Description

Technical Field

[0001] The utility model belongs to the technical field of mixing machinery, and particularly relates to an organic compound fertilizer mixing device for improving rice yield. Background Technique

[0002] Organic compound fertilizer is a commonly used compound fertilizer in rice planting. It is obtained by mixing the fermented natural fertilizer as the base fertilizer with elemental nutrient fertilizers such as phosphate fertilizer, nitrogen fertilizer, and potassium fertilizer in proportion. According to the growth requirements of different rice varieties, reasonably adjusting the content of each element in the compound fertilizer can help improve the rice yield. In the preparation process of organic compound fertilizer, the process of fully mixing the base fertilizer with elemental nutrient fertilizers such as phosphate fertilizer, nitrogen fertilizer, and potassium fertilizer to form the compound fertilizer base material is very important. The compound fertilizer base material still needs to go through processes such as drying and granulation before it can become the organic compound fertilizer sold in the market. Therefore, the mixing uniformity of the compound fertilizer base material directly determines the product quality of the organic compound fertilizer. The traditional vertical mixing device usually relies on a single-structure paddle to rotate circumferentially in the mixing cylinder to drive the base fertilizer powder and elemental fertilizer powder falling into the mixing cylinder for mixing. The disadvantage of this stirring and mixing is that the single-structure paddle can only provide a stirring force in one direction, making it difficult to ensure the full mixing of the base fertilizer and elemental fertilizer, resulting in poor uniformity of the compound fertilizer base material after mixing and affecting the use effect of the fertilizer. Therefore, based on the above problems, an organic compound fertilizer mixing device for improving rice yield is developed. Content of the Utility Model

[0017] The beneficial effects of the present application compared with the prior art:

[0018] The purpose of the present utility model is to provide an organic compound fertilizer mixing device for increasing rice yield. Compared with the traditional vertical mixing device, the structure of the mixing components in the mixing unit is optimized. The rotation structure of the mixing components in this application is divided into three parts. The upper part is the material distribution component. Considering the feeding structure with feeding from both sides in this application, the material distribution component can drive the base fertilizer powder and elemental fertilizer powder entering the barrel from both sides to move circumferentially, which is beneficial to improving the uniformity of material falling. The middle part is the stirring part composed of multiple stirring and mixing components. The stirring paddles in this application are divided into two types, namely the upward-inclined stirring paddle and the downward-inclined stirring paddle. The upward-inclined stirring paddle and the downward-inclined stirring paddle can provide stirring forces in two stirring directions during rotation, promoting the up-and-down exchange of the fluid, and making the stirring effect more sufficient. Among them, the downward-inclined stirring paddle can provide a component force to push the powder downward during rotation, and the upward-inclined stirring paddle can provide a component force to push the powder upward during rotation. Under the action of the gravity of the powder, the powder as a whole still moves downward, which can ensure that the powder is smoothly discharged from the bottom of the barrel. During the stirring process, the base fertilizer powder and the elemental fertilizer powder alternately contact the two paddles, enabling full mixing during the rotation of the paddles. And this structure can also effectively avoid problems such as the deformation of the main shaft and the paddles during the cooling process of the stirring structure. The lowermost part is the spiral guiding part, which is correspondingly arranged with the conical part of the barrel. The spiral guiding structure can effectively alleviate the powder blocking phenomenon caused by the reduction of the barrel diameter, and is more conducive to the discharged mixed powder along the discharge port of the barrel.

[0019] The purpose of the present utility model is to provide an organic compound fertilizer mixing device for increasing rice yield, and a base fertilizer guiding unit and a major element nutrient guiding unit are also added, which are respectively used to guide the base fertilizer and the elemental fertilizer into the barrel. And sliding mechanisms are arranged between the base fertilizer guiding unit and the major element nutrient guiding unit and the support bracket. The feeding ports of the traditional vertical mixing devices are directly docked with the feeding devices of the base fertilizer or the elemental fertilizer. The disadvantage of doing this is that if you want to maintain and repair the inside of the vertical mixing device, then you need to remove the top cover of the barrel from the top, and then the staff enters the barrel from the top of the barrel for maintenance work. Then, because there are also feeding devices for the base fertilizer or the elemental fertilizer above the barrel, this results in a large number of components that need to be adjusted for one maintenance, greatly affecting the maintenance efficiency. Through the setting of the guiding unit in this application, the feeding devices of the base fertilizer or the elemental fertilizer and the barrel can be arranged in a staggered manner, and the guiding unit is used as the transfer unit for the powder. When the barrel needs to be overhauled, the two guiding units can slide on the bracket in the direction away from the mixing unit, providing sufficient working space for the overhaul of the top of the mixing barrel, and can greatly improve the overhaul and maintenance efficiency of the mixing device.

