Description

Technical Field

[0001] The invention relates to the technical field of experimental instruments, in particular to a worm composting pot capable of screening and counting. Background Art

[0002] When earthworms are concentrated in a compost tank and a certain number of them need to be taken out for later experiments, the compost tank is usually opened to expose the compost to the outside, and then the required number of earthworms are manually turned over to pick up the required number of earthworms. Since the line of sight inside the compost is poor, it is easy to pick up earthworms because of their smooth surface, which makes the operation more difficult. Therefore, the prior art uses light to drive and guide the earthworms in the compost to separate themselves from the compost to the collection chamber before taking them out.

[0003] Although the above-mentioned driving method can solve the problem of driving and separating earthworms, it is often used in open experimental boxes. When used for earthworms in sealed composting tanks, due to the high light-shielding properties of the sealed composting tanks themselves and the high sealing requirements of their tube bodies, it is impossible to meet the visibility of the number of earthworms after guidance while meeting the tank body sealing requirements. At the same time, after each earthworm is taken out, due to the visibility of the composting tank, it is impossible to know whether the earthworms have returned to the sealed composting tank. For this reason, we propose a sieveable and countable earthworm composting tank. Summary of the invention

[0004] The main purpose of the invention is to provide a vermicomposting pot capable of screening and counting.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A worm composting tank capable of screening and counting includes a composting tank and a screening bottom shell tank, wherein a light guide column is installed in the composting tank, and a flushing liquid supply part and a module for counting earthworms passing through the screening bottom shell tank are installed in the screening bottom shell tank. A bottom channel closing assembly is provided in the composting tank, and a center screening assembly for temporarily collecting earthworms to be counted is fixedly installed on the inner side of the screening bottom shell tank. The bottom channel closing assembly includes a channel branch, a path limiting pin and an isolation plug, wherein the isolation plug is located on the inner side of the channel branch and is used to close the channel branch when not screening, thereby realizing independent sealing of the composting tank. The path limiting pin is fixedly connected to the inner wall of the channel branch, and the isolation plug is slidably connected to the path limiting pin. The central screening assembly includes a return guide plate, a return guide plate and a docking channel end, the return guide plate and the return guide plate are both fixedly connected to the screening bottom shell tank, and the docking channel end is snap-connected to the top of the return guide plate to push the isolation plug after the compost main tank and the screening bottom shell tank are engaged.

[0007] A further improvement of the present invention is that an isolation mesh plate and a transfer guide plate are fixedly connected to the inner cavity of the compost main tank, and the channel branch pipe is fixedly connected to the inner wall of the transfer guide plate.

[0008] A further improvement of the present invention is that the top wall of the transfer guide plate is fixedly connected with a ring-side lighting lamp bead, which is used to guide the earthworms to move inside the ring-side lighting lamp bead after they reach the position of the transfer guide plate.

[0009] A further improvement of the present invention is that an elastic wall-adhering ring for increasing the degree of fit with the isolation plug is fixedly connected to the inner side of the channel branch pipe, and a statistical trigger module is fixedly connected to the isolation plug.

[0010] A further improvement of the present invention is that the earthworm counting module is arranged on the inner side of the end of the docking channel, a plurality of return lighting lamps distributed in an annular pattern are arranged on the inner side of the return guide disk, and a liquid guiding convex head for flushing water is arranged at the center of the return guide disk. The screening bottom shell tank is fixedly connected to the liquid flow orifice plate, and a weighing module is arranged at one end of the inner side of the return guide disk.

[0011] A further improvement of the present invention is that an embedded buckle plate is fixedly connected to the top wall of the screening bottom shell tank, and the embedded buckle plate is slidably connected to the compost main tank, and is used for slidingly guiding the engagement of the compost main tank and the screening bottom shell tank when counting and collecting earthworms.

[0012] A further improvement of the present invention is that the steps of using a sieving and counting earthworm composting tank include the following steps:

[0013] Step S1, placing the screening bottom shell tank at the bottom of the compost main tank, and pushing the embedded buckle plate into the inner side of the compost main tank to achieve mutual engagement of the compost main tank and the screening bottom shell tank, so that the compost main tank and the screening bottom shell tank are kept in a sealed state when the earthworms are screened and counted;

[0014] Step S2, after the compost main tank and the screening bottom shell tank are connected, the end of the docking channel slides with the screening bottom shell tank toward the inner side of the channel branch pipe, and then pushes the isolation plug upward until the isolation plug is pushed away from the inner side of the channel branch pipe, and the channel branch pipe is opened. At this time, the statistical trigger module receives a contact signal from the end of the docking channel, that is, the screening and guiding of earthworms is started in a sealed state;

[0015] Step S3, after the screening guide is started, the earthworms located at the upper end of the transfer guide plate are driven by the illumination of the ring side lighting beads, and then move to the inner side of the return guide plate through the channel branch pipe and the connecting position of the docking channel end. After that, the earthworms are screened, counted and weighed through the counting module and the weighing module.

