Description

Technical Field

[0001] The invention relates to the field of land detection, and in particular to a soil processing device for land humus detection. Background Art Soil refers to a loose layer of material on the surface of the earth, composed of various granular minerals, organic matter, water, air, microorganisms, etc., and can grow plants. Soil is composed of minerals formed by weathering of rocks, organic matter produced by the decomposition of animal and plant and microbial residues, soil organisms (solid phase matter), water (liquid phase matter), air (gas phase matter), oxidized humus, etc. Among them, soil humus is a special form of organic matter in the soil. It is a complex macromolecular compound with special chemical and biological properties, and is the main form of soil organic matter.

[0002] In the prior art, soil humus detection operations usually require the use of soil processing devices. In order to ensure the accuracy of the test results, it is usually necessary to screen the soil samples into components of multiple different particle sizes to ensure the diversity of test data for different particle sizes. Most of the existing soil processing devices are performed by the staff using a grinding mechanism to initially grind and crush the soil to make the soil smaller particles, and use a screening mechanism to screen the granular soil into soil particles of different particle sizes. Then, soil humus detection equipment (such as: soil nutrient analyzer, infrared spectrometer, etc.) can be used to perform humus detection operations on soil samples of different particle sizes in turn. In the above-mentioned prior art solutions, the staff needs to gradually complete the grinding and screening steps. During the screening operation, the screening device needs to be manually shaken to ensure the soil screening effect, and in order to screen soil particles of different particle sizes, screening devices with different apertures need to be replaced, which results in numerous work steps. Summary of the invention

[0003] The technical problem to be solved by the present invention is to address the shortcomings of the existing technology mentioned in the background technology, and to provide a soil treatment device for land humus detection with a grinding-screening-dust collection linkage mechanism that can guide the rotational power of the grinding mechanism into a vertical oscillating motion, drive the screening component to enable efficient screening, and at the same time link the dust collection system to enable efficient dust collection.

[0004] The present invention is realized through the following technical scheme: it comprises a frame and a grinding base fixedly mounted on the upper end of the frame, the upper end of the grinding base is rotatably connected to a grinding disc, and the upper end of the grinding base is fixedly connected to a power input rod; the characteristics are: a detachable multi-stage screening assembly is arranged in the frame, which is used for screening ground soil particles; an outer disc is fixedly connected to the outer periphery of the grinding disc through a connecting rod, and a toggle seat is formed at the lower end of the outer disc; at least one oscillation rod is movably mounted in the frame, and a toggle rod is fixedly mounted at the upper end thereof corresponding to the toggle seat, which is used for transmitting the rotational power of the outer disc to the oscillation rod, so that it performs vertical reciprocating oscillation motion under the action of an oscillation spring; at least one oscillation transmission cylinder is arranged on the oscillation rod, which is connected to the screen plate assembly to convert the oscillation force into screening power.

[0005] By adopting the above technical solution, the grinding disc can rotate under the action of an external power source through the power input rod, so that the soil particles entering the grinding base can be ground and crushed. The ground and crushed soil particles will enter the frame and be screened into soil samples of different particle sizes by the multi-stage screening component. Among them, the oscillation rod can convert the rotational power of the outer disc located on the periphery of the grinding disc into a vertical reciprocating oscillation motion under the linkage action of the shifting rod and the shifting seat, and use the oscillation motion to drive the multi-stage screening component to vibrate and shake, so as to improve its screening effect.

[0006] In a specific technical solution, the multi-stage screening assembly includes a primary screen plate, a secondary screen plate and a tertiary screen plate, and a receiving bottom plate is slidably inserted into the bottom end of the frame through a guide rail.

[0007] By adopting the above technical scheme, the screening particle sizes of the first-stage sieve plate, the second-stage sieve plate and the third-stage sieve plate can be gradually reduced from top to bottom, so that soil samples of various particle size specifications can be screened, and the receiving bottom plate can receive the soil samples passing through the bottom sieve plate.

[0008] In the specific technical solution, there are two oscillation rods, namely a low-frequency oscillation rod and a high-frequency oscillation rod, both of which are connected to the frame through an oscillation spring. The corresponding toggle seat is divided into a low-frequency toggle seat and a high-frequency toggle seat. The low-frequency oscillation rod corresponds to the low-frequency toggle seat through the toggle rod, and the high-frequency oscillation rod corresponds to the high-frequency toggle seat through the toggle rod.

