Description

Technical Field

[0001] The invention belongs to the field of vegetation heat preservation, in particular to a device and method for heat preservation of northern peaches during winter. Background Art

[0002] Peach tree is a common fruit tree. Northern peach mainly refers to the peach variety planted in the northern region. The temperature in the north is relatively low in winter. Although northern peach has strong cold resistance, it is difficult to survive the northern winter without protection.

[0003] The traditional way to keep peach trees warm in winter is to use a multi-layer covering method. First, when planting peach trees, they need to be kept at a certain tilt angle for growth. When winter is coming, straw, straw curtains and colored strips are used to cover the top of the peach trees. The covering direction needs to be along the tilt direction of the peach trees. The peach trees are bent, and then three layers of coverings are covered on the peach trees to keep them warm. However, bending a peach tree not only requires a great deal of force, but also, although the peach tree is grown at an angle, it still has a certain height, and it is rather difficult to bend it manually. In addition, strong winds are prone to occur during the winter, and since most of the covering is covered on the peach tree by gravity, it is easy for part of it to be overturned in windy weather. When the gravity is insufficient, the peach tree will push away the remaining covering, causing the insulation effect to fail.

[0004] To this end, the present invention provides a northern peach wintering heat preservation device and heat preservation method. Summary of the invention

The power vehicle drives the power box 1 to move, and the power box 1 can control the pulling frame 9 to lift and lower. First, the pulling frame 9 is moved upward to allow the thermal insulation blanket 2 to be expanded as much as possible, and then as the power box 1 moves, the thermal insulation blanket 2 is covered on the surface of the peach tree, and then the pulling frame 9 is pressed down, and the power box 1 moves forward at the same time, so that the thermal insulation blanket 2 can cover the outside of the peach tree. At the same time, the peach tree is mechanically bent, and then straw and other coverings can be stacked on the surface of the thermal insulation blanket 2. Since the peach tree has been bent at this time, the stacking process of other coverings is greatly facilitated. Then the power box 1 drives the pressing box 3 to move to the front end of the thermal insulation blanket 2, and the front end of the thermal insulation blanket 2 is also fixed to the ground using the fixing nails 16, thus ensuring that the peach tree is firmly pressed by the thermal insulation blanket 2. Through this arrangement, not only the process of bending the peach tree is facilitated, but also because the elastic potential energy of the peach tree is firmly suppressed by the thermal insulation blanket 2, even if other coverings on the top surface of the thermal insulation blanket 2 are partially lifted up by strong winds, the peach tree will not overturn the thermal insulation blanket 2 and other coverings, thereby ensuring the long-term thermal insulation process of the peach tree in winter.

[0022] A vertically arranged screw nut mechanism 21 is installed inside the power box 1, and a moving end of the screw nut mechanism 21 is located outside the power box 1. The moving end is fixedly connected with a docking shaft 18, and the docking shaft 18 is connected to the pulling frame 9. A slide groove 22 for passing the moving end of the screw nut mechanism 21 is provided on the outside of the power box 1; During operation, the screw nut mechanism 21 drives the docking shaft 18 and the pulling frame 9 to rise and fall, thereby driving the front end of the thermal insulation blanket 2 to rise and fall. With the overall advancement of the power box 1, the peach tree can be bent. The setting of the slide groove 22 allows the docking shaft 18 to slide on the surface of the power box 1.

[0023] Both ends of the thermal insulation blanket 2 are fixedly connected with connection pads 11, and the ends of the connection pads 11 are fixedly connected with fixing strips 19, and a plurality of connection rings 10 are fixedly connected to the top surface of the fixing strips 19 close to the pulling frame 9, and the pulling frame 9 passes through the plurality of connection rings 10, and a steel cable 23 is fixedly connected between the end of the pulling frame 9 and the top of the power box 1, and the pulling frame 9 is threadedly connected with the docking shaft 18; During operation, the pulling frame 9 passes through a plurality of connecting rings 10 to control the connecting pad 11 at the front end of the thermal insulation blanket 2. The setting of the second steel cable 23 is used to ensure that the pulling frame 9 has sufficient force to pull the thermal insulation blanket 2 forward. When the thermal insulation blanket 2 is fixed in place, it can first contact the second steel cable 23, and then the pulling frame 9 is released from the docking shaft 18, and then the pulling frame 9 is fixed to the next connecting pad 11, which facilitates the removal and connection process of the pulling frame 9.

