Description

Technical Field

[0001] The invention relates to the technical field of greenhouses, in particular to a supporting profile for installing a greenhouse. Background Art

[0002] A greenhouse is a structure used to grow crops or protect the growth of plants. It usually consists of a frame made of metal or plastic and a transparent covering material such as glass, polycarbonate sheets, polyethylene film, etc.

[0003] The patent with announcement number CN211314760U relates to the technical field of aluminum profiles, and discloses an aluminum profile for greenhouses, including an aluminum profile body, the left and right sides of the aluminum profile body are integrally formed with docking parts, and the top of the aluminum profile body is integrally formed with a clamping part. This patent fixes the aluminum profile body by sleeve-mounting it on other tubular brackets, and then uses the docking parts set on the left and right sides of the aluminum profile body to insert other horizontally built support tubes for fixation. The clamping part on the top of the aluminum profile body is convenient for clamping with the support rod, which facilitates the greenhouse. The T-slot on the positioning rod is used to facilitate the docking between pipes, improve the fit, and reduce the shaking gap. Then the bolts are used to penetrate the pipes, and the fixed through holes and the empty slots are used to extend to the other side of the pipes, thereby improving the fixation between the structures, increasing the firmness, and improving the reliability and safety of the greenhouse. However, when this device is used to fix the arched frame, the docking port of the device is difficult to fit into the frame that needs to be installed at an angle, resulting in limited installation and poor practicality. Therefore, a supporting profile for greenhouse installation is proposed to solve the above-mentioned problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a supporting profile for installing a greenhouse in view of the deficiencies in the above-mentioned prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a supporting profile for installing a greenhouse, including a fixing block, and also including:

[0006] An adjusting device, used for adjusting the angle when the greenhouse frame is installed tilted, and the adjusting device is arranged on the inner wall of the fixing block;

[0007] A support device, used to automatically adjust the angle at which the support member is driven into the soil according to the inclination angle of the greenhouse frame, and the support device is arranged on the inner wall of the fixed block;

[0008] A cutting device, used for cutting or breaking roots or hard soil blocks in the soil, wherein the cutting device is arranged inside the supporting device;

[0009] The inner wall of the fixing block is fixedly connected with a support column, and the inner wall of the support column is threadedly connected with a fixing screw;

[0010] The adjusting device comprises a mounting block, a transmission rod, a limiting block, a telescopic rod, a limiting hole and a transmission plate, wherein the mounting blocks are provided in plurality, and the plurality of mounting blocks are rotatably connected to the inner wall of the fixed block, and the plurality of mounting blocks are in contact with each other, the transmission rod is rotatably connected to the inner wall of the fixed block, and the inner wall of each mounting block is provided with two limiting rings, one end of the telescopic rod is fixedly connected to the limiting ring surface inside one mounting block, and the other end of the telescopic rod is fixedly connected to the limiting ring surface inside the other mounting block, the limiting hole is provided on the inner wall of the mounting block, and the transmission plate is fixedly connected to the bottom of the left side of the mounting block; the surface of the transmission rod is provided with a plurality of bidirectional threads, and the bidirectional threads are threadedly connected to the inner wall of the limiting ring, the surface of the transmission rod is in contact with the inner wall of the mounting block, the surface of the limiting block is in contact with the inner wall of the limiting hole, and the fixing is performed by fixing the screw The block is fixed in the ground, and then the frame of the greenhouse is installed in the mounting block and fixed with screws to achieve fixed support of the greenhouse frame. Before installing the frame, rotate the transmission rod, and the transmission rod drives the two limit rings to rotate in the opposite direction through the bidirectional thread on the surface, but the two limit rings cannot rotate because they are limited by the telescopic rod. Therefore, the two limit rings can be driven to gather or separate through the thread. When the two limit rings gather, the limit blocks on the surfaces of the limit rings will leave the limit holes on the inner walls of the mounting block. At this time, the mounting block can be rotated and adjusted to the angle where the inclined frame or arched frame needs to be installed, and the transmission rod is rotated in the opposite direction again to make the two limit rings move in the opposite direction and drive the limit blocks to insert into the limit holes, so that the mounting block is fixed and limited, thereby the angle of the mounting block can be adjusted, which is convenient for fixed installation of greenhouse frames with different inclination angles, thereby improving the scope of application of the device.

