Description

Technical Field

[0001] This invention relates to the field of agricultural equipment, and in particular to a glass greenhouse substrate tank cleaning machine. Background Technology

[0002] With the advancement of agricultural modernization, more and more regions are beginning to build large-scale modern agricultural greenhouse parks, showing a trend towards centralization and large-scale development. Soilless cultivation is gradually becoming popular in modern agricultural greenhouses, including various forms such as hydroponics and substrate cultivation. As the scale of planting increases and the number of planting facilities increases, the difficulty of greenhouse cleaning and disinfection is also increasing, resulting in huge labor costs.

[0003] A substrate trough is an irregularly shaped support structure that provides support and fixation for the crop substrate (usually coconut coir substrate) and collects the sap from the growing medium. The length of substrate troughs varies from tens to hundreds of meters. The typical crop growing cycle is 8-10 months. Prolonged placement and soaking in the sap will generate a large amount of dirt, moss, bacteria, etc. After the growing cycle ends, the substrate trough needs to be cleaned and disinfected to prepare for the next growing cycle. Because of its special irregular shape, cleaning the substrate trough is relatively difficult.

[0004] Currently, substrate tanks are mainly cleaned manually using high-pressure water guns, which is time-consuming, labor-intensive, wasteful of water, prone to dead spots, and inefficient. There is currently no automated cleaning device for substrate tanks in modern agricultural glass greenhouses. This patent relates to modern agricultural facilities and equipment, specifically a cleaning machine that can efficiently clean substrate tanks, effectively solving the aforementioned problems. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that the current method of cleaning substrate tanks relies on manual handheld high-pressure water guns, which is time-consuming, labor-intensive, wasteful of water resources, and prone to dead spots. Therefore, this invention proposes a glass greenhouse substrate tank cleaning machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A glass greenhouse substrate tank cleaning machine includes a water supply truck and a cleaner. The water supply truck supplies water to the cleaner, and the cleaner performs cleaning work along the substrate tank.

[0008] The cleaner includes a housing, legs, and clamping arms;

[0009] The shell has rollers at the bottom for moving on top of the substrate tank, and a high-pressure quick connector at the end of the shell for connecting to the water supply truck's water pipe; the shell also has a built-in water distribution pipe that connects to the high-pressure quick connector.

[0010] The shell has a support leg at each of the front and rear ends in the direction of movement. The support leg is a single-span structure, and the two span legs of the single-span structure are located on both sides of the substrate tank. A manifold is installed on the outside of the support leg. The manifold is similar to the support leg structure and is installed overlappingly. Several high-pressure nozzles for cleaning the substrate tank are distributed along the span structure on the manifold.

[0011] The bottom of the support leg is equipped with a rotating brush, which is located in the grooves on both sides of the substrate tank. Water outlet holes are distributed on the rotating brush.

[0012] The high-pressure nozzle and the water outlet are respectively connected to the water distribution pipe;

[0013] The clamping arms are a pair, located on both sides of the housing. Each clamping arm has a follower roller, and the clamping arms are clamped to both sides of the substrate groove by the follower roller.

[0014] As a further preferred embodiment, the cleaning machine also includes a limiting plate installed at the end of the substrate tank; a reversing valve is provided on the water distribution pipe inside the housing, and the water entering from the high-pressure quick connector is controlled by the reversing valve to enter the high-pressure nozzle and water outlet at the front end of the housing, or the high-pressure nozzle and water outlet at the rear end.

[0015] The reversing valve has a reversing handle located outside the housing. When the cleaner moves to the end of the substrate tank, the reversing handle strikes the limit plate, thereby switching the reversing valve.

[0016] As a further preferred option, the high-pressure nozzles on the manifold spray in an oblique direction away from the housing and towards the substrate tank, and the reaction force of the spray propels the cleaner to move on the substrate tank.

[0017] As a further preferred embodiment, the rotating brush rotates horizontally, with water outlets arranged circumferentially on the rotating brush and the spray direction of the water outlets being oblique. Through the reaction force of the spray, the rotating brush is in a rotating state.

