Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of soil improvement equipment, and more particularly to a saline-alkali soil improvement equipment based on zeolite powder. BACKGROUND

[0002] The core feature of saline-alkali soil is the excessive accumulation of soluble salt and alkaline substances in the soil; the excessively high salt concentration not only significantly increases the osmotic pressure of the soil solution, seriously hinders the absorption of water and nutrients by the plant root system, forms "physiological drought", but also directly poisons the root system cells, interferes with their metabolism, and causes poor root development and even death; among them, the large amount of sodium ions existing in the saline-alkali soil can strongly replace the calcium, magnesium and other ions in the soil colloid which play a role in adhesion, this replacement action severely destroys the soil aggregate structure, causes the originally loose and porous soil to collapse, harden and compact, resulting in a sharp decrease in soil permeability, and a serious hindrance to root respiration. The cations (such as Na⁺, K⁺, Ca²⁺) in the zeolite crystal structure reversibly exchange with the salt and alkali ions (such as Na⁺) in the soil, reduce the soil salt concentration by replacing sodium ions, and at the same time supplement calcium, magnesium and other beneficial elements to improve the ion balance of the soil.

DETAILED DESCRIPTION

[0018] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer and more apparent, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0019] Please refer to Figures 1 to 5 , a zeolite powder-based saline-alkali soil improvement equipment provided by the present application will be described. The zeolite powder-based saline-alkali soil improvement equipment comprises a frame body 101, a shell 102 and a soil layering bin 103; the frame body 101 is provided with a traveling wheel 104 at the bottom; the shell 102 is mounted on the frame body 101, and the front and rear sides of the shell 102 are both open structures; the soil layering bin 103 is fixedly installed inside the shell 102, and the soil layering bin 103 is filled with zeolite powder; the soil layering bin 103 divides the inner cavity of the shell 102 into an upper cavity 105 and a lower cavity 106, the front end of the soil layering bin 103 is provided with guide slopes 107 corresponding to the upper cavity 105 and the lower cavity 106, the two guide slopes 107 form a sharp structure, and the two guide slopes 107 are provided with powder outlets 108 for discharging zeolite powder, the powder outlets 108 are in communication with the inner cavities of the soil layering bin 103.

[0020] Compared with the prior art, the frame body 101 walks on the land through the walking wheels 104, the shell body 102 is installed on the frame body 101, and the soil layering bin 103 is fixedly installed in the inside of the shell body 102, so that the shell body 102 and the soil layering bin 103 move synchronously with the frame body 101; the front and rear sides of the shell body 102 are both open structures, the soil layering bin 103 divides the inner cavity of the shell body 102 into an upper cavity 105 and a lower cavity 106, the front end of the soil layering bin 103 is provided with two guide inclined surfaces 107, the two guide inclined surfaces 107 correspond to the upper cavity 105 and the lower cavity 106 respectively, and the two guide inclined surfaces 107 form a sharp structure, the inside of the soil layering bin 103 contains zeolite powder, and the two guide inclined surfaces 107 are both provided with a powder outlet 108 that is in communication with the inner cavity of the soil layering bin 103. When the shell body 102 moves synchronously with the frame body 101, the soil on the land is divided into two layers under the action of the sharp structure at the front end of the soil layering bin 103, and the soil enters the upper cavity 105 and the lower cavity 106 along the two guide inclined surfaces 107 respectively; when the soil passes through the guide inclined surfaces 107, the zeolite powder in the soil layering bin 103 is sprayed on the soil in the upper cavity 105 and the lower cavity 106 through the powder outlets 108 respectively, so that the soil in the two layers can all mix with the zeolite powder, and the soil mixed with the zeolite powder is discharged through the outlets of the upper cavity 105 and the lower cavity 106 respectively. Since the soil in the lower cavity 106 is deep soil, the zeolite powder based saline-alkali soil improvement equipment can spray the zeolite powder on the deep soil, thereby realizing the improvement of the deep soil and improving the soil improvement effect.

[0021] In the embodiment, the four corners of the frame body 101 are provided with support legs 109, the walking wheels 104 are installed at the bottom of the support legs 109, and the support legs 109 are located on both sides of the forward direction of the shell body 102. By arranging the two guide inclined surfaces 107 at the front end of the soil layering bin 103, the resistance of the soil entering the upper cavity 105 and the lower cavity 106 can be reduced.

