DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0029] Embodiment 1: Figure 1-Figure 4 As shown, a greenhouse soil loosening device described in an embodiment of the present invention comprises a U-shaped frame 1, a beveled block 14 is provided at the lower end of the U-shaped frame 1, the interior of the beveled block 14 is a hollow structure, a first cylinder 141 is fixedly connected to one side of the lower end of the beveled block 14, the beveled block 14 is communicated with the interior of the first cylinder 141, a second cylinder 142 is slidably connected to the lower end of the first cylinder 141, a first cylindrical rod 15 is rotatably connected to the middle of the first cylinder 141, a spiral conveying sheet 151 is fixedly connected to the outer side of the first cylindrical rod 15, a U-shaped block 13 is fixedly connected to the upper end of the middle of the beveled block 14, a second cylindrical block 32 is fixedly connected to the upper end of the U-shaped block 13, the second cylindrical block 32 passes through the middle of the U-shaped frame 1, the second cylindrical block 32 can rotate in the middle of the U-shaped frame 1, and a second rectangular hole 17 is opened in the middle of the lower end of the beveled block 14.

[0030] Specifically, when loosening the soil in the greenhouse, due to the limited space in the greenhouse, it is necessary to make full use of the planting space in the greenhouse. When loosening the soil in the greenhouse, it is necessary to fully loosen the soil at the edge of the greenhouse so as to plant more crops. When the loosening device moves to the edge of the greenhouse, it is necessary to turn around and change lanes to continue loosening the soil. It is inconvenient to turn the loosening device around when it is close to the edge of the greenhouse. The plastic film of the greenhouse may be scratched during the turning process, and it is more troublesome to carry the machine during the turning process. When using the present invention, the U-shaped frame 1 is placed on the land, the second cylinder 142 contacts the ground, and the second cylinder 142 slides toward the inside of the first cylinder 141, and the first cylindrical rod 15 drives The spiral conveyor plate 151 rotates, and the first cylindrical rod 15 rotates toward the inside of the land. The spiral conveyor plate 151 conveys the soil upward when it rotates, and then the soil falls into the inside of the bevel block 14, and then falls on the land through the second rectangular hole 17. The soil can be dug out by the rotation of the spiral conveyor plate 151 and then spread on the ground again to loosen the soil. When a U-turn is required, the second cylindrical block 32 is driven to rotate, and the second cylindrical block 32 drives the bevel block 14 to rotate 180 degrees, so that the direction of the spiral conveyor plate 151 is rotated 180 degrees. The loosening direction can be changed without moving the loosening device as a whole, which solves the problem that the space in the greenhouse is small and it is inconvenient to turn the loosening device when approaching the edge of the greenhouse.

[0031] like Figure 1-Figure 3 As shown, the U-shaped frame 1 in this embodiment is respectively fixed with a first rectangular bar 11 on both sides of the lower end, the first rectangular bar 11 is respectively fixed with a second rectangular bar 12 on both sides of the lower end, the second rectangular bar 12 is respectively slidably connected with a third rectangular bar 121 at the lower end, the third rectangular bar 121 is respectively fixed with wheels 122 at the lower ends, the U-shaped block 13 is respectively slidably connected with a first rectangular plate 131 on both sides of the lower end, the first rectangular plate 131 is fixedly connected to the second cylinder 142 through a connecting bracket 143, and the connecting bracket 143 is respectively fixed with pointed strips 1431 on both sides of the lower end.

[0032] Specifically, the third rectangular bar 121 and the second rectangular bar 12 provided at the four corners of the lower end of the U-shaped frame 1 support the bevel block 14, and the wheels 122 facilitate the movement of the loosening device. When the U-shaped frame 1 is pushed to move for loosening the soil, the pointed bars 1431 provided on both sides of the lower end of the connecting bracket 143 are inserted into the ground on one side to reduce the resistance generated during movement.

[0033] like Figure 4 As shown, in this embodiment, a first rotating assembly is provided inside the bevel block 14 near the first cylinder 141 , and the first rotating assembly includes a second cylindrical rod 16 rotatably connected to the middle of the bevel block 14 , and a plurality of third arc strips 161 are fixedly connected to the outer side of the second cylindrical rod 16 .