[0018] As a further preferred option, the water supply vehicle includes a movable chassis with a water tank on the chassis. The end of the water tank has a hose reel with a water pipe wound around it. One end of the water pipe is connected to the water tank, and the other end is connected to a high-pressure quick connector.

[0019] As a further preferred option, the chassis has wheels.

[0020] As a further preferred option, the water tank is equipped with a water inlet connector, and the water inlet connector is equipped with a flow meter.

[0021] As a further preferred embodiment, the housing has a rotating seat on the side, and the end of the clamping arm is hinged to the rotating seat. A spring is provided between the spring buckle of the clamping arm near the middle position and the spring buckle of the rotating seat. When the clamping arm is clamping the substrate groove, the spring buckle of the clamping arm is lower than the spring buckle of the rotating seat. When the clamping arm is flipped up to release the clamping, the spring buckle of the clamping arm is higher than the spring buckle of the rotating seat.

[0022] As a further preferred option, the rotating base is provided with a limiting pin for fixing the clamping arm to maintain clamping and releasing clamping. Beneficial effects

[0023] This invention discloses a glass greenhouse substrate tank cleaning machine that minimizes manual intervention, provides a wide cleaning area, and ensures uniform rinsing. The cleaner relies on its own water source for automatic movement, with all water flow applied to the cleaning surface, resulting in water and energy savings, stable cleaning, faster speed, and applicability to various types of substrate tanks.

Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] A glass greenhouse substrate tank cleaning machine includes a water supply truck and a cleaner. The water supply truck supplies water to the cleaner, and the cleaner performs cleaning work along the substrate tank.

[0034] The water supply vehicle includes a movable chassis 101, on which is a water tank 103. The end of the water tank 103 has a hose reel 102, on which a water pipe is wound. One end of the water pipe is connected to the water tank 103, and the other end is connected to a high-pressure quick connector 202.

[0035] The chassis 101 has wheels.

[0036] The water tank 103 is equipped with a water inlet connector, and the water inlet connector is equipped with a flow meter 10.

[0037] The water supply truck provides water and pressure for the entire set of equipment. A high-pressure water pump is installed inside the chassis 101 to pump the clean water in the water tank 103 into the water pipe of the hose reel 102. When the cleaner moves forward or backward, the hose reel 102 simultaneously retracts and extends the high-pressure water pipe.

[0038] The vehicle body has no water tank 103 and does not store water itself. It relies on a retractable hose to connect to the on-site water source for water supply.

[0039] The cleaner includes a housing 201, legs 204, and clamping arms 208;

[0040] The housing 201 has a roller 203 at the bottom for moving on the top of the substrate tank, and a high-pressure quick connector 202 at the end of the housing 201 for connecting the water pipe of the water supply vehicle; the housing 201 has a built-in water distribution pipe that is connected to the high-pressure quick connector 202.

[0041] The housing 201 has a support leg 204 at each of its front and rear ends in the direction of movement. The support leg 204 is a single-span structure, with the two span legs of the single-span structure located on both sides of the substrate tank. A manifold 205 is installed on the outside of the support leg 204. The manifold 205 is similar in structure to the support leg 204 and is installed overlappingly. Several high-pressure nozzles 209 for cleaning the substrate tank are distributed along the span structure on the manifold 205.

[0042] The bottom of the support leg 204 is provided with a rotating brush 210, which is located in the grooves on both sides of the substrate tank. The rotating brush 210 has water outlet holes distributed on it.

[0043] The high-pressure nozzle 209 and the water outlet are respectively connected to the water distribution pipe;

[0044] The clamping arms 208 are a pair, located on both sides of the housing 201. Each clamping arm 208 has a follower roller 211, and the clamping arms 208 are clamped to both sides of the substrate groove by the follower roller 211.

[0045] A reversing valve 206 is provided on the water distribution pipe inside the housing 201. Water entering from the high-pressure quick connector 202 is controlled by the reversing valve 206 to enter the high-pressure nozzle 209 and water outlet at the front end of the housing 201, or the high-pressure nozzle 209 and water outlet at the rear end.

