Description

Technical Field

[0001] The invention relates to the technical field of agricultural production, and in particular to a soil covering and film covering device for planting papaya. Background Art

[0002] Papaya is a tropical plant that has high requirements for the growth environment. Suitable climate, soil, light and other conditions are essential for its growth. Under good humidity and temperature conditions, the root system of papaya develops more vigorously, which helps it to better absorb nutrients and water, making the growth rate of papaya faster, shortening the time from planting to harvesting, and increasing the yield of the fruit.

[0003] Soil covering and film mulching is an agricultural technology that usually involves covering the soil surface with plastic film to achieve the purpose of heat preservation, moisture retention, and weed control. The plastic film is spread evenly on the soil surface and the edges are fixed with soil or other heavy objects to ensure that the film fits tightly to the soil. The film layer can prevent heat loss. At night or in cold weather, the temperature inside the film is relatively high, protecting the root system and plant growth. The film covering reduces the evaporation of soil moisture, keeps the soil moist, and helps the crop roots absorb moisture.

[0004] When planting papaya, you need to use wooden stakes to pierce the film covering the soil, make planting holes, and plant the cultivated papaya seedlings in the planting holes. Providing planting holes for the seedlings will help the roots to penetrate the soil, absorb nutrients and water, and facilitate plant growth.

[0005] The existing soil covering and film covering devices cannot automatically make planting holes at equal intervals on the film layer while covering the soil and film. After the film covering work is completed, the planting holes need to be opened manually. In order to ensure that the planting holes are opened at equal intervals, manual distance measurement is required for each planting hole opened, and the entire operation process is not efficient enough.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. Move the device to the designated position, pull the plastic film from the rolled film, pass it through the gap between the two rotating drums, and stick it to the soil surface, start the second hydraulic pump, extend the output shaft of the second hydraulic pump, and make the pressure rod press the side plate with the blunt pressing head downward, and press the blunt pressing head to press the end of the plastic film into the soil, then start the second hydraulic pump again, shorten the output shaft of the second hydraulic pump, lift the pressure rod upward to the side plate with the blunt pressing head, take the blunt pressing head out of the soil, manually fill the soil and bury the position where the end of the plastic film is pressed, and move the driving device forward.

The bulldozer can push the soil at both ends of the drum toward the drum to press and fix the edge of the plastic film. At the same time, it can also push part of the soil into the drum from the open end of the drum. As the drum rotates, when the soil outlet of the drum with soil inside turns downward, the soil falls from the soil outlet to the upper surface of the plastic film to cover the plastic film.

[0024] 2. With the rotation of the drum, the auxiliary wheel will continuously move along the outer circumference of the cam, and the vertical moving rod will continuously reciprocate in upward and downward movement, driving the hammer rod to reciprocate in downward and upward movement, thereby regularly performing the piling work.

The above operation is repeated until there are no planting piles in the conveying trough, and the hydraulic pump 2 is started again to make the pressure rod press down the side plate with the pressing blunt head, and the pressing blunt head presses the other end of the plastic film into the soil, and the position where the plastic film end is pressed is manually filled with soil and buried, and then the hydraulic pump 2 on the other side is started to make the pressure rod press down the side plate with the cutting head, so that the cutting head cuts the plastic film, and then the cutting head and the pressing blunt head are lifted up and retracted. The spacing of the fallen soil is related to the cross-sectional circumference of the roller. The spacing of the fallen soil is the distance of the cross-sectional circumference of the roller. The pressed planting piles are located in the middle of the two piles of fallen soil. The distances between the planting holes are consistent. The planting piles will be pulled out later and the papaya plants will be transplanted into the planting holes. Planting with equal spacing can effectively reduce competition between plants, ensuring that each plant can obtain sufficient nutrients and water to promote its healthy growth.

[0025] 3. In order to prevent the plastic film on the rolled film from spreading out, it needs to be rewound, start the hydraulic pump 1, shorten the output shaft of the hydraulic pump 1, pull back the connecting seat, pull the multiple claws toward the center of the baffle plate through the pull rod, clamp and fix the rolled film, and prevent the plastic film from spreading out on a large scale.