[0034] Specifically, if the soil in the greenhouse is not taken care of for a long time, a lot of weeds will grow. The fruits of some crops need to be covered with plastic bags on the outside during the growth process. There may be fallen plastic bags in the soil. When loosening the soil, the weeds and plastic bags need to be removed in time. When using the present invention, after the spiral conveyor sheet 151 digs out the soil, the second cylindrical rod 16 is driven to rotate and the third arc-shaped bar 161 is driven to rotate. In the process of the soil falling into the bevel block 14, a hook is provided at the end of the third arc-shaped bar 161. The rotating third arc-shaped bar 161 hooks out the plastic bags and weeds in the soil, and the remaining soil falls to the ground through the second rectangular hole 17. By rotating the third arc-shaped bar 161, the weeds and plastic bags in the soil can be hooked out while loosening the soil to prevent affecting the growth of crops.

[0035] like Figure 2-Figure 4 As shown, in this embodiment, a second rotating assembly is provided at the upper end of the first rotating assembly, and the second rotating assembly has the same structure as the first rotating assembly. The third arc-shaped bar 161 provided on the outer side of the second rotating assembly is staggered with the third arc-shaped bar 161 provided on the outer side of the first rotating assembly. A motor 152 is fixedly connected to the upper end of the first cylindrical rod 15, and the motor 152 is fixedly connected to the upper end of the bevel block 14 through a motor seat. A first rectangular hole 144 is provided on one side of the upper end of the bevel block 14, and a A T-shaped slider 1441, one side of which is fixedly connected to the motor base via a first spring 1442, the lower end of which is fixedly connected to a fifth rectangular bar 1444 via a fourth rectangular bar 1443, the lower end of which is slidably connected to a sixth rectangular bar 1445, one side of which is fixedly connected to a plurality of second arc-shaped bars 1446, the second arc-shaped bars 1446 are staggered with the third arc-shaped bars 161, and cover plates 145 are installed on both sides of the bevel block 14.

[0036] Specifically, after the third arc-shaped bar 161 hooks out the plastic bag and weeds, it continues to rotate and then passes between the second arc-shaped bars 1446. Several third arc-shaped bars 161 slide between several second arc-shaped bars 1446, leaving the plastic bag and weeds on the upper end of the second arc-shaped bar 1446. When there are too many plastic bags and weeds on the upper end of the second arc-shaped bar 1446, they need to be taken out in time. At this time, the T-shaped slider 1441 is driven to slide in the first rectangular hole 144 toward the side close to the third arc-shaped bar 161 and squeeze the first spring 1442. At the same time, the second arc-shaped bar 1446 slides upward along the second cylindrical rod 16 and drives the sixth rectangular bar 1445 to slide into the inside of the fifth rectangular bar 1444. Then the cover plate 145 is opened to take out the plastic bag and weeds.

[0037] like Figure 4As shown, in this embodiment, a crushing assembly is provided in the middle of the second rectangular hole 17, and the crushing assembly includes a third cylindrical rod 171 rotatably connected to both sides of the middle of the second rectangular hole 17, and extrusion blocks 172 are fixed to the outer sides of the third cylindrical rod 171, and the extrusion blocks 172 located on both sides are staggered with each other.

[0038] Specifically, the soil without plastic bags and weeds falls into the lower end of the bevel block 14, and the third cylindrical rod 171 is driven to rotate to drive the extrusion block 172 to rotate. The extrusion blocks 172 on both sides rotate at the same time to further crush the soil and make the soil softer.

[0039] like Figure 4 As shown, in this embodiment, a second rectangular plate 18 is fixedly connected to one side of the inner side of the bevel block 14 , a third rectangular plate 181 is slidably connected to the lower end of the second rectangular plate 18 , and a fourth rectangular plate 182 is fixedly connected to one side of the third rectangular plate 181 .

