Description

TECHNICAL FIELD

[0001] The utility model relates to tobacco seedling raising technical field, especially in kind with cleaning device's seedling raising pond. BACKGROUND

[0002] Floating seedling raising technology is an advanced tobacco seedling raising mode, which provides growth environment for tobacco seedlings by using seedling raising liquid in the seedling raising pond and seedling raising tray floating on the seedling raising liquid. In the seedling raising process, as the growth of tobacco seedlings, the excrement gradually increases, which leads to the continuous increase of the content of organic matter in the seedling raising liquid. In addition, the death of plankton, the rot of aquatic plants and the excessive amount of seedling raising fertilizer also lead to the increase of the content of organic matter in the seedling raising liquid.

[0003] Microorganisms release gas in the process of decomposing organic matter. When the content of organic matter in the seedling raising pond is too high, the gas will be emitted to the surface of the seedling raising liquid in the form of scum, and the excessive organic matter will also float on the surface of the seedling raising liquid to form an oil film. These will lead to the increase of the viscosity of the seedling raising liquid and the turbidity of the water quality, thereby affecting the growth of tobacco seedlings. Furthermore, the excessive organic matter and scum will adhere to the inner surface of the pond body, and the inner wall of the pond body needs to be cleaned regularly. When the volume of the seedling raising pond is large, manual cleaning is relatively complex and tedious, which increases the difficulty of cleaning the pond body. SUMMARY

[0004] The utility model discloses a kind of seedling raising ponds with cleaning device, which can automatically clean the scum on the surface of seedling raising liquid in the pond body and the inner wall of the pond body, thereby reducing the cleaning difficulty.

[0005] To solve the above technical problems, an embodiment of the utility model discloses a seedling raising pond with cleaning device, comprising:

[0006] The pond body has a receiving cavity inside, and the receiving cavity has a first side wall and a second side wall arranged oppositely. The receiving cavity is used to hold the seedling raising liquid.

[0007] The fixing seat is provided with a mounting slot penetrating through the fixing seat in the first direction.

[0008] The first elastic member is arranged in the mounting slot and can produce compression deformation in the first direction.

[0009] The scraper is arranged on one side of the first elastic member in the first direction. The upper surface of the scraper is provided with a collection groove extending in the first direction. One end of the scraper is inserted into the mounting slot and abuts against the first elastic member. The other end of the scraper abuts against the first side wall.

[0010] The cleaning block is arranged on the side of the first elastic member away from the scraper in the first direction, one end of the cleaning block is inserted into the mounting groove and abuts against the first elastic member, and the other end of the cleaning block abuts against the second side wall;

[0011] The driving mechanism is directly or indirectly connected with the fixed seat and is used for driving the fixed seat, the scraper and the cleaning block connected with the fixed seat to reciprocate in the second direction perpendicular to the first direction.

[0012] The scraper and the cleaning block are tightly attached to the first side wall and the second side wall under the elastic force of the first elastic member. When it is necessary to clean the floating matter on the surface of the seedling liquid, the driving mechanism is started, and the fixed seat, the scraper and the cleaning block are driven to reciprocate in the second direction. During the reciprocation, the ends of the scraper and the cleaning block away from the first elastic member scrape the floating matter on the first side wall and the second side wall, so that the first side wall and the second side wall are free of the floating matter. The floating matter scraped from the first side wall and the second side wall is concentrated on the surface of the seedling liquid. While the fixed seat, the scraper and the cleaning block reciprocate in the second direction, the scraper can also scrape the floating matter concentrated on the surface of the seedling liquid. Since the floating matter floats on the upper surface of the seedling liquid and the lower surface of the scraper is flush with or slightly lower than the upper surface of the seedling liquid, when the scraper moves in the second direction, the floating matter can flow along the upper surface of the scraper into the collecting groove, so that the floating matter is collected in the collecting groove, and the cleaning and collection of the floating matter on the surface and the inner wall of the pool body are completed.