[0063] like Fig.13As shown, the hammer pressing assembly 91 is arranged at the upper end of the roller 8, and the hammer pressing assembly 91 includes a side frame 911, a vertical shift rod 912 and a hammer rod 913. The side frame 911 is arranged above the cam 81, and the side frame 911 is fixed on the frame 1. The side frame 911 and the rear frame 13 are fixedly connected. The vertical shift rod 912 consists of a vertical bar and a horizontal bar. The vertical bar of the vertical shift rod 912 is slidably connected to the side frame 911. The lower end of the vertical bar of the vertical shift rod 912 is tangent to the outer peripheral surface of the cam 81. The lower end of the vertical bar of the vertical shift rod 912 is rotatably connected to an auxiliary wheel 9122. A jacket spring 9121 is arranged on the outer side of the vertical bar of the vertical shift rod 912. The jacket spring 9121 is arranged between the side frame 911 and the auxiliary wheel 9122. The auxiliary wheel 9122 contacts and is tangent to the outer peripheral surface of the cam 81. The axis of the auxiliary wheel 9122 is parallel to the axis of the cam 81, and the outer sleeve spring 9121 can ensure that the cam 81 and the auxiliary wheel 9122 are always in close contact. The hammer rod 913 is arranged on the horizontal bar of the vertical moving rod 912, and the free end of the hammer rod 913 is fixedly connected with a hammer head 9131. The lower end of the hammer rod 913 is provided with a support member, and the connection point between the support member and the hammer rod 913 is close to the end of the hammer rod 913 that is closer to the horizontal bar of the vertical moving rod 912. The support member is used to support the rotation of the hammer rod 913, and the rotation center of the hammer rod 913 is the connection point between the support member and the hammer rod 913. When the vertical moving rod 912 moves, the hammer rod 913 can benefit from the lever principle, and can effectively amplify the stroke amplitude of the hammer head 9131, thereby achieving greater striking force.

[0064] There are two embodiments of the hammer assembly 91.

[0065] In the first embodiment, if Fig.14 As shown, the support member is a telescopic rod 914, the sleeve portion of the telescopic rod 914 is rotatably connected to the upper end of the cross bar 133, the sliding portion of the telescopic rod 914 is rotatably connected to the hammer rod 913, and the hammer rod 913 is rotatably connected to the cross bar of the vertical displacement rod 912. The sliding portion of the telescopic rod 914 can slide along the sleeve portion.

[0066] In the second embodiment, if Fig.15 As shown, the support member is a support rod 9141, one end of the support rod 9141 is fixed to the upper end of the cross bar 133, the other end of the support rod 9141 is rotationally connected to the hammer rod 913, a free groove 9132 is penetrated through the side of the hammer rod 913, and the cross bar of the vertical moving rod 912 is slidably connected to the hammer rod 913 through the free groove 9132.

[0067] During the movement of the device, the drum 8 will rotate, and the cam 81 set on the side of the drum 8 will also rotate synchronously. Because the long axis of the cam 81 is located in the direction of the soil outlet 82, when the long axis of the cam 81 is at the top and the short axis is at the bottom, the soil outlet 82 faces upward, and the soil will not fall out of the soil outlet 82 at this time. During the upward movement of the long axis, the vertical moving rod 912 will be pushed upward, and under the support of the support, the hammer rod 913 will rotate downward around the connection point between the support and the hammer rod 913, and the hammer head 9131 will press the firing column 922 downward, and the firing column 922 will move down along the outer cylinder 921, so that the planting pile 10 moves down and pierces the plastic film 31 and presses it into the soil, thereby achieving the effect of making a planting hole. After the planting pile 10 is pressed into the soil, the planting pile 10 can be manually knocked again to ensure the insertion depth of the planting pile 10. Papaya is planted in sandy loam, and the soil in the sandy loam is loose and easy to stake.

[0068] When the auxiliary wheel 9122 at the lower end of the vertical moving rod 912 is located at the farthest point of the long axis of the cam 81, the vertical moving rod 912 is pushed up to the highest point, at which time the hammer rod 913 droops and the hammer head 9131 is at the lowest point; when the auxiliary wheel 9122 at the lower end of the vertical moving rod 912 is located at the farthest point of the short axis of the cam 81, the vertical moving rod 912 sinks to the lowest point, at which time the hammer rod 913 is tilted up and the hammer head 9131 is at the highest point.

[0069] As the drum 8 rotates, the auxiliary wheel 9122 will continuously move along the outer circumference of the cam 81, and the vertical moving rod 912 will continuously reciprocate in upward and downward movement, driving the hammer rod 913 to reciprocate in downward and upward movement, thereby regularly performing the piling work. The spacing of the fallen soil is related to the cross-sectional circumference of the drum 8. The spacing of the fallen soil is the distance of the cross-sectional circumference of the drum 8. The pressed planting piles 10 are located in the middle of the two piles of fallen soil, and the distances between the planting holes are consistent. Subsequently, the planting piles 10 will be pulled out and the papaya plants will be transplanted into the planting holes. Planting at equal spacing can effectively reduce competition between plants, ensure that each plant can obtain sufficient nutrients and water, and promote their healthy growth. When performing the piling work of the planting piles 10, there is no need to rely on a power device for driving, thus saving costs.

[0070] like Fig.16As shown, the pile delivery assembly 92 is arranged below the hammer pressure assembly 91, and the pile delivery assembly 92 includes an outer tube 921, a firing column 922, a striking head 923, an elastic member 924, a pile delivery frame 925 and a pushing member.