[0040] Specifically, after planting for a period of time, the nutrients in the soil are gradually lost, and the soil needs to be fertilized regularly during planting. When using the present invention, fertilizer is placed on one side of the second rectangular plate 18 inside the bevel block 14. When the third cylindrical rod 171 rotates to drive the extrusion block 172 to rotate, the extrusion block 172 rotates to push the fourth rectangular plate 182 upward, and the fourth rectangular plate 182 drives the third rectangular plate 181 to slide into the second rectangular plate 18, and the third rectangular plate 181 is lifted upward, and the fertilizer flows out from under the third rectangular plate 181 and mixes in the soil. After the extrusion block 172 rotates, the fertilizer and the soil are fully mixed and then fall to the ground.

[0041] like Figure 6 As shown, in this embodiment, the upper end of the second cylindrical block 32 is fixedly connected to the first cylindrical block 3, and rectangular grooves 31 are opened on both sides of the first cylindrical block 3. Rectangular sliders 33 are slidably connected in the rectangular grooves 31, and the rectangular sliders 33 are fixedly connected to one side of the rectangular grooves 31 through a second spring 331. One end of the rectangular slider 33 is rotatably connected to a circular plate 332.

[0042] Specifically, when it is necessary to drive the loosening device to turn around, the rectangular slider 33 is driven to slide in the rectangular groove 31 and squeeze the second spring 331, and then the rectangular slider 33 is driven to rotate. The rectangular slider 33 drives the second cylindrical block 32 to rotate 180 degrees through the first cylindrical block 3, so that the circular plate 332 rotates at the upper end of the U-shaped frame 1, and then the circular plate 332 is located on both sides of the U-shaped frame 1. Then the second spring 331 releases the elastic force, pushing the rectangular slider 33 to drive the circular plate 332 to be close to both sides of the U-shaped frame 1. At this time, the U-turn is completed.

[0043] like Figure 5As shown, in this embodiment, the four corners of the U-shaped frame 1 are respectively slidably penetrated by the seventh rectangular bar 24, the lower ends of the seventh rectangular bar 24 are respectively fixedly connected to the third rectangular bar 121 through rectangular blocks 241, the upper ends of the seventh rectangular bar 24 are commonly fixedly connected to the fifth rectangular plate 2, the middle part of the fifth rectangular plate 2 is fixedly connected with a circular ring 21, the middle part of the circular ring 21 is threadedly connected with a screw rod 22, and the lower end of the screw rod 22 can rotate on the first cylindrical block 3.

[0044] Specifically, different crops have different planting conditions, and different loosening depths need to be adjusted according to different types of crops when loosening the soil. When using the present invention, the driving screw 22 is rotated to drive the fifth rectangular plate 2 to move upward through the ring 21, and at the same time drive the seventh rectangular bar 24 to move upward. The seventh rectangular bar 24 drives the third rectangular bar 121 to slide into the second rectangular bar 12 through the rectangular block 241, and drives the U-shaped frame 1 to move closer to the ground. The U-shaped frame 1 drives the bevel block 14 close to the ground. After the bevel block 14 approaches the ground, it drives the second cylinder 142 to slide into the first cylinder 141, so that the spiral conveying piece 151 extends into the ground to loosen the soil. The depth of the spiral conveying piece 151 extending into the ground can be accurately controlled by driving the screw 22.

[0045] like Figure 5 As shown, handles 23 are respectively provided on both sides of the upper end of the fifth rectangular plate 2 described in this embodiment.

[0046] Specifically, similar handles 23 are provided on both sides of the fifth rectangular plate 2, so that after the loosening device is turned around, it is convenient to push the loosening device in two directions.

[0047] Embodiment 2: Figure 2 As shown, compared with Example 1, another implementation of the present invention is: an eighth rectangular bar 132 is fixedly connected between the first rectangular plates 131 , and a plurality of first arc blocks 133 are fixedly connected to the lower end of the eighth rectangular bar 132 .

[0048] Specifically, after the soil is dug out, the soil becomes loose after screening and crushing and falls back to the ground. A row of first arc blocks 133 provided at the lower end of the eighth rectangular strip 132 can smooth the loosened soil to facilitate subsequent planting.

