For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0026] The following is a description of preferred embodiments of the present invention in conjunction with the accompanying drawings.
[0027] See attached Figure 1 The utility model discloses a mulch residue sampling auxiliary device, the overall structure of which includes a frame 1, which is composed of a horizontally arranged support frame and four support legs fixed at the corners of the support frame, and a fixing plate is welded at the bottom of the support leg to increase its stability when placed on field land.
[0028] A motor 2 is fixed on the support frame of the frame 1. The motor 2 is preferably a reduction motor with a self-contained reducer. A screen 3 is slidably mounted on the frame 1. The screen 3 is connected to the motor 2 for driving. The motor 2 drives the screen 3 to reciprocate in the horizontal direction. A diversion bucket 4 is arranged below the screen 3. The diversion bucket 4 is designed with a wide upper opening and a narrow lower opening. The upper opening of the diversion bucket 4 is fixedly connected to the frame 1. The screen 3 consists of a screen wall 30 and a screen bottom 31 movably mounted on the screen wall 30. The inner wall of the screen wall 30 and the upper surface of the screen bottom 31 are both provided with a plurality of split hooks 5. The screen bottom 31 is provided with a plurality of screen holes for small soil particles to fall. The plurality of screen holes are arranged in a regular array. The spacing between each two adjacent screen holes is about 5 cm. The split hooks 5 of the screen bottom 31 are fixed in the gap between the screen holes.
[0029] As a further explanation of this embodiment, refer to the attached Figure 2 The output shaft of the motor 2 is fixedly connected to one end of the first connecting rod 20, the other end of the first connecting rod 20 is hinged to the left end of the second connecting rod 21, the length of the first connecting rod 20 is smaller than the second connecting rod 21, the right end of the second connecting rod 21 is hinged to the left end of the mounting frame 22, and the other end of the mounting frame 22 is detachably fixedly connected to the screen wall 30.
[0030] Specifically, Figure 4As shown, two support blocks 37 are horizontally arranged on the right side of the installation frame 22, and a second groove 32 is formed between the two support blocks 37. A protrusion 33 is fixed on the sieve wall 30, and the protrusion 33 can just be engaged in the second groove 32. A threaded hole 34 is vertically opened on the installation frame 22, and a countersunk hole 35 is vertically opened on the protrusion 33. When the protrusion 33 is engaged in the second groove 32, the threaded hole 34 and the countersunk hole 35 are coaxially aligned. The diameter of the countersunk hole 35 is larger than the diameter of the threaded hole 34, and preferably, the diameter of the countersunk hole 35 is 1.1 times the diameter of the threaded hole 34. The bolt 36 passes through the threaded hole 34 and the countersunk hole 35 of the upper support block 37 of the installation frame 22 and the threaded hole 34 of the lower support block 37 of the installation frame 22 from top to bottom. After installation, the bolt 36 connects the two support blocks 37 and the protrusion 33 together. At this time, the lower end surface of the head of the bolt 36 abuts against the upper end surface of the support block 37 on the upper side.
[0031] As a further explanation of this embodiment, refer to the attached Figure 1 Slide rails 6 are horizontally arranged on both sides of the screen wall 30, and the two slide rails 6 are slidably matched with the slide bars 7. Specifically, a slide groove is opened at the bottom of the slide rail 6, and the slide bar 7 is arranged in the slide groove and moves along the slide groove. The slide bar 7 is fixed on a support frame horizontally arranged on the frame 1.
[0032] As a further explanation of this embodiment, refer to the attached Figure 2 The left side of the screen bottom 31 is hinged to the lower part of the screen wall 30 through a hinge shaft 38, and the right side of the screen bottom 31 is in contact with the lower part of the screen wall 30. A sliding roller 8 is installed at the lower right side of the screen bottom 31 for rotation along the front-back direction. Fixed blocks 9 are installed on the inner walls on both the front and rear sides of the frame 1 along the length direction. A first groove 10 is opened on the fixed block 9 along the length direction. The front and rear ends of the sliding roller 8 are respectively slidably set in the first groove 10.
[0033] Among them, Figure 2 As shown, the first groove 10 includes a horizontal section 101 arranged horizontally, the end of the horizontal section 101 is connected and communicated with the head end of the arc section 102, the arc section 102 is arranged in an arc shape, and the end of the arc section 102 is lower than the head end of the arc section 102, that is, the other end of the arc section 102 is arranged lower than the horizontal section 101.
[0034] As a further explanation of this embodiment, refer to the attached Figure 1 and Figure 3 The splitting hook 5 includes a support column 51 fixed on the surface of the sieve wall 30 or the sieve bottom 31. The support column 51 on the surface of the sieve wall 30 is horizontally arranged, and the support column 51 on the surface of the sieve bottom 31 is vertically arranged. The tail ends of multiple arc-shaped hooks 52 are fixed on the support column 51. The number of the arc-shaped hooks 52 is preferably three. The diameter of the arc-shaped hook 52 gradually decreases at the tip part and finally becomes conical.
[0035] The working principle of the utility model is as follows: when in use, the sample soil to be sorted is first placed on the screen 3, and then the motor 2 is started. The output shaft of the motor 2 drives the first connecting rod 20 to revolve around the axis of the output shaft of the motor 2, and the screen 3 is driven to reciprocate in the horizontal direction through the hinge of the first connecting rod 20 and the second connecting rod 21. The fine soil particles will pass through the sieve holes and be screened to the diversion bucket 4 and then fall back to the ground. The ground film mixed in the sample soil will be hooked by the splitting hook 5, and the large soil blocks will constantly collide with the splitting hook 5, and most of them will be split into small soil particles.
[0036] After screening for a period of time, stop the motor 2, take out the ground film from the screen 3 to complete the recycling. At this time, there should be a few large clods of soil remaining in the screen 3. After confirming that there is no ground film on the screen 3, unscrew the bolts 36, separate the mounting frame 22 and the screen 3, and push the screen 3 to the right by hand. At this time, the sliding roller 8 moves along the first groove 10, gradually moving from the horizontal section 101 to the arc section 102. When the sliding roller 8 moves to the arc section 102, due to the downward movement of the sliding roller 8, the left side of the screen bottom 31 is hinged to the lower part of the screen wall 30 through the hinge shaft 38, and the end of the screen bottom 31 close to the sliding roller 8 moves downward accordingly, and the screen bottom 31 becomes inclined, and large clods of soil can slide out to the guide bucket 4 along the screen bottom 31.
[0037] In addition, since the split hooks 5 on the screen bottom 31 may have an impact on the large soil clods, it is only necessary to push and pull the screen 3 back and forth several times by hand to move the large soil clods so that they can roll off the screen 3.
[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, multiple improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