[0013] By adopting the technical scheme, the floating matter on the surface of the seedling liquid in the pool body and the inner wall of the pool body can be automatically cleaned, so that the cleaning difficulty is reduced and the manpower is saved.

[0014] Optionally, the second side wall is provided with a sliding groove extending in the second direction, and the driving mechanism comprises:

[0015] A sliding block is at least partially arranged in the sliding groove and can reciprocate in the sliding groove, the sliding block is provided with a threaded hole penetrating the sliding block in the second direction, and the sliding block is directly or indirectly connected with the fixed seat;

[0016] A lead screw extends in the second direction, and two ends of the lead screw are respectively rotatably connected with the pool body, the lead screw penetrates the threaded hole and is threadedly connected with the threaded hole;

[0017] A motor is connected with the lead screw and is used for driving the lead screw to rotate around the axis line thereof.

[0018] By adopting the technical scheme, the sliding block can be limited to slide in the sliding groove, so that the sliding block can only slide horizontally along the fixed track when reciprocated by the lead screw, and the stability of the sliding block during the sliding process is improved.

[0019] Optionally, the sliding block is provided with a sliding channel penetrating the sliding block along a third direction, the third direction being perpendicular to the first direction and the second direction respectively, and the seedling tank further comprises a sliding rod, the sliding rod being arranged in the sliding channel and being capable of sliding in the sliding channel along the third direction, and a bottom end of the sliding rod being connected with the fixed seat.

[0020] By arranging the sliding rod and the sliding channel and connecting the bottom end of the sliding rod with the fixed seat, the scraper and the cleaning block can be driven by the sliding rod to move along the third direction, and when the liquid level of the seedling liquid changes, the operator can adjust the height of the scraper and the cleaning block by moving the sliding rod along the vertical direction, so that the lower surface of the scraper is flush with or slightly lower than the liquid surface of the seedling liquid in the accommodating cavity, thereby facilitating the cleaning and collection of the floating scum under different liquid levels.

[0021] Optionally, the sliding block is T-shaped, and the sliding block comprises:

[0022] a connecting portion arranged outside the sliding groove, and the sliding channel being arranged on the connecting portion;

[0023] a limiting portion arranged at the middle portion of the connecting portion, the limiting portion being inserted into the sliding groove, and the threaded hole being arranged on the limiting portion.

[0024] When the motor drives the screw rod to rotate around its axis, the limiting portion can only slide in the sliding groove along the horizontal direction, so that the movement track of the connecting portion, the sliding rod arranged in the sliding channel, the fixed seat, the scraper and the cleaning block fixedly connected with the sliding rod along the horizontal direction is also relatively fixed, thereby indirectly increasing the stability of the scraper and the cleaning block during the cleaning process.

[0025] Optionally, the seedling tank further comprises:

[0026] a limiting member arranged at the upper end of the sliding rod, the limiting member being hingedly connected with the sliding rod, and the limiting member being capable of rotating relative to the sliding rod between a first position and a second position; when the limiting member is rotated to the first position, a projection of the limiting member along the third direction is at least partially located outside the contour range of the sliding channel; and when the limiting member is rotated to the second position, the projection of the limiting member along the third direction is located within the contour range of the sliding channel.

[0027] a locking assembly connected with the limiting member, the locking assembly being used for locking the limiting member when the limiting member is rotated to the first position and the second position, so as to limit the rotation of the limiting member relative to the sliding rod.

[0028] According to the technical scheme, when the limiting piece rotates to the first position, the limiting piece is in the limiting state and partially protrudes from the side wall of the sliding channel. At this time, the locking assembly is used to lock the limiting piece, and the limiting piece can be continuously kept at the first position, so that the slide rod is prevented from sliding out from below the sliding channel and falling. When the limiting piece rotates to the second position, the limiting piece is in the non-limiting state and does not protrude from the side wall of the sliding channel. At this time, the locking assembly is used to lock the limiting piece, and the limiting piece can be continuously kept at the second position, so that the slide rod can slide out from below the sliding channel, and the slide rod and the sliding block are separated from each other, thereby facilitating the operator to disassemble and assemble the device.