[0020] The purpose of the present utility model is to provide an organic compound fertilizer mixing device for increasing rice yield. In the large element nutrient guiding unit, a separate flow regulation structure design is carried out for the discharge end of each element fertilizer. The lifting electric cylinder can drive the flow regulation block to move longitudinally in the discharge pipe to adjust the passage size between the large element nutrient guiding pipe and the corresponding discharge pipe. When the flow regulation block completely disengages from the interface between the guiding pipe and the corresponding discharge pipe, the discharge flow rate is the largest at this time. Along with the increase in the blocking component of the flow regulation block to the interface, the discharge flow rate gradually decreases until the interface is completely blocked by the flow regulation block and the discharge stops. Such a setting takes into account that the proportion of each element fertilizer in different compound fertilizers is different. Through this structural design, the flow rate of a certain element fertilizer within a fixed time can be adjusted, that is, the dosage of the element fertilizer within a fixed time is adjusted, thereby simply and efficiently adjusting the mixing ratio of single elements in the compound fertilizer.

[0046] It will be described in combination with Embodiments 5 to 7. By adding the sliding mechanism 5, it is convenient to adjust the working positions of the basal fertilizer guiding unit and the macronutrient guiding unit, providing sufficient working space for the staff to repair the material cylinder 24. The sliding mechanism 5 mainly consists of a sliding plate 53 and multiple pulleys 55 to form a supporting structure. The push rod motor 52 serves as a power component to push the sliding plate 53 to move reciprocally, making it close to or away from the mixing unit. To ensure the accuracy of the working positions of the basal fertilizer guiding unit and the macronutrient guiding unit during the guiding work, a limiting plate 27 is also provided on the tops of the macronutrient guiding unit bracket 3 and the basal fertilizer guiding unit bracket 4 to determine the limit positions of the extended movement of the sliding mechanism 5.

[0047] Embodiment 8: In combination with Figures 1 to 10 This embodiment will be described. The difference between this embodiment and Embodiment 7 is that the material distribution component 21 includes a first mounting sleeve 211, an outer ring 212, and multiple material distribution blades 213. The first mounting sleeve 211 is sleeved on the upper part of the rotating shaft, the outer ring 212 is sleeved outside the first mounting sleeve 211, and multiple material distribution blades 213 are arranged equidistantly in the circumferential direction between the first mounting sleeve 211 and the outer ring 212.

The other compositions and connection relationships are the same as those in Embodiment 7.

[0048] In this embodiment, when applying this application, a feeding structure with injection from both sides is adopted. The material distribution component 21 can drive the basal fertilizer powder and elemental fertilizer powder entering the material cylinder from both sides to move circumferentially, which is beneficial to improving the uniformity of material dropping. Generally, there are 20 - 24 blades for the material distribution blades 213, and the inclination angle of each material distribution blade 213 is 5 - 9°. With such settings, it can ensure that there is enough material dropping gap between two adjacent material distribution blades 213, avoiding the powder from accumulating on the inner side of the blades under the action of centrifugal force when the material distribution component 21 rotates.

[0049] Embodiment 9: In combination with Figures 1 to 10To describe this embodiment, the difference between this embodiment and Embodiment VIII is that the barrel 24 includes a mixing section 241, a tapered transition section 242, and a discharging section 243. The mixing section 241, the tapered transition section 242, and the discharging section 243 are coaxially arranged in sequence from top to bottom. The top cover 15 is installed at the top end of the mixing section 241. The bottom end of the mixing section 241 is communicatively connected to the large end of the tapered transition section 242. The small end of the tapered transition section 242 is communicatively connected to the top end of the discharging section 243. The bottom end of the discharging section 243 is correspondingly arranged with a material receiving component 26 located on the bottom tray 1. The material distribution assembly 21 and multiple mixing and stirring assemblies 22 are located in the mixing section 241. The guiding screw blade 23 is located in the tapered transition section 242. Other components and connection relationships are the same as those in Embodiment VIII.

[0050] Embodiment X: In combination with Figures 1 to 10 To describe this embodiment, the difference between this embodiment and Embodiment IX is that a on-off valve is installed on the discharging section 243. Other components and connection relationships are the same as those in Embodiment IX.

[0051] Combined with Embodiments IX and X, the three-section barrel design can ensure the smooth discharge through the tapered surface while ensuring the full and uniform mixing of the powder materials. The on-off valve on the discharging section 243 can control the working state of the discharging section 243. To observe the height of the powder materials in the mixing section 241, vertical observation strip holes can be machined on the outer wall of the mixing section 241, and tempered glass can be dry-mounted in the holes to prevent the powder materials from leaking out;

[0052] In order to ensure the tight installation of the top cover 15 and the barrel 24, a plurality of auxiliary pressing structures are also arranged at equal circumferential intervals on the outer circumferential surface of the top of the barrel 24. The auxiliary pressing structure includes a connecting block 244, a connecting vertical rod 245 and a swinging pressing block 246. At the same time, a nut 27 and a screw rod 28 are also used in cooperation with the auxiliary pressing structure. The connecting block 244 is fixed on the outer circumferential surface of the top of the barrel 24. The connecting vertical rod 245 is erected vertically on the top of the connecting block 244, and the connecting vertical rod 245 is fixedly connected with the connecting block 244. The swinging pressing block 246 is arranged on the top of the connecting vertical rod 245, and one end of the swinging pressing block 246 is hinged to the connecting vertical rod 245. A first through hole is machined at the top of the other end of the swinging pressing block 246. When the swinging pressing block 246 swings to the top of the top cover 15, a second through hole is machined at the corresponding position on the top cover 15. A threaded blind hole is machined at the corresponding position of the top end of the barrel 24 and the second through hole. When performing auxiliary pressing, first install the top cover 15 on the top of the barrel through the sealing ring 19, and ensure that the second through hole and the threaded blind hole are coaxially corresponding. At this time, swing the swinging pressing block 246 above the top cover 15, so that the bottom end of the screw rod 28 passes through the first through hole and the second through hole in sequence and finally inserts into the threaded hole and is threadedly connected with the threaded hole. At this time, sleeved the nut 27 on the screw rod 28 and tighten the nut 27 by screwing, so that it presses on the swinging pressing block 246 and drives the swinging pressing block 246 to press the top cover 15.