[0009] By adopting the above technical solution, the low-frequency oscillation rod and the high-frequency oscillation rod can produce oscillation effects of different frequencies to ensure the diversification of the vibration and shaking effects of the screen plate under the linkage mechanism and the diversification of the frequency of the knocking handle hitting the dust filter.

[0010] In the specific technical scheme, there are three oscillation transmission cylinders, each including an upper oscillation cylinder, a lower oscillation cylinder and an abutment slide cylinder. The upper oscillation cylinder and the lower oscillation cylinder are symmetrically distributed and fixedly installed on the oscillation rod. The abutment slide cylinder is respectively located in the upper oscillation cylinder and the lower oscillation cylinder, and is connected by an abutment spring. The first-level sieve plate, the second-level sieve plate and the third-level sieve plate are all slidably embedded between the abutment slide cylinders through abutment slots.

[0011] By adopting the above technical scheme, the first-level sieve plate, the second-level sieve plate and the third-level sieve plate can establish a detachable connection relationship with the oscillation transmission cylinder through the abutment slot, thereby satisfying the detachable effect of the screening component. At the same time, the abutment slide cylinder can slide in the abutment slide groove, thereby satisfying the up and down shaking of the screening component during the vibration movement.

[0012] In a specific technical solution, magnetic handles are formed on the two end walls of the primary sieve plate, the secondary sieve plate and the tertiary sieve plate, and a rotating slot is opened at the connection between the frame and the magnetic handle. A rotating disk is rotatably connected to the rotating slot through a bearing, and the end of the rotating disk away from the magnetic handle is fixedly connected to a torsion spring rod, and the end of the rotating disk adjacent to the magnetic handle is fixedly connected to a magnetic rod, and the magnetic handle and the magnetic rod are magnetically adsorbed and connected.

[0013] By adopting the above technical scheme, the magnetic adsorption connection between the magnetic handle and the magnetic rod can meet the detachable effect of the screening assembly, and at the same time can provide a resetting effect for the screening assembly under the action of the torsion spring rod, which not only increases the vibration and shaking effect of the screening assembly, but also facilitates the disassembly and assembly of the screening assembly.

[0014] In the specific technical solution, a dust collector is also installed below the screening assembly in the frame to absorb and collect dust particles generated by screening. Knocking handles are arranged on both sides of the dust collector, and an abutment cone is formed at the lower end of the oscillation rod. During the oscillation motion, the abutment cone impacts the back of the knocking handle each time it descends, forcing the knocking handle to rotate and knock and vibrate the dust filter of the dust collector.

[0015] By adopting the above technical scheme, while the oscillation rod drives the multi-stage screening assembly to vibrate and shake, the abutment cone is used to link the knocking handle, so that the knocking handle can use the oscillating movement of the oscillation rod to knock on the dust filter of the dust collector to make it vibrate, so that the dust attached to its surface can fall off, thereby ensuring the efficient dust collection operation of the dust collector. In addition, the dust particles falling off the dust filter can also be used as a soil sample to participate in the humus detection operation.

[0016] In a specific technical solution, one end of the dust collector is rotatably connected to a rotating shaft, the dust filter is rotatably connected to the dust collector via the rotating shaft, and the dust collector and the dust filter are connected via a reset torsion spring.

[0017] By adopting the above technical solution, the dust collecting filter can rotate with the rotating shaft as the center, and can be attached to the air inlet of the dust collector under the action of the reset torsion spring to ensure its dust collecting effect.

[0018] In a specific technical solution, force plates are fixedly connected to both sides of the dust filter, and the force plates correspond to the knocking handles. Mounting seats are fixed on the outside of the knocking handles in the frame, and the mounting seats are rotatably connected to the knocking handles through a torsion spring connecting shaft. The torsion spring connecting shaft is located at the lower end of the knocking handle, and the knocking handle rotates around the torsion spring connecting shaft as the center of the circle.

