic sleeve and steel. That is, the central part of the seeding and fertilizing round shaft 17 is a steel shaft, and a PVC plastic sleeve is sleeved outside the steel shaft. Honeycomb hole seed holes 18 are formed on the seeding and fertilizing round shaft 17, that is, they are formed on the PVC plastic sleeve. Several groups of honeycomb hole seed holes 18 are evenly provided, and the sizes of several groups of honeycomb hole seed holes 18 are different. This design is mainly to adapt to the particle sizes of seeds of various plant varieties and achieve multi-purpose use of one machine.

[0024] Both ends of the seeding and fertilizing round shaft 17 are connected to the double-row seeding and fertilizing device 9 through bearings. At the same time, one end of each of the two seeding and fertilizing round shafts 17 extends to the outside of the double-row seeding and fertilizing device 9, and a pulley 19 is installed. The two pulleys 19 are connected by a belt. Therefore, in this embodiment, the output shaft of the speed-regulating motor 14 only needs to be connected to one of the seeding and fertilizing round shafts 17, and then drive one of the seeding and fertilizing round shafts 17 to rotate through the speed-regulating motor 14, and drive the other seeding and fertilizing round shaft 17 to rotate through the cooperation of the pulley 19 and the belt.

[0025] A sealing felt 23 is installed at the upper end of the double-row seeding and fertilizing device 9. The sealing felt 23 mainly prevents fertilizers and seeds from directly entering the double-row seeding and fertilizing device 9. Two symmetrically arranged material discharge ports 24 are provided on the sealing felt 23, and the positions of the material discharge ports 24 correspond to the two seeding and fertilizing wheels 13 respectively. Therefore, seeds and fertilizers pass through the material discharge ports 24 and the seeding and fertilizing wheels 13.

[0026] Both ends of the seeding machine connecting frame 1 are installed with lengthening adjusting arms 2. Installation ports 3 are provided on the lengthening adjusting arms 2. A grooving tool connecting rod 4 is provided on one side of the lengthening adjusting arms 2. A sliding rod 5 is installed inside the installation port 3. A slider 6 is provided on the sliding rod 5, and the slider 6 is connected to the lengthening adjusting arm 2 through a locking component. The slider 6 can move on the sliding rod 5. At the same time, both the upper and lower sides of the slider 6 are in contact with the lengthening adjusting arm 2. The corresponding slider 6 is connected to the grooving tool connecting rod 4. Thus, by adjusting the position of the slider 6, the position of the grooving tool connecting rod 4 can be adjusted. Therefore, in this embodiment, it is supported to adjust the position between the two grooving tool connecting rods 4. A sharp-blade depth grooving plow 7 is installed at the lower end of the grooving tool connecting rod 4. The grooving tool connecting rod 4 and the sharp-blade depth grooving plow 7 form a grooving tool. Therefore, in this device, the distance between the two grooving tools can be adjusted, and the adjustment range is between 2m and 6m to meet the requirements of different tree species such as Haloxylon ammodendron forest, Tamarix ramosissima forest, and Nitraria tangutorum forest for different row spacings and planting depths when sowing Cistanche deserticola.

[0027] The specific locking component includes two sets of locking members 15 arranged symmetrically. On both the upper and lower sides of the slider 6, limiting openings 16 are provided on the lengthening adjusting arm 2. The length of the limiting opening 16 is the same as that of the mounting opening 3. One end of the locking member 15 passes through the limiting opening 16 and is connected to the slider 6 by threads. In this embodiment, the locking member 15 corresponds to a bolt. Therefore, after the locking member 15 is completely connected to the slider 6, a part of the locking member 15 is in close contact with the lengthening adjusting arm 2. Thus, the clamping force and frictional force generated by the close contact are used to achieve the fixing effect. When adjustment is required, only loosen it. On both sides of the corresponding limiting opening 16, scale indicating lines 22 are provided on the lengthening adjusting arm 2. By the scale on the scale indicating line 22 corresponding to the locking member 15, the distance between the two sets of furrow openers can be determined.

[0028] Specifically, two sets of inspection tubes 11 arranged symmetrically are installed at the lower end of the double-row seed and fertilizer box 10. Two discharge ports are provided at the lower end of the double-row seed and fertilizer box 10, and the discharge ports are communicated with the inspection tubes 11. A seed and fertilizer conveying pipe 12 is installed on the furrow opener connecting rod 4, and the seed and fertilizer conveying pipe 12 is connected to the inspection tube 11. In this embodiment, the inspection tube 11 is a flexible tube, which can adapt to the furrow opener connecting rod 4 at different positions. The lower end of the seed and fertilizer conveying pipe 12 is located at the tail end of the furrow opener, and it is a component that uniformly and continuously conveys the seeds sown by the seeder to the tail groove of the furrow opener. Then, the double-row seed and fertilizer box 10 plays the role of transferring seeds and fertilizers, enabling them to enter the seed and fertilizer conveying pipe 12 through the inspection tube 11 and then be conveyed to the end groove of the furrow opener to complete the sowing and fertilizing operation.

[0029] This device adds the fertilizing function to the seeder. While performing the sowing operation, it completes the fertilizing operation, increases the uses of the seeder, and improves the planting efficiency. Similar to the sowing operation, it can be adjusted according to the fertilizer application amount required for different plant varieties.

[0030] This utility model uses a large tractor as the power to drive this device to operate between the rows of Haloxylon ammodendron, Nitraria tangutorum, and Tamarix ramosissima forests in the sandy area, solving the problems of high labor intensity, large labor consumption, and high labor cost in the artificial planting of Cistanche deserticola and Cynomorium songaricum.

[0031] The utility model adopts two pointed share deep furrow plows for furrow opening and sowing, and the sowing row spacing of the two furrow plows can be adjusted to meet the different sowing row spacing requirements of different tree species such as Haloxylon ammodendron forest, Tamarix ramosissima forest, and Nitraria tangutorum forest for sowing plants such as Cistanche deserticola and Cynomorium songaricum. At the same time, it is connected to the hydraulic lifting device of an external tractor through a seeding machine connecting frame. Therefore, the pointed share deep furrow plows can be used to meet the planting requirements of different plants such as Cistanche deserticola and Cynomorium songaricum with different sowing depths, solving the problems of inconvenient adjustment and adaptation in the prior art. At the same time, the seed metering and fertilizer application wheel is a special honeycomb hole type seed metering wheel, which is provided with several groups of honeycomb hole seed holes with different sizes, so as to meet the different particle sizes of different plant seeds, overcoming the defect that ordinary grain and forage seeders cannot be used for sowing different plant seeds, and realizing multi-purpose of one machine.