[0053] The present utility model has been disclosed above with a preferred embodiment. However, it is not intended to limit the present utility model. Any person skilled in the art, within the scope of the technical solution of the present utility model, can make some changes or modifications to the above-disclosed structure and technical content to form an equivalent embodiment of equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model still fall within the scope of the technical solution of the present utility model.

[0054] Working principle:

[0055] When the utility model is in use, first assemble each component according to the connection relationship described in the first to tenth specific embodiments. When it is used for the first time, adjust the on-off valve on the discharge section 243 of the barrel 24 to a blocking state to ensure that the discharge section 243 is in a closed working condition. At this time, adjust the basal fertilizer guiding unit and the macronutrient guiding unit to the working position through the sliding mechanism 5, ensure that the feeding end of the basal fertilizer transition barrel 7 is correspondingly arranged with the feeding port of the basal fertilizer feeding device, the discharge port of the basal fertilizer transition barrel 7 is correspondingly arranged with the basal fertilizer feeding conduit 16 in the mixing unit, the feeding port of the macronutrient transition barrel 10 is correspondingly arranged with the feeding port of the macronutrient feeding device, and the discharge port of the macronutrient transition barrel 10 is correspondingly arranged with the macronutrient feeding conduit 17 in the mixing unit. According to the proportion of each element in the compound fertilizer to be configured, adjust the working position of the flow regulating block 121 in each transition sub-barrel of the macronutrient transition barrel 10. For example, if the mass proportion of the basal fertilizer in compound fertilizer A is 70%, and the proportions of nitrogen fertilizer, phosphate fertilizer, and potassium fertilizer are all 10%, then on the premise of ensuring that the aperture of the basal fertilizer guiding pipe 8 is the same as that of the macronutrient guiding pipe 11, adjust each flow regulating block 121 to block 6 / 7 of the interface between the corresponding macronutrient guiding pipe 11 and the discharge pipe, and ensure that the flow rate of each element fertilizer of nitrogen fertilizer, phosphate fertilizer, and potassium fertilizer is 1 / 7 of the flow rate of the basal fertilizer.That is, within a fixed time, the mass ratio of the base fertilizer to the mass of each elemental fertilizer is 7:1 (a flow adjustment structure can also be set in the base fertilizer guiding pipe 8. When ensuring that the aperture of the base fertilizer guiding pipe 8 is the same as that of the large elemental nutrient guiding pipe 11, at this time, the flow rate of the base fertilizer guiding pipe 8 is adjusted to 7 / 10, and the flow rate of each large elemental nutrient guiding pipe 11 is adjusted to 1 / 10, which can also achieve the above effect. And when ensuring that the aperture of the discharging section 243 is larger than that of the base fertilizer guiding pipe 8 or the large elemental nutrient guiding pipe 11, continuous mixing work can be achieved). After the flow rate adjustment of each large elemental nutrient corresponding to the transition sub-cylinder is completed, start the base fertilizer feeding device and the large elemental nutrient feeding device to perform the feeding action. Since the discharging section 243 is in a closed working condition and a guiding screw propeller 23 is arranged in the conical transition section 242 of the material cylinder 24, most of the powder materials will be accumulated in the mixing section 241 under the blockage of the guiding screw propeller 23. When it is observed through the strip-shaped hole that the powder materials are accumulated to 1 / 2 of the total height of the mixing section 241, start the motor 14 to drive the rotating structure to rotate through the motor 14. The powder materials in the mixing section 241 are fully stirred by the double-oblique stirring blades on the mixing and stirring assembly 22. When the height of the powder materials rises to 2 / 3 of the total height of the mixing section 241, the pre-fed powder materials have been mixed. At this time, open the on-off valve on the discharging section 243 to ensure that the discharging section 243 is in a flowing working condition. The mixed powder materials in the material cylinder 24 will be discharged from the discharging section 243. It should be noted that since the guiding screw propeller 23 has transported the powder materials that have not been fully mixed to the conical transition section 242 at the initial stage of the working of the rotating structure, the mixing degree of the powder materials discharged in the initial stage is not very sufficient. Therefore, the mixed powder materials discharged in the first 1-2 minutes of work can be collected and centrally processed, and are not directly used for subsequent working conditions. The mixed powder materials discharged after working for 1-2 minutes are collected through the receiving assembly 26 or directly transported to the next working condition through the conveyor belt.,
