[0033] Fertilization can provide nutrients for crops, and is also an agricultural technical measure to maintain and improve soil fertility and crop yields. It can be said that soil fertilization is an indispensable link in agricultural production. In my country, crop fertilization mainly relies on manual labor, which is labor-intensive and has high labor costs. Especially in hilly and mountainous areas and agricultural greenhouses, the land is small and can only be spread manually. The uniformity of fertilizer spreading and fertilizer utilization efficiency are still low; and direct contact with fertilizer by hand is also harmful. At present, there are some automatic fertilization devices in agricultural production, such as water-fertilizer integrated machines, electric fertilizer spreaders with automatic adjustable spreading range and spreading amount, etc. Water-fertilizer integrated machines are widely used in facility agriculture. They are generally used for soluble fertilizers. They are irrigated to the roots of crops together with irrigation water. They are not suitable for solid fertilizers or fertilizers that are difficult to dissolve. Electric fertilizer spreaders with automatic adjustable spreading range and spreading amount are mainly used in large fields and driven by tractors. However, this large electric fertilizer spreader with adjustable spreading range and spreading amount is mainly suitable for use on large farmland and is not suitable for small plots such as greenhouses, hilly and mountainous areas. In addition, there are also some small backpack and hand-push electric fertilizer spreaders with adjustable spreading range and spreading amount in production, which are mainly used to assist manual fertilizer spreading, but the amount and uniformity of fertilizer spreading cannot be controlled, the fertilizer spreading is uneven and the fertilizer is wasted.

[0034] Figure 1 It is a schematic diagram of the overall structure of an electric fertilizer spreading device with adjustable spreading range and spreading amount provided by an embodiment of the utility model.

[0035] See also Figure 1 The utility model provides an electric fertilizer spreading device with adjustable spreading range and spreading amount, and the electric fertilizer spreading device with adjustable spreading range and spreading amount includes a vehicle body 100, a storage barrel 200, a fertilizer spreading disc 300 and a driving assembly 400, such as Figure 1As shown, the vehicle body 100 in the embodiment of the utility model adopts the structure of a trolley, which is simple and compact, and is conducive to working in a narrow environment. The vehicle body 100 includes structures such as a support frame, a handle and a walking device 110. The storage barrel 200 is arranged on the support frame, and the storage barrel 200 includes a feed port 210 and a discharge port 220. The feed port 210 is arranged above the storage barrel 200, and the discharge port 220 is arranged below the storage barrel 200. In this way, the fertilizer can be easily in and out of the storage barrel 200 under the influence of its own weight, eliminating other complex mechanisms for loading and unloading, which is conducive to the miniaturization of the vehicle body 100. The storage barrel 200 can be selected as a plastic material or a stainless steel material, which can improve the corrosion resistance of the storage barrel 200. Specifically, it can be adaptively selected according to actual conditions.

[0036] The fertilizer spreading disc 300 is also arranged on the support frame, and the fertilizer spreading disc 300 is arranged directly below the discharge port 220, so that the fertilizer coming out of the discharge port 220 can directly fall on the fertilizer spreading disc 300 for spreading. The driving assembly 400 is also arranged on the support frame, one end of the driving assembly 400 is connected to the walking device 110, and the other end is connected to the fertilizer spreading disc 300. The driving assembly 400 is used to drive the walking device 110 to rotate to assist the electric fertilizer spreading device with adjustable spreading range and spreading amount to move forward. At the same time, the driving assembly 400 is also used to drive the fertilizer spreading disc 300 to rotate to achieve the spreading of fertilizer.

[0037] See also Figure 1 It can be understood that the electric fertilizer spreading device with adjustable spreading range and spreading amount provided by the embodiment of the utility model drives the walking device 110 to rotate by setting a driving assembly 400, which can save manpower and improve the travel efficiency of the electric fertilizer spreading device with adjustable spreading range and spreading amount; in addition, the driving assembly 400 drives the rotation of the fertilizer spreading disc 300, so that the fertilizer spreading disc 300 and the walking device 110 can share a power source, which can make the driving assembly 400 have a multi-purpose effect and improve the practicality of the driving assembly 400. Compared with the prior art, the electric fertilizer spreading device with adjustable spreading range and spreading amount provided by the embodiment of the utility model drives the walking device 110 through the driving assembly 400, eliminating the need for manpower. During use, the user only needs to play a guiding role, which greatly reduces the labor intensity and improves the fertilization efficiency.

[0038] Continue reading Figure 1In an optional embodiment of the utility model, the driving assembly 400 includes a motor 410 and a transmission gear 420. The motor 410 includes a first output end and a second output end. The first output end is arranged at the upper end of the motor 410 shown, and the second output end is arranged at the lower end of the motor 410. The fertilizer spreading disc 300 is connected to the first output end and keeps synchronous rotation with the first output end. In an optional embodiment of the utility model, a reduction box can also be arranged between the first output end and the fertilizer spreading disc 300. Specifically, it can be adaptively arranged according to actual conditions.

