Abstract
Description
Technical Field
[0001] This application relates to the field of screening equipment technology, and in particular to a sand culture substrate treatment device. Background Technology
[0002] Sand culture is a soilless cultivation technique that uses river sand as a growing substrate and supplies nutrient solution to crops via drip irrigation. Sand particles with a diameter of 0.5–3.0 mm are preferred for sand culture. It is widely used in many places, especially in areas with severe water shortages, such as the Gobi Desert and semi-desert regions, as a water-saving agricultural practice.
[0003] Because the different particle sizes and physical properties of river sand vary greatly, which determines the cultivation effect, it is necessary to screen the river sand by particle size and then perform spectral detection on sand particles within a certain particle size range to detect some characteristics of the sand particles. However, existing screening equipment uses vibrators to vibrate the screen to screen the material. However, vibrators are expensive, resulting in high operating costs for the screening equipment, which is difficult to adapt to experimental scenarios. Furthermore, if the vibrator fails, the entire screening equipment will become unusable. Utility Model Content
[0004] The main purpose of this application is to provide a sand culture substrate treatment device, which aims to solve the technical problem that existing sand screening equipment uses vibrators to generate vibrations, resulting in high operating costs.
[0005] To achieve the above objectives, this application provides a sand culture substrate processing device, including a workbench, a screening cart movably mounted on the top of the workbench, a discharge trough for passing sand particles screened out by the screening cart through the discharge trough, a collection mechanism for collecting sand particles below the discharge trough, a reciprocating drive mechanism on the top of the workbench for driving the screening cart to move back and forth on the workbench, and multiple protrusions on the top of both sides of the discharge trough of the workbench for contacting the bottom of the screening cart.
[0006] Optionally, the screening cart includes a material frame, with a screen at the bottom and rollers located outside the screen. The rollers roll along both sides of the material discharge chute and contact the protrusions.
[0007] Optionally, the height of the multiple protrusions increases sequentially in the direction away from the reciprocating drive mechanism.
[0008] Optionally, at least one first spring is connected between the top of the workbench and the bottom of the screen.
[0009] Optionally, guide grooves are provided on the top of both sides of the worktable at the bottom of the material discharge trough, and the rollers roll in the guide grooves.
[0010] Optionally, the reciprocating drive mechanism includes a first motor mounted on the workbench, the output shaft of the first motor being detachably connected to a first connecting rod, the other end of the first connecting rod being hinged to a second connecting rod, and the other end of the second connecting rod being hinged to the side wall of the screening cart.
[0011] Optionally, the receiving mechanism includes an inclined guide plate, and a collection box is provided below the downwardly inclined end of the guide plate, with the collection box located on one side of the workbench.

[0015] The beneficial effects that this application can achieve are as follows:
[0016] This application includes a workbench, a screening cart is movably mounted on the top of the workbench, a discharge trough is provided on the workbench for passing sand particles screened out by the screening cart, a receiving mechanism for collecting sand particles is provided below the discharge trough, a reciprocating drive mechanism is provided on the top of the workbench for driving the screening cart to move back and forth on the workbench, and multiple protrusions are provided on the top of both sides of the discharge trough of the workbench for contacting the bottom of the screening cart. When screening sand, this application uses a reciprocating drive mechanism to move a screening cart loaded with sand back and forth on the worktable. When the screening cart moves and passes over the protrusion, it bounces up to a certain height, thus simulating the vibration effect on the screening cart. The sand in the screening cart is then screened under the vibration effect. The screened sand can then pass through the discharge chute and enter the receiving mechanism, thereby completing the screening work. Therefore, this application simplifies the traditional screening method using a vibrator by using a reciprocating screening cart and the protrusion to create a bumping vibration effect, saving equipment costs and making it suitable for low-cost, temporary use in experimental scenarios.

[0027] Example
[0028] Reference Figures 1-2 This embodiment provides a sand culture substrate processing device, including a workbench 110. A screening cart 120 is movably mounted on the top of the workbench 110. A material leakage trough 111 is provided on the workbench 110 for passing sand particles screened out by the screening cart 120. A material collection mechanism 130 for collecting sand particles is provided below the material leakage trough 111. A reciprocating drive mechanism 140 is provided on the top of the workbench 110 for driving the screening cart 120 to move back and forth on the workbench 110. Multiple protrusions 150 are provided on the top of both sides of the workbench 110 located in the material leakage trough 111. The protrusions 150 are for contacting the bottom of the screening cart 120.
[0029] In this embodiment, when screening sand, the reciprocating drive mechanism 140 drives the screening cart 120 containing sand to move back and forth on the workbench 110. When the screening cart 120 moves and passes the protrusion 150, it will bounce up to a certain height, thus simulating the vibration of the screening cart 120. The sand in the screening cart 120 is then screened under the vibration. The screened sand can then pass through the discharge chute 111 and enter the receiving mechanism 130, thus completing the screening work. Therefore, this embodiment can create a bumping vibration effect based on the reciprocating screening cart 120 and the protrusion 150, which simplifies the traditional method of screening with a vibrator, saves equipment costs, and is suitable for low-cost and temporary use in experimental scenarios.
[0030] It should be noted that because there are multiple protrusions 150 here, multiple bumping and vibration effects can be performed, so that the screening operation can be completed in one reciprocating movement, thus improving the screening efficiency.