[0022] In some embodiments, please refer to Figures 1 to 4The first crushing roller 110 is installed on the shell 102, and the front end of the first crushing roller 110 extends to the outside of the shell 102. In this embodiment, the number of the first crushing roller 110 is two, which are respectively installed at the inlet end of the upper cavity 105 and the lower cavity 106. The rotation axis of the first crushing roller 110 is perpendicular to the advancing direction of the shell 102. The soil of the saline-alkali land has the problem of hardening, and its formation mechanism is closely related to the properties of the soil. The pH value of the saline-alkali land soil is usually more than 8.5, which belongs to a strong alkaline environment. The accumulation of salt (such as chloride, sulfate or sodium carbonate) can cause the destruction of the soil particle structure, form a hard surface layer, and then cause hardening. This hardening shows that the soil is muddy when wet, and cracks when dry, and even appears surface whitening or calcium precipitate, so that the soil becomes hard and difficult to disperse. In order to reduce the resistance of the saline-alkali land soil into the shell 102, the first crushing roller 110 is installed on the shell 102. Since the front end of the first crushing roller 110 extends to the outside of the shell 102, the first crushing roller 110 can first crush the hardened soil during the forward movement of the saline-alkali land improvement equipment of the present application, so that the soil can smoothly enter the upper cavity 105 and the lower cavity 106. The crushed soil can be better mixed with zeolite powder, thereby improving the improvement effect on the soil. In addition to crushing the soil, the first crushing roller 110 can also improve the movement rate of the soil, so that the soil can quickly enter the upper cavity 105 and the lower cavity 106.

[0023] In some embodiments, referring to Figures 1 to 4The second crushing roller 111 is installed on the shell 102, and the lower end of the second crushing roller 111 extends to the outside of the shell 102. In this embodiment, in order to make the soil enter the shell 102 smoothly, the lower cavity 106 of the shell 102 should be flush with the depth of the deep soil. When the improvement equipment for saline-alkali soil starts to work, the shell 102 is first lowered into the soil. One way is that the shell 102 moves downward during the movement of the frame 101, the soil is crushed by the first crushing roller 110 located below, and the crushed soil enters the shell 102 after being softened, thereby eliminating the obstruction of the soil in front of the shell 102, and finally the shell 102 is lowered to the predetermined depth. In this way, the lowering speed of the shell 102 cannot be improved when the moving speed of the shell 102 is constant, because the soil below the shell 102 is always in a hardened state. In order to solve the above problem, the second crushing roller 111 is installed at the bottom of the shell 102. The number of the second crushing roller 111 is two, and the second crushing roller 111 is arranged along the moving direction of the shell 102. The axial direction of the second crushing roller 111 is parallel to the axial direction of the first crushing roller 110. Since the lower end of the second crushing roller 111 extends downward to the outside of the shell 102, the second crushing roller 111 can crush the soil directly below the shell 102, so that the soil below the shell 102 is softened. The second crushing roller 111 also has a conveying function. The crushed soil below the shell 102 is automatically conveyed to the rear side of the lower cavity 106 under the action of the two second crushing rollers 111, and the conveying speed of the soil is improved, so that space is provided for the downward movement of the shell 102, and the lowering speed of the shell 102 can be improved when the moving speed of the shell 102 is constant. In order to avoid the soil in the upper cavity 105 from being blocked and to improve the conveying speed of the soil in the upper cavity 105, the third crushing roller 112 is installed on the shell 102. The number of the third crushing roller 112 is two, and the third crushing roller 112 is parallel to the second crushing roller 111. The third crushing roller 112 and the second crushing roller 111 can not only improve the conveying speed of the soil, but also further crush and mix the soil, which can reduce the particle size of the soil and make the soil and zeolite powder fully mixed, thereby improving the improvement effect. The driving motor is installed at the top of the shell 102, and the driving motor drives the first crushing roller 110, the second crushing roller 111 and the third crushing roller 112 to rotate through belt transmission. The driving motor can also drive the first crushing roller 110, the second crushing roller 111 and the third crushing roller 112 to rotate through gear or chain transmission.