[0019] By adopting the above technical solution, the knocking handle can transmit the striking force to the dust filter through the force plate, forcing the dust attached to the dust filter to fall off, and the mounting base can provide a supporting effect for knocking through the torsion spring connecting shaft, so that the knocking handle can rotate and knock with the torsion spring connecting shaft as the center of the circle, and can be reset under the action of its torsion spring to meet the next knocking movement.

[0020] In a specific technical solution, a discharge port is formed at one end of the primary sieve plate, the secondary sieve plate and the tertiary sieve plate, and the discharge port passes through the frame. A pull-out handle is fixedly connected to the outer wall of the primary sieve plate, the secondary sieve plate, the tertiary sieve plate and the supporting bottom plate.

[0021] By adopting the above technical solution, the discharge outlet can discharge the soil particles screened by the primary sieve plate, the secondary sieve plate and the tertiary sieve plate out of the frame, and the pull-out handle can facilitate the disassembly and assembly of the primary sieve plate, the secondary sieve plate, the tertiary sieve plate and the receiving bottom plate.

[0022] In a specific technical solution, the discharge ports of the primary sieve plate, the secondary sieve plate and the tertiary sieve plate are all centrally distributed or arranged in sequence.

[0023] By adopting the above technical solution, the centrally distributed discharge outlets can discharge the soil particles sieved by sieve plates of different heights from positions at different heights, while the discharge outlets arranged in sequence can discharge the soil particles sieved by the sieve plates from different positions to adapt to different sample collection devices.

[0024] Compared with the prior art, the present invention has the following beneficial effects: The present invention can transform the rotational power of the grinding mechanism into a vertical reciprocating oscillating motion by setting a transmission seat with different transmission ratios and cooperating with a plurality of oscillation rods with different frequencies, and utilize a plurality of oscillation transmission cylinders to drive a plurality of screen plates to vibrate and shake at a plurality of frequencies, so that the corresponding screening operations can be completed efficiently and the manual operation steps of the staff can be reduced. At the same time, a dust collection system is built in, and a knocking handle is linked with an abutment cone during the operation of the dust collector, so that the knocking handle can utilize the oscillation impact force of oscillation rods of different frequencies to knock the dust filter of the dust collector, forcing the dust attached to the surface to fall off, thereby achieving its efficient dust collection effect. At the same time, with the help of its suction-type negative pressure dust collection effect, not only the screening effect of the screen plate is further improved, but also dust floating to pollute the surrounding ambient air can be avoided, thereby avoiding affecting the health of the staff.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] like Figure 1-Figure 3 As shown, a soil processing device for land humus detection in this embodiment includes a frame 1 and a grinding base 201 fixedly installed on the upper end of the frame 1, the upper end of the grinding base 201 is rotatably connected to a grinding disc 202, and the upper end thereof is fixedly connected to a power input rod 205, the power input rod 205 is externally connected to the power output end of the motor, and is used to transmit the power of the motor to the grinding disc 202, so that the grinding disc 202 rotates to grind and crush the soil particles entering the grinding base 201; There are multiple sieve plates detachably connected in the frame 1, which are a primary sieve plate 301, a secondary sieve plate 302 and a tertiary sieve plate 303. The multiple sieve plates are used to screen the ground soil particles to complete the multi-stage screening operation of the soil; one end of the multiple sieve plates is provided with a discharge port 306, and the discharge port 306 runs through the frame 1, so that the soil that has completed the multi-stage screening operation is discharged from the frame 1 through the corresponding discharge port 306. At the same time, a receiving bottom plate 304 is slidably connected to the bottom end of the frame 1 through a slide rail to receive the soil particles that have passed through the bottom sieve plate. A pull handle 307 is fixedly connected to the outer side walls of the multiple sieve plates and the receiving base. The multiple sieve plates and the receiving base can be pulled out and separated from the frame 1 by the pull handle 307, and can also be inserted and installed again; in this embodiment, the opening position of the discharge port 306 can be as shown in the figure. Figure 2 As shown, they are uniformly centered, or they can be Fig.18 As shown, the discharge ports 306 are arranged in a left-middle-right order, so that the discharge ports 306 can simultaneously load the discharged soil samples into the corresponding containers below.

