Description

Technical Field

[0001] The utility model relates to the technical field of rice throwing machines, in particular to a growth fertilization device for rice seedlings thrown by a rice wind-driven high-speed throwing machine. Background Art

[0002] A rice throwing machine is a machine that plants rice seedlings in a paddy field by throwing them. According to the power acting on the seedlings, it is divided into mechanical centrifugal type and air flow type. The former consists of a power machine, a transmission mechanism, a seedling box, a feeding hopper, a throwing cone disk with a seedling guiding rail, etc. During operation, the soil-bearing seedlings are fed from the feeding hopper to the high-speed rotating throwing cone disk, and under the action of centrifugal force, the seedlings are thrown into the air and freely fall into the paddy field. The latter consists of a power machine, a blower, a seedling box, a flow stabilizer, a guide plate, a guide groove, a spray pipe, etc. During operation, the high-speed air flow generated by the blower is ejected through the spray pipe, and the seedlings fed into the guide groove are thrown into the field.

[0003] Chinese invention patent with the publication number of CN117178706A discloses an intelligent rice throwing machine capable of fertilizing and spraying pesticides simultaneously and its working method, which relates to the technical field of rice throwing machines, and includes a machine shell, a suspension bracket, a rice seedling storage and feeding mechanism, a fertilizer storage and feeding mechanism, a conveying mechanism, a throwing mechanism, a pesticide spraying mechanism and a driving mechanism. In this invention, the rice seedling storage and feeding mechanism, the fertilizer storage and feeding mechanism and the conveying mechanism operate under the drive of the driving mechanism, and can complete the automatic feeding and conveying of rice seedlings and fertilizers. Through the throwing mechanism, rice seedlings can be automatically thrown into the field and fertilized simultaneously.

[0004] While automatically throwing rice seedlings, this invention can also perform automatic fertilization and pesticide spraying operations, without the need for agricultural personnel to operate step by step, improving the overall labor efficiency and saving time and effort. However, in this invention, the fertilizer storage and feeding mechanism for fertilization, that is, the fertilization device, can only achieve fixed-dose fertilizer feeding by relying on the feeding groove outside the feeding roller, and cannot adjust the fertilizer amount. At the same time, the fertilizer falls on the conveying mechanism and is thrown out synchronously with the seedlings on it, which easily causes the seedlings to directly contact the fertilizer, thereby affecting growth. Finally, due to the different weights and volumes of fertilizers and seedlings, the wind forces required to blow them to a specified distance are also different. Therefore, when the fertilizers and seedlings are simultaneously placed on the conveying mechanism and blown out, the blowing of fertilizers and the blowing of seedlings are not separated, and this method easily causes a large error in the blowing distances of fertilizers and seedlings, resulting in insufficient fertilization and affecting the fertilization and sowing effects. Content of the Utility Model

[0005] Aiming at the deficiencies in the above background art, the utility model proposes a growth fertilization device for rice seedlings thrown by a rice wind-driven high-speed throwing machine, which solves the problem of insufficient fertilization caused by the need to control the blowing of fertilizers and seedlings together in the fertilization device of the existing throwing machine.

The outer side of the baffle is connected with an adjusting handle, and the adjusting handle can drive the baffle to rotate into the arc-shaped material discharge port.

[0009] Preferably, a fertilizer amount scale corresponding to the adjusting handle is provided on the baffle plate.

[0010] Preferably, the material discharging component includes a material discharging groove connected to the bottom of the baffle plate. A grooved wheel is provided on the material discharging groove. The wheel shaft of the grooved wheel is in transmission connection with a driver provided outside the material discharging groove.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figure 1 、 2 shown, in Embodiment 1, a fertilizer application device for the growth of rice seedlings transplanted by a wind-blown high-speed rice transplanter includes a support frame 1 for connecting to the transplanter. In this embodiment, the support frame 1 is a profile frame, and the support frame is connected to the transplanter body by bolts, providing a connection and support foundation for the entire fertilizer application device. A fertilizer box 2 is provided on the support frame 1, a blanking port 3 is provided at the bottom of the fertilizer box 2, and a fertilizer amount adjusting mechanism 4 is provided on the blanking port 3. The bottom of the fertilizer amount adjusting mechanism 4 is connected to a blanking component 5. During the fertilizer application process, through the cooperation of the fertilizer amount adjusting mechanism and the blanking component, the amount and speed of blanking can be controlled to achieve precise blanking. The discharge end of the blanking component 5 is connected to an air duct 6, and the air duct 6 is connected to a fan. By setting the air duct and the fan, the applied fertilizer can be blown out separately without being blown out together with the seedlings, achieving more precise fertilizer application control.

[0023] In this embodiment, the fertilizer box 2 includes a box body with an open top and several ear seats provided on the side walls. The ear seats are connected to the support frame by bolts. A pair of hoppers 8 are provided at the bottom of the box body, and the discharge port 3 is located at the bottom of the hopper 8. Correspondingly, two fertilizer amount adjusting mechanisms, two discharging assemblies, and two air ducts connected to the discharge port are provided. The two air ducts can share the same blower or be respectively connected to a blower. As an alternative solution, a top cover is provided on the top of the box body, which can achieve the effects of dust prevention and splash prevention.