[0029] Optionally, a groove is arranged on the side wall of the slide rod, and one end of the limiting piece is arranged in the groove. The groove has a first inner surface and a second inner surface arranged opposite to each other, and a through hole is arranged on the second inner surface. The locking assembly comprises:

[0030] a rotating shaft inserted into the through hole. The rotating shaft can rotate in the through hole and slide between a third position and a fourth position along the extension direction of the through hole. The two ends of the rotating shaft are a locking end and a free end, respectively. The locking end is located in the groove, and the free end passes through the through hole and can extend out of the through hole. The limiting piece is connected to the rotating shaft;

[0031] a first magnet arranged on the first inner surface;

[0032] a second magnet arranged on the locking end of the rotating shaft;

[0033] a relief groove arranged on the outer wall of the slide rod and communicating with the through hole. When the rotating shaft is located at the third position, the first magnet is separated from the second magnet, and the free end is located outside the relief groove. When the rotating shaft is located at the fourth position, the first magnet is attracted to the second magnet, and the free end is located in the relief groove.

[0034] According to the above technical scheme, the first magnet and the second magnet are used to lock the position of the limiting piece. By arranging the rotating shaft, the operator can conveniently rotate the limiting piece, and the operator can also conveniently control the attraction and separation of the first magnet and the second magnet. The structure is simple, and the operation is convenient.

[0035] Optionally, a second elastic member is arranged between the second inner surface and the limiting piece. The second elastic member is sleeved on the rotating shaft, and the second elastic member is used to provide an acting force of the limiting piece towards the first inner surface.

[0036] According to the above technical scheme, by arranging the second elastic member, an acting force of the limiting piece towards the first magnet can be applied, so that when the rotating shaft is located at the fourth position, the second magnet can abut against the first magnet, the first magnet and the second magnet are attracted more closely, and the locking effect of the locking assembly is enhanced.

[0037] Optionally, the shape of the giving-way slot is cross-shaped, and the giving-way slot comprises two first clamping slots and two second clamping slots which are mirror images relative to the axis of the rotating shaft; the free end is provided with a clamping plate which extends along the radial direction of the rotating shaft; when the limiting piece is located at the first position and the rotating shaft is located at the fourth position, the clamping plate can be inserted into one of the first clamping slots, and the shape of the clamping plate is matched with the shape of the first clamping slot; when the limiting piece is located at the second position and the rotating shaft is located at the fourth position, the clamping plate can be inserted into one of the second clamping slots, and the shape of the clamping plate is matched with the shape of the second clamping slot.

[0038] By adopting the above technical scheme, the cross-shaped giving-way slot can not only limit the clamping plate to prevent the clamping plate and the rotating shaft from rotating, but also facilitate the operator to insert the thumb and the index finger into two first clamping slots or two second clamping slots when pulling the free end of the rotating shaft, so as to increase the contact area between the fingers and the rotating shaft, thereby facilitating the operator to contact the rotating shaft and reducing the operation difficulty.

[0039] Optionally, the circumferential surface of the side of the rotating shaft close to the free end is provided with a pattern or an anti-skid sleeve.

[0040] By adopting the above technical scheme, the pattern or the anti-skid sleeve can increase the roughness of the outer circumferential surface of the rotating shaft, thereby increasing the friction between the outer circumferential surface of the rotating shaft and the fingers of the operator, avoiding the slipping of the operator during the gripping process, and making the operator more easily adjust the position of the rotating shaft.

[0041] Optionally, the lower surface of the scraper and the cleaning block is provided with a floating plate which is a PVC buoyancy plate or an EVA buoyancy plate.

[0042] By adopting the above technical scheme, the scraper and the cleaning block can float on the surface of the breeding liquid in the pool body under the action of the buoyancy, and the scraper and the cleaning block can be self-adaptively adjusted according to the liquid level in the pool body, so that the operator does not need to manually adjust the position of the scraper and the cleaning block according to the liquid level in the pool body, thereby reducing the workload of the operator and improving the work efficiency.