[0024] A support frame 4 is fixedly connected to the side of the power box 1 close to the pressing box 3, a reduction motor 5 is fixedly connected to the top surface of the support frame 4, a transmission arm 13 is fixedly connected to the output end of the reduction motor 5, the transmission arm 13 is fixedly connected to the pressing box 3, a convex plate is fixedly connected to the side of the pressing box 3 close to the power box 1, a winding box 20 is installed on one side of the pressing box 3, an electric winding roller is installed inside the winding box 20, and a steel cable 14 is fixedly connected to the outer side of the electric winding roller and the end of the pressing box 3 away from the power box 1; During operation, after the pressing box 3 fixes the rear end of the thermal insulation blanket 2, the reduction motor 5 is started, and the pressing box 3 is driven to rotate by the transmission arm 13 to make the pressing box 3 become vertical. In this way, when the power box 1 moves forward to pull the thermal insulation blanket 2, the pressing box 3 will not affect the unfolding work of the thermal insulation blanket 2. At the same time, when the peach tree is difficult to press down, the pressing box 3 can also be rotated to press the part of the peach tree that is difficult to bend, so as to assist its bending process. The steel cable 14 pulls the pressing box 3 synchronously during the operation of the reduction motor 5, and the steel cable 14 can pull one end of the pressing box 3 by winding the electric winding roller to assist the rotation process of the pressing box 3. The setting of the convex plate is to allow the convex plate to contact the support frame 4 when the pressing box 3 becomes vertical, so as to bear part of the weight of the pressing box 3.

[0025] A plurality of through holes are formed on the top surface of the connection pad 11, and a protective ring 12 is fixedly connected to the through hole. The fixing nail 16 is wide at the top and narrow at the bottom, and the width of the top surface of the fixing nail 16 is greater than the width of the protective ring 12; During operation, the fixing nails 16 pass through the protection ring 12 from top to bottom, the bottom of the fixing nails 16 penetrates into the soil, and the top of the fixing nails 16 remains above the protection ring 12, thereby ensuring the effect of firmly fixing the connection pad 11 on the ground.

Then, the top of the fixing nail 16 is impacted multiple times by the upper hydraulic rod 6 to drive the fixing nail 16 into the ground.

[0027] An electromagnetic valve 17 is installed on the outer side of the inclined tube, and the movable end of the electromagnetic valve 17 is located inside the delivery tube 7.

[0028] The thermal insulation blanket 2 is made of wear-resistant material, and a plurality of binding ropes 15 are arranged on the outside of the thermal insulation blanket 2. The binding ropes 15 penetrate the rolled thermal insulation blanket 2, and the plurality of binding ropes 15 are linearly and equidistantly arranged. During operation, the setting of the binding rope 15 allows the thermal insulation blanket 2 to remain in a curled state at the beginning. As the pulling frame 9 pulls, the binding rope 15 will be broken, allowing the thermal insulation blanket 2 to be normally unfolded.

[0029] like Figure 7 As shown, a method for heat preservation of northern peaches during winter is applicable to the device for heat preservation of northern peaches during winter. The method is specifically as follows: S1: Use the connecting frame 8 to install the power box 1 on one side of the agricultural power vehicle, place the insulation blanket 2 on one side of the peach tree, press the one end of the insulation blanket 2 on the ground with the pressing box 3, and use the hydraulic rod 6 to penetrate and fix the insulation blanket 2 on the ground with multiple fixing nails 16; S2: Use the pulling frame 9 to fix the other end of the thermal insulation blanket 2, and the power vehicle drives the power box 1 to move. At the same time, the power box 1 can control the pulling frame 9 to move up and down. First, move the pulling frame 9 upward to allow the thermal insulation blanket 2 to be spread out as much as possible; S3: Then, as the power box 1 moves, the insulation blanket 2 covers the surface of the peach tree, and then the pulling frame 9 is pressed down, while the power box 1 moves forward, so that the insulation blanket 2 covers the outside of the peach tree, and the peach tree is mechanically bent, and finally straw and other covering materials are stacked on the surface of the insulation blanket 2 to complete the covering and insulation process.

[0030] The process of mechanically bending peach trees in S3 is as follows: Q1: The screw nut mechanism 21 drives the docking shaft 18 and the pulling frame 9 to move up and down, thereby driving the front end of the thermal insulation blanket 2 to move up and down; Q2: With the overall forward movement of the power box 1, the peach tree can be bent.

