Description

Technical Field

[0001] The present invention belongs to the technical field of cultivation soil screening, and specifically relates to a cultivation soil screening device and screening method, and applications in intelligent earthworm breeding. Background Art

[0002] While creating an intelligent constant temperature and humidity breeding space suitable for the growth of earthworms, electronic sensing and intelligent control technologies are used to accurately monitor core elements such as temperature, humidity, and air quality, provide real-time data feedback, and intelligently regulate them, thereby improving the growth quality and reproductive efficiency of earthworms. In order to ensure the normal growth of earthworms, the soil needs to be carefully screened during earthworm breeding to remove impurities and ensure the uniformity of soil particles, so as to avoid poor cleaning effects of impurities such as rotten leaves in the soil, which will affect the quality of the soil and the breeding effect of earthworms.

[0003] A Chinese patent with application number 2021208691573 discloses a soil screening device for earthworm farming, including a base plate, support rods are welded to the four corners of the top of the base plate, and screening boxes are welded to the tops of the support rods. A screening mechanism is arranged inside the screening box. The vibration of the vibration motor of the device can improve the screening capacity of the filter net to prevent the soil from blocking the mesh of the filter net. Some larger debris in the soil can be screened and isolated. The screened debris is discharged from the screening box through the screening plate, reducing the subsequent cleaning work inside the screening box. However, soil with high humidity is prone to clogging and the screening efficiency is low.

[0004] Based on the above scheme, since leaf mold is used for fermentation when cultivating the soil, it is found during screening that some leaf mold is not completely decomposed in the leaf mold. If the humidity of the leaf mold is high, the leaf mold is easy to adhere to the screen drum and cause blockage, affecting the screening efficiency; and more leaf mold will also adhere to the surface of the leaf mold, and the leaf mold is not easy to separate from the leaf mold; since the particles of the leaf mold are easy to stick together, it causes accumulation on the screen drum during feeding, affecting the screening accuracy.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 9 As shown, a cultivation soil screening device of the present invention includes a drum screening assembly 1, transmission assemblies 2 are arranged on both sides of the drum screening assembly 1, and the drum screening assembly 1 includes a fixing frame 101, and a debris removal assembly 3 is arranged on the fixing frame 101.

[0022] like Figures 3 to 5As shown, a plurality of annular frames 102 are arranged on the outer surface of the fixed frame 101, a sieve drum 103 is arranged between two adjacent annular frames 102, a sieve mesh is arranged on the surface of the sieve drum 103, there are four fixed frames 101, and the four fixed frames 101 are evenly arranged in annular shape inside the annular frame 102, a feed baffle 104 is arranged at one end of the fixed frame 101, a discharge ring 105 is arranged at the end of the fixed frame 101 away from the feed baffle 104, a side baffle 106 is arranged on one side of the sieve drum 103, a bottom frame 107 is arranged below the side baffle 106, a lower hopper 108 is arranged inside the bottom frame 107, and a positioning bracket 109 is arranged below the bottom frame 107.

[0023] The transmission assembly 2 includes a rotating shaft 201, which is arranged on one side of the annular frame 102. A roller 203 is arranged on the surface of the rotating shaft 201. A gear transmission mechanism 204 is arranged at one end of the rotating shaft 201. A motor 205 is arranged at the end of the gear transmission mechanism 204 away from the rotating shaft 201. A groove matching the roller 203 is opened on the surface of the annular frame 102. Support seats 202 are arranged on both sides of the roller 203. The support seats 202 are fixedly arranged above the bottom frame 107.

[0024] In order to ensure the quality of the cultivation soil, it is necessary to remove impurities in the soil material to be screened, so as to screen out the required cultivation soil. First, the motor 205 is started. The motor 205 drives the gear transmission mechanism 204 to transmit and rotate the rotating shaft 201. The rotating shaft 201 drives the roller 203 to rotate together. Under the action of friction, the roller 203 drives the annular frame 102 and the screen drum 103 to rotate together. In order to ensure the normal cultivation soil screening work, the rotation speed of the motor 205 is controlled so that the screen drum 103 rotates at a preset speed. The surface of the screen drum 103 is provided with a screen for screening the soil material, and then the soil material to be screened is transported from the feed baffle 104 to Inside the sieve drum 103, as the sieve drum 103 rotates, the soil material moves along the surface of the sieve drum 103, and the soil material gradually moves toward the outlet end of the sieve drum 103 under the action of gravity and the centrifugal force generated by the rotation of the sieve drum 103. In this process, fine material particles pass through the pores of the sieve on the surface of the sieve drum 103 and fall down, and finally enter and are discharged through the lower hopper 108, while larger material particles remain in the sieve drum 103 and continue to move forward until they are discharged from the discharge ring 105, that is, the required soil material is discharged from the lower hopper 108 and collected by the collecting device below the lower hopper 108, and the impurities in the soil material are discharged from the discharge ring 105, thereby achieving the purpose of separating the soil material from the impurities.