[0058] In order to make the purpose, technical scheme and advantages of the utility model more clear, the embodiments of the utility model will be further described in detail below with reference to the drawings.

[0059] Referring to Figure 1 and Figure 4 The embodiments of the utility model disclose a seedling pool with a cleaning device, which comprises:

[0060] The pool body 1 is internally provided with a containing cavity 11, the containing cavity 11 has oppositely arranged first and second side walls 111 and 112, and the containing cavity 11 is used for containing seedling liquid;

[0061] The fixed seat 21 is arranged in the pool body 1, and the fixed seat 21 is provided with a mounting groove 211 penetrating the fixed seat 21 along a first direction (such as the X direction shown in the figure); Figure 1

[0062] The first elastic member 22 is arranged in the mounting groove 211, and the first elastic member 22 can produce compression deformation along the first direction;

[0063] ​The scraper 23 is arranged on one side of the first elastic member 22 along the first direction. An upper surface of the scraper 23 is provided with a collecting groove 231 extending along the first direction. One end of the scraper 23 is inserted into the mounting groove 211 and abuts against the first elastic member 22. The other end of the scraper 23 abuts against the first side wall 111.

[0064] The cleaning block 24 is arranged on the side of the first elastic member 22 away from the scraper 23 along the first direction. One end of the cleaning block 24 is inserted into the mounting groove 211 and abuts against the first elastic member 22. The other end of the cleaning block 24 abuts against the second side wall 112.

[0065] The driving mechanism 3 is directly or indirectly connected to the fixed seat 21. The driving mechanism 3 is used to drive the fixed seat 21 and the scraper 23 and the cleaning block 24 connected to the fixed seat 21 to reciprocate along a second direction (e.g. the Y direction shown in FIG. 1) perpendicular to the first direction. Figure 1

[0066] In the embodiment, the upper surface of the scraper 23 is higher than the liquid surface of the seedling liquid in the accommodating cavity 11. The lower surface of the scraper 23 can be flush with the liquid surface of the seedling liquid or slightly lower than the liquid surface of the seedling liquid. The scraper 23 and the cleaning block 24 are tightly attached to the first side wall 111 and the second side wall 112 respectively under the elastic force of the first elastic member 22. When it is necessary to clean the floating scum on the surface of the seedling liquid, the driving mechanism 3 is started to drive the fixed seat 21, the scraper 23 and the cleaning block 24 to reciprocate along the Y direction. During the movement, the ends of the scraper 23 and the cleaning block 24 away from the first elastic member 22 scrape the floating scum on the first side wall 111 and the second side wall 112, so that the first side wall 111 and the second side wall 112 are free of the floating scum. The floating scum scraped from the first side wall 111 and the second side wall 112 is concentrated on the surface of the seedling liquid.

[0067] When the fixed seat 21, the scraper 23 and the cleaning block 24 move along the Y direction, the scraper 23 can also scrape the floating scum concentrated on the surface of the seedling liquid. Specifically, the upper surface of the scraper 23 has two circular-arc-shaped guide surfaces 232 arranged opposite along the Y direction. Since the floating scum floats on the upper surface of the seedling liquid, the height of the floating scum is greater than the height of the upper surface of the seedling liquid. When the scraper 23 moves along the Y direction, the floating scum can flow along the guide surfaces 232 into the collecting groove 231, so as to collect the floating scum in the collecting groove 231, thereby completing the cleaning and collection of the floating scum on the surface and the inner wall of the pool body 1.

[0068] By using the above technical solution, the floating scum on the surface of the seedling liquid in the pool body 1 and the inner wall of the pool body 1 can be automatically cleaned, thereby reducing the cleaning difficulty and saving manpower.