[0024] During actual use, fertilizers are added into the fertilizer box. Along with the blowing and throwing of the seedlings, the blower is started synchronously. At the same time, the fertilizers in the fertilizer box enter the discharging assembly through the discharge port and the fertilizer amount adjusting assembly. The discharging assembly realizes the discharging of fertilizers. The fertilizers discharged by the discharging assembly enter the air duct and are blown away by the wind blown by the blower. This fertilizing device independently sets the blower and the air duct for blowing fertilizers, thus avoiding being blown out together with the seedlings in the case of sharing the blower in the prior art. The blowing force and distance of the fertilizers can be controlled, thereby improving the fertilizing effect. At the same time, this fertilizing device can also flexibly control the discharging rate and the discharging amount, and has stronger reliability and controllability.

[0025] Embodiment 2, on the basis of Embodiment 1, as Figure 3 shown, the fertilizer amount adjusting mechanism 4 includes a retaining plate 9 fixedly provided at the bottom of the discharge port 3. An arc-shaped discharge opening 10 is formed on the retaining plate 9. A sector-shaped groove 11 is formed inside the retaining plate 9, and the sector-shaped groove 11 is communicated with the arc-shaped discharge opening 10. A retaining piece 12 is rotatably provided in the sector-shaped groove 11. The outer side of the retaining piece 12 is connected with an adjusting handle 13, and the adjusting handle 13 can drive the retaining piece 12 to rotate into the arc-shaped discharge opening 10. During use, the adjusting handle is used to drive the retaining piece to rotate, so as to drive the retaining piece to enter the arc-shaped discharge opening, and a certain amount of the arc-shaped discharge opening is blocked, thereby reducing or increasing the size of the fertilizer discharging channel and realizing the adjustment of the discharging speed.

[0026] Specifically, a rotating shaft is fixedly provided at the center of the sector-shaped groove of the retaining plate. The rotating shaft coincides with the axis of the arc-shaped discharge opening. One end of the retaining piece 12 is hinged to the rotating shaft. The retaining piece is provided with an inserting portion that matches the size and shape of the arc-shaped discharge opening. When the adjusting handle at the outer end is toggled, the inserting portion of the retaining piece is driven to enter the arc-shaped discharge opening, thereby realizing the reduction of the diameter of the discharge opening and the adjustment of the discharging rate.

[0027] As a further implementation manner, the retaining plate 9 is provided with fertilizer amount scales corresponding to the adjusting handle 13, so that when adjusting the fertilizer discharging speed, the degree to which the retaining piece enters the arc-shaped discharge opening and the opening degree of the arc-shaped discharge opening can be determined with reference to the corresponding fertilizer amount scales.

[0028] Embodiment 3, on the basis of Embodiment 2, as Figure 4 、 5As shown, the feeding assembly 5 includes a feeding chute 14 connected to the bottom of the baffle plate 9, and a groove wheel 15 is provided on the feeding chute 14. The axle of the groove wheel 15 is connected to a driver 16 provided outside the feeding chute 14, and the driver can drive the groove wheel to rotate during fertilization. In this embodiment, the feeding chute is a circular groove, the bottom of the circular groove is closed by a bottom plate, and a fertilizer discharge port 17 is provided on the bottom plate of the feeding chute, and the fertilizer discharge port 17 is connected to the air duct 6. In addition, a through groove 18 is provided on the groove wheel 15. In the present embodiment, two through grooves are symmetrically provided and penetrate the groove wheel in the axial direction, and the fertilizer discharge port 17 is staggered with the arc-shaped discharge port 10. When the through groove of the groove wheel rotates to correspond to the arc-shaped discharge port, the fertilizer enters the through groove through the arc-shaped discharge port and is blocked by the bottom plate. As the groove wheel rotates, the fertilizer in the through groove is carried and moved until it corresponds to the fertilizer discharge port and falls into the fertilizer discharge port. During this process, the other through groove corresponds to the arc-shaped discharge port and continues to carry new fertilizer to enter.

[0029] In this embodiment, the axles of the two groove wheels 15 are connected to the driver 16 through a belt transmission pair. The driver 16 is a driving motor, so that the driving motor can synchronously drive the two groove wheels to rotate synchronously. By controlling the speed of the driving motor, the speed of the groove wheel can be controlled, thereby controlling the time when the waste falls into the through slot, and then controlling the amount of fertilizer discharged.

[0030] As a further embodiment, the wind tube 6 is a rectangular wind tube, the top of which is connected to the fertilizer discharge port 17 of the feeding assembly 5. When the fertilizer enters the fertilizer discharge port, it falls into the rectangular wind tube under the action of gravity. The front end of the rectangular wind tube is open, and the tail is connected to an air pipe, which is connected to a fan. The fan blows air to the rectangular wind tube through the air pipe, thereby blowing the fertilizer inside into the rice field. By individually controlling the wind speed blown by the fan, the distance the fertilizer is blown out can be accurately controlled to achieve precise fertilization.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