[0039] The transmission gear 420 is meshed with the second output end of the motor 410, and the transmission gear 420 is suitable for driving the traveling device 110 to rotate under the drive of the second output end. It can be understood that the speed of the motor 410 is stable and easy to adjust, and the motor 410 drives the fertilizer spreading disc 300 and the traveling device 110 to work, which is simple and efficient. In addition, the motor 410 is easy to obtain, low in cost, and mature in technology, which can facilitate the production of an electric fertilizer spreading device with adjustable spreading range and spreading amount.

[0040] Continue reading Figure 1 In an optional embodiment of the utility model, the walking device 110 includes a first walking wheel 111, a second walking wheel 112 and a rotating shaft 113. The first walking wheel 111 is arranged on one side of the rotating shaft 113, and the second walking wheel 112 is arranged on the other side of the rotating shaft 113. The rotating shaft 113 passes through the transmission gear 420 and is fixedly connected to the transmission gear 420. It can be understood that when the transmission gear 420 rotates under the drive of the second output end, the transmission gear 420 can synchronously drive the rotating shaft 113, the first walking wheel 111 and the second walking wheel 112 to rotate synchronously to realize the movement of the walking device 110.

[0041] Continue reading Figure 1 In an optional embodiment of the utility model, the electric fertilizer spreading device with adjustable spreading range and spreading amount further includes a controller 500, which is arranged at the handle of the vehicle body 100, and the controller 500 is electrically connected to the motor 410. In this way, during use, the rotation speed of the motor 410 can be directly controlled by the controller 500, thereby realizing the control of the travel speed of the walking device 110 and the control of the rotation and spreading speed of the fertilizer spreading disc 300.

[0042] The following is an experiment on the effect of the travel speed on the fertilizer spreading amount per unit area in the embodiment of the utility model. The experiment set up four treatments of the electric fertilizer spreading device with adjustable spreading range and spreading amount, the manual forward speed was 0.5m / s, 1.0m / s, 1.5m / s, and 2.0m / s, the speed of the fertilizer spreading disc 300 was set to 200r / min, the opening ratio of the discharge port 220 was fully open, and 3 repetitions were set in the open air and the greenhouse respectively. The fertilizer spreading amount per unit area was tested, and the average value of the 3 repetitions was taken, as shown in Table 1.

[0043] Table 1 Effect of different travel speeds on fertilizer spreading rate per unit area

[0044]

[0045] The data results show that the travel speed of the electric fertilizer spreader with adjustable spreading range and spreading amount is inversely proportional to the amount of fertilizer spread per unit area. The faster the travel speed, the smaller the amount of fertilizer spread per unit area. Under the condition that the size of the discharge port 220 is fixed, if you want to increase the total amount of fertilizer applied, you have to reduce the travel speed of the electric fertilizer spreader with adjustable spreading range and spreading amount.

[0046] Figure 2 It is a schematic diagram of the opening and closing member provided by the embodiment of the utility model in one state; Figure 3 It is a schematic diagram of the opening and closing member provided by an embodiment of the utility model in another state.

[0047] See also Figures 1 to 3 In an optional embodiment of the utility model, the storage barrel 200 also includes an opening and closing piece 230, which is arranged at the discharge port 220, and the opening and closing piece 230 is electrically connected to the controller 500. The opening and closing piece 230 is used to adjust the opening and closing size of the discharge port 220. In this way, during use, the opening and closing size of the discharge port 220 can be adjusted to achieve precise control of the fertilizer output.

[0048] Specifically, the opening and closing piece 230 can be a rotating thin sheet arranged at the discharge port 220. When the discharge port 220 is in a closed state, the opening and closing piece 230 can cover the discharge port 220 to achieve sealing of the discharge port 220. When the discharge port 220 is in an open state, the opening and closing piece 230 can be rotated to another place. Specifically, it can be adaptively set according to actual conditions.

[0049] The following is an experiment on the effect of the opening and closing degree of the discharge port 220 on the fertilizer spreading amount and uniformity in the embodiment of the utility model. In this embodiment, three discharge ports 220 are set as an example. The experiment sets four treatments for adjusting the size of the fertilizer discharge port 220, which are set to 1 / 3, 1 / 2, 2 / 3, and fully open respectively. The manual forward speed of the fertilizer spreader is 1.5m / s, and the speed of the fertilizer spreader 300 is set to 200r / min. The diameter of a single discharge port 220 is 50mm. Three repetitions are set in the open air and the greenhouse respectively. The fertilizer spreading amount and uniformity under different discharge port 220 sizes are tested respectively, and the results are averaged.

[0050] The experimental records are as follows:

[0051] Table 2 Effect of different discharge port opening ratios on the amount and uniformity of granular fertilizer spread

[0052]

[0053] Table 3 Effect of different discharge port opening ratios on the amount and uniformity of powdered fertilizer spread

[0054]

[0055] It can be seen from the above data that the opening and closing size of the discharge port 220 is proportional to the amount of fertilizer spread. The larger the discharge port 220 is, the greater the amount of fertilizer spread is. Different sizes of the discharge port 220 do not affect the uniformity of fertilizer spread.

