Description

Technical Field

[0001] The invention relates to a weighing sand collecting device, in particular to a 360-degree omnidirectional continuous weighing sand collecting instrument. Background Art

[0002] Large areas of desertified land and farmland in northern my country have a high risk of soil erosion, so it is particularly important to conduct soil erosion research. Monitoring the structure of wind-sand flow on the surface during wind erosion events is the primary means of conducting soil erosion research. Sand collectors are essential instruments for obtaining field wind erosion materials, studying wind-sand flow structures, and analyzing the laws of wind-sand movement. During soil erosion, the wind direction is variable, and the surface conditions in the surrounding areas are different, resulting in complex and diverse wind-sand flows. In order to study the relationship between wind-sand flow and wind force and surface conditions, we conducted a comprehensive analysis of traditional sand collectors. In traditional sand collectors, most sand collectors can only collect wind-sand flows in pre-set directions, and a small number of them use wind vanes to adjust the direction of the sand inlet, realizing the adjustment of the direction of wind-eroded material collection at any time. However, the wind-eroded materials collected by these instruments are eventually mixed together, and it is difficult for researchers to establish a relationship between the measurement results and wind speed, wind direction, and surface conditions. They are less practical and have lower accuracy, which affects researchers' understanding of the wind-sand flow structure.

[0003] CN109900450B discloses a sand collector, which consists of a sand collecting device and a guide device; the guide device includes a guide mark and a guide rod; the sand collecting device is fixed on the guide rod; under the action of wind force, the guide mark drives the guide rod to rotate, so that the sand collecting port of the sand collecting device is consistent with the wind direction. The wind erosion collected by the sand collector finally enters a sand collecting box, and it is impossible to collect wind erosion from different directions separately, and its protection box is located above the sand collecting port, which seriously affects the airflow field in the direction of the sand collecting port.

[0004] CN109187108B discloses a sand collector and a multi-stage deceleration type automatic sand collector working method. The sand collector includes a wind and sand separation mechanism, which performs multi-stage deceleration on the wind and sand flow to achieve wind and sand separation. Its guide mechanism is connected to the upper end of the wind and sand separation mechanism to ensure that its air inlet is aligned with the wind direction. The sand collector is only provided with one sand collection box, and wind erosion products from all directions are all mixed together, making it difficult to establish the relationship between the measurement result and the wind speed, wind direction and surface conditions, and has poor practicality and low accuracy. Summary of the invention

[0005] The purpose of the present invention is to provide a 360° all-directional continuous weighing sand collector to solve the problem that the existing sand collector cannot separately collect and weigh soil erosion products from different directions when collecting wind-blown sand.

[0006] The object of the present invention is achieved in that: A 360° all-directional continuous weighing sand collecting instrument, comprising: A box body is provided with a fixed seat for clamping the sand storage chamber, a circular opening is provided at the top of the box body, and a circle of water retaining weir is provided around the circular opening; The sand storage chamber is a cylindrical shell, the outer diameter of which is slightly smaller than the diameter of the circular opening at the top of the box body; the sand storage chamber is arranged on a fixed seat in the box body, and the upper edge of the sand storage chamber is higher than the circular opening of the box body, but does not exceed the upper edge of the water retaining weir; The base is a disc structure, which is fixedly arranged in the sand storage chamber. A vertical shaft sleeve is fixed at the center of the top surface of the disc body. The lower section of the main shaft is connected to the shaft sleeve, and the upper section of the main shaft passes through the sand storage chamber. The waterproof cover is a disc cover structure with a downward extending edge. A center hole and a material drop hole are opened on the waterproof cover. The center hole of the waterproof cover is sleeved and fixed on the main shaft, so that the waterproof cover is buckled on the top of the box body, and its disc cover covers the upper opening of the sand storage chamber, and its downward extending edge is blocked at the periphery of the water retaining weir; The sand collecting box is a box body with a fan-shaped cross section. There are several of them, which are symmetrically arranged in the sand storage chamber with the shaft sleeve as the center to form a closed circle. The projection of the drop hole on the waterproof cover falls within the closed circle. A weighing sensor is connected between the bottom surface of each sand collecting box and the base. The sand collecting sand dragon is fixed beside the main shaft through the first connecting arm, the bypass air inlet of which faces outward, and the sand outlet at the lower end thereof is connected with and fixed on the drop hole of the waterproof cover; The fan blade is arranged at the outer end of the second connecting arm, and the inner end of the second connecting arm is fixedly connected to the main shaft. The direction of the fan blade is opposite to the air inlet of the Jishashaklong.