A plurality of planting piles 10 are arranged in the conveying groove 9251, and a pushing member for pushing the planting piles 10 to move into the guide cylinder 9252 is provided inside the conveying groove 9251. The pushing member includes a pushing plate 926 and an elastic member 927. The pushing plate 926 is slidably connected to the pile conveying frame 925, and an elastic member 927 is provided on the pushing plate 926. One end of the elastic member 927 is provided on the guide cylinder 9252. When the planting pile 10 located inside the guide cylinder 9252 is pressed out by the firing column 922 , the elastic member 927 is reset to pull the push plate 926 back, and the following planting pile 10 is pushed into the guide cylinder 9252 . The above operation is repeated until there is no planting pile 10 in the conveying groove 9251 .

[0071] like Fig.19 and Fig. 20As shown, the upper end of the planting pile 10 is provided with a pile head 101, and the connection between the pile head 101 and the planting pile 10 is provided with a chamfer. The inner sides of the conveying groove 9251 and the guide cylinder 9252 are fixedly connected with a limiting strip 9253. The pile head 101 is provided at the upper end of the limiting strip 9253 of the conveying groove 9251 and the guide cylinder 9252. The upper end of the side of the limiting strip 9253 is provided with a chamfer. The chamfer of the limiting strip 9253 corresponds to the chamfer of the pile head 101. The limiting strip 9253 located on the inner side of the guide cylinder 9252 may not be provided in a circular ring shape, but only retains a few small sections of the circular ring, so that the pile head 101 can break through the limiting strip 9253 and move downward. The limiting strip 9253 plays a supporting role for the pile head 101. The limiting strip 9253 provided with a chamfer is thin and narrow, so that when the planting pile 10 is subjected to downward pressure, the limiting strip 9253 can be pressed out.

[0072] Using the present invention, Figure 1 and Figure 2As shown, the device is moved to the specified position, the plastic film 31 is pulled out from the rolled film 3, passed through the gap between the two rotating drums 41, and attached to the soil surface, the hydraulic pump 2 61 is started, the output shaft of the hydraulic pump 2 61 is extended, the pressure rod 62 presses downward the side plate 51 equipped with the pressing blunt head 53, and the pressing blunt head 53 presses the end of the plastic film 31 into the soil, and then the hydraulic pump 2 61 is started again to shorten the output shaft of the hydraulic pump 2 61, so that the pressure rod 62 lifts upward the side plate 51 equipped with the pressing blunt head 53, and the pressing blunt head 53 is taken out of the soil, and the position where the end of the plastic film 31 is pressed is manually filled with soil and buried, the driving device moves forward, and the two soil-breaking cones 15 can open two grooves on the soil, so that a convex ridge is formed between the two grooves, and the film pressing wheel 7 moves in the groove, and the film pressing wheel 7 is attached to both sides of the ridge, and the film pressing wheel 7 can press the two sides of the plastic film 31 covering the ridge into the grooves on both sides of the ridge. During the movement of the device, the roller 8 will roll, and the cam 81 set on the side of the roller 8 will also rotate synchronously. The bulldozer 83 can push the soil at both ends of the roller 8 toward the roller 8 to press and fix the edge of the plastic film 31. At the same time, part of the soil can also be pushed into the roller 8 from the open end of the roller 8. As the roller 8 rotates, when the soil outlet 82 of the roller 8 with soil inside turns downward, the soil falls from the soil outlet 82 to the upper surface of the plastic film 31 to cover the plastic film 31. As the roller 8 rotates, the auxiliary wheel 9122 will continuously move along the outer circumference of the cam 81, and the vertical moving rod 912 will continuously reciprocate in upward and downward movement, driving the hammer rod 913 to reciprocate in downward and upward movement, thereby regularly performing the piling work. When the planting pile 10 located inside the guide cylinder 9252 is pressed out by the firing column 922, the elastic member 927 is reset to pull the push plate 926 back, and the subsequent planting pile 10 is pushed into the guide cylinder 9252.

In order to prevent the plastic film 31 on the rolled film 3 from spreading and needing to be rewound, the hydraulic pump 1 23 is started to shorten the output shaft of the hydraulic pump 1 23, and the connecting seat 24 is pulled back, and the multiple claws 26 are pulled toward the center of the baffle 22 by the pull rod 25 to clamp and fix the rolled film 3 to prevent the plastic film 31 from spreading over a large range.The spacing of the fallen soil is related to the cross-sectional circumference of the roller 8. The spacing of the fallen soil is the distance of the cross-sectional circumference of the roller 8. The pressed planting piles 10 are located in the middle of the two piles of fallen soil. The distances between the planting holes are consistent. Subsequently, the planting piles 10 are pulled out and the papaya plants are transplanted into the planting holes. Planting with equal spacing can effectively reduce competition between plants, ensure that each plant can obtain sufficient nutrients and water, and promote its healthy growth.
