[0001] The utility model relates to the technical field of agricultural machinery equipment, in particular to a blower protection device for a bale forming module and a forage bale wrapper with the same. Background Art

[0002] With the adjustment of China's agricultural industrial structure and the development of the animal husbandry industry in recent years, the planting area of forage grass has been increasing year by year and the comprehensive utilization of crop straws has been carried out, which puts forward an urgent demand for the collection and storage of forage grass and straws. At present, the most commonly used mechanized harvesting equipment is the square bale wrapper and the round bale wrapper.

[0003] As the core module of the bale wrapper, the bale forming module of the existing square bale wrapper has gradually become stable in terms of structure and function in recent years. However, with the increase of the crushing and dust removal processes in the forage bale wrapper, the dispersion amount of grass strips and dust increases. As the last process of the bale wrapper, the grass strips and dust generated in the previous processes will accumulate in front of the blower of the bale forming module, affecting the effect of the dust removal blower of the bale forming module, aggravating the accumulation of grass strips in the bale forming module, and affecting the bale forming effect and bale forming efficiency. Therefore, ensuring the bale forming rate is a key step to improve the operation efficiency.

[0004] Based on this, it is necessary to develop a blower protection device for a bale forming module to overcome the above technical problems. Summary of the Utility Model

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] Example 1

[0025] like Figure 1 As shown, the fan protection device of the baling module of this embodiment includes a knotter cover 1 and a fan protection cover 2. The middle part of the front side of the knotter cover 1 is provided with a ventilation hole adapted to the fan. The fan protection cover 2 is hinged at the ventilation hole and can be flipped upward to be supported on the top of the knotter cover 1, or flipped downward to cover the ventilation hole. The surface of the fan protection cover 2 is covered with air holes 21, and the side of the fan protection cover 2 close to the ventilation hole is open.

[0026] The fan protection device of the baling module of the present embodiment is a fan protection cover 2 which can be flipped to open or cover the vent at the position of the front vent of the traditional knotter cover 1. Since the fan protection cover 2 is covered with air holes 21, it will not affect the normal ventilation of the fan. The provision of the fan protection cover 2 can prevent grass strips from being drawn into the vent and causing damage to the fan, thereby affecting the baling effect. At the same time, it improves the problem of grass strips piling up in front of the vent of the fan, reducing the air intake and affecting the rotation of the fan. In addition, since the fan protection cover 2 can be flipped up and down, when it is necessary to inspect the inside, the fan protection cover 2 can be flipped up and then the knotter cover 1 can be opened, which will not affect the repair and daily maintenance of the compression module piston, fan and other components.

[0027] In this embodiment, the fan protection cover 2 specifically includes a parallel side panel on each side, a top panel and a front side panel. The front side panel is connected to the front side between the two side panels, and the top panel is connected to the top between the two side panels to form a cover body with an open rear side and a lower part.

[0028] In the present embodiment, the knotter cover 1 comprises a main cover body 11 extending left and right, a left upper cover 12 and a right upper cover 13, the left upper cover 12 and the right upper cover 13 are spaced apart from each other left and right, the front side of the main cover body 11 is hinged to the upper rear parts of the left upper cover 12 and the right upper cover 13 respectively, and can be flipped up and down relatively, the fan protection cover 2 can be flipped downward to be supported on the upper rear end of the left upper cover 12 and the right upper cover 13.

[0029] In this embodiment, the fan protection cover 2 is hinged to the front upper edge of the main cover body 11 through a hinge (indicated by a in the figure). Specifically, at least two hinges are arranged at intervals on the left and right sides of the rear side of the top of the fan protection cover 2, and the fan protection cover 2 is connected and assembled with the top front side of the main cover body 11 through the hinge. Such a structure enables the fan protection cover 2 to be smoothly turned over and abutted against the top of the main cover body 11, which is beneficial to the later maintenance work. Among them, the hinge can be turned over and opened and closed by 180°.

[0030] In this embodiment, a handle 23 for operating the flipping of the fan protective cover 2 is provided on the surface of the fan protective cover 2. Specifically, the handle 23 is arranged at the upper part of the front side plate of the fan protective cover 2. By holding the handle 23, the overall up-and-down flipping of the fan protective cover 2 can be operated, and the operation is relatively convenient.

[0031] As a preferred embodiment, as Figure 2 shown, an extension part 22 protrudes from the lower end of the fan protective cover 2. When the fan protective cover 2 is flipped to support on the upper rear parts of the left upper cover 12 and the right upper cover 13, the extension part 22 is embedded between the rear ends of the left upper cover 12 and the right upper cover 13.

[0032] In the above-mentioned implementation scheme, since there will also be some gaps between the left upper cover 12 and the right upper cover 13 in the ventilation opening, an integrated extension part 22 is provided on the front lower side of the fan protective cover 2. When the fan protective cover 2 is flipped down to block the ventilation opening, the extension part 22 just fits between the rear ends of the left upper cover 12 and the right upper cover 13 and blocks the gap at the corresponding part of the main cover body 11.

[0033] In this embodiment, the front side of the main cover body 11 is set as an inclined surface that slopes downward to the front side. Correspondingly, the rear sides of the two side plates of the fan protective cover 2 are also inclined, ensuring that when the fan protective cover 2 is flipped down and abuts against the front side inclined surface of the main cover body 11, the front side of the fan protective cover 2 is a vertical plane.

[0034] As a preferred embodiment, a position holding component 3 is provided at the upper end of the fan protective cover 2. The fan protective cover 2 can be flipped upward until its upper end abuts against the top of the main cover body 11, and is connected to the top of the main cover body 11 through the position holding component 3.

[0035] In the above-mentioned implementation scheme, the design purpose of the position holding component 3 is that after the fan protective cover 2 is flipped upward and abuts against the top of the main cover body 11, the position holding component 3 can temporarily fix the fan protective cover 2 to the top of the main cover body 11, and it will not easily flip and shake.

[0036] In this embodiment, the above-mentioned position-holding component 3 includes a plurality of magnets spaced apart from each other and disposed at the upper end of the above-mentioned fan protection cover 2, and the main cover body 11 is a stainless steel part that can be adsorbed by the magnets. That is to say, when the fan protection cover 2 is flipped to overlap with the top of the main cover body 11, it can be adsorbed on the top of the main cover body 11 by a plurality of magnets. When it is necessary to open the left upper cover 12 and the right upper cover 13 for maintenance, first open the fan protection cover 2 to make the magnets fit on the top of the main cover body 11 of the knotter cover 1, and then open the left upper cover 12 and the right upper cover 13; when it is necessary to open the knotter cover 1 forward, it is also necessary to first turn up the fan protection cover 2 to fit it with the top of the knotter cover 1, and then turn the knotter cover 1 forward to prevent the fan protection cover 2 from shaking back and forth under the action of gravity.

[0037] Generally, one magnet can be respectively arranged in the left-right direction on the front side of the top of the fan protection cover 2.

[0038] In the above-mentioned implementation scheme, the magnet adopts a shatterproof pot magnet. During installation, the shatterproof pot magnet is overlapped with a nylon washer, and a cross-slot countersunk head screw is passed through the two, and then a flat washer, a spring washer and a type I hexagon nut are added to fix it on the top of the main cover body 11.

[0039] In this embodiment, the above-mentioned air holes 21 are evenly distributed on the front side and the left and right sides of the above-mentioned fan protection cover 2. That is, except for the top and bottom of the fan protection cover 2 where the air holes 21 can be not provided, the side surfaces are all covered with air holes 21 to ensure that ventilation is not affected.