[0025] In the above process, it was found that since leaf mold was used for fermentation when cultivating the soil, some leaf mold was found to be not completely decomposed in the leaf mold during screening. If the humidity of the leaf mold is high, the leaf mold will easily adhere to the screen drum 103 and cause blockage, affecting the screening efficiency; and more leaf mold will also adhere to the surface of the leaf mold, and the leaf mold is not easy to separate from the leaf mold; since the particles of the leaf mold are easy to stick together, it will cause accumulation on the screen drum 103 during feeding, affecting the screening accuracy.

[0026] In order to solve the above problems, the cultivation soil screening device also includes: like Figure 5 , Figure 6 As shown, the impurity removal component 3 includes a movable rod 301, which is arranged inside the fixed frame 101, and a cylinder 302 is arranged at one end of the movable rod 301. A plurality of adjustment components are arranged at intervals on the surface of the movable rod 301, and the adjustment component includes a wedge-shaped slider 303, and a wedge-shaped seat 304 is arranged at one end of the wedge-shaped slider 303 away from the fixed frame 101, and a rotating plate 305 is hingedly arranged at one end of the wedge seat 304 away from the wedge slider 303, and a spike 306 is arranged at one end of the rotating plate 305 away from the wedge seat 304, and an arc-shaped scraper 309 adapted to the screen drum 103 is arranged on one side of the wedge-shaped slider 303.

[0027] Two limit seats 307 are arranged on the surface of the fixed frame 101, and the two limit seats 307 are respectively located at the two ends of the wedge-shaped seat 304. A sliding groove is provided at the position where the wedge-shaped seat 304 is connected with the limit seat 307. A limit frame 308 is arranged on the surface of the spike 306, and rotating shafts are arranged at both ends of the limit frame 308. One end of the limit frame 308 is movably connected to the limit seat 307 through the rotating shaft.

[0028] like Figure 7 , Figure 8 As shown, a fixing ring 310 is provided at one end of the spike 306 close to the rotating plate 305, a connecting rod 311 is hingedly provided on one side of the fixing ring 310, a sliding seat 312 is hingedly provided on the end of the connecting rod 311 away from the fixing ring 310, a limiting track 313 is provided on the surface of the sliding seat 312, an elastic spring 314 is provided on the surface of the sliding seat 312, an end of the elastic spring 314 away from the sliding seat 312 is fixedly connected to the limiting track 313, and the limiting track 313 is fixedly provided on the fixing frame 101.

[0029] like Fig. 9As shown, the arc scraper 309 is arranged on the movable rod 301, and the arc scraper 309 is fixedly connected to the surface of the movable rod 301. The wedge-shaped slider 303 is arranged on the movable rod 301, and the wedge-shaped slider 303 is fixedly connected to the surface of the movable rod 301. An elastic member 3041 is arranged at one end of the wedge-shaped seat 304 close to the fixed frame 101. The elastic member 3041 can be made of elastic materials such as springs or elastic ropes. The end of the elastic member 3041 away from the wedge seat 304 is fixedly connected to the fixed frame 101, and a movable groove is provided at the position where the fixed frame 101 is connected to the wedge-shaped slider 303.

[0030] When in use, since there are four fixing frames 101, the four fixing frames 101 are evenly arranged in a ring shape inside the ring frame 102, and the impurity removal component 3 is arranged on the fixing frames 101 (such as Figure 5 As shown in the figure, during the screening process, the fixed frame 101 rotates with the screen drum 103. Due to the effect of gravity, the materials in the screen drum 103 will always be distributed in the direction close to the lower hopper 108. It is worth noting that a gravity sensor is arranged on the fixed frame 101. During the rotation of the fixed frame 101, the output data of the gravity sensor is collected in real time. When the gravity sensor detects that the acceleration component of the fixed frame 101 in the vertical direction reaches the maximum value, the fixed frame 101 is at the lowest point.