[0056] Continue reading Figure 1 In an optional embodiment of the utility model, the driving component 400 also includes a battery 600, which is arranged on the vehicle body 100 and is electrically connected to the motor 410. The battery 600 is used to provide electrical energy for the motor 410. It can be understood that the battery 600 is easy to replenish energy and the energy supply is smooth and smooth, which can improve the stability of the motor 410 and help to stabilize and last the rotation speed of the motor 410.

[0057] Figure 4 It is a structural schematic diagram of a fertilizer spreading plate provided in an embodiment of the utility model.

[0058] See also Figure 1 and Figure 4 The fertilizer spreading plate 300 includes a plate body 310, a baffle plate 320 and a fertilizer pushing plate. The baffle plate 320 and the fertilizer pushing plate are separated only on the upper surface of the plate body 310. The baffle plate 320 and the fertilizer pushing plate can be adaptively set according to the demand for fertilizer spreading uniformity. In the embodiment of the utility model, five baffle plates 320 and five fertilizer pushing plates 330 are set as an example. As shown in the figure, the five baffle plates 320 and the five fertilizer pushing plates 330 can evenly divide the fertilizer spreading plate 300 into 10 equal parts, so as to ensure that the fertilizer falling on the fertilizer spreading plate 300 is evenly distributed. After the fertilizer particles fall on the fertilizer spreading plate 300, during the rotation process of the fertilizer spreading plate 300, the fertilizer particles encounter the rotating fertilizer pushing plates 330, and will be hit and thrown out at a certain speed, thereby realizing the fertilizer spreading process.

[0059] In an optional embodiment of the utility model, the rotation speed of the disk 310 is a, wherein the value range of a is 100 to 540 r / min. For example, the rotation speed of the disk 310 can be set to 100 r / min, 200 r / min, 300 r / min, 400 r / min, 500 r / min or 540 r / min. The following is an experiment on the influence of the rotation speed of the disk 310 on the fertilizer spreading radius in the embodiment of the utility model. The experiment sets 10 treatments of the rotation speed of the disk 310, the rotation speed range is 100 to 540 r / min, the manual forward speed of the fertilizer spreader is 1.5 m / s, and the opening ratio of the discharge port 220 is fully open. Three repetitions are set in the open air and the greenhouse respectively, and the fertilizer spreading radius under different rotation speeds of the disk 310 is tested. The results are averaged, as shown in Table 3.

[0060] Table 4 Effect of different disc speeds on fertilizer spreading radius

[0061]

[0062] The data results show that the rotation speed of the disc 310 is proportional to the fertilizer spreading radius. The faster the rotation speed, the larger the fertilizer spreading radius. Referring to the above data and related information, it can be concluded that the rotation speed of the disc 310 directly affects the fertilizer spreading range. Under the same other conditions, the faster the rotation speed of the disc 310, the larger the fertilizer spreading radius. The rotation speed of 540r / min is the limit rotation speed of the disc 310. The fertilizer spreading radius does not change much beyond 540r / min. If the rotation speed of the disc 310 is too high, the fertilizer with a relatively light weight is easy to change its trajectory, resulting in fertilizer waste and uneven fertilizer spreading; if the rotation speed is too slow, the fertilizer spreading radius is too small; therefore, the rotation speed of the disc 310 ranges from 100 to 540r / min. In addition, the diameter of the disc 310 generally ranges from 100 to 350mm. The test diameter is 250mm and the height from the ground is 400mm.

[0063] Continue reading Figure 1 In an optional embodiment of the utility model, the cross-sectional area of ​​the storage barrel 200 gradually decreases along the direction from the feed port 210 to the discharge port 220. Specifically, the barrel can be selected as a conical barrel, such as a cylindrical body in the shape of a cone or a quadrangular pyramid. Specifically, it can be adaptively selected according to actual conditions. It can be understood that the side wall of the cone has a certain inclination, which facilitates the smooth fall of fertilizer and improves the efficiency of fertilizer spreading.

[0064] Figure 5 The utility model is provided in the embodiment of the present invention, which is a schematic diagram of the working process of the electric fertilizer spreading device with adjustable spreading range and spreading amount.

[0065] When the electric fertilizer spreading device with adjustable spreading range and spreading amount is working, the fertilizer can be poured into the storage barrel 200 first, and the opening and closing size of the discharge port 220 can be adjusted to control the fertilizer output. The electric fertilizer spreading device with adjustable spreading range and spreading amount can be manually pushed to control the fertilizer spreading direction; turn on the power switch, adjust the controller 500 to make the motor 410 reach the operating speed, and at the same time, the motor 410 drives the fertilizer spreading disc 300 to rotate at a high speed. The rotating fertilizer spreading disc 300 will evenly spread the fertilizer falling from the upper discharge port 220 according to a certain radius.