[0046] The reversing valve 206 has a reversing handle located outside the housing 201. When the cleaner moves to the end of the substrate tank, the reversing handle hits the limiting plate, thereby switching the reversing valve 206.

[0047] The high-pressure nozzle 209 on the manifold 205 sprays at an angle away from the housing 201 and toward the substrate tank. The reaction force of the spray pushes the cleaner to move on the substrate tank.

[0048] The rotating brush 210 rotates horizontally. The water outlets on the rotating brush 210 are arranged around the circumference of the rotating brush 210, and the spray direction of the water outlets is oblique. Through the reaction force of the spray, the rotating brush 210 is in a rotating state.

[0049] The housing 201 has a rotating seat on its side. The end of the clamping arm 208 is hinged to the rotating seat. A spring 212 is provided between the spring buckle of the clamping arm 208 near the middle position and the spring buckle of the rotating seat. When the clamping arm 208 is clamping the substrate groove, the spring buckle of the clamping arm 208 is lower than the spring buckle of the rotating seat. When the clamping arm 208 is flipped up to release the clamping, the spring buckle of the clamping arm 208 is higher than the spring buckle of the rotating seat.

[0050] The rotating seat is provided with a limit pin 207 for fixing the clamping arm 208 to maintain clamping and releasing clamping.

[0051] The cleaner is the working terminal of the whole set of equipment. A high-pressure quick connector 202 is set at the rear of the housing 201, which is connected to a high-pressure water pipe and connected to the water supply truck.

[0052] Clamping arms 208 are provided on both sides of the housing 201. When preparing for work, push the cleaner into the substrate tank from one end. After the roller 203 at the bottom of the housing 201 contacts the upper surface of the substrate tank and confirms that the back-and-forth movement is smooth, pull the limit pin 207 to flip the clamping arm 208 down. This ensures that the follower roller 211 on the clamping arm 208 is always in close contact with the inclined surface a (side) of the substrate tank under the tension of the spring 212. After the clamping is effective, release the limit pin 207 to ensure that the clamping arm 208 will not flip up during work.

[0053] As shown in the figure, support legs 204 are provided at the front and rear of the housing 201. A manifold 205 is installed on the support legs 204. There are branch water pipes inside the manifold 205. One end of the branch water pipe is connected to the distribution water pipe, and the other end is connected to the threaded interface on the surface of the manifold 205. Fourteen high-pressure nozzles 209 are symmetrically distributed at the front and rear. The high-pressure water pump of the water supply truck provides high-pressure water flow to the high-pressure nozzles 209 through the water pipe. The high-pressure water flow washes and cleans the surface of the substrate tank and the grooves. The reaction force generated by the high-pressure water flow drives the cleaner to move forward and backward.

[0054] When moving forward, the seven high-pressure nozzles 209 at the rear spray, while the seven high-pressure nozzles 209 at the front close.

[0055] Four rotating brushes 210 are provided at the end of the support leg 204. Each brush 210 has several eccentric water outlets. The brushes rotate by spraying water, which drives the brushes to clean and rinse the grooves b of the substrate tank.

[0056] When the cleaner reaches the end of the substrate tank, the handle of the reversing valve 206 contacts the end limit plate. The reversing valve 206 changes the direction of water flow inside the cleaner, causing the seven high-pressure nozzles 209 at the front to open and the seven high-pressure nozzles 209 at the rear to close. The cleaner then moves in the opposite direction to perform a second cleaning and returns to the starting point of the substrate tank.

[0057] After returning to the starting point, the water supply truck stops supplying water, pulls the limit pin 207, lifts the clamping arm 208, pulls out the cleaner, pushes it into the next substrate tank, and repeats the above process.

[0058] This invention mainly fills the gap in modern agricultural glass greenhouse substrate tank cleaning equipment, replacing manual cleaning with a dedicated cleaning machine, which is more efficient and saves costs.

[0059] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