[0011] Preferably, the support device comprises a rotating block, a fixed plate, a guide block and a support plate, the rotating block is rotatably connected to the inner wall of the fixed block by a torsion spring, the fixed plate is fixedly connected to the inner wall of the rotating block, the guide block is fixedly connected to the right side of the fixed plate, and the support plate is slidably connected to the inner wall of the fixed plate; the support device also includes a support rod and a stopper, the support rod is rotatably connected to the inner wall of the support plate by a torsion spring, and the stopper is fixedly connected to the inner wall of the support plate; the lower surface of the guide block is in contact with the upper surface of the transmission plate, and the bottom of the stopper is in contact with the top of the support rod after rotation. When the device is installed to tilt the frame, the mounting block will rotate and adjust, and when the mounting block rotates, the transmission plate is driven to rotate, and the transmission plate pushes the guide block to move, and the guide block drives the fixed plate and the rotating block to rotate, and the fixed plate drives the supporting plate to rotate after rotation, and the rotated supporting plate is driven into the soil by workers. When the frame is installed with a larger inclination angle of the mounting block, the angle at which the support plate rotates toward the mounting block will be larger. When the frame is installed in the mounting block with an inclination to the right, the frame will use the contact surface between the fixed block and the ground as the center of the circle to apply a rotational force to the fixed block, rather than the vertical pressure when the frame is installed vertically. Therefore, the support plate rotates toward the mounting block and is driven into the soil, which can improve the stability of the fixed block, so that there is more soil on the left side of the support plate, thereby increasing the firmness of the support plate. At the same time, when the support plate moves down, it drives the support rod to move out of the fixed plate. At this time, the fixed plate will no longer block the support rod, and the support rod will rotate out of the support plate under the action of the torsion spring. At this time, when the support plate is driven into the soil, the support rod will rotate out and insert into the soil while the support plate is driven into the soil. The block will limit the support rod after it has rotated to a certain angle to prevent it from continuing to rotate and becoming difficult to insert into the soil. The insertion of the support rod into the soil can further increase the contact area between the support plate and the soil, thereby improving the stability of the device.

[0012] Preferably, the cutting device includes a left cutting plate, saw teeth and a guide groove, the left cutting plate is slidably connected to the inner wall of the support plate, the saw teeth are arranged at the bottom of the left cutting plate, and the guide groove is arranged on the surface of the left cutting plate; the cutting device also includes a guide rod, a support block and a right cutting plate, the right cutting plate is slidably connected to the inner wall of the support plate, the guide rod is slidably connected to the inner wall of the support plate, and the support block is fixedly connected to both ends of the guide rod; the saw teeth are arranged at the bottom of the right cutting plate, and the guide groove is arranged on the surface of the right cutting plate, the guide groove on the surface of the right cutting plate is in the opposite direction to the guide groove on the surface of the left cutting plate, and the surface of the guide rod is respectively aligned with the guide groove on the surface of the right cutting plate and The guide groove on the surface of the left cutting plate contacts the support plate. When the support plate moves downward, it will drive the support block to move downward, and the support block will contact the top of the soil and push the support block upward in the opposite direction. At this time, the support plate continues to move downward and drives the left and right cutting plates to move downward together, and the support block drives the guide rod to move upward, and the guide rod will move in the guide grooves in the left and right cutting plates. The left and right cutting plates can be driven to gather and separate reciprocally through the guidance of the guide groove, so that the left and right cutting plates move relative to each other and the roots and stems in the soil are cut off through the saw teeth to prevent the presence of some roots and stems in the soil from affecting the insertion of the support plate. At the same time, the saw teeth can also crush the hard soil blocks, so that the support plate can be more easily inserted into the soil.

[0013] The present invention adopts the above technical solution to bring the following beneficial effects:

[0014] 1. The supporting profile for installing the greenhouse is fixed in the ground through the cooperation of the fixing block, the supporting column, the fixing screw, the mounting block, the transmission rod, the limiting ring, the limiting block, the telescopic rod, the limiting hole and the transmission plate. Then the frame of the greenhouse is installed in the mounting block and fixed by screws to achieve fixed support of the greenhouse frame. The mounting block can be rotated and adjusted to the angle where the inclined frame or the arched frame needs to be installed. The angle of the mounting block can be adjusted, which is convenient for fixing and installing the greenhouse frames with different inclination angles, thereby improving the scope of application of the device.