[0029] like Figure 1 , Figure 4 and Fig.12As shown, the outer periphery of the grinding disc 202 is fixedly connected to the epitaxial disc 203 through a connecting rod 204, and a toggle seat is formed at the lower end of the epitaxial disc 203; an oscillation rod 4 is installed in the frame 1, and a toggle rod 404 is fixedly installed at the upper end corresponding to the toggle seat, and the low-frequency oscillation rod 401 and the high-frequency oscillation rod 402 are both installed and connected to the frame 1 through an oscillation spring 403, and the corresponding toggle seat is divided into a low-frequency toggle seat 206 and a high-frequency toggle seat 207. The low-frequency oscillation rod 401 corresponds to the low-frequency toggle seat 206 through the toggle rod 404, and the high-frequency oscillation rod 402 corresponds to the low-frequency toggle seat 207 through the toggle rod 4 04 corresponds to the high-frequency toggle seat 207; when the grinding disc 202 is in the rotational motion of grinding, the toggle seat will be displaced synchronously, and the corresponding toggle rod 404 will be impacted by the collision of the toggle seat to cause the oscillation rod 4 to be displaced downward, and the oscillation rod 4 will be reset by the oscillation spring 403 after the downward displacement, and will be displaced downward again when the toggle seat impacts the next time, thereby realizing the vertical reciprocating oscillation motion; in this embodiment, the low-frequency oscillation rod 401 and the high-frequency oscillation rod 402 can perform oscillation operations of corresponding frequencies under the action of toggle seats of different frequencies; In order to ensure the stability of the impact and collision effect, the lower end surface of the toggle seat can adopt a wedge-shaped structure or an arc structure, and correspondingly, the upper end surface of the toggle rod 404 adopts a matching structural feature, and lubricating oil can be applied on its contact surface to increase the stability of its transmission effect. At the same time, the spring strengths of the oscillation spring 403 equipped with the low-frequency oscillation rod 401 and the oscillation spring 403 equipped with the high-frequency oscillation rod 402 are different to meet the oscillation effects of different frequencies and different intensities. For example, the stiffness of the oscillation spring 403 of the low-frequency oscillation rod 401 is 80-100N / m, while the stiffness of the oscillation spring 403 of the high-frequency oscillation rod 402 is 300-350N / m. Among them, the stiffness of the oscillation spring 403 of the low-frequency oscillation rod 401 is small, so that the low-frequency oscillation rod 401 can Complete a deeper and longer oscillation stroke, and the oscillation spring 403 of the high-frequency oscillation rod 402 has a large stiffness, so that the high-frequency oscillation rod 402 can complete a shorter and faster oscillation stroke, thereby meeting the oscillation requirements of different frequencies. In addition, the protruding heights of the toggle seat are different. For example, the protruding height corresponding to the low-frequency oscillation rod 401 is 3 cm, and the protruding height corresponding to the high-frequency oscillation rod 402 is 1 cm. In this solution, the toggle seat corresponding to the low-frequency oscillation rod 401 will cause a stronger collision impact on the low-frequency oscillation rod 401, and the toggle seat corresponding to the high-frequency oscillation rod 402 will cause a lighter collision impact on the high-frequency oscillation rod 402, so that the high-frequency oscillation rod 402 can be quickly reset under the action of the corresponding oscillation spring 403 to meet the collision impacts of high and low frequencies and different intensities.

[0030] In another embodiment, the linkage mechanism between the shift seat and the shift rod 404 can replace the outer disc 203 with a conical bottom, and configure teeth of different heights and densities on the conical annular surface to form a bevel gear structure with multiple transmission ratios. Fig.12Similarly, the same technical effect can be achieved by using teeth of different densities to impact the lever 404; in addition, the teeth of different heights and densities on the conical annular surface can be transformed into wave-shaped concave-convex structures of different heights and different undulation frequencies. The wave-shaped concave-convex structures of different heights and different undulation frequencies here can continuously abut the corresponding lever 404, and use the wave-shaped concave-convex structures to force the corresponding lever 404 to reciprocate downward displacement under the drive of the epitaxial disk 203. However, the wave-shaped concave-convex structure here lacks the impact force of the shock, so the use effect is not as good as the toothed toggle seat of the conical epitaxial disk 203 and the Fig.12 Toggle seat shown.