[0007] Furthermore, the sand collecting device of the present invention further comprises: The junction box is fixedly connected to the outer wall of the sand storage chamber, and has a data acquisition module and a communication module built in. The data acquisition module is electrically connected to each weighing sensor to collect weighing information sent by each weighing sensor, and sends the collected weighing information to the outside through the communication module.

[0008] Furthermore, a bearing is arranged between the lower section of the main shaft and the shaft sleeve.

[0009] Furthermore, the first connecting arm and the second connecting arm are arranged on a vertical plane, and the center point of the air inlet of the Jishashaklong is located on the vertical plane.

[0010] Furthermore, a diversion baffle is overlapped on the adjacent edges of two adjacent sand collecting boxes.

[0011] When the wind blows the blades, the direction of the blades changes, driving the main shaft to rotate, so that the air inlet of the sand collector faces the direction of the incoming wind. After the sand collector separates the soil erosion blown in by the wind, it falls into one or two adjacent sand collection boxes in the sand storage chamber through the sand outlet at the lower end, realizing the separate collection of soil erosion from different directions. The weighing sensor obtains the weight and time information of the soil erosion in the corresponding sand collection box, realizing the continuous weighing of the soil erosion collected from different wind directions, thereby achieving the purpose of separate collection and continuous weighing of soil erosion from different wind directions.

[0012] The present invention drives the sand collecting sand slag dragon to rotate with the main shaft through the fan blade, so that the air inlet of the sand collecting sand slag dragon is always facing the incoming wind direction, and the wind and sand flow in the natural environment reaches the air inlet, which reduces the influence on the air flow of the wind and sand field where the sand collector is located. The air inlet of the sand collecting sand slag dragon is perpendicular to the sand storage chamber, away from the center of the main shaft, and closer to the original site outside the sand collector, thereby reducing the influence of the smooth surface of the waterproof cover on the surface conditions and improving the accuracy of collecting soil wind erosion products. Multiple weighing sensors and sand collecting boxes are evenly distributed at different orientations of the base, so that the separate collection of soil wind erosion products from different wind directions is realized, the sampling accuracy of wind erosion product collection is improved, and it is convenient to more accurately grasp the structure of the wind and sand flow. A waterproof cover is installed on the main shaft, and a water retaining weir is set on the box body to block rain and snow falling on the surface of the sand collector from the upper and lower sides, reducing the adverse effects of rain and snow weather on the operation of the sand collector and improving the adaptability of the sand collector in bad weather.

[0020] The base 3 is a disc structure, which is fixed in the sand storage chamber 2 by fixing bolts 13. An upright sleeve 20 is fixed at the center of the top surface of the disc. The lower section of the main shaft 4 is connected to the sleeve 20. A bearing is arranged between the lower section of the main shaft 4 and the sleeve 20 to achieve good rotation of the main shaft 4. The upper section of the main shaft 4 passes through the sand storage chamber 2 to connect the waterproof cover 7, the sand collecting shakron 8 and the fan blade 9 and other components.

[0021] The waterproof cover 7 is a disc cover structure with a downwardly extending edge, a central hole and a material drop hole 15 are opened on the waterproof cover, and the central hole of the waterproof cover 7 is sleeved and fixed on the main shaft 4, so that the waterproof cover 7 is buckled and covered on the top of the box body 1. The disc cover of the waterproof cover 7 covers the upper opening of the sand storage chamber 2, and the downwardly extending edge of the waterproof cover 7 is blocked at the periphery of the water retaining weir 11.

[0022] The sand collecting box 6 is a box body with a fan-shaped cross section, and can be set to 6-8 according to the local wind distribution. The sand collecting box 6 is symmetrically arranged in the sand storage chamber 2 with the shaft sleeve 20 as the center, and forms a closed circle. A diversion baffle 17 is overlapped on the adjacent edges of two adjacent sand collecting boxes. The projection of the drop hole on the waterproof cover 7 falls within the closed circle. A weighing sensor 5 is respectively connected between the bottom surface of each sand collecting box 6 and the base 3 to sense the weight change in the sand collecting box 6 and realize continuous weighing.

[0023] The sand collector 8 is a cyclone separator, and a side air inlet 14 is provided on its shell, and a sand outlet 16 is provided at the lower end of the shell.
