Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse roof cleaning equipment, in particular to a track device and roof cleaning equipment applied to a multi-span greenhouse roof cleaning machine. Background Art

[0002] Multi-span greenhouses, especially Venlo multi-span greenhouses, are mainly used for seedling cultivation, planting crops such as vegetables and flowers. The growth and development of crops requires sufficient sunlight. The roof of the multi-span greenhouse is easily polluted by dust, especially in the northern part of China, where there is a lot of floating dust in the air, which is easy to accumulate on the roof, making the roof of the multi-span greenhouse dirty and reducing the light transmittance of the roof, thus affecting the growth of crops, resulting in reduced crop yields and quality. Therefore, it is very important to keep the roof of the multi-span greenhouse clean and improve the light transmittance of the multi-span greenhouse.

[0003] The multi-span greenhouse has a large area and is divided into many roofs, which are connected as a whole through gutters. If manual cleaning is adopted, not only the workload and work intensity are large, the efficiency is low, the cleaning is uneven, and water resources are wasted, but there are also personal safety issues. At present, roof cleaning machines are usually used to clean the roofs of multi-span greenhouses. During cleaning, the roof cleaning machine straddles a single roof of the multi-span greenhouse, moves forward, backward and sprays water in the direction of the gutter, thereby cleaning a single multi-span greenhouse roof. Since the roof cleaning machine can only move in the direction of the gutter, after cleaning a single multi-span greenhouse roof, the roof cleaning machine needs to be transferred to the adjacent roof through a transfer platform to clean the adjacent roof. The transfer platform can accommodate the roof cleaning machine, and use the track at the end of the multi-span greenhouse gutter and the ring beam or steel pipe at the bottom of the gable of the multi-span greenhouse to move along the gable direction of the multi-span greenhouse to transfer the roof cleaning machine to different roof positions of the multi-span greenhouse. The roof cleaning machine needs to be transferred once for each roof cleaned, and this cycle is repeated to eventually complete the cleaning operation of all roofs of the multi-span greenhouse.

[0004] As a natural phenomenon, the steel structure of a multi-span greenhouse will expand or contract due to heat expansion and contraction. When the multi-span greenhouse is large and the gable is long, the steel structure of the greenhouse will stretch or shorten due to heat expansion and contraction. When the deformation exceeds a certain design value, it will affect the use function and structural safety of the multi-span greenhouse. Therefore, it is necessary to divide the greenhouse into different zones during the plan layout. By setting deformation joints at the partition positions of the multi-span greenhouse, the multi-span greenhouses in different zones are connected as a whole. Similarly, the tracks used for the operation of the roof cleaning machine and the transfer platform will also stretch or shorten due to heat expansion and contraction. If the tracks for the operation of the roof cleaning machine and the transfer platform are very long, the deformation will also be large. When a fixed connection is used, a large internal force will be generated, resulting in twisting and deformation, causing safety hazards. Therefore, the tracks for the operation of the roof cleaning machine and the transfer platform also need to be disconnected, but the roof cleaning machine and the transfer platform are difficult to transfer freely between the disconnected tracks, and cannot reach the roofs of different zones of the multi-span greenhouse, so it is impossible to clean the roof of the multi-span greenhouse on both sides of the deformation joint.

[0036] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Combine the following Figures 1 to 5 , the track device applied to the multi-span greenhouse roof cleaning machine provided by the embodiment of the utility model is described in detail through specific embodiments and application scenarios.

[0038] First, as Figure 1 and Figure 3 As shown, the present embodiment provides a track device 11 for use in a multi-span greenhouse roof cleaning machine, comprising: a first track 111 , a second track 112 and a transition track 113 .

[0039] The first track 111 and the second track 112 are respectively arranged on both sides of the deformation joint of the multi-span greenhouse 2 and are arranged along the gable direction of the multi-span greenhouse 2 at fixed intervals.

[0040] A first end of the transition track 113 is fixedly connected to the first track 111 , and a second end of the transition track 113 is slidably connected to the second track 112 .

[0041] It is understandable that the first rail 111 and the second rail 112 are arranged on the outer side of the gable of the multi-span greenhouse 2. In order to avoid the adverse effects caused by thermal expansion and contraction of the steel structure of the multi-span greenhouse 2 and the first rail 111 and the second rail 112, a gap is provided between the first rail 111 and the second rail 112 so that when the first rail 111 and the second rail 112 are elongated and shortened, the gap between the first rail 111 and the second rail 112 can absorb the deformation, thereby avoiding the first rail 111 and the second rail 112 from twisting and deforming to cause safety hazards.