[0024] In some embodiments, referring to Figure 4The inner part of the soil layering bin 103 is provided with a partition plate 113, which divides the inner cavity of the soil layering bin 103 into a front cavity 114 and a rear cavity 115. The inner part of the front cavity 114 is used to contain zeolite powder, and the inner part of the rear cavity 115 is used to contain water. The powder outlet 108 is in communication with the front cavity 114, and the rear cavity 115 is provided with a water outlet 116 on the rear side. In this embodiment, the partition plate 113 is a square plate, and the size and shape of the partition plate 113 are the same as the longitudinal cross-sectional size and shape of the soil layering bin 103. Therefore, the partition plate 113 divides the inner cavity of the soil layering bin 103 into two independent front cavity 114 and rear cavity 115. The front cavity 114 contains zeolite powder, and the rear cavity 115 contains water. The powder outlet 108 is in communication with the front cavity 114, and the water outlet 116 is in communication with the rear cavity 115 and is provided on the rear side wall of the soil layering bin 103. Because the soil in saline-alkali land has high salt content, although the zeolite powder can adsorb salt, it still needs to be washed with water. Watering the soil can dilute the salt in the soil, promote the removal of salt with water, and although the pore structure of the zeolite powder can enhance the water retention of the soil and reduce water evaporation, it still needs to be supplemented with water to maintain its improvement effect. The zeolite powder in the front cavity 114 is mixed into the upper and lower layers of soil through the powder outlet 108. After the soil mixed with zeolite powder is discharged from the shell 102, the water in the rear cavity 115 is discharged from the water outlet 116 and sprayed on the soil mixed with zeolite powder. The number of water outlets 116 is multiple and uniformly arranged on the rear side wall of the soil layering bin 103.

[0025] In some embodiments, referring to Figure 2 and Figure 3 The bottom of the frame body 101 is provided with a powder storage tank 117 and a water storage tank 118. The powder storage tank 117 and the water storage tank 118 are in communication with the front cavity 114 and the rear cavity 115 through a pipeline 119, respectively. In this embodiment, the powder storage tank 117 and the water storage tank 118 are fixedly installed on the top surface of the frame body 101. The volume of the powder storage tank 117 and the water storage tank 118 is larger than the inner cavity of the soil layering bin 103, so the powder storage tank 117 and the water storage tank 118 can contain more zeolite powder and water. Because the powder storage tank 117 and the water storage tank 118 are in communication with the front cavity 114 and the rear cavity 115 through the pipeline 119, respectively, the powder storage tank 117 and the water storage tank 118 can supplement zeolite powder and water into the front cavity 114 and the rear cavity 115 through the pipeline 119, respectively, thereby prolonging the uninterrupted working time of the saline-alkali land improvement equipment based on zeolite powder. Because the powder storage tank 117 and the water storage tank 118 are located at the top of the frame body 101, it is also convenient to supplement zeolite powder and water into the powder storage tank 117 and the water storage tank 118, respectively.

