Description

Technical Field

[0001] The utility model relates to the technical field of seedling cultivation soil production, in particular to special soil production equipment for seedling cultivation. Background Art

[0002] Soil preparation for rice seedlings is a crucial link in the rice seedling process, which directly affects the quality and yield of the seedlings. The soil for seedlings should have high water and fertilizer retention capabilities, as well as a certain permeability to facilitate the retention and supply of water and nutrients. Therefore, in the process of making soil for seedlings, local soil is mixed with rice husks, organic fertilizers, etc. After the local soil is dug, there are often more caked lumps in the soil, which will result in the soil not being able to be fully mixed.

[0003] The Chinese invention patent with announcement number: CN107998921A discloses a seedling soil fertilization mixing device. This device overcomes the problems of traditional seedling soil fertilization mixing devices, which use traditional solid waste, resulting in uneven mixing during mixing, and difficulty in uniform mixing, making mixing difficult and the process time long. It improves the traditional seedling soil fertilization mixing device, which uses traditional solid waste, resulting in uneven mixing during mixing, and difficulty in mixing, and even motor jamming.

[0004] The above device is improved by mixing the soil with the fertilization device, but does not take into account the caking or hard dry soil in the soil, and the preparation work before use. At the same time, in the existing soil crushing work, either a crusher is used to process the soil, and the soil processed in this way is too fine, resulting in the problem of soil clumping after mixing, which is not conducive to the growth of seedlings.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] like Figure 1 and Figure 2 As shown, a special soil making equipment for seedling cultivation includes a base 101, on which a conveyor belt is provided for collecting soil to a certain place, and a classification chamber 103 is fixedly installed on the base 101, in which a rotating rod 105 is rotatably installed, and a plurality of stirring filters are provided on the rotating rod 105 for preliminary screening of the soil, and a soil inlet is provided on the end of the classification chamber 103 away from the base 101, a fine soil channel 102 is fixedly installed on one side of the classification chamber 103, and a coarse soil channel 104 is fixedly installed on the other side of the classification chamber 103, and the fine soil channel 102 is fixedly connected to the coarse soil channel 104, and the rotating rod 105 can divide the soil into two categories through the stirring filter when rotating, one category enters the fine soil channel 102 and falls from the fine soil channel 102 to the base 101, and the other category enters the coarse soil channel 104 for subsequent work.

[0020] like Figures 2 to 4As shown, a crushing tank 106 is also fixedly mounted on the base 101. The crushing tank 106 is tilted on the base 101, and the tilt angle of the crushing tank 106 relative to the base 101 is 20 degrees. The crushing tank 106 is fixedly connected to the rough soil channel 104. A main motor 201 is fixedly mounted on the outer wall of the crushing tank 106. A motor gear 202 is fixedly mounted on the output shaft of the main motor 201. A capping gear 203 is rotatably mounted on the crushing tank 106. The capping gear 203 is rotatably mounted on the motor gear 202. The capping gear 203 and the crushing tank 106 are meshed, and form a crushing chamber. A sub-motor 204 is fixedly installed on the side of the capping gear 203 away from the base 101. A stirring shaft 205 is fixedly installed on the output shaft of the sub-motor 204. The stirring shaft 205 is arranged in the crushing chamber. A stirring claw is also arranged in the stirring shaft 205. The stirring claw is L-shaped. When the stirring shaft 205 rotates around the output shaft of the sub-motor 204 in the crushing chamber, the stirring claw of the stirring shaft 205 can contact the inner wall of the crushing tank 106.

[0021] like Figures 2 to 4 As shown, a fixing plate 207 is fixedly installed on the capping gear 203, and the fixing plate 207 is located in the crushing chamber. A stirring ring 209 is rotatably installed at one end of the crushing tank 106 away from the capping gear 203, and the stirring ring 209 is fixedly connected to the fixing plate 207. An extrusion plate 206 is slidably installed on the capping gear 203, and a plurality of extrusion springs 210 are fixedly installed on the extrusion plate 206. The other end of the extrusion spring 210 is fixedly connected to the fixing plate 207. The extrusion plate 206 can contact the stirring claw on the stirring shaft 205, and a plurality of large filter holes are provided on the extrusion plate 206. The fixed plate 207 is provided with a plurality of small filter holes, and the large filter holes on the extrusion plate 206 are twice as large as the small filter holes on the fixed plate 207. This is to allow the soil to enter between the extrusion plate 206 and the fixed plate 207, and then the soil blocks are crushed by the collision between the extrusion plate 206 and the fixed plate 207. An outlet mesh plate 208 is fixedly installed at one end of the crushing tank 106 away from the capping gear 203, and a plurality of discharge holes are provided on the outlet mesh plate 208. The soil in the crushing tank 106 passes through the extrusion plate 206 and the fixed plate 207 and then falls out of the crushing chamber from the discharge holes on the outlet mesh plate 208.

[0022] When the device is working, soil needs to be put into the classification chamber 103 from the soil entrance on the classification chamber 103, and then the rotating rod 105 is started to rotate. Figure 2The rotating rod 105 rotates counterclockwise, and when the rotating rod 105 rotates, the soil will first fall onto the stirring filter, allowing the stirring filter to perform preliminary coarse filtration on the soil, allowing the finer particles in the soil to directly fall into the fine soil channel 102, and then be collected by the conveyor belt on the base 101. The soil particles that do not pass through the stirring filter will be sent to the coarse soil channel 104, and then fall from the coarse soil channel 104 into the crushing chamber on the crushing tank 106.

[0023] After the soil enters the crushing tank 106, the auxiliary motor 204 is started, and the auxiliary motor 204 drives the stirring shaft 205 to rotate in the crushing chamber, so that the stirring shaft 205 can continuously hit the soil particles in the crushing chamber, thereby reducing the diameter of the soil particles, and the stirring shaft 205 will continuously collide with the extrusion plate 206 while rotating, so that the extrusion plate 206 continuously moves toward the fixed plate 207, so that the soil particles between the extrusion plate 206 and the fixed plate 207 can be squeezed and crushed, and only when the soil can pass through the small filter holes on the fixed plate 207, the soil can leave the space between the fixed plate 207 and the extrusion plate 206, and then the soil falls out of the crushing chamber through the outlet mesh plate 208 and enters On the conveyor belt on the base 101, when the device needs to quickly clean a large amount of soil, the auxiliary motor 204 and the motor gear 202 can be started at the same time, so that the motor gear 202 drives the sealing gear 203 to rotate. When the sealing gear 203 rotates, the sealing gear 203 will drive the stirring shaft 205, the extrusion plate 206, the fixed plate 207, and the stirring ring 209 to rotate around the axis of the crushing tank 106, so that the stirring shaft 205 can rotate around the crushing tank 106 while rotating, so that the soil in the crushing chamber can continuously hit the stirring shaft 205, the extrusion plate 206, and the fixed plate 207, so that the soil is quickly crushed, and then the soil falls out of the crushing chamber from the outlet mesh plate 208.
