Description

Technical Field

[0001] The utility model relates to the technical field of agricultural sowing, in particular to an agricultural sowing machine with adjustable fertilizer application amount. Background Art

[0002] In the field of agricultural planting technology, multiple steps are designed, including seed cultivation, sowing, fertilization and management after sowing, etc., among which seed sowing requires the use of a seeder.

[0003] The Chinese utility model patent with the authorization announcement number "CN216392049U" is specifically "a fertilizer seeder with adjustable fertilizer amount". It adjusts the fertilizer amount by changing the outer diameter of the driven disc and then adjusting the speed ratio between the driving pulley and the driven disc.

[0004] However, the driven disk it uses is composed of a plurality of driven belt grooves that can be extended and retracted outward. After the driven belt grooves adjust the extension amount, although the outer diameter of the driven disk formed as a whole changes, it cannot be completely fitted when in contact with the transmission belt, and there are problems of unstable transmission and slipping due to the small contact area. More importantly, it stirs the fertilizer by setting a motor and transports the stirred fertilizer at the same time, which not only increases the weight of the motor and the supporting power supply, but also increases the weight of the entire seeder, making it difficult to push, and it is not easy to achieve long-term continuous sowing due to power endurance issues. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the utility model provides an agricultural seeder with adjustable fertilizer application amount, which can effectively solve the problems raised in the background technology.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The utility model provides an agricultural seeder with adjustable fertilizer application amount, comprising a storage box and a fixing seat fixedly installed on both sides of the storage box, wherein a plowing wheel is rotatably installed on one side of the fixing seat away from the storage box, a transmission component comprises a first transmission wheel rotatably arranged in the fixing seat and fixedly connected to the center position of a circle on one side of the corresponding plowing wheel, a second transmission wheel transmission-connected to the first transmission wheel, and a fourth transmission wheel transmission-connected to the second transmission wheel, a stirring component comprises a stirring rod which penetrates the storage box and has two ends respectively extending into the corresponding fixing seat and fixedly connected to the corresponding fourth transmission wheel, an outer rod wall of the stirring rod is fixedly sleeved with a stirring shaft sleeve which is rotatably arranged at a feeding opening of the storage box, a discharging barrel is arranged at the bottom of the storage box, and the outer barrel wall is fitted with the lower bottom of the storage box, an inner barrel cavity of the discharging barrel penetrates the outer barrel wall and is provided with an arc-shaped inserting cavity, two opposite inner chamber walls of the arc-shaped inserting cavity are respectively provided with a plurality of first feeding and discharging holes corresponding to the inner arc wall and the outer arc wall of the discharging barrel, an arc-shaped inserting plate is slidably installed in the arc-shaped inserting cavity, and a plurality of second feeding and discharging holes which are opposite to the positions of the corresponding first feeding and discharging holes are penetrated and opened on the arc-shaped inserting plate.

[0008] Furthermore, a first transmission belt is wrapped around the first transmission wheel and the second transmission wheel.

[0009] Furthermore, a third transmission wheel is fixedly mounted on one side of the second transmission wheel, and a second transmission belt is wrapped around and sleeved between the third transmission wheel and the fourth transmission wheel.

[0010] Furthermore, an armrest is fixedly mounted on the outer side wall of the storage box, and a support base is vertically fixedly mounted on the bottom end of the armrest.

[0011] Furthermore, one end of the arc-shaped insert plate extends through and reaches the end of the discharge barrel, and is fixedly provided with a push-pull handle.

[0012] Furthermore, a fastening screw is threadedly installed on the outer wall of the discharge cylinder, and the screw head thread of the fastening screw extends through the arc-shaped insertion cavity and is pressed and abutted against the arc-shaped insertion plate.

[0013] Compared with the known prior art, the technical solution provided by the utility model has the following beneficial effects:

[0014] 1. The movement of the tiller wheel is synchronized with the mixing and discharging of the fertilizer through the transmission component. That is, the movement of the tiller wheel drives the mixing shaft sleeve in the storage box to rotate, thereby mixing the waste in the storage box to prevent condensation from affecting the discharge, and at the same time drives the discharge barrel to rotate. When the inlet and discharge holes on the discharge barrel rotate to a position corresponding to the discharge port at the bottom of the storage box, the fertilizer automatically passes through the inlet and discharge holes due to gravity and falls into the discharge barrel. As the discharge barrel continues to rotate, the fertilizer in the discharge barrel is discharged from the inlet and discharge holes due to gravity, realizing continuous fertilization. The entire device does not use a motor and a supporting power supply, which reduces the weight and is easy to push, and does not cause continuous sowing to be impossible due to battery life problems;

[0015] 2. An arc-shaped insert cavity is provided between the inner cylinder wall and the outer cylinder wall of the discharge cylinder, and a plurality of first inlet and discharge holes with opposite positions are provided through the contact position between the arc-shaped insert cavity and the inner cylinder wall and the outer cylinder wall. At the same time, an arc-shaped insert plate is inserted into the arc-shaped insert cavity, and a plurality of second inlet and discharge holes are provided on the arc-shaped insert plate. By adjusting the specific position of the arc-shaped insert plate inserted into the arc-shaped insert cavity, the inlet and discharge diameter of the discharge cylinder can be adjusted, and the amount of fertilizer applied in the discharge cylinder can also be adjusted.