[0016] Compared with the prior art, the present invention engages the compost material main tank and the screening bottom shell tank by snapping them together, so that the end of the docking channel slides with the screening bottom shell tank to enter the inner side of the channel branch pipe, and then pushes the isolation plug upward, and the channel branch pipe is opened when the compost material main tank and the screening bottom shell tank are engaged with each other in a closed state. At the same time, the statistical trigger module is triggered by the contact pressure signal of the docking channel end, and the ring side lighting lamp beads are synchronously turned on, so that the earthworms are guided to the inner side of the screening bottom shell tank through the trunk in a sealed state, and the rapid screening is completed.

[0017] Compared with the prior art, the present invention can separate the screening bottom shell tank from the main compost tank after the earthworms are guided to the inside of the screening bottom shell tank, so that the isolation plug is no longer pushed by the end of the docking channel after the main compost tank and the screening bottom shell tank are disengaged, and then returns to the inside of the channel branch pipe. At this time, the operator selects the earthworms collected in the screening bottom shell tank while maintaining visibility, while maintaining the closedness of the main compost tank. When the main compost tank and the screening bottom shell tank are returned to their positions to guide the earthworms back to the position in the main compost tank, the weighing module can be used to know whether there are residual earthworms in the screening bottom shell tank that have not returned to the main compost tank, thereby effectively adapting to the use of compost tanks with poor visibility and sealing requirements.

[0025] In this embodiment, a flap is provided on the top of the compost tank 1. When filling the compost and earthworms, the flap is opened to place the compost and earthworms inside the compost tank 1, and then the flap is closed to seal the compost tank 1. After the earthworms and the compost are placed inside the cavity of the compost tank 1, the compost and earthworms are isolated in the storage cavity formed between the isolation mesh plate 11 and the compost tank 1.

[0026] In this embodiment, when the compost body is placed in the compost main tank 1 and the number of earthworms needs to be sorted in a sealed state, the operator only needs to place the screening bottom shell tank 2 at the bottom of the compost main tank 1, and then push the embedded buckle plate 22 into the inner side of the compost main tank 1. After the embedded buckle plate 22 is pushed into the inner side of the compost main tank 1, the docking channel end 43 moves to the inner side of the channel branch 31 along the active path of the screening bottom shell tank 2, and then the isolation plug 33 is pushed by the docking channel end 43 and moves along the sliding path of the path limiting pin 32, until the embedded buckle plate 22 is completely placed in the inner side of the compost main tank 1, and the isolation plug 33 is pushed by the docking channel end 43 to separate from the inner side of the channel branch 31. At this time, the compost main tank 1 and the screening bottom shell tank 2 are connected and closed, and the channel of the channel branch 31 for the movement of earthworms when driving is connected to the docking channel end 43.

[0027] After the main compost tank 1 and the screening bottom shell tank 2 are connected and sealed, and the docking channel end 43 is connected to the channel branch pipe 31, the statistical trigger module 34 is contacted and squeezed by the docking channel end 43, thereby triggering the earthworm driving collection signal, so that the illumination guide column 6 and the ring side illumination lamp bead 13 are synchronously turned on. At this time, the earthworms in the main compost tank 1 are driven by light to pass through the isolation hole mesh plate 11, and after reaching the docking channel end 43, they are counted by the earthworm passing counting module 5, and finally reach the position between the return guide disk 41 and the return guide disk 42 inside the screening bottom shell tank 2, completing the earthworm screening.

[0028] In this embodiment, a reset spring can be fixed between the isolation plug 33 and the path limiting pin 32 to reset the isolation plug 33 when it is re-inserted into the inner side of the channel branch 31 after the compost main tank 1 and the screening bottom shell tank 2 are separated. After the earthworms are concentrated on the inner side of the return guide disk 41 and the return guide disk 42, when the operator needs to take the earthworms out for selection, the embedded buckle plate 22 can be pulled out from the inner side of the compost main tank 1 to separate the screening bottom shell tank 2 and the compost main tank 1. During the separation process, the docking channel end 43 is pulled out from the inner side of the channel branch 31 along with the movement of the screening bottom shell tank 2, so that when the isolation plug 33 is no longer subjected to the thrust of the docking channel end 43, it re-reaches the inner side of the channel branch 31 due to the retraction of the reset spring. In the current state, the compost main tank 1 and the screening bottom shell tank 2 are separated, and the channel branch pipe 31 is again sealed and isolated by the isolation plug 33, so as to always maintain the required sealing property of the compost main tank 1. After the screening bottom shell tank 2 and the compost main tank 1 are separated, the earthworms inside the return guide disk 41 can be selected by removing the docking channel end 43 from the upper end of the return guide disk 42 in a visible state.