[0042] When the transfer platform 13 moves along the gable direction of the multi-span greenhouse 2, the wheels of the transfer platform 13 (not shown in the figure) move along the first track 111 or the second track 112, and need to transfer freely between the first track 111 or the second track 112. Since the first track 111 and the second track 112 are provided with a gap and are in a disconnected state, a transition track 113 needs to be provided between the first track 111 and the second track 112 to ensure that the wheels of the transfer platform 13 are not suspended in the air and can transfer freely between the first track 111 and the second track 112.

[0043] The first end of the transition track 113 is fixedly connected to the first track 111, so that the first track 111 provides an installation support for the transition track 113, and the second end of the transition track 113 is slidably connected to the second track 112, so that although the first track 111 and the second track 112 are physically connected through the transition track 113, the wheels of the transfer platform 13 will not be suspended when passing through the gap between the first track 111 and the second track 112, and can be freely transferred between the first track 111 and the second track 112, and the relative movement between the first track 111 and the second track 112 is not restricted, thereby leaving an adjustable length for the change of the relative distance between the first track 111 and the second track 112.

[0044] Specifically, the transition track 113 and the first track 111 can be connected by a bolt pair, a pin connection, or other forms of detachable connection. Any connection method limits the transition track 113, and relative movement is not allowed between the transition track 113 and the first track 111 in the extension direction of the first track 111; the transition track 113 and the second track 112 are connected by a sliding connection, and relative movement is allowed between the transition track 113 and the second track 112 in the extension direction of the second track 112.

[0045] The first track 111 and the second track 112 may be made of rectangular tubes, and the transition track 113 may be made of U-shaped cross-section profiles or rectangular tubes.

[0046] The track device 11 for a multi-span greenhouse roof cleaning machine provided by the utility model is provided by arranging the first track 111 and the second track 112 at intervals on both sides of the deformation joint of the multi-span greenhouse 2, arranging a transition track 113 between the first track 111 and the second track 112, and making the first track 111 and the transition track 113 fixedly connected, and the second track 112 and the transition track 113 slidably connected, so that the first track 111 and the second track 112 can realize continuous arrangement of the track surface through the transition track 113, so that the wheels of the transfer platform 13 will not be suspended when passing through the gap between the first track 111 and the second track 112, thereby realizing the first track 1 The first track 111 and the second track 112 can be freely transferred between them, ensuring the safe operation of the roof cleaning machine and the transfer platform 13. At the same time, when the first track 111 and the second track 112 expand and contract due to thermal expansion and contraction, the first track 111 and the second track 112 can also rely on the sliding connection between the second track 112 and the transition track 113 to achieve relative movement of the first track 111 and the second track 112, so that the first track 111 and the second track 112 will not be twisted and deformed due to the dimensional changes caused by the thermal expansion and contraction of the steel structure of the multi-span greenhouse 2 and the first track 111 and the second track 112 themselves, thereby ensuring the safety and reliability of the operation of the roof cleaning machine 12 and the transfer platform 13 in different environments.

[0047] In some embodiments, Figure 1 and Figure 2 As shown, two ends of the transition track 113 of this embodiment are respectively inserted into the first track 111 and the second track 112 .

[0048] It is understandable that the cross-sectional dimensions of the transition track 113 of the present embodiment are smaller than the cross-sectional dimensions of the first track 111 and the second track 112 , so that both ends of the transition track 113 can extend into the first track 111 and the second track 112 , respectively.

[0049] In practical applications, the top surfaces of the first track 111 and the second track 112 are usually set to be flush, and the top surface of the transition track 113 is in contact with the inner sides of the top surfaces of the first track 111 and the second track 112. The height difference between the top surface of the transition track 113 and the top surface of the first track 111 is equal to the wall thickness of the first track 111 or the second track 112. This height is usually 4 to 6 mm and does not affect the slow movement of the transfer platform 13.

[0050] In this embodiment, the two ends of the transition track 113 are respectively inserted into the first track 111 and the second track 112, so that the transition track 113 and the second track 112 can slide relative to each other through the top surface of the transition track 113 and the inner side surface of the top surface of the second track 112. The structure is simple and easy to construct.