[0015] 2. The supporting profile for installing the greenhouse works through the cooperation between the rotating block, the fixed plate, the guide block, the support plate, the support rod and the stopper. When the device is installing the inclined frame, the mounting block will rotate and adjust. When the mounting block rotates, it drives the transmission plate to rotate, and the transmission plate pushes the guide block to move. The guide block drives the fixed plate and the rotating block to rotate. After the fixed plate rotates, it drives the support plate to rotate. The rotated support plate is driven into the soil by workers. At this time, when the mounting block is installed with a larger inclination angle of the frame, the angle of rotation of the support plate toward the mounting block is greater. When the frame is installed to the right in the mounting block, the frame will use the contact surface between the fixed block and the ground as the center of the circle to apply a rotational force to the fixed block instead of the vertical pressure when the frame is installed vertically. Therefore, the support plate rotates toward the mounting block and is driven into the soil to improve the stability of the fixed block, so that there is more soil on the left side of the support plate, thereby increasing the firmness of the support plate.

[0016] 3. The supporting profile for installing the greenhouse cooperates with the left cutting plate, saw teeth, guide grooves, guide rods, support blocks, and right cutting plates. When the support plate moves downward, the support block will move downward, and the support block will contact the top of the soil and push the support block upward in the opposite direction. At this time, the support plate continues to move downward and drives the left cutting plate and the right cutting plate to move downward together, and the support block drives the guide rod to move upward. The guide rod will move in the guide grooves in the left cutting plate and the right cutting plate. The left cutting plate and the right cutting plate can be driven to gather and separate reciprocatingly through the guidance of the guide grooves, so that the left cutting plate and the right cutting plate move relative to each other and the roots and stems in the soil are cut off through the saw teeth to prevent the presence of some roots and stems in the soil from affecting the insertion of the support plate. At the same time, the saw teeth can also crush the hard soil blocks, so that the support plate can be more easily inserted into the soil. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figure 1-Figure 8 One embodiment of the present invention is: a supporting profile for installing a greenhouse, comprising a fixing block 1, and also comprising:

[0028] An adjusting device 4 is used for adjusting the angle when the greenhouse frame is installed tilted, and the adjusting device 4 is arranged on the inner wall of the fixing block 1;

[0029] A support device 5, used to automatically adjust the angle at which the support member is driven into the soil according to the inclination angle of the greenhouse frame, and the support device 5 is arranged on the inner wall of the fixed block 1;

[0030] A cutting device 6, used for cutting or breaking roots or hard soil blocks in the soil, and the cutting device 6 is arranged inside the supporting device 5;

[0031] The inner wall of the fixing block 1 is fixedly connected with a support column 2, and the inner wall of the support column 2 is threadedly connected with a fixing screw 3; the adjusting device 4 includes a mounting block 41, a transmission rod 42, a limit block 44, a telescopic rod 45, a limit hole 46 and a transmission plate 47. The fixing block 1 is fixed to the ground by the fixing screw 3, and then the frame of the greenhouse is installed in the mounting block 41 and fixed by screws to achieve fixed support of the greenhouse frame. The number of mounting blocks 41 is set to multiple, and the multiple mounting blocks 41 are rotatably connected to the inner wall of the fixing block 1. The plurality of mounting blocks 41 are in contact with each other, the transmission rod 42 is rotatably connected to the inner wall of the fixed block 1, and the inner wall of each mounting block 41 is provided with two limiting rings 43, one end of the telescopic rod 45 is fixedly connected to the surface of the limiting ring 43 inside one mounting block 41, and the other end of the telescopic rod 45 is fixedly connected to the surface of the limiting ring 43 inside another mounting block 41, and the limiting hole 46 is provided on the inner wall of the mounting block 41, and the transmission plate 47 is fixedly connected to the bottom of the left side of the mounting block 41. Before installing the frame, the rotating transmission rod 42 The transmission rod 42 drives the two limit rings 43 to rotate in the opposite direction through the bidirectional threads on the surface, but the two limit rings 43 are limited by the telescopic rod 45 and cannot rotate. Therefore, the two limit rings 43 can be brought together or separated by the threads. When the two limit rings 43 are brought together, the limit blocks 44 on the surfaces of the limit rings 43 will leave the limit holes 46 on the inner wall of the mounting block 41. At this time, the mounting block 41 can be rotated and adjusted to the angle where the inclined frame or arched frame needs to be installed, and the transmission rod 42 is rotated in the opposite direction again, so that The two limit rings 43 move in opposite directions and drive the limit block 44 to insert into the limit hole 46, so that the mounting block 41 is fixed and limited, so that the angle of the mounting block 41 can be adjusted, which is convenient for the fixed installation of greenhouse frames with different inclination angles, and improves the application range of the device; a plurality of bidirectional threads are provided on the surface of the transmission rod 42, and the bidirectional threads are threadedly connected with the inner wall of the limit ring 43, the surface of the transmission rod 42 is in contact with the inner wall of the mounting block 41, and the surface of the limit block 44 is in contact with the inner wall of the limit hole 46.