[0031] like Figure 4-Figure 7 As shown, three oscillation transmission cylinders 405 are arranged on the oscillation rod 4, corresponding to the primary sieve plate 301, the secondary sieve plate 302 and the tertiary sieve plate 303 respectively. The oscillation transmission cylinder 405 includes an upper oscillation cylinder 4051, a lower oscillation cylinder 4052 and an abutting slide cylinder 4053. The upper oscillation cylinder 4051 and the lower oscillation cylinder 4052 are symmetrically distributed and fixedly installed on the oscillation rod 4. The abutting slide cylinder 4053 is respectively located in the upper oscillation cylinder 4051 and the lower oscillation cylinder 4052 and is connected by an abutting spring 4054. The primary sieve plate 301, the secondary sieve plate 302 and the tertiary sieve plate 303 are all slidably embedded in the abutting slide cylinder 405 through the abutting slot 305. 3, when the oscillation rod 4 performs reciprocating oscillation motion downward, its oscillation force can be transmitted to the abutment slide 4053 through the abutment spring 4054, and the abutment slide 4053 transmits the oscillation force to the primary sieve plate 301, the secondary sieve plate 302 and the tertiary sieve plate 303 respectively, so that the oscillation force of the oscillation rod 4 can be converted into the vibration force of the sieve plate, thereby promoting the screening effect of the sieve plate; during the vibration of the sieve plate, the sliding and plug-in relationship between the abutment slot 305 and the abutment slide 4053 can meet the up and down shaking rotation displacement effect of the sieve plate. In this embodiment, the two oscillation rods 4 with different frequencies can provide the sieve plate with vibration effects of different intensities and different frequencies.

[0032] like Figure 8-Figure 11As shown, in order to ensure that the sieve plate can vibrate and shake smoothly under the drive of the oscillation rod 4, magnetic handles 504 are formed on the two end walls of the primary sieve plate 301, the secondary sieve plate 302 and the tertiary sieve plate 303, and a rotating slot 505 is provided at the connection between the frame 1 and the magnetic handle 504. The magnetic handle 504 can rotate in the rotating slot 505, thereby meeting the basic structural connection requirements for the vibration and shaking of the primary sieve plate 301, the secondary sieve plate 302 and the tertiary sieve plate 303. At the same time, in order to further enhance the screening effect of the vibration and shaking of the primary sieve plate 301, the secondary sieve plate 302 and the tertiary sieve plate 303 and the reset effect after the vibration and shaking, the frame 1 is provided with a rotating slot 505. A rotating disk 501 is rotatably connected in the groove 505 via a bearing, and a torsion spring rod 502 is fixedly connected to one end of the rotating disk 501 away from the magnetic handle 504, and a magnetic rod 503 is fixedly connected to one end of the rotating disk 501 adjacent to the magnetic handle 504. The magnetic handle 504 and the magnetic rod 503 are magnetically adsorbed and connected. When the sieve plate vibrates and shakes, the rotating disk 501 can be driven to rotate synchronously through the magnetic handle 504 and the magnetic rod, and the torsion spring rod 502 can reset the rotating disk 501 after rotation, thereby driving the sieve plate to reset again after rotation, thereby achieving not only the screening effect of enhancing the vibration and shaking of the sieve plate, but also the reset effect of the sieve plate after vibration and shaking. In addition, when the sieve plate is pulled out of the frame 1, the magnetic handle 504 can break free from the magnetic adsorption connection effect between it and the magnetic rod 503, so that the sieve plate can be smoothly pulled out; when the sieve plate is inserted into the frame 1, the magnetic handle can re-establish the magnetic connection effect with the magnetic rod 503, thereby satisfying the flexible disassembly and assembly effect of the sieve plate.