[0029] Among them, the inner cavity of the compost main tank 1 is fixedly connected with an isolation hole mesh plate 11 and a transfer guide plate 12, and the channel branch pipe 31 is fixedly connected to the inner wall of the transfer guide plate 12; in this embodiment, the transfer guide plate 12 is placed at the bottom of the compost main tank 1 to form an independent closed cavity inside the compost main tank 1, which is used for sealed storage of earthworms and compost, and the isolation hole mesh plate 11 is used to block the compost when driving and screening the earthworms.

[0030] Among them, the top wall of the transfer guide plate 12 is fixedly connected with a ring side lighting lamp bead 13, which is used to guide the earthworms to travel inside the ring side lighting lamp bead 13 after they reach the position of the transfer guide plate 12; the ring side lighting lamp bead 13 is arranged at the top side position of the transfer guide plate 12, and is used to cooperate with the earthworms to drive the earthworms through the counting module 5, so that the earthworms can quickly drill down to the return guide disk 41 and the inner side of the return guide disk 42 through the connecting point of the docking channel end 43 and the channel branch pipe 31 due to the influence of light.

[0031] The inner side of the channel branch pipe 31 is fixedly connected with an elastic wall-adhering ring 311 for increasing the fit with the isolation plug 33, and the isolation plug 33 is fixedly connected with a statistical trigger module 34; the elastic wall-adhering ring 311 is intended to increase the fit when the isolation plug 33 is located inside the channel branch pipe 31. The statistical trigger module 34 is electrically connected with the light guide column 6 and the transfer guide plate 12, and then when it is pushed into the inner side of the channel branch pipe 31 on the docking channel end 43 and the isolation plug 33 is pushed up, it contacts the statistical trigger module 34 at the bottom of the isolation plug 33, and then the compost material main tank 1 and the screening bottom shell tank 2 are sealed with each other, and then the light guide column 6 and the transfer guide plate 12 are automatically triggered to drive the earthworms, thereby improving the smoothness of the earthworm screening operation.

[0032] Among them, the top wall of the screening bottom shell tank 2 is fixedly connected with an embedded buckle plate 22, and the embedded buckle plate 22 is slidably connected with the compost main tank 1, and is used for sliding guidance of the joint of the compost main tank 1 and the screening bottom shell tank 2 when counting and collecting earthworms; the bottom side of the compost main tank 1 is provided with a card slot that is adapted to the embedded buckle plate 22, and the screening bottom shell tank 2 and the compost main tank 1 are joined by inserting the embedded buckle plate 22 into the inner side of the card slot, so that the compost main tank 1 and the screening bottom shell tank 2 are in a relatively sealed state after being combined, thereby achieving the purpose of keeping the compost main tank 1 in the required sealing state at all times.

[0033] Example 2

[0034] The similarities between this embodiment and the first embodiment are not described in detail, but the differences between this embodiment and the first embodiment are that the earthworm counting module 5 is arranged on the inner side of the docking channel end 43. A plurality of return lighting lamps 411 arranged in a circular pattern are arranged on the inner side of the return guide plate 41, and a liquid guiding protrusion 412 for flushing water is arranged at the center of the return guide plate 41. The screening bottom shell tank 2 is fixedly connected to the liquid flow orifice plate 44, and a weighing module 45 is arranged at one end of the inner side of the return guide plate 42.

[0035] In this embodiment, after the compost main tank 1 and the screening bottom shell tank 2 are separated and the earthworms inside the return guide disk 41 and the return guide disk 42 are selected, the power supply of the illumination guide column 6 and the transfer guide plate 12 is disconnected, and the compost main tank 1 and the screening bottom shell tank 2 are reconnected, at which time the docking channel end 43 and the channel branch pipe 31 are in a conducting state again. After the conduction, the device is inverted as a whole, so that the compost main tank 1 is located at the bottom and the screening bottom shell tank 2 is located at the top position, and the return illumination lamp 411 is turned on at this time, so that the earthworms inside the return guide disk 41 are driven by the return illumination lamp 411, and re-enter the interlayer position of the isolation mesh plate 11 and the transfer guide plate 12 through the connecting point of the docking channel end 43 and the channel branch pipe 31, and finally re-inserted into the compost body at the upper end of the isolation mesh plate 11 through the through hole end of the isolation mesh plate 11. At the same time, the weighing module 45 disposed on the inner side of the return guide disc 41 can feedback the weight of the earthworms at the position of the return guide disc 42, thereby determining whether the earthworms have completed the return to the compost body. After the return is completed, the compost material main tank 1 and the screening bottom shell tank 2 are rearranged in an upright state, and the return guide disc 41 is flushed by drawing external water through the flushing liquid supply part 21 (a micro water pump connected to an external water source in this embodiment), so that the water flows downward through the aperture of the return guide disc 41 and the aperture of the liquid flow orifice plate 44 through the inclined guidance of the liquid guide protrusion 412 until it reaches the bottom position of the screening bottom shell tank 2, and then the bottom valve of the screening bottom shell tank 2 can be opened to discharge the water, and then the inside is cleaned for the next screening.