[0032] Working principle: fix the fixing block 1 in the ground by fixing the screw rod 3, then install the frame of the greenhouse into the mounting block 41 and fix it by screws, so as to realize the fixed support of the frame of the greenhouse. Before installing the frame, rotate the transmission rod 42, and the transmission rod 42 drives the two limit rings 43 to rotate in the opposite direction through the bidirectional thread on the surface, but the two limit rings 43 are limited by the telescopic rod 45 and cannot rotate, so the two limit rings 43 can be driven to gather or separate through the thread. When the two limit rings 43 gather together, the limit block 44 on the surface of the limit ring 43 will leave the limit hole 46 on the inner wall of the mounting block 41. At this time, the mounting block 41 can be rotated and adjusted to the angle where the inclined frame or arched frame needs to be installed, and the transmission rod 42 is rotated in the opposite direction again, so that the two limit rings 43 move in the opposite direction and drive the limit block 44 to insert into the limit hole 46, so that the mounting block 41 is fixed and limited, so that the angle of the mounting block 41 can be adjusted, which is convenient for fixing and installing the greenhouse frame with different inclination angles, thereby improving the scope of application of the device.

[0033] See also Figure 1-Figure 8On the basis of the above embodiment, in another embodiment of the present invention, the support device 5 includes a rotating block 51, a fixed plate 52, a guide block 53 and a support plate 54, the rotating block 51 is rotatably connected to the inner wall of the fixed block 1 through a torsion spring, the fixed plate 52 is fixedly connected to the inner wall of the rotating block 51, the guide block 53 is fixedly connected to the right side of the fixed plate 52, and the support plate 54 is slidably connected to the inner wall of the fixed plate 52; the support device 5 also includes a support rod 55 and a stopper 56, the support rod 55 is rotatably connected to the inner wall of the support plate 54 through a torsion spring The stopper 56 is fixedly connected to the inner wall of the support plate 54. When the device is installed with an inclined frame, the installation block 41 will rotate and adjust. When the installation block 41 rotates, it drives the transmission plate 47 to rotate. The transmission plate 47 pushes the guide block 53 to move. The guide block 53 drives the fixed plate 52 and the rotating block 51 to rotate. After the fixed plate 52 rotates, it drives the support plate 54 to rotate. The rotated support plate 54 is driven into the soil by workers. At this time, when the installation block 41 is installed with a larger tilt angle of the frame, the support plate 54 rotates toward the installation block 41. The larger the angle, when the frame is installed in the installation block 41 to the right, the frame will use the contact surface between the fixing block 1 and the ground as the center of the circle to apply a rotational force to the fixing block 1, rather than the vertical pressure when the frame is installed vertically. Therefore, the support plate 54 rotates toward the installation block 41 and drives into the soil, which can improve the stability of the fixing block 1, so that there is more soil on the left side of the support plate 54, and the firmness of the support plate 54 is increased; the lower surface of the guide block 53 contacts the upper surface of the transmission plate 47, and the bottom of the stopper 56 contacts the top of the support rod 55 after rotation. When the support plate 54 moves downward, it drives the support rod 55 out of the fixed plate 52. At this time, the fixed plate 52 will no longer block the support rod 55. The support rod 55 will rotate out of the support plate 54 under the action of the torsion spring. At this time, when the support plate 54 is driven into the soil, the support rod 55 will rotate out and insert into the soil. The stopper 56 will limit the support rod 55 after it has rotated to a certain angle to prevent it from continuing to rotate and becoming difficult to insert into the soil. The insertion of the support rod 55 into the soil can further increase the contact area between the support plate 54 and the soil, thereby improving the stability of the device.

