Description

Technical Field

[0001] The invention relates to the field of agricultural machinery, and in particular to a multifunctional topdressing machine used in mountainous areas. Background Art

[0002] Tobacco crops are mainly used to produce various tobacco products, among which tobacco leaves are the main raw material of tobacco products. During the growth process of tobacco plants, topdressing is required to ensure the healthy growth of the plants. At the same time, topdressing of different fertilizers can promote the growth of tobacco leaves and increase yield. The tobacco leaves in the middle and late stages of tobacco plant growth are wide, and the growth of tobacco leaves will exceed the range of the planting ridges and extend to the gullies between the ridges. As a result, existing topdressing agricultural machinery will scratch the tobacco leaves when walking along the gullies, causing damage to tobacco crops and affecting yield. At the same time, the tobacco leaves in the middle and late stages are drooping, and the bottom leaves are close to the surface of the planting ridges, blocking the surface of the planting ridges around the main trunk, affecting the position of topdressing. Summary of the invention

[0003] In order to overcome the shortcomings of existing topdressing machines in the middle and late stages of tobacco growth, such as easily scratching the fallen leaves when moving between ridges to damage the crops, and the bottom leaves blocking the ridge surface, thus affecting the precise topdressing, the present invention provides a multifunctional topdressing machine for mountainous areas.

[0019] It also includes an air intake box 7; an air intake box 7 is installed at the bottom of each shovel plate 5 away from the support plate 4; five air blowing ports 51 are opened on each shovel plate 5; all the air blowing ports 51 on the same shovel plate 5 are connected to the air intake box 7 below it; an air pump is installed on the topdressing vehicle 1; the air intake box 7 is connected to the air pump through a connecting hose.

[0020] It also includes a flap 8 ; seven debris discharge openings 52 are opened on the side of the shovel plate 5 away from the supporting plate 4 ; the shovel plate 5 is connected to seven flaps 8 through a damping shaft; each flap 8 corresponds to a debris discharge opening 52 .

[0021] The side of the side guide plate 3 away from the side baffle plate 2 is configured to be rounded to prevent the side guide plate 3 from cutting off the tobacco leaves when contacting the tobacco leaves.

[0022] The fertilization pipe 12 is a telescopic pipe, which is convenient for adjusting the fertilization position.

[0023] The tires of the topdressing vehicle 1 are mountain tires, which facilitates the present invention to travel on complex road conditions such as mountains.

[0024] A filter screen is provided at the air outlet 51 to prevent debris from entering and blocking the air outlet 51 .

[0025] The shovel head 6 is made of metal, which increases its service life and improves the effect of shoveling soil.

[0026] The method of using the multifunctional topdressing machine for mountainous areas of the present invention is as follows: Before topdressing, the user adds fertilizer into the storage box 11. The storage box 11 is equipped with an electric spiral auger for discharging materials. The electric spiral auger is driven by the gasoline generator on the topdressing vehicle 1. Then the user drives the topdressing vehicle 1 so that the avoidance channel formed by all the side baffles 2, the side guide plates 3, the support plates 4 and the shovel plates 5 are aligned with a row of tobacco, and adjusts the height of the side baffles 2, the side guide plates 3, the support plates 4 and the shovel plates 5 by controlling the extension and retraction of the electric push rod 101, so that the shovel head 6 on the shovel plate 5 is 2-5 cm lower than the upper surface of the ridge where the tobacco is planted, ensuring that the shovel head 6 can shovel up some soil when moving.

[0027] Then, the fertilizer topdressing vehicle 1 is driven toward the row of tobacco, and the tires of the fertilizer topdressing vehicle 1 travel in the gullies between the tobacco planting ridges. During the process of moving forward, the side guide plates 3 first contact the wide tobacco leaves, and through the guidance of the side guide plates 3, the tobacco leaves are gathered between the two side baffles 2, and the two side baffles 2 are limited to prevent the expanded tobacco leaves on both sides from being crushed and pulled by the tires of the fertilizer topdressing vehicle 1 when the fertilizer topdressing vehicle 1 passes through the tobacco planting row, causing damage to the tobacco leaves and affecting the yield, while the main trunk of the tobacco plant passes through the avoidance channel without contacting the parts; at the same time, during the process of moving, the shovel head 6 is 2-5 cm lower than the upper surface of the tobacco planting ridge, and then the shovel head 6 can shovel up the tobacco leaves close to the ground to separate them from the ground, and at the same time, the shovel head 6 shovels up part of the soil around the tobacco plant, and as the fertilizer topdressing vehicle 1 As the fertilizer cart 1 moves, the soil and tobacco leaves move backwards to the support plate 4 and finally fall on the rear side of the support plate 4. During this process, the electric spiral auger in the storage box 11 is controlled to work, and the fertilizer is sent to the fertilizer pipe 12 on the lower side of the support plate 4 through a hose, and is sprinkled on the soil around the tobacco plants by the fertilizer pipe 12 (the discharge port of the fertilizer pipe 12 is 10-15 cm away from the tobacco plants to avoid direct contact of the fertilizer with the root system and cause fertilizer damage). At this time, the soil on the lower side of the support plate 4 has been shoveled up by the shovel head 6, and then when the topdressing vehicle 1 moves, the fertilizer pipe 12 is not hindered. At the same time, when the shoveled soil falls from the support plate 4 again, it can cover the surface of the sprinkled fertilizer, thereby accelerating the fusion of the fertilizer and the soil and avoiding the loss of the fertilizer. After the topdressing of one row of tobacco is completed, the user turns the topdressing vehicle 1, realigns the next row of tobacco, and continues the topdressing work.