[0031] During operation, the power box 1 is set up and the connecting frame 8 is used to install the power box 1 on one side of the agricultural power vehicle, and the thermal insulation blanket 2 is placed on one side of the peach tree. The pressing box 3 presses one end of the thermal insulation blanket 2 on the ground, and the hydraulic rod 6 is used to penetrate and fix the thermal insulation blanket 2 on the ground with multiple fixing nails 16, and then the pulling frame 9 is used to fix the other end of the thermal insulation blanket 2. The power vehicle drives the power box 1 to move, and the power box 1 can control the pulling frame 9 to lift and lower. First, the pulling frame 9 is moved upward to allow the thermal insulation blanket 2 to be expanded as much as possible, and then as the power box 1 moves, the thermal insulation blanket 2 is covered on the surface of the peach tree, and then the pulling frame 9 is pressed down, and the power box 1 moves forward at the same time, so that the thermal insulation blanket 2 can cover the surface of the peach tree. On the outside, the peach tree is mechanically bent at the same time, and then straw and other coverings can be stacked on the surface of the thermal insulation blanket 2. Since the peach tree has been bent at this time, the stacking process of other coverings is greatly facilitated. Then the power box 1 drives the pressing box 3 to move to the front end of the thermal insulation blanket 2, and the front end of the thermal insulation blanket 2 is also fixed to the ground using the fixing nail 16, so that the peach tree is firmly pressed by the thermal insulation blanket 2. Through this arrangement, not only the process of bending the peach tree is convenient, but also because the elastic potential energy of the peach tree is firmly suppressed by the thermal insulation blanket 2, even if other coverings on the top surface of the thermal insulation blanket 2 are partially lifted by strong winds, the peach tree will not overturn the thermal insulation blanket 2 and other coverings, thereby ensuring the long-term heat preservation process of the peach tree in winter; The screw nut mechanism 21 drives the docking shaft 18 and the pulling frame 9 to move up and down, thereby driving the front end of the thermal insulation blanket 2 to move up and down, and the peach tree can be bent by cooperating with the overall advancement of the power box 1. The setting of the slide groove 22 allows the docking shaft 18 to slide on the surface of the power box 1; The pulling frame 9 passes through a plurality of connecting rings 10 to control the connecting pad 11 at the front end of the thermal insulation blanket 2. The second steel cable 23 is provided to ensure that the pulling frame 9 has sufficient force to pull the thermal insulation blanket 2 forward. When the thermal insulation blanket 2 is fixed in place, the second steel cable 23 can be contacted first, and then the pulling frame 9 is released from the docking shaft 18, and then the pulling frame 9 is fixed to the next connecting pad 11, which facilitates the removal and connection process of the pulling frame 9; After the pressing box 3 fixes the rear end of the thermal insulation blanket 2, the reduction motor 5 is started, and the pressing box 3 is driven to rotate by the transmission arm 13, so that the pressing box 3 becomes a vertical state. In this way, when the power box 1 moves forward to pull the thermal insulation blanket 2, the pressing box 3 will not affect the unfolding work of the thermal insulation blanket 2. At the same time, when the peach tree is difficult to press down, the pressing box 3 can also be rotated to press the part of the peach tree that is difficult to bend, so as to assist its bending process. The steel cable 14 pulls the pressing box 3 synchronously during the working process of the reduction motor 5, and the steel cable 14 can pull one end of the pressing box 3 by the winding of the electric winding roller to assist the rotation process of the pressing box 3. The setting of the convex plate is to allow the convex plate to contact the support frame 4 when the pressing box 3 becomes vertical, so as to bear part of the weight of the pressing box 3. The fixing nail 16 passes through the protection ring 12 from top to bottom, the bottom of the fixing nail 16 pierces into the soil, and the top of the fixing nail 16 remains above the protection ring 12, thereby ensuring the effect of firmly fixing the connection pad 11 on the ground; The required fixing nail 16 is placed into the delivery tube 7 through the inclined tube. When the fixing nail 16 passes through the inclined tube and reaches the straight tube, it will automatically straighten itself into a vertical state. Then, the top of the fixing nail 16 is impacted multiple times by the upper hydraulic rod 6, so that the fixing nail 16 can be driven into the ground. The provision of the binding rope 15 allows the thermal insulation blanket 2 to remain in a curled state at the beginning. As the pulling frame 9 pulls, the binding rope 15 will be broken, allowing the thermal insulation blanket 2 to be normally unfolded.