[0069] Optionally, the first elastic member 22 is a spring. Optionally, the spring is a compression spring.​

[0070] Further, referring to Figure 1 and Figure 3 , the second side wall 112 is provided with a sliding groove 31 extending along the second direction, and the driving mechanism 3 comprises:

[0071] a sliding block 32, at least partially arranged in the sliding groove 31, the sliding block 32 being capable of reciprocating sliding along the sliding groove 31, the sliding block 32 being provided with a threaded hole 321 extending through the sliding block 32 along the second direction, the sliding block 32 being directly or indirectly connected with the fixed seat 21;

[0072] a lead screw 33 extending along the second direction, both ends of the lead screw 33 being rotatably connected with the pool body 1, the lead screw 33 penetrating through the threaded hole 321 and being threadedly connected with the threaded hole 321;

[0073] a motor 34 connected with the lead screw 33, for driving the lead screw 33 to rotate around its axis.

[0074] In an embodiment of the present application, the motor 34 is arranged on the outer wall of the pool body 1.

[0075] In an embodiment of the present application, the lead screw 33 is connected with the output end of the motor 34 through a shaft coupling.

[0076] When the motor 34 is started, the motor 34 can drive the lead screw 33 to rotate, and the lead screw 33 drives the sliding block 32 to move in the sliding groove 31, thereby driving the fixed seat 21, the scraper 23 and the cleaning block 24 to move along the Y direction.

[0077] By adopting the above technical scheme, the sliding block 32 can be limited to slide in the sliding groove 31, so that the sliding block 32 can only slide along the fixed track in the horizontal direction when being driven by the lead screw 33 to reciprocate, and will not be skewed, thereby increasing the stability of the sliding block 32 during sliding.

[0078] Specifically, referring to Figure 1 and Figure 3 , the sliding block 32 is T-shaped, and the sliding block 32 comprises:

[0079] a connecting portion 323 arranged outside the sliding groove 31, and a sliding channel 322 arranged on the connecting portion 323;

[0080] a limiting portion 324 arranged at the middle portion of the connecting portion 323, the limiting portion 324 being inserted into the sliding groove 31, and the threaded hole 321 being arranged on the limiting portion 324.

[0081] With the above technical scheme, when the motor 34 drives the screw rod 33 to rotate around its axis, the limiting part 324 can slide in the horizontal direction within the sliding groove 31 relative to the sliding groove 31, so that the movement track of the connecting part 323 fixedly connected with the limiting part 324, the sliding rod 35 arranged in the sliding channel 322, and the fixed seat 21, the scraper 23 and the cleaning block 24 fixedly connected with the sliding rod 35 moving in the horizontal direction is also relatively fixed, thereby indirectly increasing the stability of the scraper 23 and the cleaning block 24 in the cleaning process.

[0082] Further, referring to Figure 2 and Figure 3 , the sliding block 32 is provided with a sliding channel 322 penetrating the sliding block 32 in a third direction (for example, the Z direction shown in Figure 3 ). The third direction is perpendicular to the first direction and the second direction. In the embodiment, the third direction is the vertical direction. The rearing pond further includes a sliding rod 35 arranged in the sliding channel 322 and capable of sliding in the sliding channel 322 in the third direction. The bottom end of the sliding rod 35 is connected with the fixed seat 21.

[0083] With the above technical scheme, by arranging the sliding rod 35 and the sliding channel 322, and connecting the bottom end of the sliding rod 35 with the fixed seat 21, the scraper 23 and the cleaning block 24 can move in the Z direction under the driving action of the sliding rod 35. When the liquid level of the rearing liquid changes, the operator can adjust the height of the scraper 23 and the cleaning block 24 by moving the sliding rod 35 in the vertical direction, so that the lower surface of the scraper 23 is flush with or slightly lower than the liquid surface of the rearing liquid in the accommodating cavity 11, thereby facilitating the cleaning and collection of the floating scum under different liquid levels.

[0084] Specifically, referring to Figure 4 , the lower surface of the scraper 23 and the cleaning block 24 is provided with a floating plate 25 made of a material with small density. For example, the floating plate 25 is a PVC buoyancy plate or an EVA buoyancy plate.