[0031] In order to improve the screening effect, when one of the fixed frames 101 rotates to the lowest point, the controller controls the cylinder 302 of the impurity removal component 3 on the fixed frame 101 to extend, and the cylinder 302 pushes the movable rod 301 to move in the direction close to the feed baffle 104, and the movable rod 301 drives the wedge-shaped slider 303 to move along the moving groove on the fixed frame 101. In this process, the elastic member 3041 is stretched, and the wedge-shaped slider 303 squeezes the wedge-shaped seat 304 and makes the wedge-shaped seat 304 move along the limit seat 307 away from the fixed frame 101, and the wedge-shaped seat 304 drives the rotating plate 30 5 and the spikes 306 move together, so that the length of the spikes 306 extending out of the limit frame 308 increases. At this time, the extension of the spikes 306 can not only pierce and collect the humus in the leaf humus on the screen drum 103, but also prevent the humus in the leaf humus from adhering too much to the inside of the screen drum 103 to block the pores on the screen and affect the screening efficiency of the leaf humus, but also break the particles bonded in the leaf humus, break and separate the larger particles bonded, and facilitate the subsequent screening thereof. With the rotation of the screen drum 103, the leaf humus moves inside the screen drum 103, so that the spikes 306 can achieve the effect of stirring the leaf humus.

[0032] In the above process, the arc scraper 309 moves with the movable rod 301, so that the arc scraper 309 pushes the leaf mold along the inner wall of the screen cylinder 103 toward the feed baffle 104, thereby disturbing the leaf mold, thereby avoiding excessive accumulation of leaf mold in local positions of the screen cylinder 103 and improving the service life and screening accuracy of the screen cylinder 103.

[0033] It is worth noting that when the wedge-shaped seat 304 drives the rotating plate 305 and the spike 306 to move in a direction away from the fixed frame 101, the fixed ring 310 moves with the spike 306, the elastic spring 314 is stretched, the fixed ring 310 drives the connecting rod 311 and the slide 312 to move together, and the slide 312 moves along the limiting track 313 toward the limiting seat 307. During this process, the angle of the spike 306 does not change.

[0034] Then, as the screen drum 103 rotates, the position of the fixed frame 101 rises from the lowest point. For the convenience of description, the fixed frame 101 is the first fixed frame 101. In this process, in order to prevent the rotten leaves from falling off the spikes 306, the controller controls the cylinder 302 to continue to extend. Under the action of the cylinder 302, the wedge seat 304 drives the rotating plate 305 and the spikes 306 to move away from the fixed frame 101. In this process, the fixed ring 310 moves with the spikes 306, the elastic spring 314 is stretched, and the fixed ring 310 drives the connecting rod 311 and the sliding seat 312 moves together, and the slide 312 moves along the limiting track 313 towards the limiting seat 307. When the stretching amount of the elastic spring 314 reaches the maximum, the slide 312 stops on the limiting track 313. When the spike 306 continues to move forward, the limiting frame 308 rotates under the action of the connecting rod 311. At this time, the limiting frame 308 drives the spike 306 and the rotating plate 305 to move together, so that the spike 306 is deflected towards the limiting track 313, thereby hooking the rotten leaves on the spike 306 to prevent the rotten leaves from falling along the spike 306.

[0035] At this time, the fixed frame 101 at the position adjacent to the first fixed frame 101 moves toward the lowest point, that is, when the second fixed frame 101 moves toward the lowest point, the controller controls the impurity removal component 3 on the second fixed frame 101 to reciprocate. Specifically, the controller controls the cylinder 302 to drive the movable rod 301 to reciprocate and retract, so that the movable rod 301 drives the arc scraper 309 to reciprocate and push the leaf mold in the screen drum 103, thereby accelerating the movement of the leaf mold in the screen drum 103. Under the stirring action of the arc scraper 309, the leaf mold is dispersed and evenly spread in the screen drum 103. At the same time, under the action of friction, the leaf mold or other impurities adhering to the inner wall of the screen drum 103 can fall off, thereby improving the screening efficiency of the screen drum 103. At the same time, the arc scraper 309 on one end of the screen drum 103 close to the discharge ring 105 can also collide with the material at this position, thereby causing the leaf mold adhering to the impurities to fall off, avoiding waste, and accelerating the movement speed of impurities in the screen drum 103.

[0036] At the same time, during the reciprocating motion of the wedge-shaped slider 303, the wedge-shaped seat 304 reciprocates along the limit seat 307. During this process, the wedge-shaped seat 304 drives the rotating plate 305 and the spikes 306 to reciprocate together, so that the spikes 306 extend and contract on the limit frame 308, thereby turning over the leaf mold in the screen cylinder 103, and breaking up the stuck leaf mold to improve the screening accuracy.

