Description

Technical Field

[0001] This utility model relates to the field of millet breeding technology, and in particular to a millet demasting device. Background Technology

[0002] Hybridization is a routine procedure in millet breeding. Currently, the main technical strategy for selecting and breeding new millet varieties remains the traditional hot water emasculation method, which involves hybridization using the traditional method to recombine superior genes. The hot water emasculation method utilizes the different temperature responses of the millet's stamens and pistils. The prepared millet ears are immersed in warm water at 45–47°C for 7–15 minutes to kill the stamens while leaving the pistils undamaged. This method is highly efficient and can emasculate a large number of female ears in a short time.

[0003] Currently, in the process of removing male ears from female plants using the hot water method, the water used after removing male ears from female plants is often wasted because it cannot be reused. As a result, staff need to carry a large amount of hot water to replenish the supply, which greatly increases the workload of the staff and affects work efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the existing technology, such as the large workload of water changing for workers when using the warm water method to remove emasculation from the female ears, and to propose a millet emasculation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a device for removing male fertilization from millet, including a tank and a heating water tank. The heating water tank is located below the tank and is equipped with a filter screen. The heating water tank is equipped with an inlet pipe and an outlet pipe, both of which are connected to the tank. A water pump is installed on the outlet pipe.

[0007] Preferably, a perforated plate is slidably fitted inside the tank, and an agitator is fixedly attached to the perforated plate.

[0008] Preferably, the tank body is provided with a driving structure to drive the perforated plate to rotate. The driving structure includes a bracket, which is fixed to the tank body. An internal spline tube is slidably fitted on the bracket, and a spline shaft is slidably fitted inside the internal spline tube. The bottom of the spline shaft is fixed to the perforated plate. A first gear is fixed to the internal spline tube. A dual-axis motor is fixed to the bracket. A first one-way bearing is fixed to one output shaft of the dual-axis motor. The first one-way bearing is mounted on a first end face gear, and the first end face gear matches the first gear.

[0009] Preferably, the bracket is provided with a lifting structure to drive the spline shaft to slide within the inner spline tube. The lifting structure includes an internally threaded tube, which is rotatably mounted on the bracket. A reciprocating screw is threaded into the internal thread of the internally threaded tube. A connecting rod is fixedly connected to the reciprocating screw. The connecting rod is rotatably connected to the spline shaft. A second gear is fixedly connected to the internally threaded tube. A second one-way bearing is fixedly connected to the other output shaft of the dual-shaft motor. A second end face gear is mounted on the second one-way bearing. The second end face gear matches the second gear.

[0010] The present invention provides a millet demasking device, which has the following advantages: when demasking the female ears, the device reduces the amount of warm water required by means of water circulation, eliminating the need for staff to carry large amounts of warm water and reducing the workload of staff changing the water.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-4A device for removing male fertilization from millet includes a tank body 1 and a heating water tank 18. The heating water tank 18 is located below the tank body 1. A filter screen 19 is provided inside the heating water tank 18. An inlet pipe 17 and an outlet pipe 20 are provided on the heating water tank 18. Both the inlet pipe 17 and the outlet pipe 20 are connected to the tank body 1. A water pump 21 is provided on the outlet pipe 20.

[0019] When removing the male parent ear, pour warm water into tank 1 and put the male parent ear into tank 1. After soaking for a sufficient time, take out the male parent ear to complete the removal of male parent ear.

[0020] When the female parent ear is emasculated, the water pump 21 is started. Under the action of the water pump 21, the warm water in the heating water tank 18 is injected into the tank 1 through the water outlet pipe 20. The used warm water in the tank 1 enters the heating water tank 18 through the water inlet pipe 17 under the action of gravity. After being filtered by the filter screen 19 in the heating water tank 18, it is reheated to the required temperature and then injected into the tank 1 through the water outlet pipe 20, thus completing the water circulation. During this process, no new warm water needs to be added and no staff need to carry a large amount of warm water, so as to minimize the workload of staff changing the water.

[0021] like Figure 4 As shown, a perforated plate 2 is slidably fitted inside the tank 1, and an agitator 3 is fixedly attached to the perforated plate 2.

[0022] After the female parent spike is deemasculated and placed into the tank 1, it will be intercepted at the top by the perforated plate 2. The impurities attached to the female parent spike will fall into the heating water tank 18 below through the holes in the perforated plate 2 and be filtered by the filter screen 19 to prevent impurities in the water from affecting the deemasculation quality during the continuous deemasculation process.

[0023] like Figure 2-5 As shown, the tank body 1 is provided with a driving structure to drive the perforated plate 2 to rotate. The driving structure includes a bracket 5, which is fixed to the tank body 1. An inner spline tube 9 is slidably fitted on the bracket 5. A spline shaft 4 is slidably fitted inside the inner spline tube 9. The bottom of the spline shaft 4 is fixed to the perforated plate 2. A first gear 10 is fixed to the inner spline tube 9. A dual-axis motor 6 is fixed to the bracket 5. A first one-way bearing 8 is fixed to one output shaft of the dual-axis motor 6. The first one-way bearing 8 is mounted on a first end face gear 7. The first end face gear 7 is matched with the first gear 10.