[0033] like Figure 13-Figure 17 As shown, a dust collector 6 is also installed below the screening assembly 3 in the frame 1, which is used to absorb and collect dust particles generated by the first-stage sieve plate 301, the second-stage sieve plate 302 and the third-stage sieve plate 303 during the screening process. Both sides of the dust collector 6 are provided with knocking handles 605, and the lower end of the oscillation rod 4 is formed with an abutment cone 406. When the oscillation movement is performed, each time the abutment cone 406 descends to impact the back of the knocking handle 605, the knocking handle 605 is forced to rotate to knock and vibrate the dust filter 601 of the dust collector 6, so that the dust particles adsorbed on the dust filter 601 can be shaken off, thereby ensuring the efficient operation effect of the adsorption-type dust collection of the dust filter 601; like Fig.14 and Fig.15As shown, one end of the dust collector 6 is rotatably connected to a rotating shaft 602, and the dust filter 601 is rotatably connected to the dust collector 6 via the rotating shaft 602. The dust collector 6 and the dust filter 601 are connected via a reset torsion spring 603, wherein the rotating shaft 602 enables the dust filter 601 to rotate around the rotating shaft 602 as the center after being struck, and the reset torsion spring 603 enables the dust filter 601 to reset after being struck and unload the force, and vibrate and shake, thereby causing the dust particles adsorbed on the dust filter 601 to vibrate and fall off; like Fig.15 and Fig.16 As shown, both sides of the dust filter 601 are fixedly connected with a force plate 604, and the force plate 604 corresponds to the knocking handle 605; the knocking handle 605 will knock the force plate 604 after being impacted by the oscillation rod 4, and the force plate 604 will transfer the impact force to the dust filter 601 to meet the shaking and vibration effect of the dust filter 601; the oscillation rod 4 with different oscillation frequencies can perform impact operations of different frequencies on the corresponding knocking handle 605, and then the corresponding knocking handle 605 completes the knocking operations of different frequencies, so that the dust filter 601 can be subjected to the shaking and vibration effects of different frequencies and different intensities, thereby improving the shedding efficiency of dust particles attached to its surface.

[0034] like Fig.17 As shown, a mounting seat 607 is fixed on the outer side of the knocking handle 605 in the frame 1, and the mounting seat 607 is rotatably connected to the knocking handle 605 through a torsion spring connecting shaft 606. The torsion spring connecting shaft 606 is located at the lower end of the knocking handle 605, and the knocking handle 605 rotates around the torsion spring connecting shaft 606. The mounting seat 607 can provide a supporting connection basis for the knocking handle 605 through the torsion spring connecting shaft 606, and use the torsion spring on the torsion spring connecting shaft 606 to reset the knocking handle 605 that has been impacted after unloading the force after the knocking action is completed, so as to wait for the next impact effect of the oscillation rod 4 and complete the knocking effect again.

[0035] The embodiment of the present invention provides a soil treatment device for soil humus detection with a grinding-screening-dust collection linkage mechanism, which can convert the rotational power of the grinding mechanism into a vertical oscillating motion, drive the screening component 3 to enable efficient screening, and simultaneously link the dust collection system to enable efficient dust collection. This solves the problem in the prior art that workers need to gradually complete the grinding and screening steps, and during the screening operation, the screening device needs to be manually shaken to ensure the soil screening effect, and in order to screen soil particles of different particle sizes, screening devices of different apertures need to be replaced, resulting in numerous working steps. At the same time, during the grinding and screening operations, dust is easily caused to float and diffuse in the surrounding ambient air, causing damage to the workers. In order to solve the problem of affecting the health of personnel, the overall idea of ​​this embodiment to solve the above problem is: using a transmission seat with different transmission ratios in conjunction with a plurality of oscillation rods 4 with different frequencies to guide the rotational power of the grinding mechanism into a vertical reciprocating oscillation motion, and using a plurality of oscillation transmission cylinders 405 to drive a plurality of screen plates to vibrate and shake, so that they can efficiently complete the corresponding screening operations, and at the same time, during the operation of the dust collector 6, the abutment cone 406 is used to link the knocking handle 605, so that the knocking handle 605 can use the oscillation impact force of the oscillation rods 4 with different frequencies to knock on the dust filter 601 of the dust collector 6, forcing the dust attached to its surface to fall off, thereby achieving its efficient dust collection effect, and at the same time, with the help of its suction-type negative pressure dust collection effect, the screening effect of the screen plate is further improved.

[0036] In this embodiment, the fine dust particles falling off the dust collecting filter 601 can also be used as a soil sample of a particle size to participate in the humus detection operation.