[0028] Due to the changeable climate in some areas, plastic film is covered on the planting ridges for heat preservation and moisture retention during tobacco planting. At this time, it is impossible to shovel the soil by the shovel head 6 to shovel the tobacco leaves close to the surface of the planting ridge to avoid the topdressing vehicle 1. Therefore, for the planting ridges covered with plastic film, before topdressing, the user removes the shovel head 6 from the shovel plate 5 to expose the blowing port 51 on the shovel plate 5, and then connects the air intake box 7 to the air pump through the connecting pipe, and controls the electric push rod 101 to drive the side baffle 2 and its connecting parts to move upward, so that the lower side of the shovel plate 5 is 2-5 cm higher than the upper surface of the planting ridge, so that the shovel plate 5 does not touch the plastic film on the planting ridge during the movement to prevent it from being damaged; when performing topdressing, control the air pump When the shovel plate 5 contacts the tobacco leaves near the surface of the planting ridge, the air blown out of the air port 51 blows up the tobacco leaves so that they are located on the shovel plate 5 and away from the surface of the planting ridge. As the topdressing vehicle 1 moves forward, the tobacco leaves will move on the upper surface of the shovel plate 5, so that the shovel plate 5 can shovel up the tobacco leaves near the surface of the planting ridge without damaging the plastic film on the planting ridge. Therefore, the present invention can be adaptively changed according to different planting conditions and has strong practicality. It should be understood that the plastic film has been torn in advance near the main trunk to expose the ridge surface for topdressing. When fertilizing, the discharge port of the fertilizer pipe 12 is aligned with the exposed ridge surface to sprinkle the fertilizer on the planting ridge.

[0029] In addition, when the shovel head 6 is used to shovel up soil for topdressing, the shovel head 6 shields and protects the air port 51 to prevent soil from entering the air port 51 and causing blockage, thereby affecting the use.

[0030] Furthermore, when applying topdressing to tobacco on the planting ridges covered with plastic film, it is inevitable that there will be small clods of soil and other debris on the surface of the plastic film, and the lowest point of the shovel plate 5 cannot be too high from the surface of the plastic film, otherwise it will affect the effect of shoveling up the tobacco leaves close to the surface of the planting ridge. Therefore, the shovel plate 5 close to the plastic film can easily shovel up small clods of soil. As the topdressing vehicle 1 moves forward, the clods of soil will accumulate on the shovel plate 5, and their number is not enough to be discharged backward to the support plate 4 by moving backward, so that the clods of soil continue to remain on the shovel plate 5, covering the blowing port 51 and affecting the blowing effect; therefore, a debris discharge port 52 is provided on the shovel plate 5; in the aforementioned steps, during the operation process of shoveling up soil for topdressing by the shovel head 6, the debris discharge port 52 is in a state of being closed by the flap 8, and the shoveled soil can smoothly move to the support plate 4 through the flap 8; and in the topdressing operation in which the shovel plate 5 is higher than the plastic film and the tobacco leaves are blown up by blowing, such as Figure 6 As shown, the user flips the flap 8 downward in advance to open the debris discharge port 52. When the shovel board 5 scoops up a small amount of soil, the soil will move backward and fall from the debris discharge port 52 with the inertia of movement, and fall back onto the plastic film under the shovel board 5, avoiding the shovel board 5 from accumulating a lot of soil and affecting the blowing port 51.

[0031] According to the above content, we know that the present invention has the following effects: The tobacco leaves are gathered between the two side baffles 2 by the side guide plates 3 and are limited by the two side baffles 2 to prevent the expanded tobacco leaves on both sides from being crushed and pulled by the tires of the topdressing vehicle 1 when the topdressing vehicle 1 passes through the tobacco planting rows, causing damage to the tobacco leaves and affecting the yield; at the same time, the shovel head 6 shovels up part of the soil around the tobacco plants and shovels up the tobacco leaves close to the ground, so that the tobacco leaves close to the ground do not block the surface of the planting ridges, making it convenient for the present invention to sprinkle fertilizer on the planting ridges for topdressing.

[0032] When the planting ridge is covered with plastic film, the oblique lower side of the shovel board 5 is 2-5 cm higher than the upper surface of the planting ridge, so that the oblique lower side of the shovel board 5 does not touch the plastic film on the planting ridge during its movement to prevent it from being damaged. At the same time, the air outlet 51 blows air to blow up the tobacco leaves close to the ground and onto the shovel board 5, so that the tobacco leaves close to the ground do not block the surface of the planting ridge, which is convenient for fertilization.