[0026] In some embodiments, referring to Figure 2 , Figures 4 to 6The first baffle 120 is hingedly installed outside the powder outlet 108, the first elastic member 121 is installed between the two baffles, the first elastic member 121 is located inside the front cavity 114 and exerts a force on the two first baffles 120 in the opposite direction; the second baffle 122 is hingedly installed outside the water outlet 116, the second elastic member 123 is installed between the second baffle 122 and the inner wall of the soil layering bin 103, and the second elastic member 123 exerts a force on the second baffle 122 towards the side of the water outlet 116; the partition plate 113 is in sliding fit with the inner wall of the soil layering bin 103, and the first driving member 124 for driving the partition plate 113 to move along the front-rear direction of the soil layering bin 103 is installed inside the soil layering bin 103. In this embodiment, the size of the first baffle 120 is larger than that of the powder outlet 108, so the first baffle 120 can cover the powder outlet 108. The hinge shaft of the first baffle 120 is parallel to the first crushing roller 110, and the hinge shaft of the first baffle 120 is located at one end of the first baffle 120 close to the outlet of the shell 102. The guide inclined surface 107 is provided with a groove for accommodating the first baffle 120, the first elastic member 121 is installed between the two first baffles 120, the first elastic member 121 is a tension spring, the first elastic member 121 is located inside the front cavity 114, and the two ends of the first elastic member 121 are fixedly connected with the inner walls of the first baffles 120. The first elastic member 121 exerts a force on the first baffle 120 towards the inside of the front cavity 114, so that the first baffle 120 abuts against the soil layering bin 103, the powder outlet 108 is sealed, and the soil is prevented from entering the front cavity 114. The second baffle 122 is hingedly installed on the rear side wall of the soil layering bin 103, and the second baffle 122 is used to block the water outlet 116. The hinge shaft of the second baffle 122 is parallel to the hinge shaft of the first baffle 120. The number of the second baffles 122 is two, which are located at the upper and lower ends of the rear side wall of the soil layering bin 103, and the hinge shafts of the two second baffles 122 are close to the outlet ends of the upper cavity 105 and the lower cavity 106. The water outlet 116 is provided with two rows of upper and lower water outlets on the rear cavity 115, and the two second baffles 122 block the two rows of water outlets 116. The second elastic member 123 is a torsion spring, which is installed between the second baffle 122 and the hinge shaft thereof. The second elastic member 123 exerts a force on the second baffle 122, so that the second baffle 122 abuts against the rear side wall of the soil layering bin 103. The first driving member 124 is a gas cylinder or an electric push rod, which is installed in the rear cavity 115 in the horizontal direction. Since the rear cavity 115 contains water, the first driving member 124 needs to be waterproof or use a gas cylinder or an electric push rod with waterproof function. The first driving member 124 is fixedly installed on the side wall of the rear cavity 115 opposite to the partition plate 113, and the telescopic rod of the first driving member 124 is fixedly connected with the partition plate 113. The first driving member 124 can also be installed in the front cavity 114.The first driving member 124 drives the partition plate 113 to move reciprocally in horizontal direction. Since the front cavity 114 and the rear cavity 115 are independent of each other, and the front cavity 114 is communicated with the powder storage tank 117 and the rear cavity 115 is communicated with the water storage tank 118, when the first driving member 124 drives the partition plate 113 to move to the side close to the front cavity 114, the pressure of the front cavity 114 becomes larger and the pressure of the rear cavity 115 becomes smaller, and the first baffle 120 is opened, the zeolite powder is sprayed out from the powder outlet 108 under the action of the pressure, at this time, the second baffle 122 is in the closed state, and the water in the water storage cavity is automatically entered into the rear cavity 115 under the action of the pressure, so as to realize the automatic water supplement of the rear cavity 115; when the first driving member 124 drives the partition plate 113 to move to the side close to the rear cavity 115, the pressure of the front cavity 114 becomes smaller and the pressure of the rear cavity 115 becomes larger, the first baffle 120 is closed under the action of the pressure and the first elastic member 121, the zeolite powder in the powder storage tank 117 is entered into the front cavity 114 under the action of the pressure, so as to realize the automatic zeolite powder supplement of the front cavity 114, at this time, the second baffle 122 is opened under the action of the pressure, and the water in the rear cavity 115 is sprayed out from the water outlet 116 under the action of the pressure.

[0027] In some embodiments, see Figure 4 and Figure 5The second baffle 122 comprises an upper baffle 125 and a lower baffle 126, the hinged shaft of the upper baffle 125 is close to the upper cavity 105, the hinged shaft of the lower baffle 126 is close to the lower cavity 106, the upper baffle 125 is provided with an upper flow guide 127, the lower baffle 126 is provided with a lower flow guide 128, and the upper flow guide 127 and the lower flow guide 128 both extend to the rear side of the soil layering bin 103. In the embodiment, the upper baffle 125 is installed at the top of the rear side wall of the soil layering bin 103 and close to the outlet of the upper cavity 105, the lower baffle 126 is installed at the bottom of the rear side wall of the soil layering bin 103 and close to the outlet of the lower cavity 106, and the end close to each other of the upper baffle 125 and the lower baffle 126 is the free end of the two. The upper flow guide 127 is welded and fixed at the upper end of the upper baffle 125, and the lower flow guide 128 is welded and fixed at the lower end of the lower baffle 126. When the water outlet 116 is in a closed state, the top surface of the upper flow guide 127 is flush with the outer contour of the upper cavity 105, and the bottom surface of the lower flow guide 128 is flush with the outer contour of the lower cavity 106. The upper flow guide 127 and the lower flow guide 128 respectively guide the soil in the upper cavity 105 and the lower cavity 106, so that the two streams of soil are kept a certain distance from the water outlet 116 when they leave the device, thereby effectively avoiding the soil from blocking the water outlet 116. When the water outlet 116 is in the opening process, the upper flow guide 127 swings upward with the upper baffle 125, and the lower flow guide 128 swings downward with the lower baffle 126, so that the outlet of the upper cavity 105 and the lower cavity 106 is reduced (the outlet of the upper cavity 105 and the lower cavity 106 will not be completely covered by the upper flow guide 127 and the lower flow guide 128, and the upper flow guide 127 and the lower flow guide 128 will not affect the normal transmission of the soil in the upper cavity 105 and the lower cavity 106), the distance between the upper flow guide 127 and the lower flow guide 128 is increased, and a safety space of the water outlet 116 is formed between the upper flow guide 127 and the lower flow guide 128, and the soil cannot enter the safety space.