[0034] The cutting device 6 includes a left cutting plate 61, a sawtooth 62 and a guide groove 63. The left cutting plate 61 is slidably connected to the inner wall of the support plate 54. The sawtooth 62 is arranged at the bottom of the left cutting plate 61. The guide groove 63 is arranged on the surface of the left cutting plate 61. The cutting device 6 also includes a guide rod 64, a support block 65 and a right cutting plate 66. The right cutting plate 66 is slidably connected to the inner wall of the support plate 54. The guide rod 64 is slidably connected to the inner wall of the support plate 54. The support block 65 is fixedly connected to both ends of the guide rod 64. When the support plate 54 moves downward, the support block 65 will be driven to move downward. The support block 65 will contact the top of the soil and push the support block 65 upward in the opposite direction. At this time, the support plate 54 continues to move downward and drives the left cutting plate 61 and the right cutting plate 66 to move downward together, and the support block 65 drives the guide rod 64 to move upward. The sawtooth 62 is arranged at At the bottom of the right cutting plate 66, a guide groove 63 is provided on the surface of the right cutting plate 66, and the guide groove 63 on the surface of the right cutting plate 66 is in opposite directions to the guide groove 63 on the surface of the left cutting plate 61. The surface of the guide rod 64 contacts the guide groove 63 on the surface of the right cutting plate 66 and the guide groove 63 on the surface of the left cutting plate 61 respectively, and the guide rod 64 moves in the guide groove 63 in the left cutting plate 61 and the right cutting plate 66. The left cutting plate 61 and the right cutting plate 66 can be driven to gather and separate reciprocally through the guidance of the guide groove 63, so that the left cutting plate 61 and the right cutting plate 66 move relative to each other and the rhizomes in the soil are cut off through the saw teeth 62 to prevent the existence of some rhizomes in the soil from affecting the driving of the support plate 54. At the same time, the saw teeth 62 can also crush the hard soil blocks, so that the support plate 54 can be driven into the soil more easily.

[0035] Working principle: When the device is installing an inclined frame, the mounting block 41 will rotate and adjust. When the mounting block 41 rotates, it drives the transmission plate 47 to rotate. The transmission plate 47 pushes the guide block 53 to move. The guide block 53 drives the fixed plate 52 and the rotating block 51 to rotate. After the fixed plate 52 rotates, it drives the support plate 54 to rotate. The rotated support plate 54 is driven into the soil by workers. At this time, when the mounting block 41 is installed with a larger tilt angle of the frame, the support plate 54 rotates more toward the mounting block 41. When the frame is installed to the right in the mounting block 41, the frame will use the contact surface between the fixed block 1 and the ground as the center of the circle to apply a rotational force to the fixed block 1, rather than the vertical pressure when the frame is installed vertically. Therefore, the support plate 54 rotates toward the mounting block 41 and is driven into the soil, which can improve the stability of the fixed block 1, so that there is more soil on the left side of the support plate 54, thereby increasing the firmness of the support plate 54. At the same time, when the support plate 54 moves down, it drives the support rod 55 to move out of the fixed plate 52. At this time, the fixed plate 52 will no longer block the support rod 55, and the support rod 55 will rotate out of the support plate 54 under the action of the torsion spring. At this time, when the support plate 54 is driven into the soil, the support rod 55 will rotate out and insert into the soil, and the block 56 will limit the support rod 55 after it has rotated a certain angle to prevent it from continuing to rotate and becoming difficult to insert into the soil. The insertion of the support rod 55 into the soil can further increase the contact area between the support plate 54 and the soil, thereby improving the stability of the device.

[0036] When the support plate 54 moves downward, it will drive the support block 65 to move downward, and the support block 65 will contact the top of the soil and push the support block 65 upward in the opposite direction. At this time, the support plate 54 continues to move downward and drives the left cutting plate 61 and the right cutting plate 66 to move downward together, and the support block 65 drives the guide rod 64 to move upward, and the guide rod 64 will move in the guide groove 63 in the left cutting plate 61 and the right cutting plate 66. The left cutting plate 61 and the right cutting plate 66 can be driven to gather and separate reciprocally through the guidance of the guide groove 63, so that the left cutting plate 61 and the right cutting plate 66 move relative to each other and cut the roots and stems in the soil through the saw teeth 62, so as to prevent some roots and stems in the soil from affecting the driving of the support plate 54. At the same time, the saw teeth 62 can also crush the hard soil blocks, so that the support plate 54 can be driven into the soil more easily.