[0024] After the female parent spike is placed into the tank 1, the dual-shaft motor 6 is started. The dual-shaft motor 6 drives the first end face gear 7 to rotate through the first one-way bearing 8. The rotation of the first end face gear 7 drives the first gear 10 to rotate. The rotation of the first gear 10 drives the inner spline tube 9 to rotate. The rotation of the inner spline tube 9 drives the spline shaft 4 to rotate. The rotation of the spline shaft 4 drives the perforated plate 2 and the stirring paddle 3 to rotate, stirring the female parent spike in the tank 1, so that the stamens in the female parent spike can fully contact the warm water in the tank 1, thereby ensuring the quality of emasculation.

[0025] like Figure 2-5 As shown, the bracket 5 is equipped with a lifting structure to drive the spline shaft 4 to slide inside the inner spline tube 9. The lifting structure includes an internally threaded tube 14, which is rotatably mounted on the bracket 5. The internally threaded tube 14 is internally threaded with a reciprocating screw 16. A connecting rod 11 is fixedly connected to the reciprocating screw 16 and is rotatably connected to the spline shaft 4. A second gear 15 is fixedly connected to the internally threaded tube 14. A second one-way bearing 13 is fixedly connected to the other output shaft of the dual-axis motor 6. A second end face gear 12 is mounted on the second one-way bearing 13 and matches the second gear 15.

[0026] The dual-axis motor 6 is reversed. The reverse rotation of the dual-axis motor 6 will drive the second end face gear 12 to rotate through the second one-way bearing 13. The rotation of the second end face gear 12 will drive the second gear 15 to rotate. The rotation of the second gear 15 will drive the internal thread tube 14 to rotate. The rotation of the internal thread tube 14 will drive the reciprocating screw 16 to perform linear reciprocating motion along the axial direction. This will cause the reciprocating screw 16 to drive the connecting rod 11 to perform lifting and lowering motion. The connecting rod 11 will drive the spline shaft 4 to perform lifting and lowering motion within the internal spline tube 9.

[0027] When the emasculated female ear is removed from the tank 1, the spline shaft 4 is raised. The rise of the spline shaft 4 causes the perforated plate 2 to move upward in the tank 1. The emasculated female ear in the tank 1 will be carried out of the tank 1 by the perforated plate 2 to complete the discharge.

[0028] After the mother ear is removed from the tank 1, the spline shaft 4 is lowered. The lowering of the spline shaft 4 causes the perforated plate 2 to move down inside the tank 1, thereby completing the resetting of the perforated plate 2.

[0029] Workflow:

[0030] When removing the male parent ear, pour warm water into tank 1 and put the female parent ear into tank 1.

[0031] The dual-shaft motor 6 is started. The dual-shaft motor 6 drives the first end face gear 7 to rotate through the first one-way bearing 8. The rotation of the first end face gear 7 drives the first gear 10 to rotate. The rotation of the first gear 10 drives the inner spline tube 9 to rotate. The rotation of the inner spline tube 9 drives the spline shaft 4 to rotate. The rotation of the spline shaft 4 drives the perforated plate 2 and the stirring paddle 3 to rotate, stirring the female spike in the tank 1, so that the stamens in the female spike can fully contact the warm water in the tank 1, thereby ensuring the quality of emasculation.

[0032] After soaking for a sufficient time, once the female spikelet has been demasked, the dual-shaft motor 6 is reversed. The reverse rotation of the dual-shaft motor 6 drives the second end face gear 12 to rotate via the second one-way bearing 13. The rotation of the second end face gear 12 drives the second gear 15 to rotate. The rotation of the second gear 15 drives the internal threaded tube 14 to rotate. The rotation of the internal threaded tube 14 drives the reciprocating screw 16 to rise. The rise of the reciprocating screw 16 drives the spline shaft 4 to rise via the connecting rod 11. The rise of the spline shaft 4 drives the perforated plate 2 to move upward within the tank 1. The demasked female spikelet is then carried out of the tank 1 by the perforated plate 2, thus completing the discharge process.

[0033] After the mother ear is removed from the tank 1, the dual-axis motor 6 is reversed. The reverse rotation of the dual-axis motor 6 will drive the second end face gear 12 to rotate through the second one-way bearing 13. The rotation of the second end face gear 12 will drive the second gear 15 to rotate. The rotation of the second gear 15 will drive the internal thread tube 14 to rotate. The rotation of the internal thread tube 14 will drive the reciprocating screw 16 to descend. The descent of the reciprocating screw 16 will drive the spline shaft 4 to descend through the connecting rod 11. The descent of the spline shaft 4 will drive the perforated plate 2 to move down in the tank 1, thereby completing the resetting of the perforated plate 2.

[0034] Next, the water pump 21 is started. Under the action of the water pump 21, the warm water in the heating water tank 18 is injected into the tank 1 through the outlet pipe 20. The used warm water in the tank 1 enters the heating water tank 18 through the inlet pipe 17 under the action of gravity. After being filtered by the filter screen 19 in the heating water tank 18, it is reheated to the required temperature and then injected into the tank 1 through the outlet pipe 20, thus completing the water circulation.

[0035] Finally, put the unemasculated female parent ears into tank 1 and repeat the above work until all female parent ears have been emasculated.

[0036] Compared to existing technologies, this device reduces the amount of warm water required when emasculating female ears by using water circulation, eliminating the need for staff to carry large amounts of warm water and reducing the workload of changing the water.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