The stirring component includes a stirring rod 21 that penetrates the storage box 2 and has two ends respectively extending into the corresponding fixed seat 1 and fixedly connected to the corresponding fourth transmission wheel 16. The outer rod wall of the stirring rod 21 is fixedly sleeved with a rotationally set The stirring sleeve 22 at the discharge port of the storage box 2 has a plurality of laterally distributed stirring shaft strips on its surface. The discharge barrel 3 is arranged at the bottom of the storage box 2, and the outer barrel wall fits with the lower bottom of the storage box 2 to prevent leakage of seeds and fertilizers. The two ends of the discharge barrel 3 are fixedly connected to the center position of the circle on one side of the corresponding second transmission wheel 13. The inner barrel cavity of the discharge barrel 3 penetrates through the outer barrel wall to open an arc-shaped insertion cavity 31. The two opposite inner cavity walls of the arc-shaped insertion cavity 31 are respectively provided with a plurality of first feed and discharge holes 32 corresponding to the inner arc wall and the outer arc wall of the discharge barrel 3. An arc-shaped plug plate 33 is slidably installed in the arc-shaped plug cavity 31. The arc-shaped plug plate 33 is penetrated by a plurality of second feed and discharge holes 34 corresponding to the positions of the corresponding first feed and discharge holes 32. The holes where the first feed and discharge holes 32 and the second feed and discharge holes 34 overlap are effective feed and discharge holes. Example

[0025] Reference Figure 1-4, which is the second embodiment of the utility model. The embodiment is different from the first embodiment in that: a first transmission belt 14 is wrapped around the first transmission wheel 12 and the second transmission wheel 13, a third transmission wheel 15 is fixedly installed on one side of the second transmission wheel 13, and a second transmission belt 17 is wrapped around the third transmission wheel 15 and the fourth transmission wheel 16. An armrest 23 is fixedly installed on the outer wall of the storage box 2, which is convenient for pushing and pulling the entire seeder. A support seat 24 is vertically fixedly installed at the bottom end of the armrest 23, which is convenient for supporting the entire seeder. One end of the arc-shaped plug plate 33 extends through and extends to the end of the discharge barrel 3, and a push-pull handle 35 is fixedly installed, which is convenient for pushing and pulling the sliding arc-shaped plug plate 33. A fastening screw 36 is threadedly installed on the outer wall of the discharge barrel 3, and the nail head thread of the fastening screw 36 extends through and extends into the arc-shaped insertion cavity 31, and squeezes and conflicts with the arc-shaped plug plate 33, so as to fix the arc-shaped plug plate 33 after the adjusted position.

[0026] The remaining structures are the same as those of Example 1.

[0027] The workflow of this utility model is as follows:

[0028] First, the seeds and fertilizers with calculated proportions are put into the storage box 2 at the same time, and the whole seeder is pushed to move by the handrail 23, so that the tilling wheel 11 is forced to rotate, thereby driving the first transmission wheel 12 to rotate, and the second transmission wheel 13 is driven to rotate by the first transmission belt 14, thereby driving the third transmission wheel 15 to rotate, and the fourth transmission wheel 16 is driven to rotate by the second transmission belt 17. Since a stirring rod 21 is connected between the two fourth transmission wheels 16, the stirring rod 21 will be connected to the stirring shaft sleeve 22 located at the discharge port of the storage box 2 to rotate, so as to stir and disperse the fertilizer and seeds to avoid condensation and agglomeration, which affects the discharge of the materials;

[0029] Secondly, since the two ends of the discharge barrel 3 are fixedly connected to the center position of the circle on one side of the corresponding second transmission wheel 13, the discharge barrel 3 will also be driven to rotate. When the discharge barrel 3 rotates to the point where the effective feed and discharge hole formed by the first feed and discharge holes 32 and the second feed and discharge holes 34 are opposite to the discharge port of the storage box 2, the fertilizer and seeds pass through the effective feed and discharge holes due to gravity and fall into the discharge barrel 3. As the discharge barrel 3 continues to rotate, the effective feed and discharge holes will continue to rotate. At this time, the fertilizer and seeds in the discharge barrel 3 move along the inner wall of the discharge barrel 3 due to gravity. When they roll down to the position of the effective discharge hole, they are discharged through the effective discharge hole, thereby realizing the synchronous discharge of seeds and fertilizers.

[0030] Finally, when the discharge amount of seeds and fertilizers needs to be adjusted, the fastening screws 36 are loosened and the arc-shaped insert plate 33 is pushed into the position in the arc-shaped insert cavity 31 to adjust the aperture of the effective feed and discharge hole, so that more or less fertilizers and seeds can be obtained from the discharge port of the storage box 2, and more or less fertilizers and seeds can be discharged through the effective feed and discharge hole.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