[0049] Working principle: push the handle 23 to drive the wheel 122 to rotate, the U-shaped frame 1 is placed on the ground, the second cylinder 142 contacts the ground, and then drives the screw rod 22 to rotate, drives the fifth rectangular plate 2 to move upward through the ring 21, and drives the seventh rectangular bar 24 to move upward at the same time. The seventh rectangular bar 24 drives the third rectangular bar 121 to slide into the second rectangular bar 12 through the rectangular block 241, drives the U-shaped frame 1 to move closer to the ground, and the U-shaped frame 1 drives the bevel block 14 close to the ground. After the bevel block 14 is close to the ground, it drives the second cylinder 142 to slide into the first cylinder 141, so that the spiral conveying piece 151 extends into the ground to loosen the soil. The depth of the spiral conveying piece 151 extending into the ground can be accurately controlled by driving the screw rod 22;

[0050] After the depth is adjusted, the first cylindrical rod 15 is driven to drive the spiral conveying piece 151 to rotate. The first cylindrical rod 15 rotates toward the inside of the land. The spiral conveying piece 151 transports the soil upward when it rotates, and then the soil falls into the inside of the bevel block 14. At the same time, the handle 23 is pushed to drive the U-shaped frame 1 to move. In the process of the soil falling into the bevel block 14, a hook is provided at the end of the third arc bar 161. The rotating third arc bar 161 hooks out the plastic bag and weeds in the soil, and the remaining soil falls to the ground through the second rectangular hole 17. By rotating the third arc bar 161, the weeds and plastic bag in the soil can be hooked out while loosening the soil. When the third arc bar 161 hooks out the plastic bag and weeds After the grass is hooked out, it continues to rotate, and then passes between the second arc strips 1446. The third arc strips 161 slide between the second arc strips 1446, leaving the plastic bag and the weeds on the upper end of the second arc strips 1446. When there are too many plastic bags and weeds on the upper end of the second arc strips 1446, they need to be taken out in time. At this time, the T-shaped slider 1441 is driven to slide in the first rectangular hole 144 toward the side close to the third arc strip 161, and the first spring 1442 is squeezed. At the same time, the second arc strip 1446 slides upward along the second cylindrical rod 16, and drives the sixth rectangular strip 1445 to slide to the inside of the fifth rectangular strip 1444, and then the cover plate 145 is opened to take out the plastic bag and the weeds.

[0051] The soil without the plastic bag and weeds falls into the lower end of the bevel block 14, and the third cylindrical rod 171 is driven to rotate to drive the extrusion block 172 to rotate. The extrusion blocks 172 on both sides rotate at the same time to further crush the soil, making the soil softer.

[0052] After planting for a period of time, the nutrients in the soil are gradually lost. During planting, the soil needs to be fertilized regularly. When using the present invention, fertilizer is put into one side of the second rectangular plate 18 inside the bevel block 14. When the third cylindrical rod 171 rotates to drive the extrusion block 172 to rotate, the extrusion block 172 rotates to push the fourth rectangular plate 182 upward, and the fourth rectangular plate 182 drives the third rectangular plate 181 to slide inside the second rectangular plate 18. The third rectangular plate 181 is lifted upward, and the fertilizer flows out from under the third rectangular plate 181 and mixes in the soil. The fertilizer and the soil are fully mixed through the rotation of the extrusion block 172, and then fall to the ground.

[0053] When it moves to one side of the greenhouse and needs to turn around, the rectangular slider 33 is driven to slide in the rectangular groove 31 and squeeze the second spring 331, and then the rectangular slider 33 is driven to rotate. The rectangular slider 33 drives the second cylindrical block 32 to rotate 180 degrees through the first cylindrical block 3, so that the circular plate 332 rotates at the upper end of the U-shaped frame 1, and then the circular plate 332 is located on both sides of the U-shaped frame 1. Then the second spring 331 releases the elastic force, pushing the rectangular slider 33 to drive the circular plate 332 to be close to both sides of the U-shaped frame 1. At this time, the U-turn is completed, and the translation device pushes the handle 23 on the other side to continue loosening the soil.