[0051] In some embodiments, Figure 1 and Figure 2 As shown, the second rail 112 of this embodiment is provided with a first fastener 116 .

[0052] The first fastener 116 abuts against the bottom of the second end of the transition rail 113 to lift the second end of the transition rail 113 .

[0053] It is understandable that when the first track 111 and the transition track 113 are fixedly connected, the first track 111 provides a first force application point for the transition track 113, and the first fastener 116 of the present embodiment can provide a second force application point for the transition track 113, so that both ends of the transition track 113 are subjected to force, and when the transition track 113 moves relative to the second track 112, the first fastener 116 lifts the transition track 113, so that the transition track 113 always moves in the same direction as the extension direction of the second track 112, ensuring that the second end of the transition track 113 will not undergo flexural deformation or downward deformation, thereby ensuring the stability and reliability of the relative sliding of the transition track 113 and the second track 112.

[0054] Specifically, the first fastener 116 may be a bolt pair, or a pin, or other forms of detachable connection.

[0055] In some embodiments, the transition track 113 of this embodiment is a U-shaped cross-section profile.

[0056] It is understandable that the cross-sectional dimensions of the U-shaped cross-sectional profile of this embodiment are smaller than the cross-sectional dimensions of the first track 111 and the second track 112 , and the top surface of the U-shaped cross-sectional profile fits the inner sides of the first track 111 and the second track 112 .

[0057] In this embodiment, the transition track 113 is configured as a U-shaped cross-section profile, which is easy to obtain locally, convenient to install, low in cost, and good in economy.

[0058] In some embodiments, the transition track 113 of this embodiment is a rectangular tube.

[0059] It is understandable that the cross-sectional dimensions of the rectangular tube in this embodiment are smaller than the cross-sectional dimensions of the first track 111 and the second track 112 , and the top surface of the rectangular tube fits with the inner sides of the first track 111 and the second track 112 .

[0060] In this embodiment, the transition track 113 is configured as a rectangular tube, which is easy to obtain from local materials, convenient to install, and low in cost.

[0061] In some embodiments, Figure 3 and Figure 4 As shown, two ends of the transition track 113 of this embodiment are overlapped on the outer sides of the tops of the first track 111 and the second track 112 respectively.

[0062] It is understandable that the horizontal cross-sectional dimensions of the U-shaped cross-sectional profile of this embodiment are greater than the horizontal cross-sectional dimensions of the first track 111 and the second track 112 , and the transition track 113 of this embodiment is overlapped on the outer sides of the tops of the first track 111 and the second track 112 .

[0063] In practical applications, the top surfaces of the first track 111 and the second track 112 are usually set to be flush, and the top surface of the transition track 113 is in contact with the outer sides of the top surfaces of the first track 111 and the second track 112. The height difference between the top surface of the transition track 113 and the top surface of the first track 111 or the second track 112 is equal to the wall thickness of the transition track 113, and this height is usually 4 to 6 mm, which does not affect the slow movement of the transfer platform 13.

[0064] In this embodiment, the two ends of the transition track 113 are overlapped on the outer sides of the tops of the first track 111 and the second track 112 respectively, so that the transition track 113 and the second track 112 can slide relative to each other through the inner side of the top surface of the transition track 113 and the outer side of the top surface of the second track 112. The structure is simple and easy to construct.

[0065] In some embodiments, Figure 3 and Figure 4 As shown, the transition track 113 of this embodiment is a U-shaped cross-section profile, including a first side plate 1131 , a second side plate 1132 and a connecting plate 1133 .

[0066] The first side plate 1131 and the second side plate 1132 are respectively arranged perpendicularly to the two sides of the connecting plate 1133, and the two ends of the connecting plate 1133 are respectively attached to the top surfaces of the first track 111 and the second track 112, and the first track 111 and the second track 112 are both sandwiched between the first side plate 1131 and the second side plate 1132.

[0067] It is understandable that a clamping space is formed between the first side plate 1131, the second side plate 1132 and the connecting plate 1133. When the transition track 113 and the second track 112 slide relative to each other, the clamping space can guide the transition track 113 to move relative to each other along the inner sides of the first side plate 1131 and the second side plate 1132, and limit the relative movement of the transition track 113, thereby ensuring the reliability and stability of the movement of the transition track 113.