[0031] As an optional implementation, the screening cart 120 includes a material frame 121, a screen 122 is provided at the bottom of the material frame 121 and a roller 123 located outside the screen 122. The roller 123 rolls along both sides of the material discharge trough 111 and contacts the protrusion 150.
[0032] In this embodiment, the material frame 121 and the screen 122 form a space that can accommodate a certain amount of sand particles. When the screening cart 120 moves via the rollers 123, the entire screening cart 120 will vibrate and shake when the rollers 123 pass over the protrusion 150. It should be noted that the protrusion 150 should have an upwardly arched arc structure to allow the rollers 123 to transition smoothly, reducing wear on the rollers 123 and improving their service life.
[0033] As an alternative implementation, the protrusion height of the plurality of protrusions 150 increases sequentially in the direction away from the reciprocating drive mechanism 140.
[0034] In this embodiment, taking the example of two protrusions 150 on both sides of the material trough 111, when the screening cart 120 passes the first protrusion 150 with a lower height, the first vibration screening can be performed. Since there is a lot of sand in the screening cart 120 at this time, if the bumps are too large, the sand will easily spill out. Therefore, the first screening can be performed by forming a small vibration through the protrusion 150 with a lower height. After the first screening, there is less sand in the screening cart 120, and the sand is not easy to spill out. The second protrusion 150 with a higher height can form a larger vibration for screening, which further promotes the screening effect. By reasonably arranging the height of the protrusions 150, the sand spillage during the screening process can be effectively prevented, while ensuring the screening effect.
[0035] As an optional implementation, at least one first spring 160 is connected between the top of the workbench 110 and the bottom of the screen 122. The first spring 160 can keep the screening cart 120 within a certain vibration range, preventing the screening cart 120 from overturning due to excessive bumps, and playing a certain limiting role.
[0036] As an optional implementation, the top of both sides of the workbench 110 is provided with guide grooves 112, and the rollers 123 roll within the guide grooves 112. The guide grooves 112 have a certain guiding effect on the rollers 123, so that the entire screening cart 120 can travel stably in a straight line and prevent deviation.
[0037] As an optional implementation, the reciprocating drive mechanism 140 includes a first motor 141 disposed on the worktable 110. The output shaft of the first motor 141 is detachably connected to a first connecting rod 142. The other end of the first connecting rod 142 is hinged to a second connecting rod 143. The other end of the second connecting rod 143 is hinged to the side wall of the screening cart 120.
[0038] In this embodiment, when reciprocating drive is required, the first motor 141 can drive the first connecting rod 142 to rotate, thereby causing the second connecting rod 143 to swing, which in turn drives the screening cart 120 to move reciprocally, achieving automatic drive. It should be noted that since the output shaft of the first motor 141 is detachably connected to the first connecting rod 142, if the first motor 141 malfunctions, the first connecting rod 142 can be removed from the output shaft of the first motor 141 for manual drive, allowing for screening operations. This provides flexibility. The output shaft of the first motor 141 can be detachably connected to the first connecting rod 142 via an intermediate connecting component such as a coupling.
[0039] In other embodiments, the reciprocating drive mechanism 140 can also be driven automatically by a telescopic cylinder, or it can be operated manually by a lever.
[0040] As an optional implementation, the receiving mechanism 130 includes an inclined guide plate 131, with a collection box 132 located below the downwardly inclined end of the guide plate 131 on one side of the workbench 110. Screened sand particles fall onto the inclined guide plate 131 and can then slide into the collection box 132 on one side of the workbench 110, facilitating subsequent removal of the collection box 132.
[0041] It should be noted that the cross-section of the guide plate 131 is arc-shaped or has a trough-shaped structure with side plates to prevent sand particles from spilling out from both sides of the guide plate 131.
[0042] As an optional implementation, the receiving mechanism 130 also includes a base plate 133 disposed below the guide plate 131. A plurality of guide cylinders 134 are disposed on the base plate 133. A second spring 135 is movably disposed inside the guide cylinder 134. The second spring 135 extends out of the top of the guide cylinder 134 and is connected to the bottom of the guide plate 131. A vibration mechanism 170 is also disposed on the base plate 133. The vibration mechanism 170 is used to generate vibration on the guide plate 131 at a certain frequency.
[0043] In this embodiment, the vibration mechanism 170 can vibrate the guide plate 131, thereby promoting the sand particles on the guide plate 131 to slide into the collection box 132. At the same time, the second spring 135 supports and promotes the swing of the guide plate 131, and the guide cylinder 134 can guide the second spring 135 up and down.
[0044] In one optional implementation, the vibration mechanism 170 includes a second motor 171 mounted on the base plate 133. The output shaft of the second motor 171 is connected to a cam 172, which is used to contact the bottom of the guide plate 131. The second motor 171 can drive the cam 172 to rotate, and the highest point of the cam 172 can impact the bottom of the guide plate 131 to generate vibration, thereby realizing the function of automatically vibrating the guide plate 131.
[0045] It should be noted that both the first motor 141 and the second motor 171 mentioned above can be stepper motors or servo motors, and both can precisely control the speed to achieve low-speed operation and meet the usage requirements.
[0046] As an optional implementation, a protective pad 180 is provided at the bottom of the guide plate 131. The protective pad 180 is used to contact the cam 172. The protective pad 180 can reduce the impact wear of the cam 172 on the bottom of the guide plate 131 and improve its service life.
[0047] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