[0085] With the above technical scheme, by arranging the floating plate 25, the scraper 23 can float on the surface of the rearing liquid in the pond body 1 under the action of the buoyancy. When the height of the rearing liquid in the pond body 1 changes, since the sliding rod 35 can slide in the vertical direction within the sliding channel 322, the height of the fixed seat 21, the scraper 23 and the cleaning block 24 will also automatically change with the liquid level of the rearing liquid, so that the scraper 23 and the cleaning block 24 can be spontaneously adjusted according to the height of the rearing liquid in the pond body 1, without the need for the staff to manually adjust the position of the scraper 23 and the cleaning block 24 according to the water level in the pond body 1, thereby reducing the workload of the staff and improving the work efficiency.

[0086] Further, referring to Figure 2 , Figure 3 andFigure 6 The rearing pond further comprises:

[0087] The limiting piece 4 is arranged at the upper end of the sliding rod 35, and the limiting piece 4 is hingedly connected to the sliding rod 35. The limiting piece 4 can rotate relative to the sliding rod 35 between a first position and a second position. When the limiting piece 4 rotates to the first position, a projection of the limiting piece 4 along a third direction is at least partially located outside the contour range of the sliding channel 322. At this time, the limiting piece 4 can block the upper end of the sliding rod 35 from being pulled out of the sliding channel 322. When the limiting piece 4 rotates to the second position, the projection of the limiting piece 4 along the third direction is located within the contour range of the sliding channel 322. At this time, the limiting piece 4 will not block the upper end of the sliding rod 35 from being pulled out of the sliding channel 322.

[0088] The locking assembly 5 is connected to the limiting piece 4. The locking assembly 5 is used to lock the limiting piece 4 when the limiting piece 4 rotates to the first position and the second position, so as to limit the rotation of the limiting piece 4 relative to the sliding rod 35.

[0089] When the limiting piece 4 rotates to the first position, the limiting piece 4 partially protrudes from the side wall of the sliding channel 322 in a limiting state. At this time, the limiting piece 4 is locked by the locking assembly 5, and the limiting piece 4 can be continuously maintained in the first position, so that the sliding rod 35 can be prevented from being pulled out from below the sliding channel 322 and falling. When the limiting piece 4 rotates to the second position, the limiting piece 4 does not protrude from the side wall of the sliding channel 322 in a non-limiting state. At this time, the limiting piece 4 is locked by the locking assembly 5, and the limiting piece 4 can be continuously maintained in the second position. The sliding rod 35 can be pulled out from below the sliding channel 322, so that the sliding rod 35 and the sliding block 32 are separated from each other, thereby facilitating the operator to disassemble and assemble the device.

[0090] Specifically, referring to Figure 5 and Figure 8 , the side wall of the sliding rod 35 is provided with a groove 51, one end of the limiting piece 4 is arranged in the groove 51, the groove 51 has a first inner surface 511 and a second inner surface 512 arranged oppositely, and the second inner surface 512 is provided with a through hole 513; the locking assembly 5 comprises:

[0091] A rotating shaft 52 is inserted into the through hole 513. The rotating shaft 52 can rotate in the through hole 513 and slide between a third position and a fourth position along the extension direction of the through hole 513. The two ends of the rotating shaft 52 are respectively a locking end 521 and a free end 522. The locking end 521 is located in the groove 51, and the free end 522 passes through the through hole 513 and can extend outside the through hole 513. The limiting piece 4 is connected to the rotating shaft 52.

[0092] A first magnet 53 is arranged on the first inner surface 511.

[0093] The second magnet 54 is arranged on the locking end 521 of the rotating shaft 52.