[0068] In some embodiments, Figures 1 to 4 As shown, the transition track 113 of this embodiment includes a first track bracket 114 and a second track bracket 115 .

[0069] The first track 111 is connected to the gable column or the gutter of the multi-span greenhouse 2 through the first track bracket 114 , and the second track 112 is connected to the gable column or the gutter of the multi-span greenhouse 2 through the second track bracket 115 .

[0070] It is understandable that the first track bracket 114 and the second track bracket 115 are both mounted on the gable columns or the gutter of the multi-span greenhouse 2, the first track bracket 114 provides an installation support for the first track 111, and the second track bracket 115 provides an installation support for the second track 112, to ensure that when the transfer platform 13 travels on the first track 111 and the second track 112, the first track 111 and the second track 112 have a sufficient number of support points to bear the weight of the roof cleaning machine 12 and the transfer platform 13 without deformation.

[0071] In some embodiments, Figures 1 to 4 As shown, the first track 111 and the transition track 113 of this embodiment are fixedly connected by a second fastener 117 .

[0072] It is understandable that the second fastener 117 fixes the first track 111 and the transition track 113, and the first track 111 and the transition track 113 cannot move relative to each other. The second fastener 117 is easy to install, inexpensive, and easy to obtain locally. When the transition track 113 is repaired or replaced later, the second fastener 117 is easy to disassemble.

[0073] Specifically, the first fastener 116 may be a bolt pair, or a pin, or other forms of detachable connection.

[0074] In some embodiments, Figure 5 As shown, the transition track 113 of this embodiment can be provided in plurality according to the multi-span greenhouse 2 being divided into a plurality of partitions due to thermal expansion and contraction of the steel structure.

[0075] A plurality of transition tracks 113 are arranged at deformation joints of the multi-span greenhouse 2 along the gable direction of the multi-span greenhouse 2 , and a first track 111 and a second track 112 are arranged on both sides of the plurality of transition tracks 113 .

[0076] It is understandable that when the length of the gable direction of the multi-span greenhouse 2 is very long, multiple first rails 111 and multiple second rails 112 can be set along the gable direction of the multi-span greenhouse 2, and multiple transition rails 113 can be set between the multiple first rails 111 and the multiple second rails 112. In this way, there are multiple gaps along the gable direction of the multi-span greenhouse 2, and the multiple gaps can ensure that the longer track surface absorbs a larger amount of expansion and contraction deformation.

[0077] In a second aspect, in some embodiments, as Figure 5 As shown, this embodiment provides a roof cleaning device 1, including: a roof cleaning machine 12, a transfer platform 13 and a track device 11.

[0078] The transfer platform 13 is movably arranged on the track device 11, and the roof cleaning machine 12 is used to clean the roof of the multi-span greenhouse.

[0079] The roof cleaning machine 12 can be stored in the transfer platform 13; the roof cleaning machine 12 moves along the track device 11 along the transfer platform 13 so as to switch to another greenhouse partition to be cleaned.

[0080] Specifically, since the roof cleaning equipment 1 includes a track device 11, and the specific structure of the track device 11 refers to the above embodiment, the roof cleaning equipment 1 shown in this embodiment includes all the technical solutions of the above embodiment, and therefore, at least has all the beneficial effects achieved by all the technical solutions of the above embodiment, which will not be repeated here one by one.

[0081] It is understandable that the multi-span greenhouse 2 includes many roofs, and the roof cleaning machine 12 can ride on a single roof of the multi-span greenhouse 2 to move forward, backward and spray water to clean the roof. When the roof cleaning machine 12 is transferred between the roofs of different multi-span greenhouses 2, the roof cleaning machine 12 runs from the roof of the multi-span greenhouse 2 to the transfer platform 13, and the transfer platform 13 moves on the track device 11 to transfer the roof cleaning machine 12 to the adjacent roof position. Then, the roof cleaning machine 12 runs from the transfer platform 13 to the adjacent roof of the multi-span greenhouse 2, thereby completing the cleaning operation of all roofs of the multi-span greenhouse 2.

[0082] In this embodiment, the track device 11 enables the roof cleaning machine 12 to be transferred between different partitioned roofs of the multi-span greenhouse 2 via the transfer platform 13, so that the roof cleaning machine 12 can clean all the roofs of the multi-span greenhouse 2.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