[0033] The shovel plate 5 is provided with a debris discharge port 52. When applying topdressing to tobacco covered with plastic film, after the shovel plate 5 scoops up a small amount of soil, the soil will move backward and fall from the debris discharge port 52 with the inertia of movement, and fall back onto the plastic film below the shovel plate 5, so as to avoid the shovel plate 5 accumulating a lot of soil and affecting the blowing port 51.

[0034] The additional technical effects of the present invention are as follows: like Figure 3 As shown, the side of the side guide plate 3 away from the side baffle plate 2 is configured to be rounded to prevent the side guide plate 3 from cutting off the tobacco leaves when contacting them.

[0035] Example 2 On the basis of Example 1, Figure 1-Figure 3 and Figure 7 As shown, the support plate 4 is rotatably connected to the side baffle plate 2; the shovel plate 5 is rotatably connected to the side guide plate 3; a nylon cloth 41 is commonly connected between the support plate 4 and the adjacent shovel plate 5; the side guide plate 3, support plate 4, nylon cloth 41, shovel plate 5, shovel head 6, air intake box 7 and flap 8 on each side baffle plate 2 form a forward topdressing mechanism, and a backward topdressing mechanism is added on the other side of each side baffle plate 2. The backward topdressing mechanism has the same structure as the forward topdressing mechanism and is symmetrically arranged on the same side baffle plate 2; at the same time, a fertilizer pipe 12 is added on the other side of the corresponding side baffle plate 2 and is connected to the storage box 11; a control valve is provided on the storage box 11, which can selectively supply material to a single fertilizer pipe 12; that is, the topdressing operation can be performed when the topdressing vehicle 1 of the present invention is moving forward or backward.

[0036] Each side baffle 2 is provided with two locking pins 102 that can slide up and down; each side guide plate 3 is also provided with a locking pin 102 that can slide up and down.

[0037] The following problems may also be encountered when using the present invention to topdress tobacco planted on a large scale: After topdressing one row of tobacco is completed, it is necessary to topdress the tobacco in the adjacent row. At this time, operating the topdressing vehicle 1 to turn around and topdress the tobacco in the adjacent row is inefficient, and a large space is required for the turnaround, and the turning operation is easily limited by the site space; therefore, by providing the same side guide plate 3, support plate 4, shovel plate 5 and other related structures for topdressing on the other side of the side baffle 2, the topdressing vehicle 1 of the present invention can perform topdressing operations whether moving forward or backward. When topdressing one row of tobacco is completed in the forward form, the rear side of the topdressing vehicle 1 is completely moved out of the row of tobacco. It only needs to be turned slightly to align the rear side of the topdressing vehicle 1 with the adjacent row of tobacco, and move in a backward manner to topdress the adjacent row of tobacco. There is no need to turn the topdressing vehicle 1 180 degrees, thereby improving the topdressing efficiency and being less restricted by the site space.

[0038] In addition, if Figure 3 As shown, when the topdressing vehicle 1 is advancing in a forward manner (the front of the topdressing vehicle 1 is facing forward), after pulling up the rear locking pin 102, the support plate 4 is flipped over and retracted and abutted against the side baffle 2, and the rear shovel plate 5 is flipped over and retracted (the corresponding locking pin 102 is pulled up first) and abutted against the side guide plate 3 on the rear side (when the support plate 4 and the shovel plate 5 are flipped over and retracted, the nylon cloth 41 connected between the two is correspondingly deformed), and then the corresponding locking pin 102 is lowered, and the support plate 4 and the shovel plate 5 are locked and limited. After the tobacco leaves guided by the front support plate 4 fall down, the support plate 4 and the shovel plate 5 that remain in a vertical state and abut against the side baffle 2 and the side guide plate 3 do not hinder the tobacco leaves, thereby avoiding shearing and damaging the tobacco. Leaves, because the fertilizer tube 12 is cylindrical, the tobacco leaves in contact can slide along the tube surface, further reducing obstacles; and when the topdressing vehicle 1 is performing topdressing in the form of retreat, the user lifts the locking pin 102 so that it no longer restricts the support plate 4 and the shovel plate 5, and then flips the rear support plate 4 and the shovel plate 5 downward so that they are in the same working state as the front support plate 4 and the shovel plate 5, and then pulls up the locking pins 102 corresponding to the front support plate 4 and the shovel plate 5, flips the front support plate 4 and the shovel plate 5 upward and retracts them, and finally puts down the corresponding locking pin 102 to lock the front support plate 4 and the shovel plate 5, so as to avoid the front support plate 4 and the shovel plate 5 being horizontal and causing obstacles to the tobacco leaves when retreating for topdressing.

[0039] It should be noted that when the shovel plate 5 is turned up and retracted, the corresponding shovel head 6 is removed first to avoid affecting the fitting effect between the shovel plate 5 and the side guide plate 3 .

[0040] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
