Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural planting technology, in particular to a fertilizer application device, and particularly to a high-efficiency fertilizer application device for Torreya grandis in mountainous environments. BACKGROUND

[0002] Torreya grandis is a unique and valuable dried fruit and economic tree species in China, and is widely planted in hilly and mountainous areas in Zhejiang, Fujian, and Anhui. The traditional fertilization method faces three core problems:

[0003] 1) Terrain limitations: It is difficult to achieve mechanized operation in mountainous areas with slopes, and existing fertilizer application equipment has problems such as unstable center of gravity and poor climbing ability, resulting in a fertilizer coverage rate of less than 30%;

[0004] 2) Fertilizer loss: Conventional direct manual fertilizer spreading to the ground is easily washed away by rainwater, and the nitrogen utilization rate is only 40%-45%, which is significantly lower than that in plain areas;

[0005] 3) Labor costs: Manual backpack fertilization is inefficient, requiring 2-3 workdays per mu, accounting for more than 35% of the total planting cost.

[0006] Therefore, there is an urgent need to develop a mountainous Torreya grandis fertilization device suitable for mountainous terrain, which can prevent fertilizer from being washed away by rainwater after fertilization, and has high efficiency and low planting cost, to break through the bottleneck of existing technology.

[0007] Chinese utility model patent CN 215223077 U discloses a quantitative fertilizer application device for Torreya grandis forest land, which comprises a base, a feed tank fixedly connected to the upper end of the base, a feed pipe fixedly connected to the upper end of the feed tank, a machine box fixedly connected to the upper end of the feed pipe, and a feed hopper fixedly connected to the upper end of the machine box. It also includes a quantitative assembly; the quantitative assembly is used to control the amount of fertilizer during device fertilization, and the quantitative assembly is arranged on the feed tank. The quantitative assembly includes a control panel fixedly installed on the feed tank, a display screen fixedly provided on the control panel, a control button fixedly provided at the lower end of the display screen, a processor fixedly provided in the control panel, a quantitative valve fixedly provided in the feed pipe, and an electrical connection between the display screen, the control button, the processor, and the quantitative valve. The lower end of the feed tank is fixedly connected with a discharge hose, the discharge hose passes through the base and extends to the lower end of the base, the lower end of the discharge hose is fixedly connected with a connecting plate, and the lower end of the discharge hose is fixedly connected with a discharge pipe. The discharge pipe passes through the connecting plate and extends to the lower end of the connecting plate. The device cannot be used in mountainous environments, has poor versatility, and can only dig trenches and apply fertilizer in the trenches far from the Torreya grandis trees on the side of the trees, and cannot directly act on the Torreya grandis trees, resulting in low fertilizer absorption and utilization rate.

[0052] The working principle of the present application: when fertilizing the Torreya grandis 15 planted on the uphill mountain, only need to use the control screen 11 first, and use the PLC controller 13 to transmit signals, control the first electric cylinder 5-5 and drive the vertical plate 5-1 to rotate in the clockwise direction by an angle and make the two clamping plates 5-6 keep parallel with the horizontal plane (such as Figure 13As shown, this is to enable two clamps 5-6 to clamp the torreya 15 vertically, then start the first drive motor 3-1, so that the clamps 5-6 are moved by the track wheel 2 and guided by the guide plate 5-6d, so that the two clamps 2 are squeezed apart by the torreya 15, at this time the two first compression springs 5-7 are compressed and stored energy, the clamps 5-6 move forward and until the four wheels 5-14 clamp the four corners of the torreya 15, at this time the track wheel 2 stops running, the fertilizer device stops moving and the rear stop 8 stops moving and supports, then the second drive motor 5-3 is controlled by the PLC controller 13 to run, so as to drive the mounting plate 5-2 to move down, and in turn drive the clamps 5-6 to move down, because the mountain terrain has slope, each shaft 5-11 first touches the mountain surface and makes each shaft 5-11 move through the oval rod 5-8 and compress the second compression spring 5-13 to store energy, at this time the flat plate 5-9 and the first hollow motor 5-10 are moved up together with the oval rod 5-8, so that each shaft 5-11 touches the ground according to the height of the mountain terrain, then start each first hollow motor 5-10 and drive the shaft 5-11 and the spiral digging blade 5-12 to rotate, synchronously drive the mounting plate 5-2 to move down, so that each spiral digging blade 6-7 rotates and digs down, so as to drill holes in the mountain soil layer, at the same time, the fertilizer particles in the container 6-1 slide to the first horizontally placed cylinder 6-3 through the gathering effect of the discharging disc 6-2, and the rotating spiral propelling blade 6-7 pushes the fertilizer particles to the first vertically placed cylinder 6-4, and then the rotating spiral propelling blade 6-7 in the first vertically placed cylinder 6-4 lifts the fertilizer particles, and through the rapid guidance of the first downward inclined disc 6-5, the fertilizer particles reach the first downward inclined cylinder 6-6, and then the rotating spiral propelling blade 6-7 in the first downward inclined cylinder 6-6 uniformly delivers the fertilizer particles to the discharge pipe 6-6a, and then the second hollow motor 12-2 in the fertilizer particle equal distribution device 12 rotates at equal angles four times, so as to deliver the equal parts of the fertilizer particles to each discharge pipe 12-3, so that the fertilizer particles are discharged into the dug hole through the delivery hose 7, the hollow shaft of the first hollow motor 5-10, the discharge channel 5-11a, and the discharge hole 5-11b. Then, the second drive motor 5-3 is controlled by the PLC controller 13 to start and drive the mounting plate 5-2 to reset upwards, so that when the next torreya 15 is fertilized, the above steps can be repeated, the efficiency is very high, and the fertilizer particles in the holes near the torreya 15 will not be lost in heavy rain, and the utilization rate of the fertilizer particles near the torreya 15 is high.

[0053] When the fertilization is carried out on the torreya grandis 15 planted on the downhill mountain, the fertilization mode is identical with the fertilization mode on the uphill mountain, the only difference is that the first electric cylinder 5-5 drives the vertical plate to rotate counterclockwise, so as to drive the two clamping plates 5-6 to be parallel to the horizontal plane, and then accurately clamping the torreya grandis 15, and the other operation steps are the same as the fertilization mode of the torreya grandis 15 on the uphill mountain, when the fertilization is carried out on the downhill mountain, in order to make the fertilization device more stable, the front resisting piece 9 needs to be started to resist the front moving resistance supporting (such as shown in Figure 14 The application can carry out rapid and efficient fertilization in the mountain slope environment, can greatly reduce the labor intensity of the laborer, improve the mountain torreya fertilization efficiency, improve the utilization rate of the fertilizer, greatly reduce the planting cost of the torreya, and is worth popularization and application.

[0054] Although the application has been illustrated and described with reference to the preferred embodiments, it should be understood by those skilled in the art that various changes in form and details can be made within the scope of the claims.