[0028] In some embodiments, referring to Figures 1 to 3The top of the shell 102 is provided with a guide support 129, the frame body 101 is provided with a guide rod 130 which is in sliding fit with the guide support 129, the guide rod 130 is arranged along the vertical direction, and a third elastic member 131 is arranged between the guide rod 130 and the guide support 129, the third elastic member 131 exerts an upward supporting force on the guide support 129. In the embodiment, the guide support 129 is welded and fixed on the top surface of the shell 102. The number of the guide supports is four, and they are respectively arranged at the four corners of the top surface of the shell 102. The guide rod 130 is a cylindrical rod, and is welded and fixed on the frame body 101. The guide rod 130 is arranged along the vertical direction and is in sliding fit with the guide support, so that the shell 102 can move along the vertical direction on the frame body 101 under the action of the guide rod 130. The third elastic member 131 is a compression spring, the third elastic member 131 is sleeved on the guide rod 130, the lower end of the guide rod 130 is provided with a limiting flange, the lower end of the third elastic member 131 abuts against the limiting flange, and the upper end of the third elastic member 131 abuts against the guide support 129, so that the third elastic member 131 exerts an upward force on the guide support 129. The frame body 101 provides a supporting force for the shell 102 through the third elastic member 131. When the device of the application is transported under the driving of the tractor, the third elastic member 131 arranged between the frame body 101 and the shell can reduce the bumping of the shell, and plays a buffering and protecting role on the shell. The pipeline 119 is a hose, so it will not affect the up-and-down movement of the shell 102 relative to the frame body 101.

[0029] In some embodiments, referring to Figure 1 and Figure 2A drive rod 132 is hingedly mounted on the frame 101. A support block 133 abuts against the drive rod 132 on the top of the housing 102. A second drive member 134 is fixedly mounted on the frame 101. The second drive member 134 applies a downward force to the free end of the drive rod 132. The support block 133 is located between the hinge axis of the drive rod 132 and the second drive member 134. In this embodiment, the second drive member 134 is a cylinder or an electric push rod, and it is arranged vertically. The drive rod 132 is located above the housing 102. One end of the drive rod 132 is hinged to the frame 101 along its length. The hinge axis of the drive rod 132 is located at the front end of the frame 101, and the other end of the drive rod 132 extends towards the rear of the frame 101. The free end of the drive rod 132 is higher than its hinge axis. The support block 133 is welded and fixed to the top surface of the housing 102. The top surface of the support block 133 is an arc surface, so the support block 133 and the drive rod 132 are in line contact. The hinge axes of the second drive member 134 and the drive rod 132 are located on both sides of the support block 133. The distance between the support block 133 and the second drive member 134 is greater than the distance between the support block 133 and the hinge axis of the drive rod 132. Therefore, using the lever principle, the second drive member 134 applies a downward force to the free end of the drive rod 132, thereby converting the swing of the drive rod 132 around its hinge axis into the downward movement of the housing 102, thus changing the depth of the housing 102 into the soil. When the telescopic rod of the second drive member 134 moves upward, the housing automatically moves upward under the elastic force of the third elastic member 131, eventually returning to the initial height. A pad 135 is fixedly installed on the telescopic rod of the second drive member 134, and the pad 135 is fixed to the telescopic rod of the second drive member 134 by welding. The second drive member 134 abuts against the drive rod 132 via a pad 135. When the second drive member 134 applies force to the drive rod 132, the pad 135 and the drive rod 132 will move relative to each other, resulting in some wear on the pad 135. To extend the service life of the pad 135, it is made of a wear-resistant material. By installing the pad 135 on the telescopic rod of the second drive member 134, the telescopic rod of the second drive member 134 will not directly contact the drive rod 132, thus preventing wear on the telescopic rod of the second drive member 134.

[0030] In some embodiments, please refer to Figure 1 and Figure 3 A connecting frame 136 is fixedly installed on the front side of the frame 101, and the connecting frame 136 is used to connect with the drive equipment. In this embodiment, the connecting frame 136 is welded and fixed to the front side of the frame 101. The drive equipment can be a tractor, and the connecting frame 136 is fixedly connected to the tractor's hook arm by a locking pin. The tractor provides the power for the zeolite powder-based saline-alkali land improvement equipment of this application. The tractor's hook arm can adjust the height of the frame 101.