[0037] As the screen drum 103 rotates, when the first fixed frame 101 is about to move to the highest point, the spike 306 on the impurity removal component 3 on the first fixed frame 101 is controlled to shrink. Specifically, the controller controls the cylinder 302 to shrink, and the movable rod 301 drives the wedge-shaped slider 303 to move along the movable groove on the fixed frame 101 in the direction away from the feed baffle 104. Under the action of the elastic member 3041, the wedge-shaped seat 304 moves on the limit seat 307 in the direction close to the fixed frame 101. Under the action of the wedge seat 304, the rotating plate 305 drives the spike 306 and the limit frame 308 to move together, so that the deflection angle of the spike 306 is restored to the initial state, and then The rear controller continues to control the cylinder 302 to contract, thereby reducing the length of the spike 306 extending out of the limit frame 308. During the contraction of the spike 306, the rotten leaves on the spike 306 are blocked by the limit frame 308 and fall off. Under the centrifugal force of the rotation of the screen drum 103, the rotten leaves fall toward the discharge ring 105. At this time, the fixed frame 101 at the relative position to the first fixed frame 101 is the third fixed frame 101. At this time, the controller controls the spike 306 in the impurity removal component 3 on the third fixed frame 101 to extend, thereby piercing and collecting the fallen leaves that fall into the leaf mold. The specific operation refers to the operation of the first fixed frame 101 at the lowest point, and no further details are given here.

[0038] Then, the fourth fixing frame 101 is located opposite to the second fixing frame 101. The controller controls the spike 306 on the impurity removal component 3 on the fourth fixing frame 101 to deflect to a preset angle. The specific operation is that the controller controls the cylinder 302 to extend, and the cylinder 302 pushes the movable rod 301 to move toward the direction close to the feed baffle 104. The movable rod 301 drives the wedge-shaped slider 303 and makes the wedge-shaped slider 303 move along the moving groove on the fixing frame 101. In this process, the elastic member 3041 The wedge-shaped slider 303 squeezes the wedge-shaped seat 304 and makes the wedge-shaped seat 304 move along the limit seat 307 in the direction away from the fixed frame 101. The wedge-shaped seat 304 drives the rotating plate 305 and the spike 306 to move together, so that the length of the spike 306 extending out of the limit frame 308 increases, and then the cylinder 302 continues to extend. Under the action of the cylinder 302, the wedge-shaped seat 304 drives the rotating plate 305 and the spike 306 to move together in the direction away from the fixed frame 101. In this process In the embodiment, the fixing ring 310 moves with the spike 306, the elastic spring 314 is stretched, the fixing ring 310 drives the connecting rod 311 and the slide 312 to move together, and the slide 312 moves along the limiting track 313 toward the limiting seat 307. When the stretching amount of the elastic spring 314 reaches the maximum, the slide 312 stops on the limiting track 313. When the spike 306 continues to move forward, the limiting frame 308 rotates under the action of the connecting rod 311. The limiting frame 308 drives the spikes 306 and the rotating plate 305 to move together, so that the spikes 306 are deflected in the direction close to the limiting track 313, so that the spikes 306 are deflected by a preset angle. At this time, the spikes 306 are tilted on the screen drum 103, and because the screen drum 103 is in an inclined state, the leaf mold will collide with the inclined spikes 306 when moving along the surface of the screen drum 103, and the spikes 306 will collect the leaf mold in the leaf mold along the radial direction of the screen drum 103.

[0039] It is worth noting that during the rotation of the screen drum 103, the operation steps of the first fixed frame 101 and the third fixed frame 101 are performed alternately. Through the different movement states of the impurity removal components 3 on the four fixed frames 101, it is possible to remove excess impurities and leaf mold during the leaf mold screening process, thereby improving the screening efficiency.

[0040] The present invention also provides a screening method for a cultivation soil screening device, and the specific screening method steps are as follows: S1: First, the transmission assembly 2 is set to rotate the screen drum 103 on the drum screening assembly 1 at a preset speed, and then the soil material to be screened is transported to the inside of the screen drum 103 for screening; S2: Secondly, as the screen drum 103 rotates, the soil material moves along the surface of the screen drum 103, and the soil material gradually moves toward the outlet end of the screen drum 103 under the action of gravity and the centrifugal force generated by the rotation of the screen drum 103; S3: Then, the soil material on the sieve drum 103 is turned over by setting the impurity removal component 3, and the rotten leaves and impurities in the soil material are collected to prevent the rotten leaves from adhering to the sieve drum 103 and affecting the screening efficiency; S4: Finally, under the action of the screen on the surface of the screen drum 103, the fine material particles pass through the pores of the screen and fall down, while the larger material particles remain in the screen drum 103 and continue to move forward until they reach the outlet end and are discharged.

[0041] The invention discloses an application of a cultivation soil screening device in intelligent earthworm breeding, specifically used for screening cultivation soil in intelligent earthworm breeding. Through the cooperation of a drum screening component and an impurity removal component, the problems of low leaf mold screening efficiency and incomplete impurity cleaning in the prior art are solved, thereby screening out high-quality cultivation soil, creating a better environment for the growth of earthworms, and improving the growth quality and reproductive efficiency of earthworms.