[0094] The outer wall of the slide rod 35 is provided with a clearance slot 55, which is connected with the through hole 513. When the rotating shaft 52 is located at the third position, the first magnet 53 is separated from the second magnet 54, and the free end 522 is located outside the clearance slot 55. When the rotating shaft 52 is located at the fourth position, the first magnet 53 is attracted to the second magnet 54, and the free end 522 is located in the clearance slot 55, so as to prevent the free end 522 from interfering with the sliding block 32 when the slide rod 35 is pulled out of the sliding channel 322.

[0095] When the operator needs to rotate the limiting piece 4, first, the finger is inserted into the clearance slot 55, and the free end 522 of the rotating shaft 52 is pulled away from the slide rod 35, so as to move the rotating shaft 52 to the third position, so that the first magnet 53 is separated from the second magnet 54, thereby releasing the locking of the limiting piece 4. Then, the rotating shaft 52 is rotated, so that the limiting piece 4 is rotated to the preset position. After the limiting piece 4 is rotated to the preset position, the operator pushes the rotating shaft 52 towards the slide rod 35, so as to move the rotating shaft 52 to the fourth position, so that the first magnet 53 is attracted to the second magnet 54, thereby completing the locking of the limiting piece 4.

[0096] By using the above technical scheme, the position of the limiting piece 4 can be locked by the first magnet 53 and the second magnet 54. By arranging the rotating shaft 52, the operator can conveniently rotate the limiting piece 4, and can also conveniently control the attraction and separation of the first magnet 53 and the second magnet 54. The structure is simple, and the operation is convenient.

[0097] Specifically, referring to Figure 6 , the second inner surface 512 and the limiting piece 4 are provided with a second elastic element 56, the second elastic element 56 is sleeved on the rotating shaft 52, and the second elastic element 56 is used for providing an acting force of the limiting piece 4 towards the first inner surface 511.

[0098] Optionally, the second elastic element 56 is a compression spring.

[0099] By using the above technical scheme, by arranging the second elastic element 56, an acting force of the limiting piece 4 towards the first magnet 53 can be applied, so that when the rotating shaft 52 is located at the fourth position, the second magnet 54 can be closely arranged on the first magnet 53, the first magnet 53 and the second magnet 54 are more closely attracted, thereby enhancing the locking effect of the locking assembly 5.

[0100] Further, referring to Figure 6 and Figure 7The shape of the yielding slot 55 is cross-shaped, and the yielding slot 55 comprises two first clamping slots 551 which are mirror images relative to the axis of the rotating shaft 52 and two second clamping slots 552 which are mirror images relative to the axis of the rotating shaft 52. The free end 522 is provided with a clamping plate 57 which extends along the radial direction of the rotating shaft 52. When the limiting piece 4 is in the first position and the rotating shaft 52 is in the fourth position, the clamping plate 57 can be inserted into one of the first clamping slots 551, the shape of the clamping plate 57 is matched with the shape of the first clamping slot 551, and the first clamping slot 551 can limit the clamping plate 57 to prevent the clamping plate 57 and the rotating shaft 52 from rotating, so as to keep the limiting piece 4 in the first position. When the limiting piece 4 is in the second position and the rotating shaft 52 is in the fourth position, the clamping plate 57 can be inserted into one of the second clamping slots 552, and the shape of the clamping plate 57 is matched with the shape of the second clamping slot 552, and the second clamping slot 552 can limit the clamping plate 57 to prevent the clamping plate 57 and the rotating shaft 52 from rotating, so as to keep the limiting piece 4 in the second position.

[0101] By adopting the above technical scheme, the cross-shaped yielding slot 55 can not only limit the clamping plate 57 to prevent the clamping plate 57 and the rotating shaft 52 from rotating, but also facilitate the operator to insert the thumb and the index finger into two first clamping slots 551 or two second clamping slots 552 when pulling the free end 522 of the rotating shaft 52, so as to increase the contact area between the fingers and the rotating shaft 52, thereby facilitating the operator to contact the rotating shaft 52 and reducing the operation difficulty.

[0102] Specifically, the circumferential surface of the side of the rotating shaft 52 close to the free end 522 is provided with a pattern or an anti-skid sleeve.

[0103] By adopting the above technical scheme, the pattern or the anti-skid sleeve can increase the roughness of the outer circumferential surface of the rotating shaft 52, thereby increasing the friction between the outer circumferential surface of the rotating shaft 52 and the fingers of the operator, avoiding the slipping during the gripping process, and making it easier for the operator to adjust the position of the rotating shaft 52.

[0104] When the floating scum in the pool body 1 is cleaned, since the lower surfaces of the scraper 23 and the cleaning block 24 are both provided with the floating plate 25, the scraper 23 and the cleaning block 24 always float on the surface of the seedling raising liquid under the action of the buoyancy, so that the scraper 23 and the cleaning block 24 can be self-adaptively adjusted according to the height of the seedling raising liquid without manual adjustment of the height. The motor 34 is started, the driving shaft of the motor 34 drives the screw rod 33 to rotate, thereby driving the sliding block 32 to reciprocate along the Y direction under the limitation of the sliding groove 31. The sliding block 32 drives the sliding rod 35 provided in the sliding channel 322 and the fixed seat 21, the scraper 23 and the cleaning block 24 fixedly connected with the sliding rod 35 to reciprocate, so that the scraper 23 and the cleaning block 24 abut on the first side wall 111 and the second side wall 112 of the pool body 1 to clean the floating scum attached on the first side wall 111 and the second side wall 112 and to concentrate all the floating scum on the upper surface of the seedling raising liquid. In the process of reciprocating the scraper 23 in the second direction, the scraper 23 scrapes the floating scum on the surface of the seedling raising liquid to the collecting groove 231 through the guide surface 232. The device can conveniently and quickly clean the floating scum on the surface of the seedling raising liquid and the side wall of the pool body, can save manual cleaning, has high efficiency and strong practicality.

[0105] Meanwhile, the limiting piece 4 provided on the upper end of the sliding rod 35 can also be adaptively adjusted according to the use requirement. When the device is in the cleaning state, the limiting piece 4 can avoid the sliding rod 35 from sliding out from below the sliding channel 322 and falling during the process of lowering the liquid level. When it needs to be disassembled after long-time use, the operator respectively puts the thumb and the index finger into the two second clamping grooves 552, then pinches and rotates the rotating shaft 52, pulls the rotating shaft 52 outward, that is, the rotating shaft 52 is adjusted from the fourth position to the third position, so that the clamping plate 57 is pulled out from the first clamping groove 551. Then the limiting piece 4 is rotated to the second position, and the rotating shaft 52 is released. Under the action of the first magnet 53, the second magnet 54 and the second elastic piece 56, the rotating shaft 52 is reset to the fourth position, and the clamping plate 57 is clamped into the second clamping groove 552, so that the state adjustment of the limiting piece 4 is completed. At this time, the worker takes the sliding rod 35 out from the lower opening of the sliding channel 322, so that the sliding rod 35 is separated from the sliding block 32, thereby facilitating the worker to clean the scraper 23, the cleaning block 24 and the collecting groove 231, and to replace and maintain the aging parts such as the floating plate 25.

[0106] When the cleaning and maintenance of the cleaning assembly are completed, the slide rod 35 is reinserted into the sliding channel 322 from the lower opening of the sliding channel 322, and then the operator inserts the thumb and the index finger into the two first clamping grooves 551 and pinches and rotates the rotating shaft 52, and then pulls the rotating shaft 52 outward, so that the clamping plate 57 is pulled out of the second clamping groove 552. After the rotating shaft 52 is adjusted to the third position, the limiting piece 4 is rotated to the first position, the rotating shaft 52 is released, the rotating shaft 52 is reset to the fourth position, and the clamping plate 57 is clamped into the first clamping groove 551. At this time, the limiting piece 4 protrudes from the side wall of the sliding channel 322, so that the slide rod 35 cannot slide out of the sliding channel 322. The device has simple overall structure, convenient operation and use, and high cleaning efficiency.
